摘要
目的:分析吸烟与我国城市男性居民膀胱癌死亡率的关系。方法:选取1986-01-01-1988-12-31全国人口死因与吸烟情况的调查资料,根据各市膀胱癌患者死亡数量,选择例数较多的22个城市35～69岁男性患者死者的资料进行吸烟与膀胱癌死亡率关系的分析。结果:22个城市35～69岁男性在1986-1988年的膀胱癌死亡率为1.85～8.89/10万。20岁前开始吸烟、累计吸烟年限≥40年与35～69岁膀胱癌的死亡率呈正相关,r值分别为0.55和0.59,P值分别为0.008和0.004;60～69岁者生前吸烟与该年龄组的膀胱癌死亡率呈正相关,r=0.46,P=0.03。结论:中国城市男性开始吸烟的年龄、累计吸烟年限和生前吸烟是膀胱癌的重要危险因素。
OBJECTIVE： To examine the association between smoking and bladder cancer mortality in males of China. METHODS： Using the national census data on causes of death and smoking between 1 January 1986 and 31 December 1988,and the data of 35 to 69 year-old men were selected, who died of bladder cancer, in 22 cities with adequate dead of bladder cancer to an- alyze the correlation coefficient between mortality rates of bladder cancer and the smoking proportion of dead. RESULTS： From 1986 to 1988,mortality rates of bladder cancer were from 1.85/100 000 to 8.89/100 000 in 35 to 69 year-old men in 22 cities of China. The proportions of smokers who started smoking in ages less than 20 years, the cumulated years of smoking for 40 years or over were found significantly positive correlated with the mortality rates of bladder cancer, with correlation coefficients were at 0. 55 （P=0. 008） and 0.59 （P=0. 004） ,respectively. Mortality rates of bladder cancer in ages of 60 to 69 years in men were sig- nificantly positive correlated with the proportion of male smokers dead from bladder cancer, are r~ 0. 46, P = 0.03. CONCLU- SION .. The age to start smoking, the cumulative years of smoking as well as smoking are important risk factors to develop bladder cancer in male population in urban China.
