The purpose of this study is to measure bone mineral density and bone mineral content in middle school female adolescents to examine their relationship with physical composition and suggest estimation in order to get a more rational understanding of properties of adolescents` growth and development and provide basic scientific data necessary for exercise prescription. The study subjects were 194 students aged 13 to 15 of S middle school located in Seoul. Their body composition was estimated with InBody 4.0 and their BMD and BMC were measured with Dual Energy X-ray Absorptiometry(PRODIGY, GE Medical System Lunar). The results were as follows. 1) From the results of correlation analysis among the body constitution, BMD and BMC were positively correlated with all items, of which skeletal muscle mass showed the highest correlation. 2) From the results, the formulas of total BMD and BMC were estimated as follows. Total BMD={0.364×Skeletal muscle mass(kg)}+{0.242×Age(yr)}+{0.291×Body mass index(kg/m²)}(R²=.452) Total BMC={0.734×Skeletal muscle mass(kg)}+{0.149×Age(yr)}+{0.154×Percent body fat(%)}(R²=.707)

This study was performed to examine the correlation among body composition, bone mineral density(BMD) and bone mineral content(BMC) of Korean female students were measured and formulas for estimation were suggested. The study subjects were 350 students of S Women`s University in Seoul. Their body composition was estimated with InBody 4.0 and their BMD and BMC were measured with Dual Energy X-ray Absorptiometry(PRODIGY, GE Medical System Lunar). The results were as follows. 1) From the results of correlation analysis among the body constitution, BMD and BMC were correlated of fat mass, fat-free mass, lean body mass, Body Mass Index, weight showed the highest correlation. 2) From the results, the formulas of total BMD and BMC were estimated as follows. Total BMD=1.380+0.002(Height)-0.004(Weight)+0.011(Lean Body Mass) (R2=.215) Total BMC=584.097+72.557(Lean Body Mass)+18.327(Fat Mass) (R2=.573)
