Predictors of eating-related psychopathology in transgender and gender nonbinary individuals

"That's not at all what I needed" trans adults' perspectives on trans-affirming primary care and eating disorders

Transgender and gender diverse adults, referred to collectively as trans, experience eating disorders (EDs) at high rates and struggle to find primary care providers (PCPs) knowledgeable in both gender-affirming care and EDs. Most research regarding healthcare experiences of trans people with EDs focuses on specialized treatment. This qualitative study explored the experiences of trans patients with ED symptoms in trans-affirming primary care, which offers clinical support for gender affirmation in the context of interpersonally gender-affirming primary care services. Twenty-two participants were recruited via social media to participate in focus groups (n = 5). Researchers utilized thematic analysis. Participants reported gender-affirming and non-affirming experiences, experienced unwelcome comments from providers regarding bodies and gender, encountered barriers to disclosing their ED symptoms, felt transition-related medical care supported recovery but did not always resolve their ED symptoms, felt they had to self-advocate, and wanted their providers to recognize them as whole people (beyond their ED and transness) who experience joy. Importantly, despite being trans-affirming, participants critiqued trans-affirming primary care as perpetuating weight stigma and binary gender norms. Participants recommended providers receive ED training, implement universal ED screening, and explore how sociocultural norms regarding weight and gender negatively impact trans health outcomes.

Eating disorder symptoms among transgender and gender diverse youth

Compared to cisgender peers, transgender and gender diverse (TGD) youth and adults report elevated eating disorder (ED) symptoms likely related to gender dysphoria and attempts to modify their bodies accordingly. Less is known about the impact on gender-affirming care and ED symptoms. This study aimed to expand on extant research and describe ED symptoms in TGD youth seeking gender-affirming care while exploring potential associations between gender-affirming hormone use and ED symptoms. A total of 251 TGD youth completed the Eating Disorders Examination-Questionnaire (EDE-Q) as part of routine clinical care. ANCOVAs and negative binomial regressions examined differences in ED symptoms among transgender females (identifying as female but assigned male at birth) and transgender males (identifying as male but assigned female at birth). ED severity was not significantly different among transgender females versus transgender males, (p = .09), or associated with gender-affirming hormone use (p = .07). Transgender females receiving gender-affirming hormones reported a greater proportion of objective binge eating episodes compared to those who were not (p = .03). Over a quarter of TGD youth reported engagement in ED behaviors suggesting assessment and intervention related to ED behaviors among TGD youth is imperative since adolescence is a particularly vulnerable period for adolescents and engagement in ED behaviors could lead to full ED development and medical risk.

A scoping review of the research literature on eating and body image for transgender and nonbinary adults

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.

Eating disorder symptomatology among transgender individuals: a systematic review and meta-analysis

OBJECTIVE

The purpose of this systematic review and meta-analysis was to synthesize the literature on eating disorders and eating disorder symptomatology among transgender individuals and to summarize the existing literature on gender-affirming treatment and the prevalence of eating disorder symptomatology.

METHOD

The literature search for this systematic review and meta-analysis was performed in PubMed, Embase.com, and Ovid APA PsycInfo. We searched for "eating disorders" and "transgender" using both controlled vocabularies and natural language terms for their synonyms. The PRISMA statement guidelines were followed. Quantitative data from studies on transgender individuals and eating disorders assessed with relevant assessment tools was included.

RESULTS

Twenty-four studies were included for the qualitative synthesis, and 14 studies were included in the meta-analysis. The results revealed higher levels of eating disorder symptomatology among transgender individuals compared with cisgender individuals, especially cisgender men. Transgender men tend to display higher levels of eating disorder symptomatology than transgender women; however, transgender women seem to have higher levels of eating disorder symptomatology than cisgender men and, interestingly, this study also noted a trend toward transgender men having higher levels of eating disorders than cisgender women. Gender-affirming treatment seems to alleviate the presence of eating disorder symptomatology in transgender individuals.

DISCUSSION

The body of research on this subject is extremely limited, and transgender individuals are underrepresented in the eating disorder literature. More research investigating eating disorders and eating disorder symptomatology in transgender individuals and the relationship between gender-affirming treatment and eating disorder symptomatology is needed.

