Men’s eating disorders – A literature review

Introduction and purpose: Eating disorders belong to the group of mental diseases characterized by significant somatic complications and high mortality. There is a common opinion that these disorders mainly affect women. Such assumptions may result in limited knowledge of the diagnosis and treatment of an eating disorder in the male population. The aim of this study is to summarize the current knowledge about eating disorders among men, including binge eating disorder (BED), anorexia nervosa (AN) and bulimia nervosa (BN). Description of the state of knowledge: It turns out that the problem of eating disorders among the male sex is not so rare- it is estimated that approximately 10 million US men will experience an eating disorder at some point in their lives. The most common eating disorder among men appears to be binge eating disorder (BED). Men are also more likely to report binge eating than women. AN and BN occur much less frequently than BED in the male population. The symptoms of anorexia nervosa and bulimia nervosa may differ between men and women. More and more often we observe a development of a certain type of muscle dysmorphia among men, the so-called “reverse anorexia". Eating disorders carry a number of medical complications such as cardiac disorders, electrolyte disturbances, digestive problems and skeletal disturbances. Therapeutic interventions in the treatment of male eating disorders should take into account gender-specific problems. Conclusions: The real number of men suffering from eating disorders may be underestimated due to the neglect of the problem in the context of the male gender. It also results in poorly developed diagnostic and support schemes for men struggling with this problem. More research is needed on the topic of eating disorders in this group of patients as it will help to develop better diagnostic and therapeutic regimens adapted to the male gender.

Reciprocal association between session-by-session change in overvaluation of shape and weight and session-by-session change in bulimia nervosa symptoms during cognitive behavior therapies

ABSTRACT Overvaluation of shape and weight (OSW) is supported as an important mechanism underlying improvement in bulimia nervosa (BN) during behavioral therapies (CBTs). It is not yet clear, however, whether changes in OSW temporally precede and prospectively predict changes in BN symptoms during CBTs, limiting the ability to establish causality. The present study is the first to examine whether session-by-session changes in OSW prospectively predict session-by-session changes in BN symptoms during CBTs and clinical outcomes at the end-of-treatment. Participants with BN (n = 44) who received 20 sessions of CBTs completed a brief survey at each session assessing OSW and BN symptom frequency during the past week. Results showed small but significant session-by-session reductions in OSW and BN symptoms during CBTs. Session-by-session improvements in OSW in any given week prospectively predicted reductions in restrictive eating, binge eating, and compulsive exercise in the following week but did not prospectively predict improvements in purging, while improvements in restrictive eating and compulsive exercise in any given week prospectively predicted reductions in OSW in the following week. Average session-by-session change in OSW during treatment was positively associated with remission status and improvements in eating pathology at the end-of-treatment. Changes in OSW temporally precede and prospectively predict changes in BN symptoms during CBTs, and vice versa. These findings may have critical implications for treatment planning and implementation.

An exploratory investigation of predictors of outcome in face‐to‐face and online cognitive‐behavioural therapy for bulimia nervosa

Cognitive-behavioural therapy (CBT) delivered face-to-face and via the internet reduces bulimia nervosa (BN) symptoms. However, our empirical understanding of factors affecting patient outcomes is limited. Using data from a randomised, controlled trial comparing internet-based (CBT4BN, n=78) with face-to-face (CBTF2F, n=71) group CBT (97% female, M=28 years), we examined general treatment (across conditions) and modality-specific predictors of end-treatment and 1-year outcomes (abstinence, binge-eating frequency, purging frequency). Improved eating disorder-related quality of life (EDQOL) during treatment and follow-up predicted abstinence at end-treatment and 1-year assessments. Improved EDQOL, disordered eating cognitions, and anxiety symptoms predicted less frequent binge eating and purging. Previous CBT and being employed predicted more frequent binge eating and purging at both assessments. Higher self-transcendence and self-directedness predicted less frequent binge eating. More severe binge eating and purging at baseline and end-treatment predicted more frequent binge eating and purging at subsequent assessments. Improved EDQOL was more strongly associated with positive outcome in CBT4BN; improved depressive symptoms and health-related QOL predicted positive outcome in CBT4BN but not CBTF2F. Symptom improvement and certain character traits predicted positive outcome, whereas more severe presentation and prior CBT experience predicted poorer outcome. Consideration of intreatment symptom improvement may facilitate care recommendations, particularly for internet-based modalities.

