Oral human papillomavirus (HPV) prevalence and genotyping among healthy adult populations in the United States and Europe: results from the PROGRESS (PRevalence of Oral hpv infection, a Global aSSessment) study.

In multivariable analyses ( Table 4 ), oral HR-HPV risk among males was independently associated with age (AOR 1.04; 95% CI: 1.02–1.06); lifetime marijuana use (AOR 1.92; 95% CI: 1.19–3.11); higher number of lifetime oral sex partners (≥26), compared with no partners (AOR 2.10; 95% CI: 0.95–4.61), with an increasing trend with the number of partners; and residing in other countries compared with Spain, especially in the UK (AOR 2.89; 95% CI: 1.30–6.43).
