Abstract

What is already known about this topic?: The prevalence of COPD in Chinese individuals aged 50 years and above was obviously higher than that in younger adults, but the risk factors for this age group were unclear.

What is added by this report?: The prevalence was estimated at 12.8% and 5.7% for males and females over 50 in 2020-2021, with confirmed risk factors of cigarette smoking, a family history of respiratory diseases, respiratory symptoms, and a history of cough or respiratory diseases during childhood.

What are the implications for public health practice?: The findings may help clinicians and the public identify individuals at high risk of COPD and take targeted measures in a timely manner.

Keywords: China; Chronic Obstructive Pulmonary Disease; Risk Factor.
