Abstract
Purpose: To describe the prevalence of eating disorder symptoms among adolescents seeking gender -af firming care. Methods: Cross-sectional study of 660 gender -diverse adolescents who completed the Branched Eating Disorder Test to measure anorexia and bulimia symptoms. Results: 23.9% (95% CI 20.7-27.4) reported both anorexia symptoms, namely overvaluation of weight and fear of (or recurrent interference with) weight gain. 0.9% (95% CI 0.3-2.0) reported all bulimia symptoms, namely overvaluation of weight, recurrent binge eating, and recurrent compensatory behaviors (e.g., weekly purging). For all symptoms, prevalence was higher among i) adolescents assigned female at birth compared to those assigned male at birth, and ii) adolescents who felt unsure about their gender identity compared to those who identi fied as trans or nonbinary. Discussion: Clinicians should monitor eating disorder symptoms among adolescents presenting for gender -af firming care, especially among those assigned female at birth or who are unsure about their gender identity.
