This study was conducted to find an optimal questionnaire to evaluate the slow gait speed seen in community dwelling elderly.
Four questions asking about difficulty in walking were compared against the measured usual gait speed. The questions were: 1) Is it difficult to walk 100 m without help? 2) Is it difficult to walk 300 m without help? 3) Is it difficult to walk around one lap of a 400-meter track without help? 4) Can you cross a crosswalk before the green on the crosswalk light turns red?
The subjects were 1479 older adults aged 70 to 84 years who had responded to the four questions and completed gait speed measuring in the first baseline year (2016) of the Korean Frailty and Aging Cohort Study.
Of the four questions, "Is it difficult to walk around one lap of track (400 m) without help?" showed the highest kappa coefficient (0.357), sensitivity (0.61), and negative predictive value (0.82).
Based on the results of this study, the authors suggest that "Difficulty in walking around one lap of a 400-m track without help" may be the best question to use when evaluating slow gait speed.
本研究旨在寻找一种评估社区居住老年人慢步速的最佳问卷。
比较了四个询问步行困难的问题与实测的通常步行速度。这些问题是：1）在没有帮助的情况下走 100 米是否困难？2）在没有帮助的情况下走 300 米是否困难？3）在没有帮助的情况下走 400 米跑道一圈是否困难？4）您能否在人行横道绿灯变红之前穿过人行横道？
本研究的对象是 1479 名年龄在 70 至 84 岁之间的老年人，他们在韩国虚弱和衰老队列研究的第一个基线年（2016 年）回答了这四个问题并完成了步态速度测量。
在这四个问题中，“在没有帮助的情况下走 400 米一圈是否困难？”显示出最高的kappa 系数（0.357）、敏感性（0.61）和阴性预测值（0.82）。
基于这项研究的结果，作者建议，“在没有帮助的情况下走 400 米一圈是否困难”可能是评估慢步速时使用的最佳问题。
