Health and health care access in the US transgender population health (TransPop) survey.

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).
