在美国，超过三分之一的成年人和17%的青年人肥胖，尽管在2003 - 2004年和2009 - 2010年之间，肥胖率保持稳定。提供儿童肥胖的最新全国估计，分析2003年至2012年儿童肥胖的趋势，并提供成年人肥胖趋势的详细分析。在2011 - 2012年全国代表性的国家健康和营养检查调查中，测量了9120名参与者的体重和身高或卧位长度。在婴儿和幼儿从出生到2岁，高体重的卧位长度被定义为体重的长度等于或高于第95百分位的性别特异性疾病控制和预防中心（CDC）的生长图表。在2至19岁的儿童和青少年中，肥胖定义为体重指数（BMI）等于或高于性别特异性CDC BMI年龄生长图表的第95百分位数。在成人中，肥胖定义为BMI大于或等于30。在5个时期（2003 - 2004年、2005 - 2006年、2007 - 2008年、2009 - 2010年和2011 - 2012年），按年龄分别对高体重的卧位长度或肥胖患病率的趋势进行了总体分析。在2011 - 2012年，8.1%（95% CI，5.8%-11.1%）的婴儿和幼儿有高体重卧位长度，16.9%（95% CI，14.9%-19.2%）的2 - 19岁儿童和34.9%（95% CI，32.0%-37.9%）的20岁或以上成人（年龄调整）肥胖。总体而言，从2003 - 2004年到2011 - 2012年，婴儿和幼儿的卧位体重、2 - 19岁儿童的肥胖或成人的肥胖没有显著变化。调查期间和年龄之间的相互作用的测试发现，儿童（P =.03）和妇女（P =.02）的相互作用。2至5岁儿童的肥胖率显著下降（从13.9%降至8.4%; P = 0.03），60岁及以上妇女的肥胖率显著增加（从31.5%降至38.1%; P = 0.006）。总体而言，2003 - 2004年和2011 - 2012年期间，青年或成年人的肥胖患病率没有显著变化。肥胖患病率仍然很高，因此继续监测很重要。
More than one-third of adults and 17% of youth in the United States are obese, although the prevalence remained stable between 2003–2004 and 2009–2010. To provide the most recent national estimates of childhood obesity, analyze trends in childhood obesity between 2003 and 2012, and provide detailed obesity trend analyses among adults. Weight and height or recumbent length were measured in 9120 participants in the 2011–2012 nationally representative National Health and Nutrition Examination Survey. In infants and toddlers from birth to 2 years, high weight for recumbent length was defined as weight for length at or above the 95th percentile of the sex-specific Centers for Disease Control and Prevention (CDC) growth charts. In children and adolescents aged 2 to 19 years, obesity was defined as a body mass index (BMI) at or above the 95th percentile of the sex-specific CDC BMI-for-age growth charts. In adults, obesity was defined as a BMI greater than or equal to 30. Analyses of trends in high weight for recumbent length or obesity prevalence were conducted overall and separately by age across 5 periods (2003–2004, 2005–2006, 2007–2008, 2009–2010, and 2011–2012). In 2011–2012, 8.1% (95% CI, 5.8%–11.1%) of infants and toddlers had high weight for recumbent length, and 16.9% (95% CI, 14.9%–19.2%) of 2- to 19-year-olds and 34.9% (95% CI, 32.0%–37.9%) of adults (age-adjusted) aged 20 years or older were obese. Overall, there was no significant change from 2003–2004 through 2011–2012 in high weight for recumbent length among infants and toddlers, obesity in 2- to 19-year-olds, or obesity in adults. Tests for an interaction between survey period and age found an interaction in children (P = .03) and women (P = .02). There was a significant decrease in obesity among 2- to 5-year-old children (from 13.9% to 8.4%; P = .03) and a significant increase in obesity among women aged 60 years and older (from 31.5% to 38.1%; P = .006). Overall, there have been no significant changes in obesity prevalence in youth or adults between 2003–2004 and 2011–2012. Obesity prevalence remains high and thus it is important to continue surveillance.
