title: Epidemiological survey on newborns born at the obstetric departments in hospitals in mid-southern region of China in 2005.
abstract: OBJECTIVE
  To investigate the situations at birth of newborns in the mid-southern region of China by performing a survey on the newborns born at urban hospitals.
  
  
  METHODS
  A total of 23 hospitals in the mid-southern region of China were selected to participate in this survey. The data of 15,582 newborns who were born at the obstetric departments from January 1, 2005 to December 31, 2005 were retrospectively investigated.
  
  
  RESULTS
  The male to female ratio among newborns was 1.16:1. The incidence of preterm birth was 8.11%, while very low birth weight (VLBW) infants accounted for 0.73%. The rates of spontaneous vaginal delivery and cesarean section ware 57.52% and 40.82%, respectively, while the other delivery modes accounted for 1.66%. The incidence of neonatal asphyxia was 3.78% (0.75% for heavy asphyxia). The mortality of newborns was 0.55% (5.56% for preterm infants).
  
  
  CONCLUSIONS
  The incidences of preterm birth and neonatal asphyxia are relatively high in the mid-southern region of China. The rate of cesarean section is abnormally high, which is due mainly to social factors.
