陕西省青少年儿童BMI指数与美国、荷兰标准的比较

Comparison of Body Mass Index of Shaanxi Children and Adolescents With American, Hutch Standards.

【目的】 对陕西、美国、荷兰三地儿童青少年BMI指数 (bodymassindex)进行比较 ,分析BMI指数的地区差异 ,为儿童青少年超重、肥胖的评价标准的制定提供参考。 【方法】 采用LMS(λ Median coefficientofvariation)法拟合BMI指数百分位数 ,对三地BMI指数的偏度 (skewness ,L)、变异系数 (coefficientofvariation ,S)、中位数 (median ,M )和百分位数进行比较。 【结果】 陕西省儿童青少年BMI指数明显低于美国和荷兰 ,成年时 ,男女生分别低于美国 1.5 2～ 1.5 3kg/m2 和 0 .40～ 4.11kg/m2 ,低于荷兰 0 .3 4～ 0 .91kg/m2 和 0 .76～ 2 .12kg/m2 ,儿童青少年BMI指数的偏度、变异系数低于其它两地。 【结论】 陕西省儿童青少年体形的分布比较均匀 ,营养状况较其它两地差 ,因此不能用发达国家的标准评价我省儿童青少年的营养状况。

To investigate the difference of body mass index in children and adolescents among Shaanxi province of China, American and Dutch.Using LMS method fitting body mass index centiles, L(t), S(t), M(t) and centiles of body mass index were compared among different areas.There were significant difference among three areas, body mass index of children in Shaanxi were the lowest, at the age of 18, difference between Shaanxi and American were 1.52～2.53kg/m2 for boys and 0.40～4.11kg/m2 for girls, difference between Shaanxi and Dutch were 0.34～0.91kg/m2 for boys and 0.76～2.12kg/m2 for girls.[Conclusion]Shaanxi children's nutrition status was significant lower than that of American and Dutch, definition of overweight and obesity for children in developed country was not suitable for assessing nutrition status for children in developing country, especially for children in Shaanxi.
