- All results are mean score (95% CI) from multivariate linear regression controlling for age, height, FEV1/FVC, race, education, and smoking history.
- Results are from separate multivariate linear regression of each score regressed on body composition measures plus covariates.
- Boldface when p < 0.05 *p = 0.07
- Each Short Physical Performance subscale score ranges from 0–4, with higher scores reflecting more favorable performance. Summary performance score is sum of each subscale score and ranges from 0–12.
- Lean/fat ratio = derived from bioelectrical impedance. Results are expressed per 0.50 increment in the ratio.
- SAD = sagittal abdominal diameter, an estimate of visceral fat. Results are expressed per 1 cm increment.
- BMI = body mass index, an estimate of adiposity; normal weight (18.5 to 24.9 kg/m2) overweight = 25.0 to 29.9 kg/m2, obese = 30.0 kg/m2 or greater; only 9/355 (2.5%) of subjects were in underweight category (< 18.5 kg/m2) so these were included in the normal weight group
