We assessed the individual constructs that comprise "picky eaters" and determined the relationship of each construct to parental perception of their child's weight status, parental pressure-to-eat, and the child's body mass index z-score (BMIz). We developed a questionnaire including 7 commonly used measures of picky eating, which was completed by parents of 2-8 year-olds in pediatric clinics. We performed exploratory factor analysis, confirmatory factor analysis, and model fit. Regression models assessed the association of each picky eating factor to weight perception, pressure-to-eat, and BMIz. We identified three distinct picky eating factors: trying new foods, eating sufficient quantity, and desire for specific food preparation. Each factor had Cronbach's alpha > 0.7 and acceptable model fit. No factors were associated with weight perception. Parents who were more concerned their child did not eat enough were more likely to pressure-to-eat, and these children had lower BMIz. These components of picky eating should be addressed by primary care providers.
我们评估了构成“挑食者”的各个结构，并确定了每个结构与父母对孩子体重状况的感知、父母的进食压力以及孩子的体重指数 z 分数（BMIz）之间的关系。我们开发了一个包括 7 种常用挑食测量方法的问卷，由儿科诊所的 2-8 岁儿童的父母填写。我们进行了探索性因素分析、验证性因素分析和模型拟合。回归模型评估了每个挑食因素与体重感知、进食压力和 BMIz 的关联。我们确定了三个不同的挑食因素：尝试新食物、摄入足够的量和对特定食物准备的渴望。每个因素的克朗巴赫α系数均大于 0.7，模型拟合良好。没有因素与体重感知相关。那些更担心孩子吃得不够的父母更有可能施加进食压力，而这些孩子的 BMIz 较低。这些挑食因素应该由初级保健提供者来处理。
