【摘要】 目的:了解深圳地区0～1 5岁儿童少年超声骨密度状况;建立其超声骨密度正常参考值。方法:选择0～1 5岁深圳出生和/或居住的正常儿童少年为检测对象,用定量超声骨密度仪(QUS)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:0～72个月龄男童与女童之间BMD无差异(P >0.0 5 ) ;6～1 2岁男童与女童之间BMD存在差别(r =0 73.2 ,P <0.0 0 1 ) ,但经体重校正后差异无显著性(P >0 .0 5 ) ,1 3～1 5岁少年BMD与性别有关;0～1 5岁儿童少年BMD值与身高增长快慢有关。结论:胎儿期储备、合理膳食、体重、运动、雌激素对BMD有影响更多还原

【Abstract】 Objective:To find out the BMD saturation and set up normal consultations to the teenagers in Shenzhen.Methods:selecting 0～15 year-old health teenagers who born or live in Shenzhen as objects,using QUS to determine their calcareous BMD,while measuring their height and weigh.Results:The BMD of the boys and the girls 0～72 mouths-old was no difference (P>0.05).The BMD of 6～12 year-old boy and the girl exists difference(r=0.732,P<0 .001),The difference was disappear after the weight was corrected(P>0.05).The calcareous BMD of 13～15 year-old healthy teenagers has interrelation with the sex and the speed of growth.Conclusion:The speed of the growth evidently interrelates with the variation of their BMD.The condition of fetus,sport and nuteition can influence the BMD.更多还原
