Although parental feeding plays an important role in child eating and weight status, high food motivation among children may also be a factor shaping how feeding impacts child weight. This study explored whether individual differences in preschool children's food motivation interacted with mothers' feeding styles in predicting subsequent child weight status. Participants included 129 Hispanic Head Start mother/child dyads. Data were collected at ages 4-5 years (Time 1) and 7-9 (Time 3). Staff measured heights/weights and observed children in an eating in the absence of hunger task. Mothers reported on feeding styles/practices and children's eating behaviors. A principal components analysis derived a measure of highly motivated eating in children. Multiple regressions predicted Time 3 child BMI -scores. Time 3 BMI -scores were positively predicted by authoritative and indulgent feeding styles and negatively predicted by monitoring. Since feeding style interacted with highly motivated eating, separate regressions were run for high and low food motivation in children. Unexpectedly, results showed that authoritative feeding positively predicted Time 3 child BMI -scores only for children showing of food motivation. Characterizing differential parental feeding and child eating phenotypes may assist in tailoring childhood obesity prevention programs for the target populations.
尽管父母的喂养方式在孩子的饮食和体重状况中起着重要作用，但孩子自身较高的食物动机也可能是影响喂养对孩子体重作用方式的一个因素。本研究探讨了学龄前儿童食物动机的个体差异与母亲的喂养方式在预测孩子后续体重状况时是否存在相互作用。研究对象包括129对西班牙裔开端计划母子。在孩子4至5岁（时间1）和7至9岁（时间3）时收集数据。工作人员测量身高/体重，并观察孩子在不饥饿状态下的进食情况。母亲们报告了喂养方式/行为以及孩子的饮食行为。主成分分析得出了一项衡量孩子高食物动机进食的指标。多元回归分析预测了时间3时孩子的体重指数得分。时间3时的体重指数得分受到权威型和纵容型喂养方式的正向预测，受到监督型喂养方式的负向预测。由于喂养方式与高食物动机进食存在相互作用，因此针对孩子食物动机高和低的情况分别进行了回归分析。出乎意料的是，结果显示，权威型喂养仅对食物动机高的孩子的时间3时的体重指数得分有正向预测作用。明确不同的父母喂养方式和孩子饮食表型可能有助于为目标人群量身定制儿童肥胖预防项目。
