Abstract

CONTEXT

Between 1980 and 1999, the prevalence of adult obesity (body mass index [BMI] ≥30) increased in the United States and the distribution of BMI changed. More recent data suggested a slowing or leveling off of these trends.

OBJECTIVE

To estimate the prevalence of adult obesity from the 2009-2010 National Health and Nutrition Examination Survey (NHANES) and compare adult obesity and the distribution of BMI with data from 1999-2008.

DESIGN, SETTING, AND PARTICIPANTS: NHANES includes measured heights and weights for 5926 adult men and women from a nationally representative sample of the civilian noninstitutionalized US population in 2009-2010 and for 22,847 men and women in 1999-2008.

MAIN OUTCOME MEASURES

The prevalence of obesity and mean BMI.

RESULTS

In 2009-2010 the age-adjusted mean BMI was 28.7 (95% CI, 28.3-29.1) for men and also 28.7 (95% CI, 28.4-29.0) for women. Median BMI was 27.8 (interquartile range [IQR], 24.7-31.7) for men and 27.3 (IQR, 23.3-32.7) for women. The age-adjusted prevalence of obesity was 35.5% (95% CI, 31.9%-39.2%) among adult men and 35.8% (95% CI, 34.0%-37.7%) among adult women. Over the 12-year period from 1999 through 2010, obesity showed no significant increase among women overall (age- and race-adjusted annual change in odds ratio [AOR], 1.01; 95% CI, 1.00-1.03; P = .07), but increases were statistically significant for non-Hispanic black women (P = .04) and Mexican American women (P = .046). For men, there was a significant linear trend (AOR, 1.04; 95% CI, 1.02-1.06; P < .001) over the 12-year period. For both men and women, the most recent 2 years (2009-2010) did not differ significantly (P = .08 for men and P = .24 for women) from the previous 6 years (2003-2008). Trends in BMI were similar to obesity trends.

CONCLUSION

In 2009-2010, the prevalence of obesity was 35.5% among adult men and 35.8% among adult women, with no significant change compared with 2003-2008.

摘要

背景

1980 年至 1999 年间，美国成年人肥胖症（身体质量指数[BMI]≥30）的患病率上升，BMI 分布也发生了变化。最近的数据表明，这些趋势有所放缓或趋于平稳。

目的

根据 2009-2010 年全国健康与营养调查（NHANES）估计成年人肥胖症的患病率，并将成年人肥胖症和 BMI 分布与 1999-2008 年的数据进行比较。

设计、地点和参与者：NHANES 包括 2009-2010 年来自美国平民非机构化人口全国代表性样本的 5926 名成年男性和女性的身高和体重测量值，以及 1999-2008 年 22847 名男性和女性的身高和体重测量值。

主要观察指标

肥胖症和平均 BMI 的患病率。

结果

2009-2010 年，男性的年龄调整后平均 BMI 为 28.7（95%可信区间，28.3-29.1），女性也为 28.7（95%可信区间，28.4-29.0）。男性的中位数 BMI 为 27.8（四分位距[IQR]，24.7-31.7），女性为 27.3（IQR，23.3-32.7）。成年男性肥胖症的年龄调整患病率为 35.5%（95%可信区间，31.9%-39.2%），成年女性为 35.8%（95%可信区间，34.0%-37.7%）。在 1999 年至 2010 年的 12 年期间，女性整体肥胖症没有明显增加（年龄和种族调整后的优势比[AOR]每年变化 1.01；95%可信区间，1.00-1.03；P =.07），但非西班牙裔黑人女性（P =.04）和墨西哥裔美国女性（P =.046）的增长具有统计学意义。对于男性，在 12 年期间呈显著线性趋势（AOR，1.04；95%可信区间，1.02-1.06；P <.001）。对于男性和女性，最近的两年（2009-2010 年）与前六年（2003-2008 年）相比没有显著差异（男性 P =.08，女性 P =.24）。BMI 趋势与肥胖趋势相似。
