Associations of improved air quality with lung function growth from childhood to adulthood: the BAMSE study

BACKGROUND: The beneficial effect of improving air quality on lung function development remains understudied. We assessed associations of changes in ambient air pollution levels with lung function growth from childhood until young adulthood in a Swedish cohort study. METHODS: )) at residential addresses were estimated using dispersion modelling. Linear mixed effect models were used to estimate associations between air pollution exposure change and lung function development. Associations persisted after adjustment for potential confounders and were not modified by asthma, allergic sensitisation, overweight, early-life air pollution exposure or dietary antioxidant intake. CONCLUSIONS: Long-term reduction of air pollution is associated with positive lung function development from childhood to young adulthood.
