The prevalence of malaria parasitaemia/anaemia in pregnancy, were determined during two
malaria transmission seasons in rural Idah and Igalamela-Odolu Local Government Areas of Kogi
State. In each survey, questionnaires were administered on previous parity history, gestational age
and malaria parasitaemia were determined. A total of 797 pregnant women were enrolled in five
(5) major clinics attended by pregnant women. A total of 384 (48.2%) that had microscopic
parasitaemia were interviewed using questionnaires. There were more positive cases among
primigravidae, and the results showed a significant difference (P<0.05) between the primigravidae
and multigravidae, but show no significant difference (P>0.05) between the trimesters. More
