研究背景1999 - 2006年，美国儿童和青少年高体重指数（BMI）的患病率趋于平稳。目的提供儿童和青少年高BMI和婴儿和幼儿高体重的最新估计值，并分析1999 - 2008年患病率的趋势。设计，设置，2007-2008年全国健康和营养检查调查，对3281名儿童和青少年的身高和体重进行测量，（2至19岁）和719名婴幼儿主要结果测量平卧位高体重的患病率（>=疾病控制和预防中心生长图表的第95百分位数）。儿童和青少年中高BMI的患病率定义为3个水平：年龄BMI ≥第97百分位数、≥第95百分位数和≥第85百分位数。结果2007-2008年，9.5%的婴幼儿（95%可信区间[CI]，7.3%~ 11.7%）的身高在95百分位数以上。在2至19岁的儿童和青少年中，（95% CI，9.8%-13.9%）等于或高于年龄BMI生长图表的第97百分位数; 16.9%（95% CI，14.1%-19.6%）等于或高于BMI的第95百分位数; 31.7%（95% CI，29.2%-34.1%）等于或高于BMI的第85百分位数。患病率估计值因年龄和种族/族裔群体而异。趋势分析表明，1999-2000年和2007-2008年之间没有显著的趋势，除了最高的BMI分界点所有6- 19岁男孩的BMI（年龄>=第97百分位数）（比值比[OR]，1.52; 95%CI，1.17-2.01），在同龄的非西班牙裔白色男孩中，（OR，1.87;结论在1999-2000年期间，没有发现高体重与卧位长度或高BMI的统计学显著线性趋势，2001-2002年、2003-2004年、2005-2006年和2007-2008年，女孩和男孩的死亡率分别为10%、20%和20%，但6至19岁最重的男孩除外。JAMA. 2010;303（3）：242-249
Context The prevalence of high body mass index (BMI) among children and adolescents in the United States appeared to plateau between 1999 and 2006.Objectives To provide the most recent estimates of high BMI among children and adolescents and high weight for recumbent length among infants and toddlers and to analyze trends in prevalence between 1999 and 2008.Design, Setting, and Participants The National Health and Nutrition Examination Survey 2007-2008, a representative sample of the US population with measured heights and weights on 3281 children and adolescents (2 through 19 years of age) and 719 infants and toddlers (birth to 2 years of age).Main Outcome Measures Prevalence of high weight for recumbent length (>= 95th percentile of the Centers for Disease Control and Prevention growth charts) among infants and toddlers. Prevalence of high BMI among children and adolescents defined at 3 levels: BMI for age at or above the 97th percentile, at or above the 95th percentile, and at or above the 85th percentile of the BMI-for-age growth charts. Analyses of trends by age, sex, and race/ethnicity from 1999-2000 to 2007-2008.Results In 2007-2008, 9.5% of infants and toddlers (95% confidence interval [CI], 7.3%-11.7%) were at or above the 95th percentile of the weight-for-recumbent-length growth charts. Among children and adolescents aged 2 through 19 years, 11.9% (95% CI, 9.8%-13.9%) were at or above the 97th percentile of the BMI-for-age growth charts; 16.9% (95% CI, 14.1%-19.6%) were at or above the 95th percentile; and 31.7% (95% CI, 29.2%-34.1%) were at or above the 85th percentile of BMI for age. Prevalence estimates differed by age and by race/ethnic group. Trend analyses indicate no significant trend between 1999-2000 and 2007-2008 except at the highest BMI cut point (BMI for age >= 97th percentile) among all 6-through 19-year-old boys (odds ratio [OR], 1.52; 95% CI, 1.17-2.01) and among non-Hispanic white boys of the same age (OR, 1.87; 95% CI, 1.22-2.94).Conclusion No statistically significant linear trends in high weight for recumbent length or high BMI were found over the time periods 1999-2000, 2001-2002, 2003-2004, 2005-2006, and 2007-2008 among girls and boys except among the very heaviest 6-through 19-year-old boys.
