Research provides evidence of take-home effects in school-based nutrition interventions, citing children as important influencers of family nutrition, acting as agents of change in the household and potentially influencing family food consumption. Therefore, the purpose of this randomized control trial was to examine whether implementation of a centrally procured school food program would produce changes in children's home food environment, including fruit and/or vegetable availability and parental modelling of fruit and/or vegetable consumption. A secondary objective was to investigate whether children's fruit and/or vegetable intake predicted their parent's fruit and/or vegetable intake. A total of 60 schools participated in the evaluation, including 2443 students (and their parents) in grades 5-8. Findings indicated that the intervention did not produce take-home effects on children's home availability of fruit (p = 0.52) and vegetables (p = 0.67) or parental modelling of fruit (p = 0.26) and vegetable consumption (p = 0.78), which may be related to the fact that only food provisions were given. However, children's fruit and vegetable consumption predicted parents' fruit and vegetable consumption (p < 0.001), thereby indicating that children may possess the capacity to influence home nutrition. Future school-based nutrition interventions are recommended to be multi-component (e.g. experiential learning, parent involvement) and that encourage nutrition leadership opportunities for children in the home context.
研究为基于学校的营养干预措施中的“带得走的效果”提供了证据，认为儿童是家庭营养的重要影响者，他们在家庭中充当着变革的推动者，并可能影响家庭的食物消费。因此，本随机对照试验的目的是检验集中采购的学校食品计划的实施是否会改变儿童的家庭食物环境，包括水果和/或蔬菜的供应情况以及父母对水果和/或蔬菜消费的示范作用。次要目标是调查儿童的水果和/或蔬菜摄入量是否可以预测其父母的水果和/或蔬菜摄入量。共有 60 所学校参与了评估，其中包括 5-8 年级的 2443 名学生（及其父母）。研究结果表明，干预措施并未对儿童家庭水果（p=0.52）和蔬菜（p=0.67）的供应以及父母对水果（p=0.26）和蔬菜消费（p=0.78）的示范作用产生“带得走的效果”，这可能与仅提供食物供应有关。然而，儿童的水果和蔬菜摄入量可以预测其父母的水果和蔬菜摄入量（p<0.001），这表明儿童可能有能力影响家庭营养。建议未来的基于学校的营养干预措施采取多组分（例如体验式学习、家长参与）的方式，并鼓励儿童在家庭环境中获得营养领导机会。
