Lack of vitamin D may cause asthma in some kids

June 23, 2010

The study in the Journal of Allergy and Clinical Immunology followed more than 1,000 children with asthma for four years. It found vitamin D insufficiency itself was linked to a 50 percent increase in the risk of severe asthma attacks.

But, at the same time, researchers found no evidence that vitamin D levels protected kids from moderate asthma symptoms.

Scientists say it's possible vitamin D's effect on the immune systems inflammatory response may be playing a role.
