预防医学在老龄化社会中很重要。肌肉减少症前期是肌肉减少症的初期阶段。生物电阻抗分析（BIA）设备的最新进展使得能够自动估计颈围（NC）。然而，手动测量的NC与BIA计算的NC之间的一致性和可重复性尚未得到评价。我们在健康检查的背景下进行了这些分析，并调查了它们与前驱减少症的关系。 我们招募了318名参与者，他们接受了人体测量，包括手动和BIA测量的NC;身体功能评估;和血液测试。我们使用Bland-Altman分析来计算BIA和手动方法的NC测量之间的一致性和可重复性。然后，我们对正常受试者和前驱减少症患者进行了统计学比较。使用多变量分析，我们随后调查了显着的危险因素前减少症。我们根据四肢骨骼肌指数（aSMI;手臂和腿部骨骼肌质量与身高的比值2）定义了消瘦前症。 Bland-Altman分析显示，偏倚（BIA-manual）总体为负（-1.07），男性参与者为负（-1.23），女性参与者为负（-0.96）。这一发现表明，与手动测量相比，BIA测量被低估了。通过BIA进行的NC测量与手动方法可以互换，因为男性参与者（3.81%）和女性参与者（4.58%）的总体误差百分比小于5%（4.38%）。单变量分析显示，NC是显着较小的参与者与presparkeness比那些没有。调整混杂因素后的多变量分析显示，NC降低与前驱减少症显著相关。 NC的BIA测量与手动测量在约95%内可互换。在两种性别中，通过BIA测量的NC的降低与前驱减少症显著相关。NC测量可用于早期发现前驱减少症。
Preventive medicine is important in an aging society. Presarcopenia is the preliminary stage of sarcopenia. Recent advances in bioelectrical impedance analysis (BIA) devices have enabled automatic estimation of neck circumference (NC). However, the agreement between and interchangeability of NC measured manually and that calculated with BIA have not been evaluated. We performed these analyses in the context of health checkups and investigated their associations with presarcopenia. We enrolled 318 participants who underwent anthropometric measurements, including NC measured manually and by BIA; assessment of physical function; and blood testing. We used Bland-Altman analysis to calculate the agreement between and interchangeability of NC measurements by BIA and by the manual method. We then statistically compared normal participants and those with presarcopenia. Using multivariable analysis, we subsequently investigated significant risk factors for presarcopenia. We defined presarcopenia according to the appendicular skeletal muscle index (aSMI; the ratio of arm and leg skeletal muscle mass to height2). Bland-Altman analysis showed that bias (BIA-manual) was negative overall (−1.07), for male participants (−1.23), and for female participants (−0.96). This finding suggests that BIA measurement is an underestimate in comparison with manual measurement. NC measurement by BIA was found to be interchangeable with that by manual methods, inasmuch as the percentage error was less than 5% overall (4.38%), for male participants (3.81%), and for female participants (4.58%). Univariable analysis revealed that NC was significantly smaller in the participants with presarcopenia than in those without. Multivariable analysis, adjusted for confounding factors, revealed that a decrease in NC was significantly correlated with presarcopenia. BIA measurements of NC are interchangeable within about 95% with manual measurements. The decrease in NC measured by BIA was significantly associated with presarcopenia in both genders. NC measurement can be used for early detection of presarcopenia.
