Evaluation of Seroprevalence and Factors Associated With the Portage of HBsAg in Pregnant Women in Rural Vanga and Semi-Urban Maluku

Context and objective: The diagnosis of viral hepatitis during pregnancy raises the problem of its seriousness in women but also fetal risk and mother-to-child transmission. The objective of this study was to determine the HBsAg screening rate and risk factors associated with HBs Ag transmission among pregnant women in semi-urban and rural areas of the Democratic Republic of Congo. Methods: Cross-sectional study of 152 pregnant women conducted from June 29, 2017 to April 28, 2018, having consulted the Gynecology and Obstetrics service of two medical units, one in the semi-urban environment of the city of Kinshasa and the other in the middle rural, chosen in a random way. HBsAg was wanted by a rapid test. The analysis was done with SPSS 22. A multivariate logistic regression model was used to search for risk factors for HBV at the p <5% threshold. Results: The mean age was 26.3 ± 7.1 years. The frequency of HBsAg was 15.8%. The risk factors associated with HBsAg were non-condom use (aOR: 2.26), transfusion (aOR: 3.49), multiple sexual partner (aOR: 2.39) and number of Risque Factor > 4 (aOR: 2.44). Conclusion: The frequency of HBsAg in pregnant women in the DRC is high. The national system of management and risk prevention factors for hepatitis B in pregnant women need to be strengthened.
