背景：年龄体重指数（BMI）已被推荐作为儿童和青少年过度肥胖的筛查试验。目的：我们通过使用与专家委员会建议一致的高肥胖定义，量化了美国具有全国代表性的人口样本中，与儿童和青少年总体高肥胖人群患病率相关的年龄bmi标准类别的表现。设计：1999-2004年，作为健康检查调查的一部分，采用双能x线吸收仪测量了8821名8-19岁儿童和青少年的体脂百分比。结果：采用几种不同的脂肪百分比临界值来定义高肥胖，大多数年龄bmi值高的儿童（>=生长图的第95百分位）为高肥胖，而年龄bmi值正常的儿童(
Background: Body mass index (BMI)-for-age has been recommended as a screening test for excess adiposity in children and adolescents.Objective: We quantified the performance of standard categories of BMI-for-age relative to the population prevalence of high adiposity in children and adolescents overall and by race-ethnic group in a nationally representative US population sample by using definitions of high adiposity that are consistent with expert committee recommendations.Design: Percentage body fat in 8821 children and adolescents aged 8-19 y was measured by using dual-energy X-ray absorptiometry in 1999-2004 as part of a health examination survey.Results: With the use of several different cutoffs for percentage fat to define high adiposity, most children with high BMI-for-age (>= 95th percentile of the growth charts) had high adiposity, and few children with normal BMI-for-age (
