- Results are from separate multivariate logistic regression of self-reported functional limitation regressed on body composition measures plus covariates.
- Lean/fat ratio = derived from bioelectrical impedance. Odds ratios are expressed per 0.50 increment in the ratio.
- SAD = sagittal abdominal diameter, an estimate of visceral fat. Odds ratios 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.