A closer look at homework compliance in behavior therapy for bulimia nervosa: does homework compliance in between-session period prospectively predict session-by-session change in bulimia symptoms?

ABSTRACT Introduction: Homework assignments are considered key components of behavioral treatments for bulimia nervosa (BN), but little is known about whether homework compliance predicts BN symptom improvement. The present study is the first to examine whether session-by-session change in homework compliance predicts session-by-session changes in BN symptoms during behavioral treatment.Method: Patients with BN-spectrum eating disorders (n = 42) received 20 sessions of behavioral treatment. Each session, their clinicians completed surveys assessing compliance with self-monitoring, behavioral, and written homework assignments and BN symptom frequency during the previous week.Results: Significant between-persons effects of self-monitoring and behavioral homework compliance were identified, such that patients with greater compliance in the past week experienced greater reductions in binge eating and purging the following week. There were significant within-persons effects of self-monitoring compliance on binge eating and behavioral homework compliance on restrictive eating, binge eating, and purging, such that greater than one’s usual compliance predicted greater improvements in BN symptoms the following week. No significant effects of written homework compliance were identified.Conclusion: Compliance with self-monitoring and behavioral homework predict improvements in BN symptoms during behavioral treatment. These findings reinforce the importance of self-monitoring and behavioral homework compliance as drivers of change during treatment for BN.

Prevalence and early risk factors for bulimia nervosa symptoms in inner-city youth: gender and ethnicity perspectives

BackgroundResearch on risk factors associated with bulimia nervosa symptoms (BN) in ethnic minorities has been limited. This study adds to the existing literature by providing the ethnicity- and gender-specific prevalence of BN in US inner-city youth and by exploring the longitudinal associations between a clinical level of BN and early risk factors assessed one year previously.MethodsThe study was conducted on a representative sample of predominantly ethnic minority youth (N = 2794; 54.1% female; age 11–16 years old (M(SD) = 12.77(1.29)); 60.0% African-American, 26.1% Hispanic American, 13.9% White). Self-reported information was obtained on BN and early risk factors (e.g., depressive and anxiety symptoms, posttraumatic stress, somatic complaints). Multivariate analysis of covariance was used to examine the longitudinal associations.ResultsThe 3-month BN prevalence was higher in girls (5.1%) than in boys (2.3%) (ratio 2.22:1). Significant differences in BN rates were found between White and African American students (higher in Whites), whereas Hispanic-Americans did not differ significantly from either group. Individuals with BN had significantly higher levels of early risk factors one year prior.ConclusionsTimely recognition of BN and associated early risk factors is important for early prevention and intervention strategies.

Emotional reactivity to binge food and erotic cues in women with bulimia nervosa symptoms

BackgroundStudies on food cue reactivity have documented that altered responses to high-calorie food are associated with bulimic symptomatology, however, alterations in sexual motivations and behaviors are also associated clinical features in this population, which justify their inclusion as a research target. Here, we study responses to erotic cues—alongside food, neutral and aversive cues—to gain an understanding of specificity to food versus a generalized sensitivity to primary reinforcers.MethodsWe recorded peripheral psychophysiological indices –the startle reflex, zygomaticus, and corrugator responses—and self-reported emotional responses (valence, arousal, and dominance) in 75 women completing the Bulimia Test-Revised (BULIT-R). Multiple regression analysis tested whether BULIT-R symptoms were predicted by self-reported and psychophysiological responses to food versus neutral and erotic versus neutral images.ResultsThe results showed that individuals with higher bulimic symptoms were characterized by potentiated eye blink startle response during binge food (vs. neutral images) and more positive valence ratings during erotic (vs. neutral) cues.ConclusionsThe results highlight the negative emotional reactivity of individuals with elevated bulimic symptoms toward food cues, which could be related to the risk of progression to full bulimia nervosa and thereby addressed in prevention efforts. Results also point to the potential role of reactivity to erotic content, at least on a subjective level. Theoretical models of eating disorders should widen their conceptual scope to consider reactivity to a broader spectrum of primary reinforcers, which would have implications for cue exposure-based treatments.Plain English summaryWe examined appetitive and aversive cue responses in college women to investigate how bulimic symptoms relate to primary reinforcers such as food and erotic images. We recorded peripheral psychophysiological indices (the startle reflex, zygomaticus, and corrugator responses) and self-reported emotional responses (valence, arousal, and dominance) in 75 college women that were presented with the Spanish version of the Bulimia Test-Revised. The results showed that bulimic symptoms increase both psychophysiological defensiveness toward food cues and subjective pleasure toward erotic cues. The findings suggest a generalized sensitivity to primary reinforcers in the presence of bulimic symptoms, and emphasize the relevance of adopting a wider framework in research and treatment on bulimia nervosa.

