Profiling decision-making mechanisms in binge eating disorder.

ObjectiveThis review aimed to examine the validity of self‐report screening questionnaires for identifying eating disorder (ED) risk in adults and adolescents with overweight/obesity.MethodFive databases were searched from inception to September 2020 for studies assessing validation of self‐report ED screening questionnaires against diagnostic interviews in adolescents and adults with overweight/obesity. The review was registered with PROSPERO (https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=220013).ResultsTwenty‐seven papers examining 15 questionnaires were included. Most studies validated questionnaires for adults (22 of 27 studies), and most questionnaires (12 of 15) screened for binge eating or binge‐eating disorder (BED). The Eating Disorder Examination Questionnaire (sensitivity = .16–.88, specificity = .62–1.0) and Questionnaire on Eating and Weight Patterns (sensitivity = .07–1.0, specificity = .0–1.0) were most frequently validated (six studies each). Five studies of three questionnaires were in adolescents, with the Adolescent Binge‐Eating Disorder Questionnaire having highest sensitivity (1.0) but lower specificity (.27). Questionnaires designed to screen for BED generally had higher diagnostic accuracy than those screening for EDs in general.DiscussionQuestionnaires have been well validated to identify BED in adults with overweight/obesity. Validated screening tools to identify other EDs in adults and any ED in adolescents with overweight/obesity are lacking. Thus, clinical assessment should inform the identification of patients with co‐morbid EDs and overweight/obesity.Public SignificanceIndividuals with overweight/obesity are at increased risk of EDs. This review highlights literature gaps regarding screening for ED risk in this vulnerable group. This work presents possibilities for improving care of individuals with overweight/obesity by reinventing ED screening tools to be better suited to diverse populations.

Excessive energy intake likely favors metabolic dysfunction in patients with schizophrenia and may be, in part, the consequence of antipsychotic treatments. However, previous studies on the prevalence of bulimia and binge eating symptoms in antipsychotic-treated patients are contradictory and not sufficiently informative. The prevalence of bulimia nervosa, binge eating disorder, and subsyndromal binge eating disorder was studied using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria in 156 patients with schizophrenia or schizoaffective disorder treated with antipsychotic monotherapy. The effects of different antipsychotics were compared. The prevalence of full syndromal binge eating disorder was 4.4% and that of subsyndromal binge eating disorder was 18.7% in patients (23.1% for binge eating spectrum disorder), and there were no cases of bulimia nervosa. Compared with the whole sample, binge eating spectrum disorders were significantly more prevalent in clozapine- and olanzapine-treated patients. Comparisons of patients having undergone treatment for 2 years or less with patients treated for more than 2 years showed that binge eating spectrum disorders decrease significantly over time, the difference being significant in clozapine- and olanzapine-treated patients. Night eating, simply assessed by a single question, showed a prevalence of 30% and was more prevalent in women treated with clozapine and olanzapine, with no significant change over time. Binge eating disorders should be considered as important factors involved in the development of weight gain and metabolic syndrome in antipsychotic-treated patients with schizophrenia. The difficulty to reliably assess binge eating spectrum disorders in patients with psychosis is highlighted.

IntroductionObesity is a major public health problem and some developed countries have declared it ‘the modern day epidemic’. One of the major eating disorders that leads to obesity is BED, which involves consuming large quantities of high carbohydrate food. Studying the factors that cause and contribute to BED can help tackle this major health hazard and alleviate a huge burden on the nationalized health service.ObjectivesTo determine the frequency of Binge Eating Disorder (BED) among obese adults, and to study its relationship to depression, anxiety, life stressors, personality and self esteem.MethodsThe sample was a randomised sample of clinically obese individuals, body mass index (BMI) of 30 and above. The sample was collected from two sites; Nutrition Clinic in Student’s Hospital, Cairo University and a Private Nutrition Centre. 250 cases were recruited over one year. All patients were subjected to a clinical interview derived from Kasr El Aini sheet , and measurement of Waist- Hip Ratio. Assessment of depression and anxiety was through Beck Depression Inventory , Hamilton Depression Rating Scale and Taylor Manifest Anxiety Scale(TMAS). Other tools used were the Eysenck’s Personality Inventory, Eating Disorder Inventory -2.ResultsBED among obese adults was 48%; 83 % of them had drive for thinness, 25% were bulimics, 45 % had ineffectiveness feeling. Also 83 % had body dissatisfaction, 8% were perfectionism seeking, 43 % showed interpersonal distrust and 25% presented maturity fears. Impulsivity was scored high in 25% , 66.6%had social insecurity and 77% had severe Extraversion. All were statistically significant. On the other hand there were no statistical significant difference between obese adults with BED and those without on TMAS. Half percent of participants with BED and 34.6 percent of participant without BED had moderate level of anxiety. In addition , there were no significant difference between obese participants with BED and those without BED according to BDI. However, 83.3% of obese cases with BED while 60 % for those without BED had manifest depression ranging from mild to severe depression.ConclusionsObese adults with BED have more drive for thinness, body dissatisfaction, feeling of ineffectiveness, perfectionism seeking, interpersonal distrust, maturity fears and social insecurity than non BED. Extraversion and Neuroticism are also more among BED. There were no significance different between both group in relation to Anxiety and Depression.Disclosure of InterestNone Declared

