A new report developed within the ClimAIr project brings together current evidence on the short-term effects of outdoor air pollution on allergic rhinitis. By reviewing epidemiological studies conducted in different geographical settings and population groups, it describes how variations in ambient air quality are associated with symptom control and healthcare use.
Understanding Air Pollution and Allergic Rhinitis
The review, titled “Review article on the effect of air pollution on airway allergy with a focus on vulnerable populations”, provides an overview of how environmental factors, including air pollutants and climate-related conditions, influence airway allergy outcomes. Allergic rhinitis is described as an IgE-mediated inflammatory disease of the upper airways, associated with nasal symptoms and a significant impact on quality of life and healthcare use.
Methodology
The report is based on a systematic search of the PubMed database and includes 30 original studies assessing short-term effects (up to seven days after exposure) on symptom control and healthcare use. The studies were mainly conducted in China, with others carried out in Europe and additional regions.
Key Findings and Conclusion
Overall, the evidence supports an association between short-term exposure to outdoor air pollution and poorer symptom control in allergic rhinitis. The report highlights the importance of integrated air-quality management and climate-adaptation strategies, as well as priorities for future research.
