OBJECTIVE: To analyze the relationship of the height difference and bone density (BD) of premenopausal and postmenopausal women. METHODS: The height values of 191 premenopausal and postmenopausal women were recorded, and the BD values of lumbar vertebrae and hip were detected by double energy X-ray BD detector. RESULTS: The lower the height of the postmenopausal women, the less the BD value. The BD of lumbar vertebrae dropped 0.025 5 g/cm(2) with each 2 cm of the shortened height, and the BD of hip joint dropped 0.029 2 g/cm(2). The shortened value in postmenopausal women with osteoporosis was statistically greater than that in postmenopausal women without osteoporosis. CONCLUSION: The BD of the postmenopausal women can be estimated by the calculation of their shortened height value.
