Treatments include birth control pills, progesterone, SSRIs (a type of antidepressant), and hormone injections for severe cases, though some treatments still need proof from rigorous trials. Cohort study, 2024 Is PMS before pregnancy linked to postpartum depression? Yes. Women with PMS symptoms before pregnancy were more likely to develop postpartum depression at day 7 to 10 after birth, 6 weeks postpartum, and 6 months postpartum. This association was especially strong in women who had been pregnant multiple times. Survey study, 2024 How common is PMDD in high school students and what factors are linked to it? About one-third of high school students (33.03%) had PMDD. Depression, stress, irregular periods, and longer menstrual bleeding were the strongest linked factors. Survey study, 2024 How common are PMS and PMDD in young Turkish women and what factors are linked to them? PMS affects about 49% of young Turkish women and PMDD about 48%. Blood type B was far more likely to have PMS than blood type A. Lower physical activity, longer menstrual cycles, more caffeine, and depression were also linked to PMDD. Survey study, 2024 What factors are linked to PMS in school-age girls? 22% of these Ethiopian school students had PMS. Heavy coffee drinking and sleep problems were the strongest risk factors, while exercise was protective. Results are from one city in Ethiopia. Survey study, 2024 How common is premenstrual syndrome among healthcare workers? Just over half of healthcare workers had PMS, with the condition significantly linked to sleep habits, diet, physical activity, and BMI. Survey study, 2024 Are calorie tracking and eating disorders linked to menstrual problems in female athletes? 64.6% of resistance-trained athletes tracked calories. Limited connections appeared between body image concerns or eating disorders and menstrual cycle problems. However, there was a clear link between eating disorders and missing periods. Survey study, 2024 Does poor sleep quality cause menstrual problems and reduced egg supply in women of childbearing age? Yes. Women with chronic insomnia had very high rates of PMS (74.5%) and irregular periods (78.4%). In women aged 36 to 40, insomnia lasting over one year was linked to reduced egg reserve (odds ratio 4.5). Survey study, 2024 Do premenstrual disorders affect women's work performance? Yes. Women with premenstrual disorders had worse productivity, work capacity, and daily functioning than women without them. Teachers had more premenstrual disorders than factory workers.

Women with more menstrual symptoms reported more depression, anxiety, stress problems, and sleep issues. Cohort study, 2023 How common are premenstrual symptoms among teenage girls? Over half of teenage girls have premenstrual symptoms like back pain, acne, and mood changes, but 60% do not know that premenstrual syndrome exists. Survey study, 2023 What factors make some women more likely to have PMS or PMDD? Several factors were linked to higher risk of PMS or PMDD: negative Rh blood type, depression, and drinking caffeine more than three times a week. Women who had their first period at a later age had lower risk. Survey study, 2023 Are PMS symptoms linked to loneliness in adolescent girls during COVID-19? Yes. Girls with worse PMS symptoms were more likely to feel lonely. About 29% of girls felt lonely, and 16% of lonely girls had serious psychological distress. Survey study, 2023 Is a history of PMS linked to postpartum depression? Yes. Women with more severe PMS were more likely to experience baby blues (low mood after birth) and postpartum depression. The correlation between baby blues and PMS was 0.397. Cohort study, 2023 Can we predict which nurses will get PMS based on their lifestyle and work conditions? Yes, researchers created a model that could accurately predict which nurses would develop PMS by looking at sleep quality, stress, anxiety, depression, caffeine intake, workplace bullying, and menstrual cycle patterns. The model showed good prediction ability in both test and validation datasets. Case-control study, 2023 Does premenstrual syndrome affect school attendance and grades? Yes, PMS was strongly linked to school absences and lower grades. About 44.2% of students with PMS missed school because of it. Survey study, 2023 How common are PMS and PMDD in first-year medical students? About half (50.6%) had PMS and 8.7% had PMDD. Age at first period, weight, and BMI did not predict who had PMS or PMDD. Survey study, 2023 What menstrual problems do adolescent girls experience? Adolescent girls commonly experience painful periods, heavy periods, and irregular cycles. These problems are often not reported but can affect school attendance and daily life. Cohort study, 2023 Are premenstrual disorders linked to depression, anxiety, and self-harm in teenage girls? Yes. Girls with premenstrual disorders have 4 to 7 times higher rates of depression, anxiety, self-injury, and suicide risk compared to boys and girls without the disorder. This suggests premenstrual disorders may cause much of the difference in mental health problems between teenage boys and girls. Survey study, 2023 How common is PMS in secondary school students and what makes it more likely? About 6 out of 10 secondary school girls had PMS. Girls with period pain, a family history of PMS, or who were overweight were more likely to have PMS, while girls with normal weight were less likely. Survey study, 2023 How common is PMS in high school girls and what helps them cope? PMS was found in 41.2% of high school girls. The most common coping strategies were visiting health clinics (42.6%), listening to music (40.0%), and taking showers (38.0%). Girls with family history or using hormonal birth control were more likely to have PMS. Survey study, 2023 How common are menstrual problems in university students, and do they affect quality of life? Menstrual problems are extremely common, with 98% reporting some problem. The most common are premenstrual symptoms and period pain, both of which significantly reduce quality of life and school attendance. Survey study, 2023 Is stress a risk factor for PMS in young women? Yes. Stress is linked to PMS. More than 3 out of 4 students had PMS, and those with high stress, younger age, irregular exercise, and living away from home were more likely to have it. Survey study, 2023 How common is PMS in working women and does it affect their work-life quality? This survey of 600 working women found that 48% have PMS. Of those with PMS, 35% report lower work-life quality, a statistically significant difference meaning PMS significantly affects work satisfaction. Survey study, 2023 How common is PMS in female college students and does it affect quality of life? 62.7% of 300 female college students had PMS, and it was associated with poorer quality of life across all areas. The most common symptoms were back, joint, and muscle aches. Survey study, 2023 How common are PMS and PMDD in medical students, and does PMS affect work quality of life?

Survey study, 2022 How much does PMDD affect academic quality of life in female college students? In this study of 239 health sciences students, nearly all experienced PMDD symptoms (physical 98.7%, psychological 97.5%, some social 58.2%), and about half said it affected their academic quality of life (46.9%). Survey study, 2022 What are the biggest research gaps in women's health, especially for menstrual conditions? Research is lacking in many important areas, especially communication between women and doctors about health, and support for menstrual conditions like PMDD and heavy periods. There is more research on menopause but not on how to help women manage other conditions. Survey study, 2022 How common are PMS and PMDD? Are stress, anxiety, depression, and sleep problems related to them? About 22.49% of women have PMS and 1.36% have PMDD. Women with these conditions have much higher stress, anxiety, and depression and worse sleep than women without them. Survey study, 2022 How common are PMS and menstrual problems in women on kidney dialysis? Very common. 70% had PMS and 58% had dysmenorrhea. Several medical factors including hypertension, autoimmune disease, and hepatitis C infection increased risk. Systematic review, 2022 Does having PMDD increase the risk of depression during pregnancy or after birth? Yes. Women with PMDD have higher risk of depression after giving birth. Evidence for depression during pregnancy is less clear from current studies. Survey study, 2022 Does eating certain foods increase the risk of PMS? Women with PMS ate more sugary and processed foods, and eating these frequently was linked to higher PMS risk. A diet low in simple sugars is recommended. Survey study, 2022 What factors are associated with irregular menstrual cycles and how do irregular cycles affect other symptoms? Irregular cycles (varying by more than 7 days) affected 21% of nurses. Higher weight, lack of vigorous exercise, shift work, and heavy lifting were associated with irregular cycles. Women with irregular cycles also reported more depression, anxiety, stress, fatigue, and sleep problems. Survey study, 2022 Did the COVID-19 pandemic change women's periods and mental health? Yes. More than half of women reported changes in their menstrual cycle, including more heavy bleeding, painful periods, and missed periods. Rates of depression, anxiety, and poor sleep were more than double what is normal, and these were connected to menstrual changes. Cohort study, 2022 Do women with diabetes have a higher risk of developing PMS? Yes. Women with diabetes are 1.683 times as likely to develop PMS as women without diabetes. Cohort study, 2022 Do women with both bipolar disorder and PMDD have worse biological rhythm disruptions? Yes, women with both bipolar disorder and PMDD experienced greater disruptions in biological rhythms across both the follicular and luteal phases of the menstrual cycle, especially in sleep and activity patterns. Cohort study, 2022 Does living in greener areas reduce PMS symptoms? Yes, women living in greener areas had lower rates of several PMS symptoms including anxiety, depression, sleep problems, and breast tenderness. The effect was modest but consistent. Case-control study, 2022 Does how women think about their period affect how their nervous system responds to stress? Yes. How women view their period (as bothersome or predictable) affects their nervous system response. Women with PMS also show delayed recovery from stress during the premenstrual period. Cohort study, 2022 Does more physical exercise reduce the chance of having PMS in teenage girls? Yes. Girls with at least 2 physical education classes per week were much less likely to have PMS. Those with less than 2 classes per week were 4.43 times more likely to experience PMS. Survey study, 2022 How common is PMS among female college students in China and what increases the risk? About 51% had PMS. Anxiety, stress, smartphone addiction, and painful periods increased risk. Getting more sleep was protective. Randomised trial, 2022 How common are suicidal thoughts in women with PMDD, and what factors are associated with them? About 4 in 10 women with confirmed PMDD reported current suicidal thoughts in the luteal phase. Those with previous psychological treatment and higher depression were more likely to have suicidal thoughts, while better perceived health was protective. We can be confident in this prevalence estimate. Cohort study, 2022 How common are suicidal thoughts and self-harm in people with PMDD? Suicidal thoughts, planning, and attempts are very common in people with PMDD. About 72% report lifetime suicidal thoughts, 49% report planning, and 34% report attempts. Survey study, 2022 How common is PMDD in women and does exercise help? PMDD symptoms are very common (85% of women), with 19% having severe symptoms. Women who do not exercise regularly have worse PMDD, and higher body weight increases severity. Randomised trial, 2022 What research topics and methods have scientists focused on when studying PMS and PMDD? Scientists have focused research on PMS and PMDD primarily through double-blind medication trials, with recent trends shifting toward understanding steroid hormone pathways and genetic factors. Case-control study, 2021 What causes adult female acne and makes it worse? Family history of acne increases your risk of adult female acne, but diet, weight, and premenstrual flare do not. Severity is not related to any of these factors. Survey study, 2021 Is irregular menstrual cycle linked to thoughts of suicide? Women with irregular menstrual cycles were 1.42 times more likely to have suicidal thoughts than women with regular cycles. The association was strongest in younger women, those who started their period early, and those who were employed. Survey study, 2021 Did COVID-19 stress make PMS worse for young women? Young women who experienced trauma symptoms from COVID-19 had more severe PMS symptoms than those without trauma. This observational study cannot prove that COVID stress causes worse PMS. Survey study, 2021 What happens when someone has both bipolar disorder and PMDD? Women with both conditions experience more severe bipolar disorder with more mood episodes and more depression. Treatment is challenging because standard PMDD medication can trigger mania in people with bipolar disorder. Survey study, 2021 Are migraines around the period worse than migraines at other times? Yes. Migraines during the menstrual window last much longer, come back more often, and are more intense than migraines at other times of the cycle. Survey study, 2021 How common is PMS in women of reproductive age and what increases the risk? 47% of 500 women aged 15-49 had PMS. Being younger (15-46), single, a smoker, having painful periods, or having a family history of PMS increased the risk. This is one region so results may differ elsewhere. Cohort study, 2021 Does the menstrual cycle change how brain regions connect with each other? Yes. The menstrual cycle changes how brain regions connect, particularly around ovulation, and these changes relate to estradiol levels and well-being. This is a small study (24 women) so the findings need confirmation in larger groups. Survey study, 2021 What are the menstrual cycle patterns and how common are PMS and PCOS in young Korean women? PMS affected 25.5% of participants and PCOS affected 5.2%. Most women with regular periods had normal cycle length (93% had 21-35 day cycles) and normal duration, though 55.9% reported heavy bleeding. Guideline, 2021 How do premenstrual symptoms affect women's work performance and attendance? Very significantly. Over 90% of the women surveyed reported some premenstrual symptoms, and 40% experienced them moderately or severely. Those with severe symptoms were more likely to be absent from work, arrive late, or leave early. Survey study, 2021 How many female medical students have PMS and how much does it affect schoolwork? Nearly two-thirds of female medical students (64.9%) have PMS, and it significantly interferes with their daily activities and homework. Survey study, 2021 Does premenstrual syndrome affect sleep quality? Yes. Women with PMS had shorter total sleep time, took longer to fall asleep, and had worse sleep quality scores than women without PMS. Survey study, 2021 Does the menstrual cycle affect women's ability to train and compete? Yes. Women who experienced more frequent menstrual symptoms were significantly more likely to miss or change their training, miss competitions, miss work or school, and use pain medication. Survey study, 2021 How common is PMDD among high school girls? About 1 in 20 high school girls (4.89%, or 44 out of 900) had PMDD. The study included girls aged 12-16 in India. Interview study, 2021 How common is PMDD in female university students and what increases the risk? About 21.1% of university students have PMDD. Medical students face higher risk, as do women with heavier periods and certain personality traits like higher anxiety and lower sociability. Survey study, 2021 Does being overweight or not getting enough calcium affect PMS? Being overweight is linked to more severe PMS. Getting enough calcium does not appear to affect PMS severity. Survey study, 2021 Does COVID-19 stress affect menstrual cycle regularity? Women healthcare workers with irregular periods reported significantly higher stress, anxiety, and depression linked to COVID-19 compared to women with regular periods. About 28.7% of the women in the study had irregular cycles during the pandemic. Survey study, 2021 At what age do teenage girls first notice premenstrual symptoms? Most girls first noticed PMS around age 15, about 2 years after their first period. Girls who started their period earlier were slightly less likely to develop PMS later. Systematic review, 2020 Does calcium help with PMS? The evidence so far suggests calcium may be helpful: women with PMS tend to have lower blood calcium, and taking calcium supplements often improved PMS symptoms, but the review authors say stronger studies are still needed. Survey study, 2020 What factors predict which women will develop PMDD symptoms? How much women ruminate or worry about their problems and having a specific type of period pain are linked to PMDD. Stress and drug use were not linked. The researchers were able to predict PMDD symptoms correctly 90% of the time using these factors. Randomised trial, 2020 Does anise reduce PMS symptoms? Yes. Anise significantly decreased PMS symptom intensity compared to placebo over two menstrual cycles. Survey study, 2020 Is period pain common in Polish women and what causes it? Period pain is very common, affecting 94% of Polish women. It's linked to family history, lack of exercise, and low self-esteem, though this is a cross-sectional study so we cannot be sure these things cause it. Systematic review, 2020 Does exercise help reduce premenstrual syndrome? This paper is a plan for a future study, not completed research. Current guidelines recommend exercise as a first-line PMS treatment, but existing evidence remains inconclusive. Systematic review, 2020 Do psychotic symptoms get worse during the menstrual period? Yes. Women with psychotic disorders are 1.48 times more likely to need psychiatric admission during the perimenstrual phase. Some studies also found symptom worsening during this time. Systematic review, 2020 Does having PMS before pregnancy increase the risk of postpartum depression? Yes. Women with a history of PMS before pregnancy are 2.20 times more likely to develop postpartum depression. However, the quality of evidence is low, which limits how confident we can be. Cohort study, 2020 Does having PMS before pregnancy predict postpartum depression? Yes. Women with a history of PMS or PMDD were at higher risk for depression after childbirth, especially if they had previous depression. Case-control study, 2020 What factors predict which teenage girls will have PMS? Stress and a marker in the urine were the strongest predictors of PMS in teenage girls. Diet factors like fat, calcium, and zinc were also related to PMS risk. Survey study, 2020 How common are PMS and PMDD in women? In this study, all 198 women had some premenstrual symptoms, and 3.6% met criteria for PMDD, the more severe form. Survey study, 2020 How many adolescent girls have PMS, and does teaching them about it help? More than 50% of adolescent girls have PMS. Most girls lack knowledge about what PMS is, but educational programs significantly improve their knowledge. Cohort study, 2020 How common are PMS and painful periods in female medical students, and do they affect school attendance? Very common. 68% of the 100 students had PMS and 45% had painful periods. Both conditions were linked to missing classes and to being overweight or physically inactive. Survey study, 2020 Is PMS common in female university students and linked to anxiety, depression, and stress? PMS is common, with most students having moderate symptoms and 8% experiencing severe PMS. PMS is significantly associated with anxiety, depression, and stress. Case-control study, 2020 How does competitive sports affect PMS, PMDD, and menstrual disorders in young female athletes? Female athletes had significantly more PMS (49.33%) than non-athletes (32%), with the risk increasing by 1.71 times per year of age. PMDD rates were similar between groups, but athletes had heavier periods and longer breaks between menstruation. Survey study, 2020 What topics are researchers most interested in studying about PMS and PMDD? Researchers have published 2,833 papers on PMS and PMDD from 1945 to 2018, with growing focus on depression, anxiety, and how these conditions affect young women. Cohort study, 2019 How do exercise, diet and weight affect menstrual problems? Lack of exercise and poor diet are linked to more menstrual symptoms, and higher weight is linked to both PMS and period pain. The evidence is moderate but cannot prove these cause the symptoms. Survey study, 2019 What lifestyle and sleep habits are linked to PMS in teenage girls? In Japanese high school students, poor sleep quality, long internet use, skipping breakfast, and not playing sports were linked to higher PMS risk, with menstrual pain being the strongest risk factor. This is observational so we cannot be sure these habits cause PMS. Survey study, 2019 What menstrual problems do international students develop when they move to China? Almost half of the international students reported menstrual pattern changes after arriving. Premenstrual symptoms were the most common problem, affecting about one in three students. High stress levels were linked to menstrual changes and period pain. Cohort study, 2019 Do young female athletes have more menstrual problems and PMS than non-athletes? Yes. Intense exercise before first menstruation delayed when girls got their period. Competitive sport increased risk of PMS and PMDD. Case-control study, 2019 Do negative thinking patterns increase the risk of PMS or PMDD? Yes. Women with PMS and PMDD have more negative thinking patterns and process information differently than other women, especially during the luteal phase. Review, 2019 How do brain changes during reproductive transitions cause depression in women? A review of brain imaging studies found that depression related to reproductive cycle changes involves different brain activation patterns than typical major depression. Understanding these differences might help develop better treatments, though the causes remain unclear. Interview study, 2019 Which PMDD symptoms are most common in college students? Physical symptoms like pain are most common (91.4%), followed by anger and irritability (84.5%). PMDD causes the biggest problems with family relationships and home responsibilities. About 1 in 10 college students meet PMDD criteria. Survey study, 2019 Does PMS affect quality of life in healthcare workers? Yes, quality of life is significantly reduced in healthcare workers with PMS, especially when symptoms are more severe. Quality of life is also worse in women who are older, work certain job types, are married, or have irregular cycles. Survey study, 2019 How common are PMS and PMDD in adolescent girls, and how much do they affect daily life? 19.3% of girls aged 8-23 had moderate to severe PMS and 4.6% had PMDD.

