肥胖和腹部肥胖与发病率和死亡率独立相关。体育活动会削弱这些风险。我们研究了1988年至2010年美国成年人的肥胖，腹部肥胖，体育锻炼和热量摄入趋势的趋势。
使用国家健康和营养检查调查（NHANES）数据进行单变量和多元分析。
男性和男性的平均身体质量指数（BMI）每年增加0.37％（95％CI，0.30-0.44％）。男女平均腰围增加了0.37％（95％CI，0.30-0.43％）和0.27％（95％CI，0.22-0.32％）。肥胖和腹部肥胖症的患病率大大增加，超重成年人的腹部肥胖症患病率也有所增加。年轻妇女的增长最大。未报告休闲时间体育锻炼的成年人比例从19.1％（95％CI，17.3-21.0％）增加到女性的51.7％（95％CI，48.9-54.5％），从11.4％（95％CI）男性为10.0-12.8％）至43.5％（95％CI，40.7-46.3％）。平均每日热量摄入量没有显着变化。 BMI和腰围趋势与体育活动水平相关，但无热量摄入量。与患有没有休闲时间的体育锻炼的男性相比，女性调整后的BMI相关变化的女性为8.3％（95％CI，6.9-9.6％），而没有休闲时间的男性中的1.7％（95％CI，0.68-2.8％）高度高。理想的休闲时间体育锻炼水平。
我们的分析强调了肥胖症公共卫生问题的重要方面，包括年轻妇女和腹部肥胖的趋势，以及对医学研究所对体育锻炼的重点的支持。
Obesity and abdominal obesity are independently associated with morbidity and mortality. Physical activity attenuates these risks. We examined trends in obesity, abdominal obesity, physical activity, and caloric intake in U.S. adults from 1988 to 2010. Univariate and multivariate analyses were performed using National Health and Nutrition Examination Survey (NHANES) data. Average body-mass index (BMI) increased by 0.37% (95% CI, 0.30-0.44%) per year in both women and men. Average waist circumference increased by 0.37% (95% CI, 0.30-0.43%) and 0.27% (95% CI, 0.22-0.32%) per year in women and men, respectively. The prevalence of obesity and abdominal obesity increased substantially, as did the prevalence of abdominal obesity among overweight adults. Younger women experienced the greatest increases. The proportion of adults who reported no leisure-time physical activity increased from 19.1% (95% CI, 17.3-21.0%) to 51.7% (95% CI, 48.9-54.5%) in women, and from 11.4% (95% CI, 10.0-12.8%) to 43.5% (95% CI, 40.7-46.3%) in men. Average daily caloric intake did not change significantly. BMI and waist circumference trends were associated with physical activity level, but not caloric intake. The associated changes in adjusted BMIs were 8.3% (95% CI, 6.9-9.6%) higher among women and 1.7% (95% CI, 0.68-2.8%) higher among men with no leisure-time physical activity compared to those with an ideal level of leisure-time physical activity. Our analyses highlight important dimensions of the public health problem of obesity, including trends in younger women and in abdominal obesity, and lend support to the emphasis placed on physical activity by the Institute of Medicine.
