Exercise-induced asthma in schoolchildren. A pilot study in two Haifa districts
Israel Journal of Medical Sciences
|January 1, 1985
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.
