目的:从生物力学角度探讨骨质疏松症的危险因素,对骨质疏松症的骨密度诊断和骨强度诊断作一初步比较。

方法:分析股骨上端骨密度(BMD)、体重(BW)、全身脂肪含量(TBF)、下肢肌肉分布系数(MDC)、下肢最大肌力(MS)、股骨颈抗骨折能力等因素之间的相关性;以T值大小为依据,对骨密度诊断法和骨强度诊断法作简单比较。

结果:①股骨上端骨密度的生物力学影响因素从大到小依次是:下肢最大肌力、体重、下肢肌肉分布系数、全身脂肪含量;②658%的受试者骨密度诊断与骨强度诊断结果基本一致,体重指数(BMI)越大的受试者,越容易趋向一致。

结论:体成分中主要是肌肉对骨密度起决定作用,肌力对骨密度的影响比肌肉成分更重要。

Correlation between BMD and it’s biomechanical factors and the investigation for MS,FS in Shanghai women

Abstract:

Objective:To explore risk factors of osteoporosis from biomechanics point of view and to make a simple comparison between BMD and bone strength diagnosis.

Methods:The correlation factor was analyzed such as BMD,BW,TBF,MDC,MS etc.comparison between BMD and bone strength diagnosis according to the T-score of the FS and BMD.

Results:From maximum to minimum,the effect to BMD was MS,BW,MDC,TBF.The results of BMD diagnosis and bone strength diagnosis were consistent approximately in majority(65.8%).The more magnus the BMI was,the more consistent the results were.

Conclusion:Muscle has a significant positive correlation with BMD in the body content.MS’ effects to BMD is more significant than that of the muscle content.

KEYWORDS:Osteoporosis Bone density Bone strength Diagnosis
