Folic Acid & Neural Tube Defects: Data & Statistics

  • In the United States, 3,000 pregnancies are affected by neural tube defects every year (1).
  • Hispanic women have higher rates of neural tube defects than non-Hispanic women in the United States (2).
  • Worldwide, there are more than 300,000 babies born with neural tube defects each year (3).
  • The total lifetime direct cost of care for a child born with spina bifida in the United States is estimated to be $791,900 (4).
  • Increasing folic acid intake among women of childbearing age can help prevent 150,000-210,000 of the more than 300,000 neural tube defects that occur each year in low- and middle-resource countries (5).

Key Findings: Assessing the Association between Natural Food Folate Intake and Blood Folate Concentrations
The journal Nutrients has published a new study that assessed the relationship between the amount of natural food folate consumed by women and their blood folate concentrations.

Key Findings: Population Red Blood Cell Folate Concentrations for the Prevention of Neural Tube Defects
This study describes the relationship between women’s blood folate concentrations and the risk of having a baby affected by a neural tube defect.