Older age, painful periods, heavy periods, high stress, and having a mother with PMS all increased risk. Survey study, 2019 What diet and lifestyle factors are linked to PMS in university students? Smoking and eating foods high in calories, fat, sugar, and salt were linked to higher PMS risk among university students in the UAE. This observational study cannot prove these factors cause PMS. Survey study, 2019 How common is PMDD in teenage girls? Nearly 5% of teenage girls surveyed had PMDD. Girls with PMDD also had higher levels of stress, depression, and anxiety. Survey study, 2019 How common are PMS and PMDD in teenage girls? Over half (53.5%) of female high school students experience PMS and about 1 in 8 (12.22%) experience PMDD. Girls with a family history of PMS are more likely to have these conditions. Schools could help by providing education about PMS. Cohort study, 2019 Does insomnia from shift work cause irregular periods? Yes. Nurses with insomnia had 2-3 times higher odds of developing irregular periods compared to those without insomnia. The more severe the insomnia, the higher the risk. Case-control study, 2019 Does weight and body composition affect the risk of PMS? Yes, but in a surprising direction. Women with lower BMI had PMS more often than women with higher BMI. Women with PMS also had more muscle and water and less body fat. Case-control study, 2019 Is smoking linked to higher risk of PMS or PMDD? Yes. Smokers had higher odds of PMS (1.78 times) and PMDD (2.92 times) compared to non-smokers. This association was stronger with higher smoking amounts. Cohort study, 2018 Do women with PMS or period pain use more complementary therapies like vitamins or yoga over time? Yes. Over 7 years, Australian women's use of vitamins, yoga, massage and similar therapies linked to PMS and period problems went up, but this study can't say whether those therapies actually worked. Non-randomised trial, 2018 Does high-dose vitamin D help with PMS and period pain in teenagers? Yes, high-dose vitamin D significantly reduced PMS from 14.9% to 4.8% over 9 weeks. The study also found improvements in painful periods and specific symptoms like backache. Survey study, 2018 Does vitamin D or calcium level affect PMS symptoms and menstrual bleeding? Calcium level is linked to heavier menstrual bleeding and irritability, but vitamin D level does not appear linked to PMS symptoms overall. Cohort study, 2018 How common is PMS in young women and is it related to family history? About 4 in 10 young college women have PMS. Having a mother with menstrual problems does not increase your risk, which suggests family history may be protective. Survey study, 2018 How common is PMS in college women and how much does it affect their studies and social life? PMS is very common. 84.4% of students had PMS, and it seriously interfered with their studies and social activities. Survey study, 2018 What causes irregular periods? About 14.3% of Korean women aged 19-40 have irregular periods. Stress and depressive mood are the main causes, not medical conditions. Stress is the strongest factor. Survey study, 2018 How many university students have menstrual problems, and is stress related to them? 91% of the students studied had some kind of menstrual problem. Stress was clearly linked to worse menstrual problems, including pain, absent periods, and premenstrual symptoms. This is a large study but cannot prove stress causes the problems. Survey study, 2018 Do women who exercise regularly have fewer PMS and period pain symptoms than sedentary women? Yes. Sedentary women had significantly more period pain (82% vs 46%) and more PMS symptoms like depressed mood, fatigue, and difficulty concentrating. Survey study, 2018 How common are premenstrual symptoms in female workers, and does exercise help? Fatigue (24%), backache (21.2%), and abdominal bloating (17.4%) were the most common symptoms. Women who exercised regularly reported significantly fewer backaches, less irritability, depression, and less crying. Survey study, 2017 Does less sleep lead to irregular periods in teenage girls? Yes. Girls who sleep 5 hours or less per night are much more likely to have irregular periods than those who sleep 8 or more hours. Of 801 girls studied, 15% had irregular periods. Case-control study, 2017 What lifestyle factors are linked to premenstrual syndrome in teenage girls? Four lifestyle factors showed clear links to PMS: less exercise, higher body weight, more salty foods, and more sugary foods. Guideline, 2017 How should premenstrual disorders be managed? There is no single best treatment. Treatment options include cognitive behavioral therapy, alternative therapy, antidepressants, ovulation suppression, and diuretics. The choice depends on symptoms, age, family plans, health, and preferences. Survey study, 2017 Does asthma get worse before your period? Some women report asthma that worsens before their period, but research has not proven this happens consistently or identified what causes it. Different studies measured this so differently that no clear conclusion can be drawn. Interview study, 2017 What causes PMDD and what are effective treatments? PMDD affects 3 to 8 percent of women. It is caused by fluctuations in hormones and brain chemicals called neurotransmitters. Treatments include hormone therapy, antidepressants, and psychotherapy. Survey study, 2017 How common is PMDD in young women in Ethiopia and what factors increase risk? 26.8 percent of students had PMDD. Women with irregular periods, menstrual pain, or not using family planning methods were significantly more likely to have it. Survey study, 2017 How common are PMS and PMDD, and how much do they affect women's daily life? About one in five young women have PMS and one in 14 have PMDD. Both cause real problems with work and school productivity. Cohort study, 2017 Do women with PMS experience more sexual difficulties and sexual distress? Women with PMS are significantly more likely to report sexual difficulties and sexual distress. 77.6% of women with PMS had sexual concerns compared to 27.3% of controls, and 51.7% of PMS women had sexual difficulties compared to 24.5% of controls. Cohort study, 2017 How common is PMS in high school students, and what symptoms and problems does it cause? About 3 in 10 of the Thai high school students in this study had PMS, and the most common symptoms were angry outbursts and breast tenderness. PMS was linked to problems with concentration and schoolwork, but not with how they got along with others. Systematic review, 2017 How common is PMS among women in Iran? Very common. Pooling many studies, about 7 in 10 reproductive-age women in Iran had PMS, with the rate highest among high school students. Survey study, 2017 How common is PMDD among Arab women and what factors predict it? About 18.6% of women in the UAE met PMDD criteria. Women with higher education, stressful life events, personal or family mental health problems, and painful periods were more likely to have PMDD. Survey study, 2017 Are mental health problems linked to irregular periods in teenage girls? Yes. Girls with high stress are 1.88 times more likely to have irregular periods, those with depression are 2.01 times more likely, and those receiving counseling are 2.92 times more likely. Survey study, 2017 Do women using hormonal birth control have fewer menstrual symptoms? Most women have menstrual symptoms regardless of birth control use. Women not using hormonal contraception report slightly more symptoms on average (5.9 versus 5.3 symptoms). Survey study, 2017 Does exercise reduce PMS symptoms differently in people with different temperaments? Yes, exercise reduced symptoms in both groups, but the improvement was much greater in people with cold temperament, where all physical and mental symptoms improved significantly. Survey study, 2016 How do women use complementary and alternative medicine for menstrual pain? Many women use it, especially herbal remedies and supplements, usually without a healthcare provider's guidance. Most women think these treatments work, but there is limited scientific evidence about how well they actually do. Survey study, 2016 Do hormonal contraceptives reduce PMS symptoms? Hormonal contraceptives are linked to lower risk of some PMS symptoms, including cramps, fatigue, and depression, but not others like mood swings and bloating. Survey study, 2016 How common are menstrual problems in teenage girls?

Survey study, 2016 How many high school students in Japan miss school due to premenstrual symptoms and what increases the risk? About 1 in 9 girls (11.9%) were absent from school due to premenstrual symptoms. Sleep problems, physical symptoms, reduced social activities, and preference for salty food increased the risk. Survey study, 2016 How common is PMS in nursing and midwifery students, and does smoking affect it? About one in three students (33%) have PMS. Current smokers have much higher rates (52.9%) than never-smokers (28.7%), suggesting smoking is linked to worse PMS.