Inaccessibility of care and inequitable conceptions of suffering: a collective response to the construction of "terminal" anorexia nervosa

Informed by our lived experiences with eating disorders, our work providing direct support to communities underserved by existing healthcare structures, and our commitment to social justice, we are deeply troubled by several aspects of the proposed characteristics for "terminal" anorexia nervosa outlined by Gaudiani et al. in Journal of Eating Disorders (10:23, 2022). We have identified two substantial areas of concern in the proposed characteristics provided by Gaudiani et al. and the subsequent publication by Yager et al. (10:123, 2022). First, the original article and the subsequent publication fail to adequately address the widespread inaccessibility of eating disorder treatment, the lack of parameters for what constitutes "high quality care", and the prevalence of trauma experienced in treatment settings for those who do access treatment. Second, the characteristics proposed for "terminal" anorexia nervosa are constructed largely based on subjective and inconsistent valuations of suffering which build on and contribute to harmful and inaccurate eating disorder stereotypes. Overall, we believe these proposed characteristics in their current form stand to detract from, rather than assist, the ability of patients and providers to make informed, compassionate, and patient-centered decisions about safety and autonomy both for individuals with enduring eating disorders and for individuals with more recently diagnosed eating disorders.

Transgender congruence, body appreciation, body dissatisfaction, and disordered eating in Chinese transgender adults

OBJECTIVE

Ample evidence shows that transgender congruence is negatively associated with body dissatisfaction and disordered eating in the Western context; however, limited research has explored these relationships in non-Western populations (e.g., Chinese transgender adults). Moreover, to our knowledge, there has been no research describing disordered eating in Chinese transgender adults. Thus, this study aimed to explore group differences in and relationships between transgender congruence, body appreciation, body dissatisfaction, and disordered eating in Chinese transgender adults.

METHODS

This study examined transgender congruence, body appreciation, body dissatisfaction, and disordered eating in a sample of Chinese transgender adults (N = 200). Chi-square, F tests, and correlation analyses were conducted to examine group differences and relationships between study variables.

RESULTS

Of the transgender adults, 31.0% screened positive as probable eating disorder (ED) cases. There were no gender identity differences in the study variables. Transgender congruence was positively associated body appreciation (r = .40, p < .001) and negatively associated with body dissatisfaction (r = -.26, p < .001) and disordered eating (r = -.15, p = .031).

DISCUSSION

Chinese transgender adults may be at high risk of EDs. Transgender congruence and body appreciation may serve a protective role in the context of eating pathology in Chinese transgender adults. Future research is needed to validate the observed relationships between transgender congruence, body appreciation, body dissatisfaction, and disordered eating in Chinese transgender adults.

PUBLIC SIGNIFICANCE

Research on disordered eating and body image in Chinese transgender adults is limited. This study describes disordered eating and its relations with transgender congruence, body appreciation, and body dissatisfaction in Chinese transgender adults. Findings highlight the need for and implications of ED intervention in Chinese transgender adults.

Gender and sex in eating disorders: A narrative review of the current state of knowledge, research gaps, and recommendations

INTRODUCTION

Eating disorders (EDs) have long been considered conditions exclusively affecting women, and studies in the ED field regularly exclude men. Research efforts are needed to better understand the role of gender and sex in EDs. This review describes the role of gender and sex in the development of EDs from a biopsychosocial perspective.

METHODS

The primary hypothesis of this narrative review is that gender and sex interact to influence ED risk. The literature review was conducted using the PubMed database.

RESULTS

This review first presents the general characteristics and prevalence of EDs according to gender and sex. Next, neurodevelopmental processes, neurobiology, gender roles, body image, and the minority stress model are addressed. Lastly, research perspectives to better include gender and sex in the field of EDs are discussed (e.g., representation of gender and sex diversities, development of appropriate assessment tools, and increasing awareness).

CONCLUSION

Although substantial knowledge gaps remain, there is a growing recognition of the importance of integrating gender and sex in ED research that holds promise for further development in the field.

Risk factors for eating disorders: findings from a rapid review

BACKGROUND

Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid Review aimed to identify and summarise research studies conducted within the last 12 years, focusing on risk factors associated with eating disorders.

METHODS

The current review forms part of a series of Rapid Reviews to be published in a special issue in the Journal of Eating Disorders, funded by the Australian Government to inform the development of the National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2021, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, or population studies). Data pertaining to risk factors for eating disorders were synthesised and outlined in the current paper.

