According to a report in Vanderbilt Medical Center's Reporter publication, a new study has linked use of prenatal vitamins before conception to reduced odds of miscarriage. The research will be published online this month in American Journal of Epidemiology.
In the study, researchers surveyed 4,800 moms about their vitamin usage and performed early ultrasounds to confirm their pregnancies. 524 of the moms miscarried. The majority of the moms in the study had planned their pregnancies in advance, and over 95% had used vitamins, and the moms who did not take prenatal vitamins were twice as likely to miscarry. The researchers suspect the reason is folic acid.
So is this study definite proof that prenatal vitamins can prevent miscarriages? Probably not, as far more research should be done before anyone would make such a claim, but the study does show that prenatal vitamin use may be statistically tied to a lower miscarriage rate. If you are not already taking prenatal vitamins, it can't hurt to start.
