Exposure to nature during the COVID-19 pandemic and the associated effect on mental health: a systematic review with meta-analysis

BACKGROUND: The COVID-19 pandemic and measures such as lockdowns to control its transmission generated unique effects on psychological health and well-being. In these circumstances, access to nature and outdoor spaces became a potentially important coping strategy, but the evidence exploring the mental health benefits of nature exposure during different stages of the pandemic is mixed and poorly understood. We systematically synthesised the evidence to examine larger trends in associations between nature exposure and mental health during the COVID-19 pandemic.

Urban Park Use During the COVID-19 Pandemic: Are Socially Vulnerable Communities Disproportionately Impacted?

The COVID-19 pandemic altered human behavior around the world. To maintain mental and physical health during periods of lockdown and quarantine, people often engaged in outdoor, physically distanced activities such as visits to parks and greenspace. However, research tracking outdoor recreation patterns during the pandemic has yielded inconsistent results, and few studies have explored the impacts of COVID-19 on park use across diverse neighborhoods. We used a mixed methods approach to examine changes in park use patterns in cities across North Carolina, USA, during the COVID-19 pandemic, with an emphasis on impacts in socially vulnerable communities (based on racial/ethnic composition and socioeconomic status). First, we surveyed a demographically representative sample of 611 urban residents during August 2020 to assess their use of outdoor park spaces before and during the pandemic. Second, we used cell phone location (i.e., geo-tracking) data to document changes in park visits within 605 socioeconomically diverse urban census tracts before (July 2019) and during (July 2020) the pandemic. Data from both methods revealed urban park use declined during the pandemic;56% of survey respondents said they stopped or reduced park use, and geo-tracked park visits dropped by 15%. Park users also became more homogenous, with visits increasing the most for past park visitors and declining the most in socially vulnerable communities and among individuals who were BIPOC or lower-income. Our results raise concerns about urban park use during the COVID-19 pandemic and suggest pre-existing health disparities in socially vulnerable communities might be exacerbated by inequitable access and utilization of parks and greenspace.

Cultural Cognition and Ideological Framing Influence Communication About Zoonotic Disease in the Era of COVID-19

Y The efficacy of science communication can be influenced by the cultural values and cognitions of target audiences, yet message framing rarely accounts for these cognitive factors. To explore the effects of message framing tailored to specific audiences, we investigated relationships between one form of cultural cognition-political ideology-and perceptions about the zoonotic origins of the COVID-19 pandemic using a nationally representative Qualtrics XM panel (n = 1,554) during August 2020. First, we examined differences in attitudes towards science (in general) and COVID-19 (specifically) based on political ideology. We found that, compared to conservatives and moderates, liberals trusted science more, were less skeptical of science, perceived greater risk from COVID-19, were more likely to believe in a wildlife origin of COVID-19, and were more likely to support restrictions on wildlife trade. Second, we examined the influence of cultural framing on the perceived validity of science related to COVID-19. Respondents were randomly assigned to one of three treatment groups: 1) a technocratic framing that highlighted feats of human ingenuity to overcome zoonoses;2) a regulatory framing that highlighted regulations and expansions of protected areas for wildlife as a means to prevent zoonoses, and 3) a control article about traffic lights with no cultural framing. After reading the initial framing article, all three groups read the same fictional, yet factually accurate, 'Nature Science study' generated by the authors. An OLS regression model revealed a significant interaction between the technocratic framing and political ideology. Relative to the control group, the technocratic framing slightly increased perceived validity of the Nature Science study for conservatives, significantly lowered perceived validity for liberals, and had no impact on moderates. We did not detect any significant interaction between framing and political ideology for the regulatory framing. Findings of this study highlight the need to account for cultural cognitions when communicating about COVID-19 and other zoonotic diseases. Communication strategies carefully designed to resonate with ideologically diverse audiences may ultimately lead to bipartisan support for actions required to promote "One Health" approaches that reduce the impacts of zoonoses on human and environmental health.
