学龄前儿童生长发育调查分析

为了解和评价学龄前儿童生长发育状况，从湖州市随机抽取11所幼儿园共1426名3～7岁儿童进行调查，研究结果表明：学龄前儿童身高每增长1cm，男、女儿童的体质量分别增长0.304kg、0.380kg；身高增长与体重增长呈非线性关系；BMI、Quetele指数、身高胸围指数与年龄均呈线性关系，并且该三个指数高于我国北方某些农村调查结果，由此可见，湖州市学龄前儿童身高与体重的增长比例严重失调，体质量过大。

A Survey and Analysis of Preschool Children Growth

To find out and evaluate the situation of preschool children's growth and maturity, the authors randomly investigated 1426 preschool children (within 11 kindergartes in Huzhou) and found that as preschool children grow 1 cm taller, the weight of male children and female children increases 0.304kg and 0.380kg respectively. It is not the height increase and weight increase but BMI, Quetelet index, height-breast index and age that show a linear relation. These three indexes are higher than those of the children in some rural areas in north China according to one investigation, from which the authors conclude that the height and weight of the preschool children in Huzhou are out of balance as they have excessive weight.
