To understand the awareness of knowledge about COPD and related factors in residents aged ≥40 years in China. Through multi-stage stratified cluster sampling, residents aged ≥40 years were selected from 125 sites of COPD surveillance (2014-2015) in 31 provinces of China for a face to face questionnaire survey. The demographic characteristics and awareness rate of knowledge about COPD among 75 082 subjects were described as frequency and percentage. The awareness rate of knowledge about COPD and its 95 confidence interval () among the residents aged ≥40 years were estimated with complicated sampling weights. Meanwhile, the knowledge awareness related factors were screened in complicated sampling data. The awareness rate of COPD was 9.2. The awareness rate of pulmonary function test was 3.6 and the awareness rate of COPD-related knowledge was 5.8. All of the awareness rates were associated with gender, age, education level and occupation. Besides, the awareness rate of pulmonary function test and COPD-related knowledge were related with living area. Compared with females, the s of the three awareness rates among males were 0.88, 0.81 and 0.78. Compared with the residents aged ≥70 years, the s of the three awareness rates among those aged 60-69 years were 1.28, 1.08 and 1.51. Compared with the residents with education level of primary school or below, the s of the three awareness rates among those with college degree or above were 2.28, 3.43 and 3.14. The of the awareness rate of pulmonary function test among the residents in the eastern area was 1.77 compared with those in the central area. The s of the awareness rate of COPD-related knowledge among the residents in the eastern and western areas were 1.95 and 2.16 compared with those in the central area(all above <0.05). Among COPD symptoms, the awareness rate of dyspnea was highest (67.9), and among the risk factors for COPD, the awareness rate of smoking was highest (81.3). The source of awareness of COPD for most residents was television program (38.2). The awareness rate of knowledge about COPD was low in residents aged ≥40 years in China in 2014. It is necessary to strengthen the health education about COPD to improve the prevention and control of the disease.
了解中国40岁及以上居民对慢性阻塞性肺疾病（COPD）的知晓情况及相关因素。通过多阶段分层整群抽样，从中国31个省份125个COPD监测点（2014 - 2015年）选取40岁及以上居民进行面对面问卷调查。描述75082名研究对象的人口学特征及COPD知识知晓率，以频数和百分比表示。采用复杂抽样权重估计40岁及以上居民COPD知识知晓率及其95%置信区间（CI）。同时，在复杂抽样数据中筛选知识知晓相关因素。COPD知晓率为9.2%。肺功能检查知晓率为3.6%，COPD相关知识知晓率为5.8%。所有知晓率均与性别、年龄、教育程度和职业有关。此外，肺功能检查和COPD相关知识知晓率与居住地区有关。与女性相比，男性三项知晓率的比值比（OR）分别为0.88、0.81和0.78。与70岁及以上居民相比，60 - 69岁居民三项知晓率的OR分别为1.28、1.08和1.51。与小学及以下文化程度居民相比，大专及以上文化程度居民三项知晓率的OR分别为2.28、3.43和3.14。东部地区居民肺功能检查知晓率与中部地区相比的OR为1.77。东部和西部地区居民COPD相关知识知晓率与中部地区相比的OR分别为1.95和2.16（均P<0.05）。在COPD症状中，呼吸困难知晓率最高（67.9%），在COPD危险因素中，吸烟知晓率最高（81.3%）。大多数居民COPD知晓来源为电视节目（38.2%）。2014年中国40岁及以上居民COPD知识知晓率较低。有必要加强COPD健康教育以改善疾病的预防和控制。