The presence of migraine symptoms was associated with a higher likelihood to present eating disorders symptoms among teenage students.

To investigate the association between migraine and signs and symptoms of eating disorders among teenagers. And as secondary objectives: to investigate the prevalence of eating disorders signs and symptoms and to identify the prevalence of migraine among teenagers. Cross-sectional study was carried out in public schools which included adolescents aged 11-18years, of both sexes. For eating disorders evaluation two self-reported questionnaires were used: Eating Attitudes Test-26 (EAT-26) and The Bulimic Investigatory Test of Edinburg (BITE). The presence and characterization of headache were verified following the International Classification of Headache Disorders (ICHD-II). 607 adolescents (388 females) with mean age of 13.9years (95% CI: 13.7; 14) were included. The eating disorders symptoms based on EAT-26 (p = 0.041) and the bulimia nervosa symptoms (p = 0.014) evaluation were more prevalent among teenagers with migraine compared with non-migraine. Also, in multivariate analysis, the adjusted odds ratio (OR) to present bulimia nervosa symptoms is 1.85 times higher among females than males. And, the adjusted OR to present bulimia nervosa symptoms among teenagers with migraine is 1.51 times (OR) higher than among non-migraine. The presence of migraine symptoms were associated with a higher likelihood to present eating disorders symptoms among teenagers, especially in females, that was associated with a 1.85-fold increase in the risk to present bulimia nervosa symptoms.

Feasibility, Acceptability, and Preliminary Target Engagement of a Healthy Physical Activity Promotion Intervention for Bulimia Nervosa: Development and Evaluation via Case Series Design

Bulimia nervosa (BN) is characterized by a pattern of binge eating and compensatory behaviors as well as an overemphasis on body weight and shape in self-evaluation. Although cognitive behavioral therapy (CBT) is efficacious, recent reviews suggest that only 30% of patients reach abstinence at posttreatment. One potential reason for these poor outcomes is that CBT fails to adequately reduce elevated negative affect (NA) and shape and weight concern, which have been shown to be correlated with poorer treatment outcomes in BN. Therefore, novel treatment components that focus on improving NA and shape and weight concern are needed in order to enhance outcomes. Promoting physical activity (PA) is a promising avenue through which to reduce NA and improve body image in healthy individuals, other clinical populations (e.g., individuals with depression or anxiety), and individuals with eating disorders. While prescribing PA for individuals with BN has been controversial (due to concerns that exercise maybe be used to compensate for binge episodes or become driven or compulsive), this approach may have many benefits, including promoting healthy lifetime exercise habits that reduce likelihood of relapse through the improvement of emotion regulation skills and weight regulation.Given the promise of PA for targeting key maintenance factors of BN, we developed a 12-session healthy PA promotion intervention for BN and tested initial feasibility, acceptability, and preliminary target engagement in an iterative case series design (n = 3). The treatment provided cognitive-behavioral skills designed to identify, practice, and achieve behavioral goals while asking patients to engage in up to 150 minutes of moderate-to-vigorous PA per week, which was preplanned during each session with the client’s therapist.Results suggested that the healthy PA promotion intervention was both feasible and acceptable to deliver. In addition, the intervention resulted in a clinically significant decrease in BN symptom frequency in each participant. Further, participants showed clinically significant decreases in NA and shape and weight concern.The current study demonstrates that healthy PA interventions can have beneficial effects on BN symptoms, NA, and shape and weight concern. However, due to the small sample size, conclusions must be treated with caution. Future research should investigate additional approaches for promoting healthy PA and include a larger sample in order to further test initial efficacy of this treatment approach.

A Clinician-Controlled Just-in-time Adaptive Intervention System (CBT+) Designed to Promote Acquisition and Utilization of Cognitive Behavioral Therapy Skills in Bulimia Nervosa: Development and Preliminary Evaluation Study.

