Prevalence And Determinants Of Diarrhoea And Acute Respiratory Infections Among Children Aged Under Five Years In West Africa: Evidence From Demographic And Health Surveys

Abstract

Background: Diarrhoea and pneumonia are the leading causes of morbidity and mortality in children aged <5 years (under five) globally. This study sought to investigate the prevalence and determinants of diarrhoea and acute respiratory infections (ARIs) among children under five in West Africa. Methods: The most recent demographic and health survey (DHS) standard for 13 West African countries was used in the study. We calculated the prevalence of diarrhoea and ARIs (2 weeks prior to the survey) and performed multivariable complex logistic regression analysis to identify possible predictors of diarrhoea and ARIs. Results: The weighted prevalence of diarrhoea and ARI was 13.7% and 15.9%, respectively. The prevalence of comorbid diarrhea, and ARI was 4.4%. Children aged <2 y (p<0.001), mothers aged <30 y (p<0.003), mothers without formal education (p<0.001), poor households (p<0.001) and poor nutritional status, wasting (p = 0.005) and underweight (p<0.001), were the independent predictors of diarrhoea. The independent predictors of ARIs were children with no childhood vaccinations (p = 0.002), use of solid fuel in the household (p = 0.007), being underweight (p = 0.05) and diarrhoea (p < 0.001). Conclusions: The findings imply the need for holistic public health interventions such as increased vaccination coverage, population-based nutritional programmes and campaigns on the use of cleaner cooking fuel targeted at high-risk subgroups in the population to reduce the burden and adverse effects of diarrhoea and ARIs in the West African region.
