对 130 0 0名成年男性进行 10年的吸烟与相关死因前瞻性调查 ,发现吸烟人群 10年中全死因死亡率为 119 12‰ ,不吸烟人群为 93 49‰。吸烟与慢性支气管炎死因的RR为2 0 4,与肺癌死因的RR为 3 0 3 ,与脑出血死因的RR为 1 34,与脑血栓死因的RR为 2 12。追踪至 1999年底 ,吸烟人群比不吸烟人群的平均生存年龄减少了 2 7年 ,重度吸烟比中度吸烟的平均生存年龄减少了 0 91年。中度吸烟比轻度吸烟的平均生存年龄减少了 0 .6年。 2 0岁以前开始吸烟比 2 0岁以后开始吸烟的平均生存年龄减少了 2 38年
A prospective 10-year study on smoking and related causes of death among 130 0 adult males found that the 10-year population-based death rate for smokers was 119 12 ‰ and 93 49 ‰ for non-smokers. The RR of death from smoking and chronic bronchitis was 204, RR of death from lung cancer was 330, RR of death from cerebral hemorrhage was 1 34, and RR of death from cerebral thrombosis was 2 12. Tracing to the end of 1999, the average age at death of smokers was 27 years less than that of non-smokers, and the average age at which severe smokers were smokers was 91 years lower than that of moderate smokers. Moderate smoking was 0.6 years less than the average age at mild smoking. Smoking started before the age of 20 reduced by 2 38 years compared with the average age at which people started to smoke after the age of 20
