SARS-CoV-2 infection and subsequent changes in the menstrual cycle among participants in the Arizona CoVHORT study





Objective


The menstrual cycle involves complex interactions between various tissues, hormones, and organ systems. As such, the menstrual cycle is sensitive to endogenous and exogenous factors, including infection and changes in lifestyle. Over a year into the global COVID-19 pandemic caused by SARS-CoV-2, there is increasing interest in understanding the post-acute sequalae of SARS-CoV-2 (PASC) following infection. Emerging evidence suggests that SARS-CoV-2 infection, COVID-19 vaccination, and/or psychological stress related to the COVID-19 pandemic may influence the menstrual cycle. , However, there is a paucity of scientific research on these topics. Therefore, our objective was to describe SARS-CoV-2 infection and the menstrual cycle changes because of it.


Study Design


In May 2020, the Arizona CoVHORT study began recruiting individuals for a prospective, population-based cohort, with the purpose of identifying the long-term consequences of COVID-19. The design of CoVHORT study has been previously published. Briefly, SARS-CoV-2-positive cases were recruited through case investigations as part of an academic-health department partnership with several health departments and testing centers across Arizona. We restricted our analysis to SARS-CoV-2-positive participants who were 18 to 45 years old, identified as women or nonbinary, and were not currently or recently pregnant as of January 2020. The participants reporting laboratory-confirmed or suspected SARS-CoV-2 infection were administered “symptom surveys” focused on COVID-19 symptomology at approximately 6-week intervals. All the study procedures were approved by The University of Arizona Institutional Review Board (approval number 2003521636A002).


At baseline, the participants reported their demographics, stress, and the self-reported severity of COVID-19 illness (score range 0–10). The participants were also asked if they had noticed menstrual cycle changes as an ongoing symptom or a new one related to their COVID-19 illness. If endorsed, they were asked “What changes to your menstrual cycle have you noticed?” We compared demographics, comorbidities, self-rated COVID-19 severity, self-reported stress measured by the Perceived Stress Scale-10, and COVID-19 symptomology among the participants who reported a change in their menstrual cycle and those who did not. The comparisons were made using t -tests, chi-squared tests, and Poisson regression where appropriate.


Results


Among the SARS-CoV-2 positive participants (n=127), 16% reported changes in their menstrual cycle ( Table ). The median number of days between a positive SARS-CoV-2 test and the last reported menstrual cycle changes was 57.5 (range, 28–222). Compared with the SARS-CoV-2-positive participants who did not report changes, those who did report changes to their menstrual cycle were more likely to report a greater number of COVID-19 symptoms (8.6 vs 6.1; P =.01) and to identify as Hispanic (50% vs 25%; P =.03). The SARS-CoV-2-positive participants who reported changes to their menstrual cycle were more likely to be overweight or obese (60% vs 44.9%; P =.2) and to report higher self-rated illness severity scores (5.3 vs 4.4; P =.14) than those who did not report changes. However, these comparisons did not reach the threshold of statistical significance. When comparing the most common COVID-19 symptoms, the individuals who reported changes to their menstrual cycle were more likely to report fatigue ( P <.01), headache ( P =.002), body aches and pains ( P =.002), and shortness of breath ( P =.002) as COVID-19 symptoms compared with the participants who did not report changes to their menstrual cycle. Among the participants who reported changes to their menstrual cycle, the most commonly reported changes were irregular menstruation (60.0%), an increase in premenstrual syndrome symptoms (45.0%), and infrequent menstruation (35.0%).
