| Abstract |
A cross-sectional study of respiratory symptoms and lung function in welders was performed at eight New Zealand welding sites. Symptoms of chronic bronchitis were more common in current welders than in non-welders. Of those workers with a cumulative exposure index to welding fume ≥10 years, 16.7% reported symptoms of chronic bronchitis compared with 4.7% of those with a cumulative exposure index <4 years. Workers with chronic bronchitis had significantly lower measures of baseline peak expiratory flow and FEV1/FVC ratio than workers without chronic bronchitis. Multivariate analysis showed that current smoking and total exposure index to welding fumes >10 years were independent risk factors for chronic bronchitis. The report of any work-related respiratory symptom was more prevalent in welders than non-welders and workers with these symptoms had significantly lower FEV1 and FVC values. Multivariate analysis identified a high proportion of time spent welding in confined spaces as the main risk factor for reporting these symptoms. |