Women with PMS used complementary medicine practitioners and therapies significantly more often than those without. Study, 2015 Does vitamin B6 help reduce PMS symptoms in teenage girls? Yes. Teenage girls who took vitamin B6 had a greater decrease in PMS symptoms compared to girls who received placebo. Cohort study, 2015 Does using illicit drugs increase the risk of PMS? Yes, women using multiple drugs or starting before age 15 had higher odds of PMS. However, this observational study cannot prove drugs cause PMS. Cohort study, 2015 How common are PMS and PMDD in young female athletes? PMDD affects about 8% of young women regardless of sport. PMS is significantly more common in athletes (49.33%) than non-athletes (32%). Survey study, 2015 How common is PMS and other menstrual problems in teenage girls? Very common. 95% of girls who completed the survey reported some menstrual disorder, and 65% had PMS symptoms. Review, 2015 What causes PMDD? A review suggests that neurosteroids and stress may be key contributors to PMDD. PMDD is characterized by cognitive-affective symptoms in the premenstrual phase and is distinct from other mood disorders. More research is needed to confirm these mechanisms. Cohort study, 2015 What factors predict anxiety and depression during pregnancy and after birth? Women are at high risk for anxiety and depression around pregnancy and birth, especially those with prior mental health problems or poor social support, though symptoms vary widely between women. Survey study, 2015 Is neck and shoulder pain common after birth, and what increases the risk? Yes, 73.1% of women had neck and shoulder pain one month after birth. Women who had previous PMS, anemia during pregnancy, more breastfeeding, and worse mood had higher rates, though this is observational so causation is not proven. Survey study, 2014 How common is PMS in university students and does it affect their quality of life? PMS is common among university students and clearly reduces quality of life in all areas. Interestingly, overweight and obese students had lower rates of PMS than normal-weight students. Survey study, 2014 Are depression and anxiety linked to period pain in teenage girls? Yes. Girls with painful periods had higher anxiety and depression scores than those without. Girls with the most severe form of PMS had much higher scores. Survey study, 2014 How many university students have dysmenorrhea and PMS, and what causes them? 85.1% had dysmenorrhea and 72.8% had PMS. Family history was the strongest risk factor for both. Regular menstrual cycles were protective against dysmenorrhea. Survey study, 2014 Do PMS symptoms differ by race and ethnicity? Yes. Chinese women reported significantly fewer PMS symptoms than Caucasian and African-American women in this study, particularly fewer mood changes and pain. Survey study, 2014 How common are PMDD and PMS? Both are common. PMDD affects 3 to 8 percent of women of childbearing age, while PMS affects 20 to 30 percent. Both significantly reduce quality of life and work productivity. Cohort study, 2014 Is spotting before the period a sign of endometriosis? Yes. Women with premenstrual spotting lasting 2 or more days were much more likely to have endometriosis, making this symptom a strong predictor of the condition. Survey study, 2014 How many Jordanian women have PMS or PMDD, what symptoms are worst, and how do they manage them? About 80% have PMS and 10% have PMDD. The worst symptoms are belly cramps, lower back pain, and chest pain. Women most often use pain medicine, hot drinks, warm clothes, or lie down. Survey study, 2014 How common is premenstrual syndrome in teenage and young adult girls? About 28 percent of girls aged 13 to 22 had some premenstrual syndrome symptoms, and about 7 percent had severe symptoms. Fatigue and backache were the most common. Cohort study, 2014 How common are PMDD, subthreshold PMDD, and PMS in adolescent girls, and how much do they affect their lives? About 20 percent of adolescent girls reported distressing premenstrual symptoms. Roughly 6.76 percent met criteria for full PMDD and 6.2 percent met criteria for subthreshold PMDD, which is a milder form. Cohort study, 2013 How do menstrual cycle phase and hormonal birth control affect sleep? Women on hormonal birth control had better sleep quality and fewer breathing interruptions during sleep compared to women not on birth control. The effect of birth control was stronger than menstrual cycle phase. Survey study, 2013 What causes PMS and PMDD? PMS and PMDD are caused by a complex mix of biological, psychological, and social factors, but this review does not report new research findings. Survey study, 2013 Does having PMS or PMDD increase the risk of postpartum depression? Yes. Women with a history of PMS or PMDD are nearly twice as likely to develop postpartum depression. Survey study, 2013 What increases depression risk in women of reproductive age? Early motherhood, having three or more children, low education, and high premenstrual symptoms increased depression risk. Overall, 32.8% had depression, but only 10.4% received treatment. Cohort study, 2013 Does having PMS or PMDD before pregnancy increase the risk of postpartum depression? Yes. Women with a history of PMS or PMDD were more likely to develop postpartum depression, especially those who had been pregnant before. The link was confirmed at 5 days, 6 weeks, and 6 months after birth. Survey study, 2013 Does more physical activity reduce PMS symptoms? Yes, women who are more physically active have significantly fewer PMS symptoms. The relationship is very clear and statistically significant (p<0.001). Case-control study, 2013 Are migraines linked to menstrual mood disorders and childhood sexual abuse? Migraine with aura is much more common in women with menstrual mood disorders (11 out of 88 versus none out of 86 in controls), and women with both a mood disorder and childhood sexual abuse history have about 12 times higher risk. The study shows association but not cause. Randomised trial, 2013 Do women with depression whose symptoms worsen before their period respond differently to antidepressants? About two-thirds of depressed women report premenstrual worsening, and these women tend to have more chronic depression and medical problems. However, premenstrual worsening does not predict which antidepressants will work. Cohort study, 2012 Does PMS affect how stiff arteries become and blood pressure? Yes, women with PMS showed increased artery stiffness during the later cycle phases and menstruation. Women who reported PMS symptoms before menopause had higher rates of high blood pressure and stiffer arteries after menopause. The study does not prove PMS causes these changes. Survey study, 2012 How common are PMS and PMDD, and how much do they affect women's lives? PMS symptoms are very common in women during reproductive years. PMDD affects 3-8% of women and causes significant reductions in quality of life and daily activities. Survey study, 2012 What menstrual problems are most common in nursing students? Irregular periods and PMS are very common, affecting 80.7% and 54% of students respectively. Many said these problems affected their daily activities and schoolwork. Survey study, 2012 What psychiatric conditions are linked to PMDD in Korean women? About 2.4% of Korean women experience PMDD.

