Approximately 4.5 million Americans have an intellectual or developmental disability. Concern is increasing about these individuals' nutrition-related behavior and its implications for their health. This article reports on a systematic search of the current literature listed in the PsycINFO and PubMed databases related to nutritional status of adults with intellectual or developmental disabilities. The authors used key terms for nutrition, secondary conditions, and intellectual and developmental disability and categorized literature pertaining to nutrition-related studies of adults with intellectual or developmental disabilities as follows: dietary intake studies, anthropometric assessments of nutritional risks, biochemical indexes, and clinical evaluations.

Findings suggest that residents with intellectual disabilities have low physical activity and opportunities for participation. Key attributes of the group home setting were identified between barriers and facilitators to activity. Consideration for the development of physical activity programmes should focus on the unique needs of the group home setting as expressed by stakeholders. Implications for rehabilitation Physical activity can improve physical fitness, function, and community participation yet physical activity remains low among adults with intellectual disabilities. Understanding physical activity within the group home setting is essential to develop targeted interventions to increase activity within that environment. Key barriers for physical activity within the group home setting include; operational priorities, limited staff, staff turnover, busy schedules, and staff attitudes towards physical activity.
