To describe the dietary intake patterns of women before and after breast cancer diagnosis.
3,084 women (age range 27 to 70 years) who had been treated for early-stage breast cancer, who were free of recurrent disease, and who were willing to complete study questionnaires.
A descriptive analysis of baseline demographic and lifestyle questionnaire data, including reported dietary intake data from women who have had breast cancer participating in a randomized, controlled dietary intervention trial. Outcomes include dietary intakes of high- and low-fat foods, fruits and vegetables, and whole grains.
Analyses included frequency of intake of selected food items, chi2 analysis to determine associations between reported intakes and demographic and personal characteristics, and logistic regression to assess odds of making more healthful changes.
Women who have had breast cancer reported higher fruit, vegetable, and fiber-rich food intakes (58%, 60%, 38% more, respectively) and lower intakes of high-fat foods, including fast foods, after diagnosis. Those older than age 60 years were more likely to report no change in intake, including red meat (41%), vegetables (51%), and whole grains (62%). Odds ratios (OR) for more healthful diet choices varied by age and time since diagnosis. The longer the time since diagnosis the more likely women selected low-fat (vs high-fat) foods (OR 1.56, 95% confidence interval [CI] 1.16-2.09 for 3 to 4 years vs <1 year after diagnosis) and reduced added fats (OR 1.47, 95% CI 1.17-1.84 for 3 to 4 years vs <1 year after diagnosis).
Women who have had breast cancer report more healthful diet habits after diagnosis. Through nutrition education and counseling, dietetics professionals may be able to promote healthful and evidence-based eating habits among women previously treated for breast cancer.
描述乳腺癌确诊前后女性的饮食摄入模式。
3084名女性（年龄范围27至70岁），她们曾接受早期乳腺癌治疗，无疾病复发，且愿意完成研究问卷。
对基线人口统计学和生活方式问卷数据进行描述性分析，包括参与一项随机对照饮食干预试验的乳腺癌女性报告的饮食摄入数据。结果包括高脂肪和低脂肪食物、水果和蔬菜以及全谷物的饮食摄入量。
分析包括所选食物项目的摄入频率、用于确定报告摄入量与人口统计学和个人特征之间关联的卡方分析，以及用于评估做出更健康改变几率的逻辑回归分析。
确诊后，患乳腺癌的女性报告称水果、蔬菜和富含纤维食物的摄入量更高（分别多58%、60%、38%），包括快餐在内的高脂肪食物摄入量更低。60岁以上的女性更有可能报告摄入量没有变化，包括红肉（41%）、蔬菜（51%）和全谷物（62%）。做出更健康饮食选择的优势比（OR）因年龄和确诊后的时间而异。确诊后时间越长，女性选择低脂肪（相对于高脂肪）食物的可能性越大（确诊后3至4年与确诊后<1年相比，OR为1.56，95%置信区间[CI]为1.16 - 2.09），减少添加脂肪的可能性越大（确诊后3至4年与确诊后<1年相比，OR为1.47，95%CI为1.17 - 1.84）。
患乳腺癌的女性在确诊后报告有更健康的饮食习惯。通过营养教育和咨询，饮食专业人员或许能够在曾接受乳腺癌治疗的女性中推广健康且基于证据的饮食习惯。
