[Senile osteoporosis in normal women examination using dual energy X-ray absorptiometry].
Osteoporosis is now one of the most serious problems in aged Japanese women. We investigated bone mineral contents of the vertebrae of 132 adult women (28-94y.o.) using dual energy X-ray absorptiometry (DEXA) in order to clarify the change of the bone mineral densities (BMD) with aging, and the influences of a diet and exercise on osteoporosis. In the women, BMD of the vertebrae increase to maximum level in 3 rd or 4 th decade of life, and then reduce with aging. The level of BMD is well matched with the index of osteopenia using the lateral view of vertebral X-ray. According as the BMD reduce, the number of bone fractures and the number of patients with bone fractures increase. More than 80% of the women whose BMD are less than 0.7 g/cm2 have bone fractures. In aged women, over 65 year's old, exercise had significant positive effect with BMD, but that was no evidence for influence of calcium intake to BMD.
