				        	Objective:To survey and update the epidemiological data of chronic obstructive pulmonary disease (COPD) in people≥40 years old in Yinchuan City in the last 10 years.Methods:This was a cross-sectional study in which questionnaires and physical measurements were taken from April 2019 to December 2022 using multi-stage stratified whole population sampling of residents≥40 years in three districts, two counties, and one city in Yinchuan City. In this survey, 14 666 cases were extracted, and finally 11 547 cases with qualified lung function measurements and complete questionnaires were included in the analysis to obtain the basic information of the respondents, exposure to disease-related factors, symptoms related to COPD, disease awareness and lung function test rate, and logistic regression was used to analyze the risk factors of COPD.Results:A total of 11 547 cases were included in the study, and 1 841 patients with COPD were detected, giving an overall prevalence of COPD of 15.9%. The prevalence was higher in men (18.6%) than in women (12.9%); it was higher in urban areas (17.3%) than in rural areas (14.7%); and it was statistically significant that the prevalence of current smokers (24.4%) and ex-smokers (24.6%) was higher than the prevalence of non-smokers (13.0%) (all P<0.001) in those COPD patients. The prevalence rates of COPD in people aged 40-49, 50-59, 60-69, and ≥70 years were 11.7%, 12.9%, 16.9%, and 24.6%, respectively, which tended to increase gradually with age ( P<0.001). 10.5% of patients with COPD said they were aware of the disease and 17.4% received a pulmonary function test. The results of logistic regression analyses showed that the risk factors for COPD included male, advanced age, living in an urban area, low literacy, current smoking, former smoking, history of secondhand smoke exposure, low body weight, history of biomass fuel use, and family history of respiratory disease. Conclusions:The prevalence of COPD among people≥40 years in Yinchuan City is significantly higher than 10 years ago and is higher than the national data. However, the disease awareness rate is low, and active intervention of risk factors and enhancement of publicity are important measures to prevent and control the disease.
