Hepatitis B and liver cancer among Hmong in Oregon: Knowledge, perceptions of risks, and barriers to hepatitis B screening and vaccination

Background: Chronic hepatitis B disproportionately affects Asian Americans; although Asians make up only 4.2% of the total United States (U.S.) population, they account for more than half of those infected with hepatitis B. Studies show that the Hmong population, who emigrated from Southeast Asia where hepatitis B is endemic, have a high prevalence of hepatitis B, yet knowledge of hepatitis B infection and vaccination rates is low. Objective: Our objectives were to examine (1) knowledge, attitudes, and beliefs about hepatitis B infection and its transmission, (2) misconceptions of liver cancer; and (3) perceptions of risks for hepatitis B infection and barriers to screening and vaccination among Hmong living in Oregon. Methods: We used a mixed methods approach to collect data from Hmong men and women. We have conducted 17 key informant interviews with Hmong community leaders and other community members interested in Hmong health. We are currently conducting 80 in-depth interviews. Results: From our key informant interviews, we learned that Hmong in Oregon lack knowledge of hepatitis B and liver cancer, and that cultural, social, and linguistic factors are potential influences on hepatitis B screening and vaccination behavior. Results from the in-depth interviews are forthcoming and will also be presented. Discussion: Learning about the factors that influence knowledge and attitudes towards hepatitis B and identifying the barriers to screening and vaccination for the Hmong are important, especially in a state such as Oregon where few culturally appropriate services and resources exist.
