目的 观察儿童生长发育的规律，了解近１０ 年来青岛市区儿童生长发育趋势。 方法 在１９８６年１ 月～１９９５ 年１２ 月间出生、经过系统管理、资料完整的万名０ ～３ 岁儿童中，随机抽取８５０ 名分成三个组，分别为１９８６ ～１９８９ 年组、１９９０ ～１９９２ 年组、１９９３ ～１９９５ 年组，比较各不同年龄组体重和身长的平均值及标准差。 结果 各组不同年龄体重与身长的均值高于国内１９８５ 年的儿童生长发育参照值；２ 倍和３ 倍出生体重分别于生后第３ 月和第１１ ～１２ 月，生后第１２ 月时身长为出生时的１ ．５ 倍；体重和身长基本的趋势是１９９３ ～１９９５ 年＞ １９９０ ～１９９２ 年＞ １９８６ ～１９８９ 年，统计学处理后体重在小年龄组（４２ 天～６ 月） 有显著性差异，而身长则在大年龄组（２４ ～３６ 月） 有显著性差异。 结论 青岛地区儿童体格发育的指标呈逐渐上升的势态，而且此种生长发育长期加速的趋势是从婴儿时期开始的。青岛市儿童的体格发育在３ 岁前能够达到发达国家的水平。
Objective To observe the law of children’s growth and development and to understand the growth and development trend of children in Qingdao in the recent 10 years. Methods From January 1986 to December 1995, a total of 850 young children aged 0 ~ 3 years, who were systematically managed and completed in data collection, were randomly divided into three groups: the group from 1986 to 1989, and the group from 1990 to 1992 Year group, from 1993 to 1995, comparing the mean and standard deviation of body weight and length of different age groups. Results The average body weight and body length of different age groups were higher than the reference value of children’s growth and development in 1985 in China. The 2-and 3-birth-weight body weights were significantly higher on the 3rd and 11th to 12th days after birth and on the 12th day after birth 1 for birth The body weight and body length tended to increase from 1993 to 1995. From 1990 to 1992, from 1986 to 1989, there was a significant difference in body weight between the young age group (42 days to June) Large age group (24 ~ 36 months) have significant differences. Conclusion The physical fitness of children in Qingdao showed a gradual upward trend, and the long-term acceleration of growth and development started from infancy. Qingdao physical development of children before the age of 3 to reach the level of developed countries.
