Lifestyle, Anxiety,Depression, and Clinical Profile in Women With Polycystic Ovary Syndrome: Initial Results From the Brazilian PCOS Study

Brazil is a large country with rich cultural and ethnic diversity among its different regions. In this ongoing nationwide collaborative study, we are evaluating modifiable lifestyle factors, metabolic and reproductive abnormalities and prevalence of anxiety/depression in a less-well represented population of women with PCOS from Brazil. The design of the Brazilian PCOS study has been published previously(1). Briefly, the study is being conducted in the outpatient clinics of university hospitals within the public health care network (Unified Health System - SUS) across the country. The sample includes women with PCOS diagnosed according to Rotterdam criteria and a control group of healthy women matched by age and geographic region. Collected data are being incorporated into a unified cloud database. Two hundred five participants have been enrolled thus far (17% of an expected sample size of 1,200 women). Age, years of formal education and socioeconomic class were similar among PCOS phenotypes and the control group. The prevalence of PCOS phenotypes in this sample was 64.7% for phenotypes A + B, 25% for phenotype C, and 10.3% for phenotype D. Phenotypes A + B and D had higher prevalence of obesity (BMI>30) (p=0.001) and metabolic syndrome as compared to the other groups (32.4% in A + B and 50% in D vs. 16% in C and 5.9% in controls; p=0.002). Total testosterone levels, determined by mass spectrometry were higher in PCOS A+B than in the other phenotypes, even after adjustment for BMI (p<0.001). Sedentariness (<150 min/week of physical activity) was present in more than 60% of participants in all PCOS phenotypes and in controls, with no difference between the groups. More than 70% of participants in all PCOS phenotypes had a fruit and vegetable intake below 5 portions/day. Anxiety/depression (SRQ-20) was frequent in phenotypes A + B (41.6%) and D (56.3%) vs. phenotype C (23.1%) and controls (28.6%) (p=0.062). These initial results suggest that PCOS participants, besides often presenting metabolic abnormalities have an unhealthy lifestyle and high prevalence of psychological distress. Analysis of the full study sample will be useful to guide specific public strategies for primary and secondary prevention of psychological, metabolic and reproductive comorbidities in the PCOS population of Brazil. 1Spritzer PM, et al.
