ABSTRACT

Posttraumatic stress disorder (PTSD) is common among individuals with eating disorders (ED) including anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED). Comorbidity prevalence estimates for these disorders vary widely from 1% to 57%. The present study aimed to quantitatively synthesize all known prevalence rates to assess the comorbidity of PTSD and ED. Summons and Google Scholar were utilized to find peer-reviewed publications, resulting in 29 relevant articles consisting of 33 samples. Findings revealed that the pooled prevalence of PTSD in ED samples was 24.59% when weighted by study quality and 18.35% when weighted by study sample size. Among samples of individuals with PTSD diagnoses, the prevalence of ED was 20.05% when weighted by quality and 0.39% when weighted by sample size. Pooled prevalence findings within an ED population and within a PTSD population when weighted by study quality were: 17.52%, 10.83% for AN; 20.73%, 11.73% for BN; and 21.54%, 3.24% for BED, respectively. Findings suggest meaningful implications for clinicians treating individuals with PTSD and/or ED. It is recommended that clinicians become more aware of the co-occurrence of ED-PTSD and integrate this information in clinical practice when working with individuals affected by either disorder.

摘要

创伤后应激障碍 (PTSD) 在患有进食障碍 (ED) 的个体中很常见，包括神经性厌食症 (AN)、神经性贪食症 (BN) 和暴食症 (BED)。这些疾病的合并症患病率估计在 1% 到 57% 之间变化很大。本研究旨在定量综合所有已知的患病率，以评估 PTSD 和 ED 的合并症。Summons 和 Google Scholar 被用来查找同行评议的出版物，产生了 29 篇相关文章，包括 33 个样本。研究结果显示，ED 样本中 PTSD 的综合患病率在按研究质量加权时为 24.59%，在按研究样本量加权时为 18.35%。在诊断为 PTSD 的个体样本中，ED 的患病率按质量加权时为 20.05%，按样本量加权时为 0.39%。按研究质量加权时，ED 人群和 PTSD 人群中的汇总患病率结果为：17.52%，AN 为 10.83%；20.73%，国阵 11.73%；BED 分别为 21.54%、3.24%。研究结果表明，对于临床医生治疗患有 PTSD 和/或 ED 的个体具有重要意义。建议临床医生在与受这两种疾病影响的个体一起工作时，更加意识到 ED-PTSD 的共同发生，并将这些信息整合到临床实践中。
