2型糖尿病患者踝肱指数与行走能力的相关性分析

Relationship between Ankle-Brachial Index and Walking Ability in Type 2 Diabetic Patients

目的探讨2型糖尿病患者踝肱指数（ankle-brachial index,ABI）与其行走能力之间的相关性。方法纳入2型糖尿病患者196例,要求所有患者完成中文版行走受损问卷与6 min行走距离,并测量ABI。将研究对象按ABI值分为3组（ABI〈0.7,ABI 0.7~〈0.9,ABI 0.9-1.3,进行方差分析及Spearman相关分析。结果不同ABI组间行走能力各评分及6 min行走距离的差异有统计学意义;ABI与6 min行走距离、行走能力呈正相关（P〈0.01）。结论2型糖尿病患者踝肱指数与其行走能力关系密切,2型糖尿病患者踝肱指数越低,6 min行走距离越短,行走相关性能力也越低。在临床工作中,可用踝肱指数来评估2型糖尿病患者的行走能力。

Objective To explore the relationship between Ankle-brachial Index （ABI） and walking ability in Type 2 diabetic patients. Methods One hundred and ninety-six subjects with type 2 diabetic mellitus were cross-sectionally studied. Subjects were divided into three groups according to the value of ABI （ABI〈0.7, ABI 0.7-0.9, ABI 0.9-1.3）. The Chinese version of Walking Impairment Questionnaire （WIQ）, Six-minute walk test （6MWT） were used to collect data that was conducted for statistical analysis, including Spearman correlation and analysis of eovarianee. Results Lower ABI corresponds with shorter Six-minute walk distance （6MWD）, lower scores of WIQ （P〈0.01）. ABI was significantly associated with WIQ and 6MWD （P〈0.01）. Conclusion Ankle- brachial index （ABI） is significantly associated with walking ability in type 2 diabetic patients. In general practice, clinicians can use the ABI to gauge walking ability among type 2 diabetic patients.
