Summary

This study examined 893 pediatric asthma emergencies, finding a link between sulfur dioxide (SO2) levels and asthma crises in children over 3. Temperature influenced asthma in younger children, with higher incidence in February.

Area of Science:

  • Pediatric Emergency Medicine
  • Environmental Health
  • Respiratory Medicine

Background:

  • Asthma is a common chronic respiratory disease in children.
  • Environmental factors are suspected triggers for pediatric asthma exacerbations.
  • Understanding these triggers is crucial for effective management and prevention.

Purpose of the Study:

  • To investigate the correlation between asthmatic crises in children and environmental factors.
  • To analyze the influence of atmospheric contamination, meteorological data, and pollen levels on pediatric asthma.
  • To identify specific triggers for bronchospastic processes in different age groups.

Main Methods:

  • Retrospective analysis of 893 pediatric asthma emergency cases from 1983-1984.
  • Data collected included patient age, sex, and hospitalization rates.

  • Correlation analysis with atmospheric pollution (SO2), weather data, and pollen counts.

    • Main Results:

    • Highest incidence of asthma attacks observed during autumn.
    • No significant correlation found between asthma attacks and general meteorological data or pollen levels.
    • Significant association between asthmatic crises in children over 3 years old and sulfur dioxide (SO2) levels.
    • Bronchospastic processes in children under 3 years old were influenced by temperature, with higher incidence during colder months (February).

    Conclusions:

    • Atmospheric sulfur dioxide (SO2) may be a trigger for asthma exacerbations in children over 3 years old.
    • Temperature appears to influence asthma incidence in younger children (under 3).
    • Further longitudinal studies are recommended to confirm these findings and draw definitive conclusions.
