Transgender and other gender diverse adolescents with eating disorders requiring medical stabilization

J Eat Disord. 2022 Dec 23;10(1):199. doi: 10.1186/s40337-022-00722-7.

Abstract

Background: Despite the high prevalence of eating disorders in gender diverse adolescents, little is known about the characteristics of gender diverse youth with eating disorders who require inpatient medical stabilization. The primary objective of this study was to describe the medical, anthropometric, and psychiatric characteristics of gender diverse adolescents hospitalized for eating disorders and compare these characteristics to cisgender peers hospitalized for eating disorders. The secondary objective was to evaluate percent median body mass index as one marker of malnutrition and treatment goal body mass index as a recovery metric between patients' birth-assigned sex and affirmed gender using standardized clinical growth charts.

Methods: A retrospective chart review was conducted of 463 patients admitted to an inpatient eating disorders medical unit between 2012 and 2020. To compare medical, anthropometric, and psychiatric data between gender diverse and cisgender patients, chi-square/Fisher's exact and t-tests were used. Clinical growth charts matching the patients' birth-assigned sex and affirmed gender identity were used to assess percent of median body mass index and treatment goal body mass index.

Results: Ten patients (2.2%) identified as gender diverse and were younger than cisgender patients [13.6 (1.5) years vs. 15.6 (2.7) years, p = 0.017]. Gender diverse patients were hospitalized with a higher percent median body mass index compared to cisgender peers [97.1% (14.8) vs. 87.9% (13.7), p = 0.037], yet demonstrated equally severe vital sign instability such as bradycardia [44 (8.8) beats per minute vs. 46 (10.6) beats per minute, p = 0.501], systolic hypotension [84 (7.1) mmHg vs. 84 (9.7) mmHg, p = 0.995], and diastolic hypotension [46 (5.8) mmHg vs. 45 (7.3) mmHg, p = 0.884]. Gender diverse patients had a higher prevalence of reported anxiety symptoms compared to cisgender patients (60% vs. 28%, p = 0.037).

Conclusions: Gender diverse patients demonstrated complications of malnutrition including vital sign instability despite presenting with a higher weight. This is consistent with a greater proportion of gender diverse patients diagnosed with atypical anorexia nervosa compared to cisgender peers. Additionally, psychiatric comorbidities were present among both groups, with a larger percentage of gender diverse patients endorsing anxiety compared to cisgender patients.

Plain language summary

Gender diverse is a term that includes gender identities such as (but not limited to) transgender, non-binary, and gender fluid. Eating disorders are becoming increasingly recognized among this population. In recent years there has been a better understanding of the risk factors and screening for eating disorders in the outpatient setting for gender diverse adolescents. However, the medical, anthropometric, and psychiatric characteristics of gender diverse adolescents with eating disorders requiring inpatient medical stabilization are poorly understood. This study examines these characteristics in gender diverse adolescents hospitalized for eating disorder-related medical complications from 2012 to 2020. Gender diverse adolescents presented for medical hospitalization with signs of malnutrition, including vital sign instability and laboratory abnormalities, as well as additional psychiatric diagnoses such as depression and anxiety. Understanding the medical, anthropometric, and psychiatric presentation of this population can lead to more tailored and comprehensive care with the potential to reduce the risks of adverse health outcomes.
