OBJECTIVES
To examine lifestyle behaviors among non-Hispanic black and white women with a family history of breast cancer and determine the extent to which they meet American Cancer Society (ACS) Nutrition and Physical Activity Recommendations for Breast Cancer Prevention.
METHOD
Cross-sectional data from 44,364 women enrolled in the Sister Study (2009), a study of sisters of women with breast cancer within the U.S., were analyzed. Descriptive statistics and chi-square analyses were used to examine body mass index and lifestyle behaviors (e.g., exercise, diet, and smoking) and to determine percentages of women meeting ACS recommendations.
RESULTS
Black women consumed a lower percentage of calories from fat (mean 36.90% vs. 37.17%) and were more likely to meet ACS alcohol recommendations than whites. White women consumed more fruits and vegetables/day (mean 4.81 vs. 4.41) than black women and were more likely to meet ACS guidelines for physical activity (26.4% vs. 18.2%) and body mass index (42.5% vs. 16.7%).
CONCLUSION
Despite an elevated risk for breast cancer due to a family history of breast cancer, the majority of women were no more likely than women in the general population to engage in healthy lifestyle behaviors. These women may benefit from lifestyle behavior risk-reduction counseling.
目的
研究有乳腺癌家族史的非裔美国女性和白种女性的生活方式行为，并确定她们符合美国癌症协会（ACS）预防乳腺癌的营养和身体活动建议的程度。
方法
对美国“姐妹研究”（2009 年）中 44364 名女性的横断面数据进行分析。采用描述性统计和卡方分析来检查体重指数和生活方式行为（如运动、饮食和吸烟），并确定符合 ACS 建议的女性比例。
结果
黑种女性摄入的脂肪热量百分比（均值 36.90%比 37.17%）较低，且比白种女性更符合 ACS 酒精建议。白种女性每天摄入的水果和蔬菜（均值 4.81 比 4.41）多于黑种女性，且更符合 ACS 身体活动（26.4%比 18.2%）和体重指数（42.5%比 16.7%）指南。
结论
尽管由于家族乳腺癌病史，这些女性患乳腺癌的风险增加，但与一般人群中的女性相比，大多数女性不太可能采取健康的生活方式行为。这些女性可能受益于生活方式行为降低风险的咨询。
