A call for obesity prevention interventions for young children with intellectual and developmental disabilities.

Health disparities among children with intellectual and developmental disabilities (IDD) are present in early childhood. Yet, this population is underrepresented in health behavior research. In this commentary the authors highlight the need for multi-level physical activity and nutrition research for obesity prevention with a specific focus on young children with Down syndrome, a population at greater risk of developing overweight and obesity compared to typically developing peers. This commentary describes the comorbidities and developmental challenges faced by many children with Down syndrome which may influence weight-related physical activity and nutrition behaviors. Additionally, the authors advocate for involving a multidisciplinary team of experts to inform the adaptation or development of multi-level, theory-driven behavioral interventions to prevent obesity among children with Down syndrome.
