该研究的目的是通过超重或肥胖的非裔美国人的心理和环境介导因素来研究社会经济地位和饮食行为之间的关系。我们在225名非洲裔美国男性和女性中进行了一项横断面研究。数据进行了分析，使用结构方程模型与自举程序。在多重中介模型中，社会经济地位通过心理和环境因素对饮食行为有显著的间接影响（β=-0.27，p= 0.01，95%置信区间[CI]=-0.59至0.10），但对饮食行为没有显著的直接影响（β= 0.06，p= 0.70，95% CI=-0.21至0.39）。社会经济地位对心理因素（β= 0.52，p= 0.01，95%CI =0.31 ~ 0.77）和环境因素（β=-0.40，p= 0.03，95%CI =-0.53 ~-0.25）有显著的直接影响。心理因素（β=-0.31，p= 0.02，95%CI =-0.68至-0.04）和环境因素（β= 0.26，p= 0.01，95%CI =0.04至0.47）也对饮食行为有显著的直接影响。因此，心理和环境因素介导的社会经济地位和超重或肥胖的非裔美国人的饮食行为之间的关系。增强心理和环境因素的干预措施，如自我效能，健康饮食的障碍，健康观念，以及物理和社会环境，可以改善社会经济弱势的非裔美国人的饮食行为。
The study aim was to examine the relationship between socioeconomic status and dietary behaviors through psychological and environmental mediators among African Americans with overweight or obesity. We conducted a cross-sectional study in 225 African American men and women. Data were analyzed using structural equation modeling with bootstrapping procedures. In the multiple mediation model, socioeconomic status had a significant indirect effect on dietary behaviors through psychological and environmental factors (β=−.27, p=.01, 95% confidence interval [CI]=−0.59 to −0.10), but it had no significant direct effect on dietary behaviors (β=.06, p=.70, 95% CI=−0.21 to 0.39). Socioeconomic status had significant direct effects on psychological (β=.52, p=.01, 95% CI=0.31 to 0.77) and environmental factors (β=−.40, p=.03, 95% CI=−0.53 to −0.25). Psychological (β=−.31, p=.02, 95% CI=−0.68 to −0.04) and environmental factors (β=.26, p=.01, 95% CI=0.04 to 0.47) also showed significant direct effects on dietary behaviors. Thus, psychological and environmental factors mediated the relationship between socioeconomic status and dietary behaviors in African Americans with overweight or obesity. Interventions that enhance psychological and environmental factors such as self-efficacy, perceived barriers to healthy eating, health perceptions, and physical and social environments may improve dietary behaviors among socioeconomically disadvantaged African Americans.
