Provide the most recent data on the prevalence of obesity and severe obesity among United States children and adolescents aged 2 to 19 years.
The National Health and Nutrition Examination Survey, 1999-2014, was used. Weight status was defined using measured height and weight and standard definitions as follows: overweight as ≥85th percentile for age- and sex-specific BMI; class I obesity as ≥95th percentile; class II obesity as ≥120 of the 95th percentile, or BMI ≥35; and class III obesity as ≥140% of the 95th percentile, or BMI ≥40. This study reports the prevalence of obesity by 2-year National Health and Nutrition Examination Survey cycle and Wald tests comparing the 2011-2012 cycle with the 2013-2014 cycle, as well as the linear trend from 1999 to 2014. Multivariable logistic regression models estimated odds ratios for differences by each 2-year cycle.
In 2013-2014, 17.4% of children met criteria for class I obesity, including 6.3% for class II and 2.4% for class III, none statistically different than 2011-2012. A clear, statistically significant increase in all classes of obesity continued from 1999 through 2014.
There is no evidence of a decline in obesity prevalence in any age group, despite substantial clinical and policy efforts targeting the issue.
提供美国2至19岁儿童及青少年肥胖和重度肥胖患病率的最新数据。
采用1999 - 2014年国家健康与营养检查调查。根据测量的身高和体重以及以下标准定义体重状况：超重为年龄和性别特异性BMI≥第85百分位数；I类肥胖为≥第95百分位数；II类肥胖为第95百分位数的≥120%，或BMI≥35；III类肥胖为第95百分位数的≥140%，或BMI≥40。本研究报告了按国家健康与营养检查调查2年周期划分的肥胖患病率，以及比较2011 - 2012周期与2013 - 2014周期的Wald检验，以及1999年至2014年的线性趋势。多变量逻辑回归模型估计了每2年周期差异的比值比。
在2013 - 2014年，17.4%的儿童符合I类肥胖标准，其中II类肥胖为6.3%，III类肥胖为2.4%，与2011 - 2012年相比无统计学差异。从1999年到2014年，所有肥胖类别均持续出现明显的、具有统计学意义的上升。
尽管针对该问题进行了大量临床和政策努力，但没有证据表明任何年龄组的肥胖患病率有所下降。
