OBJECTIVE: Reduced grey (GM) and white matter (WM) volumes and increased cerebrospinal fluid (CSF) have been frequently reported in anorexia nervosa (AN), but studies focusing on cortical thickness (CT) are scarce and findings inconsistent. We conducted the first study in AN that analyzed both parameters in the same study to gain novel and comprehensive insight. METHOD: Voxel-based morphometry (VBM) analysis was performed on T1-weighted magnetic resonance images from 34 predominantly adult women with acute AN, 24 REC participants, and 41 healthy controls (HC)...

OBJECTIVE: This study examined whether patterns of eating-disorder (ED) psychopathology differed by gender across DSM-5 severity specifiers in anorexia nervosa (AN) and bulimia nervosa (BN). METHOD: We tested whether ED psychopathology differed across DSM-5 severity specifiers among 532 adults (76% female) in a residential treatment center with AN or BN. We hypothesized that severity of ED psychopathology would increase in tandem with increasing severity classifications for both males and females with AN and BN...

We present a novel case of a woman with coincident occurrence of auditory and visual hallucinations, electrolyte disturbances, chloride unresponsive alkalosis, and an eating disorder. The patient was ultimately diagnosed with Gitelman syndrome comorbid with schizophreniform disorder and avoidant restrictive food intake disorder. Eating disorders are often associated with electrolyte abnormalities which, in turn, can cause or contribute to other neuropsychiatric symptoms. At the same time, psychotic disorders can lead to food intake aversions or overconsumption of fluids with associated effects on electrolyte balance...

A stereotype exists that anorexia nervosa (AN) is a "female" disorder. As a result, men with AN may face harsher stigmatization from their peers or go undiagnosed. The shifting standards model provides a framework to explore how gender stereotypes impact perceptions of AN. Participants (N = 438) were given a vignette of a person with symptoms of AN labeled as either male or female. Assessments were experimentally manipulated according to the shifting standards perspective: participants were asked if they were concerned (or convinced) that the target had AN and then indicated the severity of behavioral symptoms (calorie reduction, pounds lost per week, and hours of exercise) needed to make them concerned (or convinced) of AN...

OBJECTIVE: People with eating disorders can have low motivation to change their eating disorder behaviors. Interventions aiming to enhance motivation to change have been increasingly advocated in their treatment. Questions remain regarding the strength of the evidence supporting the effectiveness of interventions that specifically focus on improving motivation. This review explored the evidence for improving motivation to change in eating disorders via clinical interventions. METHOD: Searches of the published and unpublished literature were conducted by searching databases (PubMed, PsychInfo, Web of Science) and trial registries (WHO ICTRP), and by contacting authors...

Individuals with disordered eating commonly exclude salt and animal products from their diets, which may predispose them to iodine deficiency even without significant weight loss. Overconsumption of dietary supplements and "natural" foods are also commonly observed among eating disorder patients. This report describes an adolescent female with disordered eating presenting with growth and pubertal delay, found to have severe iodine deficiency (urine iodine of 18 mcg/L) and abnormal thyroid function resulting from strict avoidance of salt and animal products despite adequate caloric intake...

OBJECTIVE: Current evidence from clinical studies suggests that having an active eating disorder (ED) during pregnancy is associated with unfavorable obstetric outcomes. However, the role of a lifetime diagnosis of ED is not fully understood. Variations in findings suggest a need for additional studies of maternal ED. This study aims to identify associations between a lifetime ED and obstetric outcomes. METHOD: Data from a hospital patient register and a population-based study (The HUNT Study) were linked to the Medical Birth Registry in Norway...

OBJECTIVE: To evaluate the feasibility, acceptability, and preliminary efficacy of a couple-based intervention for binge-eating disorder (BED), called UNiting couples In the Treatment of Eating disorders-BED edition (UNITE-BED). METHOD: In an open pilot trial, 11 couples in which one or both adult partners had a diagnosis of DSM-5 threshold or sub-threshold BED participated in 22 weekly sessions of UNITE-BED. Patients also received individual treatment, outside of the context of the trial...

OBJECTIVE: Body image (BI) disturbances are one of the core symptoms of anorexia nervosa (AN). They have been shown to be associated with depression and anxiety at all treatment stages and are a reliable predictor of relapse. Considering the importance for the course of AN, direct targeting of BI disturbances is still underemphasized in the treatment of patients with AN. METHOD: In this systematic review, conducted according to the PRISMA statement, the evidence on BI directed interventions in AN is synthesized...

In the United States, the past decade has seen rapid growth in treatment centers providing specialty care to patients with eating disorders. Much of this growth has been in higher levels of care, including hospital-based and residential treatment. Despite this expansion, there remains lack of agreement regarding the most important components of care, such as staff training or specifics of treatment delivery. Additionally there is no consensus on how best to assess outcome and compare performance across programs...

OBJECTIVE: Little epidemiological evidence exists on rumination disorder behavior (RB) and pica behavior (PB). We examined prevalence of RB and PB and presence of comorbid feeding/eating disorder symptoms among school-aged children. METHOD: In elementary schools in Switzerland, 1,430 children (54.0% female) ages 7-13 completed the Eating Disorder Examination-Questionnaire for children (ChEDE-Q) and the Eating Disturbances in Youth Questionnaire (EDY-Q). RESULTS: EDY-Q behavior frequency showed 9...

According to Self-Determination Theory, when motivation to reach an objective is fully internal, it is said to be "autonomous"; when driven by external incentives, it is said to be "controlled". Previous research has indicated that autonomously motivated individuals show better response to treatments for eating disorders. OBJECTIVE: In individuals undergoing different intensities of outpatient treatment for an eating disorder, we sought to assess associations between autonomous and controlled motivations and response to treatment on the one hand, and likelihood of dropping out of treatment, on the other...

OBJECTIVE: Despite changes to the diagnostic criteria for eating disorders (EDs) in the DSM-5, the current diagnostic system for EDs has limited ability to inform treatment planning and predict outcomes. Our objective was to test the clinical utility of a novel dimensional approach to understanding the structure of ED psychopathology. METHOD: Participants (N = 243; 82.2% women) were community-recruited adults with a DSM-5 ED assessed at baseline, 6-month, and 1-year follow-up...

OBJECTIVE: The eating behavior of individuals with eating disorders has been examined in laboratory settings over the last 30 years. In this focused review, we build on prior research and highlight several feeding laboratory paradigms that have successfully demonstrated quantifiable and observable behavioral disturbances, and thereby add rigor and reproducibility to the examination of disturbances of eating behavior. This review describes the measures commonly obtained via these laboratory techniques...

OBJECTIVE: Emotional eating has been linked to ovarian hormone functioning, but no studies to-date have considered the role of brain function. This knowledge gap may stem from methodological challenges: Data are heterogeneous, violating assumptions of homogeneity made by between-subjects analyses. The primary aim of this paper is to describe an innovative within-subjects analysis that models heterogeneity and has potential for filling knowledge gaps in eating disorder research. We illustrate its utility in an application to pilot neuroimaging, hormone, and emotional eating data across the menstrual cycle...

OBJECTIVE: Individuals with eating disorders are theorized to have basic impairments in affective appraisal and social-emotional processing that contribute to pathogenesis of the disease. We aimed to determine if facial electromyography could be used to discriminate between happy and disgust emotions during simultaneous acquisition of an fMRI BOLD sequence in efforts to establish a novel tool for investigating emotion-driven hypotheses about eating pathology. In line with standards for rigor and reproducibility, we provide detailed protocols and code to support each step of this project...
