Aim: To examine the relation between adiposity assessment methods (percentage body fat (�), BMI, and waist circumference (WC)) and individual metabolic risk factors (f-insulin, HDL cholesterol, triglycerides) and a combined measure of metabolic risk. Methods: Cross-sectional study of 300 males (BMI 20.8 /- 3.0 kg/m(2)) and females (BMI 21.3 /- 2.9 kg/m(2)) 17 years of age. F-insulin and components of the metabolic syndrome defined by the International Diabetes Federation (IDF) were used as metabolic risk indicators, with samples stratified into BMI, �, and WC groups, respectively. Diagnostic accuracy was expressed as the area under the ROC curve (AUC). Results: In males, diagnostic accuracy for HDL and f-insulin was poor to fair for BMI (AUC 0.70, p = 0.001; 0.60, p = 0.22), WC (0.68, p = 0.003; 0.63, p = 0.11), and � (0.65, p = 0.009; 0.66, p = 0.04). The diagnostic accuracy for triglycerides was greater for all three measures (BMI 0.92, WC 0.95, � 0.87; all p < 0.001). For females, neither test performed better than chance for f-insulin and HDL, and only � performed better than chance for triglycerides (0.65, p = 0.08). All three measures exhibited higher accuracy for presence of >= 2 metabolic risk factors (AUCs 0.76-0.91, p < 0.001) in both sexes. Conclusion: � was not superior to BMI and WC for detecting metabolic risk in the general adolescent population.
