Bone density measurements of 14 individuals (early Bronze Age, 2200-1600 BC), analyzed by dual-energy absorptiometry, showed a distinct difference between women and men. In men, there was a high bone density (+17.9%-0.290 g/cm2 difference). In females, a constant decrease in bone density was found after the age of 20-25 years (from 1.2 g/cm2 at 20 years to 0.8 g/cm2 at 40 years of age). With caution, the results are comparable with those of the present time.
