Past research has described positive associations between exposure to urban greenspaces and people's physical activity. However, there is variation in the relationship since it may differ according to the type of physical activity, socio-economic factors and use, as well as intrinsic characteristics of greenspaces. This study assesses the influence of urban greenspaces on distinct types of physical activity accounting for indicators such as vegetation quantity, tree cover density and green surface. The study combines data of a survey across Spain (n = 2063) with data derived from satellite imagery – including normalized difference vegetation indexes (NDVI), tree cover density and land-use cover data. A generalized linear mixed model was used to evaluate the association between urban greenspaces and physical activity as well as to evaluate the effect of main socio-economic determinants. After adjustment for potential confounders, greater availability in greenspace was found to be related with decreased sedentary time and increased walking. Besides exposure to urban greenspaces, physical activity was found to be associated with household income, pro-environmental attitudes, lifestyles and eating habits. The results also showed that exposure to greenspaces in rural areas had considerably weaker effect than in urban areas. The results suggest that efforts should be made to provide access to new greenspaces where possible, in order to foster walking and improve population health.

过去的研究已经描述了接触城市绿地与人们的体育活动之间的正相关关系。然而，这种关系存在差异，因为它可能因体育活动的类型、社会经济因素和用途以及绿地的内在特征而异。本研究根据植被数量、树木覆盖密度和绿地表面等指标评估了城市绿地对不同类型体育活动的影响。该研究将西班牙（n = 2063）调查数据与卫星图像数据相结合，包括归一化差异植被指数 (NDVI)、树木覆盖密度和土地利用覆盖数据。广义线性混合模型用于评估城市绿地与体育活动之间的关联，以及评估主要社会经济决定因素的影响。在对潜在混杂因素进行调整后，发现更大的绿地可用性与减少久坐时间和增加步行有关。除了接触城市绿地外，还发现身体活动与家庭收入、环保态度、生活方式和饮食习惯有关。结果还表明，农村地区绿地暴露的影响比城市地区要弱得多。结果表明，应努力在可能的情况下提供进入新绿地的机会，以促进步行并改善人口健康。在对潜在混杂因素进行调整后，发现更大的绿地可用性与减少久坐时间和增加步行有关。除了接触城市绿地外，还发现身体活动与家庭收入、环保态度、生活方式和饮食习惯有关。结果还表明，农村地区绿地暴露的影响比城市地区要弱得多。结果表明，应努力在可能的情况下提供进入新绿地的机会，以促进步行并改善人口健康。在对潜在混杂因素进行调整后，发现更大的绿地可用性与减少久坐时间和增加步行有关。除了接触城市绿地外，还发现身体活动与家庭收入、环保态度、生活方式和饮食习惯有关。结果还表明，农村地区绿地暴露的影响比城市地区要弱得多。结果表明，应努力在可能的情况下提供进入新绿地的机会，以促进步行并改善人口健康。环保态度、生活方式和饮食习惯。结果还表明，农村地区绿地暴露的影响比城市地区要弱得多。结果表明，应努力在可能的情况下提供进入新绿地的机会，以促进步行并改善人口健康。环保态度、生活方式和饮食习惯。结果还表明，农村地区绿地暴露的影响比城市地区要弱得多。结果表明，应努力在可能的情况下提供进入新绿地的机会，以促进步行并改善人口健康。
