Abstract：OBJECTIVE To investigate the epidemiological characteristics and risk factors of chronic obstructive pulmonary disease(COPD)in high-risk populations in Heilongjiang Province,providing evidence for policy formulation.METHODS Using stratified cluster random sampling,41 474 permanent residents were recruited from 6 monitoring sites(Harbin,Jixi,Heihe,Shuangyashan,Mudanjiang,Qiqihar)in Heilongjiang Province between May 2022 and December 2023.Data were collected through electronic questionnaires.High-risk individuals were defined as those scoring ≥16 on the COPD-SQ(Chronic Obstructive Pulmonary Disease Screening Questionnaire).Logistic regression analysis was conducted to examine risk factors.RESULTS Among the participants,6 961 individuals(16.78％)were identified as high-risk,with higher prevalence in males and significant increases after age 50.Regional disparities were observed,with Shuangyashan showing the highest prevalence(21.57％)and Mudanjiang the lowest(6.79％).Key risk factors included smoking,exposure to biofuels,and low body weight,with smoking being the most significant.CONCLUSION Identifying high-risk populations and regions in Heilongjiang Province,along with emphasizing biofuel exposure control,smoking cessation,and nutritional improvement for underweight individuals,will facilitate targeted interventions and policy development.
