Characteristics of Avoidant/Restrictive Food Intake Disorder in a Cohort of Adult Patients.
To assess and compare clinical symptoms and psychometric analysis of adult patients with avoidant/restrictive food intake disorder (ARFID) with those with anorexia nervosa (AN).



We completed a retrospective review of adult patients with a feeding and eating disorder assessed between 1990 and 2005 that qualified for a diagnosis of ARFID. Patients with ARFID were compared with those with AN, with respect to the demographics, clinical symptoms and psychometric analysis.



Using the criteria of the fifth edition of the Diagnostic and Statistical Manual, 95 (9.2%) of 1029 patients with a feeding and eating disorder met the criteria for ARFID. All patients with ARFID were women. The ARFID group had a significantly shorter duration of illness, lower rates of hospital admission history and less severe psychopathology than the AN group.



Adult patients with ARFID in this study were clinically distinct from those with AN and somewhat different from paediatric patients with ARFID in previous studies. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.
