(1) Background: This study evaluated the clinical implications of a new measurement technique for muscle mass using discrete multi-wavelength near-infrared spectroscopy (DMW-NIRS) compared with multifrequency bioelectrical impedance analysis (BIA) in older adults. (2) Methods: In a cross-sectional study involving 91 participants aged 65 years, the agreement of total lean mass for each measurement was assessed using the intraclass correlation coefficient (ICC) and Pearson’s correlation analysis. The study was conducted at a university hospital from 10 July 2023 to 1 November 2023. (3) Results: A total of 45 men (mean age, 74.1) and 46 women (mean age, 73.6) were analyzed. In the comparisons of total lean mass between DMW-NIRS and BIA, ICC (2.1) was 0.943 and Cronbach’s α coefficient was 0.949 (p < 0.001). Across all segments of lean mass, we found excellent agreement with the ICCs (>0.90) and acceptable values of the correlation coefficients (>0.6) between DMW-NIRS and BIA. (4) Conclusions: This study confirmed agreement in the measurements of muscle mass between portable devices using DMW-NIRS and BIA among community-dwelling older adults. A simple screening of muscle mass in a home setting would help to detect early decreases in muscle mass.

离散多波长近红外光谱与生物电阻抗分析在社区老年人肌肉质量评估中的比较

(1) 背景:本研究评估了使用离散多波长近红外光谱 (DMW-NIRS) 与多频生物电阻抗分析 (BIA) 的新型肌肉质量测量技术在老年人中的临床意义。 (2) 方法:在一项涉及 91 名 65 岁参与者的横断面研究中,使用组内相关系数 (ICC) 和 Pearson 相关分析来评估每次测量的总瘦体重的一致性。该研究于2023年7月10日至2023年11月1日在一所大学医院进行。 (3)结果:总共分析了45名男性(平均年龄,74.1岁)和46名女性(平均年龄,73.6岁)。在 DMW-NIRS 和 BIA 之间的总瘦体重比较中,ICC (2.1) 为 0.943,Cronbach's α 系数为 0.949 (p < 0.001)。在瘦体重的所有部分中,我们发现 DMW-NIRS 和 BIA 之间与 ICC 高度一致 (>0.90),并且相关系数值可接受 (>0.6)。 (4) 结论:本研究证实了使用 DMW-NIRS 和 BIA 的便携式设备在社区老年人中测量肌肉质量的一致性。在家庭环境中对肌肉质量进行简单的筛查将有助于检测肌肉质量的早期下降。
