我们在1981～1985年5年中对清华大学幼儿园儿童共测量10次身长及体重。测量对象为3～6岁健康儿童,每半年测量1次,10次总计为6280人次,其中男童3389人次,女童2891人次。测量结果与北京市1975年学龄前期儿童生长发育标准相比较。我园儿童身长在标准均值以上者平均占45%,体重在标准均值以上者平均占69%,女童较男童的百分比略高,各年龄组大致相似。为了观察5年中我园儿童身长和体重的变化,将首次(1981年初)及末次(1985年末)的测量结果作为重点,进行了以下的对比。(1)均值的变动:将3～6岁的男女童,以半岁
We measured total body weight and weight of children from kindergartens in Tsinghua University during the five years from 1981 to 1985. Measuring objects for 3 to 6-year-old healthy children, measured once every six months, 10 times a total of 6280 passengers, of which 3389 were boys and 2891 were girls. Measurement results and Beijing 1975 pre-school children growth and development standards compared. Children in our park average 45% above the standard mean and those who weigh above the standard mean averages 69%. The percentage of girls in girls is slightly higher than that of boys and are similar in all age groups. In order to observe the changes in the height and weight of children in our park during the five-year period, the following comparisons were made focusing on the measurements of the first (beginning of 1981) and the last (1985) measurements.
