Awareness and knowledge of Human Papillomavirus (HPV) infection among high-risk men of Hispanic origin attending a Sexually Transmitted Infection (STI) clinic

Background: Genital Human papilloma virus (HPV) is one of the most commonly diagnosed Sexually Transmitted Infection (STIs) in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico. Methods: A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p<0.05) were included in the multivariate logistic regression model. Results: Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%), penile (50.0%) and oral (72.6%) cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM) (OR=2.6; 95% CI=1.1-6.1), self-report of genital warts (OR=3.2; 95% CI=1.3-7.9) and herpes (OR=7.4; 95% CI=2.2-25.1). MSM was marginally associated with adequate knowledge (OR=2.3; 95% CI=0.9-5.9) and self-report of herpes remained significantly associated (OR=5.0; 95% CI=1.3-18.4) in multivariate logistic regression analysis. Conclusions: Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.
