背景：近一半的美国人不符合卫生部长的建议，即每天进行>= 30分钟的体力活动。一些公交用户可能每天仅通过步行往返公交来实现30分钟的身体活动。这项研究估计了每天步行往返交通的总时间，以及通过这样做实现每天30分钟体力活动的预测因素。方法：在2001年全国家庭旅行调查的105,942名成年受访者中，对3312名公交用户的公交相关步行时间进行了调查，美国交通部发起的一项基于电话的调查，旨在评估美国人的旅行行为。结果：使用交通工具的美国人每天步行往返交通工具的平均时间为19分钟; 29%的人每天仅通过步行往返交通工具来实现>= 30分钟的身体活动。在多变量分析中，轨道交通使用者、少数民族、年收入低于15，000美元的家庭以及人口密度高的城市地区的人更有可能每天步行往返于公共交通工具上; >= 30分钟。结论：步行往返于公共交通工具上可以帮助身体不活跃的人群，特别是低收入和少数民族群体，达到推荐的日常身体活动水平。增加使用公共交通的机会可能有助于促进和保持积极的生活方式。这项研究的结果可能有助于健康影响评估研究（HIA），评估拟议的公共交通系统对身体活动水平的影响，从而可能影响交通规划者的选择。
Background: Nearly half of Americans do not meet the Surgeon General's recommendation of >= 30 minutes of physical activity daily. Some transit users may achieve 30 minutes of physical activity daily solely by walking to and from transit. This study estimates the total daily time spent walking to and from transit and the predictors of achieving 30 minutes of physical activity daily by doing so.Methods: Transit-associated walking times for 3312 transit users were examined among the 105,942 adult respondents to the 2001 National Household Travel Survey, a telephone-based survey sponsored by the U.S. Department of Transportation to assess American travel behavior.Results: Americans who use transit spend a median of 19 minutes daily walking to and from transit; 29% achieve >= 30 minutes of physical activity a day solely by walking to and from transit. In multivariate analysis, rail users, minorities, people in households earning < $15,000 a year, and people in high-density urban areas were more likely to spend; >= 30 minutes walking to and from transit daily.Conclusions: Walking to and from public transportation can help physically inactive populations, especially low-income and minority groups, attain the recommended level of daily physical activity. Increased access to public transit may help promote and maintain active lifestyles. Results from this study may contribute to health impact assessment studies (HIA) that evaluate the impact of proposed public transit systems on physical activity levels, and thereby may influence choices made by transportation planners.
