Background: The nutrition and immunity effects of breastfeeding have been known, so it seems important to identify effects of different factors on secretion of breast milk for encouraging the mothers to breastfeeding.
Materials and methods: In this analytic prospective study, the effects of different types of delivery on continuity of breastfeeding and better weight gain of newborns were evaluated in 200 newborns by normal vaginal delivery and 200 newborns by cesarean section, in 1383 at three hospitals in Tehran. The newborns weight in 1.5- and 3-month and the type of newborns nutrition were compared between two groups.
Results: Among vaginal delivery group, breast feeding was associated with full success in 70%, partial success in 21.5% and no success in 8.5%, while these figures were 48%, 29% and 23% in cesarean group, respectively.
Conclusion: It seems to be longer time of breast feeding and better weight gain of infants in normal vaginal delivery comparing to cesarean section.
