TABLE 1

Key Features of DSM-5 Diagnostic Criteria for Feeding Disorders and EDs

AN
 • Restriction of food eaten leading to lower than expected body weight
 • Intense fear of weight gain or being fat
 • Body image distortion
 Types: restricting or binge eating/purging
BN
 • Binge eating in which
  o a larger amount of food is eaten within a 2-hour period compared with peers; and
  o there is a perceived lack of control during the time of the binge
 • Repeated use of unhealthy behaviors after a binge to prevent weight gain: (vomiting; abuse of laxatives, diuretics, or other medications; food restriction; or excessive exercise)
 • Behaviors occur at least once a week for 3 months
 • Self-worth is overly based on body shape and weight
 • Behaviors occur distinctly apart from AN
Binge-eating disorder
 • Recurrent episodes of binge eating in which
  o a larger amount of food is eaten within a 2-hour period compared with peers; and
  o there is a perceived lack of control during the time of the binge
 Bingeing episodes are associated with at least 3 of the following:
  o eating faster than normal;
  o eating until overly full;
  o eating large quantities of food when not hungry;
  o eating alone because of embarrassment about the quantity of food eaten; and
  o feeling badly emotionally after eating
 • Upset about bingeing
 • Bingeing behavior occurs at least once a week for 3 months
 • Bingeing is not followed by the use of unhealthy behaviors to purge and does not occur during AN or BN
Avoidant/restrictive food intake disorder
 • A feeding problem that results in at least one of the following:
  o significant weight loss or failure to meet the expected weight or height gain in children;
  o significant nutritional deficiency;
  o dependence on nonfood nutrition, such as nasogastric feedings or oral nutritional supplements; or
  o marked interference with psychosocial functioning
 • The problem is not attributable to food availability or cultural ideas
 • The problem is
  o not attributable to AN, and there is no distortion in body image; and
  o not attributable to another condition, medical or mental
Other specified feeding disorder or ED
 Atypical AN: all criteria for anorexia, but weight is normal
 BN (of low frequency and/or limited duration): all criteria except for frequency
 Binge-eating disorder (of low frequency and/or limited duration): all criteria except for frequency
 Purging disorder: recurrent purging in an effort to lose weight without bingeing
