Parents influence child weight through interactions that shape the development of child eating behaviors. In this study we examined the association between maternal autonomy promoting serving practices and child appetite regulation. We predicted that maternal autonomy promoting serving practices would be positively associated with child appetite regulation. Participants were low-income Latino children-a group at high risk for the development of childhood obesity. A total of 186 low-income Latina mothers and their 4-5 year old children came to a laboratory on two separate days. On the first day, mothers and children chose foods for a meal from a buffet and were audio/videotaped so that maternal autonomy promoting serving practices could be later coded. On the second day, children completed the Eating in the Absence of Hunger (EAH) task to measure child appetite regulation. Mothers also completed the Child Eating Behavior Questionnaire (CEBQ) to measure other aspects of child appetite regulation (food responsiveness, satiety responsiveness, and emotional overeating). Maternal autonomy promotion during serving was assessed using seven separate measures of child and maternal behavior. Principal components analyses of these serving measures yielded three components: allows child choice, child serves food, and mother does not restrict. Consistent with hypotheses, maternal autonomy promoting serving practices (i.e., allows child choice and does not restrict) were negatively associated with maternal reports of child food responsiveness and emotional overeating (CEBQ). The results for the EAH task were more complex-mothers who were autonomy promoting in their serving practices had children who ate the most in the absence of hunger, but this linear effect was moderated somewhat by a quadratic effect, with moderate levels of autonomy promotion during serving associated with the greatest child EAH.
父母通过塑造儿童饮食行为发展的互动来影响孩子的体重。在本研究中,我们考察了母亲促进自主进食行为与儿童食欲调节之间的关联。我们预测,母亲促进自主进食行为将与儿童食欲调节呈正相关。研究对象为低收入拉丁裔儿童——这是一个儿童肥胖风险较高的群体。共有186名低收入拉丁裔母亲及其4至5岁的孩子在两个不同的日子来到实验室。第一天,母亲和孩子从自助餐中选择一顿饭的食物,并进行音频/视频记录,以便之后对母亲促进自主进食行为进行编码。第二天,孩子们完成“不饿时进食”(EAH)任务以测量儿童食欲调节。母亲们还完成了儿童饮食行为问卷(CEBQ)以测量儿童食欲调节的其他方面(食物反应性、饱腹感反应性和情绪性暴饮暴食)。使用七种单独的儿童和母亲行为测量方法来评估母亲在喂食过程中的自主促进情况。对这些喂食测量方法进行主成分分析得出三个成分:允许孩子选择、孩子自己取食物以及母亲不限制。与假设一致,母亲促进自主进食行为(即允许孩子选择且不限制)与母亲报告的孩子食物反应性和情绪性暴饮暴食(CEBQ)呈负相关。EAH任务的结果更为复杂——在喂食过程中促进自主的母亲,其孩子在不饿时吃得最多,但这种线性效应在一定程度上受到二次效应的调节,喂食过程中适度促进自主与孩子最大的EAH相关。
