NATIONAL OSTEOPOROSIS RISK ASSESSMENT

国家骨质疏松症风险评估（诺拉）是一项公共卫生 该倡议将创建一个纵向的，观测数据库， 50万绝经后的妇女。 从这些收集的数据 患者将提供进行纵向研究的机会， 检查骨质疏松症的危险因素之间的关系，包括 低骨密度和患者结局，如BMD变化 和骨折风险。 初始目标是确定 在多个骨骼部位中的每一个处的BMD测量值与 患者骨折的长期和短期风险。 本分析将试图 将每个测量的增量预测值确定为 以及确定BMD测量的组合，当考虑 结合其他风险因素信息，提供更有预测性和 评估患者骨折总体风险的成本效益方法。

The National Osteoporosis Risk Assessment (NORA) is a public health initiative that will create a longitudinal, observational data base of as many as 500,000 post-menopausal women. The data collected from these patients will offer opportunities to conduct longitudinal research to examine the relationship between risk factors for osteoporosis including low bone mineral density and patient outcomes such as changes in BMD and fracture risk. The initial objective is to determine the relationship between BMD measurements at each of a number of skeletal sites and a patient's long and short term risk of fracture. This analysis will attempt to determine the incremental predictive value of each of the measurements as well as identify combinations of BMD measures that, when considered in conjunction with other risk factor information, offer a more predictive and cost-effective method of evaluating a patient's overall risk of fracture.
