Objective: To determine the prevalence and barriers to human papillomavirus (HPV) vaccine uptake among 11-18 year olds in the Hawai'i's four major ethnic groups-Native Hawaiians, Filipinos, Japanese, and Caucasians. Study design: A telephone survey assessed parents' knowledge of HPV and the HPV vaccine, status of their child's HPV vaccine uptake, variables operationalizing the Health Belief Model, and barriers and motivators to uptake. Results: Across the groups, 799 parents completed the survey. About 35% of daughters and 19% of sons had received all three shots. Although ethnic differences in vaccine uptake were seen in bivariate analysis (with significantly lower uptake in Filipino youth), in multivariable logistic regression analysis, only Caucasian parents were significantly less likely to start their sons on the HPV vaccine series compared with Japanese parents (reference group). Having heard about the vaccine, believing in its effectiveness, and older age of the child were also associated with vaccine uptake. Motivators for HPV vaccination were physician's recommendation and wanting to protect one's child. The primary barrier to uptake was lack of knowledge about the vaccine. Conclusions: Findings reinforce the fact that a physician's recommendation and receipt of information about the vaccine are strong motivators for parents to vaccinate their children, regardless of ethnicity.
