背景和目标：比较身体功能的预测能力评估问卷调查和身体表现的措施，随后在社区居住的老年人disability。参与者为813名70岁及以上的日本老年人，他们居住在社区，包括在鹤谷项目中，在2003年基线时没有残疾。采用“运动适能量表”进行身体机能评定。体能测量包括最大步行速度、计时起立行走测试（TUG）、腿部伸展功率和功能性前伸测试。残疾受试者工作特征曲线的曲线下面积（AUC）用于比较运动体能量表和体能测量之间的筛选准确性。事件残疾，定义为长期护理保险认证，被用作endpoint.Results：我们观察到135例事件残疾在后续。与最高的四分位数相比，每项措施的第三和第四个四分位数与残疾风险显著增加相关。AUC分别为0.70、0.72、0.70、0.68、0.69和0.74，分别用于运动适应性量表、最大步行速度、牵引力、下肢伸展力、功能性前伸试验和总成绩scores.Conclusions：运动适应性量表评估的身体功能预测能力等同于身体成绩测量。运动适能量表较体能测验更能安全、简便地评估身体功能，是一种筛选残疾高危人群的实用工具。
BACKGROUND AND AIMS: To compare the predictive power of physical function assessed by questionnaire and physical performance measures for subsequent disability in community-dwelling elderly persons.METHODS: Prospective cohort study. Participants were 813 aged 70 years and older, elderly Japanese residing in the community, included in the Tsurugaya Project, who were not disabled at the baseline in 2003. Physical function was assessed by the questionnaire of "Motor Fitness Scale". Physical performance measures consisted of maximum walking velocity, timed up and go test (TUG), leg extension power, and functional reach test. The area under the curve (AUC) of the receiver operating characteristic curve for disability was used to compare screening accuracy between Motor Fitness Scale and physical performance measures. Incident disability, defined as certification for long-term care insurance, was used as the endpoint.RESULTS: We observed 135 cases of incident disability during follow-up. The third or fourth quartile for each measure was associated with a significantly increased risk of disability in comparison with the highest quartile. The AUC was 0.70, 0.72, 0.70, 0.68, 0.69 and 0.74, for Motor Fitness Scale, maxi- mum walking velocity, TUG, leg extension power, functional reach test, and total performance score, respectively.CONCLUSIONS: The predictive power of physical function assessed by the Motor Fitness Scale was equivalent to that assessed by physical performance measures. Since Motor Fitness Scale can evaluate physical function safely and simply in comparison with physical performance tests, it would be a practical tool for screening persons at high risk of disability.
