ABSTRACT


Background 

Awareness among women about folic acid supplementation during pregnancy showed an increment. Therefore, a difference in the prevalence of Neural Tube Defects happened.

Objectives

The aim of this study was to identify the prevalence of NTDs in Sulaimani governorate and to make a comparison between the 2 periods before and after folic acid fortification of wheat in Iraq and with improved awareness of mothers.

Methods

This observational study was conducted in Sulaimani Maternity Teaching Hospital in two different periods. The first period extending from 1/7/2005 to 31/12/2006, out of 19831 live births, records of neonates with anencephaly, meningocele, meningomyelocele and encephalocele were reviewed. The second period extending from 1/7/2012 to 31/12/2013, out of 26841 live births, a combined record revision and direct interview of mothers who had delivered a newborn with Neural Tube Defects was followed.

Results

Results showed that during the first period of study, out of 19831 Live Births, 52 cases of Neural Tube Defects were encountered making a prevalence rate of 2.6/1000 Live Births. The total number of deliveries during the second period was 26841 Live Births and the number of newborns having Neural Tube Defects was 31, making
a prevalence rate of 1.16/1000 Live Births.

Conclusion

It was found that Neural Tube Defects are common in our area and that fortification of wheat flour with folic acid together with providing folic acid to pregnant mothers at the antenatal clinics had an overall effect in decreasing the prevalence of this defect.
