Seroprevalence of hepatitis B and associated factors among inmates: a cross sectional study in the Douala New Bell Prison, Cameroon

Abstract

INTRODUCTION: In Cameroon, data on viral hepatitis B infection in prison environments is limited. We determined the prevalence of hepatitis B infection (HBV) and correlates among prisoners incarcerated at the Douala New Bell Central Prison in Cameroon. METHODS: this was a cross-sectional study carried out in July 2018 and included 940 randomly selected prisoners. Data were collected using pre-tested questionnaire while blood screening for HBV surface antigen (HBs Ag) used rapid test, with confirmation via Elisa test. Sociodemographic characteristics and risk factors were compared among the three age groups with respect to the prison´s partitioning. Factors associated with positive HBs Ag were identified using logistic regression adjusted to age and gender. Confounders were then excluded by logistic multivariate analysis. All p values less than 0.05 were considered statistically significant.
