Differences in body composition assessments measured by air displacement plethysmography and magnetic resonance imaging in adult females

Abstract

J-GLOBAL ID : 202201012804701108J-GLOBAL ID : 202101004237845144Magnetic resonance imaging （MRI） and air displacement plethysmography （ADP） are widely used methods for reliable body composition analysis （BCA）. This study aimed to compare the BCA assessments obtained between MRI and ADP methods in 14 adult females. BCA measurements such as whole-body mass, volume, density, fat mass and %fat mass were analyzed by both MRI and ADP methods. 　The masses, volumes and body densities obtained MRI and ADP method were both absolutely and relatively equaled. However, the %fat masses obtained MRI and ADP method were highly correlated （r＝0.950, p＜0.001）, while significant absolute differences in %fat mass were found between the two methods （p＜0.001）. 　It was suggested that the MRI method equivalently evaluated in mass, volume and body density compared with ADP method. Also, MRI method can be relatively evaluated the fat mass and %fat mass but it overestimated absolute values.1520860078898552704application/pdfdepartmental bulletin pape
