Prevalence of Child Fever, Acute Respiratory Infection, and Diarrhea and Their Risk Factors in Sierra Leone

Abstract

Sierra Leone has the fourth-highest child mortality rate in Sub-Saharan Africa. This retrospective study aimed to estimate the nationwide prevalence of fever, acute respiratory infection (ARI), and diarrhea in children under 5 years in Sierra Leone, and to identify the risk factors associated with these diseases. We extracted patient information from the 2019 Sierra Leone Demographic and Health Survey data. Data were analyzed using multivariate logistic regression. In total, 8659, 8652, and 8650 children were included in the analyses of fever, ARI, and diarrhea, respectively. The analysis revealed that the nationwide prevalence rates of fever, ARI, and diarrhea were 16.8%, 14.2%, and 7.2%, respectively. Children aged 12–23 months were found to be the most susceptible. Compared to children consuming unimproved water, the highest prevalence rates of fever, ARI, and diarrhea were observed among children residing in households with tube wells or boreholes. The adjusted odds ratio for diarrhea prevalence among children drinking water from household tube wells or boreholes was 1.47 (95% confidence interval: 1.17–1.84, p < 0.001). This study has several limitations, including recall bias due to parental reporting. We suspect that the diseases may be associated with potential water contamination in tube wells or boreholes. We recommend national-level periodic inspections of water quality and community-level education on water supply management.
