土家族苗族城镇中小学生体表面积对比分析

目的比较土家族和苗族城镇中小学生体表面积的差异,为建立中小学生生长发育健康指标评价体系标准提供依据。方法采用适合中国人的Stevenson标准公式分别计算土家族和苗族中小学生的体表面积,并进行对比分析。结果土家族和苗族中小学生体表面积均随着年龄增长而增长,其增长速度男女生也均可分为匀速、快速、减缓3个时期,但二者生长发育各个时期的年龄段划分并不完全相同;土家族学生体表面积整体生长发育水平低于苗族学生。结论土家族学生体表面积的生长发育规律与苗族学生不完全一致,且整体生长发育水平低于苗族学生。

A Comparative Analysis of Body Surface Area Between Tujia and Miao Students of Primary and Middle Schools

Objective To find out the differences of body surface area between Tujia and Miao students, and to provide reference for making a health appraisal system for students' growth and development. Methods Stevenson Formula was used to get the body surface areas of Tujia and Miao students respectively.The results of the students of two nationalities were compared. Results The body surface area of both Tujia and Miao students increased with their ages, and the increasing speed can be divided into three stages: normal, quick, and slow. The body surface area development of Tujia students was lower than Miao students. Conclusion In terms of body surface area development, the regular patterns of Tujia and Miao students are not exactly the same, the former is lower than the latter.
