Feeding and eating disorders in childhood.

Abstract: Objective: To review the literature related to the current DSM-IV-TR diagnostic criteria for feeding disorder of infancy or early childhood; pica; rumination disorder; and other childhood presentations that are characterized by avoidance of food or restricted food intake, with the purpose of informing options for DSM-V. Method: Articles were identified by computerized and manual searches and reviewed to evaluate the evidence supporting possible options for revision of criteria. Results: The study of childhood feeding and eating disturbances has been hampered by inconsistencies in classification and use of terminology. Greater clarity around subtypes of feeding and eating problems in children would benefit clinicians and patients alike. Discussion: A number of suggestions supported by existing evidence are made that provide clearer descriptions of subtypes to improve clinical utility and to promote research. © 2010 American Psychiatric Association.

Prevalence and characteristics of avoidant/restrictive food intake disorder in a cohort of young patients in day treatment for eating disorders

Abstract: Avoidant/Restrictive Food Intake Disorder (ARFID) is a “new” diagnosis in the recently published DSM-5, but there is very little literature on patients with ARFID. Our objectives were to determine the prevalence of ARFID in children and adolescents undergoing day treatment for an eating disorder, and to compare ARFID patients to other eating disorder patients in the same cohort. A retrospective chart review of 7-17 year olds admitted to a day program for younger patients with eating disorders between 2008 and 2012 was performed. Patients with ARFID were compared to those with anorexia nervosa, bulimia nervosa, and other specified feeding or eating disorder/unspecified feeding or eating disorder with respect to demographics, anthropometrics, clinical symptoms, and psychometric testing, using Chi-square, ANOVA, and post-hoc analysis. 39/173 (22.5%) patients met ARFID criteria. The ARFID group was younger than the non-ARFID group and had a greater proportion of males. Similar degrees of weight loss and malnutrition were found between groups. Patients with ARFID reported greater fears of vomiting and/or choking and food texture issues than those with other eating disorders, as well as greater dependency on nutritional supplements at intake. Children’s Eating Attitudes Test scores were lower for children with than without ARFID. A higher comorbidity of anxiety disorders, pervasive developmental disorder, and learning disorders, and a lower comorbidity of depression, were found in those with ARFID. This study demonstrates that there are significant demographic and clinical characteristics that differentiate children with ARFID from those with other eating disorders in a day treatment program, and helps substantiate the recognition of ARFID as a distinct eating disorder diagnosis in the DSM-5.

Exploring avoidant/restrictive food intake disorder in eating disordered patients: a descriptive study.

Abstract: Objective To assess and compare clinical characteristics of patients with avoidant/restrictive food intake disorder (ARFID) to those with anorexia nervosa (AN). Method A retrospective review of adolescent eating disorder (ED) patients assessed between 2000 and 2011 that qualified for a diagnosis of ARFID was completed. A matched AN sample was used to compare characteristics between groups. Results Two hundred and five patients met inclusion criteria and were reviewed in detail. Of these, 34 (5%) patients met criteria for ARFID. A matched sample of 36 patients with AN was used to draw comparisons. Patients with ARFID were younger than those with AN, more likely to present before age 12, and more likely to be male. Patients in both groups presented at low weights. Common eating-specific behaviors and symptoms in the ARFID group included food avoidance, loss of appetite, abdominal pain, and fear of vomiting. Rates of comorbid psychiatric diagnoses and medical morbidity were high in both groups. Almost 80% of AN patients and one-third of ARFID patients required hospital admission as a result of medical instability. Symptom profiles in 4/34 ARFID patients resulted in eventual reclassification to AN. Discussion This study supports the notion that a small percentage of adolescent patients presenting with restrictive eating disorders meet criteria for ARFID. Patients are younger than average, more likely to be male compared to adolescent AN samples, and have high rates of psychiatric and medical morbidity. The study also suggests that a proportion of patients evolve into AN as treatment progresses. © 2013 Wiley Periodicals, Inc. (Int J Eat Disord 2014; 47:495–499)

Burden and Health-Related Quality of Life of Eating Disorders, Including Avoidant/Restrictive Food Intake Disorder (ARFID), in the Australian Population

Abstract: Little is known about the epidemiology and health related quality of life (HRQoL) of the new DSM-5 diagnoses, Binge Eating Disorder (BED) and Avoidant/Restrictive Food Intake Disorder (ARFID) in the Australian population. We aimed to investigate the prevalance and burden of these disorders. We conducted two sequential population-based surveys including individuals aged over 15 years who were interviewed in 2014 (n = 2732) and 2015 (n =3005). Demographic information and diagnostic features of DSM-5 eating disorders were asked including the occurrence of regular (at least weekly over the past 3 months) objective binge eating with levels of distress , extreme dietary restriction/fasting for weight/shape control, purging behaviors, overvaluation of shape and/or weight, and the presence of an avoidant/restrictive food intake without overvaluation of shape and/or weight. In 2014 functional impact or role performance was measured with the ‘days out of role’ question and in 2015, Health Related Quality of Life (HRQoL) was assessed with the Short Form −12 item questionnaire (SF-12v1). The 2014 and 2015 3-month prevalence of eating disorders were: anorexia nervosa-broad 0.4% (95% CI 0.2–0.7) and 0.5% (0.3–0.9); bulimia nervosa 1.1% (0.7–1.5) and 1.2% (0.9–1.7); ARFID 0.3% (0.1–0.5) and 0.3% (0.2–0.6). The 2015 3-month prevalence rates were: BED-broad 1.5% (1.1–2.0); Other Specified Feeding or Eating Disorder (OSFED) 3.2 (2.6–3.9); and Unspecified Feeding or Eating Disorder (UFED) 10.4% (0.9–11.5). Most people with OSFED had atypical anorexia nervosa and majority with UFED were characterised by having recurrent binge eating without marked distress. Eating disorders were represented throughout sociodemographic groups and those with bulimia nervosa and BED-broad had mean weight (BMI, kg/m2) in the obese range. Mental HRQoL was poor in all eating disorder groups but particularly poor for those with BED-broad and ARFID. Individuals with bulimia nervosa, BED-broad and OSFED-Purging Disorder also had poor physical HRQoL. ARFID and bulimia nervosa groups had lower role performance than those without an eating disorder. Whilst full spectrum eating disorders, including ARFID, were less common than OSFED or UFED, they were associated with poor mental HRQoL and significant functional impairment. The present study supports the movement of eating disorders in to broader socio demographic groups including men, socio-economic disadvantaged groups and those with obesity.
