Abstract
IMPORTANCE: Understanding disparities in human papillomavirus (HPV) awareness is crucial, given its association with vaccine uptake. OBJECTIVE: To investigate differences in HPV awareness by educational attainment, race, ethnicity, and their intersectionality. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used the Health Information National Trends Survey (HINTS) 5 cycles 1 to 4 data (January 26, 2017, to June 15, 2020). The data were analyzed from December 12, 2022, to June 20, 2023. A sample of the noninstitutionalized civilian US population 18 years or older was included in the analysis. MAIN OUTCOMES AND MEASURES: Weighted prevalence of HPV awareness, HPV vaccine awareness, and knowledge that HPV causes cancer, stratified by educational attainment and by race and ethnicity. Interaction between educational attainment and race and ethnicity was assessed using a Wald test. RESULTS: A total of 15 637 participants had educational attainment data available; of these, 51.2% were women, and the median age was 58 (IQR, 44-69) years. A total of 14 444 participants had race and ethnicity information available; of these, 4.6% were Asian, 13.9% were Black, 15.3% were Hispanic, 62.6% were White, and 3.6% were of other race or ethnicity (including American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and more than 1 race or ethnicity). Awareness of HPV by educational attainment ranged from 40.4% for less than high school to 78.2% for college or higher; awareness by race and ethnicity ranged from 46.9% among Asian individuals to 70.2% among White individuals. Awareness of HPV vaccines across educational attainment ranged from 34.7% among those with less than high school to 74.7% among those with a college degree or higher and by race and ethnicity from 48.4% among Asian individuals to 68.2% among White individuals. Among adults who were aware of HPV, knowledge that HPV causes cervical cancer differed by educational attainment, ranging from 51.7% among those with less than high school to 84.7% among those with a college degree or higher, and by race and ethnicity, ranging from 66.0% among Black individuals to 77.9% among Asian individuals. The interaction between educational attainment and race and ethnicity on HPV awareness and HPV vaccine awareness was not significant; however, within each educational attainment level, awareness differed by race and ethnicity, with the lowest awareness consistently among Asian individuals regardless of educational attainment. Within each racial and ethnic group, HPV awareness and HPV vaccine awareness significantly decreased with decreasing educational attainment. CONCLUSIONS AND RELEVANCE: Disparities in HPV awareness were evident across social factors, with the lowest awareness among Asian individuals and individuals with lower educational attainment. These results emphasize the importance of considering social factors in HPV awareness campaigns to increase HPV vaccination.
