ABSTRACT
Growth hormone levels were measured in 33 umbilical cord blood samples collected from babies born at JIPMER Hospital during April and May-1998. The study was done to evaluate the growth hormone profile in relation to birth weight and gestational age. There was statistically significant difference in the cord blood growth hormone levels between babies weighing > 2500 gms (28.1 +/- 12.83 ng/dl) and low birth weight babies (76.8 +/- 55.7 ng/dl). The difference in growth hormone levels between term babies weighing > 2500 gms and preterm babies (72.5 +/- 29.4 ng/dl) was also statistically significant. However, there was no significant difference in the cord blood growth hormone levels between term low birth weight and preterm babies. Growth hormone levels were higher in preterm babies and low birth weight babies as compared to term babies weighing > 2500 gms indicating that growth hormone has an important role to play in intrauterine growth along with other growth promoting factors.
