Abstract

Objectives

In an era when telemedicine is becoming increasingly essential, the development and validation of miniaturized Bioelectrical Impedance Analysis (BIA) devices for accurate and reliable body composition assessment is crucial. This study investigates the BIA Metadieta, a novel miniaturized BIA device, by comparing its performance with that of standard hospital BIA equipment across a diverse demographic. The aim is to enhance remote health monitoring by integrating compact and efficient technology into routine healthcare practices.

Methods

A cross-sectional observational study was conducted with 154 participants from the Clinical Nutrition Unit. The study compared resistance (R), reactance (Xc), and phase angle (PhA) measurements obtained from the BIA Metadieta device and a traditional hospital-based BIA device.

Results

Analysis revealed strong positive correlations between the BIA Metadieta and the hospital-based device for R (r = 0.988, P < 0.001), Xc (r = 0.946, P < 0.001), and PhA (r = 0.929, P < 0.001), indicating the miniaturized device's high accuracy and reliability. These correlations were consistent across different genders and BMI categories, demonstrating the device's versatility.

Conclusions

The BIA Metadieta device, with its miniaturized form factor, represents a significant step forward in the field of remote health monitoring, providing a reliable, accurate, and accessible means for assessing body composition.

用于远程身体成分监测的便携式生物阻抗分析仪：受控条件下的临床研究

目标在远程医疗日益重要的时代，开发和验证用于准确可靠地评估身体成分的微型生物电阻抗分析（BIA）设备至关重要。本研究通过比较 BIA Metadieta 这种新型小型化 BIA 设备与标准医院 BIA 设备在不同人群中的性能，对其进行了调查。方法对临床营养科的 154 名参与者进行了横断面观察研究。研究比较了 BIA Metadieta 设备和传统医院 BIA 设备获得的电阻 (R)、电抗 (Xc) 和相位角 (PhA) 测量值。结果分析表明，BIA Metadieta 和医院设备在 R (r = 0.988, P < 0.001)、Xc (r = 0.946, P < 0.001) 和 PhA (r = 0.929, P < 0.001) 方面具有很强的正相关性，表明微型设备具有很高的准确性和可靠性。这些相关性在不同性别和体重指数类别中都是一致的，这表明该设备具有多功能性。结论BIA Metadieta 设备采用微型化外形，在远程健康监测领域迈出了重要一步，为评估身体成分提供了可靠、准确和方便的方法。

期刊介绍： Nutrition has an open access mirror journal Nutrition: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Founded by Michael M. Meguid in the early 1980''s, Nutrition presents advances in nutrition research and science, informs its readers on new and advancing technologies and data in clinical nutrition practice, encourages the application of outcomes research and meta-analyses to problems in patient-related nutrition; and seeks to help clarify and set the research, policy and practice agenda for nutrition science to enhance human well-being in the years ahead.
