LEP and fetal growth restriction: Omega 3 fatty acids may also play a role in determining the length of gestation and in preventing perinatal depression.43 Additionally, based on our findings, we can theorize that omega 3 could be safe in IUGR neonates for controlling the serum leptin level and lipid profile; therefore, screening them is important to be done in all IUGR neonates at birth and during follow-up.
