1. How does changing the diagnostic criteria of COPD from fixed FEV1/FVC < 0.7 to a lower limit of normal impact rates of prevalence?

Chinese researchers found that using the Guangzhou Institute of Respiratory Health’s criteria for the lower limit of normal resulted in slightly higher rates of COPD in women, rural patients, and younger non-smoking samples as compared to their respective prevalence rates using the global standard of a 0.7 fixed ratio).

2. How have rates of COPD in the United States changed between 2012 and 2018, and to what can this change be attributed?

After adjusting for age, the researchers concluded that 4.1% of workers had diagnosable COPD. The prevalence rate varied based on industry and occupation.
