对土家族城镇中小学生体表面积调查研究

Survey on School Students' Body Surface Area in Tujia Nationality Towns

为了解和建立土家族中小学生这方面的形态学指标,采用适合中国人的Stevenson标准公式,对土家族中小学生的体表面积进行了调查研究。结果显示:1)土家族中小学生体表面积值随着年龄增长而增长,且其增长速度男女生均可分为匀速增长期、快速增长期、速度减缓期3个不同时期;2)男女生体表面积曲线出现双交叉现象,即11岁时女生体表面积值超过男生,14岁时男生的体表面积又超过女生,15岁以后二者体表面积值的差异逐渐增大,表现出显著性差异。

In order to find out and determine the morphology index of middle and primary school students' body surface area of Tujia nationality, this paper makes a survey on it with Stevenson Formula, which is suitable for the Chinese. The findings show that 1) their body surface area increases with their age and both male and female students' increasing speed can be divided into three periods, namely, normal, high-speed and slow increase periods. 2) Male and female students' body surface area curves displays a double cross that of female exceeds male's at the age of 11,while that of male's exceeds female's at 14; after the age of 15, the difference gradually increase to a remarkable degree.