BackgroundCognitive behavioral therapy (CBT) for bulimia nervosa (BN) is most effective when patients demonstrate adequate skill utilization (ie, the frequency with which a patient practices or uses therapeutic skills) and skill acquisition (ie, the ability to successfully perform a skill learned in treatment). However, rates of utilization and acquisition of key treatment skills (eg, regular eating, urge management skills, and mood management skills) by the end of the treatment are frequently low; as a result, outcomes from CBT for BN are affected. Just-in-time adaptive interventions (JITAIs) may improve skill acquisition and utilization by delivering real-time interventions during algorithm-identified opportunities for skill practice.ObjectiveIn this manuscript, we describe a newly developed JITAI system called CBT+ that is designed to facilitate the acquisition and utilization of CBT for BN treatment skills when used as a treatment augmentation. We also present feasibility, acceptability, and preliminary outcomes data from a small proof-of-concept pilot trial (n=5 patients and n=3 clinicians) designed to identify opportunities for iterative development of CBT+ ahead of a larger ongoing randomized controlled trial.MethodsA total of 5 individuals with BN received 16 sessions of outpatient CBT for BN while using the CBT+ app. Data were collected from patients and clinicians to evaluate the feasibility (eg, app use and user adherence), acceptability (eg, qualitative patient and clinician feedback, including usefulness ratings of CBT+ on a 6-point Likert scale ranging from 1=extremely useless to 6=extremely useful), and preliminary outcomes (eg, improvements in skill utilization and acquisition and BN symptoms) of the CBT+ system.ResultsPatients reported that CBT+ was a relatively low burden (eg, quick and easy-to-use self-monitoring interface), and adherence to in-app self-monitoring was high (mean entries per day 3.13, SD 1.03). JITAIs were perceived as useful by both patients (median rating 5/6) and clinicians (median rating 5/6) for encouraging the use of CBT skills. Large improvements in CBT skills and clinically significant reductions in BN symptoms were observed post treatment. Although preliminary findings indicated that the CBT+ system was acceptable to most patients and clinicians, the overall study dropout was relatively high (ie, 2/5, 40% patients), which could indicate some moderate concerns regarding feasibility.ConclusionsCBT+, the first-ever JITAI system designed to facilitate the acquisition and utilization of CBT for BN treatment skills when used as a treatment augmentation, was shown to be feasible and acceptable. The results indicate that the CBT+ system should be subjected to more rigorous evaluations with larger samples and should be considered for wider implementation if found effective. Areas for iterative improvement of the CBT+ system ahead of a randomized controlled trial are also discussed.

A two-week daily diary study examining the association between daily self-compassion and symptoms of bulimia nervosa.

Individuals with symptoms of bulimia nervosa (BN) are more likely to binge and purge on days of greater negative affect. Given that self-compassion helps individuals cope more adaptively with distress, the present study examined the contribution of daily fluctuations in self-compassion to eating disorder symptoms in women who endorse symptoms of BN. The directionality of these associations was also examined. For 2 weeks, 124 women who met the DSM-5 criteria for BN completed nightly measures of their daily eating pathology and self-compassion. Self-compassion levels varied almost as much within a person from day-to-day as between-persons (i.e., from one person to the next). Multilevel modeling revealed that within persons, higher daily levels of self-compassion were associated with a reduced probability of both binge eating and inappropriate compensation, and lower levels of dietary restraint and clinical impairment. Secondary analyses revealed that these variables mutually influenced one another within but not across days. Between persons, higher mean levels of self-compassion over the 2 weeks were associated with less dietary restraint and clinical impairment but were unrelated to binge eating and compensatory behaviors. For women who report symptoms consistent with BN, responding to daily distress with greater self-compassion than usual may attenuate the psychosocial and behavioral symptoms of their eating disorder. Similarly, days of reduced eating pathology may facilitate self-compassion. Future research using experimental paradigms and ecological momentary assessments may shed further light on the ways in which self-compassion and eating pathology relate to one another in this population.

