INTRODUCTION: Globally, approximately 350-400 million persons are chronically infected with hepatitis B virus (HBV), over 65 million of whom are in Africa. One in four people with chronic hepatitis B develop serious health problems. Mother-to-child transmission (MTCT) is responsible for more than half of chronic infections. If infected at birth, a child has a 90% chance of becoming a chronic carrier. We evaluated hepatitis B virus prevalence and risk factors for infection among pregnant women attending antenatal clinics in West Hararghe public hospitals, Oromia region, Ethiopia.
METHODS: We conducted a cross-sectional study among 363 pregnant women at routine antenatal clinic visits in West Hararghe public hospitals from April-May, 2017. We used systematic random sampling method to enroll participants. We used a structured questionnaire to collect information on risk factors, and collected blood samples to test for hepatitis B Virus surface antigen (HBsAg) by enzyme-linked immunosorbent assay (ELISA). Data were entered using EpiData Version.3.1 and exported to SPSS Version 23.0 for descriptive analyses and binary logistic regression.
RESULTS: The overall seroprevalence of HBsAg among participants was 6.1% (95% CI 3.9-8.5). History of abortion (aOR=4.3, 95% CI 1.3-15.0), traditional tonsillectomy (tonsillectomy conducted by an untrained practitioner) (aOR=4.4, 95% CI 1.1-17.8), admission to a health facility (aOR=4.4, 95% CI 1.2-16.9), multiple sexual partners (aOR=6.3, 95% CI 1.7-23.4) and familial liver disease (aOR=8.2, 95% CI 2.1-32.8) were associated with hepatitis B virus infection among pregnant women.
CONCLUSION: The prevalence of hepatitis B virus in study area indicates a high-intermediate level epidemic. Multiple types of healthcare, as well classic risk factors such as multiple sex partners and a family history of liver disease increased the odds of infection. Hygiene promotion and infection prevention methods in healthcare settings are recommended to avoid nosocomial infections. To reduce MTCT, we recommended screening all pregnant women for hepatitis B virus as part of routine antenatal care and supportive treatment and making available methods of preventing infection at birth, including prophylaxis and birth dose vaccine.
