BACKGROUND/OBJECTIVES: Appetitive traits have a central role in energy intake and development of obesity. Child Eating Behavior Questionnaire (CEBQ) is a validated psychometric tool to measure appetitive traits in children. This study sought to assess the CEBQ factor structure in children with obesity. We hypothesized that hedonic traits are more prominent with obesity and in older children.
SUBJECTS/METHODS: This cross-sectional observational study used CEBQ data from three geographically diverse centers in children with obesity. Eight known CEBQ subscales and the established factor model were compared by severity of obesity, age and sex. Exploratory factor analysis (EFA) to define the appetitive trait factor structure was undertaken in a training dataset and validated in a test set.
Children with obesity (n=814) showed higher food response, enjoyment of food, emotional overeating and desire to drink compared to population-based controls (p < 0.001) that correlated with obesity severity. The EFA identified a novel six-factor model with a new "Food avidity" factor that explained 15.8% of the variance. Satiety responsiveness (p < 0.001) and emotional undereating (p = 0.03) were lower in youth over six years compared to younger, while food fussiness and food avidity were the same, without any sex differences.
CEBQ is useful to assess appetitive traits in children with obesity. The novel factor structure in youth with obesity suggests that temporal or phenotypic differences necessitate a revision of the established factor model. The new factor structure may be used to develop a hyperphagia questionnaire.
背景/目的：食欲特质在能量摄入和肥胖发展中起核心作用。儿童饮食行为问卷（CEBQ）是一种经过验证的心理测量工具，用于测量儿童的食欲特质。本研究旨在评估肥胖儿童的CEBQ因子结构。我们假设享乐性特质在肥胖儿童和年龄较大的儿童中更为突出。
受试者/方法：这项横断面观察性研究使用了来自三个地理位置不同的中心的肥胖儿童的CEBQ数据。通过肥胖严重程度、年龄和性别对八个已知的CEBQ子量表和既定的因子模型进行了比较。在一个训练数据集中进行探索性因子分析（EFA）以定义食欲特质因子结构，并在一个测试集中进行验证。
与基于人群的对照组相比，肥胖儿童（n = 814）表现出更高的食物反应、对食物的喜爱、情绪性暴饮暴食和口渴欲望（p < 0.001），且这些与肥胖严重程度相关。EFA确定了一个新的六因子模型，其中有一个新的“食物贪求”因子，解释了15.8%的方差。与较年幼的儿童相比，6岁以上的青少年的饱腹感反应性（p < 0.001）和情绪性饮食不足（p = 0.03）较低，而食物挑剔和食物贪求则相同，且无任何性别差异。
CEBQ有助于评估肥胖儿童的食欲特质。肥胖青少年的新因子结构表明，时间或表型差异需要对既定的因子模型进行修订。新的因子结构可用于开发一种食欲过盛问卷。
