Abstract
Glucagon-like peptide 1 (GLP-1) is a gut-derived peptide with insulin-like effects.
Our aim was to analyze cord blood GLP-1 levels of macrosomic and appropriate-gestational-age
(AGA) neonates from non-diabetic mothers. A case-control study was conducted with
22 term macrosomic neonates (birth weight≥4000 g) and 22 AGA (birth weight>10th percentile and<4000 g) pregnancies. Cord blood GLP-1 levels of neonates were measured.
There were no significant differences in maternal age, gestational age and gravida
between the 2 groups. Umbilical cord blood GLP-1 levels were significantly lower in
macrosomic neonates (6.9±2.9 pg/mL) compared with control group (10.3±3.7 pg/mL) (p=0.002).
Binary logistic regression analysis showed only the maternal BMI to be an independent
statistically significant predictor of macrosomia (odds ratio=2.459; 95% CI, 1.170–5.170;
P=0.018). The results of our study revealed decreased GLP-1 levels in macrosomic neonates,
and maternal BMI was an independent predictor of macrosomia.
