Women Who Drink Alcohol Close to Pregnancy Less Likely to Take Multivitamins

A new study finds that women who drink alcohol before pregnancy may be less likely to take multivitamins.

According to researchers from the University of California, San Diego Department of Pediatrics and Rady Children's Hospital-San Diego, a research affiliate of UC San Diego School of Medicine, they have found a common link between multivitamin use and alcohol consumption during pregnancy. This information uncovered a need for education about the importance of vitamin supplementation, particularly among women who drink alcohol during their childbearing years.

Researchers looked at data from the Centers for Disease Control and Prevention's multiple-state Pregnancy Risk Assessment Monitoring System (PRAMS) of more than 100,000 women between 2004 and 2008. The women answered a series of questions involving their alcohol use before pregnancy as well as multivitamin consumption during. The study found women who reported consuming alcohol regularly or binge drinking were significantly less likely to take a multivitamin supplement compared with those who did not report alcohol consumption.

"It's likely a woman may consume alcohol before she even realizes she's pregnant, therefore, these findings are significant," explained Lauren Bartell Weiss, PhD, a postdoctoral research fellow at UC San Diego's Center for the Promotion of Maternal Health and Infant Development and co-author of the study. "If a woman is drinking alcohol regularly and unintentionally becomes pregnant, not only does her unborn child have a greater risk of being affected by the alcohol, but other studies suggest that alcohol can also alter the metabolism of nutrients and interfere with the nutritional supply to the developing baby."

Since pregnancy increases the demand for several vitamins and minerals in order to adequately support a developing fetus, Weiss said the alcohol interference with nutritional supply means a woman's unborn child may also have a greater risk of developing other birth defects, such as neural tube defects, if she hasn't been taking a multi-vitamin.

"These findings emphasize the need for educating all women of childbearing age, especially those who drink alcohol, about the importance of taking multivitamins regularly whether they're planning to have children or not," said Weiss.
