Multivariate logistic regression was used to evaluate predictors of oral sexual behavior and oral HPV16 infection. Differences in oral sexual behavior were observed by gender, age-cohort and race.
Most men Prevalence ratios PR of ever oral sex in men vs. In multivariate analysis, gender, age-cohort, and race were significant predictors of oral sexual behavior. Oral sexual behavior was the primary predictor of oral HPV16 infection; once this behavior was adjusted for, age-cohort and race were no longer associated with oral HPV There are differences in oral sexual behaviors when considering gender, age-cohort and race which explain observed epidemiologic differences in oral HPV16 infection across these groups.

In recent decades sexual behaviors have changed; the age of sexual initiation has decreased, and the lifetime number of sexual partners has increased. Therefore, we examined differences in sexual behaviors by gender, age-cohort, and race in a nationally representative sample, to explore whether the observed epidemiologic differences in oral HPV infection and OSCC rates reflect differences in sexual behaviors across these groups.
Demographic data was collected using an interviewer administered survey. Number of lifetime partners for any kind of sex, vaginal sex, and performing oral sex, were each collected separately. Number of lifetime partners reported in this paper is a sum of both male and female partners. Analysis for this study was restricted to individuals 20β69 yo, as the ACASI was not administered to older individuals. Weighted prevalence estimates were reported. The primary outcomes of interest were history of ever performing oral sex and number of lifetime oral sex partners.
