背景：学龄前儿童始终通过调整食物摄入量来自我调节能量摄入，以反映饮食的能量密度。然而，只有选定的成年人表现出与能量密度线索相关的自我调节技能。目的：目的是检查非西班牙裔白人和西班牙裔儿童能量摄入自我调节的发育特征，并确定食物摄入调节精确度的个体差异是否与儿童的人体测量相关。设计：从 2 所学校招募了 342 名 5-12 岁儿童，其中一所学校主要招收非西班牙裔白人儿童(n = 148) 和西班牙裔社区的另一所学校 (n = 194)。孩子们吃两部分餐，包括预餐和主餐。预载是能量密度高（625 kJ）或低（12.5 M）的水果味饮料。测量儿童用餐时的食物摄入量并估计能量摄入量。饮食补偿指数 (COMPX) 分数反映了儿童调节能量摄入的能力，用于预测儿童的肥胖情况。结果：非西班牙裔白人和西班牙裔儿童都表现出不完全补偿的证据，平均 (SEM) COMPX 分数为 48.6 +/- 6.4%。没有观察到儿童的总体 COMPX 分数存在显着的种族或性别差异；然而，儿童的 COMPX 评分随着年龄的增长而下降（P < 0.05）。母亲体重指数是儿童体重状况的最佳预测指标。结论：5-12 岁儿童对能量密度线索的反应存在个体差异；反应能力随着年龄的增长而下降。
Background: Preschool-aged children consistently self-regulate energy intake by adjusting food intake to reflect the energy density of the diet. However, only select adults demonstrate self-regulation skills related to energy density cues.Objective: The objective was to examine the developmental characteristics of non-Hispanic white and Hispanic children's selfregulation of energy intake and to determine whether individual differences in the precision of food intake regulation were related to the children's anthropornetric measures.Design: Three hundred forty-two 5-12-y-old children were recruited from 2 schools, one school that enrolled predominantly non-Hispanic white children (n = 148) and another school in a Hispanic neighborhood (n = 194). The children ate 2-part meals, which consisted of a preload and a main meal. The preloads were fruit-flavored drinks that were either high (625 kJ) or low (12.5 M) in energy density. The children's food intake at the meal was measured and energy intake was estimated. An eating Compensation Index (COMPX) score, which reflected the children's ability to regulate energy intake, was used to predict the children's adiposity.Results: Both non-Hispanic White and Hispanic children showed evidence of incomplete compensation, with a mean (SEM) COMPX score of 48.6 +/- 6.4%. No significant ethnicity or sex differences in the children's overall COMPX scores were observed; however, the children's COMPX scores decreased with age (P < 0.05). Maternal body mass index was the best predictor of the children's weight status.Conclusion: Children aged 5-12 y show individual variation in their responsiveness to energy density cues; the responsiveness declines with increasing age.
