Objectives:To examine the associations between neighborhood environment-perceived neighborhood social cohesion and perceived neighborhood physical environment-and physical activity (PA) and whether these associations differ by race/ethnicity. Methods: We analyzed data from the Health and Retirement Study, a longitudinal study of US adults aged 50+ from 2006 to 2014 (N = 17,974), using multivariate mixed-effects linear models. PA was repeatedly measured using metabolic equivalent of task estimated values accounting for the vigor and frequency of self-reported PA. Results: In multivariate models, higher levels of PA were positively associated with higher rated neighborhood social cohesion and neighborhood physical environment scores. The effects of social cohesion were stronger among non-Hispanic Whites than among non-Hispanic Black and Hispanic/Latinx participants, while race/ethnicity did not moderate the association between PA and physical environment. Discussion: Intervention strategies that address social and physical barriers of neighborhoods could promote PA in older adults. Key implications for future research are discussed.
