Abstract
Our study identifies the prevalence of HBV virus (HBV) screening and vaccination among Asian Americans, and ethnic differences for factors associated with screening and vaccination behaviors. In 2009–2010 we recruited 877 Korean, Chinese, and Vietnamese Americans 18 years of age and above through several community organizations, churches and local ethnic businesses in Maryland for a health education intervention and a self-administered survey. Prevalence of HBV screening, screening result and vaccinations were compared by each ethnic group. We used logistic regression analysis to understand how sociodemographics, familial factors, patient-, provider-, and resource-related barriers are associated with screening and vaccination behaviors, using the total sample and separate analysis for each ethnic group. Forty-seven percent of participants reported that they had received HBV screening and 38% had received vaccinations. Among the three groups, the Chinese participants had the highest screening prevalence, but lowest self-reported infection rate; Vietnamese has the lowest screening and vaccination prevalence. In multivariate analysis, having better knowledge of HBV, and family and physician recommendations was significantly associated with screening and vaccination behaviors. Immigrants who had lived in the US for more than a quarter of their lifetime were less likely to report ever having been screened (OR = 0.39, 95% CI: 0.28–0.55) or vaccinated (OR = 0.62, 95% CI: 0.44–0.88). In ethnic-specific analysis, having a regular physician (OR = 4.46, 95% CI: 1.62–12.25) and doctor’s recommendation (OR = 2.11, 95% CI: 1.05–4.22) are significantly associated with Korean’s vaccination behaviors. Health insurance was associated with vaccination behaviors only among Vietnamese (OR = 2.66, 95% CI: 1.21–5.83), but not among others.
