Multilevel factors influencing hepatitis B vaccination among Vietnamese Americans
Methods: Venue-based sampling was utilized to survey 316 persons ages <18 years from diverse community locations. Bivariate and multivariate analyses assessed the impact of individual, dyadic-(patient/physician), and community-level factors on HBV vaccination. We also performed an exploratory principal components factor analysis and evaluated corresponding internal consistencies of resulting factors.
Results: This study found that less than 50% (n=146) of the sample population received at least one dose of HBV vaccine. Internal consistencies demonstrated high levels of reliability for scaled items included in the multivariate vaccination model(Cronbach alpha = 0.76-0.89). The bivariate model accounting for individual-, dyadic- and community-level factors revealed that HBV vaccination intent was associated with age <42 years (OR=0.96), perceived social approval (OR=1.57), physician approval (OR=1.57), and community recommendation (OR=1.46). Similarly, among those who received at least one dose of HBV vaccine, vaccination was associated with age <42 years (OR=0.94), perceived social approval (OR=1.30), community recommendation (OR=1.74), and disbelief in Hepatitis B vaccination myths (OR=0.52).
Conclusions: The findings support the hypothesis that multiple-level factors facilitate HBV vaccination in this population. Tailored, culturally-appropriate communication strategies for targeted age groups will positively influence greater immunization uptake. The importance of healthcare provider recommendation of HBV vaccine are highlighted.

Keywords: Hepatitis B, Immunizations
Qualified on the content I am responsible for because: I have been the principal investigator of multiple federally and privately funded grants focusing on vaccine acceptance and refusal in racially and ethnically diverse communities. I served as the lead behavioral investigator for this study which was funded by a federal supplement to the ACTSI award. My work therefore entailed engagement with the Vietnamese community on issues related to Hepatitis B prevention including understanding barriers to increasing vaccination for intervention development.
