title: [Effects of feeding patterns after hospital discharge on increase rates of growth indices in preterm and low-birth-weight infants within 3 months after birth].
abstract: OBJECTIVE
  To study the effects of post-discharge formula (PDF) for preterm infants, breast milk (BM) and term infant formula (TF) on increase rates of body weight, length and head circumference in preterm and low-birth-weight infants (PLBWIs) from discharge to 3 months after birth, and to provide a reference for the choice of feeding pattern for PLBWIs.
  
  
  METHODS
  A total of 407 PLBWIs discharged from the newborn departments of ten hospitals in Guangzhou City and Foshan City in Guangdong Province, China were chosen for this study. According to feeding pattern, they were assigned to three groups: PDF-fed (n=258), BM-fed (n=58) and TF-fed (n=91). Their body weight, length and head circumference were measured at 3 months after birth, and the increase rates of growth indices relative to baseline values (at birth) were calculated and compared.
  
  
  RESULTS
  At 3 months after birth, the PDF-fed group had significantly greater body weight, length and head circumference than the BM-fed and TF-fed groups (P<0.05). The increase rates of body weight and length were significantly higher in the PDF-fed group than in the BM-fed and TF-fed groups (P<0.05).
  
  
  CONCLUSIONS
  Compared with those fed with BM and TF after discharge, the PDF-fed PLBWIs have higher increase rates of body weight and length and show greater body weight and length at 3 months after birth. However, further study is needed to investigate the long-term effects.
