comparison of the blood level of leptin in umbilical cord of newborns of mothers with gestational diabetes and normal mothers and its relationship with growth indices of newborns

conclusions changes in neonatal leptin levels can reflect changes in the body fat tissue and neonatal birth weight and could be effective in predicting weight gain in newborns with mothers who have gestational diabetes and may reduce birth trauma or future complications. results serum leptin levels in the cord blood of mothers with gdm were significantly higher than in normal mothers. there was a significant relationship between serum leptin levels and birth weight in infants with diabetic mothers. in this study, no significant correlation was observed between cord leptin levels and other growth indices. materials and methods after delivery and using the aseptic method, 5 ml of blood from the umbilical vein was taken immediately by staffs to separate serum and was then stored at −20°c. serum level of leptin was measured using the elisa method in two groups: “case” and “control.” all information collected in the questionnaires was analyzed using spss-19 software as well as other statistical methods. objectives due to the lack of similar studies in ahvaz, we aimed to determine the relationship between umbilical blood levels of this hormone with growth indices of newborns with normal mothers and mothers with gestational diabetes mellitus (gdm). background diabetes is defined as an abnormal increase in blood glucose levels and is the most common disease that can complicate pregnancy. leptin, a hormone produced mainly in adipose tissue, plays an important role in preventing fat accumulation in tissues such as skeletal muscle and myocardium and can be used to evaluate changes in lipid levels effectively. leptin cannot cross the placental barrier, and its level in the umbilical cord is of fetal origin.
