Parents' stress may boost kids' asthma risk

July 21, 2009 Researchers say tense parents, combined with other known risk factors such as pollution, seem to increase a child's chance of developing the disease.

It's been known that women who are stressed in pregnancy are more likely to have a child who develops asthma or other allergies. Air pollution can promote inflammation of the airways and researchers say stress can also have pro-inflammatory effects. New research looks at that combination and how it may be affecting young bodies.

There is more on this study in the Proceedings of the National Academy of Sciences.
