Factors associated with folic acid deficiency in pregnant women and its repercussions in the newborn: a cross-sectional study

This study estimated the prevalence and identified factors associated with folic acid deficiency among pregnant women receiving care at a maternal-child referral hospital in northeastern Brazil and its repercussions on the newborn. Folic acid deficiency was associated with lack of supplementation, absence of a partner, and assessment during the second trimester. No neonatal repercussions were observed. The findings of this study reinforce the importance of timely prenatal care and adequate supplementation.
