The enigma of male eating disorders: A critical review and synthesis

Eating-related pathology at the intersection of gender identity and expression, sexual orientation, and weight status: An intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) of the Growing Up Today Study cohorts

The objective of this study was to investigate how gender identity, the overwhelmingly prioritized dimension of social identity/position in eating-related pathology research, intersects with gender expression, sexual orientation, and weight status to structure the social patterning of eating disorders and disordered eating behaviors among young people in the U.S. Data were drawn from the 2010/2011 Growing Up Today Study (GUTS; N = 11,090-13,307). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) by nesting participants within social strata defined by intersecting gender identity, gender expression, sexual orientation, and weight status categories in a series of multilevel logistic models for four outcomes (past-year purging, overeating, and binge eating; lifetime eating disorder diagnosis). To illustrate the advantages of intersectional MAIHDA, we compared the results to those from unitary and conventional intersectional analyses. The intersectional MAIHDA revealed a complex social patterning of eating-related pathology characterized by heterogeneity and outcome-specificity. Several multiply marginalized strata (e.g., those including gender nonconforming, sexual minority, and/or larger-bodied girls/women) had disproportionately elevated prevalence, although all estimates were driven by additive effects. Notably, these patterns were obscured within the unitary and conventional intersectional analyses. Future epidemiologic research on eating-related pathology should continue to adopt an intersectional approach through the use of appropriate methodologies.

Community norms of the Muscle Dysmorphic Disorder Inventory (MDDI) among cisgender sexual minority men and women

BACKGROUND

Representing the pathological extreme pursuit of muscularity, muscle dysmorphia (MD) is characterized by a pervasive belief or fear around insufficient muscularity and an elevated drive for muscularity. Despite evidence of elevated body image-related concerns among sexual minority populations, little is known about the degree of muscle dysmorphia (MD) symptoms among sexual minorities, particularly based on Muscle Dysmorphic Disorder Inventory (MDDI) scores. The objective of this study was to examine the nature and severity of MD symptoms in cisgender sexual minority men and women and provide community norms of the MDDI for these populations.

METHODS

Data from participants in The PRIDE Study, an existing study of health outcomes in sexual and gender minority people from the United States, were examined. Participants included cisgender gay men (N = 1090), cisgender bisexual plus (bisexual, pansexual, and/or polysexual) men (N = 100), cisgender lesbian women (N = 563), and cisgender bisexual plus women (N = 507). We calculated means, standard deviations (SD), and percentiles for the MDDI total and subscale scores for cisgender sexual minority men and women. We compared MDDI scores by sexual orientation using linear regression models, both unadjusted and adjusted for sociodemographics.

RESULTS

Overall, the sample was 85.2% White, 3.0% Asian or Pacific Islander, 2.0% Black, 0.5% Native American, 3.9% multiracial, and 6.6% Hispanic/Latino/a. The mean age was 38.6 (SD = 14.3) and 69.4% had a college degree or higher. Means (SD) for the MDDI total score were 27.4 (7.7) for cisgender gay men, 26.4 (6.4) for cisgender bisexual plus men, 24.3 (6.1) for cisgender lesbian women, and 24.6 (5.5) for cisgender bisexual plus women. There were no significant differences in MDDI scores between cisgender gay and bisexual plus men, or between cisgender lesbian women and bisexual plus women in unadjusted or adjusted models.

CONCLUSIONS

These normative data provide insights into the experience of MD symptoms among cisgender sexual minority men and women and can aid researchers and clinicians in the evaluation of MD symptoms and interpretation of MDDI scores in sexual minority populations.

Seeing yourself clearly: Self-identification of a body image problem in adolescents with an eating disorder

AIM

Many adolescents who meet diagnostic criteria for an eating disorder do not self-identify as having a problem and may consequently be less likely to seek help. Extant research investigating self-identification has been limited to specific populations (ie, girls meeting criteria for bulimic-type eating disorders). This study investigated how self-identification varied across sex, eating disorder diagnoses, and the presence of extreme eating behaviours, and how self-identification was related to help-seeking in adolescents.

METHODS

Participants included 1002 Australian school students (75.5% female, M_age = 15.14 years, SD = 1.40) who met DSM-5 diagnostic criteria for an eating disorder. An online survey assessed self-identification of having a body image problem, as well as sex, eating disorder diagnosis, extreme eating behaviours, help-seeking for a body image problem, and other potential correlates of self-identification (demographics, psychological distress, social function, weight and shape concerns).

RESULTS

Approximately, 2 in 3 adolescents with an eating disorder self-identified as having a body image problem. Girls who met criteria for a major eating disorder diagnosis, and those engaging in extreme eating behaviours, were more likely to self-identify. When adjusting for covariates, only sex remained significantly associated with self-identification. Adolescents who self-identified were 2.71 times more likely to seek help for a body image problem, adjusting for covariates.

CONCLUSIONS

Public health strategies ought to promote awareness regarding the different ways that body image problems might manifest among both girls and boys, as well as the potential gravity of such problems. Awareness among parents, teachers and primary care providers should also be considered.

Examining associations among weight stigma, weight bias internalization, body dissatisfaction, and eating disorder symptoms: Does weight status matter?

The present study aimed to expand weight stigma theoretical models by accounting for central tenets of prominent eating disorder (ED) theories and increasing the generalizability of existing models for individuals across the weight spectrum. College students (Sample 1: N = 1228; Sample 2: N = 1368) completed online surveys assessing stigma and ED symptoms. In each sample, separately, multi-group path analyses tested whether body mass index (BMI) classification (underweight/average weight, overweight, obese) moderated a model wherein weight stigma experiences were sequentially associated with weight bias internalization, body dissatisfaction, and five ED symptoms: binge eating, purging, restricting, excessive exercise, muscle building behaviors. Results supported the assessed model overall and for individuals in each BMI class, separately. Although patterns of associations differed for individuals with different BMIs, these variations were limited. The present findings suggest that the adverse impact of weight stigma on distinct ED symptoms is not limited to individuals with elevated BMIs and that these associations are generally explained by the same mechanisms. Weight stigma interventions that focus on decreasing weight bias internalization and body dissatisfaction are recommended for individuals across the weight spectrum. Further examination of associations between weight stigma and multiple ED symptoms, beyond disinhibited eating, is supported.

Detection, treatment, and course of eating disorders in Finland: A population-based study of adolescent and young adult females and males

Objective:

We assessed the detection, treatment and outcomes of DSM-5 eating disorders in a nationwide community setting.

Method:

The FinnTwin12 cohort comprises twins born in 1983–1987 in Finland (n = 5,600), with follow-up starting at age 12. We outline treatment and outcomes of the 127 females and 15 males diagnosed with a lifetime DSM-5 eating disorder in interviews conducted for a subsample (n = 1,347) in their early 20s.

Results:

Only 45 (32%) of those diagnosed with eating disorder in the interviews had their condition detected in healthcare, and even fewer received treatment (30% of females, 13% of males). Anorexia nervosa (AN), bulimia nervosa, and atypical AN were detected and treated more often than other eating disorders. Five years after disease onset, 41% of those diagnosed had recovered. There were no statistically significant differences in the course of different eating disorders (log-rank p = 0.66) but the outcome was more favourable among males (log-rank p = 0.008). The likelihood of 5-year recovery did not differ between those who had and who had not received treatment (41.1% vs. 40.5%, log-rank p = 0.66).

Conclusion:

Although eating disorders are common and symptoms are persistent for many, they remain under-diagnosed and under-treated. In real-world settings, effectiveness of provided treatments may be limited.

