体重指数联合腰椎和股骨平均骨密度测量推算全身骨质含量的研究

摘要

目的 分析体重及体重指数与腰椎、股骨平均骨密度和骨矿含量之间的相关关系、比较腰椎、股骨骨密度和骨矿含量值的差异,探讨腰椎、股骨平均骨密度和体重与骨矿含量之间的关系.方法 选取2009年1月到2011年1月来我院进行治疗的166被确诊为骨量减少、骨质疏松症患者,比较L2、L3、L4骨密度及骨矿含量之间的差值,分析L2、L3、L4的平均骨密度和骨矿含量与体重及体重指数之间的相关性关系.结果 3组骨矿含量值与骨密度值两两比较差异显著(P<0.05).腰椎、股骨平均BMC与体重之间呈现出明显的正相关关系(P<0.01),而BMD与体重之间无明显的相关性(P>0.05).结论 三组骨矿含量与骨密度之间存在明显的差异,其中腰椎、股骨平均骨密度和骨矿含量与体重及体重指数之间存在着明显的相关关系,体重在一定程度上会增加骨量,因此保持适当的体重对预防骨质疏松症的发生有重要的临床意义和价值.%To analyze the relationship among weight, hod) mass index, lumbar i erlebra bonernmineral densil) ( HMD), femoral HMD, and bone mineral content, and to cpinpare the difference betweenrnlumber verlebra and femoral HMD and bone mineral content. Methods One hundred and sixly - six osleopenia and osteoporosis patients from January 2009 to January 2011 were chosen as subjects. The difference between L2 -J4 HMD and bone mineral content were compared. The relationship among L2-L4 HMD, bone mineral content, weight, and Bill were analyed. Results The difference between BMD and bone mineral content of the 3 groups were significant (P<0. 05 ). Lumbar verlebra BMC and femoral BMD were positively associated with weight ( P < 0.01 ). lloiveier, BMD was not associated with weight ( P > 0. 05 ). Conclusion The difference between bone mineral content and BMD of the 3 groups are significant. Lumber verlebra BMD and femoral BMD and BMC are associated with weight and BM1. Bone mass increases along with weight. Keeping proper weight is significant for the prevention of osteoporosis.
