Abstract
The present study was based on 6940 live singleton births without obvious congenital abnormalities delivered at 2432 weeks. The birthweight of children born by Caesarean section was lower than that of those born vaginally. This applied whether the baby survived or died during the neonatal period; whether or not there was maternal hypertensive disease; and whether the delivery was at 2428 or 2932 weeks. Birthweight for gestational age was greater in those born by emergency Caesarean than those born by elective Caesarean section. After consideration of a number of potential confounding factors, these findings accord with the hypothesis that the baby might gain weight during labour.
Key words: birthweight/Caesarean section/weight gain
