Several common theoretical frameworks have posited causal pathways between picky eating, pressuring feeding, and growth in early childhood. The evidence to support these pathways is limited. This observational cohort study sought to examine the cross-lagged associations between mother-reported pressuring feeding, mother-reported child picky eating, and measured weight-for-length z-score (WLZ) across child ages 21, 27, and 33 months (n = 244). Cross-lagged analysis was used to evaluate longitudinal associations between these three constructs. The sample was 50.5% white, 52.3% male and 37.8% of mothers had a high school education or less. Mean WLZ was 0.52, 0.41, and 0.38 at each age, respectively. Pressuring feeding, picky eating, and WLZ each tracked strongly from 21 to 33 months. There were concurrent associations between pressuring feeding and picky eating. However, there were no prospective associations between pressuring feeding and future WLZ; WLZ and future pressuring feeding; pressuring feeding and future picky eating; picky eating and future pressuring feeding; or picky eating and future WLZ. Our results do not support causal relationships between picky eating, pressuring feeding, and growth in toddlerhood. Future work that examines alternative mechanisms shaping growth in early childhood is needed.
几种常见的理论框架假设了幼儿期挑食、强制喂食和生长之间的因果关系。支持这些途径的证据有限。这项观察性队列研究旨在检查母亲报告的强制喂食、母亲报告的儿童挑食和在 21、27 和 33 个月时测量的体重-长度 z 分数（WLZ）之间的交叉滞后关联（n=244）。交叉滞后分析用于评估这三个结构之间的纵向关联。该样本中 50.5%为白人，52.3%为男性，37.8%的母亲接受过高中或以下教育。平均 WLZ 分别为每个年龄的 0.52、0.41 和 0.38。从 21 个月到 33 个月，强制喂食、挑食和 WLZ 都有很强的跟踪性。强制喂食和挑食之间存在同期关联。然而，强制喂食与未来 WLZ 之间没有前瞻性关联；WLZ 与未来的强制喂食；强制喂食与未来的挑食；挑食与未来的强制喂食；或挑食与未来的 WLZ。我们的结果不支持幼儿期挑食、强制喂食和生长之间的因果关系。需要开展未来研究来检验塑造儿童早期生长的替代机制。
