Abstract

Objectives

To determine the population prevalence and determinants of hepatitis B (Hep B) status, and status discordance, among pregnant women and their male partners in Nigeria.

Methods

Cross-sectional study assessing the seroprevalence of Hep B virus in a cohort of 16 920 pregnant women and their male partners in northcentral Nigeria. Rapid HBsAg antibody test was used for Hep B diagnosis. Demographic, socio-economic and behavioural information was collected through interviewer-administered questionnaires and evaluated as determinants of Hep B status and couple status discordance using logistic regression.

Results

Of 16 920 participants who had a Hep B test result, 6750 couples and 1316 discordant couples were identified. The prevalence of Hep B among all participants was 10.9%, with lower prevalence among pregnant women (10.2%) than their male partners (11.9%), P < 0.001. The prevalence of Hep B sero-discordance among couples was 19.5% (1316/6750). Younger age, prior Hep B testing and a prior positive Hep B test increased the odds of Hep B infection while being a woman decreased the odds of Hep B among all participants, and among couples. Furthermore, polygamy (adjusted odds ratio [AOR]: 1.49, 95% confidence interval [CI]: 1.19-1.87), prior Hep B testing (AOR: 2.38, 95% CI: 1.14-4.97) and a prior positive Hep B test result were significant determinants of status discordance among the participating couples.

Conclusion

The prevalence of Hep B among pregnant women and their male partners in northcentral Nigeria is high. A large-scale intervention is required to reduce Hep B prevalence in this setting.
