摘要

背景:测定身体组成成分——肌肉和脂肪量——是临床和流行病学研究的重要步骤。定量测定体成分最常用的方法是间接法。然而,所使用的各种方法和设备模型使得在群体和个人层面上对数据进行直接比较变得困难。目的:本研究的目的是分析在一组男性和女性中使用生物阻抗分析仪ABC-02«Medas»(STC Medas,俄罗斯),770InBody (InBody,韩国)和超声波扫描仪BodyMetrix BX2000 (IntelaMetrix,美国)获得的脂肪和瘦体重绝对值估计值以及身体脂肪质量比例的一致性。材料和方法:进行了一项观察性、单中心、横断面、非对照研究。测量主要的人体测量特征(身高、体重、腰围)。采用生物阻抗法(BIA)测定人体组成,770InBody装置采用八极结构,ABC-02 Medass装置采用四极结构,BodyMetrix BX2000 (BM)超声扫描仪进行超声扫描。计算绝对体脂量(FM)、相对体脂量(PBF)和瘦体重。结果:共检查48例,其中女性38例,男性10例,年龄24 ~ 74岁。研究对象的人体测量特征呈现在一个广泛的范围内。各对体组成成分之间均存在较强的相关性:PBF - ABC-BM对最小值为0.853 [0.730,0.913],FM - ABC-InBody对最大值为0.988[0.977,0.993]。此外,除BIA法测定的PBF外,所有测量对均发现显著的统计学差异(p<0.001)。BIA估计的绝对脂肪量显示出高一致性(CCC>0.95),中等一致性(CCC>0.95)是不同BIA分析仪确定的PBF的特征,对于所有其他对测量的一致性可以评估为弱(CCC> 0.90)。结论:两种不同的BIA分析仪(InBody和ABC)对FM的估计在群体和个人水平上是最一致的。

[Interchangeability of different indirect methods for determining body composition].

Background: Determination of body composition components - muscle and fat mass - is an important step in clinical and epidemiological studies. The most common methods for quantitative determination of body composition are indirect methods. However, the variety of methods and models of devices used makes direct comparison of data at both group and individual levels difficult.

Aim: The aim of the study is to analyze the consistency of estimates of absolute values of fat and lean body mass, as well as the proportion of body fat mass, obtained using bioimpedance analyzers ABC-02 «Medas» (STC Medas, Russia), 770InBody (InBody, Korea) and ultrasound scanner BodyMetrix BX2000 (IntelaMetrix, USA) in a group of men and women.

Materials and methods: An observational, single-center, cross-sectional, uncontrolled study was conducted. The main anthropometric characteristics (height and weight, waist circumference) were measured. Body composition was determined by bioimpedancemetry (BIA) using the octopolar scheme on the 770InBody device and the tetrapolar scheme on the ABC-02 Medass device and ultrasound scanning using the BodyMetrix BX2000 (BM) ultrasound scanner. The absolute (FM) and relative amount of body fat (PBF) and lean body mass were calculated.

Results: A total of 48 people (38 women and 10 men) aged 24 to 74 years were examined. The anthropometric characteristics of the examined subjects were presented in a wide range. A strong correlation was found for all pairs of body composition components: the minimum value for the pair PBF ABC-BM was 0.853 [0.730, 0.913], the maximum was 0.988 [0.977, 0.993] for the pair FM ABC-InBody. Also, significant statistical differences (p<0.001) were found for all pairs of measurements, except for PBF determined by the BIA method. High agreement (CCC>0.95) of BIA estimates of the absolute amount of fat mass was shown, moderate agreement (CCC 0.9-0.95) is characteristic of the PBF determined by different BIA analyzers, and for all other pairs the agreement of measurements can be assessed as weak (CCC<0.90).

Conclusion: The best agreement at the group and individual levels was found for FM estimates by two different BIA analyzers (InBody and ABC).
