Obesity is more prevalent in adults with intellectual disabilities than in the general population, and has been shown to contribute to their reduced life expectancy, and increased health needs. Relatively few studies have examined the effectiveness of weight loss interventions for adults with intellectual disabilities. However, there is evidence to support interventions that take account of the context of the lives of adults with intellectual disabilities, including carer involvement in interventions. To reduce the health inequalities experienced by adults with intellectual disabilities, there is a clear need to develop accessible, evidence-based clinical weight management services.
