Abstract

PURPOSE:

To investigate whether New York State employees who responded to the World Trade Center disaster were more likely to report asthma or lower respiratory symptoms (LRS; cough, wheeze, chest tightness, shortness of breath) than non-exposed employees, 2 years post-September 11.

METHODS:

Participants (578 exposed, 702 non-exposed) completed mailed questionnaires in 2003. A unique exposure assessment method was used; exposure scores were divided at the mean (at/below, above). Poisson regression was used.

RESULTS:

Exposure was associated with LRS, but not asthma. Participants with exposure scores at/below the mean had a twofold increased risk of most LRS. Those with scores above the mean had a three to fourfold increased risk. For scores above the mean, the magnitude of effect was consistently higher for smoke exposure.

CONCLUSIONS:

Moderately exposed responders may experience health impacts from exposures in later stages of a disaster. Exposure to smoke may have had a greater lower respiratory impact than resuspended dust.
