Cohort study on successful aging in a community-elderly

本研究的目的是调查 65 岁时的生活方式、环境、身体和免疫活动如何影响 70 岁时的死亡率和发病率。 1996年至2005年在N市进行了基线调查，构建了3098人的65岁队列。通过自填问卷收集流行病学信息，如人口统计信息、既往病史、食物摄入频率、吸烟和饮酒状况等。还记录了人体测量和临床结果。随访方式为1）对居住在N市的70岁老人进行体检，2）对未进行体检的人进行个别访视，目前仍在继续。与全国营养调查等显示的日本一般人的基线数据相比，虽然我们队列中的受试者看起来更健康一些，但总体上没有显着差异。从这项研究中，肯定会获得日本成功老龄化的有用证据。
