Feeding patterns of Brazilian preterm infants during the first 6 months of life, Londrina, Parana, Brazil

The present study evaluated the breastfeeding practice of 278 preterm infants born at the University Hospital of Londrina, Parana, Brazil, during hospitalization and in the first 6 months of life. Data were obtained from the hospital records, and the mothers were interviewed by home visit (75.5%) or by telephone (24.5%) when the children were 6 months old. Data were analyzed statistically using the Kaplan-Meier survival method and Cox's multivariate regression model. During hospitalization, 100% of the preterm infants received human milk and 31% received exclusive breastfeeding. The median duration of exclusive breastfeeding and breastfeeding was 63.5 and > 180 days, respectively. The prevalence of breastfeeding in the sixth month was 54.7%, and 6.8% of the infants were still exclusively breastfed. Pacifiers were used (currently using or ever used) by 127 (45.7%) preterm infants and were associated with a 1.67 times higher risk of interruption of exclusive breastfeeding.
