Seroprevalence of HBV, HCV, and HIV and Associated Risk Factors Among Apparently Healthy Pregnant Women in Anyigba, Nigeria.

Abstract

Globally, infection of pregnant women by human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) pose a significant health challenge for not just the mothers but also the newborn infant. This study was undertaken to assess the prevalence of HIV, HCV, and HBV among pregnant women attending antenatal clinic in Kogi State University Teaching Hospital (KSUTH), Anyigba, Nigeria. Sera samples obtained from 200 consented pregnant women were screened for hepatitis B surface antigen (HBsAg), anti-HCV, and anti-HIV antibodies using commercially available immunoassay test kit. Demographic variables and obstetric characteristic were obtained using structured questionnaire. Of the 200 sera tested, the seroprevalence rates were 1.0%, 0.5%, and 8.5% for HBsAg, anti-HCV, and anti-HIV antibodies, respectively. Although 0.5% were coinfected with HIV/HCV, none was simultaneously infected by the three viruses. Age, marital status, trimester, and educational and occupational status did not significantly affect the prevalence of HIV, HCV, and HBV infections. However, factors such as history of abortion/miscarriage (p = 0.04), intravenous drug use (p = 0.001), and history of other sexually transmitted infection (p = 0.01) were significantly higher in relation to HIV seropositivity. In conclusion, findings from this study revealed high HIV seroprevalence and a clear decline of hepatitis C and B infection prevalence compared with previous epidemiological data. Reason for the latter could be attributed to the current efforts to reduce mother-to-child transmission and possible HBV vaccination programs. High burden of HIV infection in our study suggests the needs to strengthen the national prevention programs including education of the people on the risk factors of HIV transmission.
