Eating Disorders飲食障礙

Anorexia Nervosa 神經性厭食症

1. 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).

拒絕維持與身高年齡相應的基本體重（比如：體重的丟失導致體重少於應有體重的85％；或者達不到相應階段應該增長的85％）。

2. Intense fear of gaining weight or becoming fat, even though underweight.

盡管體重低於正常，仍然非常害怕體重增加或變胖。

3. 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.

對體重或體形的關注已經造成痛苦，過分影響到對自我的評價，或者不麵對自己現在體重過輕的嚴峻事實。

4. 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.)

在育齡女性，出現不正常停經（比如；女性隻能在外用激素的情況下出現月經）

Bulimia Nervosa神經性暴食症

A. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:

反複地快速過度進食。快速過度進食有以下兩種表現：

1. 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

在一定的時間裏大量進食，所吃食物大於同樣情況下大多數人所進食的量。

2. 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)進食後又感到失去控製的自責（比如：感到自己不能停止進食，或不能控製進食的量）
   
   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.反複使用不恰當的補償手段以防止體重因暴食增加，引吐，泄藥，灌腸，禁食，過度運動。

C. The binge eating and inappropriate compensatory behaviors both occur, on average, at least twice a week for 3 months.過度暴食行為和不健康的補償手段行為平均起來，至少每周發生兩次，至少發生三個月。

D. Self-evaluation is unduly influenced by body shape and weight.自我的價值過分地被體重和體形影響。

E. The disturbance does not occur exclusively during episodes of Anorexia Nervosa暴食和補償行為不僅僅發生在神經性厭食症發作時期。
