abstract
This study aimed to evaluate maternal knowledge of acute respiratory infections (ARI) in children under five years old and identify associated factors at Tay Nguyen Regional General Hospital. A cross-sectional study was conducted in 2023 among 206 mothers using a structured, validated questionnaire. Results showed that only 30.6% of mothers had correct overall knowledge. While understanding of symptom recognition (78.2%), feeding practices (96.1%), and prevention (88.4%) was relatively high, knowledge of severe symptoms (20.4%), need for medical attention (25.2%), and nasal hygiene (24.3%) remained poor. Logistic regression revealed that younger mothers and those with lower education levels were significantly less likely to possess accurate knowledge (p< 0.05). These findings underscore the need for targeted educational interventions, especially for vulnerable groups, to improve ARI-related knowledge and reduce disease burden among children.
