Table_3_Non-interpersonal traumatic events in patients with eating disorders: a systematic review.xlsx

ObjectivesThe purpose of the systematic review was to synthesize literature on eating disorders (ED) and non-interpersonal traumatic events (NTE) and consolidate the reported prevalence of NTE in patients with an ED.
MethodsThe literature search was performed in Embase, PsycInfo, and PubMed. The keywords in the search were “eating disorder,” “trauma” and “non-interpersonal,” using index-terms and free-search keywords related to NTE and ED. The PRISMA guidelines were followed. Relevant studies were screened using Rayyan.
ResultsOf the 16 studies included in the quantitative synthesis, five overall types of NTE were identified: accidents, illness, injury, natural disaster and war. Findings provided tentative evidence for illness and injury being more prevalent in patients suffering from an ED compared to controls. The remaining subtypes of NTE did not show a higher prevalence in patients with an ED when compared to controls. Findings also suggest that those with binge/purge subtype of anorexia nervosa (AN) had a higher prevalence of non-interpersonal traumatic events compared to the restrictive subtype of AN.
DiscussionThis systematic review provided a clear synthesis of previous findings related to NTE among patients with an ED. Noteworthy, is that many studies do not take into account if the trauma happened prior or after to ED onset, which may affect the association. Furthermore, the body of research on NTE in patients with ED is exceedingly limited, and more research is needed.

研究目的：本项系统综述旨在整合进食障碍（eating disorders, ED）与非人际创伤事件（non-interpersonal traumatic events, NTE）相关文献，并明确进食障碍患者中非人际创伤事件的报告患病率。
研究方法：本研究检索了Embase、PsycInfo及PubMed数据库，检索关键词涵盖“进食障碍”“创伤”与“非人际”，同时采用与NTE及ED相关的规范主题词与自由检索词。研究严格遵循PRISMA指南开展，并通过Rayyan工具筛选相关研究。
研究结果：本次定量整合共纳入16项研究，最终识别出5类非人际创伤事件：事故、疾病、受伤、自然灾害与战争。研究结果初步显示，与对照组相比，进食障碍患者中疾病与受伤类创伤的患病率更高；其余类型的非人际创伤事件在进食障碍患者与对照组间未呈现显著患病率差异。此外，研究还发现，暴食/清除型神经性厌食症（anorexia nervosa, AN）患者的非人际创伤事件患病率显著高于限制型神经性厌食症患者。
讨论：本系统综述清晰整合了进食障碍患者非人际创伤事件相关的既往研究成果。值得注意的是，多数研究未考量创伤事件发生于进食障碍起病前还是起病后，这一因素可能会影响研究的关联分析结果。此外，目前针对进食障碍患者非人际创伤事件的研究体量极为有限，仍需开展更多相关研究。
