Insulin-like growth factor-1 and growth in infants 0-6 months of age

Background During infancy, growth is affected by many factors, including hormones. Insulin-like factor-1 (IGF-1) a hormone with an important role in regulating somatic and organ development.
 Objective To analyze for possible correlations between IGF-1 levels infant from 0-6 months of age.
 Methods A prospective study was conducted on 38 infants birth to 6 age. Inclusion criteria were full-term newborns normal weight singleton birth. Serum measured twice, umbilical cord blood at Anthropometric measurements made every three months. Paired T-test used mean among time points, Pearson’s correlation test growth.
 Results Mean level decreased age (89.6 ng/mL vs. 48.3 ng/mL, respectively; P<0.001). Delta had positive significant delta 3 (r=0.347; P=0.033) (r=0.386; P=0.017), as well head circumference (r= 0.356; P=0.028) (r=0.357; P=0.028). However, there negative body −0.459; P=0.004) length −0.414; P=0.010).
 Conclusions. There iss decrease the first life. Umbilical has increment