Survey study, 2012 How common are PMS and severe PMS in Chinese women, and what are the typical symptoms? In Chinese women, PMS affects 21.1% and severe PMS affects 2.1%. The most common symptoms are irritability, breast tenderness, depression, abdominal bloating, and angry outbursts. Survey study, 2011 How common are period pain and PMS in Korean teenage girls? Very common. 82% of girls experienced painful periods and 58.8% experienced PMS symptoms. Most girls didn't seek medical help. Cohort study, 2011 Do Spanish women seek medical advice for premenstrual symptoms? About three-quarters of Spanish women experience premenstrual symptoms, but only 18.7% seek medical advice. Most did not seek help because they thought symptoms were normal. Case-control study, 2011 Does eating more B vitamins help prevent PMS? Women eating more riboflavin and thiamine from food had lower PMS risk, but B vitamin pills did not help. Survey study, 2011 How do premenstrual symptoms change as women age, and what factors influence them? Premenstrual symptoms follow different patterns as women age: some stay the same, some decrease, some peak around age 35, and others peak around age 40-44. Smoking is linked to more symptoms, and having more pregnancies is linked to fewer symptoms. Survey study, 2011 Do Black women and white women have different rates of PMDD? Black women were less likely to have PMDD than white women (2.9% versus 4.4%), even after accounting for smoking, weight, income, depression, and many other factors. The reason for this difference is not yet clear. Survey study, 2011 How common are premenstrual symptoms in Pakistani women and how much do they affect daily life? Premenstrual symptoms are very common, with 5.5% to 79.9% diagnosed depending on the classification system used. 98.8% of women were unaware they had a recognized condition. More severe symptoms strongly predicted whether women sought medical help. Survey study, 2011 How common is PMS in working women, and do they know about it? Between 38% and 74% of working women have PMS depending on which diagnostic criteria are used. Most women did not know what PMS was and rarely saw doctors about it. Survey study, 2011 How common is premenstrual syndrome in Turkish college students and how does it affect quality of life? Premenstrual syndrome was found in 72.1% of college students and was strongly associated with significantly reduced quality of life. Survey study, 2011 How common is premenstrual syndrome in Sri Lankan adolescent schoolgirls and how does it affect them? About 8.75% of Sri Lankan adolescent schoolgirls have premenstrual syndrome. It significantly interferes with school activities, relationships, and daily routines. Cohort study, 2011 How common are premenstrual syndrome and PMDD in Spanish women? Most Spanish women (73.7%) experience some premenstrual symptoms, but only 8.9% have moderate or severe PMS and 1.1% meet criteria for PMDD. Survey study, 2011 Is premenstrual syndrome inherited? Yes. Genes control about 95% of PMS risk while environment controls only 5%. Identical twins are much more likely to both have PMS (81% match) than fraternal twins (67% match), showing a strong genetic effect. Survey study, 2010 What premenstrual symptoms do Asian women experience most? The most common symptoms are joint, muscle and back pain, cramps, abdominal pain, and breast tenderness. How severe the symptoms are directly matches how many months per year a woman is affected (correlation 0.85). Case-control study, 2010 Does body weight affect the risk of developing PMS? Yes. Higher body mass index (BMI) is associated with increased PMS risk. Each 1 kg/m² increase in BMI was linked to a 3% increase in PMS risk. Cohort study, 2010 Which lifestyle factors and contraceptive methods are linked to premenstrual symptoms? About 1 in 4 women had premenstrual symptoms. Women with higher education and less stress had fewer symptoms. Hormonal birth control was linked with fewer symptoms. Cohort study, 2010 Does asthma or airway reactivity change around menstruation? Yes. Airway reactivity significantly increased in the days around menstruation in women not taking birth control (odds ratio 2.3), but birth control pills appeared protective and prevented this increase. Survey study, 2010 How many teenage girls in Japan have PMS or PMDD? 64.6% of Japanese high school girls reported premenstrual symptoms. While this was lower than in adult women, the rate of moderate-to-severe PMS and PMDD was actually higher in teenagers, and symptoms significantly affected their daily activities. Cohort study, 2010 What factors affect the risk of getting PMDD? In a large Polish study, only women's educational level significantly reduced PMDD risk. Most other reproductive and lifestyle factors tested did not show a significant effect. Survey study, 2010 How much does PMS affect the daily lives of Korean women? PMS is extremely common in Korean women, with 32% meeting clinical criteria for PMS, and it significantly disrupts daily activities. However, almost none of the women knew what PMS or PMDD was or sought medical help for it. Interview study, 2010 How common is PMS in young Saudi women and what factors increase risk? 35.6% of female medical students in Saudi Arabia were diagnosed with PMS. Risk factors included being older, living in a rural area, having a family history of PMS, and starting periods at a younger age. Survey study, 2009 How many women in Switzerland have PMS or PMDD, and what factors are connected to them? About 10% of Swiss women of reproductive age meet criteria for PMS and 3% meet criteria for PMDD. Both are more common in women aged 35-44, women not working, and women with poor physical or mental health. Survey study, 2009 What premenstrual symptoms do Nigerian university women have and what factors are linked to them? About half of Nigerian university women had premenstrual symptoms at rates similar to Western countries, with breast tenderness being the most common symptom. Cohort study, 2009 How common is PMS in French women and how stable is it over time? 12.2% of French women reported PMS symptoms that affected their daily lives. PMS status fluctuated significantly over a year, with 72% of women with PMS showing changes. Case-control study, 2009 How common is irritable bowel syndrome in Korean teenage girls and what causes it? One in four Korean teenage girls has IBS. Stress, anxiety, and depression were strongly linked to IBS, with depression showing the strongest connection. Survey study, 2009 How common is PMS in young Iranian women? PMS is very common: almost all young women have at least one PMS symptom, and 16% have clinically significant PMS. Younger women aged 18-20 have more severe symptoms than slightly older women. Survey study, 2009 How common is PMDD among American women? Only 1.3% of women met full PMDD criteria using strict diagnostic rules. This is much lower than previous research suggested. Case-control study, 2009 Does alcohol use increase the risk of developing PMS or PMDD? Alcohol use is not strongly linked to developing PMS or PMDD. Starting to drink before age 18 or long-term drinking may minimally increase risk, but the increases are small. Survey study, 2008 Can we measure how much premenstrual symptoms affect a woman's quality of life? Yes. Researchers developed a brief 6-item survey that accurately identifies women with significant PMS or PMDD and measures its impact on daily life. Survey study, 2008 Can a simple checklist help identify menstrual migraine? Yes. A 3-question tool works well at identifying menstrual migraine in women at gynecology clinics. Cohort study, 2008 How common is PMS in medical students and how much does it affect their quality of life? 51% of medical students had PMS, with 5.8% having severe PMDD. PMS significantly impaired their mental and physical quality of life and academic performance. Cohort study, 2008 Does age at menarche affect how much premenstrual symptoms women have? Women who started their period before age 11 reported more symptoms and syndrome, but the difference was not strong enough to be certain it wasn't just chance. Randomised trial, 2008 How common are PMS and PMDD in teenage girls? At least 20% of adolescents have moderate-to-severe premenstrual symptoms that interfere with daily life. However, large research studies focused on teenagers have not been done, so exact numbers and the best treatments are not well understood. Survey study, 2008 What factors are linked to PMS in Thai nurses? Coffee consumption and having a negative attitude toward menstruation are the strongest factors linked to PMS in this group. 25.1% of Thai nurses have PMS. Cohort study, 2008 Do women with autism have PMS more often than women without autism? Yes, women with autism had much higher rates of PMS compared to women without autism. In the autism group, 92% showed PMS symptoms, while only 11% of the control group did. Cohort study, 2008 Do headaches, irritability, and mood swings get worse or better during the transition to menopause? Surprisingly, these symptoms improve. Headaches decrease, and irritability and mood swings decline as women approach menopause, though these improvements are linked to hormone shifts and especially to a woman's PMS history and current stress. Case-control study, 2007 What environmental and hormonal factors affect asthma severity in women? Body weight and hormonal changes around the menstrual cycle are associated with asthma severity in women. Smoking and occupational exposures also increase severity. Case-control study, 2007 Is history of adolescent abuse associated with PMS in adulthood? Yes. Women who experienced physical or sexual abuse in adolescence had significantly more PMS in adulthood, and their symptoms were more severe with more depression and mood problems. Cohort study, 2007 Does stress affect menstrual regularity? Yes. Women with histories of trauma or parental substance abuse were more likely to have irregular periods or missed periods. Survey study, 2007 How common is severe PMS and what are the most common symptoms? Severe PMS affects about 6.1% of women. The most frequent symptoms are irritability and anxiety, and most women with severe PMS have significant life disruption. Cohort study, 2006 Does the hormone change at menopause cause depressed mood in women who have never been depressed before? Yes. In this study women with no history of depression were much more likely to have high depression scores and diagnosed depressive disorders during the menopause transition, and this was linked to changing hormone levels, not just age. Survey study, 2006 How common is premenstrual syndrome and what factors put women at higher risk? About 25% of women have PMS by objective measure, though 60% report having it. Younger, more educated, economically better-off women and those not using contraceptives had higher rates. Survey study, 2006 How common is PMS in teenage girls in the UAE and how much does it affect them? PMS affects 16.4% of teenage schoolgirls in the UAE and seriously impacts their school performance, social interactions, and emotional wellbeing. Cohort study, 2006 What increases the risk of depression in the first days after childbirth? A history of mental illness, PMDD, and mood symptoms during late pregnancy all increase the risk of early postpartum depression, though only 6.8% of women developed symptoms. Randomised trial, 2005 Which birth control pill reduces PMS symptoms better: drospirenone or levonorgestrel? Drospirenone-containing pills reduced PMS symptoms more effectively than levonorgestrel pills after six cycles, especially mood symptoms and water retention. Case-control study, 2005 Does eating more calcium and vitamin D help prevent PMS? Yes. Women eating the most vitamin D and calcium had lower PMS risk, and drinking more low-fat milk was also linked to lower risk. Cohort study, 2005 Is PMDD a strong risk factor for postpartum depression? Yes, women with PMDD have a 9.3-fold higher risk of major postpartum depression than women without PMDD. Cohort study, 2005 Do women with PMDD have depression symptoms outside the luteal phase? Yes. Even women with minor or moderate depression symptoms when not premenstrual were about 1.9 times more likely to have PMDD, suggesting PMDD is a variant of depression that becomes worse premenstrually rather than appearing only premenstrually. Case-control study, 2004 Do menstrual characteristics and pregnancy history predict depression risk? Yes, earlier age at first period, heavier periods, and irregular periods in early menstruation predicted higher depression risk. Women with multiple miscarriages or abortions had 2-3 times higher depression risk. Survey study, 2004 How often does depression get worse before a woman's period? Depressed women had 1.34 more symptoms that got worse before their period compared to other times. Older women were more likely to experience worsening symptoms. Cohort study, 2004 What risk factors cause PMDD to develop? Traumatic events, anxiety disorders, and high daily stress significantly increase the risk of developing PMDD. Women who already had subthreshold PMDD at the start were at highest risk. Study, 2003 Can a specific birth control pill help with PMS symptoms? Yes. In this study, 80% of women taking a pill containing drospirenone and ethinylestradiol reported improvement, and 75% said they were satisfied with the treatment. Review, 2003 Does bipolar disorder affect women differently than men? Yes. Bipolar disorder often starts later in women, who experience more depressive episodes and rapid mood cycling. The postpartum period is high-risk for onset or recurrence. Case-control study, 2003 Does birth control pill use improve or worsen premenstrual mood? The pill doesn't affect mood in most women. Mood is most likely to worsen in women with a history of depression, and most likely to improve in women with early-onset premenstrual symptoms or painful periods. Survey study, 2003 Does migraine risk change during menopause in women with PMS? Yes. In women with PMS, migraine is highest in late perimenopause at 31% and lowest after menopause at 7%. Hormone levels also affect migraine risk. Cohort study, 2003 Do symptoms change across the menstrual cycle and does birth control affect this? Symptoms are lowest in the early cycle phase and increase before and during menstruation. Over 40 percent of women show a 30 percent increase in symptoms before their period. Birth control use does not change whether women experience these changes. Survey study, 2003 How many women have PMDD and how serious is it? 3-8 percent of women meet strict PMDD criteria, but 13-18 percent experience severe symptoms that disrupt daily life. The impact on quality of life is as serious as major depression. Case-control study, 2002 Does mercury exposure at work affect period pain and menstrual symptoms? Yes, women exposed to mercury vapor at work have significantly higher rates of period pain and cramping. Since this is observational research, it shows association but not definite causation. Cohort study, 2002 How much do genes versus environment contribute to PMS symptoms? Genes accounted for 44% of PMS symptom differences. Genes for PMS overlap with genes for neuroticism and depression but 39% of PMS genetic variance is independent of these traits. Cohort study, 2002 How common is PMDD in midlife women, and what raises the risk? In this large community study, about 6.4% of women who tracked symptoms daily actually met the criteria for PMDD. Lower education, a past history of major depression, and current smoking were linked to higher odds of PMDD, while not working outside the home was linked to lower odds. Cohort study, 2002 How common is PMDD and does it stick around? PMDD affects 5.8% of young women and tends to persist. Most women with PMDD also have anxiety or other mental health conditions, use healthcare more, and have higher suicide rates. Review, 2002 What are the reproductive-related mood disorders and how are they connected? Mood and anxiety disorders are more common in women around menstruation, after childbirth, and during perimenopause. They all appear linked to changes in ovarian hormones. Survey study, 2001 What behaviors and factors are linked to breast pain during the menstrual cycle? Smoking, caffeine consumption, and stress are each associated with more breast pain. Birth control pills are associated with less breast pain and PMS. Case-control study, 2001 Do women with seasonal depression have PMDD more often than other women? Yes. Women with seasonal depression are much more likely to have PMDD - 46 percent versus 2 percent in a healthy control group (P<0.001). Cohort study, 2001 How common are premenstrual mood symptoms like irritability and tension in women? In this community study, about 1 in 5 women had moderate or severe perimenstrual psychological symptoms, and irritability, nervousness and tension stood out as the core symptoms, whether or not depressed mood was also present. Cohort study, 2000 What causes irregular periods in women with bulimia, and do they improve with treatment? Irregular periods in bulimia were linked to vomiting, low thyroid hormone, and low dietary fat. After 12 months of treatment, 56.8 percent of women with irregular cycles became regular. This study concerns eating disorders, not PMS or PMDD. Cohort study, 2000 How many women in a regular population experience menstrual cycle-related symptom changes? About 45% of women experience symptom changes between menstrual phases. However, the patterns vary widely. About 27% have patterns opposite to typical PMS symptoms. Daily tracking is necessary to know what actually happens for each person. Cohort study, 2000 How common are symptom changes across the menstrual cycle and PMDD? Symptom changes during the menstrual cycle are very common, with 80.7% of women showing such changes. Among those who self-identified with PMS (51%), only 2-6% met clinical criteria for PMDD. Survey study, 2000 How common are mental health conditions in women seeing gynecology doctors? One in five women visiting a gynecology clinic have a current mental health condition. A screening questionnaire helps doctors identify these conditions, but it rarely leads to actual treatment. Survey study, 1999 What lifestyle and personal factors are linked to PMS? Stress and alcohol use are strongly linked to PMS. Younger women and those with longer periods are more likely to have PMS. Women with PMS were more likely to exercise regularly. Survey study, 1999 How common are menstrual problems in teenage girls and do they relate to early puberty? Menstrual pain was very common (69.60%), and over half the girls (51.20%) had PMS symptoms. Girls who started menstruating earlier experienced significantly more menstrual pain. Cohort study, 1999 How common are depression symptoms in women in their late 30s and early 40s, and what predicts them? About 22% of women aged 36-44 showed depression symptoms. Marital status, smoking, and having children predicted depression risk more than menstrual cycle changes alone. Survey study, 1998 How common is PMS and what treatments do women use? 41% of US women said they had PMS, and an additional 17% experienced PMS symptoms without labeling them as PMS. Of those with symptoms, 42% used medication, mostly over-the-counter drugs; most who tried complementary therapy like exercise found it helpful. Cohort study, 1998 Are premenstrual symptoms inherited, and are they related to major depression? About 56% of stable premenstrual symptoms appear to be inherited. The genetic factors for depression and premenstrual symptoms are mostly separate and not closely related. Study, 1997 Does the time of the menstrual cycle affect how women answer questions about mood? No. Women's answers about mood symptoms are just as reliable and consistent regardless of where they are in their menstrual cycle. All women scored higher than men overall, but cycle phase didn't change this. Survey study, 1997 How common is breast pain before your period and does it affect daily life? Very common. 69% of women get premenstrual breast discomfort and 11% have moderate-to-severe pain. It affects sexual activity in 48% of women. Survey study, 1996 Do women who had severe PMS get more hot flushes in menopause? Yes. About 49% of women with moderate to severe hot flushes had previously experienced moderate to severe PMS, compared to only 24% of women with little or no hot flushes. Women with hot flushes were also more likely to report their mothers had them. Case-control study, 1996 What is linked to hot flushes during midlife and menopause? Hot flushes are linked to higher FSH levels, lower estradiol, and a history of premenstrual complaints. They become increasingly common as women approach and pass their final menstrual period. Survey study, 1996 How common is infertility in older women and what conditions are linked to it? Permanent infertility affects 2.6% of women aged 40-42, and subfertility affects 7.7%. Premenstrual tension is more common in infertile women (almost 40%) than in fertile women (29.4%). Cohort study, 1995 Do working conditions affect PMS symptoms? Yes. A study of 539 hospital workers found that physical demands like lifting and work stress were associated with worse perimenstrual symptoms including pain and swelling. Randomised trial, 1994 Does alprazolam help women with late luteal phase dysphoric disorder? Yes, but only for women whose symptoms happen only in the luteal phase. It reduced tension, irritability, and anxiety in that group but not in women who also had anxiety or depression at other times of the month. Survey study, 1993 How common are period-related symptoms in Italian women, and do they differ from American women? Period-related symptoms are common in Italian women, occurring most often during the menstrual phase. Italian women reported more symptoms overall than American women, though the difference was smaller for premenstrual symptoms. Cohort study, 1993 When are new mothers most likely to get depression - right after birth or later? Depression peaked at 10 weeks after birth, not immediately afterward. PMS before pregnancy was only linked to postpartum depression once women's periods restarted. Survey study, 1993 Are women with menopause distress more likely to have had past depression linked to their periods? Yes, clearly. Women with high distress at menopause were much more likely to report past depression, needing antidepressant treatment, distress from birth control, PMS symptoms, baby blues, and postpartum depression. Study, 1992 Do women trying to get pregnant report more premenstrual symptoms? Yes. Women in fertility treatment reported more premenstrual symptoms than medical students, and over half of them met criteria for severe premenstrual disorder compared to 42% of students. Case-control study, 1992 Do non-migraine headaches change across the menstrual cycle in women with PMS? Yes. Women with PMS have significantly more non-migraine headaches during the perimenstrual phase (around their period) and more severe headaches than women without PMS. Cohort study, 1992 How common is premenstrual syndrome in teenagers and what predicts who develops it? About 14% of 15-year-old girls had PMS. It was associated with current anxiety, inattention, and poor overall health, but childhood health was not predictive. Study, 1991 Does exposure to DES before birth affect period symptoms in adult women? Mostly no. Women exposed to DES in the womb reported similar period symptoms to unexposed women. The only possible difference was slightly more water retention symptoms in the exposed group. Cohort study, 1991 Do seizures increase during the premenstrual period in women with epilepsy? Yes. A study of 80 women with epilepsy found significantly more seizures in the premenstrual period (p<0.001) compared to other times of the cycle. Case-control study, 1991 How common are premenstrual symptoms in teenage girls, and what factors affect them? 80% of teenage girls had at least one premenstrual symptom, with 25% experiencing pain that severely interfered with daily activities. Symptoms varied by ethnic background and smoking. Cohort study, 1991 Does tubal sterilization cause premenstrual syndrome? No. A study of 78 women with PMS found no difference in symptom severity or hormone levels between those who had tubal sterilization and those who didn't, suggesting PMS is probably not caused by the procedure. Survey study, 1990 Does drinking caffeine make premenstrual syndrome worse? Yes. The more caffeine a woman drinks, the more likely she is to have premenstrual symptoms. Women drinking 8 to 10 cups a day were about 7 times more likely to have severe symptoms than those drinking very little. Cohort study, 1990 What is the prevalence of late luteal phase dysphoric disorder in young university women? 4.6% of young university women met diagnostic criteria. Women in the general population with the disorder reported significantly fewer symptoms than those seeking medical treatment. Study, 1990 Do women with PMS experience more physical symptoms at different times of their cycle? Yes. Women with PMS had noticeable physical symptom swings in 81.2% of their cycles compared to 33.0% in women without PMS. In the premenstrual phase, 80.5% of PMS cycles showed significant symptoms versus 24.0% in non-PMS women. Survey study, 1990 What do we know about what causes PMS and how common it is? A literature review found PMS affects 30 to 40% of women, especially those who work outside the home, have had multiple children, or use alcohol. Many theories about causes exist, but none are proven. Survey study, 1989 What kinds of PMS symptoms tend to occur together? PMS symptoms cluster into two groups: mood and behavior symptoms (which are most common) and physical and thinking symptoms (which are less common). These groups stay the same throughout the entire menstrual cycle. Cohort study, 1989 Does the menstrual cycle affect depression test scores? Yes. Women scored higher on depression tests premenstrually than postmenstrually, and more women met the threshold for depression before their period. However, this may reflect how the test itself changes with the cycle, not actual changes in depression. Case-control study, 1989 Do mood swings only happen to women with PMS, or do other women get them too? Both groups had mood swings, but in women with PMS the low mood clustered tightly in the premenstrual days, while in women without PMS mood changes popped up at random times across the cycle, not just before periods. Survey study, 1988 Do depressive symptoms cluster into patterns including a premenstrual syndrome pattern? Yes. Statistical analysis identified five symptom patterns: one matching major depression and another in younger women as premenstrual syndrome. This explains the gap between reported depression symptoms and diagnoses. Study, 1988 Are there different types of premenstrual symptoms? Yes. Research found three main patterns of premenstrual changes: hostile-depressive, atypical depressive, and anxious, as well as two less common patterns. Study, 1986 What are the different patterns of symptoms before menstruation? The study found five different patterns of premenstrual symptom changes among women. These patterns relate differently to whether women have a history of mood disorders. Survey study, 1986 How common are premenstrual symptoms in women? Very common. About 70% of women reported mental symptoms in combination with body swelling. Premenstrual anxiety increased with age. Cohort study, 1985 Do mood and physical symptoms really change across the menstrual cycle, and does anxiety make this worse? Yes, women reported more symptoms before and during their period and fewer in the days after, though the exact pattern differed a lot between women. Anxious women reported more symptoms overall, but anxiety did not explain the cyclical ups and downs themselves. Randomised trial, 1984 Does vitamin E help premenstrual syndrome symptoms? Yes. Vitamin E significantly improved symptoms in three of the four classes of PMS, though it did not change hormone levels directly. Survey study, 1982 How common are premenstrual symptoms in American women, and what factors affect them?

