In this study bone status was assessed using a quantitative ultrasound (QUS) technique at the calcaneus in 141 healthy, prepubertal, Turkish schoolchildren (80 girls, 61 boys) aged 6-12 years. Broadband ultrasound attenuation (BUA, DB/MHz) was measured with a prototype pediatric contact bone analyzer (CUBA, McCue Ultrasonics Ltd). The relation of age, body weight and height to BUA was assessed. BUA increased linearly with age in boys and girls (R=0.448, p=0.0001 and R=0.382, p=0.002, respectively). BUA values in boys tended to be higher than in girls, reaching significance only at the age of seven years with a 95% confidence interval. In conclusion, the measurement of BUA in the calcaneus with QUS has important clinical implications in assessing bone mass in children. Further studies in not only healthy children but also in those with metabolic bone diseases would be helpful in order to evaluate its sensitivity and reproducibility.
在本研究中，采用定量超声（QUS）技术对141名6至12岁健康的青春期前土耳其学童（80名女孩，61名男孩）的跟骨骨状况进行了评估。使用原型儿科接触式骨分析仪（CUBA，McCue Ultrasonics Ltd）测量宽带超声衰减（BUA，dB/MHz）。评估了年龄、体重和身高与BUA的关系。男孩和女孩的BUA均随年龄呈线性增加（分别为R=0.448，p=0.0001和R=0.382，p=0.002）。男孩的BUA值往往高于女孩，仅在7岁时达到显著差异，置信区间为95%。总之，用QUS测量跟骨的BUA对评估儿童骨量具有重要的临床意义。不仅对健康儿童，而且对患有代谢性骨病的儿童进行进一步研究，将有助于评估其敏感性和可重复性。
