目的：目前的研究检查了社会心理因素对社会经济地位（SES）和代谢综合征（MetSyn）风险之间的关联的贡献，在随机选择的304名中年（40-65岁）墨西哥裔美国妇女的社区队列中，这是一个心脏代谢风险升高的人群。方法：参与者接受了临床检查和人口统计学因素和心理社会资源（即，个人和社会资源）和风险（即，负面情绪和认知）变量。在总样本中以及在更多和更少的美国人中进行了验证性因素分析（CFA）和结构方程模型（SEM）。文化适应的妇女（由语言偏好定义）分别。结果：CFA揭示了SES的单一潜在结构（即，收入、教育）和心理社会资源/风险。确定了三因素解决方案，血压（收缩压和舒张压）、脂质（高密度脂蛋白胆固醇甘油三酯）和代谢变量（葡萄糖腰围）形成单独的因素。SEM显示，SES通过心理社会资源/风险与MetSyn因素相关的间接效应模型在完整和更适应的样本中提供了合理的描述和统计拟合（近似均方根误差[RMSEA]和标准化均方根残差< .08）;根据RMSEA = .09，在较少适应的样本中拟合是边缘的。在总体和文化适应程度较高的样本中，通过较低的心理社会资源/较高的心理社会风险，确定了从低SES到较高腰围/空腹血糖的显著介导路径（p <0.05）。结论：在这个健康的中年墨西哥裔美国妇女队列中，社会心理因素对SES MetSyn协会的贡献仅限于核心的潜在代谢机制，而更多的是美国人。文化适应的女性。
Objectives: The current study examined the contributions of psychosocial factors to the association between socioeconomic status (SES) and metabolic syndrome (MetSyn) risk, in a randomly selected community cohort of 304 middle-aged (40-65 years old) Mexican-American women, a population at elevated cardiometabolic risk. Methods: Participants underwent a clinical exam and measures of demographic factors and psychosocial resource (i.e., personal and social resources) and risk (i.e., negative emotions and cognitions) variables. Confirmatory factor analysis (CFA) and structural equation models (SEMs) were performed in the total sample and in more- and less-U.S.-acculturated women (defined by language preference) separately. Results: CFAs revealed single latent constructs for SES (i.e., income, education) and psychosocial resources/risk. Three-factor solution was identified, with blood pressure (systolic diastolic), lipids (high-density lipoprotein cholesterol triglycerides), and metabolic variables (glucose waist circumference) forming separate factors. SEMs showed that an indirect effects model with SES relating to MetSyn factors through psychosocial resources/risk provided a reasonable descriptive and statistical fit in the full and more-acculturated sample (root mean square error of approximation [RMSEA] and standardized root-mean-square residual < .08); fit in the less-acculturated sample was marginal according to RMSEA = .09. A significant mediated path from low SES to higher waist circumference/fasting glucose via lower psychosocial resources/higher psychosocial risk was identified in the overall and more-acculturated samples (p < .05). Conclusions: In this cohort of healthy, middle-aged Mexican-American women, contributions of psychosocial factors to SES MetSyn associations were limited to the core underlying metabolic mechanisms, and to more-U.S.-acculturated women.
