ObjectiveTo study the association between asthma control and serum 25OH Vitamin D levels in children with moderate persistent asthma on preventer therapy.MethodsChildren aged 6–18 years, with moderate persistent asthma, on preventer therapy for ≥2 months were included. Control was categorized as good, partial or poor as per GINA guidelines. Serum 25 (OH) Vitamin D levels were measured and their relationship with the level of control was studied.ResultsOut of 50 children enrolled, 22 had well-controlled asthma, and 21 had partially controlled asthma. Vitamin D was deficient in 30 children and insufficient in 18 children. Children with vitamin D deficiency had significantly less wellcontrolled asthma as compared to those with insufficient or sufficient levels of 25 (OH) vitamin D (13.3% vs 88.9 % vs 100%).ConclusionVitamin D deficiency is associated with suboptimal asthma control.
