To examine prevalence and clinical correlates of eating disorder not otherwise specified (EDNOS) in the US population.
Two cross-sectional surveys of adults and adolescents used the WHO CIDI to assess DSM-IV criteria for anorexia nervosa (AN), bulimia nervosa (BN), and EDNOS.
Lifetime prevalence of EDNOS was 4.78% in adolescents and 4.64% in adults. The majority of adolescents and adults with an eating disorder presented with EDNOS. Three-quarters of participants with EDNOS met criteria for comorbid disorders, while one-quarter endorsed suicidality. Severity correlates were equally prevalent in EDNOS and AN, whereas comparisons between EDNOS and BN varied by specific correlate and sample. Adolescents with subthreshold AN (SAN) endorsed more anxiety than AN (p < .05), and adolescents and adults with SAN endorsed more suicidal plans than AN (p's < .05).
Findings increase our understanding of the clinical relevance of EDNOS. Eating disorder diagnostic nomenclature requires modification to capture the full spectrum. © 2012 by Wiley Periodicals, Inc. Int J Eat Disord 2012.
在美国人群中调查未特定的饮食障碍(EDNOS)的流行率和临床相关性。
两项横断面调查分别针对成年人和青少年,使用世界卫生组织的 CIDI 评估 DSM-IV 对神经性厌食症(AN)、神经性贪食症(BN)和 EDNOS 的标准。
青少年的终生 EDNOS 患病率为 4.78%,成年人的患病率为 4.64%。大多数患有饮食障碍的青少年和成年人表现为 EDNOS。四分之三的 EDNOS 患者符合合并症标准,而四分之一的患者有自杀倾向。严重程度相关性在 EDNOS 和 AN 中同样普遍,而 EDNOS 和 BN 之间的比较因具体相关性和样本而异。亚临床 AN(SAN)的青少年比 AN 有更多的焦虑(p<.05),SAN 的青少年和成年人比 AN 有更多的自杀计划(p's<.05)。
研究结果增加了我们对 EDNOS 临床相关性的理解。饮食障碍的诊断命名需要修改以捕捉全部范围。©2012 年 Wiley 期刊公司。国际饮食失调杂志 2012 年。
