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.
