Residential instability and obesity over time: The role of the social and built environment

This research uses the National Longitudinal Study of Adult Health׳s Obesity and Neighborhood Environment (ONE) to examine the relationship between residential instability and change in obesity in the United States. Mobility is thought to be related to obesity because it conditions what kinds of amenities are present in the areas where people live and what level of motivation individuals have to take advantage of these amenities. Thus, this research uses spatial measures as potential confounders for the mobility-health relationship. Results suggest that mobility is a protective factor against weight gain over time. However, the effect of mobility is completely explained by the environmental characteristics. After adjusting for changes in physical activity resources and the crime rate, adolescents who move and adolescents who do not move have precisely the same risk of being obese. Mobility is thus a function of the change in environmental characteristics. Implications for developing the built environment are discussed.
