The built environment and obesity among low-income preschool children.

In spite of the evidence that adult obesity is influenced by environmental factors, the influence of the environment on childhood obesity remains under-investigated. This paper examines the association of the built environment with the prevalence of obesity in low-income preschool children. Built environment indicators include measures relating to food choice and physical activity. The relationship of the environment with childhood obesity is further stratified by urban-rural location. Overall, the built environment is associated with the prevalence of obesity in low-income preschool children, although the impact of the environment is affected by urban-rural status. Results imply broad-scope for community-level interventions.
