Abstract

Metabolic syndrome (MetS) is a constellation of metabolic alteration related to abdominal obesity, inflammation and insulin resistance, which increase cardiovascular disease and mortality. The aims of the present study were to identify the prevalence of comorbidities and altered parameters in obese adolescents with and without MetS, and determine cut-off points of waist circumference to predict MetS. 195 obese adolescents were recruited and divided according to MetS diagnosis based on IDF criteria. Blood analyses of glucose, lipids, liver enzymes, adiponectin and leptin were measured. Insulin resistance was assessed by HOMA-IR, QUICKI and HOMA-AD. Visceral, subcutaneous and hepatic fat were ultrasonography obtained. Body composition was estimated by BOD POD system. We observed a prevalence of 25% of MetS (n=50). The MetS group presented significant higher body mass, BMI, body fat (kg), free-fat mass (kg), waist circumference, visceral fat, glucose, insulin, insulin resistance, total-cholesterol, LDL-c, VLDL-c, triglycerides, liver enzymes, non-alcoholic fatty liver disease (NAFLD) and blood pressure. Significant lower QUICKI and adiponectin in MetS group were noted. MetS girls presented significant higher leptin/adiponectin rat...Continue Reading
