Alcohol intake is a known risk factor for breast cancer. National organizations recommend that women consume no more than one serving of alcohol per day, if at all; however, many women exceed this recommendation, and some are unwilling to decrease consumption. Our study sought to identify factors associated with women's unwillingness to decrease their alcohol intake to decrease their breast cancer risk.
942 women in a screening mammography cohort were asked questions about their demographics, personal and family health history, lifestyle factors, and willingness/unwillingness to decrease alcohol intake to decrease their breast cancer risk. Univariate and multivariate analyzes of their responses were performed.
13.2% of women in our cohort indicated they were unwilling to decrease their alcohol intake to reduce their breast cancer risk. After adjusting for potential confounders, women who were 60 years and older were more than twice as unwilling to decrease their alcohol intake compared to their younger counterparts ( = .0002). Women who had an annual household income of more than $200,000 were 1.75 times more unwilling to decrease their alcohol intake compared to their less affluent counterparts ( = .033). Unwillingness was not significantly associated with race/ethnicity, education, having a first-degree family member with cancer, health perception, breast cancer risk perception, or BMI.
Levels of unwillingness to decrease alcohol intake differed by age and household income. An opportunity is present to potentially decrease breast cancer risk in the community by educating women, especially older and more affluent women, about alcohol as a risk factor for breast cancer and the importance of limiting one's alcohol intake.
饮酒是乳腺癌的已知危险因素。国家组织建议女性每天最多饮用一份酒精饮料，如果有的话；然而，许多女性超过了这一建议，并且有些女性不愿意减少饮酒量。我们的研究旨在确定与女性不愿意减少饮酒量以降低乳腺癌风险相关的因素。
在一项筛查乳房 X 光摄影队列中，942 名女性被问及她们的人口统计学、个人和家族健康史、生活方式因素，以及是否愿意/不愿意减少饮酒量以降低乳腺癌风险。对她们的回答进行了单变量和多变量分析。
我们队列中的 13.2%的女性表示不愿意减少饮酒量以降低乳腺癌风险。在调整了潜在的混杂因素后，60 岁及以上的女性与年轻女性相比，不愿意减少饮酒量的可能性是其两倍多（= 0.0002）。年收入超过 20 万美元的女性与收入较低的女性相比，不愿意减少饮酒量的可能性高出 1.75 倍（= 0.033）。不愿意减少饮酒量与种族/族裔、教育程度、有一级亲属患有癌症、健康认知、乳腺癌风险认知或 BMI 无关。
不愿意减少饮酒量的程度因年龄和家庭收入而异。通过教育女性，特别是年龄较大和较富裕的女性，了解酒精作为乳腺癌的一个危险因素以及限制饮酒量的重要性，有可能在社区中降低乳腺癌风险。
