摘要:

文题释义:
WHO骨折风险评估系统:是评估患者髋部骨折风险和骨质疏松性骨折风险的简易工具,除了股骨颈骨密度、年龄、性别、既往骨折史和使用类固醇外,该骨折风险评估系统还考虑了其他临床危险因素,以计算髋部骨折或其他主要部位骨质疏松性骨折(脊柱、前臂、上肢手臂)。
双能X射线骨密度仪:可用于测定骨矿物质密度、肌肉量以及脂肪量。目前双能X射线骨密度仪的骨密度测量是临床最常见的检测方法,主要测量中轴骨骨密度包括腰椎和髋部,参照WHO推荐的诊断标准来诊断骨质疏松症。

背景:骨质疏松性骨折患者骨折风险增高独立于骨密度,而肌肉与脂肪对骨折风险的影响尚缺乏量化的评估。
目的:探讨绝经后女性人群中骨密度、肌肉与骨折风险性的关系。
方法:选择在内蒙古医科大学第二附属医院就诊的绝经后女性1 032例,年龄40-90岁,收集其临床资料。采用双能X射线骨密度仪进行身体成分和骨密度测定,通过WHO未来10年骨折风险评估系统问卷进一步分析骨折风险性。
结果与结论:①调查对象平均年龄为64岁(40-90岁),腰椎骨密度、股骨颈骨密度、全髋骨密度、四肢骨骼肌量、四肢骨骼肌指数的平均值分别为(0.78±0.16) g/cm2、(0.64±0.14) g/cm2、(0.76±0.15) g/cm2、(15.9±2.4) kg和(6.57±1.77) kg/m2;②使用骨折风险评估系统计算的10年主要部位骨折风险和髋部骨折风险分别为4.2%(2.8%,6.9%)和1%(0.3%,2.4%);③四肢骨骼肌指数与主要部位骨质疏松性骨折风险和髋部骨折风险呈负相关(P < 0.05);④结果表明,四肢骨骼肌指数与髋部骨折或主要部位骨折风险可能有关。

Abstract: BACKGROUND: The increased risk of osteoporotic fracture is independent of bone mineral density, whereas the effects of muscle and fat on the fracture risk have not been quantitatively assessed.
OBJECTIVE: To identify the relationship between bone mineral density, muscle and the risk of osteoporotic fracture in postmenopausal women. 
METHODS: Clinical data from 1 032 postmenopausal women, aged 40-49 years, who were admitted at the Second Affiliated Hospital of Inner Mongolia Medical University, were collected and analyzed. The bone mineral density and body composition were measured by dual-energy x-ray absorptiometry, and the fracture risks at the major sites in the next 10 years were assessed using the Fracture Risk Assessment Tool (FRAX®), released by the World Health Organization.
RESULTS AND CONCLUSION: The mean age of all the subjects was 64 years (range, 40 to 90 years). Mean bone mineral densities of the lumbar spine, femoral neck, and total hip were (0.78±0.16), (0.64±0.14), and (0.76±0.15) g/cm2, respectively. The appendicular lean mass and appendicular lean mass index were (15.9±2.4) kg and (6.57±1.77) kg/m2 respectively. The fracture risk calculated in 10 years by using the FRAX for hip fracture and major fracture was 4.2% (2.8%, 6.9%) and 1% (0.3%, 2.4%), respectively. The appendicular lean mass index showed a negative association with major fracture and hip fracture risks (P < 0.05). All these findings indicate that the appendicular lean mass index associated with an increased risk of a major fracture or hip fracture.
