Bioelectrical Impedance and Dual-Energy X-Ray Absorptiometry Assessments of Changes in Body Composition Following Exercise in Patients with Type 2 Diabetes Mellitus

Table 2

Subject body composition by method at baseline and change from baseline for overall cohort (men = 23, women = 21, overall = 44).

Method	Variable	Before intervention			Change from baseline for overall cohort
		Men	Women	Overall
DXA	FFM (kg)	64.4 ± 10.2	47.3 ± 8.8^#	56.2 ± 12.8	0.1 ± 1.5
	% FM (%)	27.1 ± 6.3	38.2 ± 4.1^#	32.4 ± 7.7	−1.1 ± 1.4^†
	FM (kg)	25.3 ± 11.4	29.7 ± 8.0	27.4 ± 10.1	−1.3 ± 2.1^†
LBIA	FFM (kg)	64.7 ± 10.5	45.9 ± 6.5^#	55.8 ± 12.9	−0.5 ± 2.2
	% FM (%)	28.5 ± 7.6	40.0 ± 5.9^#	34.0 ± 8.9*	−0.9 ± 2.7^†
	FM (kg)	27.7 ± 13.5*	31.9 ± 11.0*	29.7 ± 12.4*	−1.5 ± 4.2^†

Values are means ± standard deviation. DXA: dual X-ray absorptiometry; LBIA: leg-to-leg bioelectrical impedance analysis; FFM: fat free mass; %FM: percentage body fat; FM: fat mass.
^*Significantly different from DXA (𝑃<0.05).
^#Significantly different from Men (𝑃<0.05).
^†Significant change compared with before intervention (𝑃<0.05).
