Multiple-type human papillomavirus infection in younger uncircumcised men.

ABSTRACT

A cohort of 388 young men enrolled for military service in the Danish army was established and the participants underwent a clinical examination with human papillomavirus (HPV) testing. In addition, a questionnaire containing questions regarding sociodemographic variables, sexual habits and lifestyle factors was completed. The prevalence of HPV was 33.4% in this cohort of uncircumcised men aged 18-29 years. Multiple HPV types were prevalent with one-third of the HPV-positive men being positive for more than one HPV type. Number of recent sexual partners and infrequent condom use were strong risk factors, particularly in men having multiple HPV types. Our findings re-emphasize the importance of sexual transmission and also point to a role of factors that may be related to individual susceptibility as genital warts, alcohol intake and, to a lesser extent, smoking were strongly associated with having multiple HPV types.
