Understanding the Complex Relationship Between One's Body, Eating, Exercise, and Gender-Affirming Medical Care Among Transgender and Nonbinary Adolescents and Young Adults.

Purpose: Gender dysphoria has been linked to body dissatisfaction, which can affect an individual's eating and exercise habits and increase their risk for disordered eating. The prevalence of eating disorders among transgender and nonbinary (TGNB) adolescents and young adults (AYA) ranges from 5% to 18% and studies have found a higher risk of disordered eating among these AYA in comparison to their cisgender peers. However, there is minimal research on why TGNB AYA are at higher risk. The aim of this study is to understand unique factors that define a TGNB AYA's relationship between their body and food, how this relationship may be affected by gender-affirming medical care, and how these relationships may contribute to disordered eating.

Methods: A total of 23 TGNB AYA were recruited from a multidisciplinary gender-affirming clinic to participate in semistructured interviews. Transcripts were analyzed using Braun and Clarke's theory of thematic analysis (2006).

Results: The average age of participants was 16.9 years. Forty-four percent of participants identified as having a transfeminine gender identity, 39% transmasculine, and 17% nonbinary/gender fluid. Five themes emerged regarding TGNB participants' relationship to food and exercise: gender dysphoria and control over one's body, societal expectations of gender, mental health and safety concerns, emotional and physical changes with gender-affirming medical care, and recommended resources for TGNB AYA.

Conclusion: By understanding these unique factors, clinicians can provide targeted and sensitive care when screening and managing disordered eating among TGNB AYA.
