| 摘 要： | 目的横断面社区研究分析绝经后妇女OSTA指数及多部位定量骨超声（quantitative ultasound,QUS）超声速率（speed of sound,SOS）],探讨该两个指标预测非椎骨骨折的价值。方法采用以色列Sunlisht Omnisense7000P型QUS仪测量513例女性受试者非优势侧桡骨远端1／3、中指近节指骨及胫骨中段SOS。测量受检者身高、体重,计算OSTA指数,上门问卷形式询问骨折史。结果（1）271例绝经后妇女桡骨、指骨、胫骨SOS显著低于242例绝经前妇女,P〈0．001。（2）绝经后妇女非椎骨骨折组桡骨SOS低于无骨折组（P=0．044）,发生于绝经后的非椎骨骨折妇女,指骨SOS低于无骨折组（P=0．003）。（3）以OSTA〈-4、-4- -1、〉-1将绝经后妇女分为骨质疏松高、中、低风险3组。随骨质疏松风险增加,发生于绝经后的非椎骨骨折率明显升高（χ^2=6．370,P=0．041）,且桡骨、指骨、胫骨SOS显著下降。（4）OSTA取-1及指骨SOSt值取-1．95反映绝经后非椎骨骨折的敏感性分别为75％和81％,特异性分别为48％和40％,受试者工作特征曲线下面积（AUC）分别为0．64和0．66。两者结合敏感性为83％,特异性提高至84％,AUC为0．64。结论OSTA和QUS尤其是指骨SOS具有反映绝经后妇女非椎骨骨折的能力。这两种非常简单、廉价、无创伤性的检查方法有助于筛查高危骨折风险的绝经后妇女。

| Abstract: | OBJECTIVE: To assess a simple and non-invasive scoring system, osteoporosis self-assessment tool for Asians (OSTA) and quantitative ultrasound (QUS) measurement to identify Chinese postmenopausal women with non-vertebral fracture. METHODS: Data came from 513 healthy women. Speed of sound (SOS) of the radius, phalanx and tibia was assessed using the instrument of Omniscience (Sunlight Ltd. Israel). Body height and weight were measured. Body mass index and OSTA were calculated. Self-reported fractures were identified using a structured questionnaire. RESULTS: SOS of radius was significantly lower in women with non-vertebral fracture than those without. SOS of phalanx was significantly lower in women with a history of postmenopausal non-vertebral fracture than those without. Using cut-offs of OSTA -4 and -1 to categorize osteoporosis risk, SOS of radius, phalanx and tibia decreased with increasing risk, while the prevalence of non-vertebral fracture increased.
