Definition of Dual Energy X-ray absorptiometry (DEXA)

A highly accurate method of measuring body composition and bone mass and density using multiple low-energy X-rays

Definition of Air Displacement

A method for estimating body composition that makes use of the volume of space taken up by a body inside a small chamber.

Definition of underwater weighing

A method of estimating total body fat by weighting the individual on a standard scale and then weighting him or her again submerged in water. The difference between the two weights is used to estimate total body volume.

What is upper-body obesity also known as?
