Logistic regression analysis of central obesity defined by WC for sarcopenia parameters according to sex
| Characteristica | Unadjusted model | Fully adjusted model | ||
|---|---|---|---|---|
| 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) |
| Sarcopeniab | 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)
