Population Disparities in Asthma

Asthma disproportionately affects children, families with lower incomes and minorities. Racial and ethnic disparities in childhood asthma are extensive: African American and Puerto Rican children have high prevalence rates, and African American children have dramatically higher mortality rates. Puerto Ricans have the highest prevalence of asthma attacks. Research by EPA scientists leads to targeted improvements in public health and environmental outcomes.

Explore EPA asthma research in each of these descriptive posters that explains initial research questions, scientific method, findings, impacts and outcomes.



Cleaner Diesel Engines, Healthier Communities

Children and the elderly, especially those with asthma or other respiratory problems, are most sensitive to the health effects of diesel pollution. EPA's National Clean Diesel Campaign helps communities to reduce exposures to diesel exhaust and the amount of air pollution created by diesel school buses and other vehicles.
