To understand the passive smoking exposure level and related risk awareness in adults in China in 2013. A face-to-face questionnaire survey was conducted in 179 570 adults selected through multistage cluster sampling from Chinese chronic disease and risk factors surveillance sample population (2013) in 302 surveillance sites. The effective sample size was 176 179 adults. After comprehensive weighting of the samples, the passive smoking exposure level and the awareness rate of related risks were analyzed. The passive smoking exposure rate was 52.8 (95: 51.2-54.4) and the rate decreased with age ((2)=515.8, <0.000 1). The exposure rate was highest in persons engaged in commercial services (61.6, 95: 58.6-64.5). The awareness rate of related risks was 67.9 (95: 65.8-69.9). The awareness rate was higher in urban area (77.0, 95: 75.0-79.1) than in rural area (60.0, 95: 57.7-62.4), in males (69.8, 95: 67.8-71.7) than in females (65.9, 95: 63.7-68.1). The awareness rate of three related diseases in urban residents (49.8, 95: 47.3-52.4) were higher than that in rural residents (37.9, 95: 35.4-40.5); the awareness rate of passive smoking related lung cancer was highest (88.5, 95: 87.5-89.5), followed by lung disease in children (70.0, 95: 68.1-71.9), the awareness rate of passive smoking related heart disease was lowest (46.8, 95: 44.6-49.1). The passive smoking exposure level is relatively high in adults in China, and the awareness rate of passive smoking exposure risks, especially heart disease, is low.
了解2013年中国成年人被动吸烟暴露水平及相关风险知晓情况。采用多阶段整群抽样方法，从中国慢性病与危险因素监测（2013年）样本人群的302个监测点中抽取179570名成年人进行面对面问卷调查。有效样本量为176179名成年人。对样本进行综合加权后，分析被动吸烟暴露水平及相关风险知晓率。被动吸烟暴露率为52.8（95%CI：51.2 - 54.4），且该率随年龄增长而降低（χ² = 515.8，P < 0.0001）。从事商业服务的人群暴露率最高（61.6，95%CI：58.6 - 64.5）。相关风险知晓率为67.9（95%CI：65.8 - 69.9）。城市地区知晓率（77.0，95%CI：75.0 - 79.1）高于农村地区（60.0，95%CI：57.7 - 62.4），男性知晓率（69.8，95%CI：67.8 - 71.7）高于女性（65.9，95%CI：63.7 - 68.1）。城市居民对三种相关疾病的知晓率（49.8，95%CI：47.3 - 52.4）高于农村居民（37.9，95%CI：35.4 - 40.5）；被动吸烟相关肺癌的知晓率最高（88.5，95%CI：87.5 - 89.5），其次是儿童肺部疾病（70.0，95%CI：68.1 - 71.9），被动吸烟相关心脏病的知晓率最低（46.8，95%CI：44.6 - 49.1）。中国成年人被动吸烟暴露水平较高，被动吸烟暴露风险知晓率，尤其是心脏病的知晓率较低。