RESULTS

A total of 284 studies were included. The findings were divided into nine main categories: (1) genetics, (2) gastrointestinal microbiota and autoimmune reactions, (3) childhood and early adolescent exposures, (4) personality traits and comorbid mental health conditions, (5) gender, (6) socio-economic status, (7) ethnic minority, (8) body image and social influence, and (9) elite sports. A substantial amount of research exists supporting the role of inherited genetic risk in the development of eating disorders, with biological risk factors, such as the role of gut microbiota in dysregulation of appetite, an area of emerging evidence. Abuse, trauma and childhood obesity are strongly linked to eating disorders, however less conclusive evidence exists regarding developmental factors such as role of in-utero exposure to hormones. Comorbidities between eating disorders and mental health disorders, including personality and mood disorders, have been found to increase the severity of eating disorder symptomatology. Higher education attainment, body image-related factors, and use of appearance-focused social media are also associated with increased risk of eating disorder symptoms.

CONCLUSION

Eating disorders are associated with multiple risk factors. An extensive amount of research has been conducted in the field; however, further studies are required to assess the causal nature of the risk factors identified in the current review. This will assist in understanding the sequelae of eating disorder development and in turn allow for enhancement of existing interventions and ultimately improved outcomes for individuals.

Social and contextual influences on eating pathology in transgender and nonbinary adults

Eating pathology (EP) is reported at alarmingly high rates among transgender and nonbinary (TNB) people. The present study investigates key associations between experiences that are common in TNB populations and EP. TNB individuals located within the United States (N = 212) who self-identified as currently experiencing disordered eating or an eating disorder were recruited from social media outlets and completed an online survey that included measures of EP, discrimination-based trauma symptoms, internalized transphobia, and gender dysphoria. The average age of participants was just over 27 years old (SD = 6.22) and the majority of participants (68.9%) were nonbinary. Data were analyzed using IBM SPSS version 28 and PROCESS 4.0. Discrimination trauma [β = .27, t(211) = 3.90, p < .001] and internalized transphobia [β = .21, t(211) = 3.03, p = .003] were significant predictors of EP in a multiple regression model. Additionally, internalized transphobia partially mediated the association between discrimination trauma and EP. Findings reinforce the need for trauma-informed and multiculturally competent provision of services for TNB populations presenting with eating concerns. Results also highlight the complex role that previously unexplored variables play in the etiology of EP for TNB populations. Implications and clinical recommendations are discussed.

Factors that drive mental health disparities and promote well-being in transgender and nonbinary people

Transgender (or trans) is an umbrella term for individuals who experience their gender differently from what is associated with the sex they were assigned at birth. Individuals who are nonbinary experience their gender outside binary conceptions of gender. Although research has predominantly focused on negative mental health outcomes for transgender and non-binary (TNB) individuals, an emergent literature has begun to explore protective and health-promoting factors and dimensions of psychological well-being. In this Review, we discuss the sociocultural context for TNB people, beginning with a brief history of TNB identity before highlighting frameworks for understanding the higher prevalence of certain mental health concerns among TNB individuals. Next, we summarize the predictive factors associated with higher rates of depression, anxiety, suicidality, trauma-related concerns, disordered eating behaviours and substance use. We also review TNB coping, resilience and resistance to anti-trans stigma, as well as psychological well-being, flourishing and gender euphoria. Tying these topics together, we discuss affirming interventions for reducing mental health disparities and promoting psychological health in TNB individuals and communities. We conclude by discussing future research directions.

Individuals who are transgender or nonbinary experience a higher prevalence of certain mental health concerns, including depression, anxiety and disordered eating behaviours. In this Review, Tebbe and Budge discuss these disparities along with factors that protect these individuals from negative outcomes and promote well-being.

