Preterm infants treated with soy and olive oil based parenteral lipid solutions (Intralipid and Clinoleic) have low levels of LCPUFAs and increased supply of DHA has been recommended. It has been demonstrated that low DHA levels are associated with compromised fetal insulin sensitivity and insulin resistance in preterm infants is common and strongly associated with neonatal morbidity. Few studies have examined associations between low AA and preterm neonatal morbidities.
