Results Differences in oral sexual behavior were observed by gender, age-cohort and race. 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 Conclusion 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.
Behavioral Data Demographic data was collected using an interviewer administered survey. Mexican-American, other Hispanic, non-Hispanic white, non-Hispanic black, and other race including multi-racial . 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. Statistical Analysis Analysis for this study was restricted to individuals 20—69 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. Wald F p-values were used to compare weighted prevalence between groups. For continuous variables, weighted means were compared using analysis of variance with Wald F p-values. The association of gender, age-cohort and race with odds of ever having performed oral sex was explored using multivariate logistic regression.
These models were adjusted for potential confounders including: With the exception of age-cohort, gender, and race, only covariates that were statistically significant were retained in the final multivariate models. Results Data from 2, men and 2, women between the ages of 20 and 69 were included in this analysis Table S1 in File S1.
