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.

Within the family, children are important influencers of nutrition and exert their influence both in household food purchases and mealtime decisions. As such, children may use their influence to produce changes in food consumption for all family members. This study evaluated whether providing students with fruit and vegetables at school as part of a government-funded snack program would produce changes in family and household nutrition. Specifically, this study examined if the availability of fruit and vegetables at home could be increased through children requesting the same food served at school, as well as if parents would model the behaviour of eating more fruit and vegetables in front of their children. Results of this study found that providing children with fruit and vegetables at school did not increase the availability of fruit and vegetables at home or encourage parents to eat more fruit and vegetables in front of their children. However, strengthening the argument that children may influence family nutrition, children’s fruit and vegetable intakes were shown to influence parents’ intakes. These findings suggest that, instead of only providing fruit and vegetables to children, future nutrition initiatives should include additional components, such as hands-on activities and parental engagement.
