Background:
The Baby-Friendly Hospital Initiative began promoting exclusive breast-feeding in 2001 in Taiwan; however, few studies have investigated its impact. This study evaluated the influence of breast-feeding on Taiwanese neonates with regard to the frequency of jaundice, body weight loss (BWL), and elimination of both urine and stool.
Methods:
The medical records of 313 healthy mother-neonate pairs admitted at our hospital were reviewed retrospectively and divided into three groups: exclusively breast-feeding (n=161), mixed (breast/formula) feeding (n=80), and exclusively formula feeding (n=72).
Results:
Compared with the exclusively formula feeding group, in the exclusively breast-fed neonates, the average total serum bilirubin level at 3 days after birth (p < 0.001) and the rate of significant hyperbilirubinemia ≥ 15 mg/dL (p<0.05) were significantly higher; the average BWLs at 2 and 3 days after birth (p < 0.001, p < 0.001) and the rate of BWL ≥ 10% (p < 0.05) were significantly higher; the average frequency of stool passage at 2 and 3 days after birth (p < 0.001, p < 0.001) and urination at 1, 2, and 3 days after birth (p < 0.001, p < 0.001, p < 0.001) were significantly less. The factors associated with a mother's choice of infant feeding type include maternal age and delivery method.
Conclusion:
Breast-feeding during the initial days of life has a significant influence on the degree of jaundice, amount of BWL, and the frequency of stool passage and urination.
