重庆市儿童青春期生长突增的骨龄研究

A study on bone age in relation to adolescent growth spurt of the children in Chongqing

目的 :探讨骨龄与青春期生长突增之间的关系 ,为重庆市儿童青春期生长突增的判断提供骨龄量化指标。方法 :对重庆市 5 0 0名 7～ 16岁健康儿童进行CHN法骨龄评估 ,其中发育正常者以Grave法确定其所处生长突增阶段 ,统计每一阶段的骨龄值范围 ,并求中位数。结果 :男童骨龄从 11.7岁、女童骨龄从 9.5岁进入加速期 ;男童骨龄 14 .2岁、女童骨龄 12 .3岁进入高峰期 ;男童骨龄 15 .9岁、女童骨龄 14 .8岁进入减速期。结论 :CHN法骨龄评估为判断青春期生长突增提供了量化指标 ,对正畸及用药时机的选择具有重要的指导意义。

Objective:To explore the relationship between the bone age and adolescent growth spurt(AGS),in order to establish a quantitative standard for determination of AGS of the children in Chongqing.Methods:Five hundred healthy children in Chongqing,aged from 7 to 16 years,were enrolled in this study.The bone ages were measured with CHN method in all children.Three phases of adolescent growth spurt were determined by Grave method in normal developing group.The range and median of the bone ages in every phase were analysed statistically by gender.Results:In Chongqing children,the accelerative phase of AGS started at 11.7 years for boys,and 9.5 for girls.The peak phase started at 14.2 years and 12.3 years for boys and girls respectively.The decelerative phase of AGS started at 15.9 years for boys and 14.8 years for girls.Conclusion:The assessment of bone ages provides a quantitative standard for determination of AGS,which is of help for orthopedists to determine the time of operation.
