Although a plethora of studies have investigated the association between green exposure and mental health in developed countries, it is only recently that academics and policymakers have paid attention to how this association works in rapidly urbanizing and developing countries. This study aims to explore biopsychosocial pathways linking residential greenness exposure to depression in the Chinese context using data from the 2016 wave of China Labour-force Dynamics Survey. Results from multilevel models along with mediation analysis show that exposure to residential greenness is negatively associated with depression, and that physical activity, stress and neighbourhood social cohesion altogether have a complete mediation effect on this association. Results from moderation analysis suggest that urbanicity moderates the relationship between greenness exposure and depression, and that the relationship is strongest at the upper level of urbanicity. Our findings suggest the necessity of increasing the provision of recreational green spaces and improving the quality of green spaces in Chinese less urbanized areas.
尽管大量研究已经调查了绿色暴露与发达国家心理健康之间的关系，但直到最近，学术界和政策制定者才开始关注这一关系在快速城市化和发展中国家的运作方式。本研究旨在利用 2016 年中国劳动力动态调查的数据，探讨在中国背景下将住宅绿化暴露与抑郁联系起来的生物心理社会途径。多层次模型和中介分析的结果表明，住宅绿化暴露与抑郁呈负相关，而身体活动、压力和邻里社会凝聚力共同对这种关系具有完全的中介作用。调节分析的结果表明，城市化程度调节了绿色暴露与抑郁之间的关系，并且这种关系在城市化程度较高的水平上最强。我们的研究结果表明，有必要在中国欠发达地区增加娱乐绿地的供应，并提高绿地的质量。