Longitudinal associations of trauma exposure with disordered eating: Lessons from the Great Smoky Mountains Study

ABSTRACT Disordered eating is prevalent among trauma survivors, yet little is known about mechanisms underlying this relation. We explored cross-sectional and longitudinal associations of trauma exposure and posttraumatic stress disorder symptoms (PTSD) with disordered eating among 1,420 community-based youth participating in the Great Smoky Mountain Study. Participants were interviewed about trauma exposure, PTSD symptoms, and disordered eating at regular intervals throughout childhood, adolescence, and early adulthood. Our findings confirmed associations of all forms of trauma exposure (violent, sexual, and other) with disordered eating symptoms in childhood and adulthood, although the pattern of results varied by disordered eating symptom and trauma exposure type. Only non-sexual, non-violent trauma exposure in childhood had significant associations with any disordered eating symptoms in adulthood. Within childhood, trauma exposures but not PTSD symptoms showed significant longitudinal associations with bulimia nervosa symptoms and sustained appetite changes and preoccupation with eating. In adulthood, PTSD symptoms but not trauma exposures showed significant longitudinal associations only with bulimia nervosa symptoms. The association of specific PTSD clusters on bulimia nervosa symptoms was significant for reexperiencing, whereas hyperarousal symptoms trended toward significance. The impact of trauma exposures on disordered eating may vary by developmental period.

The connection between childhood maltreatment and eating disorder psychopathology: a network analysis study in people with bulimia nervosa and with binge eating disorder

PurposeChildhood maltreatment (CM) experiences are associated with heightened risk of Eating disorders (EDs). The psychopathological pathways promoting this association in people with Bulimia nervosa (BN) and in those with Binge eating disorder (BED) are under-investigated.MethodsOne hundred and eighty-one people with BN and 144 with BED filled in the Eating Disorder Inventory-2, to measure ED psychopathology, and the Childhood Trauma Questionnaire, to assess their early traumatic experiences. Network analysis was conducted to investigate the interplay between those variables. The shortest pathways function was employed to investigate the shortest out of all routes conveying the association between CM and ED-specific symptoms.ResultsIn both people with BN and with BED, all CM types were connected to the ED psychopathology through the emotional abuse node. The association between emotional abuse and ED-specific symptoms (bulimia and body dissatisfaction) differed in the two groups: in people with BN, it included ineffectiveness, while in people with BED, it involved impulsivity. Interoceptive awareness, an indirect measure of emotion regulation, was included in these pathways in both groups.ConclusionIn the light of literature showing that emotional abuse has a connecting role between CM and ED psychopathology also in anorexia nervosa, the present findings support the idea that emotional abuse conveys such association in all the main ED diagnoses. Ineffectiveness and impulsivity may represent the specific psychopathological dimensions connected to emotional abuse and promoting the maintenance of ED-specific symptoms in BN and in BED, respectively. These findings are worth of attention by clinicians.Level of evidenceLevel III: evidence obtained from well-designed cohort or case–control analytic studies

Exploring the role of feeling fat in individuals categorized with bulimia nervosa, binge-eating disorder and overweight/obesity.

Despite featuring in prominent theoretical models, the role of "feeling fat" in certain eating and weight disorder presentations remains poorly understood. This study compared levels of feeling fat between people categorized with referable bulimia nervosa (BN) symptoms, binge-eating disorder (BED) symptoms, and overweight/obesity, and examined the unique associations of feeling fat on measures of eating pathology and functional impairment within each of these subgroups. Data were analyzed from 977 participants who met criteria referable to BN symptoms (n = 419), BED symptoms (n = 346), or overweight/obesity without ED psychopathology (n = 212) based on self-report symptom frequency. Analysis of variance revealed that feeling fat levels were highest in the referable BN group, followed by the referable BED group, and then the overweight/obese subgroup. Multiple regressions revealed that feeling fat contributed additional variance to functional impairment and key cognitive (e.g., eating concerns) and behavioural (e.g., dietary restraint) symptoms only among those who met criteria referable to BN. Overall, findings suggest that the experience of feeling fat may be an important component of body image particularly among individuals with BN-type symptoms. Present findings may also have implications for the assessment and treatment of feeling fat among different eating and weight disorder presentations. Cross-sectional descriptive study, Level V.

