The empirical structure of eating disorder (ED) pathology has often been studied in female, clinical samples, leaving questions about the structure of ED pathology in males and nonclinical samples.
A latent class analysis was performed on data combined from two different studies (N = 1,751) using the behavioral items in the Eating Disorder Examination Questionnaire (EDE-Q; binge eating, self-induced vomiting, laxative use, and excessive exercise), with the addition of an item representing restraint. Validation analyses examined weight, shape, and eating concern among the classes.
Three similar classes emerged for both the men and women's models: very low ED behaviors, binge eating, and high ED behaviors.
These results suggest that binge eating occurs within the context of lower symptom and higher symptom presentations, and that the empirical structure of ED symptoms does not differ in men and women in the nonclinical population. Further research is needed to clarify whether ED phenotypes differ in men and women.
饮食失调（ED）病理学的实证结构通常在女性临床样本中进行研究，这使得男性和非临床样本中 ED 病理学的结构问题仍未得到解答。
使用饮食失调检查问卷（EDE-Q）中的行为项目（暴食、自我诱导呕吐、泻药使用和过度运动），结合来自两项不同研究的数据（N=1751），对数据进行潜在类别分析，其中还增加了一个表示节制的项目。验证分析检查了各分类中的体重、体型和饮食关注。
男性和女性模型都出现了三个相似的类别：极低 ED 行为、暴食和高 ED 行为。
这些结果表明，暴食行为发生在低症状和高症状表现的背景下，非临床人群中男性和女性的 ED 症状实证结构没有差异。需要进一步的研究来澄清 ED 表型在男性和女性中是否存在差异。
