摘    要:目的 研究北京市城区居民烟草消费和大气污染对肺癌死亡率的影响,为相关政策制订提供依据.方法 收集1982-2005年北京市城区居民肺癌死亡率、居民年人均烟草消费和大气污染资料,进行趋势分析,采用Eviews软件拟合烟草消费和大气污染与肺癌死亡率关系的分布滞后模型,根据模型分析烟草消费和大气污染对肺癌死亡率的影响.结果 北京市城区居民肺癌死亡率呈上升趋势,从1982年的19.74/10 万上升到2005年的44.73/10万;构建烟草消费和大气污染与肺癌死亡率关系的分布滞后模型,当大气污染选择综合污染指数、NO_2和PM10时无统计学意义,仅SO_2有统计学意义(P<0.05);构建的模型以肺癌死亡率为因变量,烟草消费和SO_2为自变量,调整决定系数(R)~2=0.78时,烟草消费对肺癌死亡率影响的滞后期为8 a,SO_2对肺癌死亡率影响的滞后期为7a.结论 北京市城区肺癌死亡率呈上升趋势,烟草消费和大气污染均对肺癌的死亡率有影响,烟草消费和SO_2对肺癌死亡率影响分别有8a和7a的滞后期.

关 键 词:空气污染  肺癌死亡率  烟草消费  分布滞后模型

Influence of Tobacco Consumption and Air Pollution on Lung Cancer Mortality of Permanent Residents in Beijing Urban Area
Abstract:Objective To understand the trend of lung cancer mortality of permanent residents in Beijing urban area caused by the influence of per capita tobacco consumption and air pollution.Methods Data of lung cancer mortality,air pollution and tobacco consumption from 1982 to 2005 was collected from published year books and Beijing cancer registration division.Trend analysis was applied to test significance of trend of lung cancer mortality of permanent resident in Beijing urban area.Distributed lag model was applied to determine the influence of per capita tobacco consumption and air pollution on lung cancer mortality by Eviews software package.Results Lung cancer mortality of permanent residents in Beijing urban area elevated from 19.74/100 000 in 1982 to 44.73/100 000 in 2005.In the distributed lag model for lung cancer mortality,with per capita tobacco consumption as independent variable,comprehensive index of air pollution,NO_2 and PM10 were not statistical significant,while SO_2 had statistical significance(P<0.05).In the model constructed for lung cancer,mortality of lung cancer was dependent variable,per capita tobacco consumption and SO_2 were independent variable,the adjusted determination coefficient ((R)~2)was 0.78.The effect of tobacco consumption on lung cancer mortality had a lag period of 8 years,and as for SO_2,a lag period of 7 years.Conclusion Lung cancer mortality rate of permanent resident in Beijing urban area is increasing.Both tobacco consumption and air pollution are the factors affecting the lung cancer mortality.The tobacco consumption has the lag effect of 8 years,and SO_2 concentration has the lag effect of 7 years to the lung cancer mortality in Beijing urban area.
Keywords:Air pollution  Mortality rate of lung cancer  Tobacco consumption  Distributed lag model
