Population-based studies of individual-level residential greenspace and mental health outcomes are still limited. Thus, the present study investigates greenspace-mental health associations-including depressive symptoms, burnout symptoms, and life satisfaction-in a population-based sample of adults, the Swedish Longitudinal Occupational Survey of Health, in 2016 ( = 14,641). High-resolution land cover of greenspace and green-blue-space was assessed at 50, 100, 300 and 500 m buffers around residential addresses. Higher residential greenspace and green-blue-space were associated with lower levels of depressive and burnout symptoms among non-working individuals and with higher life satisfaction in the whole study population, after controlling for age, sex, individual income, and neighborhood socioeconomics. The immediate residential-surrounding environment (50 m) consistently showed the strongest associations with the outcomes. Having a partner was associated with better mental health outcomes and with having more residential greenspace, and adjusting for this rendered greenspace-health associations mostly statistically non-significant. In conclusion, higher levels of greenspace and green-blue-space in the immediate residential-surrounding environment were associated with better mental health outcomes in the present study, which contributes additional nuances to prior studies. The importance of residential greenspace for public health, urban planning, and development is discussed.
基于人群的个体层面居住绿地与心理健康结果的研究仍然有限。因此，本研究在 2016 年的基于人群的成年人瑞典纵向职业健康调查中调查了绿地与心理健康之间的关联，包括抑郁症状、倦怠症状和生活满意度（n=14641）。在居住地址的 50、100、300 和 500 米缓冲区中评估了高分辨率的绿地和蓝绿空间土地覆盖。在控制年龄、性别、个人收入和社区社会经济状况后，居住绿地和蓝绿空间较多与非工作个体的抑郁和倦怠症状水平较低以及整个研究人群的生活满意度较高相关。直接的居住环境（50 米）与结果始终具有最强的关联。有伴侣与更好的心理健康结果以及更多的居住绿地相关，调整这些因素后，绿地与健康的关联在统计学上大多变得不显著。总之，本研究表明，直接的居住环境中较高水平的绿地和蓝绿空间与更好的心理健康结果相关，这为先前的研究增添了更多的细微差别。讨论了居住绿地对公共卫生、城市规划和发展的重要性。
