Hepatitis B vaccination prevalence and its predictors among Asian, Pacific Islander, Native American, and multiracial adults in the national health and nutrition examination survey

Hepatitis B Virus (HBV) vaccination prevalence and its predictors were estimated among Asian, Pacific Islander, Native American, and Multiracial (A-PI-NA-M) adults. Using 2005 National Health and Nutrition Examination Survey data, estimates of HBV vaccination among A-PI-NA-M adults (N = 233) were compared with all other racial/ethnic groups. Multivariable logistic regression was used to estimate predictors of vaccination. Among A-PI-NA-M adults 42% (95%CI 34, 50) were HBV immunized, higher than all other racial/ethnic groups. Some college was associated with a 31% (95%CI 7, 55); a college degree with a 28% (95%CI 8, 49) increased probability of HBV vaccination relative to less education. Each 10-year increase in age was associated with an 11% (95%CI -18, -4) lower probability of HBV vaccination. Access to medical care and immigrant status were not associated with vaccination. Interventions to increase HBV vaccination should target less-educated and older A-PI-NA-M adults, as well as develop strategies so that access to care may increase vaccination.
