Abstract

Malaria and anemia are common in pregnant African women. We screened 4,764 Malawian women at first antenatal visits for malaria and anemia. A total of 42.7% had a malaria infection, which was more common and of higher density in primigravidae (prevalence = 47.3%, geometric mean = 332 parasites/microl) and teenagers (49.8%, 390/microl) than in multigravidae (40.4%, 214/microl) or older women (40.6%, 227/microl).

Prevalences of malaria and anemia were highest in the rainy season. Women with moderat..
