Background: The prevalence of overweight and obesity among people with physical and intellectual disabilities is substantially higher than people without disabilities. As noted in the 2008 Physical Activity Guidelines for Americans, healthy weight is one of the major outcomes of regular physical activity. Methods: We conducted a comprehensive literature search to identify studies reporting the effects of physical activity on body composition in people with physical and intellectual disabilities. Results: Ten studies were identified, including 4 randomized controlled trials, 2 controlled trials without randomization, and 4 pre-post trials without a control group across five disability groups: intellectual disability (n=3), Down syndrome (n=2), stroke (n=2), spinal cord injury (n=1), and muscular dystrophy (n=1), and one study included six different disability groups. Results found limited evidence of an effect on reducing body weight in any of the disability groups (Mean Percent Loss [MPL]=.74%; Standardized Mean Difference Effect Size [SMD]=.08; 95% Confidence Interval [CI], -.14 to .3); body mass index (MPL=1.15%; SMD=.08; 95%CI, -.08 to .24); percent body fat (MPL =.53%; SMD=.05; 95%CI, -.3 to .4); skinfold thickness (MPL=9.5%; SMD=.25; 95%CI, -.11 to .62); and waist circumference (MPL =2.27%; SMD=.27; 95%CI, -.19 to .73). Conclusion: There is insufficient evidence to support the use of physical activity for reducing body weight/body fat in people with physical and intellectual disabilities. More research is needed to determine the effects of various doses (i.e., intensity, frequency, duration, type) of physical activity on weight loss in this population.

Learning Objectives:
Evaluate the current evidence on the effects of physical activity interventions in reducing body weight/fat in people with physical and cognitive disabilities.
