Dual-Energy X-Ray Absorptiometry in Body Composition

Body weight and height were measured to calculate BMI using the Quetelet index (kg/m²). Body composition was determined in all subjects by the dual-energy X-ray absorptiometry (Lunar DXA, GE-Healthcare Madison, WI, USA) scanning. Participants were required to wear light clothes, remove all metal objects from their body, and lie supine with arms at their sides while they were completing the scan. The scanner allows the simultaneous measurement of total body fat, trunk fat and android fat mass independent of bone mass. CoreScan software was used to estimate the visceral fat mass based on measurement of abdominal area and subcutaneous adipose tissue (15 (link), 24 (link), 25 (link)).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
