Parental eating behavior traits have been shown to be related to the adiposity of their young children. It is unknown whether this relationship persists in older offspring or whether rigid or flexible control are involved. The objective of this study was to test the hypothesis that parental eating behavior traits, as measured by the Three-Factor Eating Questionnaire (TFEQ), are related to offspring body weight.
Cross-sectional anthropometric and TFEQ data from phase 2 and 3 of the Québec Family Study generated 192 parent-offspring dyads (offspring age range: 10-37 years). Relationships were adjusted for offspring age, sex and reported physical activity, number of offspring per family and parent body mass index (BMI).
In all parent-offspring dyads, parental rigid control and disinhibition scores were positively related to offspring BMI (r=0.17, P=0.02; r=0.18, P<0.01, respectively). There were no significant relationships between cognitive restraint (P=0.75) or flexible control (P=0.06) with offspring BMI. Regression models revealed that parent disinhibition mediated the relationship between parent and offspring BMI, whereas rigid control of the parent moderated this relationship. The interaction effect between parental rigid control and disinhibition was a significant predictor of offspring BMI (β=0.13, P=0.05).
Family environmental factors, such as parental eating behavior traits, are related to BMI of older offspring, and should be a focus in the prevention of obesity transmission within families.
父母的饮食行为特征与他们年幼子女的肥胖程度有关。目前尚不清楚这种关系是否在年龄较大的子女中持续存在，以及是否涉及刚性或柔性控制。本研究的目的是检验以下假设，即通过三因素饮食问卷（TFEQ）测量的父母饮食行为特征与子女的体重有关。
来自魁北克家庭研究的第 2 阶段和第 3 阶段的横断面人体测量和 TFEQ 数据生成了 192 对父母-子女对（子女年龄范围：10-37 岁）。对子女的年龄、性别和报告的体力活动、每个家庭的子女数量以及父母的体重指数（BMI）进行了调整。
在所有父母-子女对中，父母的刚性控制和去抑制评分与子女的 BMI 呈正相关（r=0.17，P=0.02；r=0.18，P<0.01）。认知约束（P=0.75）或灵活控制（P=0.06）与子女的 BMI 之间无显著关系。回归模型显示，父母的去抑制作用中介了父母和子女 BMI 之间的关系，而父母的刚性控制调节了这种关系。父母刚性控制和去抑制之间的相互作用是子女 BMI 的一个显著预测因子（β=0.13，P=0.05）。
家庭环境因素，如父母的饮食行为特征，与年龄较大的子女的 BMI 有关，应该成为家庭内肥胖传播预防的重点。
