Rescue workers (policemen, firefighters, emergency medical staff, etc.) experience intense stress due to rescuing and helping victims of accidents, terrorist attacks, violent crimes, and natural disasters. Overexposure and ineffective coping with such stressful events may lead to developing Post-Traumatic Stress Disorder (PTSD). Meta-regression procedures were applied to examine moderators such as the sample sex composition, age, working experience, occupation, country, or type of PTSD evaluation. The 9.8% PTSD prevalence found here was virtually the same compared with earlier findings from 10 years ago. There was a large heterogeneity, however, associated with geographical location and the instrument used to evaluate PTSD. The main findings revealed that rescue workers are a high-risk group with increased levels of Post-traumatic Stress Disorder (PTSD). Moreover, PTSD prevalence could depend on a great extent on geographical and cultural factors, and on the type of PTSD evaluation.

救援人员仍然面临危险吗？全球创伤后应激障碍患病率和危险因素的荟萃回归分析

救援人员（警察、消防员、紧急医疗人员等）因救援和帮助事故、恐怖袭击、暴力犯罪和自然灾害的受害者而承受着巨大的压力。过度暴露和无效应对此类压力事件可能会导致创伤后应激障碍（PTSD）。应用元回归程序来检查调节因素，例如样本性别构成、年龄、工作经验、职业、国家或 PTSD 评估类型。这里发现的 9.8% PTSD 患病率与 10 年前的早期调查结果几乎相同。然而，与地理位置和用于评估 PTSD 的工具相关，存在很大的异质性。主要调查结果显示，救援人员是创伤后应激障碍（PTSD）水平较高的高危群体。此外，PTSD 患病率在很大程度上取决于地理和文化因素以及 PTSD 评估的类型。
