Correlations between muscle mass and conceptually related functional and health-related quality of life variables
| Variable | ASM/ht2 | ASMBMI |
|---|---|---|
| 6MWD | 0.16* | 0.21* |
| Frailty (SPPB) | 0.15* | 0.14* |
| SF12-PCS | 0.11 | 0.13* |
| Trails B Test score | −0.05 | −0.09 |
| SF12-MCS | −0.02 | 0.001 |
Definition of abbreviations: 6MWD = 6-minute walk distance; ASM = appendicular skeletal muscle mass; BMI = body mass index; EWGSOP2 = European Working Group on Sarcopenia in Older People 2; FNIH = Foundation for the National Institutes of Health; SF12-MCS = Short Form 12 Mental Health Composite Score; SF12-PCS = Short Form 12 Physical Health Composite Score; SPPB = Short Physical Performance Battery.
ASM/ht2 was used in lowest quartile and EWGSOP2 definitions. ASMBMI was used in FNIH definitions.
