Are Women with Recent Live Births Aware of the Benefits of Folic Acid?

Abstract

Each year, approximately 4,000 pregnancies result in spina bifida or anencephaly, serious and often fatal conditions for the newborn. The B vitamin folic acid can reduce the incidence of these conditions by 50%-70%. To examine folic acid awareness among women who had recently delivered a live-born infant, CDC analyzed Pregnancy Risk Assessment Monitoring System (PRAMS) data for 1995-1998. The question used to measure awareness was, "Have you ever heard or read that taking the vitamin folic acid can help prevent some birth defects?" During the study period, overall folic acid awareness increased 15%, from 64% in 1996 to 73% in 1998, although changes varied by state. Despite this increase, differences in folic acid awareness were observed among different groups of women. Women who obtained a high school education or less; who were black, Hispanic, or from other racial/ethnic groups; who entered prenatal care after the first trimester; and whose pregnancies were unintended were less aware of folic acid. This study indicates that gaps persist among women in low socioeconomic groups. Overall, PRAMS data indicated an increase in folic acid awareness among women with recent deliveries. However, this awareness might be too late for the pregnancy that has occurred, indicating a continued need to educate all reproductive-aged women regarding the need to take folic acid before they become pregnant.