Self-Perception and Self-Acceptance Are Related to Unhealthy Weight Control Behaviors in Catalan Adolescents: A Cross-Sectional Study

Adolescence is associated with a higher vulnerability that may result in a high dissatisfaction, the practice of unhealthy weight-control behaviors (UWCB) and, eventually, the onset of body image-related mental disorders. These factors are strongly associated with the social context, so it is important to characterize them in local or regional studies. To assess the relationship between body image and UWCB presence, a cross-sectional study was performed among 2496 schooled adolescents from Lleida (Spain) between 2017 and 2019. Their perceived and desired images were evaluated and compared with the real image in order to obtain the body distortion and the body dissatisfaction and relate them with UWCB. The studied individuals perceived themselves thinner than they actually were, with no differences between males and females. However, differences were found regarding body dissatisfaction, showing that females desired to be thinner, while males desired a more corpulent body image. Furthermore, one out of ten individuals reported UWCB, with higher prevalence among females. UWCB was associated with a desire to be thinner and with distorted body images. It is essential to work on self-perception and self-acceptance in early adolescence from an interdisciplinary perspective at educational, social and health levels to promote health in adolescence.

Addressing Disparities in Adolescent Eating Disorders: A Case Report of Family-Based Treatment in Primary Care

Eating disorders typically have a protracted course, marked by significant morbidity. Male adolescents and adolescents of color are at risk of delayed care. Primary care providers are well-positioned to identify eating disorders early and initiate treatment. This case report describes an adaptation of Family-Based Treatment delivered by a primary care provider to an Asian-American male adolescent from an immigrant family with restrictive anorexia nervosa. The adolescent achieved full-weight restoration and remission of his anorexia through treatment in primary care. Embedding eating disorder treatment within primary care could improve detection, engagement, and retention in treatment among young people from diverse backgrounds.

Emotional eating across different eating disorders and the role of body mass, restriction, and binge eating

OBJECTIVE

Different subtypes of eating disorders (ED) show dysfunctional eating behaviors such as overeating and/or restriction in response to emotions. Yet, systematic comparisons of all major EDs on emotional eating patterns are lacking. Furthermore, emotional eating correlates with body mass index (BMI), which also differs between EDs and thus confounds this comparison.

METHOD

Interview-diagnosed female ED patients (n = 204) with restrictive (AN-R) or binge-purge anorexia nervosa (AN-BP), bulimia nervosa (BN), or binge-eating disorder (BED) completed a questionnaire assessing "negative emotional eating" (sadness, anger, anxiety) and "happiness eating." ED groups were compared to BMI-matched healthy controls (HCs; n = 172 ranging from underweight to obesity) to exclude BMI as a confound.

RESULTS

Within HCs, higher BMI was associated with higher negative emotional eating and lower happiness eating. AN-R reported the lowest degree of negative emotional eating relative to other EDs and BMI-matched HCs, and the highest degree of happiness eating relative to other EDs. The BN and BED groups showed higher negative emotional eating compared to BMI-matched HCs. Patients with AN-BP occupied an intermediate position between AN-R and BN/BED and reported less happiness eating compared to BMI-matched HCs.

DISCUSSION

Negative emotional and happiness eating patterns differ across EDs. BMI-independent emotional eating patterns distinguish ED subgroups and might be related to the occurrence of binge eating versus restriction. Hence, different types of emotional eating can represent fruitful targets for tailored psychotherapeutic interventions. While BN and BED might be treated with similar approaches, AN-BP and AN-R would need specific treatment modules.

Intimate partner violence and muscularity-building behavior in latino sexual minority men

Intimate partner violence (IPV) has been associated with increased prevalence of eating disorders. In men, disordered eating is often related to the muscularized ideal. Sexual minority men (SMM; e.g., gay, bisexual, etc.) are at higher risk for eating disorders and Latino SMM may be at particularly high risk; however, IPV and eating pathology has yet to be examined in this population. Therefore, the aim of this study is to elucidate the association between IPV and muscularity-related dissatisfaction and muscularity-oriented behavior in Latino SMM. Participants were 81 Latino SMM. Thirty participants (37% of the sample) met the cutoff score for experiencing IPV in the past month. In bivariate analyses, IPV was associated with muscularity-oriented behavior, but not muscularity-related dissatisfaction. In multivariable analyses, IPV was negatively associated with muscularity-related dissatisfaction with a small effect size and positively associated with muscularity-oriented behavior with a large effect size. It may be that SMM engage in muscle building behavior to increase self-esteem, regulate affect, or better physically protect themselves from their abusive partner. Future research should investigate motivation for muscle building behavior in individuals experiencing IPV.

Sexual Practices and Satisfaction among Gay and Heterosexual Men in Romantic Relationships: A Comparison Using Coarsened Exact Matching in a U.S. National Sample

Gay men are underrepresented in research on sexual satisfaction. We examined sexual satisfaction and over 50 sexual practices in an online U.S. national survey of men in relationships. Coarsened exact matching created comparable samples of heterosexual (n = 3527) and gay (n = 452) men on six demographic factors, including relationship length. Results identified many similarities between the groups, including sexual frequency, orgasm frequency, duration of sex, and sexual satisfaction. The majority of heterosexual and gay men expressed physical or emotional affection during their last sexual encounter, reporting that they or their partner said "I love you" (66%; 57%) and engaged in deep kissing (69%; 75%) or gentle kissing (82%; 72%). Heterosexual men were less likely than gay men to usually-always receive (27%; 61%) or give (37%; 68%) oral sex when intimate in the past month; were less likely to view pornography with their partner (35%; 61%); but were more likely to give their partner massages in the past year to improve their sex lives (71%; 58%). Number of sexual communication behaviors was a strong predictor of sexual satisfaction, particularly for gay men (β =.36). These findings enhance our understanding of heterosexual and gay men's sexual lives.

Registered report: Initial development and validation of the eating disorders safety behavior scale

Anxiety and eating disorders (EDs) often co-occur, prompting calls to explore anxiety-related maintenance processes in ED samples. Safety behaviors, which function to prevent a feared outcome from occurring or to reduce anxiety associated with a feared stimulus, are observed across anxiety disorders and, along with overt avoidance behaviors, are an important target in treatment. Data suggest that individuals with EDs also engage in safety behaviors. However, no existing assessments provide a comprehensive measure of eating-disorder-specific overt avoidance and safety behaviors. The goal of this Stage 1 Registered Report is to develop a comprehensive self-report measure of ED-specific safety behaviors. In Study 1, we will recruit 50 women with EDs to complete the scale and provide feedback on the response scale. Feedback from these participants will be used to refine the measure. In Study 2, we will evaluate the psychometric properties of the measure in a large sample of women with EDs (n dependent on the size of measurement) and a community sample without current or a history of ED symptoms. We will explore the measure factor structure, known-groups validity by comparing scores from women with EDs to healthy controls, internal consistency, and convergent and divergent validity with other psychological instruments.

Health professionals' familiarity and experience with providing clinical care for pediatric avoidant/restrictive food intake disorder

OBJECTIVE

The current study explored the experience and familiarity of pediatric health professionals with avoidant/restrictive food intake disorder (ARFID), and assessed the application of diagnostic criteria in a series of clinical vignettes.

METHOD

Pediatric health professionals were invited to complete an online survey. Data from 93 health professionals from medical and allied health roles who completed the survey were analyzed.

RESULTS

Respondents providing care for pediatric feeding/eating disorders were more likely to report familiarity with ARFID than those not typically providing care for feeding/eating disorders. Clinicians who had provided care for pediatric ARFID reported more confidence in clinical management of ARFID than did those who had not yet provided care for ARFID, though there were overall relatively low levels of confidence in providing care for ARFID. Respondents to the clinical vignettes were more likely to confer a diagnosis of ARFID when there were symptoms of both psychosocial impairment and weight loss than when there was psychosocial impairment alone.

