RESUMO

Objctive. To assess the nutrional status of schoolchildren from 7 to 10 years of age. Methods. Cross-sectional study in two public schools in the southeastern region of the city of Sao Paulo. Weight, height, arm and waist circunference (WC), skinfold thickness (triceps and calf), bioelectrical impedance (BIA) and derived indices and measurements ( upper arm and fat area (AFA), percentage of the bofy fat (% BF), body mass index (BMI) and height to age index were used. The nutritional status was assessed by BMI percentile using CDC 2000 curve. The data was presented in tables and graphics; comparisons were carried out by 95% confidence intervals, median values and Bland and Altman analysis. The performamces of measures of body composition to identify inadequate nutritional status and cut-off values were studied based on ROC and TGROC curves. Results. The foolowing prevalences were observed: underweight, 4.5%, risk of overweight, 15.3% and overweight 11.0%. The median of the anthropometric measurements and body composition were greater than in previous studies. The percentage of fat values depends on the method used for its estimation. Skinfold thickness presents better performance than BIA ti identify excess of weight when BMI was taken as a reference method. WC and AFA showed good performance to identify risk of cardiovascular diseases. Conclusions. Schoolchildren from 7 to 10 years of age present high levels of body fat reserve. These conditions indicate the need for health interventions.
