Lung development and respiratory disease from childhood to adulthood

Childhood asthma persisting into adult life is associated with long-term lung function deficits and to an increased susceptibility to non-reversible airflow limitation, the hallmark of chronic obstructive pulmonary disease.

This project aims to investigate long-term respiratory and allergy outcomes in relation to early life disease, environmental exposure and genetic/epigenetic factors. The aim is also to establish a three-generation cohort with BAMSE parents, participants and their offspring for analyses of trans-generational hereditary and environmental effects.

The BAMSE birth cohort was initiated in 1994-96 and this application includes plans for a new BAMSE follow-up 2017-18 when the participants will be 22-24 years of age (“BAMSE24”). This follow-up will allow for analyses of lung function trajectories up to adult age and identification of key determinants, as well as identification of prognostic factors and biomarkers for disease onset, progress or remission. We will use omics- and environment exposure data for causal inference analyses on lung function, respiratory and allergic disease that will enable analyses from association to causation and clinical implication.

This project will provide knowledge about potential strategies to prevent childhood allergy, asthma from becoming chronic severe diseases in adulthood. In addition, our results may allow for identification of new candidates for drug development.
