Short term in vivo precision of whole body composition measurements on the Horizon® A densitometer

The use of dual-energy X-Ray absorptiometry (DXA) has progressively increased in the assessment of irregularities in body composition commonly correlated with disorders such as obesity, sarcopenia, diabetes, anorexia, human immunodeficiency virus, lipodystrophy, malabsorption and neuromuscular disorders. Athletes also use body composition measurements because increases in lean mass lead to increases in strength, power, agility and overall athletic performance. The purpose of this research was to ascertain the short-term in vivo accuracy and least significant change in serial body composition dynamics provided by the Hologic Horizon A densitometer as currently no published, peer-reviewed body composition accuracy data exists on Horizon scanners in medical literature.
