Folic acid deficiency during pregnancy is most closely linked to which condition?

• A. Neural tube defects
• B. Iron-deficiency anemia
• C. Gestational diabetes
• D. Hypertensive disorders

Answer: (A)

Folic acid is essential for DNA synthesis and rapid cell division, especially in early pregnancy when the neural tube is forming. The neural tube normally closes within the first few weeks of gestation; adequate folate around this time helps ensure proper closure. When folate stores are insufficient, the neural tube may fail to close, leading to neural tube defects such as anencephaly or spina bifida. That direct link to proper neural tube closure is why folic acid deficiency during pregnancy is most closely associated with neural tube defects. Iron-deficiency anemia, gestational diabetes, and hypertensive disorders have other underlying causes and are not primarily tied to folate status. Ensuring adequate folate intake before conception and in early pregnancy helps prevent these neural tube defects.
