Premature births lower in women taking folic acid

Women who take folic acid supplements for at least a year before becoming pregnant can greatly reduce their risk of delivering a baby prematurely, researchers said on Thursday. Folic acid, a B vitamin, already is known to prevent major birth defects that involve a baby's brain or spine. This study shows it may provide another benefit -- cutting down on premature births in which babies have less time to develop in the womb and are more likely to experience serious medical problems. The study tracked about 35,000 pregnant women between 1999 and 2002 who disclosed their folic acid intake. It found that women who took folic acid supplements for at least a year before pregnancy cut their chances for very early pre-term births -- 20 to 28 weeks into the pregnancy -- by 70 percent compared to other women. These very early pre-term babies in particular face a high risk of complications such as cerebral palsy, mental retardation, chronic lung disease and blindness. Women taking folic acid for at least a year before getting pregnant saw their risk fall by about 50 percent for premature births occurring 28 to 32 weeks into the pregnancy.

The findings were presented at a meeting of the Society for Maternal-Fetal Medicine in Dallas. Folic acid helps the body make healthy new cells. It is important for women to get enough of it before and during a pregnancy to prevent major birth defects called neural tube defects including spina bifida and anencephaly, experts say.

Bonnie - this is actually new information. The current recommendation was three months. I always suggest 6 months. Most of my clients are already on multivitamin as it is. But a higher dose one year prior to conception is a good idea.
