Seroprevalence of Hepatitis B virus infection and associated factors among pregnant women at Korle-Bu Teaching Hospital, Ghana.

INTRODUCTION: Hepatitis B virus infection is a global public health problem. Though, the disease is endemic in sub-Saharan Africa, little is known about its epidemiology among pregnant women in Ghana. This study sought to determine the seroprevalence of Hepatitis B virus infection and associated factors among pregnant women attending antenatal care at Korle-Bu Teaching Hospital; Ghana's largest hospital. METHODS: We conducted a facility-based cross-sectional survey among 232 antenatal attendants. Participants were recruited using systematic random sampling technique and screened with HBsAg Rapid Test. Data was analyzed with the aid of Statistical Package for Social Sciences (SPSS), version 23.0. Results were presented using descriptive statistics, Fisher's Exact test and Logistic Regression analysis. RESULTS: Two hundred and twenty-one (221) of the total sample (n = 232) agreed to participate in this study; representing a response rate of 95%. The mean age of the participants was 31 years and standard deviation of 5.3. The mean gestational period at recruitment was 28 weeks and standard deviation of 6.8. Majority of the participants were married (83.3%), parous (69.6%), educated (91.4%) and employed (90.5%). The prevalence of HBsAg was 7.7%. We found no significant association between socio-demographic characteristics of the participants and HBV infection. CONCLUSION: Seroprevalence of 7.7% indicates moderate endemicity. Socio-demographic characteristics did not influence HBV infection among pregnant women attending antenatal care at Korle-Bu Teaching Hospital. The findings provide empirical evidence that will contribute to knowledge of HBV epidemiology in Ghana.

Hepatitis C virus seroprevalence among mothers delivering at the Korle-Bu Teaching Hospital, Ghana.

OBJECTIVES: To determine the Hepatitis C virus (HCV) carrier rate among mothers, and to determine if selected sociodemographic characteristics are associated with HCV seropositivity. DESIGN: Maternity Unit of the Korle-Bu Teaching Hospital (KBTH). SETTING: A cross-sectional serological survey of mothers delivering at the KBTH. METHODS: Women who had singleton live births and fresh stillbirths in the two labour wards of the KBTH were randomly selected for screening from 1st March to 30th September, 2001. A structured pre-tested questionnaire was used by trained research assistants to collect and record data on medical and sociodemographic characteristics of the subjects. Maternal blood samples were taken and stored at the Public Health Reference Laboratory. The second generation Murex diagnostics ELISA kit was used to test the maternal sera for HCV antibodies. RESULTS: Sixteen (2.5%, 95% CI, 1.5-4.1%) of the 638 subjects were HCV seropositive. None of the medical and sociodemographic characteristics examined showed any association with HCV seropositivity. No subject or her sexual partner was a drug injector. CONCLUSION: The carrier rate of 2.5% of HCV infection found in this study is near the top end of the range found in unselected pregnant populations from other parts of the world. Knowing the prevalence rate of HCV infection in our pregnant population will help policy-makers on the cost effectiveness of available intervention measures.
