Abstract:

Objective    To obtain the prevalence of chronic obstructive pulmonary disease (COPD) in urban residents in Jinan， to learn the status of diagnosis and treatment and to explore the possible related risk factors.   Methods    A cross-sectional study with a multistage stratified random sampling method was performed to select subjects aged ≥ 40 years. A questionnaire, designed with reference to the epidemiological questionnaire made by the program of COPD burden of GOLD committee and the practical situation of China, was used in interviews of the subjects. Then the CHEST HI-801 spirometer was used to test lung function in those who finished the questionnaire. The diagnosis of COPD was based on the standard made by the COPD group of Chinese Medical Association (2007 version). Results    According to the sampling rule, 2467 subjects should be included, among whom 2055 subjects finished the questionnaire and spirometry. The overall prevalence of COPD in urban residents in Jinan was 7.6%(156/2055), 12.2%(111/156) in males and3.9%(45/156) in females. 84 cases had been confirmed, in which only 37 (44.0％) cases accepted regular treatment,  and 48（30.8%） cases were asymptomatic. Multivariate logistic regression analysis found that the main factors affecting the state of COPD were smoking, males, senility, low income and a family history of respiratory diseases.  Conclusion    The overall prevalence of COPD in urban residents aged ≥ 40 years in Jinan was 7.6%. The actual state of diagnosis and treatment is far from satisfactory. Risk factors of COPD are related to individuals, family, and society.
