The prevalence and risk factors for acute respiratory infections in children aged 0‐59?months in rural Malawi: A cross‐sectional study

摘要

Abstract BackgroundAcute Respiratory Infections (ARI) are a leading cause of childhood mortality and morbidity. Malawi has high childhood mortality but limited data on the prevalence of disease in the community. MethodsA cross-sectional study of children aged 0-59?months. Health passports were examined for ARI diagnoses in the preceding 12?months. Children were physically examined for malnutrition or current ARI. Results828 children participated. The annual prevalence of ARI was 32.6% (95% CI 29.3-36.0%). Having a sibling with ARI (OR 1.44, P =?.01), increasing household density (OR 2.17, P = .02) and acute malnutrition (OR 1.69, P = .01) were predictors of infection in the last year. The point prevalence of ARI was 8.3% (95% CI 6.8-10.4%). Risk factors for current ARI were acute-on-chronic malnutrition (OR 3.06, P = .02), increasing household density (OR1.19, P = .05) and having a sibling with ARI (OR 2.30, P = .02). ConclusionThis study provides novel data on the high prevalence of ARI in Malawi. This baseline data can be used in the monitoring and planning of future interventions in this population.
