OBJECTIVE
To compare the pathway to binge eating and clinical characteristics of binge eating disorder patients (BED) and nonpurging bulimics.
METHODS
The subjects were 45 nonpurging bulimics and 45 BED patients who consecutively sought treatment in an outpatient eating disorders unit. The subjects underwent a clinical interview and replied to the Eating Disorders Inventory and the Hopkins Symptom Checklist.
RESULTS
In most of the nonpurging bulimics (89%), binge eating is preceded by dieting and weight loss, whereas among BED patients the pathway to binge eating is more variable. Previous episodes of anorexia nervosa are significantly more frequent among nonpurging bulimics than among BED patients. The two groups did not differ in other clinical and psychological characteristics, such as psychiatric symptoms, frequency of binging, and impulsivity traits. However, on many of the variables, the BED group shows a significantly greater variance.
DISCUSSION
Unlike nonpurging bulimics, BED patients appear to form a more heterogeneous group.
目的
比较暴饮暴食症患者（BED）和非清除型贪食症患者的暴饮暴食途径及临床特征。
方法
研究对象为45名非清除型贪食症患者和45名BED患者，他们在一家门诊饮食失调科连续寻求治疗。研究对象接受了临床访谈，并回答了饮食失调量表和霍普金斯症状清单。
结果
在大多数非清除型贪食症患者（89%）中，暴饮暴食之前有节食和体重减轻的情况，而在BED患者中，暴饮暴食的途径则更为多样。非清除型贪食症患者中既往神经性厌食症发作的频率显著高于BED患者。两组在其他临床和心理特征上没有差异，如精神症状、暴饮暴食频率和冲动特质。然而，在许多变量上，BED组的方差显著更大。
讨论
与非清除型贪食症患者不同，BED患者似乎构成了一个更为异质的群体。
