能量补偿指数通常被用来检验儿童食物摄入量的自我调节。然而，之前的研究没有考虑到儿童在完全自主的情况下的自我调节能力。这项研究使用无限午餐自助餐范式，研究了幼儿食物摄入量的自我调节，以及卡路里控制对食物/营养摄入量的影响。受试者为66名儿童(MAGE=6.14，SD=1.15岁；男性68.2%；拉丁裔89.4%；超重/肥胖59.1%[OV/OB])。孩子们参加了一项交叉研究试验，试验间隔一周。参与者在每次试验中吃了两种不同类型的预装食物，然后吃了一顿临时午餐。计算补偿指数(CompX)以确定食物摄入量的自我调节水平。比较两组间的食物/营养素摄入量。结果表明，OV/OB儿童的自我调节能力较正常体重儿童差(t=2.19，p=0.032；Hedge‘s g=0.55)。OV/OB组与正常体重组在食物摄取/选择方面存在显著差异。与体重正常的儿童相比，OV/OB儿童在高能量预负荷后摄入的卡路里、脂肪和胆固醇更高(d‘s范围：0.31-0.48)。我们的发现支持了正常儿童和OV/OB儿童之间自我调节能力的差异以及他们为补偿而选择的项目。
Energy compensation indices are commonly used to examine self-regulation of food intake in children. However, previous studies failed to consider children’s ability to self-regulate under complete autonomy. This study examined self-regulation of food intake among young children and the effect of calorie manipulation on food/nutrient intake using an unlimited lunch buffet paradigm. Participants were 66 children (Mage = 6.14, SD = 1.15 years; 68.2% male; 89.4% Latinx; 59.1% overweight/obese [OV/OB]). Children participated in a crossover research trial, one week apart. Participants consumed 2 different types of preloads followed by an ad-libitum lunch during each trial. A compensation index (COMPX) was calculated to identify the level of self-regulation in food intake. Food/nutrient intake was compared between both sessions. Results indicated OV/OB children showed poorer self-regulation compared to healthy weight children (t=2.19, p = .032; Hedges’ g = 0.55). There were significant differences in food intake/selection between OV/OB and healthy weight groups. OV/OB children consumed a higher amount of calorie, fat, and cholesterol after the high energy preload compared to healthy weight children (d’s range: 0.31-0.48). Our findings support differences between the amount of self-regulation between normal and OV/OB children as well as the items they select in order to compensate.
