| Abstract: | OBJECTIVE: To assess the distribution of cord blood insulin in an unselected population, and examine its relation to birthweight centiles. SETTING: District General Hospital in Nottinghamshire. SUBJECTS: 209 unselected singleton births. MEAN OUTCOME MEASURE: 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. |
