Summary

Recent literature reviews showed that overweight and obesity represent a major health threat in adults with intellectual disability (ID). However, the current evidence around the prevalence and risk factors associated with overweight and obesity in children and adolescents with ID remains unclear. The objective of this article was thus to review the available English- and French-language studies examining the prevalence and risk factors associated with overweight and obesity in youths with ID. Ten studies providing original data on this topic were identified and included in this review. Results demonstrated that (i) overweight and obesity represent a significant secondary health problem in youths with ID; and (ii) obesity risk significantly increases with age. Considering all of the limitations of the reviewed studies (i.e. heterogeneity in sample size and in overweight and obesity classification criteria; lack of comparison group; restrictive number of risk factors examined, etc.), these findings remain preliminary and highlight the need for future research in this area.
