Case-control study, 2004 # Do menstrual characteristics and pregnancy history predict depression risk? Yes, earlier age at first period, heavier periods, and irregular periods in early menstruation predicted higher depression risk. Women with multiple miscarriages or abortions had 2-3 times higher depression risk. Moderate study design 4161 premenopausal women aged 36-45 years; 332 with major depression and 644 with no depression history ## What they did Population-based case-control study of 4161 premenopausal women aged 36-45. Researchers identified 332 women who met criteria for major depression and 644 without depression history. Detailed interviews covered menstrual cycle characteristics from first period through study enrollment and pregnancy history. ## What they found Depression risk increased significantly with earlier age at first period (P<0.001). Higher depression risk was associated with heavier menstrual flow and cycle irregularity during the first 5 years of menstruation. Women with multiple abortions were 2-3 times more likely to develop depression (95% CI 1.6-4.1). More months of breastfeeding was associated with decreased depression risk, especially postpartum depression (P=0.012). ## What it means for you Menstrual and pregnancy history may help doctors identify women at risk for depression. However, the study relied on women's memory of past events, which can be inaccurate. These associations should be confirmed in prospective studies before relying on them clinically. 4161 total number of women 2-3 times higher depression risk with multiple abortions P < 0.001 earlier menarche increases depression risk ## About the study Original title Early life menstrual characteristics and pregnancy experiences among women with and without major depression: the Harvard study of moods and cycles Authors Harlow BL, Cohen LS, Otto MW et al.
