Description
Summary:The objective of this investigation was to study the prevalence of hepatitis B virus infection in a sample of 406 adult patients with human immunodeficiency virus infection who attended at the public health care in the city of Belém, Pará, Brazil, as well as analyzing possible risk factors for hepatitis B virus infection. The overall prevalence of hepatitis B virus infection was 51% (CI: 46.1 - 55.8), with 7.9% (CI: 5.3 - 10.5) for HBsAg, 45.1% (CI: 40.3 - 49.9) for anti-HBc and 32.3% (CI: 27.5 - 36.8) for anti-HBs. After adjustment using logistic regression, hepatitis B serological markers were associated with the following variables: age, marital status and sexual preference. The frequency of hepatitis B markers was 28.7% in heterosexuals and 68.8% in homo/bisexuals (CI: 3.50 - 9.08; OR: 5.63; p=0.000). In married people the frequency was 31% and 58.7% in single people (CI: 1.29 - 3.63); OR: 2.16; p=0.003). Multivariate analysis showed no association between hepatitis B virus infection and illicit injectable drug use.
