OBESITY IN PRISON: A META-ANALYSIS 123 Search Strategy Systemic steps used in this search followed the Preferred Reporting Items for Systematic Reviews and MetaAnalyses (PRISMA) guidelines (Fig. 1; Moher et al., 2009). Studies of interest included those reporting on BMI of incarcerated men and/or women in the United States. Databases were queried using a combination of keywords (e.g., ''obese OR obesity OR overweight OR BMI'' and ''prison OR prisoner OR jail OR incarceration OR inmate''). Keywords of the two categories were combined using the ''AND'' Boolean operator. PubMed, Web of Science, and Medline (OVID) databases were searched. Reference lists of relevant studies were searched. The full search strategy is available upon request. Inclusion and Exclusion Criteria Studies reporting on incarcerated adult males and females were included only if BMI or equivalent was documented and/or quantifiable weight change was specified. Studies that included actual assessment of weight changes were of primary interest. Additional inclusion criteria are publications in English; data collected from 1980 onward; and cross-sectional, cohort, and retrospective reviews. Exclusion criteria include studies on youth populations, Fig. 1. PRISMA flowchart indicating literature review search strategy.
