In the management of bone health, the most important issue is how the period until peak bone mass is spent, that is, appropriate self management for bone health.This study examined for bone growth estimation considering skeletal maturation and how to guidance on bone health in adolescents.In 2000〜2001, the following investigations were carried out ; investigation of physical characteristics such as body height and body weight, body mass index, measurement of cortical bone mineral density of the second metacarpal bone by the digital image processing method (DIP method), evaluation of bone age using X-ray film by the same method, and cancellous bone mass of calcaneal bone was measured by ultrasound using the ALOKA-AOS100, and OSI(osteo sono-assessment index), TI(Transmission index) and SOS(speed of sound) was used as an index of bone mass, dietary survey for 3 days, a health status questionnaire, menstrual status and years since menarche and so on. Therefore, we evaluated factors affecting BMDs (DIP method and Ultrasound method) and skeletal maturation in adolescent girls.In this study, to clarify bone growth estimation-associated factors, the correlation between BMDs and various factors (physique, years after menarche, bone age) was analyzed by single regression analysis. OSI and TI by the ultrasound method showed higher positive correlation with body weight and BMI than with bone age. These data indicated that factors affecting BMD findings by the DIP method and OSI, TI by the ultrasound method differed. These results suggest that bone growth estimation by the ultrasound method is useful in evaluating BMD in adolescent girls, when considering skeletal maturation in relation to appropriate physique, years since menarche.

在骨健康管理中，最重要的问题是如何度过骨峰值，即适当的骨健康自我管理。本研究探讨了考虑骨骼成熟的骨生长估计和如何指导青少年骨健康。2000 - 2001年，进行了以下调查：调查身体特征，如身高和体重，体重指数，通过数字图像处理方法测量第二掌骨的皮质骨密度（DIP法），通过相同方法使用X线片评估骨龄，并通过使用ALOKA-AOS 100和OSI的超声测量跟骨的松质骨质量（骨超声评估指数），TI（传输指数）和SOS（声速）被用作骨质量的指标，3天的饮食调查，健康状况问卷，月经状况、初潮时间等因素，评价影响BMD的因素本研究旨在探讨青春期女性骨发育的相关因素，以及骨密度与各因素的相关性（体质、初潮后年限、骨龄）进行单因素回归分析。超声法测得的OSI、TI与体重、BMI的正相关性高于骨龄。提示DIP法与超声法测量骨密度的影响因素不同。这些结果表明，骨生长估计的超声方法是有用的，在评估骨密度的青春期女孩，当考虑到骨骼成熟的相关适当的体质，年月经初潮。
