Doubling the number of women consuming vitamin supplement pills containing folic acid: An urgently needed birth defect prevention complement to the folic acid fortification of cereal grains

Abstract

The major known environmental causes of birth defects are ancient agents that have been in the environment for centuries but have been only recently discovered—rubella, alcohol, and folic acid deficiency. In the United States, we have made great progress in preventing congenital rubella syndrome. We also have a great opportunity to prevent spina bifida and anencephaly (SBA) by increasing the number of women who daily consume vitamin supplements containing folic acid. Even with the recently announced grain fortification regulations, there are 45 million women unprotected from an SBA-affected pregnancy. This article suggests that a substantial educational campaign could, over a 5-year period, double the number of women consuming folic acid supplement pills and make a substantial contribution toward preventing SBA.
