Data from: Hepatitis B vaccination coverage, knowledge and sociodemographic determinants of uptake in high risk public safety workers in Kaduna State, Nigeria: a cross sectional survey

Objectives: To estimate hepatitis B vaccination (HBVc) coverage, and
knowledge and socio-demographic determinants of full-dose uptake in
Federal Road Safety Corps (FRSC) members, Kaduna State, Nigeria in order
to inform relevant targeted vaccination policies. Design: A
cross-sectional survey of FRSC members, Kaduna Sector Command. Settings:
Six randomly-selected Unit Commands under Kaduna Sector Command, Kaduna
State, Nigeria. Participants: Pilot-tested structured self-administered
questionnaire was administered to 341 participants aged 18 years and above
with ≥6 months of service between 17th June and 22nd July, 2015. Excluded
were FRSC members in Road Safety (RS) 1 Zonal Command headquarters as the
Zonal Command includes other States beyond the study scope. Primary
Outcome: HBVc status of participants categorized as ‘not vaccinated’ for
uptake of <3 doses and ‘vaccinated’ for uptake of ≥3 doses.
Analysis: Descriptive analysis estimated HBVc coverage while logistic
regression ascertained associations. Results: Most participants were
males, aged 30-39 years, with 3-10 years of service, and of Marshal cadre.
HBVc coverage was 60.9% for ≥1 dose and 30.5% for ≥3 doses. Less than 47%
of participants scored above the mean knowledge score for hepatitis B
virus (HBV) and HBVc. Female sex (AOR 2.28, 95% CI 1.15-4.52,
p<0.05), perceiving there to be an occupational risk of exposure to
HBV (AOR 2.86, 95% CI 1.06-7.70, p<0.001), and increasing HBVc
knowledge (AOR 2.68, 95% CI 1.83-3.92, p<0.001) were independent
predictors of full-dose HBVc in FRSC members, Kaduna Sector Command.
Conclusions: HBVc coverage and knowledge are poor among FRSC members,
Kaduna Sector Command. Educational intervention, geared towards improving
FRSC members’ knowledge of HBVc and perception of risk of occupational
exposure to HBV, is recommended for these vulnerable public safety
workers. Such enlightenment could be a cheap and easy way of improving
HBVc coverage in the study population.
