Social media-based intervention to promote HBV screening and liver cancer prevention among Korean Americans: Results of a pilot study

Abstract

Objective In United States, Asian Americans are 10 times more likely to have hepatitis B virus (HBV) infection than Whites. Asian immigrants with limited English proficiency face extra barriers to HBV screening and many are unaware of the infectious status. This study aimed to evaluate a social media-based intervention to promote HBV screening and liver cancer prevention among Korean Americans (KA) with limited English proficiency. Methods Our community-academia partnership developed the “Lets talk about liver cancer” mHealth program by adapting a CDC media campaign. The program consisted of culturally tailored short video clips and pictorial messages and was delivered over 4 weeks to the participants via the popular Korean social media app, Kakao Talk. A total 100 KA living in greater Washington DC metropolitan were recruited via social media networks and completed this pre-post pilot study. Results Out of the 100 participants of KA, 56 were female, mean age was 60, and most have lived in the U.S. for more than 20 years, 84% had limited English proficiency, and 21% had a family history of HBV infection or liver cancer. After 4-week intervention, 95% completed the follow-up survey. Participants reported significant improvements in HBV-related knowledge, liver cancer prevention knowledge, perceived benefits of HBV testing, perceived risks of HBV infection, injunctive norms of HBV testing, and self-efficacy of HBV testing. Conclusions The Kakao Talk-based liver cancer prevention program for KAs was feasible and effective. We advocate for community-academia partnership to develop and implement culturally appropriate and social media-based interventions for underserved immigrants.
