目的了解煤工尘肺(CWP)患者死亡年龄与经济发展水平的关系以及死因的变动情况,进一步做好CWP的预防和管理工作。方法对868例CWP患者的死亡年龄和死因按改革开放前后(1955—2004年)2个阶段的资料进行统计对比分析。结果后25年死亡CWP患者的预期寿命延长,前24年肺结核咯血居死因第1位,后25年肺结核咯血居死因第7位;后25年肺心病居死因第1位,且脑血管病和恶性肿瘤在死因中呈明显上升态势。结论 CWP患者死亡年龄与经济发展水平呈正相关,CWP患者的死因顺序不同于非尘肺患者。
Objective To understand the relationship between the death age and the level of economic development in coal worker’s pneumoconiosis (CWP) patients and the changes of the cause of death, so as to further improve the prevention and management of CWP. Methods The age and cause of death of 868 CWP patients were statistically analyzed according to the data of two stages before and after the reform and opening up (1955-2004). Results The life expectancy of 25-year-old CWP patients was prolonged. In the first 24 years, the first place of pulmonary tuberculosis was hemoptysis, the seventh place of pulmonary tuberculosis in 25 years. The second place of death was pulmonary heart disease in 25 years. Cerebrovascular disease and Malignant tumors showed a clear upward trend in the cause of death. Conclusion The age of death in CWP patients is positively correlated with the level of economic development. The order of cause of death in CWP patients is different from that in non-pneumoconiosis patients.
