Insufficient Vitamin D May Boost Asthma Risk
Children with insufficient vitamin D levels may be at higher risk of developing asthma, suggests a new study from equatorial Costa Rica.
Vitamin D levels were also associated with increased frequency of hospitalization, according to a study with 616 Costa Rican children with asthma published in the American Journal of Respiratory and Critical Care Medicine.
The researchers, led by John Brehm from Brigham and Women's Hospital and Harvard Medical School concluded: “In these children, lower vitamin D levels are associated with increased markers of allergy and asthma severity.”
