A healthy diet is associated with lower risk of chronic disease. African Americans generally have poor diet quality and experience a higher burden of many chronic diseases. We examined the associations of demographic and psychosocial factors and barriers to diet quality among African American adults. This cross-sectional study included 100 African American adults in a southeastern metropolitan area. Psychosocial factors (social support, self-efficacy), and barriers to healthy eating were assessed with validated measures. Diet quality was assessed using the Healthy Eating Index (HEI-2010). Nested linear regressions were used to examine the association between the variables of interest and HEI scores. Participants reported having social support (M (mean) = 2.0, SD (standard deviation) = 0.6, range 0⁻3), high levels of self-efficacy (M = 3.1, SD = 0.7, range 1⁻4), and low barriers (M = 1.4, SD = 0.6, range 0⁻4) to engage in healthy eating but total mean HEI scores needed improvement (M = 54.8, SD = 10.9, range 27.1⁻70.0). Participants consumed significantly higher empty calories and lower whole fruits, dairy, and total protein foods than the national average. Barriers to healthy eating (b = -12.13, = 0.01) and the interaction between age and barriers (b = 0.25, = 0.02) were most strongly associated with lower HEI scores. Younger African Americans with the highest barriers to healthy eating had the lowest HEI scores. Culturally appropriate interventions targeting empty calories, barriers to healthy eating, and knowledge of the Dietary Guidelines for Americans are needed for African Americans.
健康的饮食与慢性病风险降低有关。非裔美国人的饮食质量普遍较差,多种慢性病的负担也更重。我们研究了非裔美国成年人的人口统计学和社会心理因素以及饮食质量障碍之间的关联。这项横断面研究包括东南部大都市区的 100 名非裔美国成年人。使用经过验证的措施评估了社会心理因素(社会支持、自我效能感)和健康饮食障碍。使用健康饮食指数(HEI-2010)评估饮食质量。嵌套线性回归用于检验感兴趣变量与 HEI 评分之间的关系。参与者报告他们有社会支持(M(平均值)= 2.0,SD(标准差)= 0.6,范围 0⁻3)、高水平的自我效能感(M = 3.1,SD = 0.7,范围 1⁻4)和低饮食障碍(M = 1.4,SD = 0.6,范围 0⁻4),但总平均 HEI 评分需要提高(M = 54.8,SD = 10.9,范围 27.1⁻70.0)。与全国平均水平相比,参与者消耗的空卡路里明显更高,全水果、乳制品和总蛋白质食物的摄入量更低。健康饮食障碍(b = -12.13, = 0.01)和年龄与障碍之间的相互作用(b = 0.25, = 0.02)与较低的 HEI 评分最密切相关。饮食障碍最大的年轻非裔美国人的 HEI 评分最低。需要针对空卡路里、健康饮食障碍和对美国人饮食指南的了解,为非裔美国人提供文化上适当的干预措施。
