To determine normative data for gait speed and height-normalized gait speed in community-dwelling older men and women.
In this cross-sectional study, we recruited 565 men and women aged ≥60 years old. Age was calculated from the date of birth and further classified into four categories: (1) 60-65 years, (2) 66-70 years, (3) 71-75 years and (4) ≥76 years. Gait speed was assessed by a pressure platform (ZEBRIS, Munich, Germany) in meters per second (m/s). Height and weight were objectively measured. Height-normalized gait speed was calculated by dividing gait speed by height. We created the 20th, 40th, 60th and 80th percentile curves for both outcome measures using Cole's Lambda (L), Mu (M) and Sigma (S) method.
Mean gait speed and height-normalized gait speed was 1.24 (standard deviation 0.28) and 0.75 (0.17). Significant age-related decline in gait speed for both sexes was observed ( < 0.001). Being a woman ( = - 0.09, < 0.001), being older ( = - 0.02, < 0.001) and having higher body mass index values ( = - 0.02, < 0.001) were significantly associated with slower gait speed.
Gait speed significantly declines with age in both older men and women. Providing normative data can be used in screening and monitoring "slow" walkers to prevent from foot pain and higher risk of falls.
确定社区居住的老年男性和女性的步速和身高标准化步速的正常值数据。
在这项横断面研究中，我们招募了 565 名年龄≥60 岁的男性和女性。年龄根据出生日期计算，并进一步分为四类：（1）60-65 岁，（2）66-70 岁，（3）71-75 岁和（4）≥76 岁。步速通过压力平台（德国慕尼黑 ZEBRIS）以米/秒（m/s）评估。身高和体重通过客观测量。身高标准化步速通过将步速除以身高计算得出。我们使用 Cole 的 Lambda（L）、Mu（M）和 Sigma（S）方法为两种结果测量值创建了第 20、40、60 和 80 百分位曲线。
平均步速和身高标准化步速分别为 1.24（标准差 0.28）和 0.75（0.17）。男女的步速均随年龄显著下降（<0.001）。女性（= - 0.09，<0.001）、年龄较大（= - 0.02，<0.001）和身体质量指数值较高（= - 0.02，<0.001）与较慢的步速显著相关。
男女老年人的步速均随年龄显著下降。提供正常值数据可用于筛选和监测“慢行者”，以预防足部疼痛和更高的跌倒风险。
