This study investigated whether residential availability of natural outdoor environments (NOE) was associated with contact with NOE, overall physical activity and physical activity in NOE, in four different European cities using objective measures. A nested cross-sectional study was conducted in Barcelona (Spain); Stoke-on-Trent (United Kingdom); Doetinchem (The Netherlands); and Kaunas (Lithuania). Smartphones were used to collect information on the location and physical activity (overall and NOE) of around 100 residents of each city over seven days. We used Geographic Information Systems (GIS) to determine residential NOE availability (presence/absence of NOE within 300 m buffer from residence), contact with NOE (time spent in NOE), overall PA (total physical activity), NOE PA (total physical activity in NOE). Potential effect modifiers were investigated. Participants spent around 40 min in NOE and 80 min doing overall PA daily, of which 11% was in NOE. Having residential NOE availability was consistently linked with higher NOE contact during weekdays, but not to overall PA. Having residential NOE availability was related to NOE PA, especially for our Barcelona participants, people that lived in a city with low NOE availability.
本研究使用客观测量方法，调查了欧洲四个不同城市中自然户外环境（NOE）的居住可及性是否与接触NOE、总体身体活动以及在NOE中的身体活动相关。在西班牙的巴塞罗那、英国的特伦特河畔斯托克、荷兰的多廷赫姆以及立陶宛的考纳斯进行了一项嵌套横断面研究。使用智能手机收集了每个城市约100名居民在七天内的位置和身体活动（总体和在NOE中的活动）信息。我们使用地理信息系统（GIS）来确定居住的NOE可及性（住所300米缓冲区内是否存在NOE）、与NOE的接触（在NOE中花费的时间）、总体身体活动（总身体活动量）、NOE中的身体活动（在NOE中的总身体活动量）。对潜在的效应修饰因素进行了调查。参与者每天在NOE中花费约40分钟，进行总体身体活动的时间为80分钟，其中11%是在NOE中进行的。居住有NOE可及性与工作日期间更高的NOE接触始终相关，但与总体身体活动无关。居住有NOE可及性与在NOE中的身体活动相关，特别是对于我们巴塞罗那的参与者，即那些生活在NOE可及性较低城市的人。
