Feeling and body investigators (FBI): ARFID division-An acceptance-based interoceptive exposure treatment for children with ARFID.

Objective: Individuals with Avoidant Restrictive Food Intake Disorder (ARFID) experience impairing health consequences from insufficient nutritional variety and/or quantity. Early medical conditions and/or somatic symptoms such as abdominal pain may lead some with ARFID to experience somatic sensations as aversive. As such, food avoidance may be part of a broader behavioral repertoire aimed at suppressing bodily sensations.

The significance of repetitive hair-pulling behaviors in eating disorders.

We studied the relation between intrusive and repetitive hair pulling, the defining feature of trichotillomania, and compulsive and impulsive features in 1,453 individuals with anorexia nervosa and bulimia nervosa. We conducted a series of regression models examining the relative influence of compulsive features associated with obsessive-compulsive disorder, compulsive features associated with eating disorders, trait features related to harm avoidance, perfectionism, and novelty seeking, and self harm. A final model with a reduced sample (n = 928) examined the additional contribution of impulsive attributes.

Life beyond the eating disorder: education, relationships, and reproduction.

Objective: We investigated the sociodemographic characteristics in women with and without lifetime eating disorders.

Method: Participants were from a multisite international study of eating disorders (N = 2,096). Education level, relationship status, and reproductive status were examined across eating disorder subtypes and compared with a healthy control group.

Childhood anxiety associated with low BMI in women with anorexia nervosa.

Objective: Extremely low body mass index (BMI) values are associated with increased risk for death and poor long-term prognosis in individuals with anorexia nervosa (AN). The present study explores childhood personality characteristics that could be associated with the ability to attain an extremely low BMI.

Methods: Participants were 326 women from the Genetics of Anorexia Nervosa (GAN) Study who completed the Structured Interview for Anorexia Nervosa and Bulimic Syndromes and whose mother completed the Child Behavioral Checklist and/or Revised Dimensions of Temperament Survey.

Influence of overanxious disorder of childhood on the expression of anorexia nervosa.

Objective: Childhood anxiety often precedes the onset of anorexia nervosa (AN) and may mark a liability to the emergence of an eating disorder for some women. This study investigates the prevalence of overanxious disorder (OAD) among women with AN and explores how OAD impacts AN symptoms and personality traits.

Method: Participants were 637 women with AN who completed an eating disorders history, the Structured Clinical Interview for DSM-IV Axis I Disorders, and assessments for childhood anxiety, eating disorder attitudes, and associated personality traits.

Features associated with diet pill use in individuals with eating disorders.

We investigated the relation between diet pill use and eating disorder subtype, purging and other compensatory behaviors, body mass index (BMI), tobacco and caffeine use, alcohol abuse or dependence, personality characteristics, and Axis I and Axis II disorders in 1,345 participants from the multisite Price Foundation Genetics Studies. Diet pill use was significantly less common in women with restricting type of AN than in women with other eating disorder subtypes. In addition, diet pill use was associated with the use of multiple weight control behaviors, higher BMI, higher novelty seeking, and the presence of anxiety disorders, alcohol abuse or dependence, and borderline personality disorder.

Patterns of menstrual disturbance in eating disorders.

Objective: To describe menstrual disturbance in eating disorders (ED).

Method: We describe menstrual history in 1,705 women and compare eating, weight, and psychopathological traits across menstrual groups.

Results: Menstrual dysfunction occurred across all eating disorder subtypes.

Smoking in eating disorders.

Objective: Smoking has been reported as an appetite and weight control method in eating disorders; however, few studies have explored patterns of smoking across subtypes of eating disorders. The aim of this paper was to explore the patterns and prevalence of smoking behavior in 1,524 women from two of the multisite Price Foundation Genetic studies.

Method: Smoking behavior was assessed in 306 individuals with anorexia nervosa-restricting type (RAN), 186 with anorexia nervosa-purging type (PAN), 180 with anorexia nervosa and bulimia nervosa (ANBN), 107 with anorexia nervosa-binging type (BAN), 71 individuals with purging type-bulimia nervosa (PBN), and 674 female community controls.

Features associated with excessive exercise in women with eating disorders.

Objective: Excessive exercise and motor restlessness are observed in a substantial number of patients with eating disorders. This trait has been studied extensively among animal models of activity anorexia nervosa (AN) and may hold particular interest as an endophenotype for AN. We explored features associated with excessive exercise across subtypes of eating disorders.

Relationships between features associated with vomiting in purging-type eating disorders.

Objective: Vomiting is a pernicious symptom of eating disorders. We explored the relation between the symptom of vomiting and features of eating disorder course and severity, personality traits, and Axis I and II comorbidity in individuals with purging-type eating disorders.

Method: The sample included participants from the multisite, international Price Foundation Genetic Studies, who had an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified) and had data available for the frequency of purging behaviors (n = 1,048).

Olanzapine treatment of anorexia nervosa: a retrospective study.

Background: Recent reports raise the possibility that olanzapine, which commonly causes weight gain in non-eating-disordered subjects, assisted weight gain and mood during refeeding in anorexia nervosa (AN) patients.

Methods: Eighteen AN subjects who engaged in open treatment with olanzapine were retrospectively questioned about their response.

Results: Subjects reported a significant reduction in anxiety, difficulty eating, and core eating disorder symptoms after taking olanzapine.
