Abstract
OBJECTIVE: We estimated the prevalence of diagnosed eating disorders, overall and by select demographics, among commercially insured individuals identified as transgender in a national claims database. METHODS: From the 2018 IBM® MarketScan® Commercial Database, there were 10,415 people identifiable as transgender based on International Classification of Disease (ICD-10) codes and procedure codes, specific to gender-affirming care, from inpatient and outpatient claims. Eating disorders were identified from ICD-10 codes and included anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, avoidant restrictive feeding and intake disorder, and other specified feeding and eating disorders. We estimated the prevalence of specific eating disorders diagnoses by selecting patient characteristics. RESULTS: Of individuals receiving some form of gender-affirming care, 2.43% (95% confidence interval: 2.14%-2.74%) were diagnosed with an eating disorder: 0.84% anorexia nervosa, 0.36% bulimia nervosa, 0.36% binge eating disorder, 0.15% avoidant restrictive feeding and intake disorder, 0.41% other specified feeding and eating disorders, and 1.37% with an unspecified eating disorder. Among transgender-identifiable patients aged 12-15 years, 5.60% had an eating disorder diagnosis, whereas 0.52% had an eating disorder diagnosis in patients aged 45-64 years. DISCUSSION: In patients identifiable as transgender, with receipt of gender-affirming care, the prevalence of diagnosed eating disorders was low compared to extant self-reported data for eating disorder diagnosis in transgender individuals. Among this population, eating disorders were highest in adolescents and young adults. Clinically verified prevalence estimates for eating disorder diagnosis in transgender people with a history of gender-affirming care warrant further investigation. PUBLIC SIGNIFICANCE: The present study aims to provide clinically validated, contemporary prevalence estimates for diagnosed eating disorders among a medically affirmed population of transgender adults and children in the United States. We report low prevalence of having any eating disorder relative to prevalence estimates reported in prior literature without clinical validation. These findings may be explained by access to affirming care and medical care generally.
