SUN-013 Cardiometabolic Profile of Brazilian Women with Polycystic Ovary Syndrome (PCOS): A Systematic Review and Meta-Analysis

Introduction. PCOS is a frequent endocrine disease and its clinical expression may be influenced by ethnicity and sociocultural backgrounds. Despite its high prevalence, few studies are available regarding clinical characteristics of Brazilian women with PCOS. The aim of this study was to summarize the available evidence regarding metabolic risks in PCOS population in Brazil trough a systematic review and meta-analysis. Materials and Methods. We systematically searched EMBASE, MEDLINE, Cochrane Central Register of Controlled Trials for studies published until July 31, 2019. Results. Eleven cross-sectional and case-control studies were selected for the present meta-analysis, including 898 women diagnosed with PCOS and 2176 controls. All used the Rotterdam criteria for the diagnosis of PCOS. Compared to controls, BMI was higher in PCOS [standardized mean difference (SMD) 0.67 (95% CI 0.29, 1.05) I²=91%], as well as waist circumference [SMD 0.88 (0.40, 1.37) I²=93%]. Systolic and diastolic blood pressure were higher in PCOS, SMD 0.66 (0.30, 1.01) I²=83%, SMD 0.55 (0.24, 0.87) I²=81%, respectively. Glucose and HOMA-IR were higher in PCOS, SMD 0.22 (0.02, 0.41) I²= 57%, SMD 0.78 (0.52, 1.04) I² =26% respectively. Regarding lipid profile, PCOS had higher values for triglyceride [SMD= 0.39 (0.14, 0.64, I² =63%)], total cholesterol [SMD 0.36 (0.15, 0.57, I²=57%)] and LDL [SMD 0.44 (0.11, 0.78, I²=82%)] and lower values for HDL [SMD -0.56 (-0.78, -0.34) I²=68%]. Conclusions. Even though the studies considered were observational, including mostly small samples, the evidence from this meta-analysis indicates women with PCOS from different regions of Brazil present worse cardiometabolic profile than women without PCOS. This systematic review and meta-analysis is registered in PROSPERO (CRD42016038537).
