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 (n = 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.

The objective of the current study was to investigate, for the first time, the association between individual-level residential greenspace and redemption of antidepressant drugs in a longitudinal nationwide population-based sample in Sweden. A nationwide population-based sample of adults residing in Sweden was studied during 2013–2016 (N_individuals = 108716; N_observations = 324378). Residential greenspace land cover was assessed via high resolution geographic information systems, at 50, 100, 300, and 500 m buffers around individual residences. Antidepressant redemptions were assessed through the Swedish National Prescribed Drug Register. Greenspace-antidepressant associations were analyzed using generalized estimating equations (GEE), adjusting for demographic, socioeconomic and urban factors. Higher greenspace within 50–500 m residential buffer zones was associated with lower levels of prevalent antidepressant redemptions (50 m, odds ratio [OR] 0.878; 100 m, OR 0.891; 300 m, OR 0.873; 500 m, OR 0.899), while only greenspace in the 50 m buffer was associated with incident antidepressant redemptions (OR 0.853), in covariate-adjusted models. In conclusion, residential greenspace is associated with statistically significantly lower prevalent and incident antidepressant medication redemptions. The association is particularly salient for greenspace in the closest buffer zone around the residence. The results underscore the importance of green infrastructure and greenspace in the immediate residential-surrounding environment for mental health, and further point towards the need for an environmental psychiatry framework, and the importance of integrating health and environmental policies, urban planning and greening.

Aim: The COVID-19 pandemic and associated restrictions posed challenges to people’s private and work lives. This included a rapid shift from on-site to remote work for many working adults in Sweden and internationally, and limited opportunities for indoor social and leisure activities. This involved risks for increased loneliness and social isolation, particularly among those mainly working remotely. In this context, nature visits may mitigate loneliness. This study adds to existing research in investigating whether a higher degree of remote work during COVID-19 was related to increased loneliness and whether nature visits mitigated loneliness, especially for those who mainly worked remotely. Subject and methods: The sample comprised a subsample of respondents to the Swedish Longitudinal Occupational Survey of Health 2020 (n = 984). Nature-related habits (NRH) were measured using self-reported frequency of visits to various natural environments. The effect of remote work, NRH, and time on loneliness (before – during COVID-19) was analyzed using linear mixed models while controlling for confounders. Results: Loneliness levels during COVID-19 were highest and increased the most compared to before the pandemic among individuals with the greatest degree of working remotely. Engaging daily in NRH was associated with lower loneliness levels, particularly among individuals mostly working remotely. This was observed in a three-way interaction effect between remote work, NRH, and time on loneliness. Conclusion: Daily nature visits may protect against loneliness during and beyond crises like COVID-19, particularly for those mainly working remotely. Policies preserving and facilitating access to nature may promote resilience during and beyond crises like COVID-19.

Aims: Spending time in natural environments has been linked to mental health benefits, and may have been an important resilience factor during the COVID-19 pandemic, but longitudinal studies are limited. This longitudinal study aimed to investigate the development of nature-related habits and their relationship to different mental health outcomes before and during early and later phases of COVID-19 (2019–2022). Furthermore, the buffering potential of nature-related habits on effects of major life events on mental health outcomes was investigated. Subject and methods: A subsample of the Swedish Longitudinal Occupational Survey of Health (SLOSH) was studied during 2018–2022, including follow-ups in early 2021 ( n   = 1902) and 2022 ( n = 1580). Visits to various types of nature, mental health outcomes (symptoms of depression, anxiety, loneliness, sleep difficulties), and major life events were analyzed across the study period while controlling for confounders. Results: Greater overall engagement in nature visits, particularly visiting forests or using one’s garden, was associated with lower levels of depression, anxiety, loneliness, and sleep problems in early 2021 and 2022. Importantly, changes in nature visits were consistently negatively associated with investigated mental health outcomes across the study period. All nature visits, except for garden time, increased in the long term (2019–2022). Visiting forests also increased in the short term, while overall nature visits initially decreased (2019–2020). Conclusion: Generally, nature visits increased longitudinally and were associated with better mental health outcomes during the COVID-19 pandemic. This underscores the importance of green- and blue-space accessibility for facilitating outdoor recreation in natural environments, to support resilience and public health during pandemics.
