沈阳地区青少年上肢长的生长发育特征

Study on growth and development of the length of the upper limbs of students in Shenyang

目的了解沈阳地区青少年上肢长的生长发育规律。方法采用邵象清的人体测量方法,调查了沈阳地区7～17岁的1134名(男551名,女583名)青少年的上肢长,并与上海及大连的资料进行了比较。结果沈阳青少年的上肢长随年龄的增长而增长,上肢长/身高指数男性从15岁,女性从13岁以后呈递减趋势。在7～12岁年龄组,男、女性上肢长/身高指数沈阳地区均小于上海地区,与大连地区比较无显著差异。结论上肢长有明显的性别差和地区差,且生长发育有随年龄增长而增长的规律性。亦可能与体育锻炼有关。
