title: Risk factors of neonatal anemia in placenta previa.
abstract: OBJECTIVE
  Placenta previa is a major cause of neonatal anemia. The purpose of this study was to elucidate the risk factors of neonatal anemia in placenta previa.
  
  
  METHODS
  The study was conducted on 158 placenta previa patients at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 through December 2009. The subjects were divided in to 2 groups: 47 placenta previa patients with neonatal anemia, and 113 placenta previa patients without neonatal anemia. The subjects' characteristics were compared. Logistic regression was used to control for confounding factors.
  
  
  RESULTS
  Anterior placental location (OR 2.48; 95% CI: 1.20-5.11) was an independent risk factor of neonatal anemia after controlling for potential confounders.
  
  
  CONCLUSIONS
  To manage neonatal anemia in placenta previa patients, obstetricians should do their best to detect placental location. Pediatricians should consider the high possibility of neonatal anemia in cases involving anterior placental location.
