Abstract:
Objective Based on the existing observational evidence, the aim is to evaluate the relationship between green vegetation and cardiovascular and cerebrovascular events in adults and explore the potential mediating factors.
Methods Realated studies were retrieved in the Pubmed database from January 1, 2011 to February 20, 2022, and the articles were screened and the data were extracted according to inclusion criteria. Finally, the qualitative evaluation and meta-analysis were performed.
Results A total of fifty-five studies were included in the qualitative evaluation, of which seven were included in the quantitative analysis. Most studies showed that green exposure was negatively correlated with eight cardiovascular and cerebrovascular events. Partial meta-analysis results showed that the association between greenness and mortality of cardiovascular and cerebrovascular diseases was statistically significant. In addition, air quality and physical activity were the main mediators, followed by the noise and BMI.
Conclusion It is supported that increasing green vegetation can reduce the risk of cardiovascular and cerebrovascular events in adults, and further research on mediating factors is needed.
