Exploring the Impact of Air Pollution on Respiratory Health: Insights from ERS 2026
The European Respiratory Society (ERS) 2026 Congress brought together researchers, clinicians, and public health professionals from around the world to share the latest advances in respiratory health research. We were delighted to contribute to these discussions through the presentation of new findings from the PICNIC study, exploring how air pollution may affect respiratory outcomes in children.
Investigating Air Pollution and Childhood Respiratory Health
At the congress, Amal Rammah presented a poster examining the relationship between exposure to fine particulate air pollution (PM2.5) during childhood and the risk of wheeze and asthma among children with a history of bronchiolitis in Scotland.
Bronchiolitis is one of the most common respiratory infections affecting infants and young children and has been associated with an increased risk of developing respiratory problems later in childhood. However, less is known about how environmental exposures, such as air pollution, may influence respiratory outcomes among children who have already experienced bronchiolitis.
Findings from the PICNIC Study
Using data from the PICNIC study, the research explored whether childhood exposure to PM2.5 was associated with subsequent wheeze and asthma in this potentially vulnerable population.
The study contributes to a growing body of evidence suggesting that environmental exposures can play an important role in children’s respiratory health. By focusing on children with a history of bronchiolitis, the research provides valuable insights into how air pollution may affect those who may already be at increased risk of respiratory disease.
Why This Research Matters
Air pollution remains a major public health concern, particularly for children whose lungs and immune systems are still developing. Understanding how environmental exposures interact with early-life respiratory conditions is essential for identifying opportunities to prevent disease and improve long-term health outcomes.
Research such as this can help inform policies aimed at reducing children’s exposure to harmful air pollutants and contribute to broader efforts to create healthier environments for future generations.
Advancing the Conversation on Child Health
Presenting this work at ERS 2026 provided an important opportunity to share findings with an international audience of respiratory health experts and to contribute to ongoing discussions about the environmental determinants of respiratory disease.
We are proud to see the PICNIC study helping to advance understanding of how air pollution shapes children’s health and wellbeing. As evidence continues to grow, studies like this play an important role in supporting public health action and improving respiratory health outcomes for children.
The presentation highlights the importance of considering environmental exposures alongside clinical and early-life factors when seeking to understand and prevent childhood respiratory disease.
