Observational study of maternal anthropometry and fetal insulin

By H. Soltani, C. Bruce and R. B. Fraser


Aims- To examine the relation between maternal body fat and fetal metabolism.<p></p>Methods- In this observational study, cord blood samples were collected from 60 infants of healthy women for the measurement of insulin and C peptide concentrations. Maternal weight, height, body mass index (BMI) and body composition (skin-fold thickness measurements and bioelectrical impedance) were assessed at 13-15 weeks of gestation. Twenty five of the volunteers agreed to have a 75g oral glucose tolerance test at 28-31 weeks of gestation.<p></p>Results- Positive correlations were observed with both cord insulin or C peptide concentrations and maternal early pregnancy BMI (r=0.44, p=0.002 and r=0.33, p=0.008, respectively). There was no significant correlation between cord insulin or C peptide concentrations and birthweight or birth weight centiles.<p></p>Conclusion- Maternal BMI could be a predictor of fetal cord insulin concentration
