Physical activity confers considerable health benefits, but only half of U.S. adults report participating in levels of aerobic physical activity consistent with guidelines (1,2). Step It Up! The Surgeon General's Call to Action to Promote Walking and Walkable Communities identified walking as an important public health strategy to increase physical activity levels (3). A previous report showed that the self-reported prevalence of walking for transportation or leisure increased by 6 percentage points from 2005 to 2010 (4), but it is unknown whether this increase has been sustained. CDC analyzed National Health Interview Survey (NHIS) data from 2005 (26,551 respondents), 2010 (23,313), and 2015 (28,877) to evaluate trends in the age-adjusted prevalence of self-reported walking among adults aged ≥18 years. The prevalence of walking increased steadily among women, from 57.3% in 2005, to 62.5% in 2010, and to 65.1% in 2015 (significant linear trend). Among men, a significant linear increase in reported walking was observed, from 54.3% in 2005, to 61.8% in 2010, and to 62.8% in 2015, although the increase stalled between 2010 and 2015 (significant linear and quadratic trends). Community design policies and practices that encourage pedestrian activity and programs tailored to the needs of specific population subgroups remain important strategies for promoting walking (3).
体育活动能带来诸多健康益处,但只有一半的美国成年人报告称其参与的有氧运动水平符合指南要求(1,2)。“行动起来!” 美国卫生局局长促进步行及适宜步行社区的行动呼吁将步行确定为提高体育活动水平的一项重要公共卫生策略(3)。此前的一份报告显示,2005年至2010年期间,自我报告的因出行或休闲而步行的患病率上升了6个百分点(4),但目前尚不清楚这一增长是否持续。美国疾病控制与预防中心分析了2005年(26,551名受访者)、2010年(23,313名)和2015年(28,877名)的全国健康访谈调查(NHIS)数据,以评估18岁及以上成年人自我报告步行的年龄调整患病率趋势。女性步行的患病率稳步上升,从2005年的57.3%升至2010年的62.5%,并在2015年达到65.1%(显著线性趋势)。在男性中,报告的步行率也有显著线性增长,从2005年的54.3%升至2010年的61.8%,并在2015年达到62.8%,尽管在2010年至2015年期间增长停滞(显著线性和二次趋势)。鼓励行人活动的社区设计政策和做法以及针对特定人群亚组需求定制的项目仍然是促进步行的重要策略(3)。
