Little is known about the dietary behaviors of African-American breast cancer survivors (AABCS). We sought to describe dietary intake and quality in AABCS and examine associations with demographic, social, lifestyle, and body composition factors to potentially inform the development of effective dietary interventions.
Baseline data from a prospective weight loss trial of 210 AABCS were assessed. A food frequency questionnaire was used to evaluate dietary intake and diet quality via the Healthy Eating Index 2010 (HEI-2010) and Alternative Healthy Eating Index 2010 (AHEI-2010). Linear regression analysis was conducted to determine the most influential variables on diet quality.
Mean HEI- and AHEI-2010 total scores were 65.11 and 56.83 indicating that diet quality needs improvement. Women were the least adherent to recommendations for intake of whole grains, dairy, sodium, empty calories, sugary beverages, red/processed meats, and trans-fat. Increased self-efficacy for healthy eating behaviors, more years of education (AHEI only), negative smoking status, smaller waist circumference, and increased physical activity (HEI only) were significantly associated with higher diet quality scores.
Our findings suggest the diet quality of AABCS needs improvement. Intervention programs may achieve higher diet quality in AABCS by focusing on increasing self-efficacy for healthy eating behaviors.
对于非裔美国乳腺癌幸存者(AABCS)的饮食行为,我们知之甚少。我们旨在描述 AABCS 的饮食摄入和质量,并研究其与人口统计学、社会、生活方式和身体成分因素的关联,以便为制定有效的饮食干预措施提供信息。
对 210 名 AABCS 的前瞻性减肥试验的基线数据进行评估。使用食物频率问卷评估饮食摄入和通过健康饮食指数 2010(HEI-2010)和替代健康饮食指数 2010(AHEI-2010)评估饮食质量。进行线性回归分析以确定对饮食质量影响最大的变量。
平均 HEI- 和 AHEI-2010 总分分别为 65.11 和 56.83,表明饮食质量需要改善。女性在摄入全谷物、乳制品、钠、空卡路里、含糖饮料、红色/加工肉类和反式脂肪方面最不遵守建议。健康饮食行为自我效能感增加、受教育年限增加(仅 AHEI)、吸烟状况为阴性、腰围较小和身体活动增加(仅 HEI)与更高的饮食质量评分显著相关。
我们的研究结果表明 AABCS 的饮食质量需要改善。干预计划可以通过专注于增加健康饮食行为的自我效能感来提高 AABCS 的饮食质量。
