Late Breaking Abstract - Accelerated lung function decline in former and light smokers: NHLBI Pooled Cohorts Study

Background: Limited data suggest normalization of lung function decline with smoking cessation and slower decline with smoking reduction; yet, mechanistic studies suggest ongoing risk. Aims: To test whether former and “light” smoking are associated with accelerated lung function decline compared to never smoking. Methods: The NHLBI Pooled Cohorts Study harmonized spirometry and other measures from US population-based...
