To describe the regional and demographic differences on passive non-smokers from 10 regions involved in the China Kadoorie Biobank (CKB) study. Detailed information regarding passive smoking behaviors related to 317 486 non-smokers who were 30-79 years old from the 10 study regions were gathered and analyzed. Following the standardization of the 2010 China national population, the prevalence rate of passive smoking was 56.7, and the prevalence rate of living with smokers was 66.5 among the Chinese adults. Both of the aforementioned rates were higher in rural than in urban areas. Meanwhile, the regional distribution of weekly passive smoking frequency and cumulative duration of passive smoking per week and cumulative duration of passive smoking per day were significantly different. The cumulative passive smoking duration per week increased along with the weekly frequency in people living in urban areas. Among women, the weekly passive smoking frequency was the highest, and the cumulative durations per week and per day appeared the lowest in Hunan, opposite to the situation in Henan. The prevalence of passive smoking among participants living with smokers was 2.27 times (95: 2.242.29) of those who were not and the association appeared stronger in women (=2.61, 95: 2.58-2.64) but not in men (=1.01, 95: 0.95-1.06). Almost all the indicators seemed higher in women than those in men, except for the cumulative duration per day. Furthermore, these indicators appeared higher among those who were at younger age or with less education. The prevalence rates of passive smoking and living with smokers were lower but the cumulative duration per day was higher among those with lower household income. And the two rates were higher in married women and lower in married men, as compared to their counterparts. Regional and demographic differences in passive smoking were noticed among study population of CKB in the 10 regions.
描述参与中国嘉道理生物样本库（CKB）研究的10个地区被动不吸烟者的地区和人口统计学差异。收集并分析了来自10个研究地区的317486名30 - 79岁非吸烟者与被动吸烟行为相关的详细信息。按照2010年中国全国人口标准化后，中国成年人中被动吸烟患病率为56.7%，与吸烟者共同生活的患病率为66.5%。上述两个比率农村地区均高于城市地区。同时，每周被动吸烟频率、每周被动吸烟累计时长以及每天被动吸烟累计时长的地区分布存在显著差异。城市地区人群每周被动吸烟累计时长随每周频率增加而增加。在女性中，湖南的每周被动吸烟频率最高，每周和每天的累计时长最短，与河南的情况相反。与非吸烟者共同生活的参与者中被动吸烟患病率是未与吸烟者共同生活者的2.27倍（95%置信区间：2.24 - 2.29），且该关联在女性中更强（比值比 = 2.61，95%置信区间：2.58 - 2.64），在男性中则不显著（比值比 = 1.01，95%置信区间：0.95 - 1.06）。除每天累计时长外，几乎所有指标女性均高于男性。此外，这些指标在年龄较小或受教育程度较低者中更高。家庭收入较低者被动吸烟患病率和与吸烟者共同生活的患病率较低，但每天累计时长较高。与相应的未婚者相比，已婚女性中这两个比率较高，已婚男性中较低。在CKB研究的10个地区的研究人群中，注意到了被动吸烟的地区和人口统计学差异。
