中国儿童身高体重Z评分现状分析（1992）

An analysis on the anthropometrical measurements of preschool children of China──Z score and % of children with Z score >2(1992)

利用国家统计局１９９２年对全国２９个省、市自治区近１８万名五岁以下儿童的体格测量数据，分析了各省、市、自治区儿童的身高／年龄、体重／年龄和体重／身高的Ｚ评分值及其分布。结果表明：我国儿童身高和体重都比世界卫生组织的标准低，而身高更差些，农村儿童比城市儿童差。另外我国儿童Ｚ评分值＞２的人数百分数并不多，城市和农村也差别不大，各省间城市和农村身高Ｚ评分＞２的人数百分数的中位数为２．９２％和２．３２％，体重则分别为２．３５％和２．１５％，而按身高的体重的中位数分别为３．３６％和９．４７％。农村儿童按身高的体重Ｚ评分＞２的儿童比例多，主要是由于其身高差的程度比体重大所致，故不宜单独以此指标来评价儿童生长发育。

Described are the findings of the anthropometrical data of nearly 180000 under 5 children of 29 provinces, autonomus regions and municipalities collected by the State Statistic Bureau in 1992. The provincial average Z scores of height for age and weight for age were lower than the WHO reference standard. Height was worse than weight and children in rural areas was worse than in urban. The proportion of children with Z score > 2 was similar to the reference. There were no much difference between urban and rural. The fact that the higher proportion of rural children with weight for height Z score >2 is due to the larger deficit of their height than weight.
