Few
things can cast a more frightening shadow over the joy of
childbirth than finding out that your child is afflicted with
a birth defect such as anencephaly or spina bifida. Babies
with anencephaly never develop a brain and are stillborn or
die shortly after birth; those afflicted with spina bifida
have a defect in the spinal column that can lead to paralysis
and/or mental retardation.
Evidence suggests that folic acid can help prevent these
two major birth defects, and a recent study in The New
England Journal of Medicine echoes this hypothesis. As
part of a public health campaign conducted in China, birth
defects were evaluated among the fetuses or infants of women
who took folic acid (at any time before or during pregnancy)
compared with those whose mothers did not take folic acid.
Results supported the protective effect of folic acid:
€ Folic acid supplementation: 0.8 defects per 1,000 pregnancies;
€ No folic acid supplementation: 2.9 defects per 1,000
pregnancies.
These results are especially important because, as the authors
note, the baseline rate of defects in the southern region
of China is similar to rates in the United States and other
countries. If you're expecting the birth of a child, consult
with your team of health care professionals on a comprehensive
exercise and nutrition program that can help ensure a healthy,
happy newborn.
