Children exposed to high levels of car-related air pollution are more likely to be readmitted to the hospital for asthma.
In a study of more than 700 kids hospitalized with asthma symptoms, 19 percent were readmitted within a year.
Researchers say white children who lived in polluted areas were three times more likely to be re-hospitalized than those who weren't exposed to much pollution.
There was no such association among African American children, although they had higher readmission rates overall. Researchers say this may mean other factors, like social stress or poor living conditions, are more relevant in minority populations.