DISCUSSION

The results suggest variability in current application of diagnostic criteria for ARFID, low confidence in clinical management of ARFID, and ambiguity in clinicians' judgments regarding whether psychosocial impairment is sufficient to meet a diagnosis of ARFID.

Psychological Risk Factors for the Development of Restrictive and Bulimic Eating Behaviors: A Polish and Vietnamese Comparison

The aim of this paper is to identify psychological factors which are culture specific or common predictors for restrictive and bulimic behaviors towards eating for young women raised in different cultures. The study included 661 young women from Poland (n = 233) and Vietnam (n = 428). Subjects filled-in the Eating Disorders Inventory (EDI-3) and the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS), and body measurements were collected to calculate anthropometric indices. Women form Vietnam were less satisfied with their appearance than were their Polish peers, but Vietnamese showed a lower level of preoccupation with being overweight and fear of obesity. Intercultural differences indicate that Vietnamese women show greater intensities for psychological variables, connected with restrictive and bulimic eating behaviors, verified in the research model: low self-esteem, personal alienation, interpersonal insecurity, interpersonal alienation, emotional dysregulation, interoceptive deficits, perfectionism and asceticism, and anxiety.

Gender identity, race/ethnicity and eating pathology in a treatment-seeking community sample

Despite the wide-reaching impact of eating disorders (EDs), less is known about eating pathology among individuals across racial/ethnic groups whose gender identity differs from the binary categorization. Examining ED pathology both across binary and minority-gender groups, and relative to racial/ethnic identification is necessary to inform screening and culturally-sensitive intervention efforts. This study investigated patterns of ED symptomology among youth and adults (N = 13658) who telephoned treatment centers in the United States when seeking clinical support for ED symptoms. Analyses examined data from participants who completed a semi-structured clinical interview. Results indicated that Anorexia nervosa was the most common diagnosis in each gender category and for a majority of race/ethnic groups; Black individuals had elevated rates of binge eating disorder. Compared to females, males were less likely to endorse all ED symptoms (ps < .001); gender minority status was also associated with decreased report of a majority of ED symptoms. Asian and Black individuals were less likely than Whites to endorse most ED symptoms. When compared to Whites, Hispanic/Latinx and Bi/Multi-racial participants did not demonstrate significant differences in presentation across a majority of ED symptoms. Overall findings suggest individuals with female gender and White race may seek treatment from an ED treatment facility with greater frequency than other demographic groups. Noted exceptions include Hispanic/Latinx and Bi/Multi-racial individuals, for whom ED pathology may be represented comparably to Whites. While findings confirm traditional patterns in gender and racial/ethnic representation in EDs, current study findings also underscore that EDs are not culture bound.

A test of the tripartite influence model of disordered eating among men

Studies of the Tripartite Influence Model conducted with female samples suggest that thinness-oriented pressures, internalization, and appearance comparisons may be risk factors for disordered eating. However, limited work has investigated this model among men utilizing measures specifically designed to assess both muscularity- and thinness-oriented processes, which characterize male body image concerns. To address this gap, the current study examined the Tripartite Influence Model of disordered eating among men using a battery of such measures. A convenience sample of 265 male undergraduates completed validated, self-report measures of disordered eating, muscularity- and thinness-oriented appearance pressures, internalization, and appearance comparisons. Path analyses supported a slightly modified version of the Tripartite Influence Model, indicating direct and indirect paths from sociocultural pressures to disordered eating via internalization and appearance comparisons. These results provide support for a version of the Tripartite Influence Model among men. Specifically, muscularity- and thinness-oriented pressures appear to be related to disordered eating among college men via indirect pathways involving thin internalization, muscular internalization, and appearance comparisons. Future work is needed, however, to examine whether the model would generalize to muscularity-oriented disordered eating.

Attentional engagement, appearance comparisons, and rumination as predictors of body dissatisfaction: Evaluation of a serial mediation model in men

Elevated body dissatisfaction is underpinned by an attentional bias towards images portraying appearance ideals. However, very little is known about the specific attentional mechanisms and mediating factors involved in this relationship in the context of male body dissatisfaction. The present study sought to replicate and extend on previous research among women showing that the relationship between attentional engagement bias and body dissatisfaction is sequentially mediated by appearance comparisons and rumination. Seventy undergraduate males completed an attentional task capable of independently assessing biased attentional engagement with images of muscular and non-muscular bodies followed by self-report measures of appearance comparisons, eating disorder-specific rumination, and body dissatisfaction. Results revealed that a heightened tendency to engage in appearance comparisons was associated with increased attentional engagement with muscular bodies, relative to non-muscular bodies. Moreover, a serial mediation analysis revealed that increased attentional engagement with muscular bodies was associated with appearance comparisons, which in turn were associated with eating disorder-specific rumination and, consequently, body dissatisfaction. The current findings replicate among men the serial mediation model of body dissatisfaction previously described among women and implicate heightened attentional engagement with idealized images as a potential pathway to body dissatisfaction in men.

Dissonance-based eating disorder prevention delivered in-person after an online training: A randomized controlled trial for Brazilian men with body dissatisfaction

OBJECTIVE

Few prevention programs have been developed and empirically evaluated to address eating disorder (ED) and muscle dysmorphia (MD) symptoms in men. Furthermore, new strategies for the broad implementation of available programs are needed. We investigated the acceptability and efficacy of a dissonance-based (DB) intervention for Brazilian undergraduate men with body dissatisfaction to target risk and protective factors for ED and MD symptoms (the Body Project: More Than Muscles) after an online training for facilitators.

METHOD

Participants were randomized to a two-session DB-intervention (n = 89) or assessment-only control (AOC) (n = 91), and completed validated measures assessing ED and MD risk and protective factors pre-intervention, post-intervention, and at 4- and 24-week follow-up post-intervention.

RESULTS

Acceptability ratings were highly favorable. Regarding efficacy, the DB condition demonstrated significantly greater decreases in ED and MD risk factors compared to AOC from pre-intervention to 4-week (p-values <.05, between-condition Cohen's d = 0.35-1.10) and 24-week follow-up (p-values <.05, between-condition Cohen's d = 0.33-0.78). Results at post-intervention were not significant, with the exception that body appreciation showed significantly greater improvements in the DB condition (post-intervention: p < .01, between-condition Cohen's d = 0.40; 4-week: p < .001, between-condition Cohen's d = 0.80; and 24-week follow-up: p < .001, between-condition Cohen's d = 0.58).

DISCUSSION

Results support the acceptability and efficacy of a DB-intervention delivered in-person after an online training for facilitators up to 24-week follow-up in Brazilian men.

Ethnic/racial and gender differences in body image disorders among a diverse sample of sexual minority U.S. adults

This study assessed the occurrence of probable eating disorders (EDs), ED symptoms, probable body dysmorphic disorder (BDD), BDD symptoms, drive for muscularity, and appearance and performance enhancement drug (APED) misuse, in an ethnically/racially diverse sample of 962 cisgender sexual minority (SM) individuals in the United States, aged 18-30 years old. The overall occurrence of probable ED, probable BDD, and APED misuse in the current sample was 32.7 %, 50.9 %, and 30.6 %, respectively. With respect to ethnicity/race, Hispanic SMs reported the highest rates of EDs, BDD, APED misuse, and drive for muscularity, and may therefore be particularly at risk for developing body image disorders (BIDs). With respect to gender, SM men reported significantly greater drive for muscularity and APED misuse compared to SM women, while SM women reported significantly higher occurrence of probable ED and ED symptoms. The occurrence of EDs, BDD, and APED misuse were higher among SMs in this sample compared to previous rates found among heterosexual samples, suggesting that SMs, regardless of gender and ethnicity/race, are vulnerable to experiencing BIDs and APED misuse. Future research is needed to identify the mechanisms that place SMs at (increased) risk for BIDs, which will aid prevention/intervention development.

