Folic acid and preconceptional care.
If all women capable of becoming pregnant consumed 400 µg (0.4 mg) of the B vitamin folic acid daily before conception and during the first trimester, the annual number of neural-tube birth defect (NTD)-affected pregnancies in this country could be reduced by 50% to 70%. Despite this important relationship, most women are not aware that folic acid prevents NTDs, and folic acid supplementation rates remain low. If folic acid consumption is to succeed as a public health intervention on a societal scale, physicians who care for reproductive-age women must become informed about the folic acid-NTD prevention linkage. Next, they must be encouraged to counsel patients about the need to consume sufficient folic acid before conception. Studies reveal that few physicians have adequate knowledge of the appropriate timing and dosage of folic acid supplementation. Studies also show that women are more likely to get important folic acid information not from their physicians but from other sources. This article provides information about ways in which physicians can improve their folic acid knowledge and education practices.
