More information is needed before physicians should start routinely screening pregnant women for vitamin D deficiency, according to an ACOG recently issued committee opinion statement.
More information is needed before physicians should start routinely screening pregnant women for vitamin D deficiency, the American College of Obstetricians and Gynecologists (ACOG) said in a recently issued committee opinion statement.
ACOG's Committee on Obstetric Practice writes that although evidence suggests that vitamin D deficiency is common during pregnancy-especially among women who are vegetarians, those with limited sun exposure, and minorities with darker skin-no consensus exists on the optimal level of vitamin D during pregnancy. Without that, routine screening is pointless.
For women thought to be at risk for vitamin D deficiency, maternal serum 25-hydroxyvitamin D levels can be helpful. If a deficiency is identified, most experts agree that 1,000 to 2,000 international units (IU) per day of vitamin D is safe; researchers have not studied sufficiently higher amounts during pregnancy.
In the end, the committee advises physicians that recommending that their pregnant patients take vitamin D supplementation during pregnancy beyond that contained in a prenatal vitamin is inappropriate until ongoing randomized clinical trials are completed.
