[A cohort study on the relationship between the mortality of cerebro-vascular diseases and farmer smokers].
The relationship between the mortality of cerebro-vascular diseases and farmer smokers in Shifang County was studied. The results indicated that the mortality of cerebro-vascular diseases in the male groups of cigarette-smokers older than 65 and cigar-smokers older than 55 was significantly higher than that of the nonsmokers (P < 0.05), the RR being 1.68-3.22. Also, the mortality in the female groups of cigarette-smokers older than 55 and cigar-smokers older than 65 was significantly higher than that of the non-smokers (P < 0.05), the RR being 1.99-3.19. The sex-specific mortalities of the other age groups revealed no significant differences in spite of some inequalities in smoking (P < 0.05). Age should be one of the risk factors for the death of cerebro-vascular diseases regardless of the sex. The mortality rose with the increasing accumulated amount of smoking. The relationship was not significant between the mortality of cerebro-vascular diseases and short-term smokers with small dose (P > 0.05). However, when the accumulated amount reached certain degree, i.e. the smoker consumed cigar more than 270 kg or consumed cigarette more than 10,000 packs, the relationship between the behavior of cigar-smoking and cigarette-smoking and the mortality became apparent, the RR being 2.53-3.91 (P < 0.01).
