We used a purpose-designed questionnaire to survey the prevalence of binge-eating and bulimia in a sample of 1063 Dublin third-level students aged 17-25 yr. There were 361 males and 701 females. The questionnaire was based on DSM-III, and included a written definition of a binge and cross-check questions. Although 17.7% of males and 37% of females claimed to have had an eating binge, cross-check items reduced this to 1.1% of males and 10.8% of females who met the DSM-III definition. No male and only 7.7% of females also met the behavioural criteria under item B of DSM-III, and only 5% of females reported dysphoric mood. Excluding those experiencing fewer than one episode per week gave a prevalence of 2.8% in females and 0% on males. Previously-reported prevalences using questionnaire may be inflated due to poor respondent understanding of the psychiatric terms being used.
我们使用了一份专门设计的问卷，对1063名年龄在17至25岁的都柏林高等院校学生样本中的暴饮暴食和神经性贪食症患病率进行了调查。其中有361名男性和701名女性。该问卷基于《精神疾病诊断与统计手册》第三版（DSM-III），包括暴饮暴食的书面定义及交叉核对问题。尽管17.7%的男性和37%的女性称有过饮食暴饮暴食行为，但经过交叉核对项目后，符合DSM-III定义的男性降至1.1%，女性降至10.8%。没有男性符合DSM-III中B项的行为标准，只有7.7%的女性符合，且只有5%的女性报告有烦躁情绪。排除每周发作少于一次的情况后，女性患病率为2.8%，男性为0%。之前使用问卷报告的患病率可能因受访者对所使用的精神科术语理解不佳而被高估。
