The effect of group cognitive behavior therapy on Chinese patients with anorexia nervosa: an open label trial.

J Eat Disord 2021 Sep 15;9(1):114. Epub 2021 Sep 15.

Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine, 600 South Wanping Road, Shanghai, China.

Background: The high cost of treatment for anorexia nervosa (AN) and lack of trained specialists have resulted in limited accessibility of effective treatment to patients with AN, which is particularly problematic in China. To increase the accessibility of evidence-based treatment and reduce the cost of treatment, this study aimed to explore the feasibility and efficacy of group cognitive behavior therapy (G-CBT) adapted from enhanced cognitive behavior therapy for eating disorders (CBT-E) in Chinese AN patients.

Method: A total of 78 patients with AN were assigned to G-CBT or individual outpatient treatment (IOT) and received three months of treatment for AN in each condition. Read More

A mixed-methods approach to conceptualizing friendships in anorexia nervosa.

PLoS One 2021 15;16(9):e0254110. Epub 2021 Sep 15.

Duke University Department of Psychology and Neuroscience, Durham, NC, United States of America.

Background: Individuals with anorexia nervosa have reported feelings of loneliness, social anhedonia, and interpersonal difficulties. This study sought to clarify the nature of interpersonal relationships in adults with anorexia, which may help improve existing interventions while also facilitating the attainment of something that might compete with the drive for thinness: friendships.

Methods: The present study used a mixed-methods approach to investigate friendship experiences in three groups: anorexia (n = 27), participants with a history of anorexia who are weight restored (n = 20), and healthy controls (n = 24). Read More

Acute Stress Exposure Alters Food-Related Brain Monoaminergic Profiles in a Rat Model of Anorexia.

J Nutr 2021 Sep 14. Epub 2021 Sep 14.

Interdepartmental Graduate Program in Nutritional Sciences, Iowa State University, Ames, IA, USA.

Background: Adverse life experiences are a major risk factor for anorexia nervosa (AN). Eating-provoked anxiousness associated with AN is postulated to be due to food-related exaggerated serotonin activity in the brain and imbalances of monoamine neurotransmitters.

Objectives: Using a rodent model of stress-induced hypophagia, we investigated if stress exposure augments food-related serotonin turnover and imbalances in measures of brain serotonin and dopamine activity in manners consistent with anxiousness toward food and restricted eating. Read More

Early weight gain trajectories in first episode anorexia: predictors of outcome for emerging adults in outpatient treatment.

J Eat Disord 2021 Sep 14;9(1):112. Epub 2021 Sep 14.

Department of Psychological Medicine, King's College London, Institute of Psychiatry, Psychology, and Neuroscience, 16 De Crespigny Park, London, UK.

Background: Early response to treatment has been shown to be a predictor of later clinical outcomes in eating disorders (EDs). Specifically, early weight gain trajectories in anorexia nervosa (AN) have been shown to predict higher rates of later remission in inpatient treatment. However, no study has, as of yet, examined this phenomenon within outpatient treatment of first episode cases of AN or in emerging adults. Read More

Ectodermal disturbance in development shared by anorexia and schizophrenia may reflect neurodevelopmental abnormalities.

Brain Behav 2021 Sep 12. Epub 2021 Sep 12.

Medical University of Warsaw, Warsaw, Poland.

Minor physical abnormalities (MPA) are subtle dysmorphic features of bodily structures that have little or no impact on function. Most MPA develop during the first gestational trimester and are considered as important indicators of neuroectodermal deficiencies emerging during early brain development. A higher frequency of MPA was confirmed in schizophrenia patients and their relatives, when compared to controls. Read More

Feeling imperfect and imperfectly feeling: A network analysis on perfectionism, interoceptive sensibility, and eating symptomatology in anorexia nervosa.

Eur Eat Disord Rev 2021 Sep 12. Epub 2021 Sep 12.

Department of Neuroscience "Rita Levi Montalcini", Eating Disorders Center, University of Turin, Turin, Italy.

Objective: In recent years, the network analysis (NA) methodology has been applied to identify the central features of the psychopathology of anorexia nervosa (AN) and specific connections to previously recognized vulnerabilities. However, an NA investigating both multidimensional perfectionism and interoceptive sensibility in connection to eating symptomatology is currently missing.

Method: A total of 260 individuals (139 patients with AN, 121 healthy control individuals) completed the Frost Multidimensional Perfectionism Scale, the Multidimensional Assessment of Interoceptive Awareness and the Eating Disorders Inventory-2. Read More

Prevention of eating disorders-Efficacy and cost-benefit of a school-based program ("MaiStep") in a randomized controlled trial (RCT).

Int J Eat Disord 2021 Sep 8. Epub 2021 Sep 8.

Department of Child and Adolescent Psychiatry and Psychotherapy, University Medical Center of the Johannes Gutenberg University Mainz, Mainz, Germany.

Objective: Given the severity of eating disorders, effective and easily implementable prevention programs which reduce incidence rates and in addition have health-economic benefits are essential. The majority of research on prevention programs focuses on questionnaire-based efficacy or the reduction of eating disorder symptoms while neglecting the health-economic perspective. By contrast, the present study focuses on both an efficacy analysis considering diagnostic criteria (DSM-5) and on evaluating the cost-benefit of a universal prevention program for eating disorders ("MaiStep").
