ABSTRACT
OBJECTIVE:
The aim of this study was to determine the relationship between deployment length and indices of airflow obstruction in Iraq and Afghanistan veterans with airborne hazards exposure.METHODS:
One hundred twenty-four post-9/11 veterans completed pulmonary function testing and questionnaires. We examined the association of airflow limitation [forced expiratory volume in 1âsecond (FEV1)/forced vital capacity (FVC)] and bronchodilator responsiveness (ΔFEV1 and ΔFVC) with deployment length, adjusting for smoking.RESULTS:
Longer deployment length was associated with lower FEV1/FVC [ßâ=â-0.19; 95% confidence interval (95% CI), -0.39 to 0.01], greater ΔFEV1 (ßâ=â0.27; 95% CI, 0.09 to 0.45) and ΔFVC (ßâ=â0.19; 95% CI, 0.05 to 0.33). In our model adjusted for smoking history, longer deployment length remained associated with greater ΔFEV1 and ΔFVC (Pâ<â0.01), but not with FEV1/FVC (Pâ=â0.059).CONCLUSION:
In our sample of post-9/11 veterans, longer deployment lengths were associated with significant bronchodilator responsiveness and a trend toward airflow limitation independent of tobacco use.
