Multivariate risk factors among males and females associated with ever performing oral sex, number of lifetime oral sex partners*, oral HPV infection and oral HPV16 infection.

*These analyses do not include data on 60–69 year old since number of lifetime oral sex partners were not collected in that age group.∧Mexican-American, Hispanic any race and other/multi-race individuals were combined into a single “other” race category for this model of predictors of oral HPV16 because of low numbers of oral HPV16 infections in these groups.
