Gender-Specific Predictive Utility of Twelve Anthropometric Indices for Metabolic Syndrome in Chinese Lahu Adults with Dyslipidemia

Objective: To evaluate the gender-specific predictive performance of 12 anthropometric indices for metabolic syndrome (MetS) among Lahu ethnic adults with dyslipidemia. Methods: This cross-sectional study employed stratified cluster sampling in two Lahu communities in southwest China. MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATPIII) criteria. Twelve indices were assessed: body mass index (BMI), waist circumference (WC), lipid accumulation product (LAP), visceral adiposity index (VAI), a body shape index (ABSI), body adiposity index (BAI), body roundness index (BRI), relative fat mass (RFM), uric acid-to-HDL-C ratio (UHR), triglyceride-glucose index (TyG), cardiometabolic index (CMI), and Chinese visceral adiposity index (CVAI). Receiver operating characteristic (ROC) curve analysis evaluated predictive performance, and binary logistic regression assessed associations with MetS and its components. Results: This study of 1257 Lahu adults with dyslipidemia (48.5% male) revealed a 23.4% MetS prevalence, significantly higher in females (29.2% vs 17.2%, p
