Understanding the degree to which parents may influence healthy behaviors may provide opportunities to intervene among populations at increased risk of diseases, such as breast cancer. In this study, we examined the association between daughters' healthy eating habits and family lifestyle behaviors among girls and their families by using baseline data from the LEGACY (Lessons in Epidemiology and Genetics of Adult Cancer from Youth) Girls Study. Our objective was to examine the relationship between daughters' healthy eating and family lifestyle behaviors and to compare these associations between families with and without a history of breast cancer.
We examined demographic and lifestyle data from a cohort of 1,040 girls aged 6 to 13 years from year 1 (2011) of the LEGACY study. Half had a family history of breast cancer (BCFH). We used mixed-effects linear regression to assess the influence of the mother and father's physical activity, family relationship scores, the mother's diet, the family's income, and the daughter's sports participation, age, body mass index (BMI), and race/ethnicity on the daughter's Healthy Eating Index (HEI) score.
Daughters' healthy eating was significantly correlated with the mother's diet (r[668] = 0.25, P = .003) and physical activity (r[970] = 0.12, P = .002), the father's physical activity (r[970] = 0.08, P = .01), and the family income (r[854] = 0.13, P = .006). Additionally, the mother's diet (β coefficient = 0.71, 95% CI, 0.46-0.88, P = .005) and family income (β coefficient = 3.28, 95% CI, 0.79-5.78, P = .002) significantly predicted a daughter's healthy eating. Analyses separated by family history status revealed differences in these associations. In families without a history of breast cancer, only the mother's diet (β coefficient = 0.62; 95% CI, 0.29-0.95; P = .001) significantly predicted the daughter's healthy eating. In families with a history of breast cancer, the mother's diet (β coefficient = 0.73, 95% CI, 0.42-1.03, P = .006) and family income (β coefficient = 6.24; 95% CI, 2.68-9.80; P = .004) significantly predicted a daughter's healthy eating.
A mother's diet and family income are related to the daughter's healthy eating habits, although differences exist among families by family history of breast cancer.
了解父母对健康行为的影响程度，可能为干预具有疾病风险的人群（如乳腺癌）提供机会。在这项研究中，我们通过使用 LEAGUE（青少年时期成人癌症的流行病学和遗传学研究）女孩研究的基线数据，检查了女孩及其家庭中女儿健康饮食习惯与家庭生活方式行为之间的关系。我们的目的是检验女儿健康饮食与家庭生活方式行为之间的关系，并比较有和无乳腺癌家族史家庭之间的这些关联。
我们分析了来自 LEAGUE 研究第 1 年（2011 年）的 1040 名年龄在 6 至 13 岁的女孩的队列中的人口统计学和生活方式数据。其中一半有乳腺癌家族史（BCFH）。我们使用混合效应线性回归来评估母亲和父亲的体力活动、家庭关系评分、母亲的饮食、家庭收入以及女儿的运动参与、年龄、体重指数（BMI）和种族/族裔对女儿健康饮食指数（HEI）评分的影响。
女儿的健康饮食与母亲的饮食（r[668] = 0.25，P =.003）和体力活动（r[970] = 0.12，P =.002）、父亲的体力活动（r[970] = 0.08，P =.01）和家庭收入（r[854] = 0.13，P =.006）显著相关。此外，母亲的饮食（β系数= 0.71，95%CI，0.46-0.88，P =.005）和家庭收入（β系数= 3.28，95%CI，0.79-5.78，P =.002）显著预测女儿的健康饮食。按家族史状况进行的分析显示出这些关联存在差异。在没有乳腺癌家族史的家庭中，只有母亲的饮食（β系数= 0.62；95%CI，0.29-0.95；P =.001）显著预测女儿的健康饮食。在有乳腺癌家族史的家庭中，母亲的饮食（β系数= 0.73，95%CI，0.42-1.03，P =.006）和家庭收入（β系数= 6.24；95%CI，2.68-9.80；P =.004）显著预测女儿的健康饮食。
母亲的饮食和家庭收入与女儿的健康饮食习惯有关，但乳腺癌家族史不同的家庭之间存在差异。
