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