title: Comparison of enteral feeding of preterm infants between two hospitals in China and United States.
abstract: OBJECTIVE
  To compare the details of preterm infants enteral feeding between the two hospitals in China and in the United States, and to analyze the reason of the differences.
  
  
  METHODS
  A retrospective cohort study was conducted. Infants < 32 weeks were enrolled from Cincinnati University Hospital (CUH) during January 2011 to January 2012 and Peking Union Medical College Hospital (PUMCH) during January 2011 to May 2012. Basic data and enteral feeding data of the two groups were compared.
  
  
  RESULTS
  Eighty-two infants in CUH group and 74 infants in PUMCH group were enrolled, infants in CUH group were much smaller than PUMCH group (gestational age (29.1 ± 2.0) versus (30.6 ± 1.3) weeks, p = 0.000, birth weight (1204 ± 328) versus (1406 ± 320) g, p = 0.000). Significantly more infants in CUH group received human milk as the first enteral feeding (78/82 versus 7/74, p = 0.000). Human milk feeding rate in first 28 days in CUH group was much higher (77/82 versus 7/74, p = 0.000). The initial milk volume, and the milk volume on the 7th, 14th, 21st and 27th day of CUH group were significant larger [(15.9 versus 9.3 ml/kg·d, p = 0.000), (79.8 versus 35.2 ml/kg·d, p = 0.000), (133.2 versus 76.4 ml/kg·d, p = 0.000), (140.6 versus 108.6 ml/kg·d, p = 0.000), (142.2 versus 121.5 ml/kg·d, p = 0.002)]. CUH group achieved full enteral feeding sooner (12.0 versus 22.4 d, p = 0.000).
  
  
  CONCLUSIONS
  Preterm infants achieved full enteral feeding sooner at CUH compared to PUMCH. Human milk feeding may improve enteral feeding tolerance. We need more aggressive enteral feeding proposal in PUMCH.