Presentation of Patients with Eating Disorders to a Pediatric Quaternary-Level Care Emergency Department During the COVID-19 Pandemic

Despite an overall decrease in utilization of emergency departments during COVID-19 (Hartnett et al. in MMWR Morb Mortal Wkly Rep. 69(23):699-704, 2020), US pediatric emergency departments experienced an increase in mental health visits for children and adolescents (Leeb et al. in MMWR Morb Mortal Wkly Rep. 69(45):1675-80, 2020). Simultaneously, individuals with eating disorders reported increasing symptomology (Termorshuizen et al. in Int J Eat Disord. 53(11):1780-90, 2020). This study compares Emergency Department utilization at a pediatric quaternary-level care center by patients with eating disorders during the pandemic (March-Dec 2020) vs March-Dec 2019. We hypothesize that there was an increase in presentation of patients with eating disorders. An Informatics for Integrating Biology and the Bedside query of the electronic medical record system identified patients with eating disorder diagnoses per ICD9/ICD10 codes aged 6-23 who presented to the Emergency Department between March 1^st and December 31^st of 2020 and 2019. Subsequent retrospective chart review was carried out. Patients were excluded from analysis if the presenting problem was not directly related to the eating disorder. During March-Dec 2019, 0.581% percent of all patients presented to the Emergency Department due to an eating disorder. During the same time frame in 2020, however, that percentage increased to 1.265%. Statistical significance was corrected using a Benjamini-Hochberg analysis. Despite a 66.5% decline in overall visits to the Emergency Department, the percentage of patients presenting with eating disorders doubled during the pandemic. During the pandemic, the total time spent awaiting placement significantly increased, and the number of patients identifying as transgender and/or nonbinary increased. Our data support the hypothesis that eating disorder presentation increased during the pandemic.

Sexual and gender minority (SGM) adolescents' disordered eating: Exploring general and SGM-specific factors

OBJECTIVE

Sexual and gender minority (SGM) adolescents disproportionately report disordered eating, yet have primarily been considered under a larger SGM umbrella. The current study 1) compared disordered eating between sexual minority (SM) and gender minority (GM) adolescents; 2) examined how general psychological factors (self-esteem, depression, and stress) and SGM-specific factors (e.g., feelings about SGM identity, access to SGM resources) were associated with disordered eating; and 3) examined whether associations between these factors differed for SM versus GM adolescents.

METHOD

SGM adolescents in the U.S. (N = 8814; 35.0% GM; 43.7% cisgender girls; 66.9% White; M_age  = 15.6) reported their disordered eating, depressive symptoms, stress, self-esteem, and SGM-related experiences on an anonymous, cross-sectional online survey.

RESULTS

GM adolescents exhibited a higher prevalence of clinical threshold disordered eating than SM adolescents. Self-esteem was associated with lower odds of caloric restriction, purging, and binge eating. Depression was associated with higher odds of caloric restriction, diet pill use, purging, laxatives, and binge eating. Stress was associated with higher odds of purging. Associations were stronger for GM adolescents' caloric restriction. Positive feelings about SGM identity were associated with lower odds of caloric restriction, purging, and binge eating, whereas greater stress of "coming out" was associated with higher odds of caloric restriction, purging, and binge eating.

DISCUSSION

These results suggest that SGM adolescents' disordered eating is associated with both general psychological factors and unique SGM experiences. Results highlight the importance of considering how the unique experiences of SGM youth may leave them vulnerable to disordered eating behaviors.

PUBLIC SIGNIFICANCE STATEMENT

Sexual and gender minority (SGM) youth are disproportionately affected by disordered eating. The current study found that higher depression and stress, and lower self-esteem, were associated with SGM adolescents' disordered eating. Furthermore, unique SGM experiences, such as stress about coming out, were also associated with eating pathology. Results highlight the importance of considering SGM adolescents' perceptions of their identity and social support.

Prevalence of diagnosed eating disorders in US transgender adults and youth in insurance claims

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.

Appearance and performance-enhancing drugs and supplements, eating disorders, and muscle dysmorphia among gender minority people

OBJECTIVE

Appearance and performance-enhancing drugs and supplements (APEDS) can be used to enhance muscle growth, athletic performance, and physical appearance. The aim of this study was to examine the lifetime use of APEDS and associations with eating disorder and muscle dysmorphia symptoms among gender minority people.

METHOD

Participants were 1653 gender minority individuals (1120 gender-expansive [defined as a broad range of gender identities that are generally situated outside of the woman-man gender binary, e.g., genderqueer, nonbinary] people, 352 transgender men, and 181 transgender women) recruited from The Population Research in Identity and Disparities for Equality Study in 2018. Regression analyses stratified by gender identity examined associations of any APEDS use with eating disorder and muscle dysmorphia symptom scores.

