Understanding of risk factors for the human papillomavirus (HPV) infection based on gender and race.

This study assessed if race and gender predict known sexual risk factors associated with HPV. Data (n = 301) were from a cross-sectional study conducted at a drag racing event on September 12-13, 2015 in Madison, Illinois. Both multivariable logistic and linear regression models estimated the association between race, gender, and sexual risk factors. About 63% of participants were males, and 65% identified as Blacks. Compared to females, males were more likely to have a higher number of oral sexual partners (OR = 2.10; 95% CI: 1.23, 3.57). Males were also more likely to have earlier oral sexual (b = -2.10; 95% CI: -3.60, -0.60) and vaginal sexual (b = -1.10; 95% CI: -1.69, -0.31) debuts compared to females. Blacks were more likely to have higher number of vaginal sexual partners (OR = 3.38; 95% CI: 1.81, 6.31) and earlier vaginal sex (b = -1.09; 95% CI: -1.78, -0.41) but less likely to have earlier oral sexual debuts compared with Whites (b = 2.67; 95% CI: 1.21, -4.13). Because HPV is associated with several cancers, our findings provide impetus for the development of targeted educational interventions aimed at improving the knowledge of these sexual risk factors, especially among men and across race groups.
