创造或改善城市绿色空间有可能成为一种有效、可持续和深远的方式，可以增加人们的身体活动，改善人们的其他健康状况。然而，缺乏良好的自然实验研究来检验城市绿地变化对身体活动和健康的因果关系。这在老年人和英国尤其如此。本文描述了一项自然实验研究，以评估四种小规模城市街道绿化干预措施对老年人身体活动和健康的影响，为期一年，相对于八个匹配的比较地点。所有地点都位于英国大曼彻斯特的贫困城市社区。干预措施的组成部分包括植树和种花，以及人造树装饰。根据系统的匹配过程，选择了8个未改进的比较点，使用几个已知的客观和主观环境因素与老年人的身体活动相关。结果测量是使用新开发的观察工具收集的身体活动和其他两个健康行为指标（Connect：与其他人联系；Take Notice：注意环境）。主要的结果是注意行为，因为这种行为的最大影响是通过改善干预地点的绿色空间的美学质量来预期的。基线数据收集于2017年9月进行，随后于2017年11月安装干预措施。随访数据收集将于2018年2月/ 3月（6个月）和2018年9月（12个月）重复。本研究提供了一个难得的机会来评估在未充分研究的人口和环境中城市绿地的小规模变化的因果效应。虽然预计干预措施对结果的影响很小，但本研究通过解决先前自然实验研究中导致高偏倚风险的关键方法弱点，有助于发展该领域的自然实验方法。在本研究中，减少偏倚风险的关键改进是严格匹配多个比较点和适当的关键混杂因素的统计控制。回顾性注册，研究编号NCT03575923。注册日期：2018年7月3日。本文的在线版本（10.1186/s12889-018-5812-z）包含补充内容，仅供授权用户使用。
Creating or improving urban green space has the potential to be an effective, sustainable and far-reaching way to increase physical activity and improve other aspects of wellbeing in the population. However, there is a dearth of well-conducted natural experimental studies examining the causal effect of changing urban green space on physical activity and wellbeing. This is especially true in older adults and in the United Kingdom. This paper describes a natural experimental study to evaluate the effect of four small-scale urban street greening interventions on older adults’ physical activity and wellbeing over a 1-year period, relative to eight matched comparison sites. All sites are located in deprived urban neighbourhoods in Greater Manchester, United Kingdom. Components of the interventions include tree and flower planting, and artificial tree decorations. Eight unimproved comparison sites were selected based on a systematic process of matching using several known objective and subjective environmental correlates of physical activity in older adults. The outcome measures are physical activity and two other behavioural indicators of wellbeing (Connect: connecting with other people; and Take Notice: taking notice of the environment), collected using a newly developed observation tool. The primary outcome is Take Notice behaviour due to largest effects on this behaviour being anticipated from improvements in the aesthetic quality of green space at the intervention sites. Baseline data collection occurred in September 2017 before the interventions were installed in November 2017. Follow-up data collection will be repeated in February/ March 2018 (6 months) and September 2018 (12 months). The present study permits a rare opportunity to evaluate the causal effects of small-scale changes in urban green space in an understudied population and setting. Although the interventions are expected to have small effects on the outcomes, the present study contributes to developing natural experiment methodology in this field by addressing key methodological weaknesses causing high risk of bias in previous natural experimental studies. Key improvements to reduce risk of bias in the present study are rigorous matching of multiple comparison sites and appropriate statistical control of key confounders.
