Associations between neighborhood built environment, residential property values, and adult BMI change: The Seattle Obesity Study III

•Strong, inverse cross-sectional relationships between the built environment, residential property values (a proxy for individual socioeconomic status), and measured BMI were observed.•Measures of the built environment and residential property values showed modest and inconsistent associations with 1- and 2-year BMI change.•There was suggestive evidence that age may moderate the association between urban density and 1- and 2-year BMI change while education may moderate the association between residential property values and 2-year BMI change.
