Abstract：Objective To investigate the prevalence and influencing factors of chronic obstructive pulmonary disease (COPD) among residents at ages of 40 years and older in Qidong City, Jiangsu Province, so as to provide insights into COPD prevention and control. Methods Permanent residents at ages of 40 years and older were sampled using a multistage stratified random sampling method in Qidong City in 2020, and subjects' demographics, history of environmental contact, and medical and family history of respiratory disorders were collected. Pulmonary function test was performed, and the forced expiratory volume (FEV1)/forced vital capacity (FVC) ratio of <70% was defined as COPD. Factors affecting the prevalence of COPD were identified using a multivariable logistic regression model. Results A total of 8 000 questionnaires were allocated, and 7 538 valid questionnaires were recovered, with an effective recovery rate of 94.23%. The respondents included 3 104 men (41.18%) and 4 434 women (58.82%), and had a mean age of (62.40±14.68) years. The prevalence of COPD was 15.06%. Multivariable logistic regression analysis showed that male (OR=1.818, 95%CI: 1.712-1.940), age (50 to 59 years, OR=1.142, 95%CI: 1.111-1.181; 60 to 69 years, OR=1.176, 95%CI: 1.142-1.219; 70 to 79 years, OR=1.300, 95%CI: 1.249-1.361; 80 years and older, OR=1.582, 95%CI: 1.490-1.691), smoking (OR=3.760, 95%CI: 2.658-4.879), alcohol consumption (OR=1.213, 95%CI: 1.077-1.348), use of solid fuels (OR=1.676, 95%CI: 1.591-1.773), history of occupational exposure to dust (OR=1.859, 95%CI: 1.752-1.982), medical history of asthma or dyspnea (OR=2.068, 95%CI: 1.044-3.125) and frequency of persistent cough of more than four times annually (OR=1.225, 95%CI: 1.121-1.345) were statistically associated with the prevalence of COPD among residents at ages of 40 years and older in Qidong City. Conclusion The prevalence of COPD was 15.06%, and was associated with gender, age, smoking, use of solid fuels, occupational exposure to dusts, medical history of asthma or dyspnea and frequency of persistent cough among residents at ages of 40 years and older in Qidong City.
