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. |
