Outline
To quantify the health benefits of simulated interventions to residential greenness exposure on the prevalence of hypertension (HTN), and to provide scientific evidence for the construction of a reasonable and effective healthy city planning system.
Based on the normalized difference vegetation index (NDVI) exposure levels at the county level in China, population distribution, and NDVI-HTN relative risk data, the Miettinen formula was used to evaluate the degree of reduction in HTN prevalence caused by equal amounts, static, dynamic and modified intervention NDVI.
The number of prevalent HTN cases decreased by 13.99% (13.97%-14.01%), 25.97% (25.92%-26.02%) and 36.00% (35.88%-36.11%)for every 0.10, 0.20, or 0.30 units increase of NDVI exposure in the study population. When NDVI was elevated to the maximum observation value (0.82) or above P75, 20.84% (17.11%-24.58%) and 6.21% (5.82%-6.59%) of HTN cases could be prevented.
All four greenness intervention schemes can reduce the prevalence of HTN. Among them, the equal intervention effect is better. In the future, a multi-dimensional and collaborative hypertension prevention and control strategy could be developed.
