摘　　要：目的研究中国老年人步速现状及慢步速的影响因素。方法选取2015年“中国健康与养老追踪调查(CHARLS)”数据库中年龄≥60岁、进行过步速测量、基本数据无缺失的老年人为研究对象。比较不同人口学特征研究对象的步速差异,使用多因素logistic回归分析老年人慢步速的影响因素。结果本研究共纳入研究对象7267例,其中男性3615例,女性3652例;研究对象总人群的平均步速为(0.76±0.22)m/s;多因素logistic回归分析结果显示:年龄(OR 70~79岁=2.26、OR≥80岁=6.34);女性(OR=1.50);文化程度(OR_(小学)=0.76、OR_(初中)=0.55、OR_(高中及以上)=0.47);肥胖(OR=1.43);疾病史(OR_(高血压)=1.28、OR_(慢性肺部疾病)=1.34、OR_(症状性膝骨关节炎)=1.18)是老年人慢步速的影响因素(均P<0.05)。结论中国老年人平均步速为(0.76±0.22)m/s,高龄、女性、文化程度较低、肥胖、既往患高血压、慢性肺部疾病、症状性膝骨关节炎是我国老年人慢步速的影响因素。Objective To explore the status of gait speed and determinants of slow gait speed in Chinese elderly population.Methods Elderly population aged 60 and older who has been measured gait speed and without missing basic information data were selected from the data of China Health and Retirement Longitudinal Study(CHARLS)in 2015.The differences of gait speed among groups for different demographic characteristics were compared and multivariate logistic regression analysis were performed to explore determinants for slow gait speed.Results A total of 7267 subjects(3615 males and 3652 females)were included in the analysis and the average gait speed was(0.76±0.22)m/s.Multivariate logistic regression analysis showed that age(OR_(700-0F79years)=2.26,OR≥80years=6.34),female(OR=1.50),education level(OR primary school=0.76,OR_(middle school)=0.55,OR high school or above=0.47),obesity(OR=1.43),disease history(OR_(hypertension)=1.28,OR_(chronic lung diseases)=1.34,OR symptomatic keen osteoarthritis=1.18 were determinants of slow gait speed(all P<0.05).Conclusion The average gait speed was(0.76±0.22)m/s and older age,female,lower education level,obesity,hypertension or chronic lung diseases or symptomatic keen osteoarthritis are determinants in Chinese elderly population.
