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.
目的
邻里特征会影响心脏代谢健康，包括在围产期。然而，孕产妇健康研究大多考察的是客观邻里指标的影响，限制了对心理和社会过程的洞察。我们研究了产后1年时感知到的邻里失序和社会凝聚力与孕产妇心脏代谢风险之间的关联，并探索了心理困扰和身体活动的潜在途径。
方法
以黑人、拉丁裔和白人产后女性为主的低收入样本（n = 987）参与了社区儿童健康网络研究。女性在产后1个月报告邻里特征，在产后6个月报告抑郁、焦虑和创伤后应激障碍症状以及身体活动情况。在产后1年收集生物特征和生物样本，包括血压、身高、体重以及用于心脏代谢生物标志物（如C反应蛋白、糖化血红蛋白）的干血斑。在这项预先注册的研究中，我们使用结构方程模型来估计失序、社会凝聚力、困扰、身体活动和心脏代谢风险的潜在变量。我们拟合了一个平行中介模型，以检验产后1个月时潜在邻里因素与产后6个月时的困扰和身体活动以及产后1年时的心脏代谢风险之间的关联。
结果
更高的社会凝聚力而非失序，与更低的困扰和更多的身体活动显著相关。然而，失序或社会凝聚力与随后的心脏代谢风险之间没有显著关联，也没有证据表明困扰或身体活动存在间接影响。
结论
结果表明，对于产后女性与健康相关的行为机制，社会凝聚力可能比失序更相关。
