Keywords: vitamin D, pregnancy, neonate. Introduction Vitamin D deficiency in pregnancy is widespread in many parts of the world, 1 and there is an association between low vitamin D status and multiple potential adverse outcomes of pregnancy. Vitamin D sources and functions The major source of vitamin D is endogenous synthesis from epidermal stores of 7-dehy-drocholesterol following exposure of the skin to ultraviolet B radiation, resulting in formation of previtamin D 3 which is subsequently converted to vitamin D 3 cholecalciferol.
Open in a separate window. Figure 1. Vitamin D homeostasis and functions during pregnancy The classical function of vitamin D is to maintain calcium homeostasis. Table 1 Vitamin D status during pregnancy or at delivery: international variations. Implications of low vitamin D status during pregnancy Skeletal and calcemic complications It is generally accepted that maternal vitamin D deficiency can result in osteomalacia.
Extraskeletal and noncalcemic complications of vitamin D deficiency during pregnancy Several extraskeletal complications of vitamin D deficiency during pregnancy have been reported in the mother, fetus, and infant. Fetal growth The association between birth weight and maternal vitamin D status or intake remains inconclusive. Maternal complications Observational studies reported an association between maternal vitamin D status during pregnancy and development of pre-eclampsia, which has both a genetic and an immunologic pathogenesis.
Impact on neonate and infant Both in vitro and observational studies have demonstrated that vitamin D status during pregnancy impacts the immune response of the offspring. Conclusion The criteria for defining optimal vitamin D intake during pregnancy remain controversial.
