一、问题提出当前,我国用来评价中小学生生长发育参照的“骨龄标准”,是1990年国家体委采用哈尔滨、西安、福州等发达城市的中小学生为样本研制的“CHN标准”,实践证明,用来评价我国广大农村中小学生的生长发育水平误差较大。特别是在我国中小学生生长发育普遍提前、加速的趋势下,再用十年前的“标准”来评价当今中小学生的生长发育水平那就更缺乏准确性;因不同地域之间的群体或个体,由于受生活条件、环境因素等方面的影响,中小学生发育水平也存在着较大差异．如:城市与农村、南方与北方均存在差异,所以制定符合本地区的“中小学生骨发育成熟度评价标准”就具有必要性、可行性和准确性。
First, the problem raised At present, the “bone age standards” used to evaluate the growth and development of primary and secondary students in our country are the “CHN standards” developed by the State Sports Commission in 1990 with primary and secondary students in developed cities such as Harbin, Xi’an and Fuzhou. Practice shows that, Used to evaluate the vast majority of rural primary and secondary students in China’s growth and development level of error. Especially in primary and secondary schools in our country growth generally in advance, accelerating trend, and then use the “standard” ten years ago to evaluate the level of growth and development of today’s primary and secondary school students that lack of accuracy even more; due to different regions of the group or individual Due to the influence of living conditions and environmental factors, there is also a big difference in the level of development of primary and middle school students. Such as: urban and rural areas, southern and northern differences exist, so to develop in the region “primary and secondary school students bone development maturity evaluation criteria” is necessary, feasible and accurate.
