title: Metabolic syndrome among prepubertal Brazilian schoolchildren.
abstract: This was a two-stage cross-sectional study that assessed metabolic syndrome and associated factors among prepubertal schoolchildren. In the first stage, nutritional status, blood pressure, personal (low birth weight) and family antecedents for cardiovascular disease (CVD) were collected. In the second stage, schoolchildren with at least one of these criteria participated: obesity, personal or family history. Metabolic syndrome (MS) was defined by ATP III and WHO definitions. Among 929 (6-10 year old) schoolchildren, 27.7% presented with overweight/obesity, 12.2% hypertension, and personal (9.4%) and family (35.3%) antecedents. 205 children finished the second stage. The frequencies of MS-ATP and MS-WHO were 9.3% and 1.9%. Among the obese, MS was present in 25.8% (ATP) and 5.2% (WHO). Children with normal weight presented: low HDL (23.6%), hyperglycaemia (3.6%), HOMA-IR (0.9%) and MS-ATP (0.9%). In conclusion, overweight/obesity was associated with metabolic syndrome in schoolchildren. It was found that children with normal weight with personal and/or family antecedents presented with HOMA-IR and MS-ATP.
