Bivariate correlation matrix among age and body composition variables.
| Age | TBW | ICW | ECW | LTM | BMC | |
|---|---|---|---|---|---|---|
| TBW | -.25 | 1.0 | ||||
| ICW | -.44* | .96** | 1.0 | |||
| ECW | .14 | .85** | .66** | 1.0 | ||
| LTM | -.11 | .88** | .74** | .93** | 1.0 | |
| BMC | -.08 | .62** | .60** | .52** | .63** | 1.0 |
| FM | .04 | .38* | .22 | .56** | .57** | -.04 |
TBW = Total body water; ICW = Intracellular water; ECW = Extracellular water; LTM = Lean tissue mass; BMC = Bone mineral content; FM = Fat mass; Body water estimated from multi-frequency bioelectrical impedance analysis; Body lean, bone, and fat estimated from dual-energy X-ray absorptiometry.
