Prevalence of and Risk Factors for Oral Human Papillomavirus Infection With Multiple Genotypes in the United States.

<bold>Background: </bold>This study investigated the prevalence of and risk factors for oral human papillomavirus (HPV) infection with multiple genotypes in the United States.<bold>Methods: </bold>Data were from the nationally representative 2009-2012 National Health and Nutrition Examination Survey. This analysis comprised 9257 participants for whom data on oral HPV (37 genotypes) and associated risk factors were available.<bold>Results: </bold>The weighted prevalence of multitype (2-6 types) oral HPV infection was 1.5% (2.5% for men, 0.4% for women) in the whole sample and 19.7% (22.0% for men, 12.1% for women) in those who had any type of oral HPV positivity. Most multitype oral HPV cases (83.8%) harbored one or more oncogenic types. In the adjusted multinominal logistic regression model, being male (relative risk ratio [RRR] = 3.69; 95% confidence interval [CI], 1.57-8.65), being a current cigarette smoker (RRR = 2.57; 95% CI, 1.23-5.36), and having a new sex partner in the past year (RRR = 2.10; 95% CI, 1.03-4.28) were associated with an increased risk of multitype oral HPV infection over single-type HPV infection.<bold>Conclusions: </bold>Men, smokers, and those who had new sexual partners were at a significantly higher risk for multitype oral HPV infection.