Survey study, 2026 Why do some women's moods react strongly to hormone changes across the cycle while others don't? This review explains that 'hormone sensitivity' is not one single thing but many, and that while most women are not strongly affected by hormone swings, some are much more sensitive, especially those with existing mood disorders; the exact reasons are still being studied. Survey study, 2026 Why is understanding PMS awareness in teenage girls important? PMS is under-recognized in adolescents and many teenage girls have knowledge gaps about it. Better awareness and education could help young women recognize and manage symptoms earlier. Survey study, 2026 Is PMS linked to body size and how much time women spend sitting? Yes. Women with higher PMS severity had larger waist circumference, higher waist-to-hip ratio, and spent more time being sedentary, especially on weekends. Survey study, 2026 Does low calcium intake relate to PMS in teenage girls? Girls with low calcium intake were more likely to have PMS and period pain. However, we cannot prove that eating more calcium would reduce PMS based on this snapshot study. Systematic review, 2026 How are doctors and researchers diagnosing PMDD differently, and what factors are they using? PMDD is diagnosed inconsistently across research and clinical settings, with some methods relying on patient memory and others on daily tracking. This variation contributes to underdiagnosis and makes research findings harder to compare. Non-randomised trial, 2026 Can ginger tea help reduce PMS symptoms in teenage girls? In this small study, drinking ginger decoction before periods was linked to a significant drop in PMS severity, but the study did not compare against a separate control group getting no treatment, so the result is not fully certain.

Interview study, 2021 What do Spanish women think about their healthcare for premenstrual discomfort? Women feel healthcare is inadequate because doctors only provide medication without investigating underlying causes. They want providers to address root causes and prefer education over medication alone. Survey study, 2021 Do women who sweat excessively have higher rates of PMS? Yes. Women with excessive palmar sweating were 1.276 times as likely to develop PMS as women without excessive sweating. The study suggests a link through the nervous system.

Randomised trial, 2021 Do women with depression or bipolar disorder experience worse symptoms before or during their menstrual cycle? About 60% of women with mood disorders report premenstrual worsening of symptoms, which predicts worse disease overall. Current PMDD treatments work less well or not at all for this problem, and more research is needed to understand what helps. Survey study, 2021 How common is PMS in teenage girls, and what raises the risk? Around 1 in 3 adolescent girls in this Indian study had PMS, and risk was higher with older age, certain education levels, educated or working mothers, and irregular periods.

More stress and less activity were linked to more symptoms. Survey study, 2020 What factors are linked to PMS in young women? Stress, diet, and exercise were linked to PMS. Age of first period and body weight were not linked in this village study. Survey study, 2020 How common are PMS and period pain in college women, and do they affect school work? Both are very common. Over half of women with these conditions had worse school performance, but very few sought medical help. Survey study, 2020 Does diet and carbohydrate intake affect PMS symptoms? Yes, girls with poor diet and low carbohydrate intake had more PMS symptoms in this study. But this does not prove diet causes PMS. Survey study, 2019 Are PMS symptoms linked to how women feel about their health and stress? Yes. Women who reported feeling unhealthy or stressed had much more severe PMS symptoms. How a woman perceives her own health was the strongest factor linked to PMS symptom severity. Survey study, 2019 Is PMS more common in later years of medical school? PMS was found in 39% of female medical students, and it became more common as students progressed through their studies, with final-year students having the highest rates.

This summarizes international guidelines but doesn't show strong evidence about which approach works best. Survey study, 2019 What helps improve quality of life for teenagers with menstrual problems? Exercise, TENS therapy, medication, and counseling all help. Family support and age also matter. Multiple approaches work, not just medication. Non-randomised trial, 2019 Does eating avocado reduce PMS symptoms? Yes. PMS symptom scores dropped significantly when first-year students ate avocado, from an average of 18.20 to 14.13. Survey study, 2019 How common is PMDD in female health science students and what factors cause it? 66.9% had PMDD. The severity of period pain was the main associated factor: those with severe pain were much more likely to have PMDD than those with mild pain. Interview study, 2019 How does PMDD affect adolescents' lives? PMDD causes discomfort and interferes with social relationships in teenagers. Symptoms cycle with the menstrual cycle and are triggered by environmental and hormonal factors. This very small qualitative study (6 students) cannot be generalized. Survey study, 2019 How common is PMDD in Russian women and what increases the risk? About 1 in 6 Russian women have PMDD. Risk is higher in women aged 15-24 and those with family history of psychiatric disease. Survey study, 2019 Who is most likely to have PMS among school students? Most school students (81.3%) reported PMS. Older age and heavy non-academic duties increased the likelihood, while longer menstrual cycles decreased it. Survey study, 2019 Does stress from studying medicine make PMS worse? Medical students had higher PMS scores than non-medical students (93.791 vs 88.473), suggesting stress may worsen PMS. Both groups scored above the PMS threshold. Without a control group, we cannot be certain stress is the cause. Survey study, 2019 Does how much exercise a university student does affect whether she gets PMS? No. Over 6 in 10 students had PMS, but their activity level and whether they exercised regularly made no measurable difference to their PMS. Cohort study, 2019 How common is PMS in female students, and how does it affect their daily activities?

PMS was linked to heavier periods, worse period pain, and less physical activity. Survey study, 2019 Does PMS affect medicine students and literature students differently? Yes. Literature students experienced more PMS and more severe symptoms than medicine students, and PMS had a bigger impact on their daily life and academic work. Survey study, 2019 Is premenstrual syndrome a risk factor for sexual dysfunction? No. This study of 282 women found no significant relationship between PMS and sexual dysfunction. Age and urinary problems increased sexual dysfunction risk instead. Survey study, 2019 How common is PMS in female university students, and does it affect mental well-being? PMS was very common in this group of students, and worse PMS symptoms were linked to lower psychological well-being, though PMS only explained a small part of that well-being. Survey study, 2019 How common is premenstrual syndrome in women of reproductive age? Very common. This study of 133 female nursing students found all had mild to moderate PMS symptoms, with a mean score of 99.62. However, results may not apply to all women since participants were only nursing students. Survey study, 2019 How common is premenstrual syndrome in female university students and how much does it affect them? About 1 in 5 female students (18%) had PMS. Among those with PMS, 75% had stopped studying, showing how severe it can be. Survey study, 2019 How common is PMS among college students and does it affect their quality of life? PMS affects 62.7% of college students studied and reduces quality of life across physical, mental, social, and environmental domains. Survey study, 2019 How common are PMS and PMDD in college girls? About 14.3% of college girls in this study had moderate to severe PMS and 3.7% had PMDD. We cannot be very confident these figures apply elsewhere because this is a cross-sectional survey from one city. Survey study, 2019 How common are PMS and PMDD in high school students? 42.5% of teenage girls had PMS symptoms and 23.6% had PMDD symptoms. The study was cross-sectional, so these figures show how common the conditions were at one point in time rather than proving how the conditions develop. Cohort study, 2019 Is there a link between menstrual symptoms and anxiety, depression, and stress in teenage girls? Yes. There was a strong correlation between menstrual distress and depression, anxiety, and stress, with distress significantly higher before, during, and after menstruation (p=0.000). Case-control study, 2019 Are zinc and copper levels linked to PMS in teenage girls? The study found that girls with both irritable bowel syndrome and period pain had lower dietary zinc intake, but did not find a clear link between minerals and PMS alone. Survey study, 2019 How common is PMS in female operating room technologists? The study aimed to find how common PMS is in female operating room technologists and what factors influence it, but the results are not provided in this abstract.

Adolescents had two different views of PMDD. Some saw it as a natural part of being female, while others saw it as a disease. The study included only 6 girls, so findings may not apply to all teenagers. Survey study, 2018 How common is PMS among female university students in Nigeria? Very common. In this study, 42.9% of students met the criteria for PMS, and almost half of those (47.6%) had severe PMS or PMDD. Survey study, 2018 How aware are men of what PMS is and how it affects their partners? This abstract only describes the background and purpose of the study; it does not give the actual results on men's awareness, attitude, or behavior regarding PMS. Survey study, 2018 Can a questionnaire predict which homeopathic medicine helps PMS? Yes, a questionnaire with a computer algorithm reliably ranked 11 homeopathic medicines for PMS based on a woman's specific symptoms, though this does not prove the medicines actually work. Survey study, 2018 How do women respond differently to psychiatric medications and why do we need sex-specific treatments? Women respond differently to psychiatric medications than men because of biological differences in brain receptors and hormones. Sex-specific treatments are important for conditions like PMDD and postpartum depression. Survey study, 2018 Does exercise change how the brain responds to sad emotions in women with severe PMS? Yes, in women with more severe PMS only. A single aerobic exercise session caused measurable changes in brain wave activity when viewing sad faces, especially in areas that process emotions. Survey study, 2018 Does equol production status affect PMS symptoms in female athletes? Women who couldn't produce equol from soy were 3.34 times more likely to have poor athletic performance from PMS symptoms. But this is a small study in Japanese athletes only, so results may not apply widely. Survey study, 2018 How common is PMS in young women and how much does it affect their lives? PMS affected 47 percent of young medical students and significantly disrupted their academic performance, daily activities, and sleep. Breast tenderness and irritability were the most common symptoms. Survey study, 2018 Do women with PMS sleep differently than women without PMS? Yes. Women with PMS had worse sleep quality, more unrefreshing sleep, more insomnia symptoms, and lower oxygen levels during sleep. The study couldn't explain why. Survey study, 2018 How aware are female students about PMS and PMDD, and do they seek treatment? Most female students (96.4%) knew about PMS but only 19% knew about PMDD, and nearly half did not take treatment for their symptoms. These numbers reliably describe this student group. Survey study, 2018 How common are PMS and PMDD in female university students, and do they affect academic performance? PMS was very common at 92.3% and PMDD was 7.7%. PMDD symptoms negatively affected academic performance. But the study doesn't measure how much the impact is.

PMDD affected 17.6% of young adult women studied in Brazil and was more common in older women and those with lower income. The study relied on women remembering past symptoms, so the actual rate may differ. Survey study, 2018 How common are painful periods and PMS in teenage and young adult girls? Both painful periods (92%) and PMS (86.3%) were very common and strongly linked. These numbers come from a large population-based study of girls in one Egyptian city. Survey study, 2018 How common is PMDD in women with psychiatric disorders? PMDD was far more common in women with psychiatric conditions than controls, especially among those with depression. The findings suggest PMDD is closely related to mental health conditions, particularly depression and bipolar disorder. Survey study, 2018 How common is PMS and does blood pressure change during the menstrual cycle? PMS is very common: 89% of these university students experienced at least one PMS symptom per cycle. Blood pressure was significantly higher during the luteal phase than the follicular phase. Survey study, 2018 How common are PMS and PMDD among medical students and do they affect school and social life?

Survey study, 2018 What is the prevalence of PMDD and severity of PMS among female college students in India? About 4% of female college students had PMDD, and nearly a quarter experienced severe mood swings. Healthcare students had higher rates of moderate to severe symptoms than non-healthcare students. Survey study, 2018 Are certain personality types more likely to have PMS? Yes. Women with higher neuroticism, lower extraversion, lower conscientiousness, and more negative mood were more likely to have PMS. But we can't prove personality causes PMS. Survey study, 2018 How many women actually have PMS when carefully tracked? When women remembered their symptoms from the last three cycles, 62.57% reported three or more symptoms. When carefully tracked with daily diaries, only 4.05% actually met criteria for PMS. Survey study, 2018 Does stress affect premenstrual syndrome? Higher stress levels were linked to premenstrual syndrome in this small study. The findings suggest managing stress might help prevent or reduce symptoms, though larger studies are needed. Interview study, 2017 How common and severe are premenstrual symptoms in young medical and nursing students? Premenstrual symptoms were extremely common, affecting 97.10% of students, and 76.83% met the criteria for PMS, but for most of them the symptoms were mild.

Most adolescent girls have some PMS: more than half (55%) have moderate symptoms and 19% have severe symptoms. Survey study, 2017 Is weight linked to PMS in adolescent girls? Yes, girls with healthier weight had lower PMS rates (64%) compared to overweight girls (94.1%), underweight girls (81.4%), or obese girls (91.7%). But this only shows a link, not that weight causes PMS. Case report, 2017 Does Ayurvedic medicine help PMS? Yes. One 18-year-old woman's mood swings, irritability, and concentration problems were completely relieved after one month of Ayurvedic herbs and weekly therapy sessions. Randomised trial, 2017 What do we currently know about PMDD? PMDD is increasingly recognized as a serious diagnosis affecting 3-8% of women. We understand its symptoms and how to diagnose it, but we don't yet have enough high-quality research to recommend evidence-based treatments. Non-randomised trial, 2017 What are the different types of PMDD according to traditional Chinese medicine? The study identified two types of PMDD based on traditional Chinese medicine principles. Evidence is weak because the study did not use a randomized design. Survey study, 2017 Does malaria infection worsen PMS symptoms? This was the first study to examine whether malaria parasites affect PMS. It found that students with PMS and malaria parasites had lower red blood cell levels, but it cannot prove parasites cause worse PMS. Survey study, 2017 Does physical activity reduce PMS symptoms? Physical activity did not reduce how often women had PMS. However, it did reduce the severity of anxiety, anger, migraines, and abdominal bloating. The study cannot prove activity caused this because it was cross-sectional. Randomised trial, 2017 Does having PMS or PMDD affect how well university students do academically? No. Academic performance did not differ between students with different levels of PMS or PMDD. However, the length of the menstrual cycle was significantly associated with academic performance. Survey study, 2017 How common is migraine in women with PMS? About 1 in 7 medical students with PMS also had migraines. Most migraines occurred without visual symptoms and happened about 4 times per month. Results may not apply to all women since this studied only medical students.

