确定2007年定义的重度（体重指数≥年龄和性别的第99百分位数）和病态（BMI ≥ 40 kg/m2）肥胖对不同美国儿童和青少年群体的影响程度，并随时间推移而增加。分析来自国家健康和营养检查调查（NHANES）II、III和1999-2004年的全国代表性数据; 12，384名2-19岁的美国儿童和青少年被纳入分析。结果指标为重度（BMI ≥第99百分位数）和病态（BMI ≥40 kg/m2）肥胖受试者的比例，年龄、性别、种族和贫困收入比（PIR）为关键变量。1999-2004年，3.8%的2-19岁儿童的BMI ≥第99百分位数，男孩的患病率高于女孩（4.6% vs. 2.9%; p<0.001）。黑人和墨西哥裔美国人的患病率最高，分别为5.7%和5.2%，而白人为3.1%（p< 0.001）。PIR类别的患病率也不同（PIR ≤3的患者为4.3%，PIR > 3的患者为2.5%; p = 0.002）。1.3%的12-19岁青少年BMI ≥40，与种族和贫困有类似的关系。自NHANES II（1976）以来，2-19岁儿童BMI ≥ 99百分位数的总体患病率增加了300%以上，自NHANES III（1994）以来增加了70%以上。在过去的25年里，儿童严重肥胖的比例增加了两倍，种族、性别和贫困程度存在显著差异。这对医疗保健和社区服务提出了要求，特别是因为儿童的发病率最高，他们经常得不到医疗保健系统的服务。
To determine the extent to which the 2007 definitions for severe (body mass index ≥99th percentile for age and gender) and morbid (BMI ≥ 40 kg/m2) obesity affects different groups of American children and adolescents and has increased over time. Analysis of nationally representative data from the National Health and Nutrition Examination Surveys (NHANES) II, III, and 1999–2004;12,384 US children and adolescents ages 2–19 years were included in the analysis. Outcome measures were the proportion of subjects with severe (BMI ≥99th percentile) and morbid (BMI ≥40 kg/m2) obesity, with age, gender, race, and poverty-income ratio (PIR) as key variables. In 1999–2004, 3.8% of children 2–19 yr had a BMI ≥99th percentile, with higher prevalence among boys than girls (4.6% vs. 2.9%; p<0.001). Prevalence was highest among Blacks, 5.7% and Mexican Americans, 5.2%, compared with Whites 3.1% (p< 0.001). The prevalence differed by PIR category as well (4.3% for those with PIR ≤3 vs. 2.5% for those with PIR > 3; p = 0.002). A BMI ≥40 was found in 1.3% of adolescents 12–19 yr, with similar associations with race and poverty. The overall prevalence of BMI ≥99th percentile has increased by more than 300% since NHANES II (1976), and over 70% since NHANES III (1994) in children 2–19 years of age. Rates of severe childhood obesity have tripled in the last 25 years, with significant differences by race, gender and poverty. This places demands on healthcare and community services, especially because the highest rates are among children who are frequently underserved by the health care system.
