The present study aims to evaluate the occurrence of life events preceding the onset of eating problems in bulimia nervosa patients. A case-control design was used involving the comparison of 60 female subjects who meet DSM-IV criteria for bulimia nervosa with 60 healthy control subjects and 60 subjects with other psychiatric disorders. The RFI (Fairburn et al., 1998) subset of factors that represent exposure to life events in the 12 months immediately before the development of eating problems was used. Women with bulimia nervosa reported higher rates of major stress, criticism about eating, weight and shape and also a great number of antecedent life events during the year preceding the development of eating problems than the healthy control group. However, when compared with the general psychiatric control group only the exposure to critical comments about weight, shape, or eating emerged as a specific trigger for bulimia nervosa. Our findings support the fact that eating and shape/weight criticism in the year preceding the development of eating disturbance seems to be specifically related to bulimia nervosa.
本研究旨在评估神经性贪食症患者在发病前经历的生活事件。采用病例对照设计，比较了符合 DSM-IV 标准的 60 名女性神经性贪食症患者与 60 名健康对照组和 60 名其他精神障碍组患者。使用 RFI（Fairburn 等人，1998 年）亚组因素来代表在发生饮食问题前的 12 个月内接触生活事件的情况。患有神经性贪食症的女性报告在发生饮食问题前的一年中经历了更高水平的重大压力、对饮食、体重和体型的批评，以及大量的前期生活事件，而健康对照组则没有。然而，与一般精神科对照组相比，只有体重、体型或饮食方面的批评性言论的暴露被认为是神经性贪食症的特定诱因。我们的研究结果支持这样一种观点，即在出现饮食紊乱前一年中，关于饮食和体型/体重的批评似乎与神经性贪食症有特定的关系。
