Overview

• The study analyzed data from nearly 350,000 individuals in 14 cohorts across seven European countries, linking environmental exposures to asthma risk.
• Researchers found that 11.6% of asthma cases could be attributed to a combination of air pollution, urban density, and limited green spaces.
• Satellite imagery was used to assess environmental exposures, providing a comprehensive view of urban risk factors for asthma development.
• The findings highlight actionable opportunities for urban planners to reduce asthma incidence by improving environmental conditions in cities.
• Next steps include metabolome analysis of blood samples to understand the biological pathways linking environmental factors to asthma.
