Popis: Healthy premenopausal and postmenopausal Japanese women were evaluated by longitudinal and cross-sectional studies to assess changes in radial bone mineral density. A total of 300 healthy Japanese women were enrolled in the cross-sectional study, and 126 of them were chosen for the longitudinal study. In the cross-sectional study significantly lower bone mineral density was found in the women over 50 years old. In the longitudinal study, premenopausal women aged 45-54 years showed rate of change of -0.61%/year at the distal radius and 0.49%/year at the radial shaft. The perimenopausal changes were -1.95 and -0.93%/year and the postmenopausal changes were -1.88 and -1.37%/year at the distal radius and at the radial shaft, respectively, in the women aged 45-54 years. These rates of premenopausal and postmenopausal change were similar to those reported for whites in the United States. The strength of the relationship between the rate of change in radial bone mineral density and the anthropometric values, biochemical data, and menopausal status was evaluated by multiple linear regression analysis. Menopausal status had the greatest influence on the rate of change in radial bone mineral density. It is concluded that menopausal status was the most important variable related to bone loss in our longitudinal study and the rate of bone loss was greatest during the early postmenopausal period in healthy Japanese women.
