骨質疏鬆症（Osteoporosis）的風險評估重點在於雌激素水平、年齡與遺傳因素。停經後婦女因卵巢功能衰退，體內雌激素急劇下降，導致蝕骨細胞（Osteoclasts）活性增加，骨質流失速度大幅超過造骨細胞（Osteoblasts）的修復能力。高加索裔（Caucasian）女性因骨密度基礎值通常較低，被列為臨床篩檢的最高風險族群。
Postmenopausal Caucasian women are at the highest risk for osteoporosis due to estrogen deficiency, which accelerates bone resorption by increasing osteoclast activity. This rapid bone loss exceeds the repair capacity of osteoblasts, particularly in individuals with lower baseline bone density.
