In a recent cross-sectional study, irregular or long menstrual cycles were associated with increased NAFLD incidence and prevalence risk in young, premenopausal women. Of 72,092 women, 36,378 (27.7%) had menstrual cycles of 26-30 days and were identified as the index group. The prevalence of NAFLD in this group was 5.8%. For those with a menstrual cycle of 31-39 days, the prevalence rate climbed to 7.2%. For those with a menstrual cycle of at least 40 days or too irregular to estimate, the prevalence was 9.7%. The prevalence was 7.1% for those with a menstrual cycle less than 21 days.

Although the mechanism is unclear, estrogen exposure appears to be the factor connecting NAFLD and longer, more irregular periods. The researchers concluded that women with irregular or long menstrual cycles may benefit from advice concerning lifestyle modification and risk reduction for NAFLD and related cardiometabolic diseases.
