Neighborhood Cohesion, Disorder, and Physical Function in Older Adults: An Examination of Racial/Ethnic Differences

Objectives: This study examined the link between neighborhood social cohesion, disorder, and physical function in older adults, and identified potential racial/ethnic differences in these associations. Method: Data come from the National Health and Aging Trends Study (NHATS; N = 5,619). A series of linear regression models were used to predict physical function. Subgroup analyses and neighborhood/race interactions were used to examine differences. Results: Neighborhood disorder was associated with poorer physical function (p < .05), while neighborhood cohesion was not (p = .06). Although tests of interactions were not significant, subgroup analyses showed that neighborhood disorder, and not social cohesion, was associated with poorer physical function only in Whites. Discussion: Disadvantaged neighborhood social environment may contribute to differences in physical function among older adults. Racial and ethnic differences warrant closer investigation in studies of neighborhoods and functional health.
