人造环境和社会环境与身体活动有关。全球定位系统（GPS）和加速度计数据可以捕捉人们如何在环境中移动，并为更好地了解环境特征与身体活动之间的关系提供了有前途的工具。本研究的目的是在四个城市的成年人样本中研究gps衍生的建筑环境暴露与高士化特征和加速度计测量的身体活动之间的关系。我们使用了来自城市干预、研究和行动小组的第一波数据，这是一组生活在加拿大维多利亚、温哥华、萨斯卡通和蒙特利尔等城市的成年人。参与者的子样本在2017年5月至2019年1月期间佩戴了SenseDoc设备10天，以记录GPS和加速度测量数据。从SenseDoc数据中得出了两项体力活动结果：轻度、中度和剧烈体力活动的时间；以及花在适度或剧烈体育活动上的时间。使用相应的GPS坐标，我们通过传播区域（加拿大人口普查地理，代表400至700人居住的地区）和建筑（活跃的生活空间、便利设施的邻近性、城市紧凑性）和高绅化措施总结了体育活动的结果。我们使用多层级负二项回归模型检验了环境措施与身体活动结果之间的关系，该模型按城市分层，并调整了协变量（工作日/周末）、家庭传播区域、降水、温度)和调查中获得的参与者水平特征（年龄、性别、收入、种族）。我们发现，无论参与者住在哪里，成年人都花更多的时间在家附近、在更适合步行的环境和公园附近进行体育锻炼，而在城市紧凑地区花的时间更少。我们的分析还强调了不同城市与不同设施的接近程度与体育活动之间的关系。我们的研究深入了解了加拿大四个城市的建筑环境和中产阶级化特征与成年人花在体育锻炼上的时间之间的关系。这些发现增强了我们对环境随时间和空间对身体活动的影响的理解，并可以支持增加身体活动的政策。在线版本包含补充材料，可在10.1186/s12966-022-01306-z获得。
Built and social environments are associated with physical activity. Global Positioning Systems (GPS) and accelerometer data can capture how people move through their environments and provide promising tools to better understand associations between environmental characteristics and physical activity. The purpose of this study is to examine the associations between GPS-derived exposure to built environment and gentrification characteristics and accelerometer-measured physical activity in a sample of adults across four cities. We used wave 1 data from the Interventions, Research, and Action in Cities Team, a cohort of adults living in the Canadian cities of Victoria, Vancouver, Saskatoon, and Montreal. A subsample of participants wore a SenseDoc device for 10 days during May 2017–January 2019 to record GPS and accelerometry data. Two physical activity outcomes were derived from SenseDoc data: time spent in light, moderate, and vigorous physical activity; and time spent in moderate or vigorous physical activity. Using corresponding GPS coordinates, we summarized physical activity outcomes by dissemination area—a Canadian census geography that represents areas where 400 to 700 people live- and joined to built (active living space, proximity to amenities, and urban compactness) and gentrification measures. We examined the associations between environmental measures and physical activity outcomes using multi-level negative binomial regression models that were stratified by city and adjusted for covariates (weekday/weekend), home dissemination area, precipitation, temperature) and participant-level characteristics obtained from a survey (age, gender, income, race). We found that adults spent more time being physically active near their homes, and in environments that were more walkable and near parks and less time in urban compact areas, regardless of where participants lived. Our analysis also highlighted how proximity to different amenities was linked to physical activity across different cities. Our study provides insights into how built environment and gentrification characteristics are associated with the amount of time adults spend being physically active in four Canadian cities. These findings enhance our understanding of the influence that environments have on physical activity over time and space, and can support policies to increase physical activity.
