Abstract
To explore how nutritional status impacts treatment efficacy and future asthma risk in infants with bronchiolitis. A retrospective analysis of 473 RSV-induced bronchiolitis cases from 2015 to 2018. No significant demographic differences. Obese infants showed increased respiratory distress, wheezing, and rapid breathing, with lower oxygen saturation. Elevated IgE and tumor necrosis factor-α (TNF-α) levels persisted in the obese group. A higher asthma incidence was observed after 5 years in this group. Nutritional status is crucial for bronchiolitis management; obesity prevention should be highlighted in asthma programs.
