Neighborhood social environments are well-known to support or hinder PA among older adults, but their associations with PA among persons living with dementia remain poorly understood. This study examines how neighborhood characteristics (affluence, deprivation, safety, friends, relatives, cohesion, and disorder) relate to PA among U.S. community-dwelling persons living with dementia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Research Design and Methods<\/jats:title>\n                    <jats:p>We used 2006\u20132018 Health and Retirement Study data merged with census-tract data from the Contextual Data Resource. The analytic sample included 2,031 respondents classified as having dementia. PA was measured as a summary score reflecting activity frequency and intensity (light, moderate, and vigorous), along with binary indicators for being \u201cregularly active\u201d (\u22651\u00d7\/week) at each intensity. We used negative binomial regression to model total PA and logistic regression for intensity-specific activity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Neighborhood friendships were associated with higher overall PA score (B\u2009=\u20090.28; 95% CI\u2009=\u20090.16\u20130.41) and regular engagement across intensity levels. Social cohesion was also linked to increased total activity (B\u2009=\u20090.16; 95% CI\u2009=\u20090.03\u20130.29) and light PA (OR\u2009=\u20091.31; 95% CI\u2009=\u20091.01\u20131.71). Affluent neighborhoods supported moderate PA (OR\u2009=\u20091.39; 95% CI\u2009=\u20091.08\u20131.77), while having nearby relatives was associated with lower odds of vigorous activity (OR\u2009=\u20090.61; 95% CI\u2009=\u20090.42\u20130.88).
