Séroprévalence et facteurs associés à l'hépatite virale B chez les gestantes à Parakou en République du Bénin

The purpose of this study is to determine the seroprevalence and the factors associated with viral hepatitis B among pregnant women at the Departmental University Hospital of Borgou (CHUD-B).We conducted a cross-sectional descriptive and analytical study with prospective collection of data. It focused on pregnant women treated and/or having given birth at the CHUD-B from 1 April 2017 to 30 June 2017. The study included patients who gave their consent to participate in the study. The variables studied were the sociodemographic data of pregnant women and the result of HBsAg test. The detectionof HBsAg in blood sampling of pregnant women was performed using a biological test for rapid diagnosis. Positive results were confirmed by ELISA technique. Two hundred and fourteen (214) pregnant women were included in the study. The average age of patients was 26.73±5.68 years. The mean gestation age was 31 weeks of amenorrhea (WA) ranging from 4 WA and 42 WA. Among them, 30 women were positive for HBsAg, reflecting a prevalence of 14.02%. The factors associated with this colonization were the practice of scarification, a personal history of jaundice and family history of viral hepatitis B. The seroprevalence of viral hepatitis B among pregnant women at the CHUD-B is high. This best reflect this major public health problem due to Hepatitis B virus.
