The petitioners contend that increased consumption of folic acid will reduce the risk of births with neural tube defects among this group.
While some of the studies were randomized trials, you can no longer conduct a true randomized design and withhold folic acid from women; it's simply not ethical knowing what we know about the preventive benefits of folic acid for neural tube defects.
But it has been shown that women who have had a previous child with a neural tube defect, a high-risk group, need 5 mg/day to have an impact on prevention (Lancet 1991;338:131-7).

Furthermore, it appears women with diabetes and poor glucose level management, women of Hispanic descent, non-Hispanic African American women, obese women, those with a prior history of pregnancies affected by neural tube defects, and women who take antiepileptic drugs are at higher risk of developing neural tube defects (Wilson et al.
Although low levels of maternal folic acid--a B vitamin found in green leafy vegetables--is an established risk factor for neural tube defects, (5) little is known about other environmental factors that may contribute to these birth defects.
Conclusion: Neural tube defect is identified as major congenital abnormality in this community and consangious relationship being the biggest risk factor associated with it.

Neural tube defects are severe abnormalities of the central nervous system that develop in babies during the first few weeks of pregnancy resulting in malformations of the spine, skull, and brain, which may lead to seizures, intellectual disability, or sight problems, paralysis and a variety of urological and neurological complications.
