ABSTRACT
Background: Our aim was to evaluate the association of metabolic syndrome [MetS] and its components with body fat percentage [BFP] and anthropometric indicesin10 to 18year old adolescents
Methods: This was a cross-sectional study conducted on 134 Tehranian adolescents, aged 10 to 18 years [66 boys and 68 girls] in 2007. The MetS definition proposed by Cook et al. was used. Logistic regression was used to determine the relationship of MetS and its components with body mass index [BMI], waist circumference [WC], waist to height ratio [WHtR], and BFP. Using the areas under the receiver operating characteristic [ROC] curve, the discriminatory ability of anthropometric measurements and BFP was evaluated
Results: The mean+/-SD forage of boys and girls was14.5+/-2.3and13.0+/-2.9 years, respectively [P=0.001]; the prevalence of MetS in these groups was 32.3 and6.5%, respectively [P=0.001]. After adjusting for sex and physical activity, the highest odds ratios [95% CI] for MetS and hypertriglyceridemia were found for WC, 6.27 [2.63-14.94; P<0.05] and 3.14 [1.87-5.27; P<0.05], respectively, and those for low HDL-C and hypertension were found for BMI, 2.91 [1.73-4.90; P<0.05] and 2.26 [1.27-4.02; P=0.05], respectively. After adjusting for sex and physical activity, the highest area under ROC curve for MetS and hypertriglyceridemia was seen for WC [P=0.001], for hypertension it was seen for BMI [P=0.001], and for low HDL-C it was observed for both WC and BMI [P=0.001]
Conclusions: In adolescents, WC was the best predictor of MetS and hypertriglyceridemia, BMI was the best predictor of hypertension, and WC and BMI were the best predictors for low HDL-C
