Background: To determine differences in the seroprevalence of high-risk human papillomavirus (hrHPV) types between men having sex with men (MSM), heterosexual men and women, we analyzed seroprevalence and risk factors for 8 hrHPV in the general population of Amsterdam, the Netherlands. Methods: We interviewed 1349 inhabitants aged [greater than or equal to]17 years and tested sera for antibodies against L1 capsid proteins of 8 hrHPV using Luminex-based multiplex serology. Risk factors for hrHPV were determined by multivariate Poisson analysis. Results: Seroprevalences for 8 hrHPV ranged from 13.1% for HPV-45 to 31.4% for HPV-35. Seropositivity for HPV-16 and HPV-18 was more common in women and MSM than in heterosexual men. HPV-16 and -18 were more common in subjects also having antibodies against other hrHPV types (prevalence rate ratio [PRR], 2.12, 95% confidence interval [CI] 1.52-2.97; and PRR, 2.00; 95% CI, 1.43-2.81, respectively) and/or herpes simplex virus type 2 (PRR, 1.69; 95% CI, 1.32-2.16; and PRR, 1.47; 95% CI, 1.13-1.92, respectively). HPV-18 was more common in persons with a history of sexually transmitted infections (STI) (PRR, 1.64; 95% CI, 1.20-2.25). HPV-35, -45, and -58 were more common in non-European ethnic groups. Conclusions: Prevalence of 8 hrHPV antibodies was high in the Amsterdam population, especially in MSM. DOI: 10.1097/OLQ.0b013e3181e71069
