Desire for Gender-Affirming Medical Care Before Age 18 in Transgender and Nonbinary Young Adults.

Purpose: We aimed to understand transgender and nonbinary (TNB) young adults' desire to receive gender-affirming medical care (GAMC) before age 18 and identify barriers and facilitators to receiving this care in adolescence. Methods: A cross-sectional survey was administered to TNB young adults presenting for care between ages 18 and 20 in 2023. Descriptive statistics characterized the sample, χ² tests with post hoc pairwise comparisons identified differences in desire for gender-affirming medications, outness, and parental consent by gender identity and sex assigned at birth, and t-tests evaluated differences in barriers and facilitators to receiving care by outness to parents. Results: A total of 230 TNB respondents had complete data. Nearly all (94.3%) indicated they desired GAMC before age 18. Half (55.7%) of the respondents reported being out about their gender identity to a parent before age 18. Outness, discussing desire for GAMC, and asking for consent to receive GAMC from a parent were significantly more common among participants who identified as men compared to those who identified as women and among those assigned female at birth compared to those assigned male at birth. No such differences emerged when comparing nonbinary individuals to those who identified as men or women. Lack of parental willingness to consent for GAMC was cited as the primary contributor of not having received care in adolescence. Conclusions: Many TNB young adults desire GAMC in adolescence; however, lack of parental support is a key barrier to receiving this care, suggesting a need for more readily available resources for parents to support TNB adolescents.
