Knowledge of human papillomavirus and effects on sexual behaviour of gay/bisexual men: a brief report.

The objective of this study was to examine the knowledge and misinformation about human papillomavirus (HPV) and differences in sexual risk practices. Self-report surveys assessing the history of HPV/genital warts and sexual practices were completed by 1065 gay/bisexual men in New York City. Of the men reporting a history of HPV, genital warts, or both, the majority reported having warts but not HPV, demonstrating inaccurate knowledge. A significantly greater percentage of men who reported both HPV and warts (HPV+) reported having unsafe sex compared with men reporting neither (HPV-) and men reporting warts but not HPV (HPV+ uninformed). HPV+ and HPV+ uninformed men reported significantly more men non-primary sex partners in the past three months than HPV- men. Findings indicate that many gay/bisexual men, a population at risk for HPV, are misinformed about its various permutations. Men who are HPV+ report increased sexual risk practices and more sexual partners. Comprehensive gay men's health programmes must include HPV education.
