This pilot study aimed to determine the effects of an intervention on nutrition knowledge, food parents serve, and children's dietary intake.
A single-group pre-/posttest design was used with 45 mothers and their 4- to 6-year-old children. After pretesting, parents received child nutrition information and portion-related activities.
Paired samples t-tests revealed that from pre- to posttest the average calories mothers served and the average calories children ate significantly decreased (medium effect size). Medium effects also were recognized from pre- to posttest for the carbohydrates served and carbohydrates consumed. No significant change was found in parents' nutrition knowledge.
Interventions focusing on skill building rather than on increasing knowledge may more effectively lead to changed child intake.
本试点研究旨在确定一项干预措施对营养知识、家长提供的食物以及儿童饮食摄入量的影响。
采用单组前后测设计，研究对象为45位母亲及其4至6岁的孩子。在进行前测之后，家长们接受了儿童营养信息及与食物分量相关的活动。
配对样本t检验显示，从前测到后测，母亲提供的平均卡路里量以及孩子摄入的平均卡路里量均显著下降（效应量中等）。从前测到后测，提供的碳水化合物量和摄入的碳水化合物量也呈现中等效应。家长的营养知识未发现显著变化。
侧重于技能培养而非知识增加的干预措施可能会更有效地改变儿童的摄入量。
