Background: Hepatitis B screening and vaccination have significant benefits in terms of mortality reduction, however, it is still underutilized among Vietnamese Americans, who continually suffer disproportionate HBV related liver cancer burden.

Objective: To assess the effectiveness of a multifaceted community-based participatory intervention on increasing hepatitis B screening and vaccination among medically underserved and low income Vietnamese Americans.

Methods: Vietnamese Americans (n=2,385) were recruited into the study from 36 Vietnamese community-based organizations. This group randomized intervention trial is guided by health belief model (HBM) and community-based participatory approach. Participating organizations were randomly assigned to receive either the HBM guided group education and discussion combining with patient navigation or a general cancer education. Study participants completed a baseline, post-intervention, 6-month and 12-month follow-up assessments.

Results: The intervention had significant impact on hepatitis B screening and vaccination at 6-month and 12-month post-intervention, respectively. During the 6-month follow-up, the rate of receiving hepatitis B screening for the intervention group (88.12%) was significantly higher than the control group (4.61%).  About two thirds of the participants (67.46%) who had HBV test and needed vaccination in the intervention group received all three recommended vaccination shots at the 12 month follow-up compared to 0% of participants in the control group.

Conclusion: The multifaceted community-based participatory intervention demonstrated the effectiveness in increasing hepatitis B screening and vaccination among medically underserved and low income Vietnamese Americans.
