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.
