Retracted: Prevalence of residents with chronic obstructive pulmonary disease and risk factor analysis in Dongguan Shi long region in Guangdong Province
Purpose: To investigate the prevalence of residents with Chronic Obstructive Pulmonary Disease (COPD) and related risk factors in the Dongguan Shi long region of Guangdong Province, China.
Method: Random samples of patients more than 40 y of age with high-risk COPD from the region underwent pulmonary function testing and completed a questionnaire survey to determine the prevalence of COPD. Then, single and multiple factor logistic analysis was carried out on the influencing factors.
Results: The overall COPD prevalence in this region was 9.05%; the prevalence for males was higher than females. With aging, the prevalence of COPD increased significantly (P<0.05). COPD was mainly grades I and II. The differences between COPD patients and non-COPD patients pertaining to gender, age, education level, Body Mass Index (BMI), a family history of respiratory disease, and Smoking Index (SI) were significant (P<0.05). Logistic multi-factor regression analysis showed that BMI, age, gender, and SI were risk factors for COPD prevalence (P<0.05 or P≈0.05).
Conclusion: The prevalence of COPD in this region was higher, and BMI (higher), age (elder), gender (male), and SI (higher) were shown to be risk factors. Therefore, active intervention for these risk factors should be offered to reduce the COPD prevalence in this region.Author(s): Lei Wu, Meihua Chen, Taorong Xu, Yanling Cai
