Objective To investigate the cause of death of the silicotic patients of fluorite mine.
Methods A death data of silicotic patients of fluorite mine from 1963 to 2000 was analysed.
Results In the past 37 years, the accumulative total of silicotic patients were 828, and 421 died.The mortality was 50.85%.The average dead age was 54.60 years.It increased gradually with the time (F=210.21, P < 0.001).The average dead age of the tuberculosis(TB)was less than the other disease(t=5.08, P < 0.001).According to the proportional mortality rate, the main reasons causing people death were TB, silicosis and malignancy.The dead proportion of TB decreased gradually with the time.And the trend increased in the silicosis and malignancy.The death of lung cancer had a rising trend after 1990s.
Conclusion To enhance continuously and consolidate the prevention and treatment of TB and to protect the lung function were very important.The three-early prevention of the malignancy, especially the lung cancer, should be taken seriously.