In the historical development of psychiatric nosology, as in the rest of medicine, more severe disorders tend to be recognized before disorders with milder symptom profiles. Thus, psychiatric classifications recognized schizophrenia and melancholia before schizotypal personality disorder and dysthymia. So, too, with the classification of eating disorders; anorexia nervosa, which may result in death, was recognized many years before bulimia nervosa. The most recent addition to the psychiatric classification of eating disorders is “binge eating disorder.” The diagnosis of binge eating disorder is given to the many obese individuals who are distressed by recurrent binge eating, yet do not regularly engage in the compensatory behavior (e.g., vomiting or use of laxatives) that is seen in individuals with bulimia nervosa. Although binge eating disorder is not an official DSM-IV diagnosis, a variety of studies support its validity (1–4). A description of the disorder and its diagnostic criteria appear in DSM-IV Appendix B, titled “Criteria Sets and Axes Provided for Further Study.” Binge eating disorder is common among study groups drawn from weight-control programs (15%–50%), which show women are approximately 1.5 times more likely to have the disorder than men. In nonpatient community samples, a prevalence rate of 1%–4% has been reported (1, 3). Typically, the disorder begins in late adolescence or in the early 20s, often after weight loss from severe dieting. Common associated features include marked fluctuations in weight over time and a history of depression, anxiety, low self-esteem, somatic concern, and interpersonal sensitivity. Along with the recognition of binge eating disorder and its clinical features, there has been increasing interest in developing effective treatments for the disorder. Several studies have examined the relative efficacy of psychotherapeutic and psychopharmacological approaches (5). This case conference illustrates some of the challenges and rewards involved in the treatment of a patient with binge eating disorder.

Although the cross-cultural prevalence of anorexia and bulimia nervosa has been investigated in multiple studies, little is known about the prevalence and correlates of binge eating and binge eating disorder (BED) cross-culturally. No published studies to date have explored BED in small-scale, indigenous, or developing societies. The current study investigated the prevalence and correlates of binge eating in a community sample of Fijian women living in rural Fiji. Fifty ethnic Fijian women completed a self-report measure developed for this study on dieting and attitudes toward body shape and change, a Nadroga-language questionnaire on body image, and the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R). Their height and weight were also measured. Patterns of dieting, high body mass index (BMI), and attitudes toward eating and body image were compared between women with and without a history of binge eating. Ten percent of respondents reported at least weekly episodes of binge eating during the past 6 months and 4% endorsed symptoms consistent with BED. Binge eating in this sample was associated significantly with a BMI value above 35, a history of dieting, and a high concern with body shape. Binge eating was not associated with several markers of acculturation in this sample, although it was associated with a key, nontraditionally Fijian (i.e., acculturated) attitude toward the body. Binge eating occurred in a social context with traditions concerning weight and diet widely disparate from Western populations. However, correlates of binge eating in this sample suggest that nontraditional Fijian attitudes toward weight and body shape play a contributory role.

