Greenness and Hospitalization for Cardiorespiratory Diseases in Brazil.

Background: The potential health benefits of exposure to vegetation, or greenness, are well documented, but there are few nationwide studies in Brazil, a country facing challenges related to land-use planning, deforestation, and environmental health risks.

Objectives: In this study, we investigated the association between greenness and hospitalizations for cardiorespiratory diseases in Brazil.

Methods: We accessed hospital admissions data from 967,771 postal codes (a total of 26,724,624 admissions) covering Brazil for the period between 2008 and 2018.
