Abstract

Background: The aim of this study is to determine cutoff values for different appendicular skeletal muscle mass index (ASMI) methods measured by dual-energy x-ray absorptiometry (DXA) in a reference group of the Turkish population.

Methods: Body composition analyses were performed with DXA, and appendicular skeletal muscle mass (ASM) was adjusted to body size as ASMI using height squared (ASM/ht²), weight (ASM/wt), and body mass index (BMI) (ASM/BMI). Sex-specific cutoff values were obtained as 1 and 2 standard deviations (SDs) below the mean values of ASM/ht², ASM/wt, and ASM/BMI.

Results: A total of 207 (106 women and 101 men) healthy adults were enrolled. Sex-specific cutoff values based on 1 SD below the mean values of ASM, ASM/ht², ASM/BMI, and ASM/wt were 14.44, 5.45, 0.61, and 24.07 in women and 22.63, 7.22, 0.90, and 29.04 in men, respectively; 2 SDs below the mean values of ASM, ASM/ht², ASM/BMI, and ASM/wt were 11.96, 4.65, 0.51, and 21.75 in women and 19.26, 6.40, 0.78, and 26.55 in men, respectively. ASM, ASM/BMI, ASM/ht², and ASM/wt were statistically significant positively correlated with handgrip strength (r = 0.81, r = 0.78, r = 0.73, and r = 0.67, respectively; P < 0.001).

Conclusion: In this study, ASM/BMI was found to be the most suitable ASM adjustment method to predict muscle strength.

土耳其成年人参考组中使用双能x射线吸收法测定阑尾骨骼肌质量的截止值。

背景：本研究的目的是确定土耳其人群参考组中通过双能x射线吸收仪（DXA）测量的不同阑尾骨骼肌质量指数（ASMI）方法的临界值。方法：使用DXA进行身体成分分析，并使用身高平方（ASM/ht2）、体重（ASM/wt）和体重指数（BMI）（ASM/BMI）将阑尾骨骼肌质量（ASM）调整为ASMI。性别特异性临界值分别低于ASM/ht2、ASM/wt和ASM/BMI的平均值1和2个标准差（SD）。结果：共有207名（106名女性和101名男性）健康成年人入选。基于1的特定性别截止值低于ASM、ASM/ht2、ASM/BMI和ASM/wt平均值的SD在女性中分别为14.44、5.45、0.61和24.07，在男性中分别为22.63、7.22、0.90和29.04；2. 低于ASM、ASM/ht2、ASM/BMI和ASM/wt平均值的SD在女性中分别为11.96、4.65、0.51和21.75，在男性中分别为19.26、6.40、0.78和26.55。ASM、ASM/BMI、ASM/ht2和ASM/wt与握力呈正相关（r = 0.81，r = 0.78，r = 0.73和r = 0.67；P 结论：本研究发现ASM/BMI是预测肌肉力量最合适的ASM调整方法。
