[Mortality due to causes correlatable to asbestos in a cohort of workers in railway car construction]. / La mortalità per cause correlabili all'amianto in una coorte di addetti alla costruzione di carrozze ferroviarie.

A study was made of the mortality experience of a cohort of railway carriage construction workers with the aim of detecting asbestos-induced disease. The cohort included 1534 men who were active as at 01.01.1970 and/or hired up to 30.06.89. Vital status was ascertained for 97.7% of the cohort. The mortality experience of the cohort was compared with that of the population of the Campania Region. Altogether, 194 deaths were observed (SMR: 0.88). Significant mortality deficits were associated with circulatory causes (SMR: 0.64, 58 observed), non-malignant respiratory causes (SMR: 0.59, 12 observed), and accidents (SMR: 0.39, 5 observed). A significant increase in mortality from all neoplasms was detected (SMR: 1.25, 69 observed), mainly due to an excess of lung cancer (SMR: 1.45, 28 observed), pleural cancer (SMR: 4.72, 3 observed), and peritoneal cancer (SMR: 7.47, 2 observed). The excess of mortality from respiratory neoplasms mainly affected subjects who had started employment more than 20 years previously.
