Objective This study investigates eating pathology in transgender and gender non‐conforming (TGNC) youth compared to a community‐based sample and individuals with eating disorders (EDs). Method Participants (ages 13–21 years) included TGNC youth from a paediatric gender clinic ( N = 97), a demographically matched community‐based sample of cisgende...

Objective Recovery from an eating disorder (ED) may be defined differently by different stakeholders. We set out to understand the definition of ED recovery from the perspective of patients, their parents, and clinicians. Method We recruited patients with EDs (n = 24, ages 12–23 years) representing different diagnoses (anorexia nervosa n = 17, bul...

Objective Improved treatment outcome in family‐based treatment (FBT) for anorexia nervosa (AN) is predicted by weight gain occurring early in the course of treatment (i.e., about 4 lbs by week 4). Although prior work suggests that early weight gain in higher levels of care (e.g., partial hospitalization programs [PHP]) predicts weight restoration a...

Avoidant/restrictive food intake disorder (ARFID) was introduced in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. Three different subtypes of ARFID are described: individuals who seem disinterested in eating, those who avoid certain foods because of a sensitivity to specific characteristics of the food, and those who...

Purpose Data from low-weight patients with restrictive eating disorders (EDs) treated in outpatient adolescent medicine-based ED treatment programs were analyzed to determine whether there was an association between hospitalization and gain to at least 90% median body mass index (mBMI) at 1-year follow-up. Methods Data were retrospectively collect...

Purpose of review: Avoidant/restrictive food intake disorder (ARFID) is a new eating disorder diagnosis in the 5th edition of the diagnostic and statistical manual (DSM-5), published in 2013. The purpose of this review is to describe the creation of ARFID as a diagnostic category, and to explain the DSM-5 diagnostic criteria; to demonstrate what i...

Purpose: Previous research has indicated that patients with anorexia nervosa (AN) or atypical AN with premorbid history of overweight/obesity have greater weight loss and longer illness duration than patients with no such history. However, little is known about the association of premorbid overweight/obesity and receiving inpatient medical care du...

Purpose: The National Eating Disorders Quality Improvement Collaborative evaluated data of patients with restrictive eating disorders to analyze demographics of diagnostic categories and predictors of weight restoration at 1 year. Methods: Fourteen Adolescent Medicine eating disorder programs participated in a retrospective review of 700 adolesc...

Purpose To evaluate the DSM-5 diagnosis of Avoidant/Restrictive Food Intake Disorder (ARFID) in children and adolescents with poor eating not associated with body image concerns. Methods A retrospective case-control study of 8–18-year-olds, using a diagnostic algorithm, compared all cases with ARFID presenting to seven adolescent-medicine eating d...

Purpose: To determine the distribution of eating disorders (ED) in children and adolescents comparing the fourth edition of the Diagnostic and Statistical Manual (DSM) to the proposed fifth edition DSM criteria. Methods: A total of 215 consecutive patients (15.4 ± 3.3 years) presenting for initial ED evaluation to adolescent medicine physicians...

Psychopharmacologic medications are often prescribed to patients with restrictive eating disorders (EDs), and little is known about the frequency of use in adolescents. We examined the use of psychopharmacologic medications in adolescents referred for treatment of restrictive ED, potential factors associated with their use, and reported psychiatric...

This quality improvement project collected and analyzed short-term weight gain data for patients with restrictive eating disorders (EDs) treated in outpatient adolescent medicine-based ED programs nationally. Data on presentation and treatment of low-weight ED patients aged 9-21 years presenting in 2006 were retrospectively collected from 11 indepe...

Eating disorders in children and adolescents remain a serious cause of morbidity and mortality in children, adolescents, and young adults. The working knowledge of pathophysiology, recognition, and management of eating disorders continues to evolve as research in this field continues. This article builds on previous background and position papers o...

A national survey of institutional review boards (IRBs) was conducted to determine: (1) the current practices of IRBs concerning consent for adolescent minors; and (2) the existence of support for changes in the federal regulations for research on adolescents. Six hundred surveys were mailed in two waves to all IRB chairs in the United States, with...
