Aim: This study was aimed at determining the prevalence and associated risk factors for hepatitis B virus (HBV) infection among human immunodeficiency virus (HIV)-infected patients in a tertiary teaching hospital in Nigeria. Patients and Methods: Venous blood was collected from a total of 1680 (comprising of 1177 HIV infected and 503 non-HIV infected) patients and tested for the presence of HbsAg using immunochromatographic technique. Results: The seroprevalence of HBV among HIV and non-HIV-infected patients was 3.8% and 3.6%, respectively. HIV was not identified as a risk factor for HBV seropositivity (P = 0.919). A statistically significant association was found to exist between CD4 count <200 cells/mm3 and HBV seropositivity among highly active antiretroviral therapy-naïve HIV-infected patients (odds ratio [OR] = 10.085, 95% confidence interval [CI] = 1.314, 89.56, P = 0.008). HIV-infected males were observed to have a significantly higher prevalence of HBV infection (male vs. female: 6.1% vs. 3.1%; OR = 2.046, 95% CI = 1.103, 3.299, P = 0.029). Tribal mark was identified as a risk factor for HBV infection among HIV-infected male patients (P = 0.042). Conclusions: Male gender, presence of tribal marks, as well as CD4 count <200 cells/mm3 are risk factors for HBV infection among HIV-infected patients. Interventions by appropriate agencies are advocated.