Based on this one university study. Survey study, 2017 Do complementary medicine treatments work as well as medications for premenstrual syndrome? Some women using complementary medicine achieved moderate symptom relief, and many women taking medications experienced side effects. However, this study only observed what women used, not whether treatments truly worked in controlled conditions. Survey study, 2017 Is depression more common in women with severe PMS? Yes. Among women with severe PMS, 51% had depression symptoms, compared to 13.5% of women without severe PMS. Survey study, 2017 How common is premenstrual syndrome in teenage girls and what methods do they use to cope? More than half of teenage girls had at least mild PMS symptoms, and most did not use any coping strategy. The study was only one month in one school in Ethiopia, so findings may differ elsewhere. Survey study, 2017 How common is PMS in university students and is it related to depression? More than half of university students had PMS (58.1%), and there was a strong link between PMS and depression risk. Women with depression were more likely to have PMS symptoms. Survey study, 2017 Does physical activity reduce PMS symptoms? No. This study found no significant link between how much women exercise and their PMS symptoms. Survey study, 2017 Is there a link between menstrual cycle phase and fatal self-harm? Most women who died by suicide were in the premenstrual (late secretory) phase (41.7%), suggesting a possible connection. However, this is a small autopsy study from one region in India with no comparison group, so cause and effect cannot be proven. Survey study, 2017 Is premenstrual syndrome linked to anxiety, digestive problems, and food choices? Women with PMS were more likely to have anxiety and digestive problems like IBS and constipation, and to eat more meat and fast food but less carbohydrates. However, this study only shows associations, so we cannot know whether these factors cause PMS or result from it. Survey study, 2017 How many young women have premenstrual syndrome? The abstract is mostly in Polish and incomplete, so we cannot give a clear answer about prevalence from the available text. Survey study, 2016 How common are PMS and PMDD among women in Myanmar? 37.3% of the women met criteria for PMS, and 54.4% of those had PMDD. The study included only women in medicine, so these numbers may not represent all women. Study, 2016 What are the features of premenstrual syndrome and how is it treated? Premenstrual syndrome is a common disorder of young and middle-aged women with emotional and physical symptoms during the luteal phase. Calcium and evening primrose oil supplements may offer modest benefit. Survey study, 2016 Are women with PMS different in their hormones and metabolism? Yes. Women with PMS had higher prolactin and triglycerides, and lower testosterone and HDL cholesterol than women without PMS. Higher PMS scores were associated with increased metabolic syndrome risk, though we cannot tell whether these differences cause PMS or result from it. Survey study, 2016 Do women with PMDD have more difficulty regulating their emotions? Yes. Women with PMDD and PMS had significantly more difficulty with emotional regulation compared to controls, especially those with psychological symptoms. Survey study, 2016 Does eating fish help reduce PMS or PMDD symptoms in female athletes?

No clear link. This small study of 58 medical students found no significant association between PMS and insomnia, though some women with PMS did report sleep problems. Survey study, 2016 Does knowing more about menstruation help girls avoid or reduce premenstrual syndrome? Girls with less knowledge about menstruation are more likely to experience PMS symptoms. We cannot be sure whether better knowledge prevents PMS or whether girls with PMS are less likely to learn about menstruation. Survey study, 2016 How do mental health conditions change during the menstrual cycle, pregnancy, and perimenopause? Women have higher rates of depression, anxiety, and eating disorders than men. This review found that these conditions may change during the premenstrual phase and other reproductive stages, though it summarized existing research rather than testing new treatments. Survey study, 2016 Does PMS affect female medical students' learning activities? Among 125 medical students, 96.42% experienced PMS. Most students with PMS (57%) reported disrupted learning activities, but the study found no statistical link between PMS and learning performance.

Both what adolescents eat and their attitudes toward eating differ in those with PMS compared to those without. Most adolescents with PMS experienced multiple symptoms including fatigue (93.5%), irritability (91.6%), and depressive feelings (88.8%). Review, 2015 What do we currently know about premenstrual disorders like PMS and PMDD? This is a review summarising existing knowledge, not a new study: it says premenstrual disorders range from mild PMS to the more severe PMDD, the exact cause is unclear, and genetics, hormone changes, and brain chemical problems may all play a part. Survey study, 2015 Is PMDD linked to postpartum depression? Yes, strongly. Among women with postpartum depression, 34.8% had PMDD, compared to only 4.9% without postpartum depression. This suggests a hormonal connection between the two conditions. Survey study, 2015 Do emotional problems get worse before menstruation for women veterans? Yes, about 4 in 10 women veterans reported their emotional problems got worse before menstruation. Many also reported emotional changes during pregnancy, after birth, and perimenopause.

Cohort study, 2015 Is suicide more common during certain menstrual phases? No significant difference in suicide occurred during any particular menstrual phase. However, the evidence is weak because the study was small and included only women who died by suicide. Survey study, 2015 Does migraine increase during menopause, and can hormone therapy help? Women who had PMS before menopause are more likely to experience increased migraine during the menopausal transition. Continuous hormone replacement therapy, particularly using skin patches or gels, may help prevent hormone-related migraine attacks.

The study found that 55% of college girls had PMS, with 48% experiencing mild symptoms, 27% moderate, and 25% severe. Confidence is limited because this was done at one college in India. Survey study, 2015 Does sweet taste preference change with depression during the menstrual cycle? In women during their luteal phase, those with higher depression symptoms needed more sugar to taste sweetness. This connection happened only in the luteal phase, not at other times. Survey study, 2015 How common is PMS in university students and what symptoms do they experience? 85.6% of students had PMS symptoms and 36.3% had the more severe form (PMDD). The most common mood symptom was fatigue (72.6%) and the most common physical symptom was abdominal pain (62.7%). Survey study, 2014 Should PMDD be included as an official diagnosis in psychiatric manuals? The authors argue yes, because evidence confirms PMDD exists, affects a minority of women, and exists worldwide. Making it official allows affected women to receive proper recognition and treatment. Survey study, 2014 How common is PMS in adolescent girls, and does education about PMS help reduce symptoms? PMS affected 40.9% of urban girls and 51.6% of rural girls. Three months after an educational program, girls reported significant decreases in all PMS symptoms compared to before the program.

Yes, women with both conditions had more stress, more severe bowel and psychological symptoms, and longer episodes with slower recovery compared to those with IBS alone. Survey study, 2014 Is a gene called COMT a risk factor for PMS? No, not directly. A gene called COMT does not appear to be linked to PMS overall, though women with joint pain may have a connection to a specific type of this gene. Cohort study, 2014 Does exposure to PFOS or PFOA chemicals affect menstrual cycles? Higher exposure to PFOA was linked to longer menstrual cycles. However, this was a cross-sectional study that cannot prove the chemicals caused the change. Survey study, 2014 Do women's asthma symptoms get worse around their period? Up to 40 percent of asthmatic women may have worse asthma around their period. Doctors think female hormones affect the lungs, but they don't fully understand how and need more research.

A calcium cutoff of 9.40 mg/dl identified PMS with 90.9% accuracy. Survey study, 2013 What lifestyle factors are linked to PMS in college women? Family history of PMS, physical inactivity, coffee drinking, high body weight, fast food, and smoking are all linked to PMS. Together these factors explain about half of PMS cases. Survey study, 2013 How common are premenstrual disorders in adolescent girls? About 99.5% of adolescent girls reported at least one premenstrual symptom, and 59% met the criteria for PMDD. This is based on a survey in Iran. Randomised trial, 2013 What treatments work for PMS and PMDD in teenagers? At least 20% of teenagers experience moderate-to-severe premenstrual symptoms. Education, calcium, exercise, and stress reduction help mild cases, but severe PMS and PMDD usually need medication like SSRIs or hormonal contraceptives. Research on teenagers is limited. Survey study, 2013 Is PMDD linked to a higher risk of suicidal thoughts, plans, or attempts? Yes. In this large US survey, women with PMDD were more than twice as likely to report suicidal thoughts, plans, and attempts than women with no premenstrual symptoms, even after accounting for other factors.

Yes, nine months after a major earthquake, girls with PTSD showed significantly higher rates and severity of PMS and PMDD symptoms. Symptom severity increased with PTSD severity. Survey study, 2013 Does a bitter taste receptor gene affect PMS risk? This is the first study to link the TAS2R38 bitter taste gene to PMS. Women with higher sensitivity to bitter taste had more PMS symptoms, but the evidence is limited because this is a small study in one community. Survey study, 2013 Do hormonal birth control pills reduce PMS symptoms? In this study, 86% of women experienced PMS symptoms regardless of whether they used hormonal or non-hormonal birth control. Although hormonal pills should theoretically reduce PMS, this effect was not observed. The authors note results should be interpreted cautiously.

Most do. 90 percent of college students report at least one premenstrual symptom, but only a few with severe symptoms seek help. Survey study, 2013 What causes depression during pregnancy, and does PMS increase the risk? Yes. Depression during pregnancy is linked to many factors including premenstrual syndrome. Emotional support from partners and family members significantly reduces the risk. Survey study, 2013 Do women with epilepsy have more PMDD, and does the medication matter? Overall, PMDD rates are similar in women with and without epilepsy. But women with certain types of epilepsy, especially temporal lobe epilepsy, have more PMDD, and lamotrigine may reduce the risk.

Women with obesity were at higher PMS risk than those who were overweight, who were at higher risk than those with normal weight. Stress and contraceptive use also affected PMS risk. Survey study, 2012 Do women with PMDD have different ovaries or hormones than women without it? Women with PMDD had significantly fewer developing egg follicles than women without PMDD, but did not have polycystic ovaries or higher male hormones as researchers expected. Survey study, 2012 Does vitamin D affect PMS symptoms? No clear link was found between vitamin D level and PMS symptoms. However, women who ate high amounts of dairy had significantly fewer headaches and social withdrawal. Survey study, 2011 Is academic stress linked to menstrual disorders in female students? Yes. Women with academic stress have about 2 times the risk of menstrual disorders. PMS is one common disorder, affecting about one-third of those with any menstrual problem. Survey study, 2011 Does being more exposed to American culture raise the risk of PMDD in ethnic minority women? Yes, women born in the US, those who immigrated at a young age, and those who had lived longer in the US were more likely to have had PMDD, but this is based on a one-time survey so cause and effect cannot be proven. Survey study, 2011 Does experiencing discrimination increase the risk of PMDD? Yes, women who experience discrimination were significantly more likely to have PMDD. However, this study shows a link, not proof that discrimination causes PMDD. Survey study, 2011 What causes irregular periods and period pain in working women? Stress appeared to be the main factor linked to both irregular periods and period pain. However, this study only shows associations, not whether stress actually causes these problems. Survey study, 2011 Can military women successfully use birth control pills to stop their periods in field conditions? Only 21% of military women used birth control pills continuously during deployment to stop periods, mostly because taking a pill daily in harsh field conditions is difficult. Compliant users had fewer period problems than non-compliant users. Survey study, 2011 Do women with severe PMS have more personality disorders? Yes. 27% of women with severe PMS had a personality disorder compared to 0% of women without PMS. The most common was obsessive-compulsive personality disorder. Survey study, 2011 Is PTSD linked to a higher risk of PMDD? Yes. Women with trauma and PTSD were 8.14 times more likely to have PMDD than women without trauma, and women with trauma but no PTSD were 2.84 times more likely. Cohort study, 2011 How common are PMS and PMDD in teenage girls, and what causes them? PMS is very common, affecting 76% of teenage girls in this study. PMDD affected 4%. Living in a large city increased risk, but being sexually active, physically active, or differences in socioeconomic status made no difference. Survey study, 2011 Do women with PMDD experience more physical, emotional, or sexual abuse than other women? No. Women with PMDD reported similar rates of abuse as gynecological patients and healthy controls, though abuse was common in all groups. Survey study, 2011 Do asthma symptoms get worse around menstruation? In this study of Saudi women with asthma, 8.2% had asthma symptoms that got worse around menstruation. Women with more severe asthma overall were more likely to experience this pattern. Survey study, 2011 Do menstrual symptoms make IBS worse in young Taiwanese women? Yes, in this study. Digestive symptoms got worse during menstruation in young women with IBS, though this was only measured in one school in Taiwan. Survey study, 2011 How common is severe PMS or PMDD in teenage girls, and what does it look like? Almost 3 in 10 girls screened positive for severe PMS or PMDD, with irritability being the most common symptom, and the pattern looked similar to what is seen in adult women. Cohort study, 2010 How do anxiety disorders differ across different life stages? The provided summary focuses on anxiety in children and risk factors. The section about women and hormones is cut off in the provided text, so no conclusion about menstrual-related anxiety can be drawn. Survey study, 2010 Do women in different menstrual phases respond to stress differently than men? Yes. Men showed stronger hormonal stress responses than women. However, women in the luteal phase reported feeling more stressed and showed greater emotional stress hormone responses than women in the follicular phase. Case-control study, 2010 Does vitamin D intake reduce the risk of PMS? Higher vitamin D intake from food may be linked to lower PMS risk, though the evidence is weak and larger studies are needed to confirm. Survey study, 2010 How common is period pain in adolescent Asian girls and what does it affect? Three-quarters of adolescent girls in Malaysia had period pain. It affected their concentration in class for over half, limited their social activities for half, caused about one in five to miss school, and caused poor school performance in one in eight. Survey study, 2010 Is menstrual migraine genetic? About one in three to five women with migraine have migraine around their period. People with menstrual migraine may have more relatives with migraine, but we need more research to know for sure. Survey study, 2010 What causes or increases the risk of premenstrual acne? Mental stress, spicy and fried foods, stomach problems, family history, and hormone-related issues showed a clear relationship with worse premenstrual acne. Age and season did not show a clear relationship. Survey study, 2010 How many Greek nursing students have PMS or PMDD? Among 101 Greek nursing students who completed the study, 25.7% had PMS and 8.9% had PMDD. Survey study, 2010 How common is PMDD among medical students in Nigeria? 36.1% of medical students had PMDD. Menstrual pain was significantly linked to PMDD. Survey study, 2010 How common is premenstrual syndrome in female university students? PMS is very common: 85.5% of students experienced symptoms regularly. We have low confidence since this is one study from one university in Nigeria. Survey study, 2010 How common are PMS and PMDD, and who is more likely to get them? About 10.3% of women had PMS and 3.1% had PMDD. Both were strongly linked with poor physical health and psychological distress. Rates were higher in unmarried women and those aged 35-44.

