Obesity in children is a major public health concern; in fact, 18.5 percent of children in the United States are considered obese. For autistic children, evidence suggests the percentage is even higher. Factors such as unusual dietary preferences, noncompliant behavior, decreased exercise, social isolation, and frequent use of psychotropic medication associated with weight gain may contribute to that higher percentage.
Through a two-year study funded by OAR in 2016, William Sharp, Ph.D., T. Lindsey Burrell, Ph.D., and Larry Scahill, Ph.D., principal investigators from the Marcus Autism Center in Atlanta, Ga., evaluated an intervention that targets obesity in autistic children to evaluate its acceptability, feasibility, and preliminary efficacy. The Changing Health in Autism through Nutrition, Getting Fit and Expanding Variety (CHANGE) program is a multidisciplinary, manual-based intervention that combines behavioral intervention and nutrition education to address each child’s unique behavioral, feeding, and nutritional profile. CHANGE uses a “parent as co-therapist” model designed for cost-efficiency and flexible usage. The manual includes methods to increase dietary diversity and reduce grazing between meals/intake of sweetened beverages, as well as in-clinic activities and homework assignments to promote physical activity.
For the study, the research team enrolled seven children between the ages of 5 and 12, along with a parent/caregiver, to participate in 16 sessions over six months with a therapist who delivered the intervention and worked with the parents. The initial 10 sessions were delivered weekly, followed by six booster sessions to support continued progress. The researchers’ goals were to:
While none of the participants experienced significant weight loss during the research study, there was improvement in:
Overall, caregivers were satisfied with the intervention, based on a score of four out of five regarding treatment acceptability. Therapists delivered the intervention with high integrity (80 percent or greater).
These results provide provisional evidence to support continued study of the CHANGE program, including determining the long-term sustainability and impact of the observed healthy lifestyle changes.
