Prevalence and Determinants of Cervicovaginal, Oral, and Anal Human Papillomavirus Infection in a Population of Transgender and Gender Diverse People Assigned Female at Birth.

Purpose: The human papillomavirus (HPV) causes cervicovaginal, oral, and anogenital cancer, and cervical cancer screening options include HPV testing of a clinician-collected sample. Transgender and gender diverse (TGD) people assigned female at birth (AFAB) face many barriers to preventive care, including cancer screening. Self-sampling options may increase access and participation in HPV testing and cancer screening. This study estimated the prevalence of HPV in self-collected cervicovaginal, oral, and anal samples from Midwestern TGD individuals AFAB. Methods: We recruited TGD individuals AFAB for an observational study, mailing them materials to self-collect cervicovaginal, oral, and anal samples at home. We tested samples for high-risk (HR; 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) and other HPV genotypes (6, 11, 66, 68, 73, 90) using a polymerase chain reaction mass array test. Prevalence ratios for HPV infection at each site as a function of participant characteristics were estimated in log-binomial models. Results: Out of 137 consenting participants, 102 completed sample collection. Among those with valid tests, 8.8% (HR = 6.6%; HPV 16/18 = 3.3%) were positive for oral HPV, 30.5% (HR = 26.8%; HPV 16/18 = 9.7%) for cervicovaginal HPV, and 39.6% (HR = 33.3%; HPV 16/18 = 8.3%) for anal HPV. A larger fraction of oral (71.4%) than anal infections (50.0%) were concordant with a cervicovaginal infection of the same type. Conclusions: We detected HR cervicovaginal, oral, and anal HPV in TGD people AFAB. It is essential that we reduce barriers to cancer screening for TGD populations, such as through the development of a clinically approved self-screening HPV test.
