New Delhi: Children with prolonged vitamin D deficiency in the first decade of life are more likely to develop asthma and allergies, according to a new study. The study, published in the Journal of Allergy and Clinical Immunology, has found evidence of a clear link between a lack of vitamin D in early childhood and allergic disorders such as asthma and eczema. Children with vitamin D deficiency at six months of age were also more likely to experience two conditions previously associated with heightened asthma risk: increased harmful bacteria in the upper airways and increased susceptibility to severe lower respiratory infections involving fever.
“Vitamin D deficiency has been on the rise in developing countries because of increased indoor time and sun-avoidance measures.” Informs Dr Ramneek Mahajan, Director, Orthopedics & Joint Replacement, Max Smart Super Specialty Hospital, Saket, New Delhi.The sun is the best natural source of vitamin D, which is known to be important for lung function, lung development and immune function.