Self-reported eating disorder psychopathology prevalence in community-based female and male Albertans: Gender and age group comparisons

OBJECTIVE

We describe and compare eating disorder (ED) psychopathology prevalence in Canadian females and males across five age groups.

METHOD

This secondary data analysis study used the Eating Disorder Examination Questionnaire (EDE-Q) to assess ED psychopathology in 1,316 Alberta community-based female and male participants, aged 15 to 71.

RESULTS

Overall, 15.3% of female and 8.2% of male participants reported clinically-significant ED disturbances. Female participants reported greater global ED psychopathology than male participants, except older men and women aged 65-71, who reported similar, relatively low levels of global ED psychopathology. Women aged 65-71 endorsed less global ED psychopathology than younger females. More females than males reported regular binge eating and self-induced vomiting, whereas other ED behaviors were endorsed at similar rates.

DISCUSSION

This large-scale study, the first involving a Canadian sample, contributes to a small literature on ED psychopathology in community-based samples. The finding that 15% of female and 8% of male Albertans aged 15 to 71 endorsed clinically-significant ED disturbances is concerning; however, women aged 65-71 reported lower ED psychopathology than younger females. Gender and age differences were observed in global ED psychopathology. Routine ED screening of non-clinical adolescents and adults is warranted to permit prevention and early intervention.

Dietary restraint patterns and eating disorder help-seeking

OBJECTIVE

Determine whether gender differences exist in associations among central barriers to and facilitators of eating disorder (ED) help-seeking-ED stigma, negative affect, perceived ED treatment need-as a function of individuals' probability of classification within empirically derived groups characterized by different dietary restraint patterns.

METHOD

As part of the cross-sectional, multi-institute Healthy Bodies Study, women (n = 2215) and men (n = 986) attending three colleges and universities in 2015 completed measures of ED symptoms, affect, and ED help-seeking in an online survey. Structural equation mixture modeling was used to (1) classify women and men, separately, into distinct classes characterized by unique dietary restraint patterns and (2) test associations among the three ED help-seeking barriers and facilitators within each class.

RESULTS

Five dietary restraint symptoms (food amount limiting attempts, fasting, food avoidance, following food/diet rules, desiring an empty stomach) clustered within four classes among women and three classes among men, which were characterized by qualitative and quantitative similarities and differences. Further, opposite patterns were generally found in associations among the ED help-seeking barriers and facilitators for women versus men as a function of the way dietary restraint symptoms clustered within each class. For example, bivariate associations between worse ED stigma and negative affect relative to greater perceived ED treatment need were both significant only among women in their lowest restraint severity class, whereas these associations were both significant among men in their highest severity class.

DISCUSSION

These findings can help to increase the reach of ED intervention efforts, including increasing ED help-seeking rates.

LEVEL OF EVIDENCE

Level V, cross-sectional descriptive study.

Adaptation and validation of the Eating Disorder Examination-Questionnaire in English among urban Indian adolescents

OBJECTIVE

Eating pathology is a salient issue in India, with clinical features reported among adults and adolescents. However, there are currently no validated measures of disordered eating in the Indian context. The present study therefore aimed to validate a culturally appropriate English language version of the Eating Disorder Examination Questionnaire (EDE-Q), a widely used measure, among adolescents in India.

METHOD

We adapted and examined the factor structure, reliability, and construct validity of the EDE-Q among an urban sample of 1,413 Indian adolescents (mean age = 13 years; 45% girls).

RESULTS

In contrast to the original four-factor model, exploratory factor analysis identified a two-factor solution for girls and boys, which was verified by confirmatory factor analysis; a "Preoccupation and Control" subscale and a "Weight and Shape Concerns" subscale. The total scale comprised 15 items for girls and 18 items for boys. Test-retest reliability and internal consistency were satisfactory for the girls' and boys' scales (Cronbach's α = .91 for both) and their comprising subscales (αs ≥ .80). Concurrent validity was established through medium-high significant correlations with measures of body image and internalization of appearance ideals. Combining items common to both versions of the scale led to a psychometrically acceptable model which was largely invariant across both genders, thus facilitating gendered comparison.

DISCUSSION

Findings indicate the reliability and validity of the EDE-Q among English-speaking urban Indian adolescents. This will facilitate further research examining the prevalence and nature of eating pathology among adolescents in India.

Diagnostic Agreement between Physicians and a Consultation-Liaison Psychiatry Team at a General Hospital: An Exploratory Study across 20 Years of Referrals

Consultation-liaison psychiatry (CLP) manages psychiatric care for patients admitted to a general hospital (GH) for somatic reasons. We evaluated patterns in psychiatric morbidity, reasons for referral and diagnostic concordance between referring doctors and CL psychiatrists. Referrals over the course of 20 years (2000-2019) made by the CLP Service at Modena GH (Italy) were retrospectively analyzed. Cohen's kappa statistics were used to estimate the agreement between the diagnoses made by CL psychiatrist and the diagnoses considered by the referring doctors. The analyses covered 18,888 referrals. The most common referral reason was suspicion of depression (n = 4937; 32.3%), followed by agitation (n = 1534; 10.0%). Psychiatric diagnoses were established for 13,883 (73.8%) referrals. Fair agreement was found for depressive disorders (kappa = 0.281) and for delirium (kappa = 0.342), which increased for anxiety comorbid depression (kappa = 0.305) and hyperkinetic delirium (kappa = 0.504). Moderate agreement was found for alcohol or substance abuse (kappa = 0.574). Referring doctors correctly recognized psychiatric conditions due to their exogenous etiology or clear clinical signs; in addition, the presence of positive symptoms (such as panic or agitation) increased diagnostic concordance. Close daily collaboration between CL psychiatrists and GH doctors lead to improvements in the ability to properly detect comorbid psychiatric conditions.

Evaluating gender bias in an eating disorder risk assessment questionnaire for athletes

Due to stigma, eating disorders are under-researched, underdiagnosed and undertreated among men. This is particularly pertinent among athletes, as athletic goals are a major risk factor for disordered eating in men. This gender stereotype may be reinforced by eating disorder risk assessment tools that better reflect female symptoms. We examine an eating disorder risk assessment questionnaire in a population of athletes to assess both (1) gender bias in individual items and (2) gender differences on a cognitive and behavioral subscale, identified through a factor analysis. Controlling for eating disorder risk, we found that female gender significantly predicted high risk scores on four items; male gender significantly predicted high risk scores on four other items. We also found that women were more likely to score above the median on a cognitive subscale than men with the same level of eating disorder risk, while men were more likely to score above the median on a behavioral subscale. These results may be applied practically to allow eating disorder risk assessment tools to better capture eating disorder risk independent of gender. These methods may be applied to other questionnaires and other social identities, to expand the scope of eating disorder research and treatment.

Associations between legal performance-enhancing substance use and future cardiovascular disease risk factors in young adults: A prospective cohort study

BACKGROUND

Legal performance-enhancing substances (PES), such as creatine, are commonly used by adolescents and young adults. As PES are mostly unregulated by the US Food and Drug Administration, there has been limited empirical attention devoted to examining their long-term safety and health outcomes. Preliminary studies have demonstrated associations between PES use and severe medical events, including hospitalizations and death. PES could be linked to cardiovascular disease (CVD), the most common cause of mortality in the US, by altering the myocardium, vasculature, or metabolism. The objective of this study was to examine prospective associations between the use of legal PES in young adulthood and CVD risk factors at seven-year follow-up.

