Abstract
BackgroundNeonates with intrauterine growth restriction (IUGR) have a high lipid profile that predisposes them to cardiovascular disease later in life. We aimed to evaluate the effect of omega 3 supplementation on serum leptin level, lipid profile, and growth in neonates with IUGR.MethodsThis clinical trial was conducted on 70 full-term neonates with IUGR. Neonates were randomly divided into two equal groups; the treatment group: received omega 3 supplement (40 mg/kg/day) for 2 weeks after the establishment of full feeding, and the control group, who were followed up to full feeding without any supplementation. Serum leptin level, total cholesterol (TC), high-density lipoprotein (HDL), triglycerides (TG), low-density lipoprotein (LDL), and anthropometric measurement were evaluated at admission and after 2 weeks of omega 3 supplementation in both groups.ResultsAfter treatment, HDL significantly increased, unlike TC, TG, LDL, LDL, and serum leptin levels, which significantly decreased in the treatment group compared to the control group after treatment. Interestingly, weight, length, and ponderal index greatly increased in omega 3-treated neonates compared to the control group.ConclusionOmega 3 supplementations lowered serum leptin level, TG, TC, LDL, and VLDL but increased HDL and growth in neonates with IUGR.Clinical trial registrationThe study was registered at clinicaltrials.gov (NCT05242107).ImpactNeonates with intrauterine growth retardation (IUGR) were reported to have a high lipid profile that predisposes them to cardiovascular disease later in life. Leptin is a hormone that adjusts dietary intake and body mass and has a significant role in fetal development. Omega 3 is known to be essential for neonatal growth and brain development.We aimed to evaluate the effect of omega 3 supplementation on serum leptin level, lipid profile, and growth in neonates with IUGR.We found that omega 3 supplementations lowered serum leptin level and serum lipid profile but increased high density lipoprotein and growth in neonates with IUGR.
