Understanding Acute Respiratory Illness in Nepalese Children Under Five: Insights from the 2016 NDHS

Acute Respiratory Illness (ARI) remains a critical public health challenge for children under five in Nepal, with persistent socioeconomic inequities in disease burden. This cross-sectional study analyzed Nepals 2016 Demographic and Health Survey (n=4,887) to identify determinants of ARI using caregiver reported symptoms of rapid breathing and chest-related issues within two weeks of the survey. Weighted logistic regression analyses examined associations between ARI and variables such as wealth quintile, residence type, maternal education, and child age. Nationally, ARI prevalence stood at 2.41%, with pronounced disparities: children from the poorest wealth quintile had 5.6x higher prevalence than the richest (3.32% vs 0.59%), while Province 6 reported the highest regional burden (3.37%). Multivariate analysis confirmed household wealth as the significant predictor (AOR=1.60, 95% CI:0.063-40.836), though wide confidence intervals indicated model overdispersion. Notably, 84.92% of caregivers sought healthcare--primarily through private facilities (32.30%) and pharmacies (27.92%)--highlighting gaps in public sector utilization These findings reveal wealth-based health disparities despite Nepals progress toward SDG child mortality targets. The results advocate for province-specific interventions in high-burden regions like Province 6, including mobile pneumonia clinics and biomass fuel transition programs. Socioeconomic disparities play a key role in ARI prevalence among children under five in Nepal. Interventions aimed at reducing care-seeking fragmentation while targeting poverty-alleviation strategies to reduce ARIs disproportionate impact on marginalized populations could be beneficial. Future research should focus on identifying additional risk factors that were not looked into by the NDHS survey and evaluating targeted prevention strategies.
