A recent study from Norway determined that by the end of pregnancy, 1 in 3 women are deficient in vitamin D.1 During the winter, when the days are much darker, this percentage rose to nearly 50 percent.

Lead author adds, “use of sunscreen during the summer months further inhibits vitamin D production”

The study’s lead author points out that “It’s tough to get enough vitamin D from dietary sources, and for 6 months of the year the sunlight isn’t sufficient at northern latitudes for our skin to make the vitamin. Even though we see the sun, it’s too low for us to produce vitamin D.” She adds that the use of sunscreen during the summer months further inhibits vitamin D production.

Vitamin D status during pregnancy can have significant repercussions. Two specific outcomes addressed in this study were bone mass and risk of childhood asthma.

Vitamin D crucial for bone mass

Low vitamin D levels can significantly affect bone health of the child as well as the mother. Vitamin D is crucial for the absorption and utilization of calcium. In pregnancy, this becomes even more important because the skeletal system of the baby is being created, as well as the one of the mother maintained. Previous studies have shown that offspring of vitamin D deficient mothers routinely have lower bone mass.

Childhood asthma

Vitamin D status during pregnancy has been shown to correlate not only to premature birth, but increased risk of childhood asthma. Supplementing vitamin D during pregnancy has been shown to reduce this risk. In addition, low levels of vitamin D have been seen to correlate with a higher risk of pre-eclampsia, and gestational diabetes.

Despite its known importance, it’s not uncommon for women not to receive recommendations regarding vitamin D supplementation

Despite the known benefits of vitamin D, and the health risks associated with low levels of the vitamin, it is not uncommon for women to not receive recommendations regarding vitamin D supplementation. The current study found that less than 20% of pregnant women were recommended to take vitamin D during pregnancy.
