This study retrospectively explored the late-life functional status of Okinawan centenarians.
Activities of daily living were measured retrospectively at five time points (10, 5, 3, and 1 year prior and present) for 22 centenarians in relation to seven physical, two sensory, and two cognitive functions using the Inoue Index.
In all, 82% of individuals were still functioning independently at a mean age of 92 years and almost two-thirds were still functioning independently at a mean age of 97 years.
Preliminary analyses suggest high functional status in Okinawan centenarians throughout their 90 s. The genetic and environmental factors contributing to this successful aging phenomenon deserve further investigation.
本研究回顾性地探究了冲绳百岁老人的晚年功能状态。
使用井上指数，对22位百岁老人在五个时间点（提前10年、5年、3年、1年以及当前）的日常生活活动进行回顾性测量，涉及七种身体功能、两种感官功能和两种认知功能。
总体而言，82%的个体在平均年龄92岁时仍能独立生活，近三分之二的个体在平均年龄97岁时仍能独立生活。
初步分析表明，冲绳百岁老人在整个90多岁时功能状态良好。导致这种成功衰老现象的遗传和环境因素值得进一步研究。
