Insights
Childhood asthma prevalence varies globally, with higher rates in Oceania and the British Isles compared to Asia and Africa. Further research is needed to understand and standardize childhood asthma prevalence worldwide.
Area of Science:
- Pediatrics
- Epidemiology
- Public Health
Background:
- Growing evidence suggests an increase in childhood asthma frequency globally.
- International comparisons of asthma prevalence are challenging due to varied methodologies and definitions.
Purpose of the Study:
- To provide a global overview of published studies on childhood asthma prevalence.
- To highlight geographical variations and trends in childhood asthma worldwide.
Main Methods:
- Systematic review of existing literature on childhood asthma prevalence.
- Analysis of prevalence data across different continents and regions.
Main Results:
- Oceania reports the highest childhood asthma prevalence globally, followed by the British Isles.
- European countries show varied prevalence, with higher rates in the British Isles than continental Europe (except Switzerland).
- Spain's national prevalence is lower than surrounding countries, but regional variations exist.
Conclusions:
- Childhood asthma is increasing globally, despite geographical differences in its occurrence.
- Standardizing measurement tools and investigating the causes of increased prevalence are crucial.
- Addressing the global rise in childhood asthma requires international collaboration and research.
Background:
at the moment there is a considerable interest in the international comparison of the bronchial asthma prevalence, stimulated by the growing evidence of an increment in the frequency. The comparison among studies of bronchial asthma prevalence present the problem of the varied and different methodologies used by the authors, as well as of the lack of a clear definition of what is considered bronchial asthma.
Methods:
in this work we try to offer a global vision of the studies published on childhood asthma prevalence in the world.
Conclusions:
in the studies carried out at European level, they highlight the high figures found in the British Islands superiors to those referred in the countries from the continent to exception of those observed in Switzerland. In Spain the figures of the studies carried out at national level are something below the countries of our environment, although there have been higher figures in studies carried out in Barcelona and Huelva. In Oceannia they are observed from all over the world in general the highest figures, above the American countries and very above the countries of Asia and Africa to exception of South Africa. Although there are considerable geographical differences in its presentation, bronchial asthma is an illness in constant increase in the entire world. It is for this reason that efforts should be carried out in the search of the causes of this increment, as well as in the standardization of the instruments of measure of the appearance of the illness.
