Information regarding associations between types of away-from-home family meal sources and obesity and other chronic diseases could help guide dietetics practitioners. The present study describes the purchase frequency of away-from-home food sources for family dinner (fast food, other restaurant purchases, home delivery, and takeout foods) and associations with weight status and percent body fat among adolescents (n=723) and parents (n=723) and related biomarkers of chronic disease among adolescents (n=367). A cross-sectional study design was used with baseline parent surveys and anthropometry/fasting blood samples from two community-based obesity studies (2006-2008) in Minnesota. Logistic regression and general linear modeling assessed associations between frequency of family dinner sources (weekly vs none in past week) and outcomes (parent and adolescent overweight/obesity and percent body fat; adolescent metabolic risk cluster z score, cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein, triglycerides, fasting glucose, insulin, and systolic blood pressure. Models accounted for clustering and adjusted for study allocation, baseline meal frequency, and demographic characteristics. The odds of overweight/obesity were considerably greater when families reported at least one away-from-home dinner purchase in the past week (odds ratio=1.2 to 2.6). Mean percent body fat, metabolic risk cluster z scores, and insulin levels were significantly greater with weekly purchases of family dinner from fast-food restaurants (P<0.05). Mean percent body fat, metabolic risk cluster z scores, and high-density lipoprotein levels were significantly higher for families who purchased weekly family dinner from takeout sources (P<0.05). Although frequent family dinners may be beneficial for adolescents, the source of dinners is likely as important in maintaining a healthy weight. Interventions should focus on encouragement of healthful family meals.
关于外出就餐家庭膳食来源类型与肥胖及其他慢性疾病之间关联的信息，有助于指导饮食从业者。本研究描述了家庭晚餐外出就餐食物来源（快餐、其他餐厅购买食物、外卖和外带食品）的购买频率，以及与青少年（n = 723）和父母（n = 723）的体重状况和体脂百分比之间的关联，以及青少年（n = 367）慢性疾病相关生物标志物之间的关联。采用横断面研究设计，对明尼苏达州两项基于社区的肥胖研究（2006 - 2008年）中的家长进行基线调查，并采集人体测量数据/空腹血样。逻辑回归和一般线性模型评估了家庭晚餐来源频率（过去一周每周一次与无）与结果（父母和青少年超重/肥胖以及体脂百分比；青少年代谢风险聚类z评分、胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白、甘油三酯、空腹血糖、胰岛素和收缩压）之间的关联。模型考虑了聚类情况，并对研究分配、基线用餐频率和人口统计学特征进行了调整。当家庭报告在过去一周至少有一次外出就餐购买晚餐时，超重/肥胖的几率显著更高（优势比 = 1.2至2.6）。每周从快餐店购买家庭晚餐时，平均体脂百分比、代谢风险聚类z评分和胰岛素水平显著更高（P < 0.05）。每周从外卖来源购买家庭晚餐的家庭，平均体脂百分比、代谢风险聚类z评分和高密度脂蛋白水平显著更高（P < 0.05）。虽然频繁的家庭晚餐可能对青少年有益，但晚餐的来源在维持健康体重方面可能同样重要。干预措施应侧重于鼓励健康的家庭膳食。
