Hepatitis B knowledge, screening, and vaccination among Hmong Americans.

We examined Hmong women and men's knowledge of hepatitis B and their screening and vaccination behavior. In-depth interviews were conducted with Hmong in Oregon aged 18 and older (n=83). Independent samples t-test was used to assess mean differences in knowledge by demographic characteristics. Qualitative data were analyzed using content analysis. Most participants had heard of hepatitis B (96.4%). Fifty-three percent of participants had been screened, and half had been vaccinated (50.6%). Transmission knowledge was significantly higher among younger participants, those born in the U.S., and those who reported seeking preventive care. Sequelae knowledge was significantly higher among those who sought preventive care. Transmission and sequelae knowledge were not associated with screening and vaccination. Qualitative data showed that, of those hepatitis B positive participants, most did not have a comprehensive understanding of their illness. Intervention strategies should address knowledge deficits and improve health literacy, especially among Hmong who have hepatitis B.
