Objective: Asthma and obesity are important public health problems that affect millions of people in the world. Recently it has been shown that vitamin D may affect the prevalence of allergic disease and obesity. In this study, we evaluated the correlations between vitamin D, asthma, obesity and severity of asthma.
Materials and Methods: One hundred and nineteen subjects were included in the study. The study population consisted of four ageand sex-matched groups: Obese asthmatic children as group 1 (n:34), non-obese asthmatic children as group 2 (n:28), obese nonasthmatic children as group 3 (n:30) and non-obese non-asthmatic children as group 4 (n:27).
Results: There was no significant difference in serum vitamin D levels between groups. Also there was no difference between groups when we compared the serum vitamin D levels according to the severity of asthma.
Conclusion: There was no correlation between levels of serum vitamin D and presence of asthma and obesity.