RESULTS

Lifetime APEDS use was common across groups (30.7% of gender-expansive people, 45.2% of transgender men, and 14.9% of transgender women). Protein supplements and creatine supplements were the most commonly used APEDS. Among gender-expansive people and transgender men, lifetime use of any APEDS was significantly associated with higher eating disorder scores, dietary restraint, binge eating, compelled/driven exercise, and muscle dysmorphia symptoms. Any APEDS use was additionally associated with laxative use among gender-expansive people. Among transgender women, use of any APEDS was not significantly associated with eating disorder or muscle dysmorphia symptoms.

DISCUSSION

APEDS use is common and associated with eating disorder and muscle dysmorphia symptoms in gender-expansive people and transgender men, thus highlighting the importance of assessing for these behaviors and symptoms among these populations, particularly in clinical settings.

PUBLIC SIGNIFICANCE

This study aimed to examine APEDS use among gender minority people. We found that 30.7% of gender-expansive (e.g., nonbinary) people, 45.2% of transgender men, and 14.9% of transgender women reported lifetime APEDS use, which was associated with eating disorder and muscle dysmorphia symptoms in transgender men and gender-expansive people. Clinicians should assess for these behaviors in gender minority populations.

Mental health in transgender individuals: a systematic review

Several lines of evidence indicate the prevalence of mental health disorders in Transgender (TG) individuals is higher than that of cisgender individuals or the general population. In this systematic review, we aim to propose a summary of some of the most significant research investigating mental health disorders' prevalence among this population. We performed a double-blind systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting (PRISMA) on PUBMED/MEDLINE and SCOPUS, specifically using peer-reviewed articles examining the mental health status of transgender (TG) individuals. This review did not exclude any research based on publication date. The last search was performed in February 2022. The employed search strategy led to the selection of 165 peer-reviewed articles. The majority of these papers presented a cross-sectional design with self-reported diagnoses and symptoms, signaling a significant prevalence of mental health disorders amongst TG Individuals. Of the reviewed articles, 72 examined the prevalence of mood and anxiety disorders; 8 examined eating disorders; 43 examined the prevalence of suicidal or self-harm ideation or behaviors; 5 papers examined the prevalence of trauma and stress-related disorders; 10 examined the frequency of personality disorders; 44 examined substance use disorders; and 9 papers examined the prevalence of autism spectrum disorder. Finally, 22 studies reported on the prevalence of TG individuals diagnosed with co-morbid mental health disorders or unspecified mental disorders. Our findings coincide with existing research, which indicates TG individuals do experience a higher prevalence of mental health disorders than that of the general population or cisgender individuals. However, further research is needed to address the existing gaps in knowledge.

Validation and measurement invariance of the muscularity-oriented eating test among Brazilian men and women

OBJECTIVE

The Muscularity-Oriented Eating Test (MOET) is a 15-item unidimensional scale, designed to assess eating practices that occur in the pursuit of a muscular body. The aim of the present study was to describe the translation and cultural adaptation of the MOET to Brazilian Portuguese, to explore its factor structure and measurement invariance, and to evaluate its internal consistency, three-week test-retest reliability, and convergent validity in a community sample of Brazilian men and women.

METHOD

After the back-translation procedure, the Brazilian MOET was administered online to a sample of 1246 adults (634 men and 612 women), along with measures of drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating behaviors, and exercise dependence.

RESULTS

Findings from an exploratory factor analysis and a confirmatory factor analysis revealed a one-factor structure and adequate internal consistency for men (ω = 0.86; α = 0.86) and women (ω = .84; α = .83). Measurement invariance across gender was supported. In addition, the scale demonstrated good three week test-retest reliability for both men (ICC = .96; p < .001) and women (ICC = .92; p < .001), and the subscales revealed moderate to large associations with drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating, and exercise dependence.

CONCLUSION

This study supports the validity and reliability of the MOET in a community sample of Brazilian men and women and represents an advance in measures of muscularity-oriented disordered eating in Brazilian adults, allowing for future cross-cultural studies in this field.

PUBLIC SIGNIFICANCE

The Muscularity-Oriented Eating Test (MOET) is a measure of muscularity-oriented disordered eating, which assess strict adherence to diet rules, including the food's macronutrient content, regulation of protein intake, and eating less or more to influence muscle gain. This study evaluated the validity and reliability of the MOET in a community sample of Brazilian men and women. Our findings represent an advance in measures of muscularity-oriented disordered eating in Brazilian adults.
