目的：本研究旨在检查终身创伤（即，儿童期、成年期和累积）和体重指数（BMI），如果这种关联是由心理社会因素介导的（即，抑郁症状和压力）的非裔美国妇女的样本。研究方法：我们在遗传和心理因素对血压的代际影响研究（InterGEN）中研究了非洲裔美国妇女的终身创伤。我们用自助法进行了中介分析，以评估在整个生命周期中不断增加的创伤形式对BMI的直接和间接影响。抑郁症状和压力作为这些协会的调解人进行了检查。结果：分析样本包括138名女性，平均年龄为31.9岁。大约一半的妇女报告了任何童年创伤（47.8%），超过一半（73.2%）报告了任何成年创伤。所有形式的创伤的直接影响都与更严重的抑郁症状有关。只有终生创伤与较高的压力负荷相关（B=2.40，标准误[SE]=1.12，p<0.05）。在所有模型中，较高的抑郁症状与较高的BMI相关。成年期创伤（B=0.60，SE=0.20，p<0.01）和终生创伤（B=0.53，SE=0.20，p<0.01）对BMI的间接影响部分由抑郁症状介导。结论：这些发现表明，抑郁症状介导的成年和终身创伤与BMI之间的关联。旨在降低非裔美国妇女BMI升高的干预措施应考虑抑郁症状的影响。未来的研究应该在其他非裔美国妇女样本中复制这些分析。
Purpose: This study sought to examine the association between lifetime trauma (i.e., childhood, adulthood, and cumulative) and body mass index (BMI) and if this association was mediated by psychosocial factors (i.e., depressive symptoms and stress) in a sample of African American women. Methods: We examined lifetime trauma among African American women in the Intergenerational Impact of Genetic and Psychological Factors on Blood Pressure Study (InterGEN) study. We conducted mediation analyses with bootstrapping to assess the direct and indirect effects of increasing forms of trauma across the lifespan on BMI. Depressive symptoms and stress were examined as mediators of these associations. Results: The analytic sample included 138 women with a mean age of 31.9 years. Approximately half of women reported any childhood trauma (47.8%) and more than half (73.2%) reported any adulthood trauma. The direct effects of all forms of trauma were associated with greater depressive symptoms. Only lifetime trauma was associated with higher stress overload (B=2.40, standard error [SE]=1.12, p<0.05). Higher depressive symptoms were associated with higher BMI in all models. The indirect effects of adulthood trauma (B=0.60, SE=0.20, p<0.01) and lifetime trauma (B=0.53, SE=0.20, p<0.01) on BMI were partially mediated by depressive symptoms. Conclusion: These findings indicate that depressive symptoms mediate the associations between adulthood and lifetime trauma with BMI. Interventions aimed at reducing elevated BMI in African American women should account for the influence of depressive symptoms. Future research should replicate these analyses in other samples of African American women.
