背景：许多危险因素与神经性厌食症的发展有关。关于它们的相对贡献知之甚少，在大多数情况下也不清楚它们是否是神经性厌食症的特异性或所有进食障碍或一般精神障碍的风险因素。我们采用病例对照设计，将67名有神经性厌食症病史的女性受试者与204名健康对照受试者、102名其他精神疾病受试者进行比较，和102名神经性贪食症患者。广泛的危险因素进行了评估interview.Results：神经性厌食症的受试者和健康对照组不同，他们暴露于大多数假定的危险因素。一旦考虑到其他类别的风险因素的影响，没有更多的暴露于增加节食可能性的因素。病前完美主义和消极的自我评价尤其普遍，比一般精神病对照组更摩罗。父母的肥胖和初潮早期，连同父母的精神疾病，区分与神经性贪食症从那些与anorexia nervosa.Conclusions：神经性厌食症和神经性贪食症，其中一些是共享与其他精神疾病的危险因素似乎有很大的范围。与神经性厌食症相比，增加节食可能性的因素似乎对神经性贪食症的风险因素有更重要的影响。完美主义和消极的自我评价似乎是两种饮食失调症特别常见和特征的前因。
Background: Many risk factors have been implicated in the development of anorexia nervosa. Little is known about their relative contributions, nor in most cases is it clear whether they are specific to anorexia nervosa or risk factors for all eating disorders or for psychiatric disorder in general.Methods: We used a case-control design involving the comparison of 67 female subjects with a history of anorexia nervosa ni th 204 healthy control subjects, 102 subjects with other psychiatric disorders, and 102 subjects with bulimia nervosa. A broad range of risk factors was assessed by interview.Results: The subjects with anorexia nervosa and the healthy controls differed in their exposure to most of the putative risk factors. There was no greater exposure to factors that increased the likelihood of dieting, once the influence of other classes of risk factors had been taken into account. Premorbid perfectionism and negative self-evaluation were especially common and moro so than among the general psychiatric controls. Parental obesity and an early menarche, together with parental psychiatric disorder, distinguished those with bulimia nervosa from those with anorexia nervosa.Conclusions: There appears to be a broad range of risk factors for anorexia nervosa and bulimia nervosa, some of which are shared with other psychiatric disorders. Factors that increase the likelihood of dieting seem to have more important influence as risk factors for bulimia nervosa than anorexia nervosa. Perfectionism and negative self-evaluation appear to be particularly common and characteristic antecedents of both eating disorders.