There is increasing evidence that patients who have problems with binge eating (BE) or BE disorder (BED) are quite common among the severely obese, including bariatric surgery candidates. The literature suggests that in many cases such eating behaviours improve after bariatric surgery, although this is not uniformly true. The current paper reviews the data on the development of BE, BED and loss of control (LOC) eating after bariatric surgery and the impact of these problems on long-term weight outcome. A search was made of various databases regarding evidence of BE, BED and LOC eating post-operatively in bariatric surgery patients. The data extracted from the literature suggests that 15 research studies have now examined this question. Fourteen of the available 15 studies suggest that the development of problems with BE, BED or LOC eating post-bariatric surgery is associated with less weight loss and/or more weight regain post-bariatric surgery. These data suggests that it is important to identify individuals at high risk for these problems, to follow them post-operatively, and, if appropriate interventions can be developed if such behaviours occur in order to maximize weight loss outcomes.

Few studies have assessed the association between attention-deficit hyperactivity disorder (ADHD) and eating disorders (ED) separately in men and women, especially in representative samples. Using data from the National Comorbidity Survey Replication, lifetime and past 12-month prevalence of Diagnostic and Statistical Manual of Mental Disorders IV, ADHD was compared in men and women with and without diagnoses of Diagnostic and Statistical Manual of Mental Disorders IV ED and any binge eating (BE) using logistic regression models adjusted for gender and age. In both sexes, those with lifetime and past 12-month BE and binge eating disorder had significantly higher prevalence of ADHD than those without BE and binge eating disorder, respectively. Women with lifetime and past 12-month bulimia nervosa and lifetime anorexia nervosa also had significantly higher prevalence of ADHD compared with women without these diagnoses. Given that ADHD invariably began earlier than the ED, ADHD may be an important risk factor for subsequent BE and related ED, and there may be opportunities for intervention among youth with ADHD.

BackgroundBinge eating disorder (BED) represents a distinct eating disorder diagnosis. Current approaches assume increased impulsivity to be one factor leading to binge eating and weight gain. We used eye tracking to investigate both components of impulsivity, namely reward sensitivity and rash-spontaneous behaviour towards food in BED for the first time.MethodsOverweight and obese people with BED (BED+; n = 25), without BED (BED−; n = 26) and healthy normal-weight controls (NWC; n = 25) performed a free exploration paradigm measuring reward sensitivity (experiment 1) and a modified antisaccade paradigm measuring disinhibited, rash-spontaneous behaviour (experiment 2) using food and nonfood stimuli. Additionally, trait impulsivity was assessed.ResultsIn experiment 1, all participants located their initial fixations more often on food stimuli and BED+ participants gazed longer on food stimuli in comparison with BED− and NWC participants. In experiment 2, BED+ participants had more difficulties inhibiting saccades towards food and nonfood stimuli compared with both other groups in first saccades, and especially towards food stimuli in second saccades and concerning sequences of first and second saccades. BED− participants did not differ significantly from NWC participants in both experiments. Additionally, eye tracking performance was associated with self-reported reward responsiveness and self-control.ConclusionsAccording to these results, food-related reward sensitivity and rash-spontaneous behaviour, as the two components of impulsivity, are increased in BED in comparison with weight-matched and normal-weight controls. This indicates that BED represents a neurobehavioural phenotype of obesity that is characterised by increased impulsivity. Interventions for BED should target these special needs of affected patients.

Binge Eating Disorder (BED) is characterized by recurrent episodes of eating large quantities of food in a brief period. Bouts of binge are commonly associated with a lack of control on stop eating or on what or how much one is eating. The binge eating is not associated with recurrent use of inappropriate compensatory behavior as bulimia nervosa and occurs, on average, at least once a week for 3 months [1]. BED is also associate with obesity and motor inactivity [2]. Aim of this study was to estimate the effectiveness of a structured physical activity program on the Body Mass Index (BMI) in BED patients. 19 BED women were recruited for this study. The subjects were randomly assigned to two groups: Intervention Group (IG, n=10) and Control Group (CG, n=9). All participants underwent the following measurements: height and weight, to calculate BMI (kg/m²) and participated into the weekly multidisciplinary program, constituted by Cognitive Behavioral Therapy and diet. In addition, the IG carried out a structured physical activity program for 6 months. The exercise session consisted of aerobic, balance and strength activity performed in four weekly sessions of 90 minutes. At baseline and after 6 months BMI was assessed in both groups. Both groups improved their BMI for the influence of diet and changes in body composition but the IG achieved greater results probably for the effects of structured physical activity program. The combination of traditional BED treatment and physical activity seem to improve the quality of life, to increase habitual activity level and to reduce Body Mass Index in BED patients.

