Abstract
ObjectiveTo investigate the epidemiological distribution characteristics and related risk factors of chronic obstructive pulmonary disease (COPD) in Fuzhou among people aged 40 years or older, and provide guidance for the prevention and treatment of COPD.
MethodsA random and cluster sampling method was used to survey people who older than 40 years in five districts of Fuzhou (Gulou District, Cangshan District, Jin′an District, Taijiang District and Mawei District). We designed a questionnaire for the respondents, after which, some physical examinations and lung function tests were carried out.COPD-related univariate and multivariate statistical analysis were performed on the data obtained.
ResultsWe validated 1 055 participants with available data.The overall prevalence of COPD was 10.6%(112/1 055). Male and female prevalence rates were 13.0% (70/538) and 8.1%(42/517). Age (χ2=27.051, P<0.01), gender (χ2=4.374, P<0.05), BMI (χ2=27.925, P<0.05), smoking (χ2=13.900, P<0.01), childhood cough history (χ2=80.580, P<0.01), family history (χ2=42.961, P<0.01), indoor fumes (χ2=13.603, P<0.01) and kitchen ventilation (χ2=12.111, P<0.05) were associated with the risk of COPD in the multivariate logistic regression analysis.
ConclusionsThe total prevalence of COPD among people aged ≥40 years in Fuzhou was 10.6%.The main factors affecting COPD are male, elder, lower BMI, smoking, coughing history, family history of respiratory disease, heavy indoor fumes and poor kitchen ventilation.The risk factors related to COPD involve multiple aspects of individual, family and social life.The prevention and treatment of COPD should be carried out in a targeted manner to reduce the prevalence of COPD and improve the quality of life of COPD patients.
