Background: Pregnant women in endemic area may experience malaria infection without clinical symptoms. Its effects on the neonatal outcomes mayalso occur in this asymptomatic state.
Objective: To determine the prevalence of asymptomatic malaria parasitaemia in pregnancy and the relationship between the level of malaria parasitaemia and foetal birth weight.
Materials And Methods: A total of 290 asymptomatic paturients and their babies were recruited over 4 months with informed consent. The maternal, placenta and cord blood samples were obtained and examined for level of malaria parasitaemia. New-borns were weighed and classified as normal birth weight (?2500 g) or LBW (<2500 g).Pearson correlation was used to determine the relationship between the levels of malaria parasitaemia and birth weights. Student’s t and Pearson chi-square tests were used to compare means and percentages.
Results: The prevalence of malaria parasitaemia was 32.8%, 31% and 24.1% in the maternal, placental and cord blood smear respectively. The prevalence of low birth weight was 12.1% with women with malaria delivered more LBW babies (31.6%) than their uninfected counterparts (2.6%) (p=0.006). However, correlation showed a weak positive correlation between the levels of maternal parasitaemia(r = 0.163; p=0.504) and cord blood parasitaemia(r = 0.244; p = 0.400) but weak negative correlation with the level of placental parasitaemia (r = 0.135; p= 0.598) and foetal birth weight which were not statistically significant.
Conclusion: There was no significant correlation between the level of malaria parasitaemia and birth weight in asymptomatic parturients. However, the main impact on pregnancy outcome was the higher prevalence of LBW.
