[Body Mass Index, Waist Circumference and skinfolds for predicting lipid abnormalities in 11 years old children].
OBJECTIVE
To analyze the predictive capacity of Body Mass Index (BMI), Waist Circumference (WC) and Triceps Skin Folds (TSF) to diagnose of lipid abnormalities and to suggest cutoff points for these measures in order to identify this disease in children.


METHODS
It was measured the BMI, WC, TSF and lipid profiles of 374 schoolchildren (11,25 +/- 0,28 years) from the public education system of Santa Maria, RS, Brazil. Area under the ROC curve (95%CI), sensitivity, specificity and predictive values were analyzed in order to identify the ideal cutoff points.


RESULTS
The anthropometric variables only exhibited diagnostic capacity for TG among the girls and CT and LDL-C for the boys.


CONCLUSIONS
It was concluded that a BMI of 19.3 kg/m(2) is a diagnostic value for abnormal TG levels in females and for abnormal CT and LDL-C among males. Elevated concentrations of CT and LDL-C can also be diagnosed in boys using cut-off values of WC > 65.7 cm and TSF > 21.0mm.
