Positive outcome expectancies mediated school nutrition intervention effects on children's fruit and vegetable consumption. Other factors like knowledge and self-efficacy showed potential but lacked statistical significance for mediation. Further research is crucial for effective school nutrition programs.

Area of Science:

  • Nutrition Science
  • Public Health
  • Behavioral Science

Background:

  • School-based nutrition interventions are vital for improving children's dietary habits.
  • Identifying mediators is key to understanding intervention effectiveness and optimizing program design.
  • Previous research has explored various factors influencing children's fruit and vegetable consumption.

Purpose of the Study:

  • To identify mediators of a school-based nutrition intervention targeting 4th graders and their parents.
  • To test nine potential mediators against four criteria for establishing mediation of intervention effects on fruit and vegetable consumption (FVC).

Main Methods:

  • A school-based intervention study involving 1,676 4th graders and their parents.
  • Fruit and vegetable consumption (FVC) measured via 24-hour dietary recalls in children.

  • Mediators assessed using questionnaires completed by children and parents.

    • Main Results:

    • Positive outcome expectancies met all four criteria for mediation.
    • Knowledge, self-efficacy, and parent consumption met the first three mediation criteria.
    • The mediating effects for knowledge, self-efficacy, and parent consumption were not statistically significant (Conclusion 4).

    Conclusions:

    • Positive outcome expectancies are a significant mediator of school-based nutrition interventions on children's FVC.
    • Further mediational analyses are needed to confirm the role of other potential mediators.
    • Developing a national database of mediators can enhance the strength and efficiency of school nutrition programs.
