To investigate children's ability to self-regulate energy intake and to determine whether individual differences in the precision of food intake regulation are related to children's anthropometric measures. We collected information pertaining to parental adiposity and dieting practices, as well as mothers' child-feeding practices. Of special interest was the degree of control imposed by mothers over their children's food intake. Our intent was to explore whether these variables might influence children's regulation of energy intake.
Seventy-seven 3-5-year-old children who attended a university preschool setting and their parents participated in this experiment.
Children completed controlled, two-part meals used to estimate their ability to adjust food intake in response to changes in caloric density of the diet. An eating index, reflecting children's precision in the ability to regulate energy intake, was correlated to children's anthropometric measures. These correlations provided evidence for a relation between children's body fat stores and their responsiveness to caloric density cues: Pearson correlation coefficients revealed that children with greater body fat stores were less able to regulate energy intake accurately. The best predictor of children's ability to regulate energy intake was parental control in the feeding situation: mothers who were more controlling of their children's food intake had children who showed less ability to self-regulate energy intake (r = -.67, P < .0001).
These findings suggest that the optimal environment for children's development of self-control of energy intake is that in which parents provide healthy food choices but allow children to assume control of how much they consume.
研究儿童自我调节能量摄入的能力,并确定食物摄入量调节精度的个体差异是否与儿童的人体测量指标相关。我们收集了有关父母肥胖和节食习惯以及母亲喂养方式的信息。特别感兴趣的是母亲对孩子食物摄入量的控制程度。我们的目的是探讨这些变量是否可能影响儿童的能量摄入调节。
77名就读于大学幼儿园的3至5岁儿童及其父母参与了本实验。
儿童完成了受控制的两部分进餐,用于评估他们根据饮食热量密度变化调整食物摄入量的能力。反映儿童调节能量摄入能力精度的进食指数与儿童的人体测量指标相关。这些相关性为儿童体内脂肪储存与其对热量密度线索的反应之间的关系提供了证据:皮尔逊相关系数显示,体内脂肪储存较多的儿童准确调节能量摄入的能力较弱。儿童调节能量摄入能力的最佳预测指标是喂养情况下父母的控制:对孩子食物摄入量控制更强的母亲,其孩子自我调节能量摄入的能力较弱(r = -0.67,P < 0.0001)。
这些发现表明,儿童发展能量摄入自我控制能力的最佳环境是父母提供健康的食物选择,但允许孩子自行控制摄入量。
