Abstract
Information about the decline rate in forced expiratory volume in 1 s (FEV1s) in older adults with COPD is scarce. A total of 4082 community-dwelling older adults from the population-based study Good Aging in Skåne were followed for 12 years and 143 participants developed COPD. The average FEV1s decline is estimated to be 66.3 mL/year, (95% CI [56.4; 76.3]) and 43.3 mL/year (1.7%/year, 95% CI [41.2; 45.5]) for COPD and non-COPD participants, respectively.
