Background: Human papillomavirus (HPV) prevalence is high among men who have sex with men (MSM), yet little is known about HPV among transgender women (TGW). We assessed HPV prevalence and knowledge among TGW compared with MSM., Methods: We enrolled TGW and MSM aged 18 to 26 years from clinics in Chicago and Los Angeles during 2012 to 2014. Participants self-reported gender identity, HIV status, HPV knowledge, and vaccination status. Self-collected anal and oral specimens were tested for HPV DNA (37 types); serum was tested for HPV antibodies (4 vaccine types). Prevalence among unvaccinated TGW and MSM was compared using prevalence ratios (PRs) and 95% confidence intervals (CIs). Participants without DNA or serologic evidence of HPV were considered naïve., Results: Among 1033 participants, 49 were TGW. Among 44 TGW and 855 MSM who were unvaccinated, any HPV DNA was detected in anal specimens from 39 (88.6%) TGW and 606 (70.9%) MSM (PR, 1.3; 95% CI, 1.1-1.4), and oral specimens from 4 (9.1%) TGW and 81 (9.5%) MSM (PR, 1.0; 95% CI, 0.4-2.5). Antibodies were detected among 37 (84.1%) TGW and 467 (54.6%) MSM (PR, 1.5; 95% CI, 1.3-1.8). Most participants were naïve to 1 or more HPV vaccine type/s, including 29 (65.9%) TGW and 775 (90.6%) MSM (PR, 0.7; 95% CI, 0.6-0.9). Most TGW (55.1%) had never heard of HPV vaccine., Conclusions: Among TGW, HPV prevalence was high and knowledge was low. Most were still naïve to 1 or more HPV vaccine type. Although vaccination ideally occurs prior to exposure, findings support existing national recommendations to vaccinate TGW and MSM, and suggest additional outreach might increase vaccination.

Background: Men who have sex with men (MSM) are at high risk for sexually transmitted infections (STIs). National guidelines recommend that MSM receive HIV, syphilis, gonorrhea, and chlamydia screening at least annually, and hepatitis A and B and human papillomavirus vaccinations. We investigated associations between disclosure of male-male sexual orientation/behavior and receipt of this panel of services., Methods: Gay, bisexual, and other MSM aged 18 through 26 years were enrolled from health clinics serving lesbian, gay, bisexual, and transgender communities in Los Angeles and Chicago during 2012 to 2014. Participants completed a computer-assisted self-interview regarding health care services, disclosure of sexual orientation/behavior, and recent HIV test results. Proportions receiving recommended care, prevalence ratios (PRs), and 95% confidence intervals (CIs) were calculated using SAS 9.4., Results: Overall, 817 participants visited a provider within the past year. Of these, 525 (64.3%) had disclosed, and 749 (91.7%) felt they could disclose if important to health. In total, 548 (67.1%) received all STI screenings, and 74 (9.1%) received all vaccinations. Only 105 (12.9%) received any human papillomavirus vaccination. More disclosing participants received all recommended screenings (adjusted PR [aPR],1.4; 95% CI, 1.3-1.6) and all recommended care components (aPR, 2.2; 95% CI, 1.4-4.3) than nondisclosing participants., Conclusions: Despite national recommendations, receipt of a complete panel of STI care services was low among young MSM. Vaccine uptake was lower than STI screening. However, most participants visited a health care provider in the past year and most disclosed, suggesting opportunities to improve services. Providers might encourage disclosure by improving sexual history taking and education, which could increase opportunities for MSM to receive recommended care.
