Pulmonary function testing is widely accepted as an integral part of medical surveillance of occupational lung diseases. There are several cross-sectional studies evaluating lung function among asbestos-exposed workers, but only few longitudinal surveys have been performed. ⋯ The results of this follow-up study showed that smoking and previous asbestos exposure were associated with a mild, but statistically significant, loss of lung function. Radiological findings of pleural plaques were not related to deterioration of lung function over the follow-up period.
