Analysis on the BMI of Mongolian Students Aged 6-18 Years Old in 2005

目的了解2005年蒙古族6～18岁学生体重指数(BMI)分布特征,为改善学生健康状况提供依据。方法采用分层整群抽样方法,选择具有代表蒙古族集居区的通辽市的科左后旗、科尔沁区中的6所蒙古族中小学校及幼儿园,6～18岁学生,城乡各占50%,共3211名,对其体质指数分布特征进行统计分析。结果2005年蒙古族学生17岁前BMI指数总体随年龄增长呈现逐年增加趋势;17岁后在相对稳定的状态下有所起伏,其中有性别差异,青春期前后女生BMI指标低于男生,进入青春期后女生BMI指标明显高于男生。而城乡差异不明显,只有城乡男生16岁、城乡女生8岁差异有统计学意义。结论对蒙古族学生形态发育状况应引起高度重视,并应采取相应的综合防治措施。
