Awareness of Periconceptional Folic Acid in Parents of Children Affected by Spina Bifida - A Pilot Study

Abstract

Background: Spina bifida is a congenital malformation involving an open vertebral column resulting from failure in neural tube closure. It is among the most frequently occurring birth defects, observed in 1-3 cases per 1,000 live births worldwide. Conventionally requiring surgical repair, it can cause severe neurologic and musculoskeletal complications. However, consumption of prophylactic folic acid in mothers, at least 3 months before to 12 weeks after conception (periconceptional) has been shown to reduce the incidence of spina bifida by approximately 75%. This makes ascertaining parental understanding of such benefits critical. Therefore, this study provides baseline information on the awareness of periconceptional folic acid among parents whose children previously underwent surgical repair of spina bifida defects.

Materials and methods: The study subjects constituted 80 parents whose biological children had undergone surgical repair of spina bifida defects from 2014 to 2021 at a large paediatric tertiary care centre in South India. Upon providing informed consent, the subjects answered a cross-sectional telephonic survey containing 21 questions aimed at exposing their understanding of folic acid and its association with spina bifida.

Results: None of the mothers had consumed folic acid before conception. However, 75% of them had consumed it as prescribed by their obstetrician during the first trimester of pregnancy. Finally, only 35% of them were aware of its role in preventing spina bifida.

Conclusion: The awareness of periconceptional folic acid and its preventive role in spina bifida was low amongst parents whose children were once treated for same congenital abnormality.
