生长减速期少年体型与骨发育的对比观察

The Comparative Observation of Somativ Types and Skeletal Mature on Growth Decelerated Period

采用克托莱指数判定青春发育期生长减速阶段少年的体型（纤细、适中、粗壮）共观察１５～１７岁男生和１４～１６岁女性２１０人。检测身高、体重、肩宽、骨盆宽，拍摄手腕骨Ｘ光片，判定骨龄，并测量Ⅱ掌骨皮质厚度，计算骨皮质指数。结果表明：男女各年龄组粗壮型少年的骨龄均值明显高于适中型（Ｐ＜００５）；反映骨矿化程度的Ⅱ掌骨皮质厚度和皮质指数不同体型间差别不明显。各年龄组肩宽和骨盆宽均值粗壮型大于适中型，除１７岁男生外，各性别年龄组不同体型的骨盆宽差异显著（Ｐ＜００５），提示用骨盆宽代表横育水平对此年龄段更有意义。

According to their Quetlet Indices,the students′ somatic types(sturdy,moderate,slender)were evaluated in adolescent growth decelerated period.A total number is 210,including 15～17 year old males and 14～16 years old females.The height,weight ,shoulder breadth,and pelvic breadth were measured.The skeletal age and skeletal cortex index were calculated.The results showed that ,in both sexes,the mean values of skeletal age were significantly higher in sturdy group than those in moderate group(P<0 05).But the variety of metacarpal Ⅱ cortex thickness and cortex index which representing skeleta calcification was not significant among different somatic type groups.The mean values of shoulder breadth and pelvic breadth in sturdy group were wider than those in moderate gorup in each age groups.In both sexes and each age groups,the pelvic breadth variety was significant(P<0 05),except in 17 year old group.These suggested that pelvic breadth can represent the width development and it is more important to certain age group.
