Obesity: Meal or Fruit and Vegetable Snack Interventions to Increase Healthier Foods and Beverages Provided by Schools

Effectiveness Review

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

The search strategy described below was used for the following reviews of interventions to support healthier foods and beverages in schools:

• Meal or fruit and vegetable snack interventions to increase healthier foods and beverages provided by schools
• Interventions supporting healthier snack foods and beverages sold or offered as a reward in schools
• Multicomponent interventions to increase availability of healthier foods and beverages in schools
• Interventions to increase water access in schools

The CPSTF findings are based on evidence from a systematic review published in 2013 (Wang et al, 2013) combined with more recent evidence. Wang et al. searched five bibliographic databases: MEDLINE®, EMBASE®, PsychInfo®, CINAHL®, and the Cochrane Library for relevant studies from their inception through April 22, 2013. The Community Guide systematic review team conducted an updated search for evidence through January 4, 2017. In the updated search for evidence, PubMed® was used instead of MEDLINE®, and a search was conducted using Clinicaltrials.com.

Search terms and search strategies were adjusted to each database, based on controlled and uncontrolled vocabularies and search software. Once the literature search was completed, Community Guide staff reviewed the citations using inclusion and exclusion criteria to narrow down the publications to be included.

Search Strategy - Economic Review

The published literature was searched for economic information about the two interventions that were found to be effective.

• Meal or fruit and vegetable snack interventions to increase healthier foods and beverages provided by schools
• Multicomponent interventions to increase availability of healthier foods and beverages in schools

The search for economic evidence included studies identified in the search for effectiveness evidence described earlier (search period through March 8, 2016) and a search within specialized databases at CRD-York and in EconLit (search period through January 5, 2016). Search terms and strategies were adjusted for each database, based on controlled and uncontrolled vocabularies and software. In addition, reference lists in included studies were screened and subject matter experts were consulted for additional studies that may have been missed.
