Objective: Adolescence is a developmental period of increased risk for disordered eating. Gender minority adolescents (GMAs), or those whose gender identity does not align with their sex assigned at birth, may experience body image concerns related to unique gender-related stressors. GMAs may use disordered eating to affirm a feminine, masculine, or nonbinary gender identity. However, little is known about differences in disordered eating between GMAs and cisgender adolescents. Therefore, this study had two primary goals: (a) to compare disordered eating between GMAs and cisgender adolescents by examining the role of gender identity and sex assigned at birth; and (b) within GMAs, to examine associations between gender identity congruence and disordered eating.
Method: A large U.S. sample of GMAs and cisgender adolescents (n = 1,191 GMAs; 919 cisgender; Mage = 15.93 years) reported their disordered eating on an anonymous online survey.
Results: A MANOVA revealed a significant interaction between gender identity and sex assigned at birth. Follow-up ANOVAs demonstrated that purging, caloric restriction, excessive exercise, and muscle building differed as a function of gender identity and sex assigned at birth. Among GMAs, a multiple multivariate regression model demonstrated that disordered eating was lower among participants who reported greater gender identity congruence.
Discussion: GMAs should not be considered a homogenous group, as differences in gender identity may lead to the internalization of different appearance ideals and disparate eating disorder symptomatology. Results suggest that clinicians working with GMAs consider the unique body image concerns that could accompany a specific gender identity.
