ABSTRACT

Objective To investigate current status of cognitive behavior on chronic obstructive pulmonary disease (COPD) to provide evidence for targeted intervention.Methods A questionnaire survey on COPD was conducted at 12 settings of 4 prefectures that were sampled from Ningxia Province using multistage stratified cluster random sampling method,and 4268 residents at least 40 years old were interviewed.Multivariate linear regression method was used for data analysis.Results A total of 4056 valid questionnaires were returned from 4200 participants with an effective response rate of 96.57％.Only 6.51％(264/4056) had an idea of COPD,13.88％ (563/4056) regarded cigarette smoking as a risk factor of chronic bronchitis and emphysema,and 6.39％ (259/4056) knew pulmonary function tests.Home income,living area,education level and ethnicity were main factors influencing COPD awareness.The percentage of current cigarette smoking was 28.80％ (1168/4056) with 20.40％ in Hui (Muslim) ethnic group and 34.63％ in Han ethnic group (P ＜ 0.05 ) ; smoking index and severe smokers were not significantly different between the two groups ( P ＞ 0.05 ).Conclusion Our data suggest a considerably poor knowledge and prevention awareness of COPD in Ningxia Province.In spite of relatively lower cigarette smoking rate,the problem that Hui (Muslim) ethnic people are lack of COPD awareness should not to be neglected.
