【摘要】 目的　了解深圳地区儿童超声骨密度状况 ,建立深圳市儿童超声骨密度正常参考值。方法　选择 6～ 12岁深圳居住的正常儿童 6 97例为检测对象 ,用定量超声骨密度仪测定受检者足跟部骨密度 (BMD)值 ,同时测量受检者体重、身高。结果　 6～ 12岁儿童BMD正常参考值 (g/cm2 )分别为 6岁 :0 4 4 5± 0 16 6、7岁 :0 5 0 9±0 15 1、8岁 :0 5 10± 0 133、9岁 :0 5 19± 0 132、10岁 :0 5 2 0± 0 15 3、11岁 :0 5 30± 0 175、12岁 :0 5 4 5± 0 2 0 6。男童与女童之间BMD存在差别但经体重较正后无显著性差别 (P >0 0 5 )。男童与女童BMD随年龄增加呈线性增长 (男 r=0 72 2 ,P <0 0 0 1;女 r=0 785 ,P <0 0 0 1) ,并与体重显著相关 (r=0 984 ,P <0 0 0 1)。结论　 6～ 12岁儿童足跟部BMD与性别无关 ,而与年龄增加呈线性增长 ,这种增长与体重显著相关。更多还原

【Abstract】 Objective To find out the BMD situation and set up normal consultation to the children in Shenzhen.Methods Selecting 6～12-year-old healthy children who live in Shenzhen as objects,using QUS to determine their calcaneus BMD,while measuring their height and weigh them.Results The different normal consultations of 6～12-year-old healthy children’s BMD was 0.445±0.166、0.509±0.151、0.510±0.133、0.519±0.132、0.520±0.153、0.530±0.175、0.545±0.206.The BMD of the boys and the girls was different(r0.732,P<0.001),but the difference disappeared after the weight was corrected.The BMD of the children increased with the age and weight(The boys:r0.722,P<0.001;The girls:r0.785,P<0.001;r0.948,P<0.001).Conclusion The calcaneus BMD of 6～12-year-old healthy children has nothing to dowith the sex,but shows linear increase with the age,which evidently interrelates with weight.更多还原
