喫煙とパーキンソン病

喫煙するとパーキンソン病になりにくいそうです。「タバコは百害あって一利なし」とか言う医者がいたら、「いやー、一利はあります」と反論しましょう。

Results We confirmed inverse associations between PD and smoking and found these to be generally stronger in current compared with former smokers; the associations were stronger in cohort than in case-control studies. We observed inverse trends with pack-years smoked at every age at onset except the very elderly (>75 years of age), and the reduction of risk lessened with years since quitting smoking. The risk reductions we observed for white and Asian patients were not seen in Hispanic and African American patients. We also found an inverse association both for smoking cigars and/or pipes and for chewing tobacco in male subjects.
