{"doi":"10.1111/tmi.13531","title":"Hepatitis B infection and risk factors among pregnant women and their male partners in the Baby Shower Programme in Nigeria: a cross‐sectional study","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.","journal":"Tropical Medicine & International Health","year":2020,"id":79085,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":17,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9476,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":411256,"name":"Ijeoma Uchenna Itanyi","orcid":"0000-0002-4958-6319","position":1,"is_corresponding":false},{"id":411257,"name":"Kiyomi Tsuyuki","orcid":"0000-0002-9141-1395","position":2,"is_corresponding":false},{"id":238200,"name":"Nicole A.
