Results of the studies on vitamin D provision to pregnant women and their newborn children are addressed. Vitamin D deficiency is highly prevalent in pregnant women and newborns. It was demonstrated that inadequate antenatal provision of a fetus with vitamin D may result in congenital rickets and neonatal seizures due to hypocalcemia in newborns and also accounts for increased rates of necrotic enterocolitis, bronchopulmonary dysplasia, and impaired growth and development as well as higher risk of lower respiratory tract infections (i.e., bronchiolitis, pneumonia) during the first year of a child’s life. In addition, it was shown that persistent vitamin D deficiency in future years may be associated with recurrent respiratory infections, allergic (e.g., atopic dermatitis, asthma, etc.), autoimmune, endocrine, and psycho-neurological disorders. Prev entive and therapeutic strategies for vitamin D deficiency in low birthweight preterm and full-term newborns since neonatal period are discussed.

Ul’yanov Cheboksary State University, Cheboksary, Russian Federation 7North State Medical University, Arkhangelsk, Russian Federation This paper reviews the effects of vitamin D deficiency on pregnant women and newborns. It was demonstrated that vitamin D deficiency in pregnant women is associated with higher risks of threatened preterm labor, placental insufficiency, preeclampsia, gestational diabetes, bacterial vaginosis, and impaired uterine contractility as well as higher rate of C-sections. Vitamin D insufficiency in newborns is associated with inadequate bone mineralization and also results in metabolic disorders, hypocalcemic seizures, bronchopulmonary dysplasia, necrotic enterocolitis, sepsis, mental and developmental disorders, and higher risks of various (infectious, allergic etc.) disorders. Optimal vitamin D dosing regimen in pregnant women and newborns is discussed.
