ABSTRACT

The study aimed to investigate the frequency of wheezing episodes in relation to vitamin D status in young children. Also, we explored factors associated with vitamin D deficiency and recurrent viral-induced wheeze episodes. Methods and Materials: The study enrolled 60 patients with episodic wheezing, 60 patients with recurrent wheezing, and 30 healthy individuals, all aged 6 months to 3 years. Serum vitamin D concentrations were measured in all study participants using electrochemiluminescence immunoassay. Results: Vitamin D deficiency was detected in 75% of recurrent wheezers and in 6.6% of children with episodic wheeze (P <.001). We registered an inverse relationship between the number of wheezing episodes and serum vitamin D concentrations. Children without vitamin D supplementation had substantially elevated odds of being found vitamin D deficient or recurrent wheezers. Other significant factors linked to recurrent wheezing were family history of allergy, maternal anemia during pregnancy, maternal active smoking currently. Conclusion: vitamin D deficiency and failed vitamin D supplementation are associated with the increased odds of recurrent wheezing in children of the first three years of life.
