摘要
目的探讨老年女性肌少症与平衡功能之间的相关性。方法 2017年9月至11月,招募60~70岁老年女性224例,根据肌容量、握力和6米步速分为正常组(n=198)和肌少症组(n=26)。比较两组闭眼单足站立时间和5次坐立试验时间;闭眼单足站立时间和5次坐立试验时间分别与肌容量、握力和6米步速行Pearson相关分析。结果老年女性肌容量、握力、6米步速单个指标异常率分别为20.5%、14.3%和2.2%,肌少症发生率11.6%。肌少症组闭眼单足站立时间显著短于正常组(t=4.072, P <0.001),5次坐立试验时间显著长于正常组(t=-5.461, P <0.001);正常组闭眼单足站立时间与6米步速明显正相关(r=0.675, P <0.01);肌少症组闭眼单足站立时间与6米步速(r=0.492)和握力(r=0.286)均显著正相关(P <0.001);两组5次坐立时间均与握力(r=0.351, r=0.462)、肌容量(r=0.258, r=0.321)、6米步速(r=0.337, r=0.396)显著正相关(P <0.001)。结论相对肌肉质量和力量而言,老年女性增龄过程中肌肉功能保持相对较好。患肌少症的老年女性动静态平衡功能均下降。静态平衡主要与肌肉功能关系较大,动态平衡与肌肉质量、力量和功能均有关联。
Objective To explore the correlation between sarcopenia and balance in old women.Methods From September to November,2017,224 women aged 60 to 70 were recruited.They were divided into normal group(n=198)and sarcopenia group(n=26)according to the results of muscle volume,grip strength and 6-meter walking speed(6MWS),and tested with single foot standing with eyes close(SSEC)and the five times of sitto-stand(5STS).The correlation of the time of SSEC and 5STS to muscle volume,grip strength and 6MWS were analyzed with Pearson's Correlation Analysis in both groups,respectively.Results The incidence of simple decrease in muscle volume,grip strength and 6MWS was 20.5%,14.3%and 2.2%,respectively,and the incidence of sarcopenia was 11.6%.The time of SSEC was shorter in the sarcopenia group than in the normal group(t=4.072,P<0.001),and the time of 5STS was longer(t=-5.461,P<0.001).The time of SSEC correlated with 6MWS in normal group(r=0.675,P<0.01),and it correlated with 6MWS(r=0.492)and grip strength(r=0.286)in the sarcopenia group(P<0.001).The time of 5STS correlated with muscle volume(r=0.258,r=0.321),grip strength(r=0.351,r=0.462)and 6MWS(r=0.337,r=0.396)in both groups(P<0.001).Conclusion Compared with muscle mass and strength,the muscle activities remain well in the old women in the process of aging.Both static and dynamic balance reduce in the old women with sarcopenia.The static balance mainly relates with muscle activities,while the dynamic balance relates with all the muscle mass,strength and activities.
