This study aims to examine the effects of an intervention model, Change Nutrition by Doing, in which children act as agents of change – by ‘doing’ – in taking responsibility for the contents of the lunch box they bring from home to consume at an early childhood centre. This quasi-randomised case-control trial consisted of 35 Israeli kindergartens whose teachers were participating in an in-service training programme of an intervention model for improving children’s healthy nutritional behaviour. The control group consisted of 26 kindergartens whose teachers were participating in other in-service training programmes. The intervention model ran for eight months. The quality of the contents of the children’s lunch box in the experimental groups was measured pre- and post-intervention through structured observations that yielded standardised scores. Mann-Whitney U Test for independent samples (at the kindergarten level) was employed to compare the change in lunch-box content across the controls. The results showed that in all the variables the difference between the intervention and the control kindergartens was significant, p< .002. It was concluded that the intervention had a significant positive impact on the content of the lunch boxes. This study shows the potential of supporting children to be change agents at home. In the future, there should be a follow-up of the family’s perseverance of the acquired habit.

支持儿童充当父母准备饭盒的变革代理

这项研究旨在检验“通过做改变营养”干预模式的效果，在这种模式中，儿童通过“做”来充当改变的推动者，负责他们提早带回家吃的午餐盒的内容童年中心。这项准随机病例对照试验由35个以色列幼儿园组成，这些幼儿园的老师正在参加一项干预模型的在职培训计划，以改善儿童的健康营养行为。对照组包括26所幼儿园，其教师正在参加其他在职培训方案。干预模型运行了八个月。实验组中儿童午餐盒内容的质量是在干预前和干预后通过结构化观察进行测量的，该观察产生了标准化的分数。采用Mann-Whitney U检验（独立样本）（在幼儿园水平）比较了对照组中午餐盒含量的变化。结果表明，在所有变量中，干预幼儿园与对照幼儿园之间的差异均很显着，p <.002。结论是，干预对午餐盒的内容产生了显着的积极影响。这项研究显示了支持儿童在家中成为变革推动者的潜力。将来，应该对家庭对所养成的习惯的坚持性进行跟进。p ＜.002。结论是，干预对午餐盒的内容产生了显着的积极影响。这项研究显示了支持儿童在家中成为变革推动者的潜力。将来，应该对家庭对所养成的习惯的坚持性进行跟进。p ＜.002。结论是，干预对午餐盒的内容产生了显着的积极影响。这项研究显示了支持儿童在家中成为变革推动者的潜力。将来，应该对家庭对所养成的习惯的坚持性进行跟进。
