Air pollution slows lung growth during childhood, UK study shows
- Researchers followed over 5,000 people born in and around Bristol since the 1990s to assess lung growth across life stages.
- Higher air pollution exposure during pregnancy and early childhood slowed lung development into early adulthood.
- The greatest impact on lung growth occurred during adolescence, a period of accelerated development.
- Lung function was measured with spirometry by trained technicians to assess respiratory health.
- Pollution exposure estimates included particle pollution and nitrogen dioxide from traffic and fossil gas boilers.
- Even after accounting for prematurity and home conditions, pollution effects on lung growth remained relevant.
- The study links small early-life differences to potential long-term health risks.
- Lower childhood lung growth may increase vulnerability to respiratory and cardiovascular diseases later in life.
- Researchers emphasize reducing exposures to protect children's environments.
- The Bristol-based findings echo earlier work showing improved air quality can aid lung growth.
