Cross-sectional study assesses HBV infection prevalence and factors in pregnant women, highlighting public health implications.

The aim was to assess the prevalence of hepatitis B virus infection and associated factors among pregnant women in the Eastern Zone of Tigray.
Cross-sectional study among 536 pregnant women attending antenatal care in four public hospitals.
Data collected using a structured questionnaire and HBV infection status determined by a rapid test (HBsAg).
Bivariate and multivariable logistic regression analyses were performed to identify associated factors.
HBV infection prevalence was 7.8%, indicating high-intermediate endemicity.
Women aged ≥ 30 years were 2.72 times more likely to be infected (AOR = 2.72; 95% CI: 1.21–6.10).
A history of multiple sexual partners increased infection risk significantly (AOR = 16.12; 95% CI: 5.26–49.47).

Gebretsadik et al. (2026) studied this question.
