Conclusion
We found that neonates in utero exposed to BDZs had a statistically significant lower gestational age of -3.2 days compared to neonates not exposed to BDZs in mothers with mental disorders. This difference seems not clinically relevant. We also found that the use of BDZs during pregnancy is associated with prolonged psychiatric care after delivery concerning the mother. We found no differences between exposed or none exposed to BDZs regarding birth weight, the number of congenital malformations, APGAR score, and the need for prolonged psychiatric care.
