This research project is part of multicenter South American Youth / child Cardiovascular and Environment Study (SAYCARE study). This is an observational feasibility study that will evaluate a sub-sample of 474 children and adolescents (3-17 years). The subjects were selected in public and private schools in five South American cities: Buenos Aires (Argentina), Lima (Peru), Medellín (Colombia), São Paulo and Teresina (Brazil). The main objective will be to evaluate the construct validity of the evaluation methods for diagnostic criteria of the double burden of malnutrition (DBM) among South American children and adolescents in predicting the ideal cardiovascular health. The significance criterion will be an ± of 5%. For the descriptive analysis in the presentation of categorical / continuous variables will be included proportion, mean, standard deviation and 95% confidence interval. Being stratified by sex, research center and socioeconomic variables. In order to test the construct validity of the different diagnostic criteria of DBM, predictive values of sensitivity and specificity, and positive and negative values will be calculated through the 2x2 contingency table. The diagnostic criteria for double burden of malnutrition will be estimated by the ROC (Receive Operator Characteristic) curve. Key words: double burden, malnutrition, diagnostic criteria, obesity, nutritional transition, pediatrics, multicenter study.
