A Comparison of Factors Associated with Cessation of Exclusive Breastfeeding at 3 and 6 Months.

AIM: To analyze the association of labor and sociodemographic factors with cessation of exclusive breastfeeding (EBF) at 3 and 6 months of life. MATERIALS AND METHODS: A prospective cohort study (n = 529) was performed in a tertiary hospital with the Baby-Friendly Hospital Initiative (BFHI) award. Labor and sociodemographic factors were investigated. Single-term newborns were included. After 3 and 6 months, telephone calls were made to determine the type of lactation. Univariate analysis was performed with the chi-square test or Fisher's exact test. Multivariable logistic regression models were developed to determine risk factors associated with cessation of breastfeeding at 3 and 6 months. RESULTS: At 3 months, 523 participants (98.9%) were contacted, of whom 64.4% maintained EBF. Factors associated with cessation were pacifier use (odds ratio [OR] 3.49; 95% confidence interval [95% CI] 2.24-5.43), cesarean delivery (OR 4.49; 95% CI 2.96-6.83), no college degree (OR 2.01; 95% CI 1.35-3.01), and not attending breastfeeding support groups (OR 1.96; 95% CI 1.22-3.12). At 6 months, 512 participants (96.8%) were contacted, of whom 31.4% maintained EBF. Factors associated with cessation were reintegration into the workplace (OR 4.49; 95% CI 2.96-6.83), pacifier use (OR 3.49; 95% CI 2.24-5.43), and primiparity (OR 1.61; 95% CI 1.05-2.46). CONCLUSIONS: Several risk factors are associated with the premature cessation of EBF. There is a need to define strategies to correct modifiable factors and to promote protective factors with the aim of improving the success rate of EBF to reach the recommendations of the World Health Organization.

The Relationship of the Administration of Intrapartum Synthetic Oxytocin and Breastfeeding Initiation and Duration Rates.

AIM: The consequences that intrapartum administration of hormones can have on breastfeeding are unclear. The aim of the study is to determine if synthetic intrapartum oxytocin, used routinely for induction/stimulation, has a relationship to initiation/duration of breastfeeding. PATIENTS AND METHODS: We conducted a cohort study that was carried out in a tertiary university hospital distinguished by WHO-UNICEF as a BFHI (Baby-Friendly Hospital Initiative). A group of 53 mother and newborn dyads who had been exposed to intrapartum synthetic oxytocin were compared with 45 nonexposed dyads. A breastfeeding questionnaire was administered by a midwife blind to patient group through phone calls 3 and 6 months after delivery. RESULTS: No statistically significant differences were observed between the two groups in the rates of mothers exclusively breastfeeding (EBF) or nonexclusively breastfeeding. The percentage of those who were EBF when discharged was 97.3% in the oxytocin-nonexposed group and 87.1% in the oxytocin-exposed group (p = 0.14). At 3 months, the group rates of exclusive breastfeeding were 72.5% in the nonoxytocin-exposed group versus 65.9% in the oxytocin-exposed group (p = 0.71). At 6 months, rates of breastfeeding were 31.4% versus 27.9% (p = 0.53) in the oxytocin-nonexposed and oxytocin-exposed groups, respectively. CONCLUSIONS: In this study, no statistically significant effect of intrapartum synthetic oxytocin administration was observed pertaining to the initiation or duration of breastfeeding.
