摘要
运用曲线拟合统计方法,建立曲线拟合模型,对1995-2005年浙江城市汉族学生断面的BMI指数曲线拟合后比较分析。结果表明,1995-2005年浙江省城市汉族7~22岁男女生BMI指数均值总体随着年龄递增而增长,男女生BMI指数快速增长主要集中在8~12岁和8~11岁年龄段,城市女生BMI指数突增期较男生提前1~2岁。
After comparative analysis of Han students' section of the BMI index in Zhejiang City from 1995 to 2005,we established curve fitting model based on using curve fitting statistical methods.The results show that,7~22 years old Han students BMI mean index increased with age in Zhejiang province city from 1995 to 2005,both boys and girls;the boys rapid growth age mainly concentrated on 8~12 years,and girls on 8~11 years;girls BMI index growth spurt is 1~2 years old more than boys.
