Summary
Exercise-induced asthma (EIA) affects nearly 9% of schoolchildren. Recent asthma symptoms and allergic rhinitis are significant risk factors for developing EIA.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
- Sports Medicine
Background:
- Exercise-induced asthma (EIA) is a common condition in children.
- Accurate diagnosis and identification of risk factors are crucial for effective management.
Purpose of the Study:
- To determine the prevalence of EIA in schoolchildren aged 12-13.
- To identify potential risk factors associated with EIA in this population.
Main Methods:
- A population of 201 schoolchildren underwent a 6-minute free run in a gymnasium.
- Peak expiratory flow rate (PEFR) was measured pre- and post-exercise.
- Parental questionnaires assessed asthma history, recent symptoms, and allergic rhinitis.
Main Results:
- EIA was identified in 8.9% of the studied children.
- Children with symptomatic asthma had a significantly higher prevalence of EIA (43%) compared to asymptomatic children.
- Allergic rhinitis was also associated with a higher incidence of EIA (14.6%).
Conclusions:
- Recent asthma symptoms and allergic rhinitis are identified as significant risk factors for EIA.
- Screening for EIA in a gym class setting is feasible and can aid diagnosis and treatment.
