Abstract
OBJECTIVES: Sex workers (SWs) face an increased burden of sexually transmitted and blood-borne infections, yet little is known regarding hepatitis B virus (HBV) prevention and care. This study was performed to characterize cross-sectional and prospective correlates of HBV vaccination among SWs in Vancouver. METHODS: Questionnaire data were drawn from a community-based cohort of SWs (2010-2017). Multivariable logistic regression was used to examine correlates of lifetime self-reported HBV vaccination. Multivariable generalized estimating equation (GEE) regression was used to assess correlates of recent vaccination. RESULTS: Among 855 participants, 68.3% reported lifetime HBV vaccination. Multivariable logistic regression showed that im/migrants (adjusted odds ratio (AOR) 0.50, 95% confidence interval (CI) 0.32-0.78) had lower odds of vaccination and that those using injection drugs (AOR 1.88, 95% CI 1.27- 2.78) and those who had undergone HIV testing (AOR 1.94, 95% CI 1.14-3.29) had higher odds of vaccination. In the multivariable GEE analysis, HIV seropositivity (AOR 1.93, 95% CI 1.26-2.97) and recent STI testing (AOR 2.95, 95% CI 1.99-4.39) correlated with recent HBV vaccination. CONCLUSIONS: Im/migrant SWs from HBV-endemic settings appear to face gaps in HBV prevention. Evidence-based interventions addressing gaps in voluntary HBV prevention and care are needed, including community-based and culturally safe services. Injection drug use and HIV testing were linked to enhanced vaccination, suggesting that harm reduction and HIV programmes may facilitate linkage to HBV prevention.
