瞄准提供2011-2012年美国20岁及以上成年人肥胖的全国估计值，并跟踪1999 - 2012年的趋势。方法.使用1999-2012年国家健康和营养检查调查的测量体重/身高来计算体重指数（BMI）和患病率。进行分段logistic回归以检验2010年前后的差异趋势。结果2011-2012年，年龄调整后的超重和肥胖患病率（BMI ≥ 25）为71.1%（95%置信区间：男子为68.0%-74.2%，女性肥胖率（61.8%-69.3%），男性肥胖率（BMI ≥ 30）为33.3%（30.5%-36.2%），女性肥胖率为35.8%（32.3%-39.4%）。从1990-2000年到2009-2010年，超重和肥胖合并、肥胖、2级和3级肥胖合并（BMI ≥ 35）和3级肥胖（BMI ≥ 40）的患病率分别增加了7.2%、17.8%、17.6%和33.0%。与2009-2010年相比，2011-2012年大多数按性别和种族/族裔分列的流行率指标保持不变或略有下降。2010年前后，流行率衡量指标之间的趋势没有显著差异。结论.同时，关于美国肥胖率趋于稳定的证据很少。鉴于其高流行率和深刻的社会经济后果，有必要密切监测这一趋势。
Aim. To provide national estimates of obesity among US adults aged 20 years and older in 2011-2012 and track its trends from 1999 to 2012. Methods. Measured weight/height from National Health and Nutrition Examination Survey 1999–2012 waves was used to calculate body mass index (BMI) and prevalence measures. Piecewise logistic regressions were conducted to test the differential trends before and after 2010. Results. In 2011-2012, the age-adjusted prevalence of overweight and obesity combined (BMI ≥ 25) was 71.1% (95% CI: 68.0%–74.2%) among men and 65.5% (61.8%–69.3%) among women, and the prevalence of obesity (BMI ≥ 30) was 33.3% (30.5%–36.2%) among men and 35.8% (32.3%–39.4%) among women. From 1990–2000 to 2009-2010, the prevalence of overweight and obesity combined, obesity, grades 2 and 3 obesity combined (BMI ≥ 35), and grade 3 obesity (BMI ≥ 40) increased by 7.2%, 17.8%, 17.6%, and 33.0%, respectively. Compared to 2009-2010, most gender- and race/ethnicity-specific prevalence measures remained unchanged or slightly decreased in 2011-2012. No significant difference in trends among prevalence measures was found before and after 2010. Conclusions. Concurrent evidence on the leveling off of obesity in the US is thin. Given its high prevalence and profound socioeconomic consequences, close monitoring of the trend is warranted.
