Objective To investigate the prevalence and influencing factors of chronic obstructive pulmonary disease (COPD) among middle-aged and elderly residents in Fujian province and to provide evidences for prevention and control of the disease.
Methods We selected 2 170 permanent residents aged ≥ 40 years in two urban districts and two rural counties in Fujian province using stratified multistage random cluster sampling. Then we conducted a face-to-face questionnaire survey, physical examination, and lung function test among the participants from September to December 2015. The prevalence rate of COPD was estimated by complicated sampling weights and its influencing factors were analyzed with multivariate logistic regression model.
Results The estimated prevalence rate of COPD was 17.4% for the middle-aged and elderly residents. Multivariate logistic regression analysis indicated that older than 50 years, living in rural regions, smoking, exposure to occupational dust, history of hospitalization for serious respiratory infection during childhood were the risk factors for COPD among the population.
Conclusion The prevalence of COPD is relatively high and influenced by age, residential area, smoking, exposure to occupational dust and history of hospitalization for serious respiratory infection during childhood among middle-aged and elderly population in Fujian province.
