Objective. The aim of this study is to examine a relationship between neighborhood-level socioeconomic deprivation and weight change in a multi-ethnic cohort from Dallas County, Texas and whether behavioral/psychosocial factors attenuate the relationship. %26lt;br%26gt;Methods. Non-movers (those in the same neighborhood throughout the study period) aged 18-65 (N = 939) in Dallas Heart Study (DHS) underwent weight measurements between 2000 and 2009 (median 7-year follow-up). Geocoded home addresses defined block groups; a neighborhood deprivation index (NDI) was created (higher NDI = greater deprivation). Multi-level modeling determined weight change relative to NDI. Model fit improvement was examined with adding physical activity and neighborhood environment perceptions (higher score = more unfavorable perceptions) as covariates. A significant interaction between residence length and NDI was found (p-interaction = 0.04); results were stratified by median residence length (11 years). %26lt;br%26gt;Results. Adjusting for age, sex, race/ethnicity, smoking, and education/income, those who lived in neighborhood %26gt; 11 years gained 1.0 kg per one-unit increment of NDI (p = 0.03), or 6 kg for those in highest NDI tertile compared with those in the lowest tertile. Physical activity improved model fit; NDI remained associated with weight gain after adjustment for physical activity and neighborhood environment perceptions. There was no significant relationship between NDI and weight change for those in their neighborhood %26lt;= 11 years. %26lt;br%26gt;Conclusions. Living in more socioeconomically deprived neighborhoods over a longer time period was associated with weight gain in DHS. Published by Elsevier Inc.
