Urban green space and other recreational facilities are associated with physical activity. For adolescents living in multistory housing, public outdoor spaces that support physical activity may play an important role in activity promotion strategies. However, stronger evidence for a relation between the built environment and adolescent physical activity is scarce.
A natural experiment with a pre-experimental design was used with data collected in 2010 and 2012 before and after an urban renewal. Data were analyzed in 2016.
SETTING/PARTICIPANTS: Adolescents aged 11-16 years spending a minimum of 10 minutes daily within a 400-m buffer of the renewal district were included in the analyses, resulting in 354 adolescents at baseline and 319 post-renewal.
A multicomponent urban renewal project of approximately 35 million Euros in a disadvantaged neighborhood in the capital of Denmark occurred between 2010 and 2012.
The main outcomes were changes in time spent and physical activity within the area among adolescents, measured by accelerometry (ActiGraph GT3X) and GPS devices (Qstarz BT-Q1000XT).
Time spent in the area was greater in 2012 than 2010 with an additional 24.6 minutes per day (p=0.017). Of this time, 7.8 minutes were spent in light and 4.5 minutes in moderate to vigorous physical activity.
The present study indicates that a multicomponent urban renewal strategy in a disadvantaged district has the potential to increase time spent and physical activity in the district for adolescents living in or close to the district.
城市绿地和其他娱乐设施与身体活动有关。对于居住在多层住宅中的青少年来说，支持身体活动的公共户外空间可能在促进活动的策略中发挥重要作用。然而，关于建筑环境与青少年身体活动之间的关系，证据还不够强。
本研究采用自然实验设计，在城市更新前后（2010 年和 2012 年）收集数据，进行了一项预实验。数据分析于 2016 年进行。
地点/参与者：本研究纳入了在更新区 400 米缓冲区范围内每天至少花费 10 分钟的 11-16 岁青少年，其中基线时有 354 名青少年，更新后有 319 名。
丹麦首都一个贫困社区实施了一项约 3500 万欧元的多组分城市更新项目，该项目于 2010 年至 2012 年进行。
主要结果是通过加速度计（ActiGraph GT3X）和 GPS 设备（Qstarz BT-Q1000XT）测量的青少年在该地区的时间和身体活动的变化。
2012 年青少年在该地区的时间比 2010 年增加了 24.6 分钟/天（p=0.017）。其中，7.8 分钟用于轻度活动，4.5 分钟用于中等到剧烈身体活动。
本研究表明，在贫困地区实施多组分城市更新策略，有可能增加居住在或靠近该地区的青少年在该地区的时间和身体活动。
