As green spaces are a common feature of liveable cities, a detailed understanding of the benefits provided by these areas is essential. Although green spaces are regarded as a major contribution to the human well-being in urbanized areas, current research has largely focused on the cities in developed countries and their global importance in terms of public health benefits remains unclear. In this study, we performed a multiple linear regression using 34 cities in different regions across the globe to investigate the relationship between green spaces and public health. Our analysis suggested that for richer cities, green spaces were associated with better public health; whereas a greater area of green spaces was associated with reduced public health in the poorest cities. In contrast to previous studies, which typically found positive relationships between green spaces and health benefits, we demonstrate that health benefits of green spaces could be context dependent.
由于绿色空间是宜居城市的共同特征，因此详细了解这些区域提供的益处至关重要。尽管绿色空间被认为是城市化地区人类福祉的主要贡献者，但当前的研究主要集中在发达国家的城市，其在全球范围内对公共卫生的重要性尚不清楚。在这项研究中，我们使用全球不同地区的 34 个城市进行了多元线性回归，以调查绿色空间与公共卫生之间的关系。我们的分析表明，对于较富裕的城市，绿色空间与更好的公共卫生相关；而在最贫穷的城市中，绿色空间的面积越大，公共卫生状况越差。与以往通常发现绿色空间与健康益处之间存在正相关关系的研究不同，我们证明绿色空间的健康益处可能取决于具体情况。
