Purpose: To compare individuals with class II and III obesity with and without binge eating disorder (BED) in terms of sociodemographic characteristics, depressive symptoms, self-esteem, eating behaviors, and cognitive variables thought to be involved in the pathophysiology of the disease.
Methods: The participants were selected from volunteer patients with body mass index ≥ 35 applying to the Ondokuz Mayıs University Medical Faculty, Turkey, for bariatric surgery between 01.07.2016 and 31.05.2019. The Beck Depression Inventory (BDI), Rosenberg Self-Esteem Scale (RSES), and Eating Disorder Examination Questionnaire (EDE-Q) were administered to all participants.
Results: Binge eating disorder (BED) was determined in 95 (34%) of the 278 individuals applying for bariatric surgery. The frequency of previous psychiatric diseases was higher in the BED group than in the non-BED group. BDI, RSES, total EDE-Q, weight concern, shape concern, and eating concern EDE-Q subscale scores were also higher in the BED group. Correlation analysis revealed positive low correlation between depression scores and total EDE-Q scores and all subscales scores, with the exception of restraint. Positive low correlation was determined between decreased self-esteem and body weight and shape concern. At multivariate regression analysis, cognitive variables explained 28.6% of variance in depressive symptoms in the BED group, and 21.5% of variance in self-esteem.
Conclusion: The study results showed elevation in cognitive factors in patients with BED compared to the controls. Among these variables, eating and weight concern were shown to be associated with depressive symptoms, while eating concern was linked to self-esteem.
Level Of Evidence: Level III, case-control analytic study.

Binge eating (BE) is associated with psychological distress, functional impairment, and elevated risk of eating disorder diagnoses, and BE prevalence is increasing. Motivational and self-regulatory processes such as delay discounting may be important influences on BE; however, evidence is inconclusive, and lacks explanation of mechanisms. This study investigated how food choice motives mediate the pathway from delay discounting (DD) to BE symptomatology.

The presentation of avoidant/restrictive food intake disorder (ARFID) characterized by fear of aversive consequences of eating (fear-ARFID) has both phenomenological and mechanistic similarities to panic disorder. In this narrative review, we propose a shared model of the pathogenesis of the two disorders, centered on interoceptive sensitivity as the key maintenance mechanism. We review the evidence that fear-ARFID, which involves restrictive eating motivated by a desire to avoid aversive events (e.

Introduction: Following liver transplantation (LT), adequate nutrition is essential, as malnutrition may contribute to slower growth in pediatric patients and put patients at risk of complications following transplant. Avoidant Restrictive Food Intake Disorder (ARFID) is an eating disorder characterized by restrictive eating patterns that compromise nutrition. Patients with ARFID may have significant difficulty meeting nutritional needs due to fear of gastrointestinal distress, making it especially difficult to manage in patients following LT.

Background: Eating disorders (EDs) are among the least studied mental disorders in individuals at clinical high risk for psychosis (CHR-P). The primary aim (a) of this systematic review and meta-analysis was to identify factors predicting ED diagnoses in CHR-P individuals. The secondary aim (b) was providing a comprehensive clinical description of individuals with both CHR-P and EDs/ED-related symptoms.

Fitness clubs may be environments where abnormal eating behaviors and excessive exercise are socially accepted, potentially putting individuals at risk for disordered eating (DE). This study examined the DE risk prevalence among gym members, comparing body appreciation, exercise motivation, frequency, BMI, and age across DE risk levels, and assessed the associated factors. A sample of 232 gym members (age: 39.
