RESUMO

The hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in correctional settings have quite high prevalences, reaching rates of up to 40%. Several risk behaviors, adopted before or during the imprisonment, accounts for that. Among them, the use of intravenous illicit drugs, sharing of needles, tattoos and unprotect sexual activity are the most important. This survey aimed to estimate the prevalence of HBV and HCV serological marker and risk factors for these infections in men inmates at the Penitentiary of Ribeirão Preto, State of São Paulo, Brazil, between May and August 2003. Out of 1030 inmates, a simple random sample of 333 participants was chosen. The participants were interviewed in a standardized questionnaire and provided blood for serological tests. An enzyme-linked immunosorbent assay (ELISA) was used for diagnosis of HBV and HCV infection (HBsAg, anti-HBs, anti-HBc, anti-HCV). Polymerase chain reaction (HCV RNA) was used to confirm HCV infection. The overall prevalence for HBV and HCV markers in inmates was 19,5% (CI 95%: 15,2 - 23,8) and 8,7% (CI 95%: 5,7 - 11,7), respectively. The variables that displayed p<0,25, through univariate analysis, were assessed by a logistic regression multivariate model. At the level of 5%, HBV infection was associated with age >30 years and previous injecting drug use. For HCV infection, age >30 years, previous injecting drug use, previous sharing of needles, tattoos and previous hepatitis.
