A new study points to persistent residential segregation, which traps minority children in unhealthy, polluted neighborhoods, to explain why black children are more likely to develop asthma.
In the United States, black children are twice as likely to develop asthma than other kids. Past research has pointed to low birth weight as a possible cause, but newer research says that though that may predispose children to asthma, it doesn’t cause the disease. Instead, a physical trigger is required.
Researchers couldn’t identify exactly what in neighborhoods triggers asthma, but speculate air pollution — indoor and outdoor — could be to blame.
