Prevalence Of Malaria Parasitaemia In Pregnant Women Attending Antenatal Clinic At Jos University Teaching Hospital, Nigeria

The prevalence of malaria parasitaemia in 200 pregnant women attending the antenatal clinic (ANC) of Jos University Teaching Hospital (JUTH) between April and June 2003 was determined. Geimsa-stained thick and thin blood films were examined microscopically for malaria parasites; the parasite densities were determined on the thick films. Eighteen (9%) of the women were positive for malaria parasites and only Plasmodium falciparum was encountered in the study. Pregnant women in the 15-20 year age group recorded the highest prevalence of 16%, closely followed by the age group 21-25 years with 15.2%. The 26-30, 31-35, 36-40 and 41-50 year age groups recorded 6.7%, 4.5%, 4.1% and 0% prevalence rates respectively. Women in their first trimester recorded 13.3% as against 10.2% and 3.8% for the second and third trimester respectively. The primigravidae had a prevalence of 12.9% as against 7.2% for multigravidae. Most of the women with malaria parasitaemia (89%) had parasite densities of less than 1000/μL of blood. The low prevalence of malaria parasitaemia in the ANC women is attributed to the regular prophylactic malaria therapy and the impacts of the health talks normally given to pregnant women during routine antenatal visits
