title: [Perinatal mortality: extent and causes in Lubumbashi, Democratic Republic of Congo].
abstract: BACKGROUND
  The present study was initiated in order to determine the rate, the causes and the risk factors for perinatal mortality in Lubumbashi, Democratic Republic of Congo.
  
  
  METHODS
  Data for this cross-sectional study were collected by interviewing participating women and by analysis of medical files. Women who gave birth in 2010 and were residents of Lubumbashi during the same year were included.Women were included irrespective of the pregnancy outcome and perinatal survival was determined for newborns aged at least seven days.Women were recruited from households selected by cluster sampling for healthcare zones. Perinatal mortality was defined as stillbirths and early neonatal deaths per 1000 births. Risk factors were sought using the odds ratio method adjusted by logistic regression using a 5% threshold.
  
  
  RESULTS
  Among 11,536 surveyed women, there were 11,633 births including 177 stillbirths and 133 early neonatal deaths. Perinatal mortality was 27% (95%IC = 23.7–29.6%). The causes of this mortality were respiratory distress (58.2%), neonatal infection (pneumonia and neonatal meningitis, 13.5%), complications of prematurity (9.0%), neonatal tetanus (1.6%), congenital malformations (0.6%). The cause of perinatal death was unknown for 17.1%. Risk factors for perinatal mortality were: unmarried mother; home delivery; complicated delivery; dystocia; caesareansection; multiple pregnancy; low birth weight; prematurity.
  
  
  CONCLUSIONS
  Action should be taken to improve availability, use and quality of Emergency obstetrical and neonatal care. Women should be better informed concerning the danger signs of pregnancy and childbirth.