Childhood Maltreatment and Eating Disorders: A Prospective Investigation

To determine whether childhood maltreatment is a risk factor for two eating disorders (anorexia nervosa and bulimia nervosa) using objective and subjective case definitions. Using a prospective cohorts design, children with documented cases of physical abuse, sexual abuse, and neglect (ages 0-11) from 1967 to 1971 in a Midwestern metropolitan county area were matched on age, race, sex, and approximate family socioeconomic status with non-maltreated children. Both groups were followed up. Retrospective self-reports about childhood maltreatment were collected at age 29. DSM-IV anorexia nervosa (AN) and bulimia nervosa (BN) disorders were assessed at age 41 (N = 807). Logistic and linear regression results are reported. Using documented cases, childhood maltreatment was not a significant risk factor for AN or BN diagnoses or symptoms in adulthood. However, adults who retrospectively reported any maltreatment and physical and sexual abuse reported significantly more symptoms of AN than those who did not. The prediction that childhood maltreatment is a risk factor for anorexia nervosa and bulimia nervosa was partially supported in this longitudinal study. While misattribution of cases might have occurred, these results suggest that researchers and clinicians should use caution in drawing inferences about these relationships and designing interventions.

Automatic attentional bias toward high-calorie food cues and body shape concerns in individuals with a high level of weight suppression: Preliminary findings

This study aimed to investigate differences in attentional processes in response to food cues and body shape concerns according to an individual's level of weight suppression. Among 470 women in their 20s, nonobese participants (body mass index [BMI] <25 kg/m2) were divided into two groups according to weight history. If the difference between their highest weight ever and current weight was greater than 10%, they were assigned to the high level of weight suppression (H-WS) group (n = 24); if it was less than 5%, they were assigned to the low level of weight suppression (L-WS) group (n = 29). Self-reported body shape concerns and bulimia nervosa symptoms were assessed. Visual attentional processes were recorded using an eye tracker while participants completed a free-viewing task composed of pairs of high- and low-calorie food cues. After controlling for current BMI, the H-WS group reported higher body shape concerns and higher levels of bulimia nervosa symptoms than did the L-WS group. In the free-viewing task, after controlling for current BMI, body shape concerns, and bulimia nervosa symptoms, the H-WS group had a significantly longer dwell time for high-calorie compared with low-calorie food cues than did the L-WS group, and this difference was observed for the first 1000 ms. Compared with individuals with low weight suppression, the vulnerability to bulimia nervosa symptoms observed in individuals with high weight suppression may be associated with a higher automatic approach tendency toward high-calorie foods after adjusting for body shape concerns.

Anorexia nervosa: A literature review

Introduction: Anorexia nervosa is a food intake disorder characterized by acute weight loss that it could cause severe psychosomatic problems. Purpose: To present the data and information as well as the treatment related to Anorexia nervosa. Materials and methods: The study material consisted of reviewed articles on the topic found in Greek and globally accepted electronic databases, Pubmed, Scopus, Medline, Google Scholar, regarding the effects of Anorexia nervosa on health and its treatment. Results: Initial symptoms of Anorexia nervosa and Bulimia Nervosa may be characterised by body-related negative interpretation bias, distorted body image and pronounced body dissatisfaction. Anorexic patients refuse to eat with their family or in public places. They lose weight by drastically reducing their total food intake, with a disproportionate reduction in the amount of meals containing carbohydrates and fats. The term Anorexia is unfortunate, because a decrease in appetite does not occur. Patients are constantly hungry and they are constantly thinking about food, but they refuse it. An indication of their way of thinking is that they often collect recipes or prepare complex meals for others. Conclusions: Anorexia nervosa is a disease that connects the physical with the mental dimension of health. A person's disharmonious relationship with oneself, which may have its roots in a dysfunctional family context or in a demanding and competitive social environment, finds the way to be manifested through the individual's reflection on food.

Prospective associations between childhood social communication processes and adolescent eating disorder symptoms in an epidemiological sample.

Deficits in social cognition and communication, the processes associated with human social behavior and interaction, have been described in individuals with eating disorder psychopathology. The current study examined whether social communication characteristics present in middle childhood (ages 8-14) were associated with eating disorder behaviors, cognitions, and diagnoses across adolescence (ages 14-18) in a large, population-based sample. Participants (N = 4864) were children enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based, prospective study of women and their children. Regression methods tested prospective associations between social functioning using a facial emotion recognition task and parentally reported social communication symptoms (or difficulties), measured by the Social Communication Disorder Checklist (SCDC), with eating disorder symptoms and diagnoses. Misattribution of faces as sad or angry at age 8.5 was associated with purging and anorexia nervosa diagnosis at age 14, respectively, among girls. Furthermore, autistic-like social communication difficulties during middle childhood were associated with bulimia nervosa symptoms during adolescence among both girls and boys. Results did not support global associations between measured social communication deficits and eating disorder risk in this sample, but specific difficulties with facial emotion recognition and social communication may enhance the risk for disordered eating behaviors.

