| 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。 |

| 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. |
