世界贸易中心消防员咳嗽综合征和可能的PTSD共患病趋势
2011/07/06
摘要
背景:我们描述9/11后第1年(基线)和3~4年(随访)后,世贸中心(WTC)暴露的消防员的咳嗽综合征、肺功能与可能存在的创伤后应激障碍(PTSD)症状之间的关系。
方法:5363名消防员在两个时间点完成了肺功能检测(PFTs)和问卷调查。采用简单和多变量模型,分析咳嗽综合症与可能的PTSD和PFTs之间的关系。此外,我们同时研究了包括WTC暴露在内的影响因子。
结果:基线状态下,有1561名消防员(29.1%)出现咳嗽综合征,随访期有1186名(22.1%)出现咳嗽综合征,包括559名迟发型咳嗽综合征消防员(仅在随访期出现)。基线状态有458名(8.5%)消防员可能存在PTSD,而在随访期为548名消防员,包括343名迟发型PTSD。基线状态的PTSD症状数和可能的PTSD与基线状态和随访期内的WTC咳嗽综合征相关,那些迟发型咳嗽综合征患者也存在该相关性。与此类似,基线状态下WTC咳嗽综合征症状数和WTC咳嗽综合征与基线状态和随访期的可能PTSD相关,迟发型PTSD患者也存在该相关性。WTC到达时间和工作时间是两者转归的影响因子。肺功能和WTC咳嗽综合征间存在较弱但持续的相关性,但未在PTSD中观察到。
结论:WTC咳嗽综合征和可能的PTSD存在着中度相关性。其中一个因素的出现,可增加另一因素的发生,即使是在影响因素(如WTC暴露)校正后也如此。

Abstract
BACKGROUND:
We describe the relationship between World Trade Center (WTC) Cough Syndrome symptoms, pulmonary function, and symptoms consistent with probable Post-Traumatic Stress Disorder (PTSD) in WTC-exposed firefighters in the first year post-9/11 (baseline) and 3-4 years later (follow-up).
METHODS:
5,363 firefighters completed pulmonary function tests (PFTs) and questionnaires at both times. Relationships between WTC Cough Syndrome, probable PTSD and PFTs were analyzed using simple and multivariable models. We also examined the effects of cofactors including WTC exposure.
RESULTS:
WTC Cough Syndrome was found in 1,561 (29.1%) firefighters at baseline and 1,186 (22.1%) at follow-up, including 559 with delayed onset (present only at follow-up). Probable PTSD was found in 458 (8.5%) firefighters at baseline and 548 (10.2%) at follow-up, including 343 with delayed onset. Baseline PTSD symptoms counts and probable PTSD were associated with WTC Cough Syndrome at baseline, at follow-up and in those with delayed onset WTC Cough Syndrome. Similarly, WTC Cough Syndrome symptom counts and WTC Cough Syndrome at baseline were associated with probable PTSD at baseline, at follow-up, and in those with delayed onset probable PTSD. WTC arrival time and work duration were cofactors of both outcomes. There was a small but consistent association between pulmonary function and WTC Cough Syndrome, but none with PTSD.
CONCLUSIONS:
There was a moderate association between WTC Cough Syndrome and probable PTSD. The presence of one contributed to the likelihood of the other, even after adjustment for shared cofactors like WTC exposure
