Abstract

BACKGROUND: World Health Organization recommends hepatitis B vaccine birth dose for all infants within 24 hours of birth as the most cost-effective measure to prevent perinatal hepatitis B virus infection (HBV). We assessed and identified the predictors of maternal knowledge and infants' uptake of valid hepatitis B vaccine birth dose (HepB-BD).

METHODS: We conducted a hospital-based cross-sectional survey among 344 mother-infant attendees of routine immunization clinics selected by multi-stage sampling technique in Enugu State, Nigeria. We collected data on socio-demographic characteristics, delivery history, maternal knowledge and infant's receipt of valid HepB-BD with interviewer-administered questionnaire. Maternal knowledge was assessed using nine domain questions. Overall, good knowledge was defined as a score of ≥50%. Only infants who received first hepatitis B dose within 24 hours were considered to have received valid BD. We calculated frequencies, performed Chi square test and logistic regression.

RESULTS: One hundred and two (29.7%) mothers knew HBV can be transmitted from mother to child; 119 (34.6%) and 156 (45.3%) knew their infant should receive valid HepB-BD and four doses for full immunization of HepB respectively. Overall, 114 (31.1%) mothers had good knowledge of HBV and 88 (26.9%) of 327 who delivered at the health facilities had valid HepB-BD. Predictors of maternal knowledge were attainment of tertiary education (adjusted Odds Ratio (aOR): 2.1, 95%CI: 1.3-3.5) and living in rural areas (aOR: 0.5, 95%CI: 0.3-0.9). Predictors of valid HepB-BD uptake were maternal knowledge (aOR: 2.4, 95%CI: 1.4-4.0) and delivery at facilities offering routine immunization services (aOR: 5.4, 95%CI: 2.5-11.9).

CONCLUSION: Knowledge and uptake of valid HepB-BD were low. Health education on benefits of valid HepB-BD was given to mothers after administration of questionnaires. We disseminated findings to the State Ministry of Health and recommended integration of child delivery and immunization services for birth dose vaccines especially valid HepB-BD.
