To study the role of various hormones in the control of fetal leptin secretion during labour, 33 pregnant women with normal singleton term pregnancy were recruited. At the time of spontaneous vaginal delivery, a venous blood sample was taken from the women together with a venous and an arterial cord blood sample. In all blood samples, leptin, cortisol, prolactin and progesterone were measured. Serum leptin and cortisol values were significantly higher, while those of prolactin and progesterone were significantly lower in the mother than in the two umbilical vessels (p < 0.01). Cortisol levels were significantly higher in the umbilical artery than in the umbilical vein (p < 0.01). Serum leptin values in the umbilical artery and vein correlated significantly with the corresponding values of cortisol (r = 0.523 and r = 0.580 respectively, p < 0.01), but not with those of prolactin and progesterone. A weak but significant correlation was found between leptin values in the two umbilical vessels and birth weight (r = 0.385 and r = 0.401 respectively, p < 0.05). In multiple regression analysis, cortisol values but not birth weight was the most important determinant of leptin values. Birth weight, however, correlated significantly with placental weight (r = 0.776, p < 0.001). These results demonstrate for the first time that leptin concentrations in the umbilical vessels at normal vaginal delivery correlate significantly with cortisol values, thus providing evidence that cortisol mediates a labour stimulating effect on fetal leptin secretion. It is suggested that cord blood leptin values at delivery are not a good predictor of neonatal weight.
