Background: Research suggests the built environment can influence child activity and eating. Purpose: Test whether the built environment is related to effectiveness of standardized family-based behavioral treatments on overweight children’s weight loss. Method: zBMI changes for 212 children (8-12 years old) who participated in four randomized trials to treat obesity were related to built environment related to physical activity or food purchasing. Results: Parkland, larger average block size and fewer supermarkets were associated with greater zBMI change at 2 years. Girls and older children with low access to convenience stores had better success at 2 years, while interactions of no parkland with low block size, high number of supermarkets or convenience stores were related to reduced long-term zBMI change. Conclusions: Built environment is associated with child success in behavioral treatments for obesity, and efficacy may be improved by individualizing treatments based on characteristics of the built environment.
