Cohort study on successful aging in a community-elderly

本研究的目的是探讨65岁时的生活方式、环境、体力活动和免疫活动对70岁时死亡率和发病率的影响。基线调查于1996年至2005年在N市进行，结果构建了3098人的65岁队列。流行病学资料采用自填式问卷调查，包括人口学资料、既往病史、食物摄入频率、吸烟和饮酒情况等。此外，还记录了人体测量和临床结果。随访方法有：1)对居住在N市的70岁老人进行医学体检，2)对未体检的老人进行个人探访，目前仍在继续。将基线数据与国民营养调查中显示的一般日本人的数据进行比较等，虽然我们队列中的受试者看起来更健康一些，但总体上没有显著差异。从这项研究中，一定会获得日本成功老龄化的有用证据。
