蒙古族7～18岁儿童青少年超重、肥胖者体质指数参考值的研究

目的 建立合理适用的蒙古族7 ～18岁儿童青少年超重、肥胖的体质指数(BMI)参考值标准.方法 取“全国学生体质健康调研”蒙古族通辽校点2000年的调查数据,有效人数为5 563人,以BMI为指标采用有序样品聚类分析方法对样本划分最优年龄段,再结合百分位数法确定超重、肥胖的界值点.结果 男女均划分为7～8岁、9 ～11岁、12 ～13岁、14～ 15岁、16～18岁共5个最佳年龄段,以每个年龄段的85百分位为超重的界值点,95百分位为肥胖的界值点,建立了蒙古族儿童青少年的BMI参考值标准,共计20个参考值.结论 该研究所建立的参考值标准针对蒙古族儿童青少年,突出了简单、实用的特点,可为蒙古族儿童青少年超重、肥胖的筛查、防治及临床诊断提供依据.

Establishment of a reasonable overweight and obese BMI reference standard of Mongolian children and adolescents aged 7 to 18

Objective To establish a reasonable overweight and obese body mass index （BMI） refer- ence standard of Mongolian children and adolescents, aged 7 to 18. Methods Data came from the survey of ＂National Students＇ Health Research Project＂ conducted in Tongliao Mongolian in 2000. Among the effective number of 5,563 in 2000, the subjects were divided with BMI as an indicator into optimal age groups by ordinal clustering methods. Then, the BMI reference as the age-specific percentile values were provided for evaluation of overweight and obesity. Results Both groups of girls and boys were divided into five age groups, 7 to 8, 9 to 11, 12 to 13, 14 to 15, 16 to 18 years old. By percentile cutoff values for overweight（85% ） and obesity （95%）, we established the Mongolian Children＇s BMI reference standards of 20 values altogether. Conclusion The standards established by this for Mongolian Children is simple and practical. It can be used in the overweight and obesity screen, prevention and clinical diagnosis.
