[Relationship between early serum lipid profiles and respiratory distress syndrome in preterm infants].

Objective: To investigate early serum lipid profiles in preterm infants and their relationship with neonatal respiratory distress syndrome (RDS).

Methods: Appropriate-for-gestational-age (AGA) preterm infants were grouped according to gestational age (GA) or birth weight (BW). AGA full-term infants were randomly selected as the control group.
