Prevalence and Epidemiologic Profile of Oral Infection with Alpha, Beta, and Gamma Papillomaviruses in an Asian Chinese Population
BACKGROUND: Knowledge of the prevalence of and risk factors for oral human papillomavirus (HPV) infection, especially cutaneous types, is limited. METHODS: A population-based study using next-generation sequencing consecutively recruited asymptomatic individuals aged 18–64 years from a proportional...

Sumario: | BACKGROUND: Knowledge of the prevalence of and risk factors for oral human papillomavirus (HPV) infection, especially cutaneous types, is limited. METHODS: A population-based study using next-generation sequencing consecutively recruited asymptomatic individuals aged 18–64 years from a proportional sampling of the general population of Hong Kong, according to age groups, gender, and regions of residence. We examined associations of alpha-, beta-, and gamma-HPVs from oral rinse samples with participants’ sociodemographics by logistic regression models. RESULTS: The prevalence of oral HPV infection among 1426 ethnic Chinese was 15.5% (95% confidence interval [CI], 13.7%–17.5%), 2.5% (95% CI, 1.8%–3.5%), 11.9% (95% CI, 10.3%–13.6%), and 2.9% (95% CI, 2.1%–3.9%) for any type, alpha-, beta-, and gamma-HPV, respectively. Prevalence of any high-risk HPV was 0.8% (95% CI, 0.4%–1.4%), and that of HPV-16 was 0.4% (95% CI, 0.2%–0.8%). HPV-8 and HPV-98 were the most common beta types detected, while HPV-4 and HPV-SD2R were the most common gamma types. Prevalence of alpha- and beta/gamma-HPV infection showed a similar pattern of increase with age, and was higher in men than women. Smoking, drinking, oral sex, and more sexual partners were associated with alpha-HPV. Teeth brushing before sleep was protective for beta/gamma-HPVs. DISCUSSION: The epidemiologic factors associated with oral infection with alpha-HPVs are different from those of beta/gamma-HPVs, suggesting different modes of acquisition and persistence. |
