Abstract

Background: In spite of enormous investments in Malaria control programme, malaria is still a major cause of morbidity and mortality among under-fives. Objective: The objective of this study was to determine malaria parasitaemia in under-fives and to relate it to household use of Insecticide Treated Bed Nets (ITBNs) in Jos - a malaria endemic setting. Methodology: A cross-sectional study was carried out in a selected settlement in Jos North Local Government Area (LGA) in September 2007 towards the end of the rainy season. All households with children less than 5 years of age in the selected settlement were listed and then 150 of the households were selected using systematic sampling technique. In each selected household one under five was selected and where there were
more than one under five only one was selected by balloting. The selected 150 under-fives were then studied using thumb prick blood smear to determine the presence of malaria parasite in their peripheral blood and a semi structured interviewer administered questionnaire to obtain information on household use of ITBNs in the community. Result: Malaria parasitaemia was found in 57 (38.0%) of the children and the highest age specific prevalence of 46.4% was among the 36-47 months age group. The females were more (46.6%) infected than their male counterparts (29.9%) p=0.035. Eighty three (55.3%) mothers owned ITBNs but only 61(40.7%)
used them for their children. Children who slept under ITBNs were less likely to have malaria parasites in their blood compared with those who did not (p=0.000..). Mothers’ age and education were among other factors that positively influenced the use of ITBNs. Conclusion: Malaria parasitaemia is high in this community and sleeping under ITBN has been found to significantly reduce the prevalence of parasitaemia in the children studied. It is therefore recommended that the ITBNs campaign should be intensified so that the ITBN use can cover all the under-fives.
