Associations between Physical Fitness, Bone Mass, and Structure in Older People

Table 3

Partial correlation coefficients between bone mass variables and physical fitness in females, for age, tibia length, and muscle area as possible confounders.

Trochanter aBMD (g/cm^2)	0.253	0.019	0.152	-0.150	0.167	0.130
Total hip aBMD (g/cm^2)	0.267	-0.053	0.195	-0.053	-0.111	0.074

LB: lower body; pQCT: peripheral quantitative computed tomography; DXA: dual-energy X-ray absorptiometry; aBMD: areal bone mineral density. Significant correlations are in bold numbers.
