Neighborhood green space and diabetes mellitus in Brazil.

Diabetes mellitus is a global public health concern, yet its association with neighborhood green space remains unexplored at a national scale in Brazil. This study analyzed the relationship between green space, measured via the Normalized Difference Vegetation Index (NDVI), and diabetes-related hospitalizations from 2008 to 2018. Using quasi-Poisson regression models, we assessed hospitalization data by sex and age group, incorporating air pollution, weather, and socioeconomic factors as covariates.

The mediating role of air pollution in the relationship between greenspace and cardiorespiratory admissions in Brazil.

Urban greenspaces have long been recognized for their potential to enhance environmental quality and public health. Despite the well-documented direct benefits of greenspaces, the mediating role of air pollution in the relationship between greenspaces and health outcomes remains less explored in low- and middle-income countries. This study investigates the mediating role of air pollution in the relationship between greenspace and cardiorespiratory admissions in Brazil.

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.

Weather impact on ambient air pollution and its association with land use types/activities over 5,572 municipalities in Brazil.

Quantify the impact of meteorological changes on air pollution levels is the aim of numerous recent studies. However, there is still a lack of investigations assessing the influence of land use/activities on the relationship between climate and air quality. In this study, we used a two-stage design to estimate the influence of land use types and activities on the association between weather changes and air pollution (PM, NO, SO, O) over 5572 municipalities in Brazil.

Thermal stress and hospital admissions for cardiorespiratory disease in Brazil.

The growing body of scientific literature underscores the intricate relationship between meteorological conditions and human health, particularly in the context of extreme temperatures. However, conventional temperature-centric approaches often fall short in capturing the complexity of thermal stress experienced by individuals. Temperature alone, as a metric, fails to encompass the entirety of the thermal stress individuals face, necessitating a more nuanced understanding.

Economic and racial disparities of the weather impact on air quality in Brazil.

Several studies have quantified the air pollution exposure disparities across racial and income groups. However, there is still a lack of investigations assessing disparities related to the impacts of weather on air pollution, which could indicate target air pollution reduction strategies under different climate scenarios. Our study aims to address this gap by estimating the economic and racial disparities of the weather impact on air quality in Brazil between 2003 and 2018.

The impact of wildfires on air pollution and health across land use categories in Brazil over a 16-year period.

Forest fires cause many environmental impacts, including air pollution. Brazil is a very fire-prone region where few studies have investigated the impact of wildfires on air quality and health. We proposed to test two hypotheses in this study: i) the wildfires in Brazil have increased the levels of air pollution and posed a health hazard in 2003-2018, and ii) the magnitude of this phenomenon depends on the type of land use and land cover (e.
