Chinese Expert Consensus on the Impact of Ambient Air Pollution on Allergic Rhinitis and Recommendations for...

Ambient air pollution poses a significant yet manageable threat to human health. The growing consensus on the impact of ambient air pollutants on allergic rhinitis (AR) emphasizes the importance of prevention, control, and treatment strategies. A multidisciplinary consensus development group was established to further standardize management strategies for AR in the presence of exposure to ambient air pollutants. The quality of the evidence and the strength of the recommendations were evaluated using the grading of recommendations, assessment, development, and evaluation (GRADE) system based on domestic and international relevant medical evidence. This consensus evaluates the effects of key air pollutants on public health in relation to AR, including the synergistic effects of air pollutants with meteorological conditions and aeroallergens. At the same time, the consensus provides recommendations for targeted therapeutic and preventive measures for AR under conditions of ambient air pollution, aiming to improve AR-related health outcomes. These recommendations aim to increase public and clinical awareness of the contribution of environmental factors to AR, and offer evidence-based insights for policymakers and regulators to establish informed ambient air quality standards.
