跟骨强度指数与影响因素相关性分析

目的：探讨跟骨强度指数与其影响因素的相关性。方法：共入选1024例体检人员。（1）通过Achilles定量超声（QUS）系统测量左跟骨强度指数;（2）使用RGC-120型体重秤测量身高、体重并计算体重指数;（3）通过问卷调查收集体检人员年龄、膳食、运动、吸烟、饮酒等影响因素的相关资料;（4）将各影响因素与跟骨强度指数进行相关分析和多元逐步回归分析。结果：（1）直线相关分析结果显示,跟骨强度指数与身高、体重、体重指数、饮用牛奶年数、运动年数呈正相关（;2）多因素逐步回归分析显示,跟骨强度指数仅与体重指数、运动年数具有显著的回归效果。结论：体重指数与运动年数是跟骨强度指数的独立影响因素,对骨质疏松的诊断与预防具有重要的意义。

Correlation of Calcaneus Stiffness Index and Its Influencing Factors

Objective：To study the correlation between calcaneus stiffness index and the influencing factors.Methods：We selected 1024 people in checkup.（1）We measured stiffness index of left calcaneus by Achilles quantitative ultrasound（QUS） systems;（2）We used the RGC-120 body weight scale to survey height,the body weight and calculates the body weight index;（3）We collect medical personnels＇ age,diet,exercise,smoking,drinking and other information of relevant factors by questionnaire surveies;（4）And associated all the factors with calcaneus stiffness index to carry on straight line correlation analysis and multiple regression analysis.Results：（1） The straight line correlation analysis result showed that the calcaneum stiffness index was positive correlated with height,body weight,body weight index,years of drinking milk,years of movement;（2） The results of multiple regression analysis showed that calcaneus stiffness index only has a significant regression effect with body weight index and years of movement.Conclusion：Body weight index and years of movement are the independent factors of calcaneus stiffness index.They are significant on the diagnosis and prevention of osteoporosis.
