Objective To study the epidemiological characteristics of deaths due to pneumoconiosis and its complications in order to improve the control and prevention of pneumoconiosis.
Methods A total of 169 pneumoconiosis deaths who died during January 1st 1961 through December 31st 2008 in Putuo District of Shanghai were recorded in "pneumoconiosis report card" and "dynamic recording cards of pneumoconiosis in Shanghai". All the related information from those cards was entered in to database, and analyzed by SPSS 13.0 statistical software.
Results There was a negative correlation between the working duration of dust exposure and the length of the disease course(r=-0.146, P=.029). In the direct causes of the deaths of the victims, pneumoconiosis itself was the first cause (31.95%), and the second cause was cancer of trachea, bronchus and lung (18.93%).
Conclusion The course of pneumoconiosis had close relationships to the length of dust exposure and the stage of disease. Pneumoconiosis itself was the primary cause in the direct cause of death.
