作者使用国产SPA-Ⅰ型骨矿分析仪测量了成都地区7～16岁汉族中、小学生498名(其中男生255名,女生243名)的桡骨骨矿含量,提出了成都地区汉族少年、儿童桡骨的g/cm骨矿含量正常值。发现不论是男生或女生的g/cm骨矿含量值均与年龄、身高和体重有十分密切的线性正相关关系,其相关系数男生分别为0.83、0.77、0.64;女生分别为0.82、0.82、0.82,而且其g/cm骨矿含量的年增长高峰均在13岁。 The authors used domestic SPA-Ⅰ bone mineral analyzer to measure the radial bone mineral content of 498 middle school and primary school students (including 255 boys and 243 girls) in Chengdu aged 7-16 years old. G / cm bone mineral content normal. Found that boys and girls regardless of g / cm bone mineral content values ​​and age, height and weight have very close linear correlation, the correlation coefficient boys were 0.83,0.77,0.64; girls were 0.82,0.82,0.82 , And its g / cm bone mineral content of the annual growth peak at 13 years of age.
