Application of Quantitative Ultrasound in Determination Bone Mineral Density Situation of Children and Adolescents

Abstract:

Objectives: Use quantitative ultrasound technology to determine the bone density of children and adolescents, understand the status and variation of ultrasonic bone density in children and adolescents.Methods: By stratified random cluster sampling, selected 3629 studenes in five schools in Tangshan and measured height and weight,and determined the right foot heel bone density using ultrasonic bone density analyzer.Results: It showed that the average of ultrasonic bone mineral density were 1535.4±20.6(m/s), decreased at the age of 6 to 9 years old and then increased with the age growth; at the age of 9 was the lowest, the SOS value of ultrasonic bone mineral density rebounded slightly from 10 to 13-year-old, after 13-year-old the SOS value increased with the age growth, the highest was at the age of 19. Ultrasonic bone density was associated with height,weight and body mass index.Conclusions: The development of the bone is a dynamic continuous evolutionary process, bone mineral density presented different rules for the different of age, gender, physical development status.
