目的通过分析2010年北京市学生体质健康调研结果,建立北京市儿童腰围筛查分类标准。方法按城乡、经济水平分层,调查北京市6个区40所中小学校和2所大学的7～22岁大中小学生8 795名。按照《2010年全国学生体质健康调研工作手册》规定的方法进行身体测量,以LMS法计算性别年龄别腰围各百分位数值,并绘制LMS曲线,建立北京市儿童青少年腰围正常值。结果北京市7～22岁男生腰围随年龄的增加而增大,女生在12岁以前呈现同样趋势,但之后趋于稳定。18岁男、女生腰围分别为76.62 cm和72.55 cm。不同BMI组别间腰围均值不同,肥胖组>超重组>正常组。北京市18岁男生超重/肥胖的腰围筛查标准是79.72 cm和89.31 cm,女生分别是74.38 cm和84.40 cm。结论LMS法建立的北京市儿童青少年腰围筛查标准准确,可以在北京地区推广使用。
