Abstract
Vitamin D deficiency is a common problem in both developed and developing countries due to inadequate diet containing vitamin D and inadequate sunlight exposure. Breast milk also is poor in vitamin D and its metabolites. Vitamin D deficiency usually presents with bony deformities and the classical picture of rickets. It can also present without bone deformities but with symptoms of hypo- calcemia i.e. seizures, neuromuscular irritability, apnoea, stridor. Neonates born of mothers with low 25OHD levels will have a poor vitamin D status from the start and will be at increased risk of developing rickets. Several clinical works have proposed that vitamin D supplementation during pregnancy and at birth to term and preterm infants is important. In the current study, we aimed to determine prevalence of vitamin D deficiency in newborn infants of mothers in different risk groups.