MATERIALS AND METHODS

Nationally representative longitudinal cohort data from the National Longitudinal Study of Adolescent to Adult Health, Waves III (2001-2002) and IV (2008), were analyzed. Regression models determined the prospective association between the use of legal PES (e.g. creatine monohydrate) and CVD risk factors (e.g. body mass index, diabetes, hypertension, hyperlipidemia), adjusting for relevant covariates.

RESULTS

Among the diverse sample of 11,996 male and female participants, no significant differences by PES use in body mass index, diabetes, hypertension, or hyperlipidemia were noted at Wave III. In unadjusted comparisons, legal PES users (versus non-users) were more likely to be White, be male, be college educated, drink alcohol, and engage in weightlifting, exercise, individual sports, team sports, and other strength training. There were no significant prospective associations between legal PES use at Wave III and body mass index, hemoglobin A1c, systolic and diastolic blood pressure, and cholesterol (total, HDL, LDL, triglycerides) deciles at seven-year follow-up (Wave IV), adjusting for demographics, health behaviors, and Wave III CVD risk factors. Similarly, there were no significant prospective associations between legal PES use and diabetes, hypertension, or hyperlipidemia based on objective measures or self-reported medications and diagnoses, adjusting for demographics, health behaviors, and Wave III CVD risk.

CONCLUSIONS

We do not find evidence for a prospective association between legal PES use and CVD risk factors in young adults over seven years of follow-up, including BMI, diabetes, hypertension, or hyperlipidemia. It should be noted that legal PES use was operationalized dichotomously and as one broad category, which did not account for frequency, amount, or duration of use. Given the lack of regulation and clinical trials data, observational studies can provide much needed data to inform the safety and long-term health associations of legal PES use and, in turn, inform clinical guidance and policy.

Theoretical and Methodological Considerations for Research on Eating Disorders and Gender

Gender is a relevant factor in the etiology of eating disorders (ED) as evidenced by gender-specific components of disordered eating and by the high risk of ED among transgender individuals, in addition to other factors. However, research on connections between ED and gender identity are limited. Researchers who produce explanatory models, content themselves with faulting the sociocultural ideal of slimness for women, but they fail to grasp the connection between culture, gender and the body and they fall short of integrating this perspective into existing psychological knowledge about ED. Psychological research informed by feminist theory has begun to bridge this gap, but this growing area of research needs to be further developed and should include an understanding of ED in persons with all gender identities. This article expands the discussion of gender and ED, by grounding ED in an understanding of gender itself and by discussing methodological implications of this understanding.

Trends in the prevalence and disability-adjusted life years of eating disorders from 1990 to 2017: results from the Global Burden of Disease Study 2017

AIM

Eating disorders have increasingly become a public health concern globally. This study aimed to reveal the burden of eating disorders at the global, regional and national levels using the Global Burden of Disease (GBD) Study 2017 data.

METHODS

We extracted the age-standardised rates (ASRs) of prevalence and disability-adjusted life years (DALYs) and their 95% uncertainty intervals (UIs) of eating disorders, including anorexia nervosa and bulimia nervosa, between 1990 and 2017 from the GBD 2017 data. The estimated annual percentage changes (EAPCs) were calculated to quantify the secular trends of the burden of eating disorders.

RESULTS

The ASRs of prevalence and the DALYs of eating disorders continuously increased worldwide from 1990 to 2017 by an average of 0.65 (95% UI: 0.59-0.71) and 0.66 (95% UI: 0.60-0.72), respectively. The burden of eating disorders was higher in females than in males, but the increment in ASRs was greater in males than in females over time. In 2017, the highest burden of eating disorders was observed in the high sociodemographic index (SDI) regions, especially Australasia (ASR of prevalence = 807.13, 95% UI: 664.20-982.30; ASR of DALYs = 170.74, 95% UI: 113.43-244.14, per 100 000 population), Western Europe and high-income North America. However, the most significant increment of the burden of eating disorders was observed in East Asia (EAPC for prevalence = 2.23, 95% UI: 2.14-2.32; EAPC for DALYs = 2.22, 95% UI: 2.13-2.31), followed by South Asia. An increasing trend in the burden of eating disorders at the national level was observed among most countries or territories. The countries with the top three highest increasing trends were Equatorial Guinea, Bosnia and Herzegovina and China. Positive associations were found between the burden estimates and the SDI levels in almost all geographic regions during the observed 28-year period. We also found that the human development indexes in 2017 were positively correlated with the EAPCs of the ASRs of prevalence (ρ = 0.222, P = 0.002) and DALYs (ρ = 0.208, P = 0.003).

CONCLUSION

The highest burden of eating disorders remains in the high-income western countries, but an increasing trend was observed globally and in all SDI-quintiles, especially in Asian regions that were highly populous. These results could help governments worldwide formulate suitable medical and health policies for the prevention and early intervention of eating disorders.

Preventing Nutritional Disorders in Adolescents by Encouraging a Healthy Relationship With Food

Nutritional disorders, including overweight, underweight, and/or nutrient deficiency, are a significant cause of morbidity and mortality. These disorders are frequently related to abnormal patterns of eating and/or physical activity, which commonly begin in adolescence and persist into adulthood. Abnormal eating and exercise behaviors may stem from an unhealthy relationship with food, which often takes root in preadolescence or early adolescence. To prevent eating disorders, overweight, underweight, and nutritional deficiencies in adolescence and beyond, health care providers need to proactively support early adolescents and their caregivers to develop a healthy relationship with food and their bodies. Anticipatory guidance, nutrition and exercise counseling, and encouragement of body positivity and healthy self-image during the vulnerable period of early adolescence can prevent maladaptive behaviors from emerging later on. Advocacy beyond the health care setting is also needed to ensure that adolescents are exposed to consistent and positive nutritional messaging. In this position article, authors from both the Nutrition/Obesity Committee and the Eating Disorder Committee of the Society of Adolescent Health and Medicine provide practical recommendations for health care professionals to guide their young patients and caregivers toward a flexible, balanced, and satisfying approach to nutrition that will lead to physical and emotional wellness throughout their lifetimes.

Uso da mídia social e sua associação com comportamentos alimentares disfuncionais em estudantes de Nutrição

RESUMO Objetivos: Avaliar a associação entre o uso da mídia social e comportamentos alimentares disfuncionais e identificar preditores desses comportamentos. Métodos: Estudo realizado com 207 estudantes de Nutrição. Foram aplicadas três medidas para obter dados sociodemográficos, uso da mídia social e comportamentos alimentares disfuncionais (Eating Attitudes Test-26). A associação entre o uso da mídia social e os comportamentos alimentares disfuncionais foi verificada pelo teste qui-quadrado de Pearson (p < 0,05). Regressão logística binária foi conduzida para avaliar preditores dos comportamentos alimentares disfuncionais, considerando as razões de chance. Resultados: Comportamentos alimentares disfuncionais foram verificados em 27,9% dos estudantes de Nutrição. As variáveis de uso da mídia social associadas aos comportamentos alimentares disfuncionais incluem o hábito de acompanhar dicas alimentares e de consumir alimentos sugeridos pela mídia, o tempo de uso, seguir dieta e/ou orientação nutricional, motivação para seguir uma dieta sem um acompanhamento nutricional e consumo de alimentos e fármacos para a perda de peso. Os preditores dos comportamentos alimentares disfuncionais foram: “Já consumi alimentos propostos pela mídia com o intuito de perda de peso” e “Ao observar corpos disseminados como ‘belos’ pela mídia, me sinto motivado a seguir uma dieta sem um acompanhamento nutricional adequado por um nutricionista”. Conclusões: Diversas crenças e comportamentos orientados ao uso da mídia social estão associados aos comportamentos alimentares disfuncionais em estudantes de Nutrição, em que se destacam maiores razões de chances para o desenvolvimento de comportamentos de risco quando há consumo de alimentos para perda de peso e motivação para seguir dieta sem acompanhamento nutricional, mesmo por esse grupo.

