Contrary to earlier results, Vitamin D supplements do not prevent severe asthma attacks in at-risk children, according to the first placebo-controlled clinical trial to test this relationship.
“The reason that’s important is there are colleagues around this country and worldwide who are testing vitamin D levels for kids with asthma and giving them vitamin D,” said study lead author Juan C. Celedón, M.D., Dr.P.H., chief of pediatric pulmonary medicine at UPMC Children’s Hospital of Pittsburgh. “As a system, it costs a lot of money to run all these tests and give the supplements. We’ve shown no benefit for children with moderately low vitamin D levels.”
For three years, the Vitamin-D-Kids Asthma (VDKA) Study followed nearly 200 children ages 6 to 16 across seven different U.S. hospital systems. All had at least one asthma attack during the year before the study began.
