IMPORTANCE In the US, oropharyngeal cancer, predominantly caused by high-risk (HR) human papillomavirus (HPV) infection, is the most frequent HPV-associated cancer, surpassing cervical cancer. However, little is known about oral HPV prevalence and genotype distribution in the general population. OBJECTIVE To assess oral HPV prevalence and factors associated with HR and low-risk infection in a general US population. DESIGN, SETTING, AND PARTICIPANTS PROGRESS (Prevalence of Oral HPV Infection, a Global Assessment) was a cross-sectional observational study conducted between November 2021 and March 2022 in 43 dental offices in the US (24 urban, 13 urban cluster, and 6 rural sites), spanning 21 states. Eligible participants were aged 18 to 60 years, visiting dental clinics for routine dental examination. Dental clinics used targeted sampling to recruit equal distributions of men and women and across age groups. EXPOSURE Participants provided an oral gargle specimen for HPV DNA and genotyping and completed behavioral questionnaires, and dentists reported oral health status. Detection of HPV DNA and genotyping was performed using the SPF10/DEIA/LiPA25 system at a central laboratory. MAIN OUTCOME Oral HPV prevalence. RESULTS Of the 3196 participants enrolled, mean (SD) age was 39.6 (12.1) years, and 55.5% were women. Oral HPV prevalence was 6.6%(95% CI, 5.7%-7.4%) for any HPV genotype, and 2.0% (95% CI, 1.5%-2.5%), 0.7%(95% CI, 0.4%-1.0%), and 1.5%(95% CI, 1.1%-1.9%) for HR, HPV-16, and 9-valent-HPV vaccine types, respectively. Among HPV-positive participants, HPV-16 was the most prevalent genotype (12.4% among men and 8.6% among women). Prevalence of HPV was higher in men than women and highest among men aged 51 to 60 years (16.8%, 6.8%, and 2.1% for any HPV, HR HPV, and HPV-16, respectively). Factors associated with HR oral infection included being male (adjusted odds ratio [AOR], 3.1; 95% CI, 1.2-8.5), being aged 51 to 60 years (AOR, 3.3; 95% CI, 1.5-7.3), having 26 or more lifetime male sex partners (AOR, 6.5; 95% CI, 2.3-18.7), and having 6 to 25 lifetime female oral sex partners (AOR, 3.4; 95% CI, 1.3-8.7). CONCLUSIONS AND RELEVANCE In this cross-sectional study, oral HPV burden was highest among older men who may be at higher risk of developing oropharyngeal cancer. In addition to male sex and older age, HR oral HPV infection was also associated with sexual behaviors, including increasing number of male sex partners and female oral sex partners.
