Green space, air pollution, traffic noise and mental wellbeing throughout adolescence: Findings from the PIAMA study

The odds of poor mental wellbeing decreased with increasing exposure to green space in a 3000 m buffer (adjusted odds ratio 0.78 per IQR increase in average NDVI).

• Higher exposure to green space is linked to lower odds of poor mental wellbeing in adolescents aged 11 to 20 years.
• The association with green space remains significant even after considering air pollution and traffic noise.
• In smaller buffers of 300 m and 1000 m, the relationship between green space and mental wellbeing is less consistent.
• Increased exposure to air pollution is associated with higher odds of poor mental wellbeing, though this association weakens when accounting for green space.
• Traffic noise exposure does not show a relationship with mental wellbeing across the adolescent years.
