背景：超重（OW）在美国儿童的患病率在过去的三十年中有所增加，但患病率的措施未能揭示在何种程度上OW儿童超过OW threshold.OBJECTIVE：测量的金额，OW儿童超过OW阈值。使用测量的体重和身高数据来检查过去三十年该指标的趋势。设计、环境和参与者：用于分析的数据来自国家健康和营养检查调查（NHANES），对象为1971年至2000年2至19岁之间的人群。样本量为1999 - 2000年的4037例和1988 - 1994年的10590例。主要观察指标：OW程度是指每个儿童的体重指数（BMI）超过其年龄和性别特异性OW阈值的平均值。这一措施按性别、年龄组和种族/族裔进行审查。OW阈值为那些年龄在2 - 19岁的定义为在或以上的第95百分位数的性别特异性BMI的年龄growth charts.RESULTS：儿童OW的程度一直在增加速度比儿童OW的患病率在本文中考虑的所有分类，包括年龄，性别，种族和民族的分析。1971 - 1971年和1999 - 2000年之间，2 - 19岁的儿童OW的患病率增加了182%，而OW的程度增加了247%over the same time period.CONCLUSIONS：与患病率的措施，儿童OW的程度的措施是敏感的超重的BMI分布的变化。这项分析表明，在过去的三十年里，不仅有更多的儿童成为OW，而且OW儿童的体重也越来越重。
CONTEXT: The prevalence of overweight (OW) among children in the United States has increased during the last three decades, but prevalence measures fail to reveal the extent to which OW children exceed the OW threshold.OBJECTIVE: To measure the amount by which OW children exceed the OW threshold. To examine the trend in this measure over the last three decades using data with measured weights and heights.DESIGN, SETTING AND PARTICIPANTS: Data used for analysis are from the National Health and Nutrition Examination Survey ( NHANES) for persons between 2 and 19 y of age from 1971 to 2000. Anthropometric measures were obtained by trained health technicians, and the sample sizes range from 4037 in 1999 - 2000 to 10 590 in 1988 - 1994.MAIN OUTCOME MEASURE: The extent of OW is measured as the average amount by which each child's body mass index (BMI) exceeds their age and gender-specific OW threshold. This measure is examined by sex, age group and race/ethnicity. The OW threshold for those aged 2 - 19 y is defined as at or above the 95th percentile of the sex-specific BMI for age growth charts.RESULTS: The extent of child OW has been increasing faster than the prevalence of child OW for all classifications considered in this paper, including the analysis by age, sex, race and ethnicity. The prevalence of OW for children aged 2 - 19 y increased by 182% between 1971 - 1971 and 1999 - 2000, while the extent of OW increased by 247% over the same time period.CONCLUSIONS: Unlike prevalence measures, the measure of the extent of child OW is sensitive to changes in the BMI distribution of the overweight. This analysis reveals that not only have more children become OW in the last three decades, but OW children have been getting heavier.
