7～15岁城市男、女学生骨龄及形态发育的纵向观察

The longitudinal observation of the skeletal age and morphological growth of the 7～15 urban boy and girl

目的 :探讨少儿骨龄与形态指标的生长发育规律 ,为少儿体质研究提供纵向基础资料。方法 :采用纵向追踪的方法。1985～1993年对测试样本进行了长达9年的追踪观察 ,每年拍摄右手腕部骨龄片 ,并测量身高、坐高、体重、胸围、肩宽、盆宽等6项形态指标。结果 :少儿骨龄与形态指标均值逐年提高 ,女生发育早男生2年左右 ,不同发育类型的发育水平 ,皆为早熟型>平行熟行>晚熟型。结论 :少儿骨与形态发育水平逐年提高 ,具有明显的性别差异 ,不同发育类型的骨与形态发育 ,具有明显的型间差异。

Objective:To investigate the law of growth of skeletal age and morphological parameter and provide the longitudinal fundamental data for children's constitution research.Methods:The longitudinal observation from 1985 to 1993.Every year,take the photograph of skeletal age of right hand ,and measure 6-morphological parameter which include stature,sitting height,body weight ,chest circumference,shoulder breadth,pelvis breadth.Results:The mean of skeletal age and 6-morphological parameter increase year after year,the girl grows earlier two years or so than the boy ,and the growth level of various growth categories is precocious>parallel>serotinous. Conclusion :The growth level of skeleton and morphological parameter increase year after year and is obviously provided with sexual difference,and there is apparent difference between various growth categories.
