Body mass index, menstruation, acne, and hirsutism of polycystic ovary syndrome in women: A cross-sectional study.

We examined to compare menstruation and body mass index (BMI) in women with and without polycystic ovary syndrome (PCOS) and to explore the effects of BMI on menstruation, facial acne, and hirsutism in women with PCOS of child-bearing age. Data from the Korea Nurses' Health Study were analyzed. The effect of BMI on irregularity of menstruation, acne, and hirsutism in the PCOS group was analyzed by logistic regression. The prevalence of PCOS was 7.1% among 11,866 participants. We found that BMI affects menstrual irregularity, facial acne, and hirsutism in PCOS women. Healthcare providers should consider weight control to improve irregularity of menstruation and hirsutism in PCOS women.
