Respiratory Exacerbations and their Association with Particulate Matter Fluctuations at Hugo Mendoza Pediatric Hospital

Introduction: Millions of children are exposed daily to air pollution, one of whose components is particulate matter, which is especially harmful to the pediatric population and can worsen the course of respiratory diseases.
Objective: To describe the association between respiratory disease exacerbations and particulate matter fluctuations at the Dr. Hugo Mendoza Pediatric Hospital, between 2017 and 2022.
Methods: An observational, analytical and longitudinal study was conducted using secondary data. The study population comprised 344 670 patients, with a sample size of 56 734 cases. A Poisson regression was performed to analyze the association between exacerbations of respiratory disease and particulate matter concentration.
Results: The findings indicated that the predominant respiratory exacerbation was bronchial asthma, mainly affecting children aged 1-2 years, mostly males. It was shown that for each unit increase in the average concentration of fine particulate matter and coarse particulate matter, exacerbations of respiratory diseases increased by 4,7% and 3,0%, respectively.
Conclusions: Bronchial asthma was the predominant disease with respiratory exacerbations, and a higher average concentration of particulate matter was significantly related to an increase in the number of respiratory exacerbations. These findings could have implications for a better understanding of the relationship between exposure to particulate matter and the frequency of respiratory exacerbations in our context, suggesting the need for environmental prevention and control measures to mitigate adverse effects on respiratory health.
