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,以改善癌症生存率。尽管非洲裔美国人乳腺癌幸存者(AABCS)在任何种族或族裔群体中存活率最低,关于他们坚持癌症特定生活方式建议的信息有限.该研究的目的是测量AABCS对ACS/AICR饮食建议的依从性。
二百十AABCS参加了“前进”干预试验,一个随机的,以社区为基础,6个月的减肥研究,进行了社会人口统计学评估,饮食摄入量(通过食物频率问卷),以及基线时的相关健康因素。我们实施了ACS/AICR提出的饮食建议,并创建了成分和总依从性指数得分。使用描述性统计数据来计算符合建议的妇女比例。使用学生t检验和χ2检验通过中位依从性得分比较参与者特征。
平均总ACS/AICR评分为12.7±2.5,共21分(中位数,13;范围,5至21)。超过90%的人适度或完全坚持限制酒精和红肉和加工肉类的消费,但是大多数人没有达到其他建议吃全谷物,豆类,水果,蔬菜,避免添加糖。总分低于中位数的女性更年轻,BMI较高,受教育年限较少,和较低的收入水平。
本研究扩展了AABCS对癌症幸存者特定饮食指南的依从性的文献。研究结果将为该人群未来的饮食生活方式干预提供信息。
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.
