Diagnostic Criteria for Anorexia Nervosa (DSM IV, 2000)
A.
Refusal
to maintain body weight at or above a minimally normal weight for age and
height (e.g., weight loss leading to maintenance of body weight less than 85%
of that expected; or failure to make expected weight gain during period of
growth, leading to body weight less than 85% of that expected).
B.
Intense fear of gaining weight or becoming fat, even though underweight.
C.
Disturbance in the way in which one's body weight or shape is experienced,
undue influence of body weight or shape on self-evaluation, or denial of the
seriousness of the current low body weight.
D.
In postmenarcheal females, amenorrhea, i.e., the absence of at least three
consecutive menstrual cycles. (A woman is considered to have amenorrhea if her
periods occur only following hormone, e.g., estrogen, administration)
Diagnostic Criteria for Bulimia Nervosa (DSM IV, 2000)
A.
Recurrent
episodes of binge eating. An episode of binge eating is characterized by both
of the following:
-
eating, in a discrete period of time (e.g., within any 2-hour period), an
amount of food that is
definitely larger than most people would eat during a similar period of time and under similar
circumstances
-
a sense of lack of control over eating during the episode (e.g., a feeling
that one cannot stop eating
or control what or how much one is
eating)
B.
Recurrent inappropriate compensatory behavior in order to prevent weight gain,
such as self-induced vomiting; misuse of laxatives, diuretics, enemas, or
other medications; fasting; or excessive exercise.
C.
The binge eating and inappropriate compensatory behaviors both occur, on
average, at least twice a week for 3 months.
D.
Self-evaluation is unduly influenced by body shape and weight.
E.
The disturbance does not occur exclusively during episodes of Anorexia
Nervosa.

The
Eating Disorder Not Otherwise Specified ED-NOS
category is for
disorders of eating that do not meet the criteria for any specific Eating
Disorder.
i.e.:
For
females, all of the criteria for AN are met except that the individual has
regular menses.
All
of the criteria for Anorexia Nervosa are met except that, despite significant
weight loss, the individual's current weight is in the normal range.
All
of the criteria for BN are met except that the binge Eating and inappropriate
compensatory mechanisms occur at a frequency of less than twice a week or for a
duration of less than 3 months.
The
regular use of inappropriate compensatory behavior by an individual normal body
weight after eating small amounts of food (e.g. self-induced vomiting after the
consumption of two cookies).
Repeatedly
chewing and spitting out, but not swallowing, large amounts of food.
Binge-eating
disorder: recurrent episodes of binge eating in the absence of the regular use
of inappropriate compensatory behaviors characteristic of BN.
