Prior research suggests that frequent family meals are associated with lower body mass index (BMI) among children and adolescents. The primary focus of this study was examining associations of reported frequency of family meals with reported BMI for multiple members of family units that included adults and adolescents. A secondary focus was examining settings for family meals and body weight (home and away from home). A cross-sectional survey recruited 327 individuals in 103 family units visiting one U.S. University. Results revealed that for individuals, frequency of family meals at home was inversely related with BMI, while frequency of family meals away from home was directly related with BMI. Family role analyses showed that frequency of family meals eaten by fathers and sons at home was inversely related to BMI, while for only fathers the frequency of family meals away from home was directly related to BMI. Full family unit analyses summed family member characteristics and found associations between family meal frequency and family BMI at home were inverse, but they were direct away from home. Multilevel regression models indicated that family level characteristics accounted for a substantial portion of the variability in body weight measures both at home and away from home. These findings reveal that meal settings, family roles, and full family units help to understand family meals and body weight.
先前的研究表明，频繁的家庭用餐与儿童和青少年的体重指数（BMI）较低有关。本研究的主要重点是检查家庭用餐频率与包括成年人和青少年在内的家庭单位中多个成员的报告 BMI 之间的关联。次要重点是检查家庭用餐和体重的环境（家庭内和家庭外）。一项横断面调查在美国一所大学招募了 103 个家庭单位的 327 名个人。结果表明，对于个体而言，家庭用餐的频率与 BMI 呈负相关，而家庭外用餐的频率与 BMI 呈正相关。家庭角色分析表明，父亲和儿子在家中用餐的家庭用餐频率与 BMI 呈负相关，而仅父亲在外用餐的频率与 BMI 呈正相关。全家庭单位分析汇总了家庭成员的特征，并发现家庭用餐频率与家庭内 BMI 的关联呈负相关，但与家庭外 BMI 的关联呈正相关。多层次回归模型表明，家庭层面的特征在家内和家庭外的体重指标的变异性方面占很大比例。这些发现表明，膳食设置、家庭角色和完整的家庭单位有助于理解家庭膳食和体重。