Implicit and explicit motivational responses to high- and low-calorie food in women with disordered eating

Eating disorders and their symptoms are thought to be associated with altered motivational responding to food. Binge eating may relate to increased reward reactivity, restrictive eating may be associated with increased threat and/or decreased reward reactivity, and the combination of these symptoms within an individual may be linked to motivational conflict to food. Using both implicit (i.e., physiological) and explicit (i.e., self-reported) measures, we tested these hypotheses in 88 women with binge eating only, restrictive eating only, both binge eating and restrictive eating, or no eating pathology. Participants viewed and rated high-calorie food, low-calorie food, and emotional images while startle eye blink and postauricular reflexes were measured. Arousal and craving, but not valence, ratings were significantly greater for high- than low-calorie food. Startle blink reflexes during all food images were significantly lower than during neutral images, whereas only high-calorie foods related to greater postauricular reactivity than neutral images. Eating pathology group did not predict implicit and explicit motivational reactions to food. Exploratory dimensional analyses revealed that rating low-calorie foods as lower on craving predicted endorsement of restrictive eating, while rating low-calorie foods as lower on valence and arousal, and experiencing lower postauricular reactivity to high-calorie foods minus neutral images, predicted greater frequency of restrictive eating episodes. Decreased implicit and explicit appetitive motivation to high- and low-calorie food may relate to the presence and frequency of restrictive eating. Future longitudinal research should investigate whether decreased appetitive responding to food is a risk factor for, versus consequence of, restrictive eating.

The brief (seven-item) eating disorder examination-questionnaire: Evaluation of a non-nested version in men and women

OBJECTIVE

Several recent studies have examined the psychometric properties of brief measures of eating disorder attitudes based on the Eating Disorder Examination Questionnaire (EDE-Q). A seven-item version (the EDE-Q7) has been proposed but, as yet, has only been investigated by looking at the items when presented as part of the longer EDE-Q (i.e., as a nested version). The current study presented the EDE-Q7 as a standalone instrument and examined factor structure fit and measurement invariance across male and female genders.

METHODS

University students (244 women; 155 men; 1 did not identify with either gender) completed questionnaires as part of two independent studies. All individuals completed the EDE-Q7 and measures of eating disorder behaviors. In a mixed-gender subsample (n = 286), measures of depression and eating disorder-specific quality of life were also included. Confirmatory factor analysis of the EDE-Q7 was conducted on males and females independently, in addition to estimates of internal consistency reliability and validity. Measurement invariance was assessed through multigroup confirmatory factor analysis.

RESULTS

The EDE-Q7 demonstrated good internal consistency and findings supported measurement invariance by gender. In a mixed-gender subsample, the measure showed positive associations with depression and both eating disorder behaviors and eating disorder-specific quality of life.

DISCUSSION

The present study adds to the literature supporting the psychometric properties of the EDE-Q7, extending this to use of the questionnaire as a standalone instrument. Measurement invariance suggests that the measure may be appropriate for college-age men and women, although future studies should establish psychometric properties more fully.

A longitudinal examination of body-checking behaviors and eating disorder pathology in a community sample of adolescent males and females

OBJECTIVE

Related to the cognitive-behavioral theory of eating disorders, body checking has gained increasing recognition as both a maintaining factor for eating disorders and an important target for treatment. However, it is unclear whether body-checking behaviors contribute to the development of disordered eating, or if these behaviors develop as a response to experiencing eating disorder thoughts and behaviors. This study aims to examine the relationships between body-checking behaviors and eating disordered thoughts and behaviors in adolescent females and males in the community over time.

METHODS

Participants included 238 adolescents (n = 104 males, n = 134 females, M_age = 16.5 years) recruited from high schools in British Columbia, Canada, who completed the Eating Disorder Examination Questionnaire and Body Checking Questionnaire at baseline (T1) and again approximately 4 months later (T2).

RESULTS

After controlling for baseline levels of eating pathology and body mass index (BMI), body checking at T1 predicted increases in eating pathology for both males and females. In contrast, after controlling for baseline levels of body checking and BMI, eating pathology at T1 did not predict changes in body checking for females, but it did for males. Findings suggest that, among adolescents, engaging in body-checking behaviors may increase risk for disordered eating.

DISCUSSION

If supported by further research, targeting body-checking behaviors in prevention programs may be warranted.

Validation of a Spanish Version of the Physical Appearance Comparison Scales

Physical appearance comparison has been widely studied because of its strong relationship with body dissatisfaction and disordered eating. The main objective of this study was to validate the physical appearance comparison scales (PACS-Revised and PACS-3) in a sample of Spanish men and women and examine their psychometric properties. The sample consisted of 1151 participants (age M = 22.31, SD = 3.40). A unidimensional structure was corroborated in the PACS-R, and three factors in the PACS-3 (proximal, distal, and muscularity comparisons). The PACS-R and PACS-3 showed full scalar invariance across sex. The internal consistency for the PACS-R and subscales of PACS-3 were satisfactory. Positive statistically significant relationships were found with measures of disordered eating (EAT-26) and dysmorphic concern (DCQ). Hierarchical multiple regression analyses demonstrated that the PACS-3 discretely improved the prediction of disordered eating over PACS-R, but did not show improvement in the prediction of dysmorphic concern beyond the PACS-R. These findings suggest that the PACS-R and PACS-3 may be useful tools for evaluating the tendency of men and women to compare their physical appearance.

Where identities converge: The importance of intersectionality in eating disorders research

Disparities in eating disorder (ED) risk, diagnosis, and treatment for those who occupy multiple marginalized social identities (e.g., combined racial/ethnic and sexual minority statuses), underscore the need for advancing multicultural research in the ED field. In this article, we argue that intersectionality-informed approaches, which examine the ways in which one's multiple social identities interact to inform risk for ED outcomes, offer an established framework for identifying frequently underserved individuals who may be at greatest risk for EDs. We highlight preliminary intersectional research in EDs and offer suggestions for further progression. In particular, we encourage future intersectionality-informed research to incorporate a broader range of social identities (e.g., age, ability status), consider the ways in which these identities may be dimensional and fluid, and embrace strengths-based approaches to illuminate dimensions of identity that may serve as protective factors. To support such research, we describe quantitative and qualitative methods for pursuing questions of intersectionality in ED investigations. Given the success of intersectionality-informed research in other areas of psychopathology and its relevance to ED as suggested by initial research, the continued pursuit of these approaches in EDs has high potential to improve identification and treatment for patients who have too often been overlooked.

Traits of orthorexia nervosa and muscle dysmorphia in Italian university students: a multicentre study

PURPOSE

This study aimed to evaluate the prevalence of traits of orthorexia nervosa (ON) and muscle dysmorphia (MD) in a group of undergraduates, investigate the associations between the risk of these conditions and the type of university course attended, the individual characteristics (gender, BMI, amount of physical activity, supplements and medicines use, dieting) and the risk of eating disorders (EDs).

METHODS

A self-reported questionnaire consisting of a socio-demographic section and three tests validated for the evaluation of a risk of ON (ORTO-15), MD (MDDI-ITA) and EDs (EAT-26) was completed by 918 students from three Italian universities.

