| 目的 评估亚洲骨质疏松自我评估工具(OSTA)和体重指数(BMI)预测社区绝经后妇女骨质疏松症的效果。方法 利用双能X线吸收仪测定320例绝经期女性的骨密度，计算OSTA指数和体重指数，并评价他们对于骨质疏松症的预测效果。结果 腰椎和股骨颈骨质疏松检出率分别为25. 9%和35. 9%，OSTA指数和BMI都和骨密度有明显的相关性。以OSTA≤- 1作为临界点，预测腰椎、股骨颈骨质疏松症的灵敏度和特异度分别为75. 3%和69. 1%。如果按照BMI >23. 0相应的指标为 67.0%和55.6%。结论 OSTA指数和BMI对于绝经后妇女骨质疏松症都有一定的预测价值，但是灵敏度都特别低。相比而言，OSTA指数更为简单方便，也有更好的评价效果。 |

| Objective To evaluate the application of osteoporosis self-assessment tool for Asians (OSTA) and body mass index (BMI) in screening of osteoporosis for postmenopausal women in communities. Methods A total of 320 postmenopausal women were included. Bone mineral density (BMD) was measured using dual energy X-ray absorptiometry (DXA). OSTA index and BMI were calculated，and their predictive values of osteoporosis for postmenopausal women were assessed，respectively. Results The detection rates of osteoporosis in the lumbar spine and the proximal femur were 25.9% and 35.9% respectively. Both the OSTA index and BMI were significantly correlated with BMD. Using OSTA≤ - 1 as the cut-off value，the sensitivity and specificity of OSTA in the screening of osteoporosis in the lumbar spine and the femur were 75. 3% and 69. 1%，respectively. Using BMI > 23.0，they were 67.0% and 55.6%，respectively. Conclusion Both OSTA index and BMI have certain predictive value in screening osteoporosis in postmenopausal women. However，the sensitivity is low. OSTA index is more convenient and simpler in use. |
