Eating disorders (ED) are associated with a higher prevalence of post-traumatic stress disorder (PTSD). However, the impact they may have on the clinical features and severity of the ED remains unknown. In this study, we assessed the prevalence and the impact of PTSD in a disordered eating population sample.
We recruited patients with eating disorders during a period of 6 months, in 2014. The patients underwent a semistructured diagnostic interview by trained psychiatrists. The severity of eating behaviours and PTSD was assessed using the Eating Disorder Inventory 2 and the Impact of Event Scale - Revised.
One hundred and thirty patients (57 patients with anorexia nervosa, 26 with bulimia nervosa, 18 with eating disorder not otherwise specified and 29 with binge eating disorder) were included. Our analyses revealed a PTSD rate of 33.9% in patients with ED. No difference was observed between the ED subtypes. Severity of ED was significantly higher among patients suffering from PTSD. Specific clinical characteristics of the ED-PTSD association have been found. Analyses revealed a significantly higher level of insecurity, interpersonal distrust, impulsivity and a decrease of interoceptive awareness.
The frequency and negative impact of PTSD on ED reinforce the need for a systematic clinical evaluation and the implementation of specific care.
饮食失调（ED）与创伤后应激障碍（PTSD）的较高患病率相关。然而，它们对饮食失调的临床特征和严重程度可能产生的影响仍不清楚。在本研究中，我们评估了PTSD在饮食失调人群样本中的患病率及其影响。
2014年，我们在6个月的时间里招募了饮食失调患者。患者接受了由训练有素的精神科医生进行的半结构化诊断访谈。使用饮食失调量表2和事件影响量表修订版评估饮食行为和PTSD的严重程度。
纳入了130名患者（57名神经性厌食症患者、26名神经性贪食症患者、18名未另行指定的饮食失调患者和29名暴饮暴食症患者）。我们的分析显示，饮食失调患者中PTSD的发生率为33.9%。在饮食失调亚型之间未观察到差异。患有PTSD的患者中饮食失调的严重程度明显更高。已发现饮食失调与PTSD关联的特定临床特征。分析显示，不安全感、人际不信任、冲动性水平显著更高，且内感受性意识下降。
PTSD对饮食失调的频率和负面影响强化了进行系统临床评估和实施特定护理的必要性。
