目的了解广西汉、壮、瑶族7～18岁学生形态发育的动态变化,为开展有针对性的干预工作提供参考依据。方法对广西7～18岁壮、汉、瑶族学生1985年以来的6次体质健康调研资料进行分析。结果 2010年广西汉、壮、瑶族学生身高、体重与1985年相比均有明显增长,但胸围增长不明显,壮族男生、瑶族男生、瑶族女生呈负增长;各指标的增幅有民族差异,汉族学生各指标的平均增幅远高于壮、瑶族,壮、瑶族之间差异不大;历年来各民族学生身高增幅最大年龄未出现明显提前,身高的成年性差变化不明显。汉、壮族男、女成年身高、体重均随时间的推移而增长,胸围波动较大;瑶族各指标均有波动。结论广西学生形态发育仍具有长期加速的潜能。应对生长发育的民族差异性进行深入研究,促进各民族学生生长发育水平的均衡发展。
Objective To understand the dynamic changes of morphological development of Han, Zhuang and Yao ethnic groups in Shaanxi Province from 7 to 18 years old, and to provide reference for carrying out targeted intervention work. Methods The data of 6 physical health investigations conducted by Guangxi Zhuang, Han and Yao students from 1985 to 1985 were analyzed. Results The height and weight of Han, Zhuang and Yao students in Guangxi increased significantly compared with those in 1985, but the growth of bust was not obvious. The number of Zhuang boys, Yao boys and Yao girls increased negatively. The growth of each index varied from ethnic group to Han ethnic group The average increase of each index is much higher than that of Zhuang, Yao, Zhuang and Yao ethnic groups. The maximum height growth of ethnic minority students did not appear obvious advancement over the years, and the difference of height adult was not obvious. Han, Zhuang male and female adult height and weight increased with time, chest circumference fluctuations; Yao indicators are volatile. Conclusion Guangxi students still have the potential for long-term accelerated morphological development. We should conduct an in-depth study of the national differences in growth and development and promote the balanced development of the growth and development of all ethnic groups.
