This is a multicenter pilot in a sample of children and adolescents 3-17 years of age. Is planned to developing it in Sao Paulo and six other cities in South America: Teresina (Brazil), Buenos Aires (Argentina), Santiago (Chile), Montevideo (Uruguay), Lima (Peru) and Medellin (Colombia). The training for evaluators and the design will be standardized and the same methodology will be applied.

Several analyzes will be performed, including: descriptive include calculating the mean, standard deviation, percentage and confidence interval of 95 %. The agreements between measurements were calculated by determining the kappa coefficients for categorical variables and intra class correlation coefficients for quantitative variables. The latter will be complemented by the development of Bland- Altman. Calculated the correlation between the different methods by Spearman correlation coefficients (nonparametric) and Pearson (parametric). (AU)
