Background: Probability and nonprobability-based studies of US transgender persons identify different disparities in health and health care access. Objectives:We used TransPop, the first US national probability survey of transgender persons, to describe and compare measures of health and health access among transgender, nonbinary, and cisgender participants. We directly compared the results with 2015 US Transgender Survey (USTS) data and with previously published analyses from the Behavioral Risk Factor Surveillance System (BRFSS).Methods: All participants were screened by Gallup Inc., which recruited a probability sample of US adults. Transgender people were identified using a two-step screening process. Eligible participants completed self-administered questionnaires (transgender n = 274, cisgender n = 1162). We obtained weighted proportions/means, then tested for differences between gender groups. Logistic regression was performed to evaluate associations. Bivariate analyses were conducted using the weighted USTS data set for shared variables in USTS and TransPop.Results: Transgender participants were younger and more racially diverse compared to the cisgender group. Despite equally high insurance coverage, transgender people more often avoided care due to cost concerns. Nonbinary persons were less likely to access transgender-related health care providers/clinics than transgender men and women. Transgender respondents more often rated their health as fair/poor, with more frequently occuring poor physical and mental health days compared to cisgender participants. Health conditions including HIV, emphysema, and ulcer were higher among transgender people. TransPop and USTS, unlike BRFSS-based analyses, showed no differences in health or health access.Discussion: Transgender persons experience health access disparities centered on avoidance of care due to cost beyond insured status. Health disparities correspond with models of minority stress, with nonbinary persons having distinct health/health access patterns. Despite different sampling methods, USTS and TransPop appear more similar than BRFSS studies regarding health/health access.

Background: HIV testing and pre-exposure prophylaxis (PrEP) are effective HIV prevention strategies often underused by transgender people. Methods: Recruitment occurred in 2 phases to identify transgender respondents in a probability sample of adults in the United States. Transgender respondents completed a self-administered paper or web-based survey designed to assess transgender population health. Sexually active respondents (HIV-negative and had sex in the 5 years previously, N = 190) and a subsample of those at risk for sexual HIV acquisition (sex with cisgender men or transgender women, n = 120) were included in analyses. Results: Of the full sample of sexually active respondents, those who were transfeminine were less likely to be familiar with PrEP; most (72%) reported favorable attitudes toward PrEP. Of those at risk for HIV acquisition, 23% had never tested for HIV. Respondents of color were more likely than white respondents to meet Centers for Disease Control and Prevention recommendations for HIV testing. Respondents who met Centers for Disease Control and Prevention recommendations for HIV testing were more likely to report looking online for lesbian, gay, bisexual, and transgender or transgender-specific health information. Few respondents reported currently taking PrEP (3%); those who reported higher levels of nonaffirmation of their gender identity were less likely to currently use PrEP. Discussion: These findings may indicate some success of HIV testing outreach programs that prioritize people at higher risk for acquiring HIV, focusing on those who are vulnerable to structural marginalization. Ongoing public health efforts are needed to increase HIV testing and PrEP awareness among transgender adults, who are disproportionately impacted by HIV.
