Neighborhood social cohesion and posttraumatic stress disorder in a community-based sample: findings from the Detroit Neighborhood Health Study.

ABSTRACT:

Purpose

Posttraumatic stress disorder (PTSD) is common and debilitating. Although research has identified individual-level risk factors for PTSD, the role of macro-social factors in PTSD etiology remains unknown. This study tests whether perceived neighborhood social cohesion (NSC), measured at the both the individual and neighborhood levels, plays a role in determining past-year risk of PTSD among those exposed to trauma.

Methods

Data (n = 1,221) were obtained from an ongoing prospective epidemiologic study in the city of Detroit. Assessment of traumatic event exposure and PTSD was consistent with DSM-IV criteria. Generalized estimating equations (GEE) and logistic regression models were used to estimate the association of neighborhood-level perceived NSC with the risk of PTSD, adjusting for individual-level perceptions of NSC and other covariates.

Results

The odds of past-year PTSD were significantly higher among those residing in a neighborhood with low social cohesion compared to high (OR = 2.44, 95 % CI: 1.58, 3.78), independent of individual sociodemographic characteristics, number of traumas, and individual-level perceptions of NSC. The odds of past-year PTSD were not significantly associated with individual-level perceptions of NSC.

Conclusions

These results demonstrate that social context shapes risk of PTSD and suggest that changing the social context may shift vulnerability to this disorder.

Project description:BackgroundNeighborhood factors of social isolation have been understudied, hindering efforts to reduce social isolation at the neighborhood level. This study aims to investigate the longitudinal effects of neighborhood social cohesion and physical disorder on social isolation in community-dwelling older adults, as well as to examine whether race/ethnicity moderates the neighborhood-isolation relationship.MethodsWe used 11-year data from the National Health and Aging Trend Study, a longitudinal national study of Medicare beneficiaries aged 65 and older. Social isolation was measured through a summary score across four domains: marital/partner status, family and friend contact, religious attendance, and club participation. A series of weighted mixed-effects logistic regression models were performed to test the study aims. Sample sizes ranged from 7,303 to 7,291 across individual domains of social isolation.ResultsApproximately 20% of participants reported social isolation. Findings indicated a negative association between neighborhood social cohesion and social isolation. Higher levels of neighborhood social cohesion were longitudinally associated with lower odds of social isolation (odds ratio [OR] = 0.52, 95% CI: 0.47-0.58). Yet, the presence of neighborhood physical disorder was associated with an increased risk of overall social isolation ([OR] = 1.2, 95% CI: 1.00, 1.44). Race/ethnicity significantly moderated the effects of neighborhood social cohesion and physical disorder on social isolation. The odds of no in-person visits associated with neighborhood social cohesion are smaller among Black adults compared to White adults. Black adults had constantly lower odds of isolation from religious attendance compared to White adults regardless of the level of neighborhood social cohesion. Hispanic adults had decreased odds of having no friends associated with signs of physical disorder, while no associations were found among older White adults. White adults had higher odds of isolation from in-person visits when living in neighborhoods with signs of physical disorder, whereas no association was observed among older Black and Hispanic adults.ConclusionsThis study elucidates the role of neighborhood characteristics in shaping social isolation dynamics among older adults. Furthermore, the observed moderation effects of race/ethnicity suggest the need for culturally sensitive interventions tailored to address social isolation within specific neighborhood and racial contexts.

Project description:BackgroundNeighborhood social cohesion (NSC) is the network of relationships as well as the shared values and norms of residents in a neighborhood. Higher NSC has been associated with improved cardiovascular health, largely among Whites but not African Americans. In a bi-racial cohort, we aimed to study the association between NSC and chronic disease awareness and engagement in healthy self-management behaviors, two potential mechanisms by which NSC could impact cardiovascular health outcomes.MethodsUsing the Healthy Aging in Neighborhoods of Diversity Across the Lifespan Study (HANDLS), we cross-sectionally examined the association between NSC and awareness of three chronic conditions (diabetes, chronic kidney disease (CKD), and hypertension) and engagement in healthy self-management behaviors including physical activity, healthy eating, and cigarette avoidance.ResultsStudy participants (n = 2082) had a mean age of 56.5 years; 38.7% were White and 61.4% African American. Of the participants, 26% had diabetes, 70% had hypertension and 20.2% had CKD. Mean NSC was 3.3 (SD = 0.80) on a scale of 1 (lowest score) to 5 (highest score). There was no significant association between NSC and any chronic disease awareness, overall or by race. However, each higher point in mean NSC score was associated with less cigarette use and healthier eating scores, among Whites (adjusted odds ratio [aOR], 95% confidence interval [CI]: =0.76, 0.61-0.94; beta coefficient [βc]:, 95% CI: 1.75; 0.55-2.97, respectively) but not African Americans (aOR = 0.95, 0.79-1.13; βc: 0.46, - 0.48-1.39, respectively; Pinteraction = 0.08 and 0.06). Among both Whites and African Americans, higher NSC scores were associated with increases in self-reported physical activity (βc: 0.12; 0.08-0.16; Pinteraction = 0.40).ConclusionsCommunity engagement and neighborhood social cohesion may be important targets for promotion of healthy behaviors and cardiovascular disease prevention. More research is needed to understand the different associations of NSC and healthy behaviors by race.
