Factors Associated with Time to Receiving Gender-Affirming Hormones and Puberty Blockers at a Pediatric Clinic Serving Transgender and Nonbinary Youth.

Purpose: To describe barriers to care for a cohort of transgender and nonbinary (TNB) youth and examine factors associated with delays in receiving puberty blockers (PBs) or gender-affirming hormones (GAHs). Methods: We used longitudinal data from a prospective cohort of TNB youth seeking care at a multidisciplinary pediatric gender clinic between August 2017 and June 2018. We calculated the time between (i) initial clinic contact, (ii) phone intake, (iii) first medical appointment, and (iv) initiating PBs/GAHs. We estimated Kaplan-Meier curves for each time-to-care interval and used Cox regression models to estimate hazard ratios (HRs) for factors hypothesized to be barriers and facilitators of care. Results: Our cohort included 104 youth aged 13-20 years. The median time from contacting the clinic to initiating PBs/GAHs was 307 days (range, 54-807). Lower income level, Medicaid insurance, and lack of family support were associated with longer times from contacting the clinic to completing the first medical appointment. In addition, older youth experienced longer times to first medical appointment relative to youth aged 13-14 years. Youth younger than 18 years of age who did not complete a mental health assessment before their first medical appointment experienced delays from first medical appointment to initiating PBs/GAHs (HR=0.44, 95% confidence interval, 0.22-0.88). Conclusion: Certain subsets of youth disproportionately experienced delays in receiving gender-affirming medications, and these factors varied by stage of care engagement. Given the association between gender-affirming care and improved mental health, identifying sociostructural and clinic-level barriers to care is critically important to facilitating more equitable access.
