Statistical modeling the seroprevalence of hepatitis B among the pregnant women attending specialist hospital, Idah, kogi state, Nigeria

HBV infection among pregnant women in Idah was significantly associated with marital status, cultural practices (tribal marks), exposure to sharp objects, and multiple sexual partners. The predictive model demonstrated strong discrimination and calibration, supporting its potential utility for HBV risk stratification in antenatal care. However, modest specificity and NPV highlight the need for cautious interpretation and external validation in larger, multisite cohorts.
