    摘要:

    目的:建立江苏省7~17岁儿童青少年体重指数(body mass index,BMI)百分位数参考值和曲线,为评价生长发育特点提供科学依据。方法:基于“2021年江苏省学生常见病和健康影响因素监测”项目,采用分层随机整群抽样法在江苏省13个市26个县(市、区),共选取45 595名7~17岁中小学生进行体格检查,使用偏度系数-中位数-变异系数法(LMS法)建立江苏省儿童青少年BMI百分位数参考值,拟合出相应的百分位数曲线并与全国水平比较。结果:江苏省7~17岁男女生BMI均随年龄增长而增加。男童9岁时BMI进入增长高峰,12 岁后增长减缓,女童10岁时BMI进入增长高峰,14 岁后增长减缓。江苏省儿童青少年各年龄组BMI 5 th、50 th、95 th百分位数均高于全国水平。结论:本研究呈现了江苏省儿童青少年的BMI分布状况; 基于LMS 法获得了江苏省儿童青少年BMI 百分位参考值和生长曲线,拟合效果良好;江苏省各年龄组男女生BMI主要百分位数均高于全国水平,各年龄组男生BMI中位数均大于女生。

    Abstract:

    Objective:This study aims to establish percentile reference values and curves of body mass index(BMI)for children and adolescents aged 7 to 17 in Jiangsu Province,providing a scientific basis for evaluation of growth and development characteristics. Methods:Based on the“Surveillance for common disease and health risk factors among students project”,a stratified random cluster sampling method was used to collect 45 595 students aged 7 to 17 from 26 counties(cities or districts)of 13 cities in Jiangsu Province. BMI percentile reference values for children and adolescents in Jiangsu Province were obtained by using the skewness - median - coefficient of variation method(LMS method). The corresponding percentile curves were fitted and compared with the national level. Results:The BMI of boys and girls aged 7 to 17 in Jiangsu Province increased with age. Boys’BMI entered the growth peak at the age of 9,slowed down after the age of 12;girls’BMI entered the growth peak at the age of 10,and slowed down after the age of 14. The 5 th, 50 th,and 95 th BMI percentiles of children and adolescents in Jiangsu Province were higher than the national level throughout the age range. Conclusion:This study presents the distribution of BMI among children and adolescents in Jiangsu Province. BMI percentile reference values and growth curves of children and adolescents in Jiangsu Province were obtained based on the LMS method,and the fitting effect was good. The main percentiles of BMI for boys and girls in all age groups in Jiangsu Province were higher than the national level,and the median BMI of boys in each age group was higher than that of girls.
