云南锡业矿工肺癌死亡相关因素分析

近年来的研究表明，云南锡业公司矿工的肺癌发生率和死亡率均高于一般人群，肺癌已成为严重危害工人健康的疾病。已往的研究表明肺癌的发生与矿工的职业暴露有较强的相关，但有关肺癌死亡与职业暴露等因素的研究国内外报道甚少，本文从云锡公司矿工的死亡状况的分析来探讨一下作业过程中劳动条件与肺癌死亡之间的联系，并对因肺癌而导致的减寿年数进行计算和分析。结果表明，高危人群列死因顺位首位的疾病为恶性肿瘤，占死因构成的３４．６８％ ，其死亡率为４０７．４９／１０ 万；肺癌死亡者占恶性肿瘤死亡者的７６．５０％ ，其死亡率为３１１．９０／１０ 万。经多因素Ｌｏｇｉｓｔｉｃ 分析，与肺癌死亡有关的因素有：慢性支气管炎、砷暴露和氡子体的暴露，其中氡子体的暴露又为最主要的相关因素。因肺癌导致的减寿年数为２６２ 人·ａ，平均减寿年数为４．８５ ａ。故开展肺癌的防护对保护职业人群的健康具重要意义。

The recent years' study showed the incidence rate and mortality rate of lung cancer of YTC's workers were higher than usual population,lung cancer had turned a serious disease affected workers'health.We analysed the relating factors of mortality and calculate PYLL of lung cancer.The results indicated that the disease of the highest mortality rate was lung cancer,the proportion dying of cancer was 36.49%,and its mortality rate was 407.49/10,0000.The determinants were selected by logistic regression analysis.It was shown that the dying of lung cancer was affected by chronic bronchitis,arsenic exposure and radon progeny exposure.The PYLL of lung cancer was 262,the AYLL was 4.85.The professional prevention of lung cancer could protect the workers health,decline the mortality of lung cancer.
