title: Malaria prophylaxis and the reduction of anemia at childbirth.
abstract: OBJECTIVE
  To assess the effect of introducing chloroquine prophylaxis during pregnancy on prevalence of anemia (<10.9 g/dl) at childbirth and perinatal outcome.
  
  
  METHODS
  Observational study in a rural district hospital in Ghana, which compared 2803 women who received chloroquine prophylaxis during pregnancy with 3084 historical controls, who had not received prophylaxis during pregnancy. Main outcome measures were hemoglobin level at childbirth, perinatal mortality and birth weight.
  
  
  RESULTS
  Mean hemoglobin level before childbirth increased from 10.7 g/dl (S.D.=1.0 g/dl) to 11.0 g/dl (S.D.=0.9 g/dl). Prevalence of anemia decreased from 29.4 to 13.3% (OR=0.4 and 95% CI=0.3-0.4). Prevalence of moderately severe anemia (<9.0 g/dl) decreased from 4.4 to 3.3% (OR=0.7, 95% CI=0.6-0.97). Perinatal mortality and low birth weight (<2500 g) remained unchanged.
  
  
  CONCLUSIONS
  Routine chloroquine prophylaxis in pregnancy is useful in reducing anemia at childbirth in malaria-endemic regions. Fetal outcome did not improve with chloroquine prophylaxis in this study.
