Abstract
The impact of cup-feeding or bottle-feeding on weight gain, oxygen saturation, and breastfeeding rates of preterm infantswas studied in 34 bottle-fed and 44 cup-fed preterm infants. At initiation of oral feeding, postconceptional age and weight were 37.2 ± 2.2 weeks and 1676 ± 83 g for the bottle-fed group (BF) and 37.0 ± 1.6 weeks and 1637 ± 40 g for the cup-fed (CF) group, respectively. No significant differences between groups were found with regard to time spent feeding, feeding problems, weight gain, or breastfeeding prevalence at discharge or at 3-month follow-up. Possible beneficial effects of cup-feeding were lower incidence of desaturation episodes (13.6% vs 35.3%, CF vs BF, P= .024) and a higher prevalence of breastfeeding at 3 months among those still breastfeeding at the first follow-up visit (68.4% vs 33.3%, CF vs BF, P= .04).
