对35岁以上的农民29498人五年随访的结果表明:男性吸烟者中恶性肿瘤标化死亡率的RR吸香烟和晒烟者分别为1.82和1.75。35～49岁组RR最高;女性吸烟者中仅50～79岁组吸烟者RR大于1,动态范围是1.4～1.8。在不同肿瘤中,吸香烟者患肺癌的RR为1.82;男性吸香烟和吸晒烟者患胃癌的RR分别为2.89和2.71;男性吸晒烟者患肝癌的RR为1.70;女性吸晒烟者患食道癌的RR为2.27;其余恶性肿瘤标化死亡率的RR≤1。吸烟对恶性肿瘤死亡率的影响只有当吸烟的积累量达到一定程度时才能被发现。
The results of five-year follow-up of 29498 rural residents over the age of 35 showed that RR of smoked and smokers with RR of malignant tumor in male smokers were highest at RR of 1.82 and 1.75.35 to 49 years respectively; female smoker In only 50 to 79 years old group smoker RR greater than 1, the dynamic range of 1.4 to 1.8. In different cancers, the RR of smoking lung cancer patients was 1.82. The RR of gastric cancer patients smoking cigarettes and smoking cigarettes were 2.89 and 2.71 respectively. The RR of male patients with smoking sun cancer was 1.70. The RR of esophageal cancer was 2.27; RR of the standardized mortality of other malignancies was RR≤1. The effect of smoking on cancer mortality can only be detected when the cumulative amount of smoking reaches a certain level.
