  • Assessment
    In school-based programs, what is the effectiveness of nutrition education as a part of an intervention program to address childhood overweight?
    • Conclusion

      There is insufficient evidence to draw conclusions about the effectiveness of school-based nutrition education interventions alone to address adiposity in children.

    • Grade: III
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    In school-based programs, what is the effectiveness of altering physical activity patterns as a part of an intervention program to address childhood overweight?
    • Conclusion

      The use of school-based physical activity programs alone is unlikely to bring about improvement in measures of adiposity in school-aged children.

    In school-based programs, what is the effectiveness of combined nutrition education and physical activity interventions to address childhood overweight?
    • Conclusion

      School-based programs that combined both a physical activity and a nutrition education component were diverse, combining different types of interventions for different lengths of time.

      Multi-component school-based programs that include at least physical activity and nutrition education interventions may be effective in improving adiposity measures, though results appear to be heavily dependent on a wide range of program design factors, population and context.

    Among systematic reviews that reported on anthropometric outcomes and also reported on behavioral outcomes of school-based interventions, what is the effectiveness of school-based physical activity programs for bringing about improvements in behaviors related to childhood overweight and obesity?
    • Conclusion

      Among systematic reviews that reported on anthropometric outcomes and also reported on behavioral outcomes, school-based physical activity programs alone may be successful in increasing time spent in physical activity and reducing screen time.

  • Intervention
    Among systematic reviews that reported on anthropometric outcomes and also reported on behavioral outcomes of school-based interventions, what is the effectiveness of school-based programs that include physical activity and nutrition education components for bringing about improvements in behaviors related to childhood overweight and obesity?
    • Conclusion

      Few systematic reviews that reported on anthropometric outcomes also reported on behavioral outcomes of school-based interventions that combined nutrition education and physical activity. However, among those that did, studies demonstrated improvement on at least one behavior associated with childhood overweight, such as increased physical activity, increased fruit and vegetable intake, decrease in sedentary behaviors, and so on
