摘　　要：目的探讨上臂围和小腿围与肌肉量的相关关系及其对肌量减少和肌少症的筛查诊断效果和最佳诊断截断值。方法2020年3月至8月,方便抽取831例社区老年人(≥60岁)作为研究对象,采用身体成分测试仪检测肌肉量等指标,同时进行上臂围和小腿围的测量,握力及步速测试。上臂围、小腿围与肌肉量等指标的相关性行Pearson相关分析,受试者操作特征(ROC)曲线分析上臂围和小腿围对肌量减少和肌少症的诊断效果,并利用约登指数(YI)确定最佳诊断截断值。结果上臂围和小腿围与四肢骨骼肌含量(ASM)和骨骼肌质量指数(SMI)呈显著正相关(r=0.6~0.8,P<0.001)。上臂围诊断肌量减少的ROC曲线下面积(AUC)是男性0.888、女性0.787,小腿围是男性0.933、女性0.854;上臂围最佳截断值男性和女性均为26 cm,小腿围男性34 cm、女性33 cm。上臂围诊断肌少症的AUC是男性0.902、女性0.744,小腿围是男性0.923、女性0.832;其最佳截断值无性别差异,分别是26 cm和33 cm。在社区老年男性和女性中,年龄、上臂围、小腿围、握力和步速等多指标对肌量减少和肌少症联合诊断的AUC均大于0.85。结论社区老年人中,上臂围和小腿围均与肌肉量呈正相关,且对肌量减少和肌少症具有较好的诊断效果;多指标的联合诊断可显著提高上臂围在女性中的诊断效果。Objective To explore the correlation of upper arm circumference and calf circumference with muscle mass,and the screening effect and the cut-off values for low muscle mass and sarcopenia.Methods From March to August,2020,a total of 831 community-dwelling old people(≥60 years old)were recruited by using convenience sampling.Muscle mass and other body composition indicators were tested by body composition tester.The upper arm circumference,calf circumference,grip strength and gait speed were measured at the same day.Pearson cofficient was used to analyze the correlation of upper arm circumference and calf circumference with muscle mass,and receiver operation characteristic(ROC)curve was used to analyze the diagnostic effect of upper arm circumference and calf circumference on low muscle mass and sarcopenia,and the Youden index(YI)was used to determine the cut-off values.Results Upper arm circumference and calf circumference were positively correlated with appendicular skeletal muscle mass(ASM)and skeletal mass index(SMI)(r=0.6 to 0.8,P<0.001).For diagnosing low muscle mass,the areas under the ROC curve(AUC)of upper arm circumference were 0.888 for male,0.787 for female;and that of calf circumference were 0.933 for male,0.854 for female,respectively.The cut-off values of upper arm circumference for low muscle mass were 26 cm for both male and female;and that of calf circumference were 34 cm for male and 33 cm for female, respectively. For diagnosing sarcopenia, the AUC of upper arm circumference was 0.902 for male, 0.744 for female;and that of calf circumference was 0.923 for male, 0.832 for female, respectively. The cut-off values of upper arm circumference and calf circumference for sarcopenia were 26 cm and 33 cm for both male and female. The AUC of combined diagnosis with age, upper arm circumference, calf circumference, grip strength and gait speed for low muscle mass and sarcopenia in males and females was all greater than 0.85. Conclusion In the community old adults, upper arm circumference and calf circumf
