目的提供2009-2010年美国儿童和青少年肥胖率的最新估计，并调查1999-2000年和2009-2010年间儿童和青少年肥胖率和体重指数(BMI)的趋势。和参与者对美国儿童和青少年人口(出生到19岁)的代表性样本(N=4111)进行横断面分析，测量身高和体重来自2009-2010年的国家健康和营养检查调查。婴儿和学步儿童从出生到2岁的体重指数(BMI)为95%，2至19岁的儿童和青少年为肥胖(BMI=年龄增长指数的第95个百分位数)。结果2009-2010年间，9.7%(95%可信区间，7.6%~12.3%)婴幼儿和2~19岁儿童青少年肥胖(95%可信区间，15.4%~18.4%)。在2007-2008年和2009-2010年间，男性(P=.62)和女性(P=.65)的肥胖率没有差异。然而，12年的趋势分析表明，在1999年至2000年期间，肥胖患病率在2至19岁的男性中显著增加(优势比，20092010；95%可信区间，1.01-1.10)，但在女性(优势比，1.02；95%可信区间，0.98-1.07)中没有显著增加。12~19岁青春期男性BMI显著增加(P=.04)，其他各年龄段及女性BMI均无显著变化。结论2009~2010年儿童青少年肥胖患病率为16.9%，与2007~2008年相比无明显变化。贾玛2012年1月17日在线发布；307(5)：483-490。Doi：10.1001/jama.2012.40
Context The prevalence of childhood obesity increased in the 1980s and 1990s but there were no significant changes in prevalence between 1999-2000 and 2007-2008 in the United States.Objectives To present the most recent estimates of obesity prevalence in US children and adolescents for 2009-2010 and to investigate trends in obesity prevalence and body mass index (BMI) among children and adolescents between 1999-2000 and 2009-2010.Design, Setting, and Participants Cross-sectional analyses of a representative sample (N=4111) of the US child and adolescent population (birth through 19 years of age) with measured heights and weights from the National Health and Nutrition Examination Survey 2009-2010.Main Outcome Measures Prevalence of high weight-for-recumbent length (>= 95th percentile on the growth charts) among infants and toddlers from birth to 2 years of age and obesity (BMI >= 95th percentile of the BMI-for-age growth charts) among children and adolescents aged 2 through 19 years. Analyses of trends in obesity by sex and race/ethnicity, and analyses of trends in BMI within sex-specific age groups for 6 survey periods (1999-2000, 2001-2002, 2003-2004, 2005-2006, 2007-2008, and 2009-2010) over 12 years.Results In 2009-2010, 9.7% (95% CI, 7.6%-12.3%) of infants and toddlers had a high weight-for-recumbent length and 16.9% (95% CI, 15.4%-18.4%) of children and adolescents from 2 through 19 years of age were obese. There was no difference in obesity prevalence among males (P=.62) or females (P=.65) between 2007-2008 and 2009-2010. However, trend analyses over a 12-year period indicated a significant increase in obesity prevalence between 1999-2000 and 20092010 in males aged 2 through 19 years (odds ratio, 1.05; 95% CI, 1.01-1.10) but not in females (odds ratio, 1.02; 95% CI, 0.98-1.07) per 2-year survey cycle. There was a significant increase in BMI among adolescent males aged 12 through 19 years (P=.04) but not among any other age group or among females.Conclusion In 2009-2010, the prevalence of obesity in children and adolescents was 16.9%; this was not changed compared with 2007-2008.
