As hepatites B e C na população carcerária feminina do Pará: prevalência, genotipagem e fatores de risco

Abstract

The characteristic of high-risk behavior from the prison public contributes for a high prevalence of diseases transmitted by sexual or parenteral route. Considering the high rates of hepatitis B and C in prisons, this study aims to identify the main risk factors, the prevalence of these diseases and the founded genotypes. This study is an analytical cross-sectional. The sample was composed of 313 inmates from the Female Recovery Center in the State of Pará, wich agreed to participate of this study and were in good physical and mental health. Blood samples were collected and applied a socio-epidemiological questionnaire. The socio-epidemiological analysis showed a predominance of the age group 25-34 years (44.8%), marital status single (55%), incomplete elementary school education (68%) and 1 minimum family wage (65% ). The variables of age and education showed a statistically significant correlation with markers of HBV infection. Risk factors such as cutting and piercing material sharing, tattoo, hospitalization, dental surgery and not condom use showed high frequency. The variable of hospitalization showed statistics association with markers of HBV infection. Serology by ELISA assay showed that 3% were positive for HBsAg, 15% reagents for Anti-HBc, 23% reagents for anti-HBs and 5% for anti-HCV. In the genotyping of samples was found wich from of 10 HBsAg positive samples, 4 samples had undetectable genotype, in 5 samples the genotype E was identified (still not mentioned in Brazil), and in 1 was identified the genotype F (third most prevalent the country) ; from the 17 positive samples for Anti-HCV, 41.2% had undetectable genotype, this same percentage was obtained for genotype 1, and in 17.6% of samples was found the genotype 3, in agreement with the Brazilian standard described in literature.
