Abbreviations: HPV, human papillomavirus; PR, prevalence ratio.

^aAnalyses were conducted among 4964 participants aged 14–69 years who responded to the audio, computer-assisted self-interview.

^bPrevalence ratios and 95% CIs were estimated from binary logistic regression models with simultaneous adjustment for all variables in the table as well as age modeled as restricted cubic splines with 5 knots (age and 3 spline terms). P values for interaction of sex with each term were evaluated in separate models using product terms.

^cModels were restricted to male participants and included age modeled as restricted cubic splines with 5 knots (age and 3 spline terms), race, marital status, smoking, and lifetime number of any sex partners.

^dModels were restricted to female participants and included age (as a linear term), race, marital status, smoking, and lifetime number of any sex partners.

^eEver use of cigarettes was defined for individuals aged 14–19 years as ever having tried cigarettes and for ages 20–69 years as lifetime use of ≥100 cigarettes. A current smoker was defined as someone who had smoked a cigarette in the prior 30 days. A former smoker was defined as an ever user who had not smoked a cigarette in the prior 30 days.

^fP values for trend across categories were calculated through the use of ordinal variables modeled with 1 df.

^gLifetime number of any sex partners included the number of opposite-sex oral, anal, or vaginal sex partners.
