摘要
目的 :了解侗族儿童青少年超声骨密度的变化规律及其影响因素。方法 :采取定量超声技术(QUS)测定广西750名9～15岁侗族儿童青少年的跟骨QUS参数超声振幅衰减系数(BUA),同时测量身高及采用生物电阻抗法测量体成分。结果 :9～15岁侗族儿童青少年BUA值随年龄的增长而增加。男、女13、14岁同年龄组BUA差异有统计学意义。9～15岁男、女生BUA与年龄、体质量、身高、BMI、肌肉量和脂肪量均呈正相关。结论 :年龄和体质量是影响侗族儿童青少年跟骨BUA的重要因素。本研究获得侗族儿童青少年定量超声BUA正常参考值,为侗族儿童少年骨质疏松症诊疗提供依据,为指导和改善侗族儿童青少年钙营养提供依据。
Objective:To understand the change pattern of the calcaneus broadband ultrasound attenuation(BUA)in normal Dong ethnicity aged from 9 to 15 years and its correlation factors.Methods:The calcaneal BUA of 750 Dong ethnicity children and adolescents in Guangxi was measured by using osteospace dry ultrasound bone densitometer.And then,height and body composition were measured.Results:The BUA values of children and adolescents of Dong ethnicity increased with age.There were differences in BUA values of boys and girls of 13 and 14 years old.BUA was positively correlated with age,height,weight,BMI,muscle mass,and fat mass among boys and girls aged between 9 and 15 of Dong ethnicity.Conclusion:This finding provides a normal reference to evaluate the bone strength in children and adolescents of Dong ethnicity,which is correlated with age and weight.Additionally,this reference offers a basis for diagnosing osteoporosis.
