This table only shows the results of regressions performed with DXA per cent fat variables because they had the highest adjusted R 2 and lowest SEE values when compared with DXA fat mass variables.
DXA measures of adiposity: DXA APF, dual‐energy X‐ray absorptiometry android per cent fat; DXA TBPF, dual‐energy X‐ray absorptiometry total body per cent fat; DXA VPF, dual‐energy X‐ray absorptiometry visceral per cent fat. DXA android fat variables were measured using automatic ROI for android region.
MRI VFM sum = sum of four slices (L1–L2 + L2–L3 + L3–L4 + L4–L5).
DXA variable was significant (p ≤ 0.05) in regression model; however, anthropometric variable and/or age was not significant.
DXA and anthropometric variables were significant (p ≤ 0.05) in regression model.
Anthropometric variable was significant; however, DXA and/or age were not significant.
BMI, body mass index; DXA, dual‐energy X‐ray absorptiometry; MRI, magnetic resonance imaging; ROI, region of interest; VFM, visceral fat mass; WC, waist circumference.
