Vitamin D Status is Inversely Associated with Anemia and Serum Erythropoietin during Pregnancy

Research has shown that Vitamin D and iron deficiencies frequently co-exist and potential overlapping metabolic pathways may need to be taken into account when designing programs. This study explored the links between iron and vitamin D status and their regulatory hormones in pregnant adolescents—a vulnerable group that is at risk of both vitamin D and iron deficiency. The findings indicated that vitamin D deficiency increases the risk of being anemic at delivery. Additional studies are needed to identify potential mechanisms that impact the relationship between vitamin D status and anemia. The authors recommended screening for multiple nutrient deficiencies during pregnancy to determine an appropriate course of action for prenatal supplementation.
