Exercise-induced asthma in schoolchildren. A pilot study in two Haifa districts
Summary
Exercise-induced asthma prevalence was studied in Haifa schoolchildren. While slightly higher in a rural kibbutz near industry, the overall prevalence was 8.6% and decreased with age.
Area of Science:
- Pediatric Pulmonology
- Environmental Health
- Epidemiology
Background:
- Exercise-induced asthma (EIA) is a significant respiratory condition in children.
- Environmental factors, such as industrial pollution, may influence EIA prevalence.
- Understanding EIA prevalence in different environments is crucial for public health.
Purpose of the Study:
- To determine the prevalence of exercise-induced asthma in schoolchildren in Haifa.
- To compare EIA prevalence between urban and rural settings with varying pollution levels.
- To investigate the influence of age and sex on EIA prevalence.
Main Methods:
- A cross-sectional study was conducted on 313 schoolchildren in Haifa.
- Participants were divided into two groups: urban (unpolluted) and rural (near polluting industries).
- Asthma diagnosis and prevalence were assessed in both groups.
Main Results:
- The overall prevalence of exercise-induced asthma was 8.6%.
- Prevalence was marginally higher in the rural kibbutz group compared to the urban group, though not statistically significant.
- A trend of decreasing prevalence with increasing age was observed.
- No significant association was found between EIA prevalence and sex.
Conclusions:
- Exercise-induced asthma affects a notable percentage of schoolchildren in Haifa.
- While industrial proximity showed a trend towards higher prevalence, further research is needed to confirm significance.
- Age appears to be a factor in EIA prevalence, with younger children potentially being more affected.

Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
