Table 4 Logistic regression analysis of central obesity defined by WC for sarcopenia parameters according to sex

Characteristic^a	Unadjusted model		Fully adjusted model
Characteristic^a	Male OR (95% CI)	Female OR (95% CI)	Male OR (95% CI)	Female OR (95% CI)
Muscle strength Low HGS	1.187 (0.578-2.437)	0.704 (0.393-1.260)	1.130 (0.506-2.526)	0.748 (0.400-1.399)
Muscle mass Low ASMI	0.463** (0.303-0.708)	0.326** (0.208-0.508)	0.446** (0.281-0.709)	0.307** (0.189-0.500)
Physical performance Low SPPB	1.295 (0.651-2.574)	1.256 (0.766-2.059)	1.434 (0.691-2.975)	1.252 (0.173 -2.128)
Sarcopenia^b	0.517 (0.229-1.168)	0.264** (0.115-0.605)	0.490 (0.194 -1.240)	0.262** (0.106-0.649)

The fully adjusted model was adjusted for age, hypertension, dyslipidemia, osteoarthritis, osteoporosis, diabetes mellitus, smoking history, alcohol history, location of residence, family group, number of medications, and the MMSE-KC score
Central obesity defined by waist circumference ≥ 90 cm for men and ≥ 85 cm for women
WC waist circumference, OR odds ratio, CI confidence interval, HGS hand grip strength, ASMI appendicular skeletal muscle mass index, SPPB short physical performance battery
^aLow HGS, < 28 kg for males and < 18 kg for females; low ASMI, < 7.0 kg/m2 for males and < 5.4 kg/m2 for females; low SPPB, score ≤ 9 for both sexes
^bSarcopenia: low ASMI (< 7.0 kg/m2 for men and < 5.4 kg/m2 for women) and either low HGS (< 28 kg for men and < 18 kg for women) or low physical performance (SPPB score ≤ 9 for both sexes)
