Does Socioeconomic Environment Is A Risk Factor For Malaria In Senegal ? A DHS Data Analysis of Malaria Trends From 2010 To 2016 In Senegal

Abstract Introduction Analysis of the evolution of malaria will help address the determinants of malaria elimination in this country. The aim of this study is to analyze the evolution of malaria in Senegal from 2010 to 2016.MethodsThis article uses data from the Senegalese Demographic and Health Surveys (for 2010-2011, 2012-2013, 2014, 2015 and 2016. To assess the factors associated with the positivity of the RDT, a multivariate logistic analysis was conducted to account for the effect of confounding factors. Adjusted odds ratios were calculated with their 95% confidence intervals. The dependent variable was the result of the Malaria rapid diagnostic test. ResultsThe malaria prevalence rate varies from 3.01% in 2010 to 0.87% in 2016. The risk factors associated with the evolution of malaria were the age of the child (4 years (aOR=1.82 [1.14-2.89]) and 5 years (aOR=1.98 [1.21-3.25]). The richest wealth quintile was a protective factor against malaria with aOR=0.02 [0-0.18]. Other protective factors against malaria were the construction characteristics of the houses. These are houses with improved wall and roof materials with aOR 0.45 [0.24-0.85] and 0.48 [0.25-0.93] respectively.Conclusion Factors associated with the evolution of malaria in Senegal are children’s age, level of wealth of the household and type of dwelling in the house. It should be noted that the level of development of countries, by influencing better living conditions for communities, remains an important prerequisite for the elimination of malaria in the African sub region and in Senegal in particular.
