What the Task Force Found

About The Systematic Review

The Task Force finding is based on evidence from a systematic review conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to promoting good nutrition.

Context

There is no information for this section.

Summary of Results

Forty-five reports in forty-one studies qualified for the systematic review.

  • A wide variation was seen in:
    • Combinations of components (activities)
    • Length of study (< 3 months to 60 months)
    • Age of study population (K–12, median age 9.3 years; most students were in grades 3–5)
    • Length of follow-up period (55% immediate follow-up to 2% at 48 months)
  • Results were measured in terms of behavioral outcomes including changes in intake of fruit and vegetables, fat, and saturated fat.
  • Study outcomes were based on self-report of dietary intake, which is probably subject to reporting bias (e.g., social desirability—the possibility that answers may be influenced by what the respondent thinks is socially acceptable).
  • Although reported changes were in the desired direction, they were small and are questionable because of the potential bias of self-reports.
