Neighborhood disorder and social cohesion: A longitudinal investigation of links with maternal cardiometabolic risk one year postpartum.

Objective: Neighborhood characteristics can influence cardiometabolic health, including during the perinatal period. However, maternal health research has largely examined the influence of objective neighborhood measures, limiting insights into psychological and social processes. We examined associations of perceived neighborhood disorder and social cohesion with maternal cardiometabolic risk 1 year postpartum and explored potential pathways of psychological distress and physical activity.

Methods: A predominantly low-income sample of Black, Latina, and White postpartum women (n = 987) were participants in the Community Child Health Network study. Women reported on neighborhood characteristics at 1 month postpartum and on symptoms of depression, anxiety, and posttraumatic stress disorder and physical activity at 6 months postpartum. Biometrics and biological samples were collected at 1 year postpartum, including blood pressure, height, weight, and dried blood spots for cardiometabolic biomarkers (e.g., C-reactive protein, glycosylated hemoglobin). In this pre-registered study, we used structural equation modeling to estimate latent variables for disorder, social cohesion, distress, physical activity, and cardiometabolic risk. We fit a parallel mediation model to test associations between latent neighborhood factors at 1 month postpartum, distress and physical activity at 6 months postpartum, and cardiometabolic risk at 1 year postpartum.

Results: Greater social cohesion, but not disorder, was significantly associated with lower distress and greater physical activity. However, there were no significant associations between disorder or social cohesion with subsequent cardiometabolic risk nor evidence for indirect effects of distress or physical activity.

Conclusion: Results suggest that social cohesion may be more pertinent than disorder for health-relevant behavioral mechanisms in postpartum women.
