Abstract

We investigated the association of demographic and behavioral factors with oral human papillomavirus (HPV) load for 18 high-risk types among 211 individuals with prevalent high-risk HPV within the National Health and Nutrition Examination Survey 2009–2010. Factors independently associated with HPV load above the median included older age (odds ratio, 1.04 per year increase [95% confidence interval, 1.01–1.07]; P = .004) and intensity of current smoking (P for trend <.001). A marginally greater percentage of men than women had an HPV load above the median (55.7% vs 32.8%; P = .069), and HPV load increased marginally with increasing alcohol use (P for trend = .062). In conclusion, older age and current smoking are associated with a high oral load of high-risk HPV types among individuals with a prevalent infection.
