摘　　要：目的研究7～18岁儿童少年的生长发育趋势.方法采用随机整群分层抽样的方法,于1963、1973、1981、1985、2003年对沂蒙山区7～18岁城、乡儿童少年的身高、体重、胸围、坐高准确测量.结果40年来,城市男、女儿童少年平均每10年的身高分别增加3.81cm和3.16cm,体重分别增加3.30kg和2.32kg;乡村男、女儿童少年平均每10年的身高分别增加3.61cm和3.12cm,体重分别增加2.67kg和2.24kg.儿童少年的生长发育表现出明显的男、女差异和城、乡差异.男、女儿童少年各项形态指标的两次交叉年龄提前2～3年;突增高峰年龄:城市男、女儿童少年提前2～3年,乡村男、女儿童少年提前1～2年.结论四项形态指标发育水平有逐年提高的趋势,为今后政府部门的决策提供了可靠依据.Objective To explore the trend of growth and development of children aged 7-18. Methods Children aged 7-18 in Yimengshan Mountain Area were sampled in 1963, 1973, 1981,1985 and 2003 and their heights, weights, chest circumferences and sitting heights were measured accurately. Results According to the surveys, the average heights of boys and girls in cities have risen by 3.81cm and 3, 16cm respectively and their body weights have risen by 3.30kg and 2.3kg respectively. The average heights of boys and girls in countryside have risen by 3.61cm and 3.12cm respectively, and their body weights have rised by 2.67kg and 2.2kg respectively.
