Recent research we have done at Mekelle University soon to be published has confirmed that there is a high rate of neural tube defects affecting the brain and spinal cord in Tigray. Experience suggests this is also the case in other parts of Ethiopia as well. At least 131 out of every 10,000 births is affected with some areas having almost twice that number. Defects result in death at birth for about 77% of the pregnancies affected, usually with anencephaly, while the 23% born alive usually have severe paralysis of the lower extremities and often need a operations to close the open spine, closure of myelomeningocoel, and to control pressure in the brain, ventricular peritoneal shunt, for lumbar and thoracic myelomeningocoel associated with an Arnold Chiari II malformation causing hydrocephalus. Lesser numbers of encephalocoel often requiring closure were encountered as well.
The most likely significant cause is lack of diversity in the diet and especially failing to consume foods with the vitamin folic acid. This is usually found in green and leafy vegetables as well as fresh fruits. Cooking foods such as chick peas which may contain folic acid will destroy much of it.
Around the world these birth defects have been reduced about 75% by encouraging women to plan their pregnancy and take 4 milligrams of folic acid daily starting before conception. We are working with our research group at Mekelle University to help the Tigray Regional Health Bureau and the Ethiopian Ministry of Health come up with programs to reduce these defects but this will take time.
In the meantime we encourage all women in Ethiopia to plan their pregnancy, starting folic acid supplementation before they conceive, and practice dietary diversity. They should try to wait one year between pregnancies, and understand that breast feeding increases their need for folic acid. Very young and older women are more susceptible to having children with these defects. Other factors may be involved besides folic acid deficiency but the good news is that folic acid supplementation will likely still reduce these defects.
