实用步行和休闲步行都有助于身体活动。然而，为了这两种目的而行走可能是不同的行为。我们试图提供实用步行和休闲步行的操作定义，并客观地衡量它们的行为、空间和时间差异，以便为交通和公共卫生政策和干预提供信息。研究人员从651名西雅图金县居民身上收集了2008-2009年的数据，这些居民佩戴了加速度计和GPS装置，并填写了7天的旅行日记。根据步行是否有目的地，将步行活动分为实用性和娱乐性。分析了两种步行目的之间的差异，并根据参与者的步行活动的嵌套结构进行了调整。在观察到的4,905次步行中，87.4%为功利步行，12.6%为休闲步行。与娱乐性步行比赛相比，实用性步行比赛的持续时间缩短45%（−12.1分钟），速度加快9% （+0.3km/h）。休闲步行在家庭社区发生的频率更高，与休闲土地使用无关。与休闲步行相比，功利步行发生在居住、就业和街道密度较高、住宅物业价值较低、混合用途社区目的地面积百分比较高、公园/步道百分比较低、平均地形坡度较低的地区。实用步行和休闲步行在频率、速度、持续时间、地点和相关的建筑环境等方面都有本质上的不同。促进步行的政策应该采用特定类型的策略。在家附近休闲步行的高发生率突出了家庭社区对这项活动的重要性。
Utilitarian and recreational walking both contribute to physical activity. Yet walking for these two purposes may be different behaviors. We sought to provide operational definitions of utilitarian and recreational walking and to objectively measure their behavioral, spatial, and temporal differences in order to inform transportation and public health policies and interventions. Data were collected 2008–2009 from 651 Seattle-King County residents, wearing an accelerometer and a GPS unit, and filling-in a travel diary for 7 days. Walking activity bouts were classified as utilitarian or recreational based on whether walking had a destination or not. Differences between the two walking purposes were analyzed, adjusting for the nested structure of walking activity within participants. Of the 4,905 observed walking bouts, 87.4% were utilitarian and 12.6% recreational walking. Utilitarian walking bouts were 45% shorter in duration (−12.1 min) and 9% faster in speed (+0.3km/h) than recreational walking bouts. Recreational walking occurred more frequently in the home neighborhood and was not associated with recreational land uses. Utilitarian walking occurred in areas having higher residential, employment, and street density, lower residential property value, higher area percentage of mixed-use neighborhood destinations, lower percentage of parks/trails, and lower average topographic slope than recreational walking. Utilitarian and recreational walking are substantially different in terms of frequency, speed, duration, location, and related built environment. Policies that promote walking should adopt type-specific strategies. The high occurrence of recreational walking near home highlights the importance of the home neighborhood for this activity.
