The importance of the period of malarial infection during pregnancy on birth weight in tropical Africa.

Malaria in pregnant women is related to low birth weight (LBW), a factor contributing to infant mortality. Which period of infection during pregnancy leads to the most harmful consequences is unclear. We analyzed data collected in Burkina Faso for 1190 pregnant women.

Is malarial placental infection related to peripheral infection at any time of pregnancy?

Placental infection measured by placental smear at delivery is a standard indicator, widely used to characterize malaria infection in pregnant women. However, a single measure can hardly reflect the entire history of infection during pregnancy. To investigate the relation between this indicator and peripheral infection during pregnancy, we used data collected in a randomized trial of malaria prophylaxis in 928 pregnant women in Burkina Faso, 1987-1988, during which repeated measures of peripheral infection were taken.

Effect of chloroquine prophylaxis during pregnancy on maternal haematocrit.

Two controlled trials of chloroquine prophylaxis during pregnancy were performed, one in Burkina Faso in 1987, on all pregnant women, and the other in Cameroon in 1992, on primigravidae only. Maternal haematocrit at delivery was found to be significantly higher in those women who had received chloroquine than in those who had not, both in Burkina Faso (37.4% v.
