Abstract:
Objective To analyze the epidemiological characteristics of pneumoconiosis from 1985 to 2006 in Xinjiang to provide the reference for decision-making of the further preventive measure.
Methods We carried out an epidemiological in vestigation on pneumoconiosis cases in Xinjiang.
Results In Xinjiang, the amount of pneumoconiosis cases accumulated to 3 687 from 1985 to 2006. Among those, 2 644 cases were in stage I, 841 in stage II and 202 in stage III. The top 5 types of pneumoconiosis were coal miners' pneumoconiosis, silicosis, cement pneumoconiosis, foundery workers' pneumoconiosis, and welders' pneumoconiosis, which accounted for 46.46%, 30.62%, 7.59%, 3.99%, and 2.63% respectively. The sum of coal miners' pneumoconiosis and silicosis cases was 2 842, accounting for 77.08%. Most of these cases occurred in workers chiefly working in coal mine, and then in foundery, cement manufacturing industry, and the others. Since 1985, coal miners' pneumoconiosis and silicosis consisted the main part of all pneumoconiosis cases, which accounted for 46.46% and 30.62% respectively. According to the logistic regression, age of the worker, working period and type of working were main factors which affecting pneumoconiosis.
Conclusion The top 5 kinds of pneumoconiosis consist of coal miners' pneumoconiosis, silicosis, cement pneumoconiosis, foundery workers' pneumoconiosis, and welders' pneumoconiosis. The complication rate of tuberculosis among pneumoconiosis patients was high. In Xinjiang, the control of pneumoconiosis and occupational health service still faces the challenge and needs to strengthen the management and supervision on all factories especially in poor areas for final elimination of the pneumoconiosis.
