To prepare for the problems associated with a rapidly aging society, a checkup for the bone mineral density has been performed in many cities and villages in Japan.
However, there are varying methods for measuring bone mineral density, and the usefulness of quantitative Ultrasound imaging has not been established.
The relationship between bone mineral density and life style in 627 women in 5 cities was investigated using quantitative ultrasound imaging to measure bone mineral density.
The results can be summarized as follows:
1. The results from quantitative ultrasound imaging can be applied to the established DXA method because there was a correlation among dual energy X-ray absorptiometry, single energy X-ray absorptiometry and quantitative ultrasound imaging.
2. The stiffness index by quantitative ultrasound imaging was highly correlated with age and decreased proportionally with an increase in age.
3. We suggest that the measurement of bone mineral density by quantitative ultrasound imaging for women at the age of 55 and 60 years in addition to those of 40 and 50 years is necessary.
4. We speculate that exercise and calcium intake during youth have some effects on bone mineral density of women after the prime of life.
