Child Development and Ecology of Minority Races in China

1994年、1995年和1996年，日本-中国合作考察队先后从日本派往中国的实地考察，我们对大陆中国儿童的生长发育进行了实地调查，收集了少数民族和城乡地区的大量数据如下。生长状况(身高、体重、胸围、坐高、肩峰宽、双侧肩宽)，2.营养状况(皮脂)，3.运动能力(跑步、投掷、跳跃)，4.体能(肺活量、肌肉力量、血压)，5.气候和生态指标。我们在联合国和日本的科学期刊上发表了5篇文章。根据这些结果，1.中国儿童的体型在过去40年中总体上呈长期增长的趋势。2.云南少数民族儿童的体型差异较大，其体型与温度、降水、海拔和经度等生态条件有关，由于生活环境相对封闭、近亲繁殖习惯等原因，少数民族儿童的生长发育状况明显低于汉族儿童。

In 1994,1995 and 1996, the Japan-China cooperative study team have sent from Japan to the field site of China, We have conducted a field-survey on the development and growth of children who live in mainland China, and collected a lot of data by minority ethnic groups and urban rural area as following items.1. growth status (height, weight, chest circumference, sitting height, biacromal breadth, bicristal breadth), 2. nutritional status (skinfold fat), 3. motor performance (running, throwing, jumping), 4. physical fitness (vital capacity, muscle strength, blood pressure), 5. climate and ecological indexes. We have contributed five articles to scientific journals of United Nation and Japan.According to these results, 1. An overall increasing secular trend during past four decade is apparent for body size of chinese children. 2. Wide variations of body size could be seen not only chinese children, but also minority ethnic groups in Yunnan province, and their body size correlated with ecological condition of temperature, precipitation, as well as altitude and longitude.Because of the relative closed living environment and the inbreeding habit, the growth and developmental status of minority ethnic children were significantly inferior to those of the Han groups.
