A new study has disclosed that the lack of Vitamin D can worsen the symptoms of asthma in kids.

Study’s lead researchers Dr. Juan Celedon, Dr. P.H. and Dr. Augusto Litonjua, of Harvard Medical School showed that lower levels of vitamin D were linked with more serious asthma.

The researchers also said that kids with lack of vitamin D levels were considerably more likely to have been admitted to the hospital due to asthmatic attack, inclined to have airways with augmented hyperreactivity and were likely to have utilized more inhaled adrenal cortical steroids, all symptomatic of higher asthma harshness.

These kids were also significantly more likely to have a number of allergy markers that include dust-mite sensitivity.

Researchers said, “To our knowledge this is the first study to demonstrate an inverse association between circulating levels of vitamin D and markers of asthma severity and allergy.”

“While it is difficult to establish causation in a cross-sectional study such as this, the results were robust even after controlling for markers of baseline asthma severity,” they added.

Dr. Celedon said, “This study suggests that there may be added health benefits to vitamin D supplementation.”

To come to the conclusion, the researchers analyzed over 600 Costa Rican children aged between 6 and 14.

All the participants were inversely associated to various signs of allergic reaction and asthma severity.

The researchers said that the serum levels of vitamin D in the children were inversely associated to various indicators of allergic reaction and asthma severity.

Current advices for best possible vitamin D levels geared toward maintaining bone health, such as preventing rickets in kids and osteoporosis in grownups.

The researchers wrote, “This study also provides epidemiological support for a growing body of in vitro evidence that vitamin D insufficiency may worsen asthma severity, and we suspect that giving vitamin D supplements to asthma patients who are deficient may help with their asthma control.”

However, the researchers said that there is a need for further investigation to address the potential benefits of increasing vitamin D supplements for asthma patients.

The results of the study appear in ‘American Journal of Respiratory and Critical Care Medicine’.
