RESUMEN
BACKGROUND: Transgender and nonbinary (TGNB) adolescents and young adults are underrepresented in the literature on eating disorders and body image-related problems, despite increased mental health disparities and emerging research showing high associations between gender dysphoria, body image, and eating disorders among TGNB youth. AIMS: The scoping review was designed to critically examine the research on TGNB adolescents and young adults who experience eating and body image related problems as well as clinical studies on treatment approaches and effectiveness. METHOD: Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was used for reporting this scoping review. The electronic databases of MEDLINE and PsychInfo were used for searching subject terms. Inclusion criteria for studies required the quantitative measurement or qualitative exploration of body image or eating for transgender minor children, adolescents, or young adult samples (18 to 25 years old) and address differences in eating/body-related problems by age. The relevant data was extracted and narratively summarized. RESULTS: 49 studies were identified, data extracted, and analyzed. Increased prevalence of eating disorders and body image problems were identified for TGNB youth. Body-gender congruence through gender affirming social and medical interventions (e.g., hormone therapy) were noted as significant for alleviating body image problems and facilitating eating disorder treatment. Family and social factors were not well understood in the literature and a need for increased study of TGNB youth from varied racial/ethnic, neurodiverse, and within specific identities (e.g., nonbinary) and families and cultural contexts is still needed. CONCLUSIONS: Future research should consider the use of developmental and family theories for guiding inclusion of salient social factors influencing eating patterns, body image, and treatment outcomes. In addition, more studies are needed with those from minoritized racial and ethnic groups, neurodiversity, and varied gender identities (e.g., nonbinary and gender queer) for identifying important differences.
RESUMEN
BACKGROUND: Eating disorder treatment approaches and outcome studies have historically centered almost exclusively on cisgender populations. Transgender and nonbinary (TGNB) adults are underrepresented in general and intervention research despite being at increased risk for eating and body image-related problems. AIMS: This scoping review was designed to gather and examine the research with TGNB adults who experience eating and body image related problems, as well as clinical studies on the effectiveness of treatment approaches. METHOD: Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was used for reporting this review. MEDLINE and PsychInfo were used as electronic databases for searching subject terms. Inclusion criteria for studies required the quantitative measurement or qualitative exploration of body image or eating for TGNB adults. The relevant data were extracted and summarized based on quantitative findings and qualitative themes. RESULTS: After review of over 1258 articles, 59 studies met criteria and data were extracted and summarized. Factors associated with eating disorders and body image problems across studies suggests gender-affirming medical interventions are effective and emphasized treatment for an eating disorder is warranted alongside gender affirming medical care. Body image was associated with eating patterns aimed at meeting gendered ideals of body shape and size. There was variation in guiding theories and absence of consensus in the definition of transgender in the review studies. This likely demonstrates the changing language, social acceptance of TGNB people and identities, diagnostic criteria, and clinical conceptualizations of eating and body image. CONCLUSIONS: Future research should consider the use of theory for guiding inclusion of salient social factors influencing eating patterns, body image, and treatment outcomes. In addition, future research is needed that centers on nonbinary and genderqueer populations, as well as those from minoritized racial and ethnic groups to inform culturally appropriate concerns, needs, and treatment modalities.
Fifty-nine published research studies with transgender adults on eating patterns, body image, and associated risks and comorbidities were collected and summarized. Across studies, gender affirming medical interventions like hormone therapy and surgery were associated with decreases in eating disorder symptoms and improved body image. Studies from interviews with transgender adults found social causes for disordered eating and poor body image including rejection and discrimination. Future studies should use guiding theories for testing the causality and consider rejection and discrimination experienced by transgender adults.
