Abstract
Accurate body composition assessment, which includes fat mass (adipose tissue mass, FM), fat-free mass (FFM), and percent fat mass (%FM) is needed to evaluate health and treatment efficacy. The current study compared body composition estimates obtained from the Norland Elite® DXA, BodPod®, and iDXA® before and after a12-week exercise intervention in adults (n=30, BMI 25–35 kg/m2). Bland-Altman methods determined mean bias and limits of agreement for FM, %FM, and FFM between methods. Compared to the iDXA® and BodPod®, Elite® overestimated BF% and FM (P <.01). FFM was similar between iDXA® and Elite® but lower in Elite® than BodPod® (P <.01). There were no differences between methods in changes in FM or FFM after the exercise intervention. Prior to this study, it was unknown how the Norland Elite®, a DXA model marketed to bariatric surgery patients, compared to other common body composition assessment methodologies.
