背景在过去的20年里，超重和肥胖的患病率在美国显著增加。目的使用最新的全国身高和体重测量数据，更新美国儿童超重和成人肥胖的患病率估计。设计、设置和参与者作为全国健康和营养检查调查（NHANES）的一部分，美国非制度化平民人口的复杂多阶段概率样本，在一九九九至二零零零年度，共有4115名成人及4018名儿童接受身高及体重量度，而在二零零一年，则有4390名成人及4258名儿童接受身高及体重量度。2002.主要结果测量超重的流行率（体重指数[BMI]大于或等于性别-年龄别BMI生长图表的第95百分位数）和超重流行率（BMI，25.0-29.9），肥胖（BMI大于或等于30.0）和极度肥胖按性别、年龄和种族/民族分类的成年人（BMI大于或等于40.0）。结果1999-2000年和2001-2002年间，成年人超重或肥胖的患病率没有显著变化，（64.5% vs 65.7%），肥胖（30.5%对30.6%），或极度肥胖（4.7%对5.1%），或6至19岁儿童中超重或超重（29.9% vs 31.5%）或超重（15.0% vs 16.5%）风险的患病率。总体而言，在1999 - 2002年至少20岁的成年人中，65.1%超重或肥胖，30.4%肥胖，4.9%极度肥胖。1999-2002年，在6至19岁的儿童中，31.0%有超重或超重的风险，16.0%超重。NHANES的结果表明，性别和种族/民族之间的超重和肥胖的患病率持续的差距。结论没有迹象表明，成人肥胖和儿童超重的患病率正在下降。儿童超重和成人肥胖的比例很高，仍然是一个重大的公共卫生问题。
Context The prevalence of overweight and obesity has increased markedly in the last 2 decades in the United States.Objective To update the US prevalence estimates of overweight in children and obesity in adults, using the most recent national data of height and weight measurements.Design, Setting, and Participants As part of the National Health and Nutrition Examination Survey (NHANES), a complex multistage probability sample of the US non institutionalized civilian population, both height and weight measurements were obtained from 4115 adults and 4018 children in 1999-2000 and from 4390 adults and 4258 children in 2001-2002.Main Outcome Measure Prevalence of overweight (body mass index [BMI] greater than or equal to95th percentile of the sex-specific BMI-for-age growth chart) among children and prevalence of overweight (BMI, 25.0-29.9), obesity (BMI greater than or equal to30.0), and extreme obesity (BMI greater than or equal to40.0) among adults by sex, age, and racial/ethnic group.Results Between 1999-2000 and 2001-2002, there were no significant changes among adults in the prevalence of overweight or obesity (64.5% vs 65.7%), obesity (30.5% vs 30.6%), or extreme obesity (4.7% vs 5.1%), or among children aged 6 through 19 years in the prevalence of at risk for overweight or overweight (29.9% vs 31.5%) or overweight (15.0% vs 16.5%). Overall, among adults aged at least 20 years in 19992002, 65.1% were overweight or obese, 30.4% were obese, and 4.9% were extremely obese. Among children aged 6 through 19 years in 1999-2002, 31.0% were at risk for overweight or overweight and 16.0% were overweight. The NHANES results indicate continuing disparities by sex and between racial/ethnic groups in the prevalence of overweight and obesity.Conclusions There is no indication that the prevalence of obesity among adults and overweight among children is decreasing. The high levels of overweight among children and obesity among adults remain a major public health concern.
