Cross-sectional and longitudinal associations of neighborhood cohesion and stressors with depressive symptoms in the multiethnic study of atherosclerosis.
OBJECTIVE
This study examined associations of neighborhood social cohesion, violence, and aesthetic quality with depressive symptoms among 2,619 healthy adults aged 45-84 years enrolled in the Multiethnic Study of Atherosclerosis.


METHODS
Neighborhood characteristics were estimated by surveying a separate sample of area residents. Measures of aesthetic environment, social cohesion, and violence were combined into a summary score with increasing scores indicating more favorable environments. Depressive symptoms were measured using the Center for Epidemiologic Studies-Depression (CES-D) scale. Marginal maximum likelihood estimation was used to assess associations of neighborhood characteristics with CES-D score at baseline and with the odds of developing incident depression (CES-D score >/=16 or use of antidepressants) over a 4-5 year follow-up among persons with CES-D less than 16 at baseline. Models were adjusted for age, income, education, and race/ethnicity.


RESULTS
Lower levels of social cohesion and aesthetic quality and higher levels of violence were associated with higher mean CES-D scores in men and women (P for trend <0.01, adjusted mean difference in CES-D per 1 SD increase in summary score -1.01 [95% confidence interval = -1.85, -0.17] and -1.08 [95% confidence interval = -1.88, -0.28] in men and women, respectively). Associations of neighborhood characteristics with incident depression were in the expected direction for women but confidence intervals were wide (odds ratio of incident depression = 0.89 [0.63, 1.26]). No association was seen for men (odds ratio = 0.96 [0.74, 1.25]).


CONCLUSIONS
Neighborhood social cohesion, aesthetic quality, and violence are associated with the presence of depressive symptoms in residents.
