目的：探讨和比较4种体能指标对居家日本老年人功能依赖发生的预测价值。设计：以人群为基础的前瞻性队列研究。研究地点：日本秋田县南盖村。方法：1992年，在日本秋田县南盖村(n=940)，对736名能够独立进行5项基本生活活动的老年人进行握力、单腿站立、平时和最大步行速度的测量。在接下来的6年里，每年评估他们的功能状态。结果：即使在控制了年龄、性别和一些慢性疾病后，在每个基线绩效指标上得分较低的受试者也会增加发生功能性依赖的风险。对于65-74岁的老年人，最大步行速度对预测未来依赖最为敏感，而对于大于或等于75岁的老年人，平时步行速度最敏感。结论：在日本农村老年人口中，步行速度是预测功能依赖开始的最佳体能指标。
Objective: to investigate and compare the predictive values of four physical performance measures for the onset of functional dependence in older Japanese people living at home.Design: a population-based prospective cohort study.Setting: Nangai village, Akita Prefecture, Japan.Methods: out of the population aged 65 years and older living in Nangai (n = 940) in 1992, we measured hand grip-strength, one-leg standing, and usual and maximum walking speeds in 736 subjects who were independent in the five basic activities of daily living. Their functional status was assessed each year for the subsequent 6 years. The outcome event was the onset of functional dependence, defined as a new disability in one or more of the five basic activities of daily living, or death of a subject who had shown no disability at the previous follow-up.Results: even after controlling for age, sex and a number of chronic conditions, lower scores on each baseline performance measure showed increased risk for the onset of functional dependence. Maximum walking speed was most sensitive in predicting future dependence for those aged 65-74 years, while usual walking speed was most sensitive for people aged greater than or equal to 75 years.Conclusion: walking speed was the best physical performance measure for predicting the onset of functional dependence in a Japanese rural older population.
