Growth disorders and obesity in youth are public health problem. Youth with intellectual disabilities (ID) have higher prevalence of obesity and growth disorders than the general population of youth without ID. In Brazil, there are no population-based research about growth and body composition in youth with ID. The primary objective of this study is to examine the patterns and determinants of growth and overweight in Brazilian youth with ID. The secondary objective is to examine the body composition and its potential determinants in youth with and without ID; the accuracy of anthropometric data in detecting overweight in youth with ID will also be examined. To achieve the primary objective, we will include the anthropometric variables (i.e. weight, height, and body circumferences) of youth with ID. To achieve the secondary objective, we will include anthropometric variables and DXA body composition data (percentage of fat, regional and total fat and lean mass, and bone variables) and its potential determinants (physical activity levels, sedentary behavior, sports participation, motor performance, sexual maturation, quality of sleep, eating patterns, comorbidities and sociodemographic factors) of youth with and without ID. This study is crucial to support clinical practice and epidemiological research to guide public policy in preventing growth disorders and reducing obesity in youth with ID.
