Assessing Hepatitis B Knowledge Among Native Hawaiians and Pacific Islanders in San Diego

BACKGROUND: Asian-Americans and Pacific Islanders comprise 6% of the U.S. population, but 50% of chronic hepatitis B cases and have a cancer mortality that is 60% higher than non-Hispanic Whites. The objective of this study was to assess knowledge of HBV transmission, symptoms/sequelae and treatment among NHPIs in San Diego. METHODS: Self-administered surveys were distributed using convenience sampling at the 24th Annual Pacific Islander Festival in San Diego in 2018. RESULTS: Overall knowledge scores were low (mean: 9.8 out of 28) among participants. Compared to U.S.- born (mean: 11.6), participants born in Pacific Island countries and territories (mean: 8.5) had lower knowledge scores (p = 0.017) and lower self-reported vaccination rates (50% vaccinated vs 27%, respectively, p = 0.025). DISCUSSION: Lack of HBV knowledge, low vaccination rates and the discordance between knowledge and behavior regarding HBV vaccination elicits an urgent need to collaborate with NHPI communities for HBV education, screening, immunization and treatment.
