Abstract

We investigated the route of sexual exposure as a determinant for human papillomavirus (HPV)-16 and HPV-18 seropositivity. At the Amsterdam sexually transmitted infections clinic we recruited 4 risk groups: (1) men who have sex with women only (MSW; n = 751); (2) women who have sex with men (WSM; n = 749); (3) men who have sex with men (MSM) reporting insertive anal sex only (insMSM; n = 156); and (4) MSM reporting receptive anal sex (recMSM; n = 415). In multivariable analyses, HPV-16 seropositivity was significantly more common in WSM vs MSW, recMSM vs MSW, and recMSM vs insMSM. HPV-18 results were similar. Route of sexual exposure is independently associated with HPV seropositivity.