RESULTS

29.0% of participants demonstrated traits of ON and 5.0% of MD, without differences in prevalence in the three areas of study investigated (health-scientific, economic-humanistic, sport sciences); students of sport sciences exhibited a significantly higher score for MDDI-ITA (F = 6.493, p = 0.002). Participants with ON and MD traits were more on a diet (OR = 0.47, p ≤ 0.001 and OR = 0.428, p = 0.020, respectively) and showed a higher prevalence of EDs risk (OR = 3.55, p < 0.001 and OR = 10.23, p ≤ 0.001, respectively). The simultaneous presence of ON, MD, and EDs traits was seen in 5.4% of the students and the three test scores were correlated.

CONCLUSIONS

The prevalence of ON and MD traits was found similar to that reported in the literature on undergraduates. Some associations observed improvement in the knowledge about these conditions, especially the association of participants with ON and MD traits with dieting and EDs traits and the correlation of the three test scores suggests a connection among these potential conditions.

Legal Performance-Enhancing Substances and Substance Use Problems Among Young Adults

BACKGROUND

Legal performance-enhancing substance(s) (PES) (eg, creatine) are widely used among adolescent boys and young men; however, little is known about their temporal associations with substance use behaviors.

METHODS

We analyzed prospective cohort data from the National Longitudinal Study of Adolescent to Adult Health, Waves I to IV (1994-2008). Logistic regressions were used to first assess adolescent substance use (Wave I) and use of legal PES (Wave III) and second to assess use of legal PES (Wave III) and subsequent substance use-associated risk behaviors (Wave IV), adjusting for potential confounders.

RESULTS

Among the sample of 12 133 young adults aged 18 to 26 years, 16.1% of young men and 1.2% of young women reported using legal PES in the past year. Adolescent alcohol use was prospectively associated with legal PES use in young men (odds ratio 1.39; 95% confidence interval [CI] 1.13-1.70). Among young men, legal PES use was prospectively associated with higher odds of problematic alcohol use and drinking-related risk behaviors, including binge drinking (adjusted odds ratio [aOR] 1.35; 95% CI 1.07-1.71), injurious and risky behaviors (aOR 1.78; 95% CI 1.43-2.21), legal problems (aOR 1.52; 95% CI 1.08-2.13), cutting down on activities and socialization (aOR 1.91; 95% CI 1.36-2.78), and emotional or physical health problems (aOR 1.44; 95% CI 1.04-1.99). Among young women, legal PES use was prospectively associated with higher odds of emotional or physical health problems (aOR 3.00; 95% CI 1.20-7.44).

CONCLUSIONS

Use of legal PES should be considered a gateway to future problematic alcohol use and drinking-related risk behaviors, particularly among young men.

Predicting eating disorders from Internet activity

OBJECTIVE

Eating disorders (EDs) compromise the health and functioning of affected individuals, but it can often take them several years to acknowledge their illness and seek treatment. Early identification of individuals with EDs is a public health priority, and innovative approaches are needed for such identification and ultimate linkage with evidence-based interventions. This study examined whether Internet activity data can predict ED risk/diagnostic status, potentially informing timely interventions.

METHOD

Participants were 936 women who completed a clinically validated online survey for EDs, and 231 of them (24.7%) contributed their Internet browsing history. A machine learning algorithm used key attributes from participants' Internet activity histories to predict their ED status: clinical/subclinical ED, high risk for an ED, or no ED.

RESULTS

The algorithm reached an accuracy of 52.6% in predicting ED risk/diagnostic status, compared to random decision accuracy of 38.1%, a relative improvement of 38%. The most predictive Internet search history variables were the following: use of keywords related to ED symptoms and websites promoting ED content, participant age, median browsing events per day, and fraction of daily activity at noon.

DISCUSSION

ED risk or clinical status can be predicted via machine learning with moderate accuracy using Internet activity variables. This model, if replicated in larger samples where it demonstrates stronger predictive value, could identify populations where further assessment is merited. Future iterations could also inform tailored digital interventions, timed to be provided when target online behaviors occur, thereby potentially improving the well-being of many individuals who may otherwise remain undetected.

Development and Validation of the Eating Disorders Screen for Athletes (EDSA): A Brief Screening Tool for Male and Female Athletes

OBJECTIVES

To develop and validate the Eating Disorders Screen for Athletes (EDSA), a brief eating disorders screening tool for use in both male and female athletes.

METHODS

Data from Division I athletes at a Midwestern university (N=434) were used to conduct exploratory factor analysis (EFA) by gender. Data from athletes competing at various levels at universities across the United States (N=862) were then used to conduct confirmatory factor analysis (CFA) and receiver operator characteristic (ROC) curve analysis by gender. Athletes from a range of lean and non-lean sports were included. Gender-specific empirically derived cut-offs on the Eating Disorder Examination-Questionnaire were used to classify high eating disorder risk for ROC curve analysis. Measurement invariance by gender, level of competition, and sport type was also examined.

RESULTS

A six-item, one-factor structure for the EDSA was supported by EFA and CFA in both genders, and internal consistency was good for both male (α=. 80) and female athletes (α=.86). ROC curve analyses indicated that the EDSA was highly accurate in predicting eating disorder risk status and identified a score of 3.33 as the optimal cut-off for both male (sensitivity=.96, specificity=.80) and female athletes (sensitivity=.96, specificity=.64). Results also supported strong measurement invariance for the EDSA by gender, level of competition (Division I versus club), and sport type (lean versus non-lean).

CONCLUSIONS

The EDSA shows promise as a brief screening tool to identify male and female athletes at risk for eating disorders.

Who's the 'bigger' man? Parsing the relationships between masculinity and men's muscularity dissatisfaction

Muscularity dissatisfaction is documented to be a pervasive phenomenon among men. While previous studies have examined theoretically relevant predictors of muscularity dissatisfaction, such as adherence to traditional masculine norms, to the best of our knowledge we are not aware of empirical research that has assessed how perceived discrepancies in one's level of masculinity may also be associated with these concerns. Therefore, the objective of this study was to determine whether perceived deficits in masculinity bear predictive utility over and above adherence to traditional masculine norms in the context of muscularity dissatisfaction. An online survey that included measures assessing the aforementioned constructs was completed by 390 university and community adult men. A hierarchical regression analysis showed that while adherence to masculine norms was associated with increased muscularity dissatisfaction, masculine role discrepancy (and attendant stress) were particularly strong predictors of muscularity dissatisfaction. Our findings make a novel contribution to the male body image literature by demonstrating the relative importance of perceived discrepancies in masculinity, and related stress, in the context of muscularity dissatisfaction. Pending replication in relevant clinical samples using prospective designs, this study provides preliminary evidence that masculine role discrepancies may be promising targets to help allay muscularity concerns among men.

A review and integrated theoretical model of the development of body image and eating disorders among midlife and aging men

Etiological models of the development of eating disorders among midlife and aging men are lacking. The present study provides a review and integration of existing theoretical frameworks and empirical data relevant to the examination of eating pathology in this population and introduces an integrated model of risk and protective factors for the development of eating disorder symptoms. Several etiological models of eating pathology that have gained some empirical support, or present relevance to this population, are briefly reviewed including sociocultural theory, objectification theory, social identity theory, positive body image and the developmental theory of embodiment, and existential and terror management theory, and finally biologically based theories. In addition, these frameworks were extended to account for developmental and gender-specific factors that may influence the development of eating disorders. An integrated model of risk and protective factors that brings together critical elements of these extended theoretical frameworks is presented, with the goal of guiding and stimulating research in this neglected group.

