Quantification of Bone Mineral contents using dual photon absorptiometry in a normal japanese population-Total body Bone Mineral
Journal of Bone and Mineral Metabolism, 1991Co-Authors: Satoshi Hagiwara, Takami Miki, Yoshiki Nishizawa, Hironobu Ochi, Hirotoshi MoriiAbstract:We established reference values for total body Bone Mineral of normal Japanese subjects utilizing dual photon absorptiometry. The index of measurement, total body Bone Mineral content (TBBM) divided by lean body mass (LBM), might be suitable for the evaluation of total body Bone Mineral. TBBM/LBM did not correlate with age in male subjects; however, reduced Bone Mineral was noted in female subjects after fifth decade. The rate of change in Bone after the fifth decade was 0.82% per year. The Bone Mineral density (BMD) of each region including total body also showed a significant decrease with aging in women after the age of 40. Again no significant age-related changes were obtained in male BMD of any region (head, trunk, pelvis, legs, arms). The annual loss in women after the Bone loss began was 0.72% in total body BMD. The rate of BMD change in each region of Bone after 40 years of age ranged from 0.91% (trunk) to 0.51% (arms) per year. The Bone Mineral content (BMC) in “trunk” portion of TBBM decreased significantly with aging, while BMC of other portions did not show a significant age-related change. These results differ slightly from results which we have already reported for lumbar spine BMD, in which case average annual rates of Bone loss once begun, were 0.32% for male and 0.97% for female.

Bone Mineral content and density in healthy subjects and in osteogenesis imperfecta.
Archives of disease in childhood, 1994Co-Authors: M. W. J. Davie, M. J. HaddawayAbstract:Lumbar spine Bone Mineral density in a cross sectional study of healthy subjects increased by 0.012 and 0.016 g/cm2/year in boys and girls respectively between 5 and 11 years of age. These rates increased five-fold in girls and threefold in boys between the ages of 11 and 13 years as a result of the Bone Mineral content increasing more rapidly than the coronal area at this age. By the age of 11 years the girls had 66% of the coronal area, 61% of the Bone Mineral density, and 41% of the Bone Mineral content of subjects aged 18-23 years. The ratio (lumbar spine Bone Mineral content/body weight) was constant in boys aged 6-13 years, but there were significant variations in girls. Femoral neck Bone Mineral density in both sexes changed little between 6 and 11 years and at 11 years was 69% of the adult values. Subjects with osteogenesis imperfecta had a low Bone Mineral density and Bone Mineral content for their age and weight. The z score of Bone Mineral density at the femoral neck was significantly lower than at the lumbar spine. In patients with recurrent fractures a low Bone Mineral density may help in identifying those with osteogenesis imperfecta and assist in their subsequent management.
