Existing knowledge, myths, and perceptions about hepatitis B and liver cancer within highly impacted immigrant communities.

Background: Immigrant groups from Southeast Asia, the Pacific Islands, sub-Saharan Africa, and the Caribbean bear the heaviest burden of chronic hepatitis B and primary liver cancer in the United States. Educational campaigns to increase knowledge about these diseases and their connection are necessary to promote protective health behaviors within these communities, to ultimately reduce the burden of disease, lessen stigma, and eliminate health disparities. Objectives: This project sought to engage groups within highly impacted communities to identify existing gaps in hepatitis B- and liver cancer-related knowledge, in order to inform future health education programming that will aim to reduce stigma and promote liver cancer prevention and early detection behaviors within and across groups. Methods: Fifteen focus groups and two key informant interviews were conducted virtually with participants from Micronesian, Chinese, Hmong, Nigerian, Ghanaian, Vietnamese, Korean, Somali, Ethiopian, Filipino, Haitian, and Francophone West African communities. Qualitative data were analyzed using thematic coding. Results: There are large gaps in knowledge and awareness of hepatitis B and liver cancer, and the link between these two diseases among Asian, Pacific Islander, African and Haitian immigrant communities. This limited knowledge and misinformation, exacerbated by stigma, hinder these groups' utilization of hepatitis B and liver cancer diagnostic and preventative healthcare services. Conclusion: To reduce hepatitis B and liver cancer health disparities within heavily burdened groups, health education needs to be community-informed, culturally sensitive, and actionable. Study results can guide the development of culturally and linguistically appropriate education programs that focus on the link between hepatitis B and liver cancer and the need for vaccination and routine screening, and that are responsive to the knowledge gaps and misperceptions of diverse communities. The results also provide valuable insights for healthcare providers to improve the knowledge gaps of the diverse patient populations that they serve.
