Abstract
Introduction: Available evidence suggests that there might be an association between the stressors experienced during the COVID-19 syndemic and changes in menstrual patterns. The aim of this study was to assess self-reported menstrual alterations during the COVID-19 syndemic among women and people who menstruate aged 18-55 in Spain. Materials and Methods: A cross-sectional online survey-based study was conducted (March-July 2021). Descriptive statistics were calculated and multivariate logistic regression models were constructed. This study was conducted as part of the "Equity and Menstrual Health in Spain" research project. Results: Among participants (N=17,455), 39.4% reported menstrual alterations since the start of the syndemic. Participants self-reporting long COVID-19 presented higher odds of menstrual alterations (aOR: 1.34, 95% CI, 1.15-1.57). In participants with no history of COVID-19, the risk for self-reported menstrual alterations was significantly higher based on employment situation, among participants experiencing financial issues (eg, financial issues always/many times <12 months: aOR: 1.68, 95% CI, 1.48-1.90), poorer self-perceived health (eg, poor: aOR: 2.00, 95% CI, 1.31-3.07), and those diagnosed with polycystic ovary syndrome (aOR: 1.13, 95% CI, 1.02-1.26). Among participants with a self-reported COVID-19 diagnosis, factors that significantly increased the odds for menstrual alterations were experiencing financial strains (eg, financial issues always/many times <12 months: aOR: 1.53, 95% CI, 1.09-2.14), poorer self-perceived health (eg, poor: aOR: 3.09, 95% CI, 1.01-9.52). Overall, factors that decreased the odds of reporting menstrual alterations included age >25, being a carer, not having a gynecological condition and using hormonal contraception. Discussion and conclusions: Findings suggest an impact of the COVID-19 syndemic on menstrual patterns. Social inequities in reporting menstrual alterations were identified. While the risk of reporting menstrual alterations was higher among participants with long COVID-19, evidence is not conclusive. Further research on menstrual health in the context of COVID-19 is needed, also to inform policy and practice.
