The Impact of Gender Affirming Medical Care During Adolescence on Adult Health Outcomes Among Transgender and Gender Diverse Individuals in the United States: The Role of State-Level Policy Stigma.

Gender affirming medical care (GAMC) aims to alleviate gender dysphoria by helping people align their physical body more closely with their gender identity. Bills seeking to limit or prohibit GAMC for trans children and adolescents have become a controversial topic. This study aimed to examine whether exposures to GAMC during adolescence are associated with adult psychological and general health outcomes, and to demonstrate the mechanism through which state-level legislation may work to moderate the association. We conducted analyses using data from the 2015 U.S. Transgender Survey, which surveyed 27,715 transgender and gender diverse (TGD) adults between August and September of 2015. The study compared the health outcomes of those who had GAMC exposures during adolescence with those who did not. Moderation analysis with propensity score matching was used to adjust for potential confounding factors. The general and psychological health outcomes measured were past-month severe psychological distress, past-year suicidal ideation, participant's general health, and past-year health care avoidance due to possible mistreatment. GAMC during adolescence was negatively associated with severe psychological distress in adulthood. When examining past-year health care avoidance due to possible mistreatment, the effect sizes differed significantly between those in a trans-supportive state and those in a trans-unsupportive state. Our work highlights the importance of state-level policy stigma in understanding the association between GAMC and health outcomes. Findings point to the importance of enacting long-term legislative safeguards against TGD discrimination and removing barriers to access the full spectrum of care for adolescents who identify as TGD.
