Traffic pollution may increase risk of allergies in children. In a German study, researchers have confirmed that they found a link between traffic pollution and childhood allergies.
Researchers stated that the children who lived within 50 meters from a busy road were 50 percent more likely to develop asthma, hay fever, eczema and other allergies than their counterparts living far away from such a road.
In the study, Joachim Heinrich, an epidemiologist at the Helmholtz Research Centre for Environment and Health in Munich and colleagues followed 3,00 healthy children in Munich for six years since birth for incidence of allergies and exposure to traffic pollution.
The researchers will continue to monitor the children over the next few years to see if any of the health problems can be reversed by moving to an area with less traffic.
The findings were published in the American Journal of Respiratory and Critical Care Medicine.
