摘要
本文通过对辽宁省七城市703对(1:1)肺癌病例对照调查分析,揭示了北方城市吸烟在致肺癌病因中的作用强度及暴露危险,同时指出:北方人吸烟率高但其作用弱是一值得继续探讨的问题。
A case-control study involving 703 lung cancer deads and 703 control deads of causes other then lung cancer and respiratory diseases were conducted in seven cities of Liaoning. Smoking was found the predominant risk factor of lung cancer,accounting for 58% for males and 39% for females in terms of the population attributable fraction. Risk of smoking increased in proportion with the amount of smoking and the years of smoking, decreasing with the age of beginning and the years of ceasing smoking. Risk was close to zero after ten years of ceasing. Stop smoking would save 63 lives per hundred thousands for males and 44 lives for females per year.
