Background: Polycystic ovary syndrome (PCOS) affects up to 15% of women and is associated with a multitude of metabolic complications including insulin resistance, type 2 diabetes, cardiovascular disease, and hepatic steatosis. In the general population, metabolic disease rates vary by race and ethnicity. The interaction of race and ethnicity with PCOS-related metabolic disease in adolescent youth has not been extensively examined. Methods: Secondary analysis of data from overweight and obese (&amp;gt;90 BMI%ile) adolescent (12-21 years) female participants with PCOS enrolled across 4 protocols. Measurements included fasting hormone and metabolic measures, a 2-hour oral glucose tolerance test and MRI for hepatic fat. Groups were compared by ANOVA, with and without correction for BMI or chi-square tests for proportions. Results: Participants included 39 white (NHW 15.7±0.2 years; 97.7±0.2 BMI%ile), 50 Hispanic (15.2±0.3 years; 97.9±0.3 BMI%ile) and 12 black (NHB 16.0±0.6 years; 98.6±0.4 BMI%ile) adolescents. BMI%ile was different between groups (p=0.04), but age of menarche, free testosterone and hirsutism severity were not. Hepatic markers of insulin resistance were worse in Hispanic youth, including lower sex hormone binding globulin and TG/HDL ratio (p&amp;lt;0.001), although HOMA-IR was worst in NHB (p=0.009) and Hispanic (p=0.036) compared to NHW youth. There were no significant differences in insulin concentrations—either fasting or during the OGTT—although fasting C-peptide was higher in Hispanic (p=0.008) compared to NHW youth. Fasting and 2-hour glucose concentrations were not different between groups. HbA1c was highest in NHB (5.7±0.4%, p&amp;lt;0.001 vs. NHW, p=0.026 vs. Hispanic), then Hispanic (5.5±0.3, p&amp;lt;0.001 vs. NHW), then NHW (5.2±0.3) youth. Fasting triglycerides differed between groups (p=0.029), being highest in Hispanic youth (129 [105,167] mg/dL). The frequency of hepatic steatosis (NHW 42%, Hispanic 62% NHB 25%, p=0.032) and the metabolic syndrome components HDL &amp;lt;40 mg/dL (NHW 61%, Hispanic 82% NHB 50%, p&amp;lt;0.001) and HbA1c 5.7-6.4% (NHW 5%, Hispanic 36% NHB 50%, p&amp;lt;0.001) were different between the groups. Conclusions: Adolescents with PCOS appear to show similar racial and ethnic variation to the general population in terms of metabolic disease components.
