Abstract
Rationale: New Orleans residents and workers have had exposures to bioaerosols and other noxious contaminants left by the floodwaters of Hurricane Katrina. In a longitudinal study to examine associations between work in and around flood-damaged structures and the risks of respiratory illness, baseline findings are presented. Methods: Spirometry was performed on 594 participants who worked for various public and private institutions, or were private residents of the New Orleans area, with some restoring/remediating their own homes. Administered questionnaire included information on respiratory health, smoking history, and pre- and post-Katrina work and occupation. Any time since Katrina spent in demolition, trash removal, landscape restoration, sewer line repair, or mold remediation ("dirty jobs") was taken as indicating exposure to flood-related contaminants. An interview question about transient fever and cough at the end of a workday was used as an indicator of possible hypersensitivity or toxic reaction. Multiple linear regression was used to relate percent predicted (%P) FEV1, FVC and FEV1/FVC to exposure, after adjusting for smoking category. Results: 74% of study participants reported time spent in at least one of the dirty jobs. The table shows that significant differences between exposed and nonexposed subjects were observed for %P FEV1 for current smokers and for %P FEV1/FVC for ex- and never smokers. 31% of study participants reported at least one episode of transient fever/cough since Katrina, and a significantly increased risk was observed with dirty jobs (RR =1.51, p = 0.007, CI: 1.10-2.09). This association was also observed in ex- and never smokers (RR = 1.78, p = 0.003, CI: 1.19-2.67), but not in current smokers (RR = 1.07, p=.80, CI: 0.64-1.7796). No significant differences in %P FEV1, FVC and FEV1/FVC were observed between subjects with and without fever/cough. Conclusions: Baseline symptoms and lung function data may be reflecting inhalant exposures to contaminants left in the wake of flooding from Hurricane Katrina.
