[Incidence and duration of breast-feeding by type of delivery: a longitudinal study in southeastern of Brazil].
OBJECTIVE
To compare the incidence of breastfeeding according to type of delivery.


METHODS
Population-based cohort study of 655 children born in 1993 and followed up during the first three months of life through home visits.


RESULTS
Breastfeeding duration was similar among babies born either by vaginal delivery or by emergency cesarean section. Babies born by elective cesarean section, however, presented a three times higher risk of stopping breastfeeding in the first month of life, after adjusting for possible confounding factors (odds ratio = 3.09; 95% CI 1.3-7.2). The increased risk did not persist into the third month of life.


CONCLUSIONS
It is recommended that health services pay special attention, in the promotion of breastfeeding, to babies born by elective cesarean section, as a way to avoid early weaning.
