Extracellular Water to Total Body Water proportion (otherwise known as “Edema Index”) measured via BIA is widely accepted and used for both prognosis and evaluation purposes. 

#1: Edema is a predictive factor for mortality

Summary: Monitoring Body Water balance using BIA can help predict all-cause death in hemodialysis patients. Subjects who underwent fluid control (tracked using BIA) had lower risk of all-cause death compared to those in the control group.

Why this is useful: Checking if Edema Index is normal or too high helps evaluate the effectiveness of fluid control. This is crucially important for patients with illnesses that affect body water.

#2 Edema is a reflection of locomotive syndrome risk and frailty

Summary: Extracellular Water (ECW) and Total Body Water (TBW) ratio (Edema Index) was significantly higher among patients with locomotive syndrome risk and frailty.

Why this is useful: This paper helps to expand the utility of Edema Index beyond well-known usages such as evaluation of fluid retention in dialysis. If Edema Index is higher than the standard cut-off point of 0.39, practitioners should consider the higher possibility of locomotive syndrome risk and frailty.

#3 Using the Edema Index to guide disease management provides better survival results

Summary: Identifying patients at risk of heart failure as early as possible is an important challenge. This study tested whether integrating Edema Index-guided patient management (measured using BIA) for 6 months could improve health outcomes for heart failure patients.

Using Edema Index to guide treatment, patients enjoyed better health outcomes compared to the control group. Patients whose Edema Index was controlled to lower than the cut-off point of 0.39 before discharge had fewer adverse health events compared to those with Edema Index above 0.39.

Why this is useful: When Edema Index is used in medical settings to guide and determine suitable treatment, outcomes are improved. Therefore, Edema Index is an important result to monitor and incorporate into medical assessment.

Assessment of muscle mass and strength for diagnosis of sarcopenia is increasingly needed in societies with rapidly growing elderly populations.

#1 Higher Phase Angle is indicative of better strength and aerobic fitness

Summary: This is a systemic review of 34 studies exploring Phase Angle’s relationship with (1) muscle strength, and (2) aerobic fitness.

Higher Phase Angle was associated with higher muscle strength and better aerobic fitness in a vast majority of the studies (only 2 of 34 did not find a direct relationship). This was the case for various age groups and health conditions!

Why this is useful: Charder’s professional body composition analyzers utilize muscle mass, age, phase angle, and other variables to estimate grip strength. This paper helps demonstrate that higher phase angle does indeed correlate with higher strength, explaining why Charder is able to provide such results with improved accuracy.

#2 BIA-assessed sarcopenia has prognostic value

Summary: Sarcopenia is prognostic for numerous health outcome, but it is rarely assessed in routine clinical practice because it is traditionally difficult and time-consuming to diagnose and track. BIA is more portable, easy-to-use, and convenient compared to imaging “gold standard” alternatives, but can BIA-based muscle measurements detect sarcopenia reliably?

In a systemic review of 24 studies regarding the use of BIA in detection of sarcopenia in adults with cancer, researchers concluded that BIA has prognostic value for evaluating low muscle mass and diagnosing sarcopenia. Importantly, two of the studies showed that BIA was comparable to gold standards (CT, MRI), indicating that it is a feasible replacement method.

Why this is useful: BIA is a fast, safe, and convenient method for muscle measurement. However, there are sometimes concerns about accuracy, and whether or not results are reliable enough to be used for diagnosis in medical settings. This systematic review of multiple studies helps prove that in real-world settings, BIA can indeed be used for such purposes.

#3 Elderly adults lose strength faster than they lose muscle

Summary: It is common for people to lose muscle and strength as they age. A 3-year study was conducted to determine how much muscle and strength was lost.

Decline in strength after 3 years was much more rapid than decline in muscle mass. As such, although measurement of muscle is important, assessment of strength is also needed for early detection of sarcopenia.

Why this is useful: Charder’s unique “Muscle Quality” result provides an estimate of grip strength. Why is this necessary, when all other BIA devices only provide muscle quantity? This paper helps explain that because muscle strength declines more rapidly than muscle mass, relying solely on mass can result in sarcopenia being overlooked. Therefore, an estimate of muscle strength may be quite valuable for advance warning signs of potential sarcopenia.

#4 European consensus on best methods for identifying sarcopenia

Summary: A standardized measurement protocol is used to screen and diagnose sarcopenia using various methods.

．Low muscle strength is defined as grip strength < 27 kg for men and < 16 kg for women using dynamometer
．Low muscle mass is defined as Appendicular Skeletal Muscle Index (ASMI) <7.0 kg/m2 for men and <5.5 kg/m2 for women using BIA

Why this is useful: This paper outlines the common European standards for grip strength and muscle mass using BIA – patient’s results can be compared to these cut-off points to help evaluate sarcopenia.
