Abstract
Introduction: People in prisons are at high risk of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. The aim of this study was to evaluate the prevalence of HBV and HCV exposure and associated risk factors in Iranian prisons. Methods: This cross-sectional study was conducted in 2016, among 29 prisons in Iran, blood samples were collected using multistage sampling. HBV and HCV diagnostic tests were conducted using enzyme-linked immunosorbent assay (ELISA). Univariate and multivariate logistic regression were used for evaluation of factors associated with HBV and HCV exposure. Results: Among 6481 people in prisons, HCV and HBV antibody prevalence were 8.21% (95% CI: 7.55-8.90) and 3.06% (95% CI: 2.65- 3.50), respectively. In adjusted analysis, the most important risk factor for HCV exposure was history of injecting drug use (AOR 11.2, 95% CI 8.85- 14.18), followed by history of tattooing (AOR 2.02, 95%CI 1.56 – 2.60), history of imprisonment (AOR 1.61, 95%CI 1.21 – 2.14), being single (AOR 1.38, 95% CI 1.04 - 1.83), and low education (AOR 2.97, 95%CI 1.41 - 6.27). In adjusted analysis, no risk factors were found to be associated with HBV exposure. Conclusion: These findings highlight a high prevalence of HCV infection in Iranian prisons. Efforts are needed to improve HCV screening, particularly among people with a history of injecting drug use, and linkage to care.
