Abstract

Ethnic factors affect bone mass acquisition during childhood. The aim of our study was to establish normative data for bone mineral content (BMC) and bone mineral density (BMD) in healthy Korean children and adolescents, using 446 lumbar spine scans (224 males and 222 females) and 364 proximal femur scans (181 males and 183 females) of healthy children between ages 2 and 18 years measured by dual-energy X-ray absorptiometry using Hologic QDR Discovery A 2004. There was an increase in both BMC and BMD during early childhood, acceleration during the adolescence spurt, and a slower increase later. Until 11 years of age, both male and female BMC and BMD were not statistically different. There was a rapid increase in both BMC and BMD in females earlier than in males, and later males caught up with the females and overshot the female values. When compared with Canadian children, BMD and BMC of total proximal femur was found to be more and BMD and BMC of total lumbar spine to be less at some ages. Tanner's stage was significantly associated with BMD and BMC of spine and proximal femur in males and BMC of spine in females in the first three Tanner's stages. Height, body weight, fat content, and body mass index influenced BMC and BMD at different sites by variable amount. Hence, the values presented in this study should be used as reference values in Korean children and adolescents.
