So the developmental condition of children''s bone and related risk factors of bone quality are our major concern in this research.　　The first purpose of this resarch is to establish the bone quality data measured by ultrasonic equipment at the ag from 7 to 11 among Taichung County''s girls. The second purose is to find important risk factors. In the research, the sample size focuses on 2085 girls. All girls in the sample received calcaneal ultrasonic measuring. The results can be showed by different age level: 7 years old-44.60±9.98, 8 years old-48.04±10.96, 9 years old-52.60±10.86, 10 years old-56.13±11.11, 11 years old 60.23±11.40 (Unit: BUA dB/MHz*cm).　　Among 22 related risk factors, there are only 4 risk factors to reveal significant influence: BMI (Body Mass Index), Allergic rhinitis, Asthmatic drugs, Menstruation.　　We also analyze the correlation between sample girls and their parents. The result are diferent for fathers (r=0.04, P<0.6) and mother (r=0.155, P<0.007).　　Substantially, we conclude that the volumn of calcium intake and the activity of girls do not appear to be important risk factors, nor genetic factor. All of above give us the implication to perform long-term logitudinal studies in order to get more information.骨質密度女童thesis
