INTRODUCTION : Breast changes can have a significant impact on breastfeeding success. In Brazil the prevalence of breast surgery is higher among the population of private health system users. Another risk factor that can interfere in successful breastfeeding in these patients is the high rate of cesarean birth, which in turn may be associated with nipple trauma.OBJECTIVES : The aim of this study was to evaluate the influence of breast surgery and other breast changes on breastfeeding success in patients undergoing elective cesarean section at a private hospital.METHODS : We included in the study newborns undergoing elective cesarean section equal to or greater than 37 weeks' gestation. Data were obtained from hospital records, interviews with the mothers during their stay in the maternity ward and via telephone at the end of the second week and three months after delivery. The variables were gestational age, presence of partners, number of pregnancies, type of nipple, previous breastfeeding, pain during breastfeeding, complementary prescription, silicone breast implants, breast reduction surgery, and bleeding nipples fissures. A logistic regression model was adjusted considering exclusive breastfeeding response at three months as a variable and as dependent variables those significant at the 30% level in previous analysis.RESULTS : The study sample consisted of 1117 newborns and their mothers whose deliveries occurred consecutively and met the inclusion criteria. Of the 1117 mothers, 741 (66.34%) had exclusive breastfeeding at three months of life. All the variables studied represented significant risk factors for the lack of exclusive breastfeeding at three months, except pain during breastfeeding and presence of cracks. In multivariate analysis, the variables that remained significant after adjusting for confounding factors were use of food supplements in the first 24 hours of life (odds ratio [OR] 2.11, confidence interval [CI] 1.62 95% 2.75); flat nipple (OR 2.40, 95% CI 1.58 to 3.65); silicone breast implant (OR 1.88, 95% CI 1.24 to 2.85); and breast reduction surgery (OR 5.65, 95% CI 2.92 to 10.85).CONCLUSIONS : In this population of patients undergoing elective cesarean section in a private health service, breast surgeries, especially breast reduction, were important risk factors for the absence of exclusive breastfeeding at three months postpartum. Another important risk factor for early weaning was the type of flat nipples.
