目的：调查葡萄牙年轻女性社区样本中是否存在成群的暴食症症状。方法：共有 2028 名 12-23 岁女性完成了饮食失调检查问卷（EDE-Q）。对七种贪食症症状、年龄和体重指数应用了潜在类别分析。结果：所选的 4 类解决方案产生了“健康”类别，报告了最少的暴食和清除行为。 “暴食”课，类似于暴食症。 “清除”班很少有暴饮暴食，但有频繁的补偿行为。最后，在“经典神经性贪食症”课程中，95％的参与者报告了暴食事件，并且补偿行为经常得到认可。所有潜在类别的 EDE-Q 总体和子量表得分均不同。结论：在社区中，存在三种自然模式：暴食加补偿行为、仅暴食以及在没有暴食的情况下进行清除。这些结果对饮食失调疾病分类学的未来修订具有影响。 (c) 2007 年，Wiley periodicals, Inc.
Objective: To investigate whether clusters of bulimic symptoms exist in a community sample of young Portuguese women.Method: A total of 2028 females, aged 12-23 years, completed the Eating Disorder Examination Questionnaire (EDE-Q). Latent class analysis was applied to the seven bulimic symptoms, age, and body mass index.Results: The selected 4-class solution yielded a "healthy" class, reporting minimal binge eating and purging behaviors. A "binge eating" class, resembled binge eating disorder. A "purging" class had infrequent binge eating, but frequent compensatory behaviors. Finally, in a "classic bulimia nervosa" class, binge eating episodes were reported by 95% of participants, and compensatory behaviors were frequently endorsed. EDE-Q global and subscale scores differed across all latent classes.Conclusion: In the community, three natural patterns exist: binge eating plus compensatory behaviors, binge eating only, and purging in the absence of binge eating. These results have implications for future revisions of eating disorders nosology. (c) 2007 by Wiley Periodicals, Inc.
