| 探讨促进体力活动的建成环境干预措施对改善居民健康水平具有重要意义。基于2016和2019年开展的武汉东湖绿道周边小区居民的1 020份问卷跟踪调查数据，创新性地采用自然实验方法，探讨城市绿道与居民体力活动之间的因果关系，运用混合效应的logistics回归模型分析城市绿道干预对居民中高强度体力活动的影响及其剂量关系。研究发现，东湖绿道在1 km范围内显著提高了居民中高强度的体力活动水平，而且绿道对居民体力活动的影响存在显著的空间距离衰减效应。建议通过改善绿道可达性、完善周边邻里建成环境，促进居民体力活动和健康水平的提升。 |

| Abstract: |
| Improving built environment should be given higher priority in promoting physical activities and health status of the population. Two waves of survey data, before and after the intervention in 2016 and 2019 respectively, were collected from 1,020 participants in the neighborhoods around the East Lake Greenway in Wuhan, China. The natural experimental approach was adopted to explore the causal relationship between urban greenways and people’s physical activities. The mixed-effect logistics regression model was also applied to explore the intervention effect and dose-response effect of urban greenways on residents’ moderate-to-vigorous physical activities (MVPA). The results showed that greenways could significantly improve the MVPA of residents within one kilometer from the greenway, and a salient distance-decay effect of greenways on promoting physical activities was also observed. Our results suggest that the improvement of greenway accessibility and neighborhood environment deserves to be highlighted in promoting people’s physical activities and health status. |
