Abstract:

Objective To investigate the prevalence and distribution characteristics of chronic obstructive pulmonary disease(COPD) in the adults aged 40 years and over in China,and to clarify the high risk population of COPD. Methods All published studies from PubMed,EMbase,VIP,CNKI,and Wanfang databases about COPD in Chinese or English were selected. According to the exclusion and inclusive criteria,the studies were selected,and the qualities of included studies were evaluated and the Meta-analysis was performed by Stata 12.0 software. Results A total of 49 studies were included in this study.The total number of participants investigated was 118 233,including 10 819 patients with COPD.The prevalence of COPD in the adults aged 40 years and over in China was 9.3%(95%CI:8.4%-10.1%). The prevalence of COPD in men(12.5%,95%CI:11.2%-13.8%) was higher than that in women (6.1%,95%CI:5.3-6.8).The older the age was,the higher the prevalence of COPD was.The higher the education was,the lower the prevalence of COPD was.In recent years,the prevalence of COPD was decreased.The prevalence of COPD in rural area(10.2%, 95% CI:9.3-11.2) was higher than that in urban area (7.9%, 95% CI:6.8-9.0).The prevalence of COPD of smokers (15.7%,95% CI:13.4-18.1) was higher than that of non smokers (5.4%,95% CI:4.5-6.3). For male,the highest prevalence showed in north China which was 15.8%(95%CI:10.9-20.7),while for women it was highest in northeast which was 6.9%(95%CI:5.0-8.9). Conclusion The prevalence of COPD in our country is still high. The prevalence is different among people with different characteristics.Male,higher age,low education level,smoking and rural population are high risk population of COPD.
