OBJECTIVE
To evaluate (1) the Eating Disorder Not Otherwise Specified (EDNOS) prevalence in an eating disorder inpatient unit; (2) the impact of altering the diagnostic criteria for anorexia nervosa and bulimia nervosa on the prevalence of EDNOS.
METHOD
One hundred and eighty six eating disorder patients consecutively hospitalised were included in the study. The prevalence of anorexia nervosa, bulimia nervosa and EDNOS was evaluated with the Eating Disorder Examination (EDE). The EDNOS prevalence was recalculated after the alteration of three diagnostic criteria for anorexia nervosa and one for bulimia nervosa.
RESULTS
Seventy eight patients (41.9%) met the diagnostic criteria for anorexia nervosa, 33 (17.8%) for bulimia nervosa and 75 (40.3%) for EDNOS. The alteration of the DSM-IV diagnostic criteria reduced the prevalence of EDNOS to 28 cases (15%).
CONCLUSION
EDNOS is a very frequent diagnostic category in an inpatient setting. Altering the diagnostic criteria for anorexia nervosa and bulimia nervosa reduced significantly the prevalence of EDNOS.
目的
评估（1）进食障碍住院单元中未特定指明的进食障碍（EDNOS）的患病率；（2）改变神经性厌食症和神经性贪食症的诊断标准对EDNOS患病率的影响。
方法
186名连续住院的进食障碍患者纳入本研究。采用进食障碍检查（EDE）评估神经性厌食症、神经性贪食症和EDNOS的患病率。在改变神经性厌食症的三项诊断标准和神经性贪食症的一项诊断标准后，重新计算EDNOS的患病率。
结果
78名患者（41.9%）符合神经性厌食症的诊断标准，33名（17.8%）符合神经性贪食症的诊断标准，75名（40.3%）符合EDNOS的诊断标准。DSM-IV诊断标准的改变使EDNOS的患病率降至28例（15%）。
结论
在住院环境中，EDNOS是一种非常常见的诊断类别。改变神经性厌食症和神经性贪食症的诊断标准显著降低了EDNOS的患病率。
