创伤后应激障碍(PTSD)在患有进食障碍(ED)的个人中很常见，包括神经性厌食症(AN)、神经性暴食症(BN)和暴饮暴食障碍(BED)。这些疾病的合并症患病率估计值从1%到57%差别很大。本研究旨在量化综合所有已知的患病率，以评估创伤后应激障碍和勃起功能障碍的共病。利用“传唤”和“谷歌学者”检索同行评议的出版物，得到29篇相关文章，包括33个样本。结果显示，按研究质量加权和按研究样本量加权时，ED样本中PTSD的汇集患病率分别为24.59%和18.35%。在诊断为创伤后应激障碍的样本中，按质量加权的ED患病率为20.05%，按样本量加权的ED患病率为0.39%。按研究质量加权后，ED人群和PTSD人群的合并患病率分别为：AN 17.52%，10.83%；BN 20.73%，11.73%；BED 21.54%，3.24%。研究结果对临床医生治疗创伤后应激障碍和/或勃起功能障碍有重要意义。建议临床医生更多地意识到ED-PTSD的共同存在，并在治疗任何一种疾病时将这一信息整合到临床实践中。
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.
