Prevalence and factors associated with acute respiratory infection among under-five children in selected tertiary hospitals of Kathmandu Valley

BACKGROUND: Acute respiratory infection (ARI) is responsible for about 30–50 percent of visits to health facilities and for about 20–30 percent of admissions to hospitals in Nepal for children under 5 years old. Incidence of ARI in children among under-five years of age is 344 per 1000 in Nepal. Hence, the study aims to find out the prevalence and factors associated with acute respiratory infection among under-five children. METHODS: A cross-sectional study was conducted at Nepal Medical College and Teaching Hospital and International Friendship Children’s Hospital (IFCH) in Kathmandu among children of age 2–59 months attending Pediatric OPD. A total of 286 children were selected using the non-probability (convenient) sampling technique. Data were collected using pre-tested semi-structured tool through interview schedule, and descriptive and inferential statistical analyses were used. RESULTS: Out of 286 children, more than half of children (60.8%) had Acute Respiratory Infection (ARI). Nearly one-fifth of the children had severe or very severe pneumonia. Acute respiratory infection was significantly associated with religion followed by the family (p = 0.009, OR = 4.59 CI = 1.47–14.36), presence of the child in the kitchen while cooking (p = 0.001, OR = 2.03 CI = 1.17–3.51), and presence of respiratory tract infection in family (p = <0.001 OR = 2.83 CI = 1.59–5.05). CONCLUSION: The study concluded that male children are more susceptible to acute respiratory infection than female children. Parents and family members should be aware of the prevention of acute respiratory infection by addressing and minimizing the factors contributing to ARI.
