This study examined the association between access to quality urban green space and levels of physical activity.
A cross-sectional examination of the relationship between access to quality urban green space and level of recreational physical activity in 4950 middle-aged (40-70 years) respondents from the European Prospective Investigation into Cancer and Nutrition (EPIC), who resided in Norwich, UK.
Using geographic information systems (GIS), three measures of access to open green space were calculated based on distance only, distance and size of green space and distance, size and quality of green space. Multiple regression models were used to determine the relationship between the three indicators of access to open green space and level of recreational physical activity.
There was no evidence of clear relationships between recreational activity and access to green spaces. Non-significant associations were apparent for all variables, and there was no evidence of a clear trend in regression coefficients across quartiles of access for either the distance, size adjusted, and quality and size-adjusted models. Furthermore, the neighbourhood measures of access to green spaces showed non-significant associations with recreational physical activity.
Access to urban green spaces does not appear to be associated with population levels of recreational physical activity in our sample of middle-aged adults.
本研究探讨了获得优质城市绿地与身体活动水平之间的关联。
对来自欧洲癌症与营养前瞻性调查（EPIC）的4950名年龄在40至70岁之间、居住在英国诺维奇的受访者进行横断面研究，以考察获得优质城市绿地与休闲身体活动水平之间的关系。
使用地理信息系统（GIS），基于仅距离、距离和绿地面积以及距离、面积和绿地质量这三种方式计算了进入开放绿地的机会指标。采用多元回归模型来确定进入开放绿地的三个指标与休闲身体活动水平之间的关系。
没有证据表明休闲活动与获得绿地之间存在明确关系。所有变量的关联均不显著，并且在距离、面积调整以及质量和面积调整模型中，四分位数的进入机会指标的回归系数均无明显趋势。此外，邻里层面的绿地进入机会指标与休闲身体活动之间的关联也不显著。
在我们的中年成年人样本中，获得城市绿地似乎与休闲身体活动的人群水平无关。
