Abstract
Objective: This study aimed to critically synthesize the available scientific evidence on the association between environmental factors and the incidence of pediatric epistaxis. Methods: A systematic review with meta-analysis of observational studies was conducted, assessing the relationship between meteorological variables or air pollutants and pediatric epistaxis cases. Articles published between 2018 and 2024 were included, with no geographical restriction. Results: Over 250,000 pediatric cases were analyzed. A positive correlation was found between epistaxis and increased average temperature, solar exposure, and ozone (O₃) levels. Atmospheric pressure, carbon monoxide (CO), and sulfur dioxide (SO₂) showed inverse correlations. Age, allergic rhinitis, and socioeconomic status were identified as relevant risk modifiers. Conclusion: Pediatric epistaxis exhibits a seasonal pattern and is associated with environmental and social factors. Preventive strategies and integrated public health policies are recommended during high-risk periods.
