Abstract:
Objective To understand the prevalence of chronic obstructive pulmonary disease (COPD) among the community population aged ≥40 years in China from 1990 to 2014.Methods The studies on the prevalence of COPD among the community population in China published from 1990 to 2014 were retrieved from the following databases:Chinese BioMedical Literature Database (CBM),Chinese Journal Full-text Database (CNKI),Wanfang Database,PubMed and EBSCO.Mantel-Haenszel fixed effect and random effect model and software Stata were used for statistical analysis.Results A total 30 studies were included in the Meta analysis.The pooled prevalence of COPD was 9.9％ (95％ CI:8.8％-11.0％).The prevalence was higher in males (13.0％,95％ CI:11.5％-14.4％) than in females (5.8％,95％CI:4.9％-6.6％),and the prevalence of COPD increased with age obviously from 3.2％ in age group 40-49 years (95％ CI:2.5％-3.9％) to 20.3％ in age group ≥70 years (95％CI:18.2％-22.4％).The differences in prevalence among different areas had no statistical significance.Conclusions The prevalence of COPD in population aged ≥40 years increased gradually in China in recent 20 years.Obvious heterogeneity was found among the results of the studies due to the different diagnostic standards and sample sizes.