The relationship of the UPPS model of impulsivity on bulimic symptoms and non-suicidal self-injury in transgender youth

ObjectiveThis brief report examined the relationship of negative urgency (the tendency to act rashly in response to negative emotional states), (lack of) perseverance, (lack of) premeditation, and sensation seeking in association with non-suicidal self-injury (NSSI) and symptoms of bulimia nervosa (BN) in a sample of treatment-seeking transgender (TG) youth. MethodEighty-six TG youth with a mean age of 17 (sd = 3.2) agreed to participate in the study. The majority of our sample identified as TG male (n = 60) with 20 participants identifying as TG female and 6 identifying as non-binary. The racial ethnic breakdown of our sample was 8.2% Black, 8.2% Multi-racial, 1.2% Native American, and 82.4% White. Over ¼ of our sample endorsed at least one episode of objective binge eating in the last 28 days and 62% endorsed a history of NSSI. ResultsNegative urgency was significantly associated with the odds of NSSI, objective binge eating, and general eating disorder symptoms. Lack of premeditation was significantly related to the odds of NSSI only. No other factors were significantly associated with NSSI or symptoms of BN. ConclusionsNegative urgency appears to be an important personality construct in understanding increased risk for NSSI and BN symptoms in transgender youth.

Impulsivity and anxiety-related dimensions in adults with bulimic-spectrum disorders differentially relate to eating disordered behaviors

While facets of both anxiety and impulsivity appear central to the development and maintenance of bulimia nervosa (BN), specific BN behaviors may be propagated by differing profiles of risk. The current study examined associations between dimensions of anxiety and impulsivity and BN symptoms (binge eating, vomiting, laxative misuse, driven exercise), both in terms of the presence of such behaviors and their frequency. Two hundred and four women (Mage = 25.7 years) who met DSM-IV criteria for full or subthreshold BN completed self-report measures of perfectionism (Frost Multidimensional Perfectionism Scale), anxiety (Spielberger Trait Anxiety Inventory), impulsivity (Barratt Impulsiveness Scale–11; Impulsive Behavior Scale), eating disordered behaviors (Eating Disorder Examination – Questionnaire), and associated psychiatric symptoms (Michigan Assessment Screening Test/Alcohol-Drug; Maudsley Obsessive-Compulsive Inventory). Factor analysis revealed multidimensional impulsive and anxiety-related traits (5 anxiety-related factors; 7 impulsivity-related factors). In zero-sensitive regression models, different facets of impulsivity evidenced association with the presence of binge eating (risk taking), laxative misuse (impulsive spending), and fasting (difficulty concentrating), along with the frequency of vomiting (long-term planning difficulties). In contrast, anxiety-related dimensions were only associated with driven exercise (high standards) and fasting (concern over mistakes, high standards, parental expectations). Overall, impulsive and anxiety-related factors and symptoms showed distinct associations with specific eating disorder behaviors, even among those with the same diagnosis.

Benefits of yoga in the treatment of eating disorders: Results of a randomized controlled trial

ABSTRACT Yoga has begun to be incorporated into the treatment of eating disorders despite limited empirical support for this practice. The purpose of this study was to investigate the efficacy of incorporating Yoga into the treatment of eating disorders. This preliminary randomized controlled trial investigated the benefits of participating in an eight-week Kripalu Yoga program for 53 women with symptoms of bulimia nervosa and binge eating disorder. Compared to waitlist controls, Yoga participants experienced decreases in binge eating frequency, emotional regulation difficulties and self-criticism, and increases in self-compassion. Yoga participants also experienced increases in state mindfulness skills across the eight weeks of the Yoga program. While these results are encouraging and suggest Yoga may have a valuable role to play in the treatment of eating disorders, it is important to stress their tentative nature. Further research, adopting a more rigorous design, is needed to address the limitations of the present study and expand on these findings.
