背景在19761980年至1988 - 1994年之间，在1988- 1994年至1999年之间，肥胖症的流行率在美国增加了。从20岁或20岁以上的5555名成年男女进行的设计，设置和参与者分析高度和体重测量2007 - 2008年作为国家健康和营养考试调查（NHANES）的一部分，这是美国人口的全国代表性样本。将来自20072008年获得的NHANE的数据与从1999年至2006年获得的结果进行了比较。成年人超重和肥胖症患病率的介绍估计值。超重定义为体重指数（BMI）为25.0至29.9。肥胖症的定义为30.0或更高的BMI。在2007 - 2008年的回归中，肥胖年龄调整的患病率为33.8％（95％置信区间[CI]，31.6％-36.0％），总体上为32.2％（95％CI CI男性中为29.5％-35.0％），35.5％（95％CI，女性中的33.2％-37.7％。超重和肥胖的相应患病率估计值（BMI> = 25）为68.0％（95％CI，66.3％-69.8％），72.3％（95％CI，70.4％-74.1％），和64.1％（95％）（95％ CI，61.3％-66.9％）。肥胖症患病率因年龄段而因男性和女人而异。在10年的时间里，肥胖症没有明显的趋势（调整后的比值比[AOR] 2007-2008 vs 1999-2000，1.12 [95％CI，0.89-1.32]）。对于男性来说，有很大的线性趋势（2007-2008 vs 1999-2000，1.32 [95％CI，1.12-1.58]）；但是，最近的3个数据点与彼此之间没有显着差异。在2007 - 2008年的判断中，成年男性的肥胖症患病率为32.2％，成年女性的患病率为35.5％。在过去的10年中，以前观察到的肥胖症患病率的升高似乎并没有以相同的速度持续，尤其是对于女性，可能是男性。贾马。 2010; 303（3）：235-241
Context The prevalence of obesity increased in the United States between 19761980 and 1988-1994 and again between 1988-1994 and 1999-2000.Objective To examine trends in obesity from 1999 through 2008 and the current prevalence of obesity and overweight for 2007-2008.Design, Setting, and Participants Analysis of height and weight measurements from 5555 adult men and women aged 20 years or older obtained in 2007-2008 as part of the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of the US population. Data from the NHANES obtained in 20072008 were compared with results obtained from 1999 through 2006.Main Outcome Measure Estimates of the prevalence of overweight and obesity in adults. Overweight was defined as a body mass index (BMI) of 25.0 to 29.9. Obesity was defined as a BMI of 30.0 or higher.Results In 2007-2008, the age-adjusted prevalence of obesity was 33.8% (95% confidence interval [CI], 31.6%-36.0%) overall, 32.2% (95% CI, 29.5%-35.0%) among men, and 35.5% (95% CI, 33.2%-37.7%) among women. The corresponding prevalence estimates for overweight and obesity combined (BMI >= 25) were 68.0% (95% CI, 66.3%-69.8%), 72.3% (95% CI, 70.4%-74.1%), and 64.1% (95% CI, 61.3%-66.9%). Obesity prevalence varied by age group and by racial and ethnic group for both men and women. Over the 10-year period, obesity showed no significant trend among women (adjusted odds ratio [AOR] for 2007-2008 vs 1999-2000, 1.12 [95% CI, 0.89-1.32]). For men, there was a significant linear trend (AOR for 2007-2008 vs 1999-2000, 1.32 [95% CI, 1.12-1.58]); however, the 3 most recent data points did not differ significantly from each other.Conclusions In 2007-2008, the prevalence of obesity was 32.2% among adult men and 35.5% among adult women. The increases in the prevalence of obesity previously observed do not appear to be continuing at the same rate over the past 10 years, particularly for women and possibly for men.
