title: Cord insulin and C-peptide--distribution in an unselected population.
abstract: OBJECTIVE
  To assess the distribution of cord blood insulin in an unselected population, and examine its relation to birthweight centiles.
  
  
  METHODS
  District General Hospital in Nottinghamshire.
  
  
  METHODS
  209 unselected singleton births.
  
  
  METHODS
  Cord blood insulin; cord blood C-peptide; birthweight centiles.
  
  
  RESULTS
  Hyperinsulinaemic babies (greater than 97th centile for cord insulin) were found at all birthweight centiles. 15% of high birthweight babies were hyperinsulinaemic. For low birthweight babies, the distribution of cord insulin/C-peptide was skewed indicating a high number of low values. Hypoinsulinaemic babies were present up to the 50th centile for birthweight.
  
  
  CONCLUSIONS
  Abnormalities of fetal insulinisation may be found in babies of all birthweights.
