Abstract
OBJECTIVES: This study aimed to analyze any reported antibiotic use for children aged <5 years with fever, diarrhea or cough with fast or difficult breathing (outcome) from low-income and middle-income countries (LMICs) during 2005-2017 by user characteristics: rural/urban residence, maternal education, household wealth, and healthcare source visited. METHODS: Based on 132 demographic and health surveys and multiple indicator cluster surveys from 73 LMICs, the outcome by user characteristics for all country-years was estimated using a hierarchical Bayesian linear regression model. RESULTS: Across LMICs during 2005-2017, the greatest relative increases in the outcome occurred in rural areas, poorest quintiles and least educated populations, particularly in low-income countries and South-East Asia. In low-income countries, rural areas had a 72% relative increase from 17.8% (Uncertainty Interval (UI): 5.2%-44.9%) in 2005 to 30.6% (11.7%-62.1%) in 2017, compared to a 29% relative increase in urban areas from 27.1% (8.7%-58.2%) in 2005 to 34.9% (13.3%-67.3%) in 2017. Despite these increases, the outcome was consistently highest in urban areas, wealthiest quintiles, and populations with the highest maternal education. CONCLUSION: These estimates suggest that the increasing reported antibiotic use for sick children aged <5 years in LMICs during 2005-2017 was driven by gains among groups often underserved by formal health services.
