背景感知邻里特征与肥胖有关，然而，这两个因素之间的联系机制仍然未知。目的本研究旨在检查感知邻里特征与体重指数（BMI）之间的关联，确定通过心理困扰和炎症的间接途径是否重要，并确定这些关联是否因种族/民族而异。112名成年人参加了德克萨斯州城市压力和健康研究。使用感知邻里量表测量感知邻里特征。采用流行病学研究中心抑郁量表、知觉压力量表和简明健康调查表中的心理健康子量表测量心理困扰。炎症标志物包括C-反应蛋白、白细胞介素-6和肿瘤坏死因子受体-1。结果通过直接和间接（即，心理困扰和炎症）路径显示出与数据的良好拟合。较不有利的感知邻居特征与更大的心理困扰（B =-0.87，beta =-0.31，p <0.001）和炎症（B =-0.02，beta =-0.10，p = 0.035）相关。心理困扰和炎症也与BMI显著相关（B-困扰= 0.06，β = 0.08，p = 0.006; B-炎症= 4.65，β = 0.41，p <0.001）。邻里特征通过心理困扰（B =-0.05，beta =-0.03，p = 0.004）和炎症（B =-0.08，beta =-0.04，p = 0.045）对BMI的间接路径是显著的。在多组分析中，一个模型的参数约束相等跨种族/种族显示出足够的拟合建议协会是跨groups. Conclusion可比的，我们的研究扩展了文献，通过展示的重要性，邻里的看法，跨种族/种族的BMI的相关性，并突出了心理和生理途径的作用。
Background Perceived neighborhood characteristics are linked to obesity, however, the mechanisms linking these two factors remain unknown.Purpose This study aimed to examine associations between perceived neighborhood characteristics and body mass index (BMI), establish whether indirect pathways through psychological distress and inflammation are important, and determine whether these associations vary by race/ethnicity.Methods Participants were 1,112 adults enrolled in the Texas City Stress and Health Study. Perceived neighborhood characteristics were measured using the Perceived Neighborhood Scale. Psychological distress was measured with the Center for Epidemiological Studies Depression Scale, Perceived Stress Scale and mental health subscale of the Short Form Health Survey-36. Markers of inflammation included C-reactive protein, interleukin-6, and tumor necrosis factor receptor-1. Associations were examined with Structural Equation Modeling.Results A model linking neighborhood characteristics with BMI through direct and indirect (i.e., psychological distress and inflammation) paths demonstrated good fit with the data. Less favorable perceived neighborhood characteristics were associated with greater psychological distress (B = -0.87, beta = -0.31, p < .001) and inflammation (B = -0.02, beta = -0.10, p = .035). Psychological distress and inflammation were also significantly associated with BMI (B-distress = 0.06, beta = 0.08, p = .006; B-inflammation = 4.65, beta = 0.41, p < .001). Indirect paths from neighborhood characteristics to BMI via psychological distress (B = -0.05, beta = -0.03, p = .004) and inflammation (B = -0.08, beta = -0.04, p = .045) were significant. In multiple group analysis, a model with parameters constrained equal across race/ethnicity showed adequate fit suggesting associations were comparable across groups.Conclusion Our study extends the literature by demonstrating the importance of neighborhood perceptions as correlates of BMI across race/ethnicity, and highlights the role of psychological and physiological pathways.
