Abstract

Objectives To evaluate in a sample of Chilean adult women, the association between adiposity markers with pattern and length of the menstrual cycle, assessing the influence of metabolic markers and hormones in this relationship. Study design We conducted a cross-sectional study involving 401 premenopausal women belonging to the DERCAM study (Determinants of Breast Cancer Risk) from Santiago, Chile. The menstrual cycle pattern was defined as regular or irregular, while menstrual cycle length was categorized as short (≤25 d), normal (26-31d), and long (≥32d). Adiposity markers included body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and body fat percentage (BFP). Insulin, sex-hormone-binding globulin (SHBG), estrone (E1), estradiol (E2), androstenedione (A2), follicle-stimulating hormone (FSH) and progesterone were measured in the follicular phase of the menstrual cycle. Results There was no association between adiposity markers and cycle patterns. However, after all, metabolic and hormonal adjustments, women in the third tertile of BFP (RRR = 2.63; 95% CI: 1.21.5.69) were more likely to have longer menstrual cycles. Conclusion Women with high BFP presented a higher risk of having irregular menstrual cycles, which was an indicator of reproductive disorders; this relationship could be partially mediated by hormonal markers, especially SHBG, E1, and insulin levels.
