Effect of Oral Daily Supplementation With 400 IU Vs 200 IU of Vitamin D in Term Healthy Neonates

Vitamin D deficiency is highly prevalent in India as reported in various studies. Vitamin D supplementation is necessary as vitamin D is required not only for prevention of rickets as traditionally thought, but also for its emerging role in development of diseases such as myopathic disorders, proneness to infection, autoimmune disorders and cancers .However supplementation studies are limited and predominantly from foreign countries. Moreover most of them report variable outcomes with no unanimous outcome with respect to optimum dose and duration of supplementation of vitamin D. Various national authorities recommend different doses of vitamin D for supplementation. American Academy of Pediatrics, The Institute of Medicine of National Academics, The Drug and Therapeutics Committee of the Lawson Wilkins Pediatric Endocrine Society, the Canadian Pediatric Society and European Society for Pediatric Endocrinology recommend that 400IU of vitamin D should be supplemented in all infants starting from within a few days of birth throughout childhood. ESPGHAN recommends 800-1000 IU for high risk infants, Ireland recommends 200IU vitamin D per day, UK does not recommend any supplements upto 6 months of age , however if formula milk intake <500ml/day then 300 IU is recommended. There are no such guidelines for India. Hence this study aims at evaluating the proportion of vitamin D deficient