Survey study, 2009 What are normal menstrual patterns in adolescent girls in Ethiopia? The median age of first period was 14.8 years, with 70% having cycles of 21-35 days. However, 75% had premenstrual symptoms and 72% had painful periods. Survey study, 2009 Do doctors diagnose and treat PMS the same way in different countries? No. Doctors in different countries use very different treatments: North America and the UK favour antidepressants called SSRIs, while France uses hormones and painkillers and Germany uses a plant extract. Few doctors diagnose PMS at all despite how common it is. Survey study, 2009 Does job stress affect periods and hormone levels in female workers? Women with higher job stress had more period problems and some hormone changes, with longer work hours linked to lower estrogen levels.

Women who experienced mood-related side effects from combination birth control pills had higher rates of mood and anxiety disorders compared to women who had no mood problems from the pills. Survey study, 2009 Does skipping breakfast affect menstrual cramps and irregular periods? Yes. Women who skipped breakfast had worse menstrual cramps, irregular periods, and poor general health compared to those who ate breakfast. This was a survey where women reported their own habits, so we can't be sure breakfast directly causes these problems. Cohort study, 2009 How common is PMDD among preschool teachers in one city? About 27.3 percent of teachers in this study had PMDD, which is higher than the 3 to 8 percent reported in general. Physical symptoms were the most bothersome.

Cohort study, 2008 How many women with asthma have symptoms that worsen around menstruation, and is it consistent across cycles? In this small study, 57% had symptoms that worsened around menstruation, but only 25% had this happen in every cycle. Birth control pills did not appear to prevent premenstrual asthma. Survey study, 2008 How common is PMDD in African women and what factors are linked to it? 6.1% of Nigerian university students had PMDD. It was strongly linked to depression (17 times more likely), anxiety, panic disorder, painful periods, and a personality trait called neuroticism. Survey study, 2008 Do prenatal vitamins with folic acid prevent depression during pregnancy?

Of those with painful periods, 31.67% frequently missed school or classes. Survey study, 2008 Do women with PMS have higher blood pressure, and could PMS predict future high blood pressure? Yes. Women with PMS have higher blood pressure in the late premenstrual phase compared to the early phase, and this may put them at risk for developing high blood pressure later. The connection may be related to stress and anxiety. Survey study, 2008 How common are menstrual problems among young women, and how much do they interfere with daily life? In this study of 112 undergraduate female medical students, 67% reported PMS and 33% reported severe period pain.

About 11.3% of menstruating women with asthma had significantly worse asthma around their period, and these women had more severe asthma overall and more emergency visits. Review, 2007 Can birth control pills be tailored to help PMS while reducing side effects? Newer low-dose pills may reduce water retention and weight gain. The right choice depends on each woman's body type and symptoms. Survey study, 2007 How common and how recognised is PMDD among young women? In this small study of Croatian students, 15 out of 87 women had PMDD, suggesting it may be more common than usually recognised, but this is from one small sample so it cannot tell us the true rate everywhere. Cohort study, 2007 Do women with depression or bipolar disorder experience premenstrual mood symptoms? 67.7% of women with major depression or bipolar disorder reported premenstrual mood symptoms, significantly more than women without mood disorders. The rates were similar between the two diagnoses. Case-control study, 2007 Does a genetic variant in the serotonin receptor gene affect PMDD risk? A genetic variant (the C version) was more common in women with PMDD. Having at least one C version was associated with increased PMDD risk, though evidence was borderline. Case-control study, 2007 Do women with severe PMS have measurable sleep problems? Women with severe PMS feel they sleep much worse before their period, but sleep measurements show similar patterns to healthy women. Some brain wave differences suggest PMS may affect sleep in subtle ways. Survey study, 2007 Do girls with asthma have less PMS? Yes, girls with asthma had significantly lower PMS rates (20%) compared to girls without asthma (46.67%). Cohort study, 2006 Do different ways of defining PMS give different prevalence rates? Yes. PMS prevalence ranged from 19% to 30% depending on the definition used. However, all definitions showed that PMS reduces quality of life and work productivity. Review, 2006 When mood changes seem tied to your cycle, is it actually PMDD? No. Many mood and anxiety symptoms tied to the menstrual cycle are not genuine PMDD. When true PMDD occurs, its impact on quality of life is similar to major depressive disorder.

Survey study, 2006 How common is PMS and what causes it? Millions of reproductive-age U.S. women experience premenstrual symptoms with varying severity. The cause appears to involve how the brain responds to normal changes in female hormones, and some people may have genetic risk. Survey study, 2006 What is premenstrual dysphoric disorder and how common is it? PMDD is now officially recognized as a distinct mood disorder linked to the menstrual cycle, affecting an important minority of women, and should be distinguished from regular PMS and depression. Review, 2006 Are sleep problems more common in women across their reproductive life? Yes. Sleep disorders are more prevalent in women than men. Sex hormones affect sleep and mood, which may explain increased risk at different life stages. Survey study, 2006 What percentage of Japanese high school girls have PMDD or PMS, and what affects it? About 8.4% have PMDD and 18.5% have PMS. Stress, poor sleep, less exercise, irregular eating, and headaches may increase risk.

Survey study, 2005 Is obesity a risk factor for PMS? Yes. Obese women had nearly 3 times the risk of PMS compared to non-obese women, though the study cannot prove obesity causes PMS. Survey study, 2005 Why do some women's asthma symptoms get worse before their period? Up to 40% of women with asthma report worse symptoms before menstruation. The exact causes aren't fully understood but may involve female sex hormones and airway inflammation. Study, 2005 What is premenstrual syndrome and PMDD and how do they affect women? PMS and PMDD are conditions related to the menstrual cycle. While some women experience mild discomfort, others experience PMDD, which significantly reduces quality of life and increases medical costs and lost work productivity. Cohort study, 2005 How common is PMS and how severe is it in young college women? More than half of college women (53%) met PMS diagnostic criteria, with 31.7% having severe symptoms. About 18% met criteria for PMDD, the most severe form. This is a high prevalence, though the study used convenience sampling in one country. Survey study, 2005 What factors are associated with having a hysterectomy in women veterans? Premenstrual syndrome was one of several factors.