Factor structure of the Eating Disorder Examination - Questionnaire among heterosexual and sexual minority males

Eating disorder (ED) pathology is increasingly recognized among males; however, presentations within males differ from traditional descriptions of ED pathology in females. Additionally, experiences of ED pathology differ between sexual minority (SM) and heterosexual males. These differences suggest that existing ED assessments, which are primarily based on female samples, do not adequately capture ED pathology in SM and heterosexual males. The Eating Disorder Examination-Questionnaire (EDE-Q) is a commonly used assessment of ED pathology; however, at present the factor structure of this instrument in SM and heterosexual males is unclear. This study aimed to determine the most appropriate factor structure of the EDE-Q by evaluating proposed factor structures in a large, non-clinical sample consisting of heterosexual and SM men. Additionally, this study examined differences in the factor structures and severities of ED pathology between SM and heterosexual males. Confirmatory Factor Analyses examining existing factor structures of the EDE-Q indicated that the brief three-factor model was the best fitting model for both heterosexual and SM males. Subsequent comparisons of factor scores between groups indicated that SM males in our sample experienced higher levels of dietary restraint, overvaluation of shape and weight, and body dissatisfaction than heterosexual males. Results provide preliminary support for the use of the brief three-factor model of the EDE-Q when assessing ED pathology among SM and heterosexual males in non-clinical research settings.

Alcohol consumption and risk for feeding and eating disorders in adolescence: The mediating role of drinking motives

BACKGROUND

A complex and bidirectional association has been assumed between feeding and eating disorders (FEDs) and alcohol consumption. Previous research has demonstrated that alcohol use among individuals with different forms of FEDs is more frequently motivated by two subtypes of internal drinking motives: coping and enhancement motives. Namely, these individuals might use alcohol primarily to regulate internal states, such as to mitigate negative emotions or enhance positive emotions.

OBJECTIVES

The present study investigated the mediating role of internal drinking motives on the association between risk for FEDs and alcohol consumption over the effects of relevant covariates, such as depressive symptoms or body mass index (BMI).

METHODS

Hungarian data of the European School Survey Project on Alcohol and Other Drugs (ESPAD) from 2015 were used. The final sample included responses from 5457 adolescents (50% males; mean age: 16.62 years). Validated self-report psychometric instruments assessed the level of alcohol use, depressive symptoms and risk for FEDs, and drinking motives.

RESULTS

Risk for FEDs presented a significant positive relationship with internal drinking motives and alcohol use. In the mediation analysis, a significant indirect effect was identified between risk for FEDs and alcohol use via internal drinking motives among females.

CONCLUSIONS

Results demonstrated that risk for FEDs was positively associated with internal drinking motives and alcohol use. An indirect effect of risk for FEDs on alcohol consumption via internal drinking motives was discriminated over the impact of depressive symptoms. However, the latter relationship was only found among females which may highlight the gender differences in the relationship between risk for FEDs and alcohol use.

Eating disorders in adolescent boys and young men: an update

PURPOSE OF REVIEW

To review the recent literature on eating disorders and disordered eating behaviors among adolescent boys and young men, including epidemiology, assessment, medical complications, treatment outcomes, and special populations.

RECENT FINDINGS

Body image concerns in men may involve muscularity, and muscle-enhancing goals and behaviors are common among adolescent boys and young men. Recent measures, such as the Muscularity Oriented Eating Test (MOET) have been developed and validated to assess for muscularity-oriented disordered eating. Medical complications of eating disorders can affect all organ systems in male populations. Eating disorders treatment guidance may lack specificity to boys and men, leading to worse treatment outcomes in these population. Male populations that may have elevated risk of eating disorders and disordered eating behaviors include athletes and racial/ethnic, sexual, and gender minorities.

SUMMARY

Eating disorders and disordered eating behaviors in boys and men may present differently than in girls and women, particularly with muscularity-oriented disordered eating. Treatment of eating disorders in boys and men may be adapted to address their unique concerns.

Eating Disorders in Males: An 8-Year Population-Based Observational Study

The objective of the study was the realistic evaluation of the prevalence of eating disorders (ED) among Polish men who sought treatment through the National Health Fund (NFZ) in the years 2010–2017. According to ICD-10, four types of ED were analyzed: anorexia nervosa—AN (F50.0), atypical anorexia nervosa (F50.1), bulimia nervosa—BN (F50.2), and atypical bulimia nervosa (F50.3).

The NFZ database was used. The ED groups were defined according to ICD-10 codes. Demographic data were collected from the web page of Statistics Poland (GUS). The annual prevalence of EDs was estimated, and the age groups were categorized into nine groups. For the incidence of EDs in male patients in the years 2010–2017, relative risk (RR) with 95% confidence interval (95% CI) was calculated.

The frequency trend of AN in males remains relatively stable. AN occurred mainly in young men (between 11 and 30 years). It was noted that AN affected approximately 100 men in each year of observation, while atypical anorexia nervosa affected about 40 men. In 2017, the RR for EDs in young males was 0.041 (95% CI [0.033, 0.051]). Bulimia was relatively rare (about 35 males each year).

The incidence of EDs in males is a relatively constant phenomenon. The real number of male patients with EDs may be higher. The current conceptualizations of ED pathology should be modified and better adapted to men. Clinical guidelines for specialists working with males with EDs should be developed.

Eating Disorders in Males: How Primary Care Providers Can Improve Recognition, Diagnosis, and Treatment

Eating disorders are complex and multifactorial illnesses that affect a broad spectrum of individuals across the life span. Contrary to historic societal beliefs, this disorder is not gender-specific. Lifetime prevalence of eating disorders in males is on the rise and demanding the attention of primary care providers, as well as the general population, in order to negate the potentially life-threatening complications. Current literature has continued to reinforce the notion that eating disorders predominately affect females by excluding males from research, thereby adding to the void in men-centered knowledge and targeted clinical care. To determine what is currently known about eating disorders among males, a scoping review was undertaken, which identified 15 empirical studies that focused on this topic. Using the Garrard matrix to extract and synthesize the findings across these studies, this scoping review provides an overview of the contributing and constituting factors of eating disorders in males by exploring the associated stigmas, risk factors, experiences of men diagnosed with an eating disorder, and differing clinical presentations. The synthesized evidence is utilized to discuss clinical recommendations for primary care providers, inclusive of male-specific treatment plans, as a means to improving care for this poorly understood and emerging men’s health issue.

Changes in disordered eating behaviors over 10 or more years: A meta-analysis

OBJECTIVE

The present meta-analysis evaluated changes in individuals' risk of engaging in distinct disordered eating behaviors (DEBs) in the long-term.

METHOD

Longitudinal studies assessing changes in DEBs via ≥2 assessments with a time lag of ≥10 years were included. Risk ratios were calculated for baseline to 10-14.9-year (M = 11.04) follow-up and baseline to ≥15-year (M = 18.62) follow-up changes in the use of binge eating, multiple purging, self-induced vomiting, laxatives, diuretics, diet pills, compensatory exercising, fasting/dieting, and multiple DEBs; Cohen's d was used for continuous binge-eating plus purging variable changes. Subgroup and meta-regression analyses tested whether eating disorder (ED) clinical sample versus nonclinical sample status, female versus male sex/gender, higher versus lower study bias, and baseline mean age and body mass index influenced overall effect magnitude for analyses with sufficient data.

RESULTS

Seventeen studies (26 [sub]samples) were included. Overall, individuals' risk of engaging in various restrictive eating and other compensatory behaviors decreased over time and the magnitudes of risk reductions for the use of certain compensatory DEBs were larger over longer follow-up durations. Specifically, for significant DEB change models, risk reductions spanned from 20.0-39.8% for 10-year follow-up and 24.7-74.8% for ≥15-year follow-up. However, nuances were found in the nature of these DEB changes as a function of DEB type, follow-up length, ED versus nonclinical sample composition, and baseline mean age.

CONCLUSIONS

These findings provide important information that can help identify treatment priorities and suggest that targeted and tailored preventative ED treatments warrant consistent implementation at the community-level, particularly for youth.
