To study changes in the rate of bone loss before and after the menopause, 19 normal premenopausal women of the same age were followed with annual measurements of appendicular bone mass for 8 yr. Their serum estrone, estradiol, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, and vitamin D-binding protein levels also were measured annually. The serum estrogen levels declined before the menopause, and the rate of bone loss more than doubled at the time of the menopause. There were no significant… CONTINUE READING
