Bone mass and density of the head
(1995) In European journal of experimental musculoskeletal research 4(2). p.51-55- Abstract
Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry in the upper half of the skull, in 324 residents (178 women and 146 men, age-range 20-87 years) in the city of Malmo, Sweden. Since muscular activity influences the skeleton we found it was of interest to compare one region influenced by physical load with one virtually unaffected by physical stress. The skull may be assumed to be the region least affected by physical load and therefore least influenced by physical activity. By choosing the upper half of the skull as region of interest we minimized the influence of the muscles of the neck, and excluded the influence of dental artefacts. For comparison, the BMD of the femoral neck, representing bone under... (More)
Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry in the upper half of the skull, in 324 residents (178 women and 146 men, age-range 20-87 years) in the city of Malmo, Sweden. Since muscular activity influences the skeleton we found it was of interest to compare one region influenced by physical load with one virtually unaffected by physical stress. The skull may be assumed to be the region least affected by physical load and therefore least influenced by physical activity. By choosing the upper half of the skull as region of interest we minimized the influence of the muscles of the neck, and excluded the influence of dental artefacts. For comparison, the BMD of the femoral neck, representing bone under physical load, and the BMD entire skull and total body were measured in the same individuals. Women increased their BMD by 7% in the upper part of their skulls during the first two decades of adult life. Thereafter, BMD decreased with age (27%). Men lost their BMD in the upper part of the skull at the same rate throughout adult life (7%). In the femoral neck in both women (34%) and men (28%) BMD decreased continuously with age. The two regions, the upper part of the skull and the femoral neck, were correlated, in women r = 0.54 (p < 0.0001) and in men r = 0.41 (p < 0.0001). All included, the BMD in the upper part of the skull was found to be 6% higher in women than in men (p = 0.001). In the femoral neck the men had 12% higher BMD than the women (p < 0.0001). The age-related changes in bone mass appear to differ between weight-loaded and unloaded bone. Also, this is to our knowledge the first observation of a higher bone mineral density in women than in men.
