Air pollution has been associated with poor asthma control in children and is a potentially modifiable risk factor for decreased lung function, the use of rescue medications, and higher asthma-related healthcare usage. To enhance child health, it is necessary to identify the most significant pollutants to asthma, as well as susceptibility factors and measures for reducing exposure. The existing body of evidence supports the link between pollution and poor asthma outcomes. Ethnicity, socioeconomic position, and the existence of specific gene variants may all influence susceptibility to the harmful effects of air pollution on health.
Better asthma outcomes were related to higher air quality requirements.
Recent relevant evidence supports the relationship between air pollution and paediatric asthma morbidity. Continued efforts are required to identify the most susceptible groups and create methods for reducing exposures and improving air quality.
