摘要
目的:评价体重指数(BMI)作为筛检老年人肌肉衰减综合征指标的应用价值。方法:参照肌肉衰减综合征亚洲工作组制定的诊断标准对郑州市上街区1 287例60岁以上汉族老年人进行肌肉衰减综合征的临床诊断,并依此分为患病组和未患病组。使用受试者工作特征(ROC)曲线对BMI诊断郑州市上街区汉族老年人肌肉衰减综合征的价值进行评价。结果:未患病组老年男、女的BMI值分别为(25.94±3.10)和(26.44±3.43)kg/m2,患病组老年男、女的BMI值分别为(22.06±2.56)和(22.74±2.77)kg/m2。患病组老年人的BMI明显低于未患病组(P<0.001)。BMI用于诊断老年男、女肌肉衰减综合征的ROC曲线下面积(AUC)分别为0.834(0.769~0.899)和0.804(0.757~0.850),此时的灵敏度和特异度分别为73.2%、82.2%和78.2%、73.1%,对应的切点值则分别为23.0、24.3 kg/m2。结论:BMI测量简单易行,可以用于汉族老年人肌肉衰减综合征的快速筛检。
Aim： To evaluate the application value of body mass index（ BMI） for sarcopenia screening in the elder people. Methods： According to the diagnostic criteria of Asian Working Group for Sarcopenia,a total of 1 287 adults of Han nationality aged over 60 years in a community of Shangjie,District,Zhengzhou City,were screened for sarcopenia.The height and weight were measured to calculate the value of BMI. Receiver operator characteristic curve（ ROC） was used to evaluate the value of BMI for sarcopenia screening in the elder people. Results： The BMI values of the elderly male and female in the patients group was（ 22. 06 ± 2. 56） and（ 22. 74 ± 2. 7） kg / m2,respectively. It was（ 25. 94 ± 3. 10） and（ 26. 44 ± 3. 43） kg/m2 in contrast group,respectively. And the value of BMI in the patients group was lower than that of contrast group（ P 0. 001）. The ROC curve analysis results showed that AUC of sarcopenia in male and female was 0. 834（ 0. 769- 0. 899） and 0. 804（ 0. 757- 0. 850）,respectively. The sensitivity and specificity of BMI were 73. 2%,82. 2%in male and 78. 2%,73. 1% in female,with their corresponding cut-off value of 23. 0 and 24. 3 kg / m2. Conclusion： The measurement of BMI is simple and easy. The value of BMI can be used to screen sarcopenia in elder adults of Han nationality.
