Dr. Chambers enrolled pregnant women who consumed moderate to heavy amounts of alcohol and comparison women who consumed no or low amounts of alcohol from two sites in Ukraine. They examined their nutritional status during pregnancy in blood samples, and compared their Vitamin D status to the recommended levels.
Overall, more than half of the women were deficient on Vitamin D, and women who were drinking alcohol were more likely to be deficient than those who did not, especially in the low sun seasons of the year.
Adequate Vitamin D is important for overall health and especially in pregnancy, so women whose pregnancies are already at risk of adverse outcomes due to alcohol use, may be at additional risk due to poor Vitamin D status. Vitamin D deficiency, if more prevalent in pregnant alcohol consumers, is one nutrient that could exacerbate the effects of alcohol on pregnancy outcomes.
Diet, supplements, and sun exposure interventions might help prevent pregnancy complications associated with Vitamin D deficiency. The full report is published in the Journal of the American College of Nutrition
