The aim of this study was to assess the effectiveness of a hepatitis B virus (HBV) educational program in increasing HBV knowledge.
Using a cluster randomized control trial to recruit participants from the community-based organization in the Baltimore-Washington Metropolitan Area; a total of 877 Asian American participants completed a self-administered pretest. HBV knowledge was the outcome measure. The intervention group received a 30-minute educational program. After the educational program, the intervention group completed a post-education survey. Six months after the education, all participants were followed by phone.
The intervention group showed significantly higher knowledge scores than the control group at the 6-month follow-up (between-group difference was 1.44 for knowledge of transmission modes and 0.59 for sequelae, p<0.01). For the intervention group, the increase in knowledge of HBV transmission modes in post-education was much higher than that at the 6-month follow-up (4.18 vs. 2.07), p<0.01) compared to baseline. Age was also an important factor on the educational effect: Those older than 60years reported the lowest scores in all three points.
Findings suggest that this culturally integrated liver cancer educational program increased HBV knowledge. Differential strategies are needed to target age groups, separately educating those younger and those older.
