title: Mortality among coal miners with pneumoconiosis in Poland.
abstract: A mortality cohort study was carried out on 7,065 coal miners with pneumoconiosis first diagnosed during the years of 1970-85. The cohort was selected from among subjects entered into the National Register of Occupational Diseases and followed up through to the end of 1991. The general male population of Poland was considered as a reference group. The PYRS-3 programme was used to identify, by means of standardized mortality ratios (SMRs), total and selected cause-specific mortality. An analysis revealed significantly elevated total mortality (SMR = 105; 95% confidence interval (CI): 100-110) in the whole cohort of coal miners. The risk of selected cause-specific mortality was significantly enhanced due to diseases of the respiratory system among which pneumoconiosis predominated (SMR = 383; 95% CI: 345-424). While mortality from all diseases of the circulatory system (SmR = 89; CI: 82-96), arterial hypertension (SMR = 63; 95% CI: 38-98), cerebrovascular diseases (SMR = 79; 95% CI: 62-99), atherosclerosis (SMR = 79; 95% CI: 66-93), and injury in poisoning (SMR = 50; 95% CI: 38-64) was significantly lower. The risk of death from malignant neoplasm of lung in the whole study population as well as in individual groups and categories of coal miners with pneumoconiosis, which varied in the risk of pneumoconiosis and the level of exposure to ionizing radiation, was not increased.
