Obesity prevention for children with physical disabilities: a scoping review of physical activity and nutrition interventions

Purpose: Children with disabilities are at higher risk of obesity, engage in less physical activity and report poorer quality dietary habits than their non-disabled peers. This study reviewed current evidence on interventions designed to facilitate weight management and/or weight-related behaviors (i.e. physical activity and/or healthy eating habits) in children with physical disabilities. Methods: A scoping review was performed using established methodology. Data from studies meeting specific inclusion criteria were extracted and analyzed using summary statistics, and common characteristics thematically identified. Results: Thirty-four articles were included in the synthesis. No long-term obesity prevention interventions were identified. The majority of research focused upon children with cerebral palsy, and had case study, quasi-or non-experimental designs. All interventions reporting positive outcomes (n = 18) addressed physical activity, with common themes including using motivational strategies for the child and child self-direction. Incremental increases in workload and engaging in strength training for longer than 15 minutes were also effective. Interventions targeting body weight/composition did not report success in the long term. Conclusions: A robust evidence base is lacking for long-lasting obesity interventions for children with physical disabilities. Current research provides some insights into the specific components that should be considered when planning such interventions in the future.
