国家体委、教育部、卫生部于1978年初至1980年10月对我国16省市城乡7～17岁年龄组的青少年共145508名身高、体重进行了调查。为了精确描述男女青少年身高、体重与年龄的结构关系,我们对该组数据进行了曲线拟合,并获得生长发育的较优曲线方程。现介绍如下。
The State Sports Commission, the Ministry of Education and the Ministry of Health conducted a survey on the height and weight of 145,508 adolescents aged 7-17 in urban and rural areas in 16 provinces and cities in China from the beginning of 1978 to the end of October 1980. In order to accurately describe the height, weight and age structure of the male and female adolescents, we performed a curve fitting of the data and obtained the optimal curve equation of growth and development. Now introduced as follows.
