The American Cancer Society (ACS) and the American Institute for Cancer Research (AICR) each created dietary and physical activity guidelines to improve cancer survivorship. Despite African American breast cancer survivors (AABCS) having the lowest survival rates of any racial or ethnic group, limited information exists on their adherence to cancer-specific lifestyle recommendations. The study's purpose was to measure adherence to ACS/AICR dietary recommendations in AABCS.
Two hundred ten AABCS enrolled in the Moving Forward intervention trial, a randomized, community-based, 6-month weight loss study, were assessed for socio-demographics, dietary intake (via food frequency questionnaire), and related health factors at baseline. We operationalized the dietary recommendations put forth by ACS/AICR and created component and total adherence index scores. Descriptive statistics were used to calculate the proportion of women who met recommendations. Student's t test and χ2 tests were used to compare participant characteristics by median adherence scores.
The mean total ACS/AICR score was 12.7 ± 2.5 out of 21 points (median, 13; range, 5 to 21). Over 90% were moderately or completely adherent to limiting alcohol and red & processed meat consumption, but the majority failed to meet the other recommendations to eat whole grains, legumes, fruits, vegetables, and avoid added sugars. Women with total scores below the median were younger, with higher BMI, had fewer years of education, and lower income levels.
The present study extends the literature on AABCS adherence to cancer survivor-specific dietary guidelines. Findings will inform future dietary lifestyle interventions in this population.
美国癌症协会(ACS)和美国癌症研究所(AICR)各自制定了饮食和身体活动指南,以改善癌症患者的生存状况。尽管非裔美国乳腺癌幸存者(AABCS)的生存率是所有种族或族裔中最低的,但关于他们对特定于癌症的生活方式建议的遵守情况的信息有限。本研究的目的是衡量 AABCS 对 ACS/AICR 饮食建议的遵守情况。
210 名参加“向前迈进”干预试验的 AABCS 被纳入这项随机、基于社区的、为期 6 个月的减肥研究,在基线时评估了社会人口统计学、饮食摄入(通过食物频率问卷)和相关健康因素。我们将 ACS/AICR 提出的饮食建议进行了操作化,并创建了成分和总依从指数得分。使用描述性统计来计算符合建议的女性比例。使用学生 t 检验和 χ2 检验比较中位数依从得分的参与者特征。
ACS/AICR 总得分的平均值为 21 分中的 12.7±2.5 分(中位数为 13 分;范围为 5 到 21 分)。超过 90%的人适度或完全遵守限制饮酒和摄入红色和加工肉类的建议,但大多数人未能满足其他建议,即食用全谷物、豆类、水果、蔬菜和避免添加糖。总分低于中位数的女性更年轻,BMI 更高,受教育年限更少,收入水平更低。
本研究扩展了关于 AABCS 对癌症幸存者特定饮食指南的遵守情况的文献。研究结果将为这一人群的未来饮食生活方式干预提供信息。
