Folic acid pills may help prevent kids' speech delays: Study

Myth.  Well, this is partially true. According to the American Academy of Family Physicians, pregnant women should not be given vaccines for varicella (chicken pox) or MMR. But the inactivated flu vaccine is safe and even recommended for pregnant women, Dr. Brown says. During pregnancy, women's immune systems are compromised, making them more susceptible to infection. But many are not getting the flu shot; the CDC says that, at last estimate, only 11 percent of pregnant women got one. Dr. Brown says the shot triggers the mother's antibody production, protecting her baby through the first six months of life. More from Health.com: 12 vaccines your child needs

(CBS) A new study has parents-to-be talking. It suggests that women who take folic acid supplements early in pregnancy might help prevent language delays in their child.

It's not the first evidence suggesting that folic acid supplements are beneficial. Previous research suggested that folic acid supplements may prevent "neural tube" birth defects such as spina bifida. Women need 400 micrograms of folic acid each day, according to the CDC. Grains and other foods in the U.S. are often fortified with folic acid.

The study was done in Norway, because food there is not routinely foritied with folic acid, so the researchers wondered whether the availability of folic acid during early pregnancy could influence language development.

For the study - published in the Oct. 12 issue of the Journal of the American Medical Association - Norwegian researchers studied language kills of nearly 39,000 three-year-old children. Years earlier, the researchers had surveyed their mothers, asking whether they took supplements from 4 weeks before to 8 weeks after conception.

After accounting for other factors linked to speech delays like mom's weight and educational level, the researchers found of the 7,000 children whose mothers took folic acid supplements, 28 children had a severe language delay. Only 73 cases of severe language were found among the 19,000 children whose mothers took folic acid combined with other supplements. But for the 9,000 children whose parents took no supplements, 81 children had severe language delays.

"Clearly it plays a role in development that starts very early in pregnancy," Dr. Usha Ramakrishnan, an Emory University maternal and child nutrition researcher, who wasn't involved in the research, told Reuters.

Should moms start filling up on folic acid?

"We don't think people should change their behavior based on these findings," Dr. Ezra Susser, professor of epidemiology from Columbia University's Mailman School of Public Health in New York, told Reuters. "But it does add weight to the public health recommendation to take folic acid early in pregnancy."
