Abstract

Our aim was to gain a better understanding of the knowledge about Human Papillomavirus (HPV) infection and attitudes toward the HPV vaccine among men at risk for sexually transmitted infections (STI). A self-administered questionnaire was completed by attendees of the largest STI Center in Rome, Italy, from April to June 2013. Determinants of vaccine acceptability were investigated using a Structured Equation Model. A total of 423 males participated in the survey: 296 (70.0%) men who have sex with men (MSM) and 127 (30.0%) men who have sex with women (MSW). Only one half of the participants knew that HPV is the cause of genital warts (56.9% of MSM vs. 49.5% of MSW, p=0.28). Even less were aware that HPV causes cancer in men (37.2% vs. 27.3%, p=0.08). MSW were more likely to indicate HPV as a cause of cervical cancer (80.8% vs. 69.3%, p=0.03) and to have heard about the vaccine (58.3 vs. 43.6%, p=0.01). Moreover, 72.1% of MSM and 70.3% of MSW were willing to be vaccinated. A rise of one-unit in the HPV awareness score increased the OR of vaccine acceptability among MSM by 25% (OR 1.25, 95%CI: 1.05–1.49; p=0.013). Differently, only attitudes had a relevant effect on willingness to be vaccinated among MSW (OR 3.32, 95%CI: 1.53–7.17; p=0.002). Efforts should be made to maximize awareness of HPV, especially as a causative agent of genital warts and male cancers, and to reinforce positive attitudes toward vaccination among men visiting STI centers.
