Insights
Understanding childhood asthma is improving. Key risk factors like gender, genetics, and pollution are clearer, aiding prognosis for preschool and older children toward persistent or adult asthma.
Area of Science:
- Pediatric Pulmonology
- Epidemiology of Respiratory Diseases
Background:
- Asthma natural history understanding is advancing.
- Precise asthma definitions and longitudinal studies enhance knowledge.
- Childhood asthma risk factors are increasingly recognized.
Purpose of the Study:
- Review risk factors for asthma evolution in children.
- Discuss prognosis for preschool asthma progressing to persistent childhood asthma.
- Analyze risk factors for older children's asthma progressing to adult asthma.
Main Methods:
- Literature review of large-scale longitudinal studies.
- Analysis of established risk factors for asthma development.
- Examination of asthma progression pathways in different age groups.
Main Results:
- Identified key risk factors: gender, atopy, genetics, infections, pollution.
- Preschool asthma prognosis linked to specific risk factors for persistence.
- Older children's asthma prognosis associated with factors leading to adult asthma.
Conclusions:
- Improved understanding of asthma's natural history aids early intervention.
- Risk factor identification is crucial for predicting asthma persistence and progression.
- Targeted strategies can be developed based on age-specific asthma pathways.
Abstract:
Current knowledge of the natural history of asthma is improving through the establishment of a more precise definition of asthma linked with information from a number of large-scale longitudinal studies. Risk factors for the development of childhood asthma are now more clearly understood. They include gender, atopic status, genetic and familial factors, respiratory infections, and outdoor and indoor pollution (1). In the present review two types of asthma and their prognosis will be discussed: (1) Asthma in preschool children and its risk factors for evolution towards persistent childhood asthma. (2) Asthma in older children and its risk factors for evolution towards adult asthma.
