某公司无矽肺人员与矽肺患者死亡情况的对比分析

Comparison of the causes between deaths due to non-silicosis and silicosis in a company

目的探讨矽肺病的发展及其转归,对比退休人员中无矽肺人员与矽肺患者的死亡同异。方法选取1994-2012年浙江东风莹石集团有限公司退休职工1718人,分为无矽肺人员与矽肺病患者两组,两组累计死亡545例,就两组死亡率和平均死亡年龄以及主要死因归类等指标进行回顾性对比分析。结果两组的死亡率和死亡年龄均呈缓慢上升趋势,但矽肺病患者的死亡率上升更为明显,死亡年龄差异无统计学意义(P>0.05)。主要死因归类:无矽肺人员以恶性肿瘤居首,矽肺患者以呼吸疾病为首。结论矽肺患者本身肺部病变是导致死亡的首要因素。结果验证了二三级预防工作的效果,对今后的防治工作具有指导意义。

Objective To explore the progress of silicosis and its outcome, and compare difference of deaths from non--silicosis and silicosis. Methods 1718 retired workers in Zhejiang Dongfeng Fluorite Group Co. Ltd. were selected during the period between 1994 and 2012, and divided into non--silicosis group and sili- cosis patients group. The mortality rate, average death age and main cause of death were analyzed for the two groups. Results Totally there were 545 deaths. The mortality and death age in these two groups increased slowly with ages. The mortality from silicosis increased more significantly, but the death age were not statisti- cally significant （P-0. （）5）. The leading cause of deaths was malignancy for no--silicosis 1 group, and respira- tory diseases for silicosis. Conclusions Lung disease related to silicosis is the leading cause of deaths. The study demonstrates the effect from secondary and tertiary preventions, which will provide guidance for the future work of prevention and control of silicosis.
