Survey study, 2024 # Did having COVID-19 cause lasting menstrual problems? No clear difference was found in menstrual cycle patterns or PMS symptoms between vaccinated women who had COVID-19 and those who had not had it. Moderate study design 220 Brazilian women aged 18-25 years, all of whom had received at least one COVID-19 vaccine. ## What they did Asked 220 Brazilian women aged 18-25 (all vaccinated against COVID-19) about their menstrual cycles and filled in surveys about menstrual problems and stress. The researchers compared women who had previously had COVID-19 with those who had not. ## What they found Menstrual cycle patterns were similar in both groups. PMS symptom scores were similar in both groups. Stress related to COVID was similar in both groups. No clear differences were found in any of these measures. ## What it means for you Having had COVID-19 did not appear to cause lasting menstrual problems in young vaccinated women at the time of this study. Reports of menstrual changes were more common earlier in the pandemic, likely due to stress. The main limit is that all women were vaccinated, so results may not apply to unvaccinated women. 220 Women studied 18-25 Age range (years) All vaccinated COVID-19 vaccination status ## About the study Original title Comparison of menstrual cycle irregularities among young women based on coronavirus disease 2019 infection status: a cross-sectional study Authors Doğan E, Uncu B, Duman R Journal Revista da Associacao Medica Brasileira (1992) Year 2024 Study design Survey study Participants 220 What was tested None.

The Severe Acute Respiratory Syndrome Coronavirus 2 virus has significant effects on women's health due to gender-related physiological differences. The aim of this study was to compare the menstrual cycle status of young women according to their status of having had coronavirus disease 2019. Methods: This descriptive cross-sectional study was conducted with 220 young women aged between 18 and 25 years who received at least one dose of coronavirus disease 2019 vaccine. The study data were collected as a survey on the online platform. Results: The descriptive characteristics of young women who had had and had not had coronavirus disease 2019 were distributed homogeneously between the groups (p>0.05). Furthermore, there was no statistical difference in terms of menstrual cycle patterns (p>0.05). The mean scores from the Premenstrual Syndrome Scale and its subscales and the mean scores from the COVID Stress Scale and its subscales were similar in both groups, and no statistically significant difference was identified (p>0.05). Conclusion: Although menstrual cycle irregularities due to coronavirus disease 2019 have been reported, these effects are usually observed during the pandemic. A decrease in stress and anxiety with the end of the pandemic may explain the return of the menstrual cycle to normal.
