摘　　要：目的研究吸烟与中国城乡居民肺癌死亡关系。方法分析全国103个市（县）人口死因、死亡者及对照的吸烟资料，分层计算35岁以上男女性城乡各年龄组因吸烟增加的肺癌死亡风险、超额死亡及其损失的平均期望寿命。结果对1986—1988年间中国52193例肺癌死亡者和307934例对照的资料分析显示，与非吸烟者相比，城市和农村男女性35岁以上各年龄组吸烟者的肺癌死亡风险均显著增高；男性吸烟者死于肺癌的相对风险为3．0（95％CI：2．9～3．1），超额死亡为53．0％，城乡35～69岁因吸烟死于肺癌损失的期望寿命平均分别为18．5年和17．7年；女性吸烟者死于肺癌的相对风险为3．0（95％CI：2．9～3．1），超额死亡为26．0％，城乡35～69岁因吸烟死于肺癌损失的期望寿命平均分别为13．0年和20．4年。结论吸烟增加城乡35岁以上男女性各年龄组肺癌死亡风险及使预期寿命的严重损失。全面控制人群吸烟率将对减少城乡居民的肺癌死亡风险有重要意义。Objective To study the association between smoking and lung cancer mortality of residents living in the urban and rural areas of China. Methods Using the national census data on causes of death and case-control studies, stratified analysis was conducted by parameters as geography and age, to calculate the risk ratios, excess risks, average years lost for life expectancy by smoking in males and females in 103 cities/counties in China. Results Smoking increased the risks for lung cancer death in all ages older than 35 years of age, in urban and rural areas, through data analysis on 52 193 cases died from lung cancer in 1986- 1988 and 307 934 matched controls in China. The risk ratio was 3.0 （95%CI： 2.9-3.1 ） with 53.0% excess for lung cancer deaths in the male smokers. The years lost for life expectancy were 18.5 in urban, and 17.7 in rural male smokers aged 35 to 69 years. Similarly, the risk ratio was 3,0 （95%CI： 2.9-3.1 ）, with 26.0% excess for lung cancer deaths in female smokers. The life-expectancy lost was 13.0 and 20.4 for female smokers aged 35 to 69 years in urban and rural areas, respectively. Conclusion In both urban and rural areas, risk on lung cancer deaths caused by smoking in all males and females aged at 35 years and older had been significantly increased. Control of smoking prevalence should play a vital role in the prevention of the lung cancer death risks in China.