Survey study, 2005 How common are PMS and PMDD in female students, and what mental health problems go with them? PMS affected 15.3% and PMDD affected 4% of female hostel students. Psychiatric illness was present in 58.62% of these women. Survey study, 2005 How does trauma history affect PMDD symptoms and pregnancy? Women with PMDD who experienced trauma show different body reactions to stress and may experience symptom changes during pregnancy. These findings come from reviewing existing published research rather than new studies. Survey study, 2004 What is PMDD? PMDD is a severe form of PMS with at least 5 of 11 symptoms, including mood changes or irritability, that happen before your period and go away when you bleed. Symptoms must last at least a year and be bad enough to disrupt daily life. Survey study, 2004 What other mental health conditions often happen alongside PMDD? PMDD commonly occurs together with mood and anxiety disorders. This review does not report specific rates of how often this happens. Survey study, 2004 Does PMS severity predict how much alcohol college women drink? PMS severity predicted weekday alcohol drinking but not weekend drinking. The link appears to exist before serious drinking problems develop. Case-control study, 2004 Is job stress linked to having premenstrual symptoms? Yes, in this large survey of military women, high job stress was the strongest factor linked to premenstrual symptoms, with almost three times the risk compared to women without symptoms, but since this is an observational survey it cannot prove that stress causes the symptoms. Survey study, 2004 Is suicide risk linked to the menstrual cycle? Women were more likely to attempt suicide during the follicular phase (early cycle). The reason is unclear, though low estrogen and progesterone in this phase may play a role, but hormones alone do not explain it. Cohort study, 2003 Do women with PMDD who experienced abuse respond differently to stress? Women with PMDD who had experienced sexual or physical abuse showed different stress hormone patterns when stressed, with lower resting stress hormones but stronger adrenaline responses, different from non-PMDD women with abuse histories. Survey study, 2003 Do women with PMDD act more aggressively before their period? Yes, clearly. Women with PMDD used more aggressive tactics during the premenstrual phase and had higher rates of verbal and physical aggression overall compared to women without PMDD. Survey study, 2003 Do women who experienced recent abuse have more health problems than other women? Yes. Four percent of women at gynecology clinics reported recent abuse. Women who reported abuse had more mental health diagnoses, more physical symptoms, more stress, and worse overall health compared to women without abuse. Survey study, 2003 Do work conditions make premenstrual and menstrual symptoms worse? Yes. Physical work demands and job stress were the biggest work-related factors that made symptoms worse. Chronic illness and alcohol use also made symptoms worse. Survey study, 2003 How common is PMS and does it affect academic performance in university students in Ethiopia? 27% of students met diagnostic criteria for PMS or PMDD. About 14% frequently missed classes and 15% missed exams or got lower grades due to PMS symptoms. These academic impacts were significantly associated with symptom severity. Survey study, 2003 How common is PMS and what factors are associated with it in college-aged women in Saudi Arabia? 96.6% experienced at least one premenstrual symptom and 37.5% had high severity. Risk factors included maternal history of PMS, perceived mental stress, physical inactivity, and consuming sweet foods and coffee, though these explained only 14% of symptom variation. Case-control study, 2003 Does PMS affect balance and body awareness during the menstrual cycle? Yes. Women with PMS had significantly worse balance and less ability to feel their knee joints moving compared to women without PMS. Review, 2002 Are women more likely to get depression, especially due to hormonal changes? Yes. Women have 1.7 to 2.7 times higher risk of depression in their lifetime compared to men, and hormonal changes around puberty, periods, and menopause increase that risk. Survey study, 2002 Do birth control pills affect mood? Birth control pills help most women's mood by reducing mood swings and sadness during menstruation. However, some women experience worse mood while taking them, especially those with a history of depression or pregnancy mood problems. Case-control study, 2002 Do difficult childhood experiences with parents cause PMDD? No. Women with PMDD reported no worse childhood parenting experiences than women without PMDD, suggesting PMDD comes from biology rather than childhood experiences. Randomised trial, 2001 Why does asthma get worse before a period and how is it treated? Up to 40% of women with asthma experience flare-ups before their period, likely due to female hormones and changes in airway reactivity. Most respond to regular asthma treatment, though some may benefit from hormonal birth control. Cohort study, 2001 Does having PMDD increase the risk of developing major depressive disorder? In this small pilot study, 7 of 8 women with PMDD developed major depressive disorder within two years. However, this needs confirmation in much larger studies. Survey study, 2001 How common is premenstrual dysphoric disorder and how is it related to other psychiatric conditions? About 75-85% of women report some premenstrual symptoms, but only 10-15% seek care and 2-5% experience serious disruption to work or social life. PMS may worsen other psychiatric conditions. Study, 2001 Does estrogen or progesterone affect magnesium levels in brain blood vessels? Yes. High levels of estrogen and progesterone both decrease magnesium in brain blood vessel cells. Low progesterone increases magnesium. This may explain why migraines happen more often before the period. Survey study, 2001 Do women's beliefs about PMS change how they remember their symptoms? Women report more premenstrual symptoms when remembering them than when tracking them day by day. Women who believe PMS is very common are especially likely to exaggerate their remembered symptoms. Cohort study, 2000 How common is PMDD among women in India? In this study, 6.4% of women met the criteria for PMDD, which is similar to rates found in other countries. Survey study, 2000 Does premenstrual worsening of panic disorder increase suicide risk in women? Yes. Women with panic disorder who experienced premenstrual worsening had higher suicide risk scores and were more likely to be considered suicidal than women whose panic did not worsen premenstrually. This was independent of depression. Randomised trial, 2000 How common is sexual abuse history in women seeking treatment for severe PMS? Very common. Of 42 interviewed women, 95% reported at least one sexual abuse event, and 81% reported completed penetration against their will. Most also had undiagnosed post-traumatic stress disorder. Survey study, 2000 Are women with PMDD more likely to have had mental health problems? This review questions the common belief that women with PMDD have higher rates of past psychiatric disorders. It suggests this assumption may be premature, but does not provide new research to confirm either way. Survey study, 2000 How do female hormones affect migraines and headaches? Estrogen withdrawal appears to trigger menstrually-related migraines rather than sustained high or low hormone levels. Migraines are much more common in adult women than in men. Cohort study, 1999 Do women with PMS have a higher risk of depression later in life? In a 5 to 12 year follow-up study, women with PMS had a nonsignificantly higher rate of new depression, but this difference disappeared when comparing only women who had no prior depression history, suggesting prior depression rather than PMS drives the risk. Study, 1999 Why is depression more common in women than men? Women are twice more likely than men to suffer from depression. This is related to biological, psychological, and social factors, especially during reproductive years when hormone changes occur. Survey study, 1999 Do nursing interventions help relieve PMS symptoms? Yes. Educational nursing interventions proved effective in relieving PMS and improving students' practices during the premenstrual period. Survey study, 1999 What are the main symptom clusters in PMS and how do they vary during the menstrual cycle? Four main clusters were identified: turmoil, fluid retention, somatic symptoms, and arousal symptoms. Some clusters remain consistent across the cycle, while others change more. Non-randomised trial, 1999 Do women seeking PMS treatment actually have underlying mood or anxiety disorders? About 39% of women seeking PMS treatment meet criteria for mood or anxiety disorders. Mood disorders were about twice as common as anxiety disorders. Survey study, 1999 Do bowel symptoms vary with the menstrual cycle in women with IBS and inflammatory bowel disease? Yes. About two-thirds of women with Crohn's disease and ulcerative colitis reported that their symptoms got worse with their cycle. Women with IBS and inflammatory bowel disease reported more cyclical changes in bowel habits than women with normal bowel function. Study, 1998 Do women attempt suicide more often at certain times in their menstrual cycle? Yes. Suicide attempts were most common in the first week of the menstrual cycle (when the period starts), with 36% of attempts happening then. The fourth week (premenstrual) had 29%. Other weeks had lower rates (19% in week 2, 16% in week 3). Survey study, 1998 How common and severe are premenstrual symptoms in teenage girls? Premenstrual symptoms are nearly universal. 88% reported moderate or worse symptoms and 56% reported extreme severity. Older teenage girls had significantly more intense symptoms than younger ones. Survey study, 1998 How common is PMS in women of reproductive age and what factors increase the risk? 30.4% had PMS, with most having mild to moderate symptoms. Women with higher stress, depression symptoms, painful periods, and higher education level had higher rates. Case-control study, 1998 Does the menstrual cycle affect bowel disease symptoms? Yes, significantly. Women with bowel disease reported much more cyclical bowel symptoms than healthy women, with Crohn's disease patients particularly affected. Survey study, 1997 How is premenstrual dysphoric disorder treated? Multiple treatments help PMDD, including antidepressants (particularly SSRIs), psychotherapy, sleep deprivation, and light therapy. SSRIs showed the best results among medications. Survey study, 1997 How common are premenstrual symptoms, what treatments do women use, and do they work? Between 11-32% reported severe or extreme symptoms, and 85% had tried treatments. Women reported that dietary changes, evening primrose oil, vitamins, and exercise worked best. Non-randomised trial, 1997 Does the flavonoid supplement Daflon 500 mg reduce PMS symptoms? Yes, though results need confirmation. PMS disappeared completely in 37.4 percent. Duration dropped 2.6 days. Bloating decreased 60 percent. But there was no control group, so certainty is limited. Survey study, 1997 Do marked mood changes happen mainly before menstruation? Marked mood changes happen just as often after menstruation as before, so cycle phase is not a good predictor of mood. Social relationships predict mood changes much better than cycle timing does. Survey study, 1996 Is there a link between the menstrual cycle and suicide attempts? The study found a possible difference in suicide attempts during pre-ovulation, but this finding was unreliable. Both groups visited hospitals more during pre-ovulation, suggesting the pattern may reflect hospital visiting patterns rather than a real link to suicide attempts. Non-randomised trial, 1996 Do women with PMDD have different brain wave patterns linked to alcoholism risk? Yes. Women with PMDD showed different patterns in brain waves and electrical responses compared to healthy women. Those with a family history of alcoholism showed even more pronounced differences, suggesting PMDD and alcoholism risk may share biological mechanisms. Survey study, 1996 How common is premenstrual dysphoric disorder in the general population? About 3-10% of women have premenstrual dysphoric disorder severe enough to disrupt work or social life. About 30.5% have enough symptoms to meet diagnostic criteria. Survey study, 1996 Are women happy taking the birth control pill and what side effects do they experience? Most women are happy with the pill. Periods become shorter and lighter, though some experience weight gain and breast tenderness. Survey study, 1995 How common are PMS and premenstrual symptoms? About 7.7% of women met the strict diagnosis for PMS, but 42.4% had some premenstrual symptoms. Age, oral contraceptive use, and life circumstances affected whether women had symptoms. Survey study, 1995 What's different about women who seek treatment for premenstrual mood changes? Women seeking treatment reported significantly more depression, anxiety, and unwanted negative thoughts than those not seeking treatment. Both groups had similar physical symptoms. The commonly used 30% improvement rule did not distinguish the two groups well. Survey study, 1995 Is premenstrual syndrome related to depression? The evidence suggests yes. Women with PMS are more likely to have had depression, and antidepressants help both conditions. Survey study, 1995 Are certain personality traits linked to PMS? Women with PMS have higher scores on harm avoidance and novelty seeking compared to the general population. These traits are modestly linked to specific symptom patterns. Survey study, 1995 Do premenstrual symptoms differ between rural and urban Mexican women? Physical symptoms were similar. Urban women reported more severe psychological and behavioral symptoms than rural women. Survey study, 1995 Does the uterus cause premenstrual symptoms? Women who had their uterus removed showed large improvements in premenstrual symptoms. This suggests the uterus may play a role, though the study cannot prove this. Survey study, 1995 Is depression being missed in women's health care? Depression is twice as common in women as in men and occurs in as many as 21% of women over their lifetime. Doctors often miss it because depression hides behind complaints about other gynecologic problems. Cohort study, 1994 How common is premenstrual syndrome in teenage girls? PMS affects about 1 in 7 teenage girls (14%). Girls with PMS reported more anxiety, trouble concentrating, and poor health, though childhood factors did not predict who would develop it. Case-control study, 1993 Are hormone levels different in women with PMS? Possibly. Women with PMS had lower ACTH levels during the luteal phase, and different subgroups showed different hormone patterns, suggesting multiple biological subtypes. Survey study, 1993 How common is premenstrual tension among nurses in Kenya? Very common. 95.5 percent of 400 nurses studied reported premenstrual tension, with breast tenderness and bloating being the most frequent symptoms. Case-control study, 1992 Is premenstrual tension a risk factor for ovarian cancer? This study found that premenstrual tension is not a risk factor for ovarian cancer, though older age at menopause and hot flashes were associated with increased risk. Non-randomised trial, 1992 Does a new birth control pill with norgestimate control the menstrual cycle well? Yes. Most women had normal bleeding patterns with minimal clinically insignificant changes in flow, cramps, and premenstrual tension. The large sample makes this strong, but no control group limits what we can conclude about the pill itself. Survey study, 1992 How common are different types of premenstrual symptoms? Premenstrual symptoms were very common, ranging from 36% for breast pain to 66% for stomach and back cramps. Multiple factors including education, when periods started, menstrual irregularity, and pregnancy history were linked to having symptoms. Survey study, 1992 How should doctors diagnose premenstrual syndrome? PMS diagnosis should include mood symptoms like irritability, anxiety, depression, or fatigue, along with a physical symptom like bloating or breast tenderness. Doctors need to ask women about symptoms every day for a full cycle, not rely on blood tests or personality assessments. Survey study, 1991 Are sugary foods and drinks linked to premenstrual syndrome? Among women with severe PMS, eating chocolate was linked to PMS while other junk foods were not. Drinking alcohol, fruit juice, and caffeine-free soda were all linked to PMS in these women, with associations holding even when caffeine intake was controlled for. Survey study, 1991 How common are menstrual symptoms in working women? The most common symptoms were weight gain and swelling (over 60% of women), followed by anxiety, tension, irritability, fatigue, cramps, breast pain, mood swings, and food cravings. Symptoms were more common in younger women. Survey study, 1991 What percentage of Pakistani women have PMS? 33% of the 1600 women in Karachi had PMS. It was more common in women with lower socioeconomic status. Survey study, 1991 What mental health and social problems do women with PMS have? Most women seeking PMS treatment (67 percent) had a psychiatric disorder, with depression and anxiety being most common. Sexual dysfunction and social problems were also frequent. Survey study, 1990 Do bowel symptoms get worse during menstruation? Yes. 34% of women without IBS reported gas, diarrhea, or constipation during menstruation, and women with IBS were significantly more likely to experience these symptoms during their period. Survey study, 1990 How common is tuberculosis of the uterine lining in infertile women in Nigeria? Very rare. The study found 10 cases in 4700 samples, giving a prevalence of 0.2%. Cohort study, 1990 Do women with PMS release hormones differently than women without symptoms? Women with PMS show significantly higher frequency of LH hormone pulses (the hormone that triggers ovulation) compared to women without symptoms, though the pulses are smaller. This suggests a possible brain hormone system dysfunction in PMS. Cohort study, 1990 Can premenstrual depression predict whether a woman will develop major depression later? Yes, women whose premenstrual depression scores are higher have a greater risk of developing major depression in the future, and this predictive value holds even after accounting for family history and past depression. Survey study, 1990 Do women with PMDD have a history of depression or other mental health problems? Yes. 78% of women with PMDD had a lifetime history of other mental disorders, most commonly depression. 29% of those who had given birth reported postpartum depression. Survey study, 1990 What makes some women with PMS see a doctor while others don't? No. Women who see a doctor for PMS don't have worse symptoms than those who don't, but they do have higher levels of psychological problems. Survey study, 1989 Are premenstrual symptoms as common as period pain in teenage girls? Premenstrual symptoms are very common in teenage girls (86%), as common as period pain (91%). Most girls don't know what causes these symptoms or how to treat them. Cohort study, 1989 What psychological factors are connected to confirmed premenstrual dysphoria? Women who tracked their mood every day and reported PMS symptoms had significantly higher anxiety, depression, and negative self-talk than others. But women who only remembered having PMS after the fact did NOT differ from controls, showing memory is unreliable. Survey study, 1989 How does sample selection affect reported prevalence of premenstrual disorder? Different subtypes of premenstrual disorder exist, but how common each type is depends heavily on whether women were seeking help for premenstrual problems or recruited from the general population. Study, 1989 Are there differences in how the brain processes language during different parts of the menstrual cycle? In women who experience worse mood before their period, the brain processes language differently and they perceive fewer positive words in the premenstrual phase compared to the follicular phase. Survey study, 1989 Are women with premenstrual symptoms more likely to have mental health problems? Yes, clearly. About 85% of women experienced moderate to severe symptoms before their period, and women with these symptoms scored significantly higher on mental health screening than those without. Survey study, 1988 How common are premenstrual symptoms and do they interfere with daily life? Premenstrual symptoms are very common (87% lifetime prevalence), but most are mild to moderate. Only 3.2% report severe symptoms, and few women report that symptoms interfere significantly with work. Survey study, 1988 How common is severe PMS and does it affect work attendance and healthcare visits? Severe premenstrual symptoms were common, occurring in 44% of women with strong symptoms and 18% with acute symptoms. Women with severe symptoms were more likely to miss work and visit doctors for menstrual problems. Cohort study, 1988 What makes a woman more likely to have PMS that's confirmed by daily tracking rather than just by memory? Working outside the home was linked to a higher chance of having confirmed PMS, and being older was linked to a lower chance; but strictly defined PMS, confirmed by daily mood tracking, turned out to be uncommon even among women who thought they had it. Survey study, 1987 How common are premenstrual symptoms in the community? Very common, ranging from 39 percent for breast swelling to 81 percent for weight gain. Socioeconomic status, race, and breast disease history were linked to more symptoms. Survey study, 1987 When in the menstrual cycle do symptoms reach their peak? Symptoms peak during menstruation, not before it. Only 13 percent of women showed a pattern of symptoms worsening before menstruation. Survey study, 1987 How common are premenstrual symptoms in women in Wellington? Most women reported at least one premenstrual symptom, and about half said these symptoms affected their daily life. Survey study, 1986 Do women with severe PMS have more psychiatric illness? Yes. Women with moderate to severe perimenstrual symptoms had significantly higher lifetime rates of depression and drug abuse than women with mild or no symptoms. Survey study, 1986 Is premenstrual syndrome more common in women with low sexual desire? Yes. Significantly more women with low sexual desire had severe premenstrual syndrome than women without sexual dysfunction. These women also had higher rates of depression. Cohort study, 1986 How common are symptoms linked to the menstrual cycle? At least 40% of women experience some symptoms tied to their menstrual cycle. Only 2% to 10% report severe symptoms. When women remember their symptoms later, they may report more variation than they reported as it was happening. Cohort study, 1986 Can we tell women with PMS apart from women with mood disorders based on symptoms? Not easily. Reported PMS symptoms alone cannot reliably identify women with diagnosed PMS. Women with mood disorders reported fewer PMS-like changes than expected from previous research. Survey study, 1986 How common are hostile feelings and social problems before periods? These symptoms vary greatly by group studied: from 15% to 83% for hostile feelings, and from 14% to 92% for social functioning problems. Survey study, 1986 Do Black women and White women experience PMS differently? No clear difference. Black women and White women reported similar rates and severity of premenstrual symptoms, except Black women reported more food cravings. The difference in who seeks treatment is likely due to social and cultural factors, not differences in symptoms. Survey study, 1986 Is severe premenstrual syndrome similar to depression? Women with severe PMS report more depressive-like symptoms than those with mild PMS. The study suggests these may reflect underlying depression, but as a survey without medical testing, we cannot be sure. Survey study, 1985 Do the same premenstrual symptoms happen every month in the same woman? No. Most symptoms vary from month to month. Only 3 menstrual symptoms (backache, headache, cramps) and 5 premenstrual symptoms (backache, cold sweats, fatigue, depression, tension) showed consistent reporting across two months. Survey study, 1982 What percentage of women have premenstrual tension symptoms? Half the women in the study had at least one type of premenstrual tension symptom. Anxiety and mood changes, and swelling and bloating, were the most common types. Survey study, 1975 Are psychological factors linked to menstrual symptoms? Psychological factors were linked to some menstrual symptoms like pain and mood changes, but not to others like water retention. The sample was small and the study is from 1975. Survey study, 1972 How does the menstrual cycle affect mood and sexual arousal? The menstrual cycle affects mood in women. The strongest effects occur before the period, when some women become depressed or irritable. Physical symptoms also accompany these mood changes. Review, 1971 Could hormone-driven changes in brain chemicals explain premenstrual mood swings? This 1971 review suggests that shifting levels of ovarian hormones (estrogen, progesterone, aldosterone) during the cycle may affect mood by altering brain chemicals called monoamines, but this is a theory built from combining older human and animal studies, not a new trial in women with PMS. Survey study, 1970 How common is PMS in medical students? All of the medical students surveyed had at least some PMS symptoms, even if mild. Irritability and compulsivity were the most common symptoms. Earlier years of study had slightly worse symptoms than later years. Survey study, 1964 How common are mood and physical changes around menstruation? Very common. One in nine women reported severe pain, irritability or headache, and one in four had moderate to severe premenstrual tension. Psychological symptoms were linked to personality traits related to anxiety. Show more studies Ask AI about this page Copy prompt ChatGPT ↗ Claude ↗ Perplexity ↗ Google AI Mode ↗ Grok ↗
