绝经后妇女由于卵巢功能减退,骨失去了雌激素的保护作用,致使骨转换率明显增高,骨吸收增多,骨丢失加速,年丢失量约占全部骨量的2.5~5%,此过程持续5~10年,尤以绝经后的前三年丢失速度最快[1],所以,妇女绝经后骨质疏松症(Poshmenopausalosteoporsis,PMOP)的发病率高于同龄男性。
Postmenopausal women due to ovarian dysfunction, bone loss of estrogen protective effect, resulting in significantly increased bone turnover, increased bone resorption, accelerated bone loss, the annual loss of about all the bone mass 2.5 to 5%, the process lasted 5 ~ 10 years, especially in the first three years after menopause. [1] Therefore, the incidence of postmenopausal osteoporosis (PMOP) is higher in women than men of the same age.
