To  characterize depression symptoms over time and  test the hypothesis that adverse metabolic parameters would associate with risk of enduring depression risk in women with polycystic ovary syndrome (PCOS).
Prospective cohort study.
One hundred sixty-three women with PCOS.
The Beck Depression Inventory Fast Screen (BDI-FS) was self-administered at baseline and follow-up to identify depression risk, using a cutoff score >4.
Main Outcome Measure(s)
Median baseline age was 29.0 years, and median follow-up interval was 5.5 years. Fifty-nine of 163 women had positive depression screens at baseline (36%); 52 women (32%) screened positive at follow-up. Median change in BDI-II score was 0 (interquartile range, –2, 1) over the study period. Of the 59 women at risk for depression at baseline, 22 screened negative at follow-up (37%), while 37 women remained at risk (63%). Considering these 59 women with positive depression screens at baseline, higher body mass index (BMI) was associated with increased odds of enduring depression risk at follow-up (adjusted odds ratio = 1.09; 95% confidence interval, 1.00, 1.18), in a multivariate logistic regression model. Compared with women with normal body weight at baseline, obese women (BMI >30 kg/m2) had five-fold increased odds of enduring depression risk at follow-up (adjusted odds ratio = 5.07; 95% confidence interval, 1.07, 24.0).
The prevalence of depression was relatively stable over time in a cohort of women with PCOS. Elevated BMI is a hallmark of enduring depression risk. These results may assist providers in developing targeted intervention strategies to reduce the prevalence of long-term depressive symptoms in women with PCOS.
