Objective To investigate the prevalence of chronic obstructive pulmonary disease (COPD) and related risk factors in two districts and five counties in Jiaxing city of Zhejiang province. Methods We randomly selected people over the age of 40 in 10 communities of two districts and five counties in Jiaxing city by cluster sampling and random sampling to investigate the prevalence of COPD from January 2013 to December 2013. All included patients received pulmonary function test at the same time. Results A total of 1 256 cases of adults over the age of 40 were included, among which, 1 056 cases with complete data and qualified for pulmonary function test. There were 410 males with mean age of 58.74±11.62, and 646 females with mean age of 59.45±11.72. The overall prevalence of COPD was 13.60%. Male and female prevalence rates were 13.90% and 13.41%, respectively. Divided by age, the prevalence of the age of 40 to 50 was 3.38%, the age of 51 to 60 was 9.57%, the age of 61 to 70 was 19.15%, and the age of above 70 was 29.35%. The results of multivariate logistic regression analysis showed that the main risk factors of COPD were smoking, passive smoking, history of dust exposure, chronic respiratory disease history and age. Conclusion The total prevalence of COPD in Jiaxing area is high, and the female prevalence rate is especially higher than the national average level, which is the epidemiological characteristic of this area. Because the risk factors of COPD are complex, an integrated control strategy should be adopted.