Binge eating disorder: What are the differences in emotion regulation, impulsivity, and eating behaviors according to weight status?

The purpose of this chapter is to review the literature on the relationship between attention-deficit-hyperactivity-disorder (ADHD) and binge eating as seen in bulimia nervosa (BN) and binge eating disorder (BED), including the shared phenomenology, genetics and treatment. The authors reviewed all the published peer reviewed literature in the past decade available through PubMed on the epidemiology, phenomenology, genetics and management of binge eating behavior, especially as it manifests in eating disorders (BN, BED), as well as in obesity and within the context of ADHD throughout the lifespan. It was found that there is a significant association between ADHD and binge eating in clinical populations. Inattentiveness and impulsivity noted in ADHD are thought to play a role in the preoccupations, urges and impulsive behaviors of those who experience binge-eating episodes. Molecular genetic studies have also identified common genes involved in dopamine transport, suggesting a shared genetic predisposition to binge eating, obesity and ADHD. Case reports on individuals with BN and ADHD suggest benefit from psychostimulant medication. In addition, other anti-ADHD medications such as atomoxetine have been used independently in trials to treat obesity and BED. Individuals with current symptoms or a past history of ADHD are at risk of having coexisting binge eating and obesity. Screening for ADHD in patients with binge-eating behaviors may identify individuals who could benefit from anti-ADHD medications. Further research may help to identify shared neurobiological mechanisms and particular risk factors, as well as to determine the efficacy and tolerability of certain medications in this population.

The evolving epidemiology and differential etiopathogenesis of eating disorders: implications for prevention and treatment.

The interpersonal model has been validated for binge eating disorder (BED), but it is not yet known if the model applies to individuals who are obese but who do not binge eat. The goal of this study was to compare the validity of the interpersonal model in those with BED versus those with obesity, and normal weight samples. Data from a sample of 93 treatment-seeking women diagnosed with BED, 186 women who were obese without BED, and 100 controls who were normal weight were examined for indirect effects of interpersonal problems on binge eating psychopathology mediated through negative affect. Findings demonstrated the mediating role of negative affect for those with BED and those who were obese without BED. Testing a reverse model suggested that the interpersonal model is specific for BED but that this model may not be specific for those without BED. This is the first study to find support for the interpersonal model in a sample of women with obesity but who do not binge. However, negative affect likely plays a more complex role in determining overeating in those with obesity but who do not binge.

To determine the effects of binge eating disorder (BED) on weight loss and maintenance in women undergoing treatment for obesity, we studied the weight changes of 38 women (body mass index > 30 kg/m2), 21 of whom met proposed criteria for BED and 17 of whom reported few problems with binge eating, during and after a 26-week comprehensive very-low-calorie diet (VLCD) treatment program. All 17 subjects without and 16/21 subjects with BED returned for four follow-up visits over 12 months (p = 0.05). While a similar proportion of subjects with and without BED reported absolute adherence to both the modified fast and refeeding, those with BED showed a significantly different distribution in energy intake from those without BED, with fewer small and more large lapses among those who deviated from the diet (p < 0.05). There was no significant difference in mean weight loss over the 26 weeks of treatment, but subjects with BED showed significantly diminished weight loss during the middle third of treatment (p < 0.05). Black subjects, regardless of the presence of BED, lost significantly less weight during treatment than white subjects (p < 0.005). Although there was no significant difference in mean weight loss at any of the four follow-up visits between subjects with and without BED, 25% of subjects with BED had regained > 50% of their lost weight by three-month follow-up, vs. no subjects without the disorder (p < 0.05). One year after completing treatment, approximately half of BED (+) and BED (-) subjects had a good outcome, maintaining a weight loss > or = 10% of initial body weight. However, 35% of subjects with BED, and none of the subjects without BED, had a poor outcome (p < 0.05). We conclude that many individuals with BED will respond well to a medically supervised comprehensive VLCD program, attaining medically significant weight loss. However, this subgroup appears to be at risk for early major regain of lost weight and for poor outcome one year following weight-loss treatment.
