摘要
目的探讨补充抗氧化维生素与阿尔茨海默病的关系。方法全面检索到2009年12月为止的PubMed及其他科学网站的所有相关文献,应用Meta分析的方法对各研究进行数据合并和分析。结果纳入的文章共有6篇:队列研究3篇,随访人数累计7625例,病例622例;病例对照研究3篇,对照人数累计15 747例,病例973例。队列研究中,补充维生素C(Vc)、维生素E(Ve)和联合补充Vc+Ve的合并统计参数RR值分别为0.79(95%CI:0.55~1.12)、0.94(95%CI:0.73~1.22)和1.00(95%CI:0.77~1.29)。病例对照研究中,补充Vc、Ve以及Vc+Ve的合并统计参数OR值分别为1.50(95%CI:0.70~3.21)、1.06(95%CI:0.41~2.75)和1.81(95%CI:0.91~2.75)。结论补充抗氧化维生素不能降低阿尔茨海默病的发病。
