法国研究人员于本周一称,与不吸烟者相比,中年吸烟者在记忆力和推理测试中的表现较差。这无疑是戒烟的又一个理由。
研究人员分析了之前收集的英国约五千名公务员的有关数据后发现,与从不吸烟者相比,吸烟者在记忆力、推理、词汇和口头表达等几项测试中表现居五组中最差的几率更大。
研究人员发现,吸烟会导致中年人智力水平下降,而且会导致日后老年痴呆及其它很多身体性疾病。
位于法国维勒瑞夫的全国健康与医疗研究所的瑟弗琳•萨比娅及其同事得出结论:“中年吸烟会导致记忆力减退和推理能力下降。”
萨比娅在发表于《内科医学档案》期刊上的研究报告中称,与吸烟者相比,称自己已戒烟的人更易养成更为健康的生活习惯,比如少喝酒、多锻炼,多吃水果和蔬菜。
这项研究刚开始时,研究对象的年龄在35岁至55岁之间,研究人员对其中一些人进行了长达17年的跟踪调查。
该研究还让人们了解到对吸烟者进行长期的跟踪调查有多么困难:拒绝再次接受记忆测试或者无法再次接受测试的吸烟者比不吸烟者多一倍以上,有些是因为研究对象在此期间已去世。
