RESUMO
OBJECTIVE: To determine whether exclusive breastfeeding is associated with readmission of jaundiced newborns. METHODS: We retrieved medical records of 51 consecutive neonates >35 weeks with jaundice who were readmitted to the hospital, and compared to 164 controls. Data on gender, gestational age, birth weight, mode of delivery, feeding, bilirubin levels and breastfeeding counseling were analyzed. RESULTS: 24% babies were readmitted for hyperbilirubinemia reaching phototherapy level. Early term infants had significantly higher risk for readmission compared to term [OR (95% CI) 2.12 (0.99-4.53); P= 0.05]. The risk of readmission was lower amongst subjects receiving mixed/formula feeding [OR (95% CI) 0.51 (0.26-0.98); P=0.046] odds of readmission decreased for those feeding >8 times per day (OR (95% CI) 0.46 (0.23-0.91); P=0.016], and those who stayed in hospital for more than 2 days after birth [OR (95% CI) 0.95(0.93-0.97); P<0.001]. CONCLUSION: Ensuring feeding at least 8 times per day and keeping newborns beyond the first 24 hours decreases the chance of readmission.
