Methodology
NCBDDD is collaborating with states in NBDPN to systematically collect population-based birth defects data on neural tube defects in a timely manner. Nine state birth defects surveillance programs that can collect anencephaly cases for all pregnancy outcomes were included in the dataset. Anencephaly cases are identified using either ICD-9 (741.0, 741.9) or CDC/BPA (741.00 – 741.99) codes.
Interventions
The USPSTF recommends that all women planning or capable of pregnancy take a daily supplement containing 0.4 to 0.8 mg (400 to 800 µg) of folic acid.
Fortifying food products with folic acid is an effective way to help prevent major birth defects of the brain and spine.
If a woman has enough folic acid in her body before she is pregnant, it can help prevent major birth defects of her baby’s brain and spine. Community campaigns encourage more women to use folic acid supplements.
