The association between gait speed, a vital health outcome in older adults, and health literacy, an important health promotion aspect, is unclear. This study examined the relationship of gait speed with health literacy, physical function, and cognitive function in community-dwelling older adults. The subjects were 240 older adults (52 men, mean age 73.8 ± 6.0 years). Gender, age, and education were self-reported, while height and weight were measured directly. Health literacy was evaluated using Communicative and Critical Health Literacy (CCHL). Grip strength, knee extension strength, toe-grip strength, sit-up test, sit-and-reach test, one-leg stance test time, 30-s chair-stand test (CS-30), and normal gait speed were measured. Subjects were divided into two groups based on normal gait speed-fast (speed ≥ 1.3 m/s) and slow (<1.3 m/s). In the logistic regression analysis, the dependent variable was normal gait speed (fast/slow). Four logistic regression models were utilized to determine whether health literacy affects gait speed. Height and CCHL were found to independently affect gait speed. That health literacy influences gait speed is a new discovery.
步态速度（老年人一项重要的健康指标）与健康素养（健康促进的一个重要方面）之间的关联尚不清楚。本研究调查了社区居住的老年人中步态速度与健康素养、身体功能和认知功能之间的关系。研究对象为240名老年人（52名男性，平均年龄73.8±6.0岁）。性别、年龄和教育程度通过自我报告获取，身高和体重则直接测量。使用沟通与批判性健康素养（CCHL）评估健康素养。测量握力、膝关节伸展力量、脚趾抓握力、仰卧起坐测试、坐位体前屈测试、单腿站立测试时间、30秒椅子站立测试（CS - 30）以及正常步态速度。根据正常步态速度将受试者分为两组——快速组（速度≥1.3米/秒）和慢速组（<1.3米/秒）。在逻辑回归分析中，因变量为正常步态速度（快速/慢速）。使用四个逻辑回归模型来确定健康素养是否影响步态速度。结果发现身高和CCHL能独立影响步态速度。健康素养会影响步态速度这一发现是全新的。
