Abstract
OBJECTIVES: To investigate the differences in oral HPV infection and sexual behaviors by race in the US. MATERIALS AND METHODS: We analyzed data from the 2011-2014 US National Health and Nutrition Examination Survey during which participants aged 18-69 years completed oral rinse exam for HPV detection (n = 8,229). Logistic regression was used to examine the associations of race with various types of oral HPV infection and sexual behaviors. RESULTS: The prevalence of overall oral HPV infection and HPV type16 infection was 7.5% [95% CI: 6.6-8.4] and 1.1% [95% CI: 0.7-1.3], respectively. Blacks were more likely to have any oral HPV infection [OR: 1.22, 95% CI: 1.01-1.47] and Asian Americans were less likely to have any oral HPV infection [OR: 0.33, 95% CI: 0.24-0.49] than Whites. In a multivariate model, Whites were less likely to have any oral HPV infections than Blacks while having higher order of impact by the number of lifetime sex partners. Overall, Asian Americans were less likely to have type16 infection [OR: 0.21, 95% CI: 0.06-0.67] than Whites; however, that difference disappears when adjusting for sexual behaviors. CONCLUSIONS: In this nationally representative sample of US adults, the prevalence of overall oral HPV infections was higher among Blacks and lower among Asians in comparison to Whites. Further analysis with sexual behavior data suggested that the racial differences in prevalence are likely due to different sexual behaviors.
