To confirm previously reported associations between family meal frequency and dietary intake, and to examine family cohesion as a potential mediator of this relationship.
Cross-sectional observational study. Data collected at baseline via questionnaire.
Randomized, controlled household weight gain prevention trial.
Participants were 152 adults and 75 adolescents from 90 community households.
Family meal frequency assessed with a single question. Perceived family cohesion measured by the Family Adaptability and Cohesion Evaluation Scale-III. Usual intake of targeted food items assessed with modified food frequency questionnaire.
Hierarchical linear regression with mediation analysis. Statistical significance set at α-level .05.
Family meal frequency was associated with intake of fruits and vegetables in adults, and sweets and sugar-sweetened beverages in adolescents. Family meal frequency was positively correlated with perceived family cohesion (r = 0.41, P < .01). Partial mediation by family cohesion was observed for family meal frequency and sweets intake in adolescents.
Results suggest that family cohesion is not a consistent mediator of relationship between family meal frequency and individual dietary intake. Future studies should assess additional plausible mediators of this relationship in order to better understand the effect of family meals on dietary intake.
确认之前关于家庭用餐频率与饮食摄入之间关联的报告，并研究家庭内聚力是否是这种关系的潜在中介因素。
横断面观察性研究。数据通过问卷调查于基线收集。
随机、对照家庭体重增加预防试验。
90 户社区家庭的 152 名成年人和 75 名青少年。
家庭用餐频率通过一个问题进行评估。采用家庭适应性和内聚力评估量表第三版评估感知家庭内聚力。通过改良食物频率问卷评估目标食物的常规摄入量。
分层线性回归与中介分析。统计显著性水平设定为.05。
家庭用餐频率与成年人的水果和蔬菜摄入量以及青少年的甜食和含糖饮料摄入量有关。家庭用餐频率与感知家庭内聚力呈正相关（r = 0.41，P <.01）。家庭内聚力对内聚力与青少年甜食摄入量之间的关系起部分中介作用。
结果表明，家庭内聚力并不是家庭用餐频率与个体饮食摄入之间关系的一致中介因素。未来的研究应该评估这种关系的其他潜在中介因素，以便更好地了解家庭用餐对饮食摄入的影响。
