摘　　要：目的 探究20世纪90年代末期南京地区的女性儿童发育水平的变化趋势。方法 选择南京地区9-15岁汉族女性儿童400名,采用CHN法的手腕骨发育等级标准评定其骨发育等级,进而得到每个年龄段的骨发育成熟度得分标准,与CHN法骨发育成熟度得分标准相比较。结果 在9-13岁年龄段南京地区的女性儿童骨发育成熟度得分标准高于CHN法标准;在14岁年龄段南京地区的女性儿童骨发育成熟度得分标准低于CHN法标准;在15岁年龄段南京地区的女性儿童骨发育成熟度得分标准与CHN法标准无明显统计学差异。结论 由于地区及时间等因素的变化,20世纪90年代末期南京地区的女性儿童的骨骼发育呈现出提前发育的趋势,因此有必要制定本地区现阶段的各年龄段青少年儿童骨发育水平的标准。Objective To explore the trend of bone maturity of the female children in Nanjing at the end of 90's. Methods 400 Nanjing female children were chosen to assess the bone maturity by the CHN scoring method. The standards of the bone maturity in Nanjing were compared with the one of the CRN's at every age. Results The standard of Nanjing is higher than the CRN's at the age of 9 - 13, but at the age of 14 the standard of Nanjing is lower than the CRN's. There is no statistical difference between the standard of Nanjing and the CRN's at the age of 15. Conclusion At the end of 90's, the tendency of the bone maturity advanced in Nanjing female children because of the changing of the area and time. So it is necessary to establish a new current standard for this area.
