Units: Age (years), height (cm), weight (kg), and aBMD (g/cm²).

SD = Standard deviation.

^aDifferences in the number of data points for each measure within each subgroup are due to missing data.

^bSignificantly different from the older subgroup in the Aging Study.

^cSignificantly different between the middle-age and older subgroups in the Aging Study.
