Age-Specific Global Prevalence of Hepatitis B, Hepatitis C, HIV, and Tuberculosis Among Incarcerated People: A Systematic Review

Abstract Purpose This study aims to compare the global prevalence of hepatitis B, hepatitis C, HIV, and tuberculosis in incarcerated adolescents and young adults (AYAs) and older prisoners. Methods This study is a systematic review and meta-analysis of studies reporting the age-specific prevalence of each infection in prisoners. We grouped age-specific prevalence estimates into three overlapping age categories: AYA prisoners ( Results Among 72 studies, there was marked heterogeneity in prevalence estimates among AYA prisoners for all infections: hepatitis B (.4%–25.2%), hepatitis C (.0%–70.6%), HIV (.0%–15.8%), and active tuberculosis (.0%–3.7%). The pooled prevalence of HIV (RR = .39, 95% confidence interval .29–.53, I 2  = 79.2%) and hepatitis C (RR = .51, 95% confidence interval .33–.78, I 2  = 97.8%) was lower in AYAs than in older prisoners. Conclusions The prevalence of HIV and hepatitis C is lower in AYA prisoners than in older prisoners. Despite lower prevalence, acquisition begins early among incarcerated populations. There is an urgent need for targeted, age-appropriate prevention, treatment, and harm reduction measures in and beyond custodial settings to reduce the incidence of infection in these extremely vulnerable young people.
