于 BMI 判定超重肥胖 4个标准的比较【摘要】目的比较 WGOC 标准、 WHO/NCHS 标准、 IOTF 标准、美国 CDC 标准判定超重肥胖的差异及能力,为与国外儿童青少年超重肥胖率进行比较以及促进儿童青少年超重肥胖预防措施的制定提供参考。方法应用 2005 年全国学生体质调研资料, 分析基于 BMI 判定超重、肥胖的 4 个标准的筛选差异; 以中国肥胖问题工作组公布的“中国学龄儿童超重、肥胖 BMI 筛查分类”参考标准作为“金标准”, 分别计算 WHO/NCHS 标准、 IOTF 标准、美国 CDC 标准的灵敏度、特异度以及符合率, 对比 3 种国际标准在我国儿童青少年中的适用性。结果在超重、肥胖的筛查能力方面, WHO 的标准具有较高的灵敏度、特异度, 符合率也最好。当需要与国外儿童青少年超重肥胖检出率进行比较时, WHO 标准更适用于我国儿童青少年超重肥胖的筛查。结论应用国际标准进行我国儿童青少年超重肥胖筛查时,需根据研究目的谨慎选择,以达到最佳的效果。【关键词】人体质量指数超重肥胖症参考标准学生保健 parison of Four BMI Criteria for Overweight and Obesity/ ZHANG Ji, MA Jun, LI Bai hui, et al.
