最近的报告显示，20世纪80年代和90年代青少年肥胖的快速增长已经趋于平稳。我们根据社会经济背景研究了美国12-17岁青少年肥胖的变化，使用了两项具有全国代表性的健康调查的数据，1988-2010年全国健康和营养调查和2003-2011年全国儿童健康调查。尽管总体肥胖流行率趋于稳定，但这一趋势掩盖了日益增长的社会经济梯度：近年来，高社会经济地位青少年的肥胖流行率有所下降，而低社会经济地位青少年的肥胖流行率却持续上升。另外的分析表明，体力活动水平的社会经济差异，以及卡路里摄入量的差异，可能导致了肥胖梯度的增加。
Recent reports suggest that the rapid growth in youth obesity seen in the 1980s and 1990s has plateaued. We examine changes in obesity among US adolescents aged 12-17 y by socioeconomic background using data from two nationally representative health surveys, the 1988-2010 National Health and Nutrition Examination Surveys and the 2003-2011 National Survey of Children's Health. Although the overall obesity prevalence stabilized, this trend masks a growing socioeconomic gradient: The prevalence of obesity among high-socioeconomic status adolescents has decreased in recent years, whereas the prevalence of obesity among their low-socioeconomic status peers has continued to increase. Additional analyses suggest that socioeconomic differences in the levels of physical activity, as well as differences in calorie intake, may have contributed to the growing obesity gradient.
