This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. 16 We examined studies that explored the association between police exposures and health outcomes for Black youth 26 years and younger.
Literature Search StrategyWe searched the following databases on December 19, 2020: PubMed, Embase, Criminal Justice Abstracts, PsycInfo, and Web of Science (eFigure 1 in the Supplement). Search terms were developed by one of us (M.J.) with the assistance of a medical librarian and encompassed the following concepts: (1) police, (2) Black, and (3) health outcomes (eFigure 1 in the Supplement).
Study Selection and Data ExtractionFollowing removal of duplicates, 2 independent reviewers (M.J. and A.M.) performed title, abstract, and full-text screening as well as data extraction using Covidence software (Veritas Health Innovation). Included studies were peer-reviewed original research (quantitative or qualitative) conducted in the US and published between 1980, when community policing became prevalent, and December 2020. The study population was Black youth. Studies were included if participants 26 years and younger and 50% or more of the study population included Black participants or if there was a subgroup analysis of Black participants (ie, race stratification, with race as a modifier variable). For studies with less than 50% Black participants and race as a covariate, authors were contacted to request subgroup analyses. If subgroup analyses were not available, the study was excluded. Additionally, Hispanic/Latinx ethnic subgroups were excluded if Black race was not indicated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
