Data analysis of occupational health examination of coal mine workers before dimission

Objective To understand the health status of coal workers who were going to leave their jobs, and to provide scientific basis for disease prevention and control for them.

Methods The data of 1 521 coal mine workers' occupational health examination were analyzed.

Results Totally 101 cases (6.64%)were diagnosed as the suspected pneumoconiosis, while prevalence of male workers was higher than that of female workers(P < 0.05). It was noted that the elder workers, the workers engaged in coal cutting and the workers employed more than 10 years but less than 20 years, had higher prevalences of suspected pneumoconiosis (P < 0.01). It seemed that the workers diagnosed as suspected pneumoconiosis had lower abnormality of blood pressure and ECG(P < 0.05).

Conclusion It is critical to give more attention to the coal-getter. We should pay attention to prevention of cardiovascular diseases of all workers, while strengthening the prevention and control of pneumoconiosis.
