AI Article Synopsis
- The study aimed to compare body fat percentage (BF%) estimates from upper body (UB) and lower body (LB) bioelectrical impedance analysis (BIA) devices to those from whole body (WB) BIA.
- Ninety-four participants were evaluated using LB, UB, and WB BIA devices, along with air displacement plethysmography (ADP) for accuracy.
- Results showed that both UB and LB BIA devices significantly underestimated BF% compared to WB BIA and ADP for both men and women.
Article Abstract
Objective: The purpose of this study was to determine if upper body (UB) and lower body (LB) bioelectrical impedance analysis (BIA) devices yield similar estimates of BF% as whole body (WB) BIA.
Approach: Ninety-four men and women had their body composition evaluated using a Baseline 12-1190 Body Fat Scale (Fabrication Enterprises Inc.) as the LB BIA device, an Omron HBF-306C Handheld Body Fat Loss Monitor (Omron Healthcare, Inc.) as the UB BIA device, and a Seca Medical Body Composition Analyzer 514 (Seca North America) as the WB BIA device as well as via air displacement plethysmography (ADP; BodPod; Life Measurement Inc.).
Main Results: in women, the BF% was greater for WB BIA compared to UB BIA and LB BIA (28.9 ± 5.0 versus 23.8 ± 4.4 versus 20.4 ± 5.9%; p < 0.001) with no differences between the WB BIA and ADP BF% (28.9 ± 5.0 versus 28.3 ± 7.5%; p = 0.982). In men, BF% was greater for WB BIA compared to UB BIA and LB BIA (19.1 ± 6.7 versus 15.5 ± 5.3 versus 14.9 ± 4.0; p < 0.001) with no differences between the WB BIA and ADP BF% (19.1 ± 6.7 versus 17.6 ± 7.8; p = 0.394).
Significance: Our findings suggest that the UB and LB BIA devices used in this study underestimate BF% compared to a WB BIA device and ADP in men and women.

This study investigated the intra-day and inter-day reliability of electrical impedance myography (EIM) components and explored sex and regional differences in healthy adults' anterior thigh muscles. Using a multifrequency device, impedance values across various frequencies, alongside 50-kHz resistance (R), reactance (Xc), and phase angle (PhA) were assessed in both sexes and at whole anterior thigh, proximal and distal regions. Findings revealed excellent reliability (ICC > 0.

Objective: Metabolic syndrome (MetS) and sarcopenia together pose significant health risks, increasing frailty, falls, and fractures in older adults. This study compared muscle mass measurements obtained using two different dual-energy X-ray absorptiometry (DXA) machines and bioelectrical impedance analysis (BIA), and evaluated the accuracy of these measurements in these older adults.
Methods: In this prospective multicenter cohort study, patients aged ≥ 65 years with MetS had their muscle mass assessed using both BIA and DXA.

Background: Ureteral stents are one of the most used devices in Urology, allowing drainage of the upper urinary system, and can be used either in elective or emergency procedures. However, as a foreign body inside the urinary system, they are subject to encrustation. Encrustation is one of the burdens seen with double-J stents and, to date, there is no consensus about its best management.

Multifrequency BIA (MF-BIA) may improve accuracy and precision using octopolar contacts for segmental analyses.
Purpose: Evaluate reliability, biological variability, and accuracy of component measures (total body water, mass, and composition) of commercially available MF-BIA system (InBody 770, Cerritos, California, USA).
