[Prevalence of pneumoconiosis in a coal enterprise from 2002 to 2013].

Objective: To investigate the prevalence of pneumoconiosis in a coal enterprise, and to provide a basis for the prevention and treatment of pneumoconiosis. Methods: The workers' occupational health examination data were collected, and a cross-sectional study was performed to analyze the prevalence of pneumoconiosis. Results: A total of 62 976 person times of occupational health examination were performed for the workers exposed to dust in this enterprise from 2002 to 2013. There were 8 445 cases of pneumoconiosis diagnosed in total, and the mean detection rate was 13.41%. Of all patients with pneumoconiosis, 3 262 died. The mean detection rate was 8.98% among in-service workers and 19.64% among retired workers. The mean age of onset was (52.6±11.3) years, and the mean working age of onset was (18.4±10.1) years. Conclusion: The detection rate of pneumoconiosis is high in the retired workers in this enterprise, and medical follow-up for retired workers and those who have left their jobs should be taken seriously.
