Low Bioelectrical Impedance Phase Angle Is a Significant Risk Factor for Frailty

Table 2

Comparison of demographics and phase angle by frailty and LS status among the total sample.

	Frailty			LS
Variables	Non-frailty; (N = 498)	Frailty; (N = 52)		Non-LS; (N = 484)	LS; (N = 66)
Age (years)	64.2 (10.0)	67.9 (10.3)	0.015	64.1 (9.8)	67.7 (11.5)	0.003
Sex (male/female)	228/270	7/45	< 0.001	214/270	21/45	0.063
BMI (kg/m^2)	23.7 (3.4)	21.8 (3.6)	< 0.001	23.5 (3.4)	23.9 (4.0)	0.51
Phase angle (°)	5.1 (0.6)	4.5 (0.6)	< 0.001	5.1 (0.6)	4.8 (0.7)	< 0.001

< 0.05, < 0.01, and < 0.001, Mann-Whitney U test, Fisher’s exact test.
Parameter values are shown as means (standard deviations) or numbers. Italic text indicates a significant difference.
BMI: body mass index; LS: locomotive syndrome.
