Dear Editor,

I read with great interest the study by Hakamifard et al.[1] published in January–February 2020 issue of the Journal of Medical Sciences. The authors studied the relationship between the frequency and severity of asthma attacks and Vitamin D (VD) levels among Indian children. They found no differences between patients with mild and moderate asthma in terms of the demographic variables, as well as there were no significant relationships between the severity of asthma and blood biochemistry factors. Serum VD level was 59.8 ng/ml in patients with mild asthma and 42.8 ng/ml in those with moderate asthma (P < 0.05). There was a negative relationship between VD and the severity of asthma.[1] They concluded that lower levels of VD increased asthma severity and recommended regular serum VD monitoring in asthmatic patients.[1] Based on the following limitation, I presume that the above-mentioned results and recommendation must be cautiously taken. It is worthy to mention that even in a tropical country like India, where there is plentiful sunshine, hypovitaminosis D (HVD) is widely distributed and it constitutes a substantial health problem among different age groups. The available data pointed out that the prevalence of HVD ranged from 84.9% to 100% among school-going children in India.[2] As female gender and older age are among numerous risk factors for HVD in the pediatric population,[3] I assume that conducting a case–control study involving cases group with asthma and age- and gender-matched control group is a better option to accurately address the role of VD in asthma.
