Objective To compare the feeding pattern of preterm infants between two hospitals in China and the United States. Methods A retrospective cohort study was conducted. Infants < 32 weeks were enrolled from Cincinnati Children's Hospital Center Cincinnati University Hospital (CCHMC group) between January 2011 and January 2012 and Peking Union Medical College Hospital (PUMCH group) between January 2011 and May 2012. Enteral and parenteral feeding data of the two groups was compared. Results Eighty-two infants in the CCHMC group and 74 infants in the PUMCH group were enrolled. The gestational age and birth weight of infants in the CCHMC group were smaller than the PUMCH group (P<0.01). The total dosage of amino acid (58±30 g/kg vs 24.0(19.6, 32.8) g/kg; P<0.01) and fat [35±16 g/kg vs 14.0(11.0, 22.5) g/kg; P<0.01], in the PUMCH group were higher than the CCHMC group. The duration of parenteral nutrition in the PUMCH group was longer than the CCHMC group[(24±10 d vs 8.0(6.0, 11.0) d; P<0.01]. The breast feeding rate in the CCHMC group was higher (94% vs 10%; P<0.01) than in the PUMCH group. The time for achieving full enteral feeding in the CCHMC group was shorter [12.0(10.0, 14.0) d vs 22.4±9.3 d, P<0.01] than in the PUMCH group. The incidences of necrotizing enterocolitis (13% vs 3%; P<0.05) and sepsis (32% vs 12%; P<0.01) in the CCHMC group were higher than in the PUMCH group. Conclusions Preterm infants in the PUMCH group have a prolonged duration of parenteral nutrition and an increased incidence of sepsis compared to the CCHMC group. Fortified human milk feeding and more aggressive enteral feeding proposal in PUMCH is recommended.
