Prevalence of malaria and anaemia in pregnancy in Ibadan, South-western Nigeria
AbstractThe study investigated the episode of malaria infection and anaemia in pregnancy of 226 women. The overall prevalence of malaria infection among pregnant women was 23.08%, while only 7.1% of non-pregnant women were malaria positive. The mean parasite density was significantly higher in the primigravidae than in the multigravidae (3144±107 versus 1014±158; p<0.05). The mean parasite densities were significantly higher in both primigravidae and multigravidae than in the non-pregnant control (3144±107 and 1014±158 respectively versus 101±70; P<0.05). The mean haemoglobin (Hb0 concentration was significantly higher in the malaria negative non-pregnant control than in the malaria negative primigravidae (12.60±1.01versus 10.33±1.40; p>0.05), but there was no significant difference between the mean Hb concentration of malaria negative non-pregnant women and malaria negative pregnant women (12.60±1.01versus11.01±1.06p>0.05). The haemoglobin concentration was significantly higher in malaria positive non-pregnant controls than in the malaria positive primigravidae (11.56±1.01 versus 9.85±1.85p<0.05), but not significantly higher than that of the malaria positive multigravidae (11.56±1.01versus 10.45±1.45). Primigravidae were found to be more susceptible to malaria infection and severe anaemia than the multigravidae, hence, primigravidae are considered to need more medical attention than the multigravidae.
