Abstract

We examined the association of job title and duration of employment with the smoking-adjusted prevalences of chronic bronchitis, obstruction, restriction, and mixed pulmonary function impairment in 657 white male shipyard workers aged 20 to 60 years. Logistic regression was used to compute odds ratios (OR) and confidence intervals (CI) for risk of chronic bronchitis and pulmonary function impairment. Compared to employment for less than 20 years, employment for more than 20 years was independently associated with chronic bronchitis (OR=2.0; 95% CI: 1.2-3.5), restriction (OR=2.6; CI: 1.4-4.6), and mixed impairment (OR=2.5; 95% CI: 1.1-5.5). Compared to metalworkers, which was the lowest exposure job category, four job categories were independently associated with restriction: gas welders (OR=3.6; 95% CI: 1.5-8.9), arc welders (OR=4.1; 95% CI: 1.5-11.4), masons (OR=6.2; 95% CI: 1.0-39.0), and insulators (OR=8.0; 95% CI: 1.8-35.2). These results suggest that exposure to pulmonary toxic agents in the shipyard environment can lead to both parenchymal inflammation (restriction) and airways inflammation (obstruction).
