correlation between vitamin d status in mothers and their neonates in an iranian population

background and objective: there has been a resurgence of nutritional rickets in children in many developing countries. furthermore, vitamin d deficiency is one of the major health problems and unexpectedly has a high prevalence in sunny countries (e.g. middle east). in order to find out the association between vitamin d deficiencies in mothers and their neonates, we designed this study. methods: in a cross-sectional study, 49 pregnant women were recruited from ali-asghar children’s hospital in tehran, in 2015. all blood samples were assayed for 25-hydroxyvitamin d3, calcium, phosphorus, parathyroid hormone, alkaline phosphatase and creatinine. vitamin d deficiency defined as levels of 25(oh) d < 20 ng/ml for mothers and newborns. results: the mean±sd 25ohd levels of the mothers and their neonates were 26.1±8.44 ng/ml and 17.23 ±10.36 ng/ml, respectively. serum 25ohd of the mothers and their neonates were significantly correlated (r = 0.446, p< 0.001). conclusion: we found a significant correlation between vitamin d deficiency in mothers and their neonates. we think it is necessary to reconsider the recommendation of vitamin d supplementation for women during pregnancy.
