目的了解我国居民二手烟暴露程度，并探讨其影响因素。方法本研究是一项具有全国代表性的家庭调查，采用全球标准化地理聚类样本设计，研究15岁及以上非机构化男性和女性的二手烟暴露。共有13354人完成了个人问卷，问题包括性别、年龄、教育程度、居住地、职业、与二手烟暴露相关的潜在因素以及工作场所吸烟政策。这些数据被用来确定整个人口的二手烟暴露估计。在15岁及以上的非吸烟者中，估计有72.4%（5.56亿）暴露于二手烟，其中52.5%（2.92亿）每天暴露于二手烟。男性二手烟暴露率为74.1%，女性为71.6%，城市人口为70.5%，农村人口为74.2%。在家庭、室内工作场所和公共场所的感染率分别为67.3%、63.3%和72.7%。在禁烟的工作场所，二手烟暴露显着减少，但在部分禁烟的工作场所则没有。结论虽然中国在无烟环境方面取得了一定的进展，但二手烟暴露程度仍然很高。
Objective To determine the extent of secondhand smoke exposure in China, and to explore the potential associated factors. Methods This study was a nationally representative household survey examining secondhand smoke exposure of non-institutionalized men and women aged 15 and older using a global standardized geographically clustered sample design. A total of 13 354 people completed the individual questionnaire with questions on gender, age, educational level, residence, profession, potential factors associated with secondhand smoke exposure, and workplace smoking policy. The data were used to determine whole population estimates of secondhand smoke exposure. Results Among non-smokers aged 15 years and older, it was estimated that 72.4% (556 million) were exposed to secondhand smoke, with 52.5% (292 million) exposed to secondhand smoke daily. The prevalence of secondhand smoke exposure was 74.1% for men, 71.6% for women, 70.5% for urban populations, and 74.2% for rural populations. The rates were 67.3%, 63.3%, and 72.7% respectively, within the household, indoor workplaces and public places. Secondhand smoke exposure was significantly reduced in workplaces with a smoking ban but not in workplaces with a partial smoking ban. Conclusion Although China has made some progress toward a smoke-free environment there remains a high degree of exposure to secondhand smoke.
