Abstract: This study was carried out to assess the malaria prevalence and risk factors in children aged 6 – 59 months. The data used for the analysis was obtained from the 2018 Nigeria standard demographic and health survey (NDHS). The sample was obtained through a stratified two-stage cluster sampling. The sample consists of 10609 children aged 6 – 59 months. Members of the sample were tested for malaria parasite through rapid diagnostic test (RDT). Fourteen malaria risk factors were identified and subjected to screening Philips et al., (2009), Kanyangarara et al., (2016). The screening involves testing for multicollinearity and linearity in order to satisfy assumptions for binary logistic regression model. Three factors failed the test and eleven were included as independent covariates in the binary logistic regression analysis.
