[Cause-specific mortality of asbestos-cement workers compensated for asbestosis in the city of Bari].

The cause-specific mortality of 233 asbestos cement workers employed by the Fibronit company in Bari and compensated for asbestosis was investigated. Cohort members were enrolled on 31.12.1979 and followed through 30.4.1997; follow-up was completed for 98.3% of study subjects, and causes of death were ascertained for 96.6% of deceased subjects. Observed mortality was contrasted to that expected according to cause-sex-age- and calendar time-specific rates of the population resident in the Apulia Region. All causes observed mortality exceeded expected value (SMR: 117, 87 observed), due to a significant' increase in pneumoconiosis (SMR: 11238, 14 observed) and malignant neoplasms (SMR: 163, 38 observed)). A significant decrease of circulatory diseases was found (SMR: 64, 18 observed). Among cancer deaths, the following sites showed a significant excess: lung (SMR: 206, 17 observed), pleura (SMR: 2551, 4 observed), mediastinum (SMR: 2367, 2 observed) and peritoneum (SMR: 2877, 2 observed). The excess mortality due to asbestosis, respiratory cancer and peritoned neoplasms can be causally attributed to occupational asbestos exposure.
