The availability of cigarettes from cheaper sources constitutes a major challenge to public health throughout the world, including China, because it may counteract price-based tobacco control policies. The goal of this study was to identify factors associated with purchasing cigarettes from cheaper sources among adult smokers in China.
Data were analysed from Waves 1 to 3 of the International Tobacco Control China Survey conducted in 2006-2009 among adult smokers in six cities in China (N=7980). One survey question asked, "In the last 6 months, have you purchased cheaper cigarettes than you can get from local stores for economic reasons?" We examined whether sociodemographic factors and smoking intensity were associated with purchasing cigarettes from cheaper sources using the general estimating equations model. Sociodemographic factors considered were gender, age, marital status, monthly household income, education, employment status and city of residence.
15.6% of smokers reported purchasing cigarettes from cheaper sources. After controlling for other covariates, the associations of the behaviour of purchasing cigarettes from cheaper sources with age (adjusted OR (AOR)=1.49, 95% CI 1.17 to 3.92 for age 18-24 compared with age 55+) and with income (AOR=2.93, 95% CI 2.27 to 3.79 for low income compared with high income) were statistically significant, but there was no statistically significant relationship with smoking intensity.
Our findings indicate that young and low-income smokers are more likely than older and high-income smokers to purchase cigarettes from cheaper sources in China. Tobacco control policies that reduce the availability of cigarettes from cheaper sources could have an impact on reducing cigarette consumption among young and low-income smokers in China.
从更便宜渠道获取香烟对包括中国在内的全球公共卫生构成重大挑战，因为这可能会抵消基于价格的烟草控制政策。本研究的目的是确定中国成年吸烟者中与从更便宜渠道购买香烟相关的因素。
对2006 - 2009年在中国六个城市对成年吸烟者进行的国际烟草控制中国调查第1至3轮的数据进行分析（N = 7980）。一个调查问题是：“在过去6个月里，你是否因为经济原因购买过比从当地商店能买到的更便宜的香烟？”我们使用广义估计方程模型研究社会人口统计学因素和吸烟强度是否与从更便宜渠道购买香烟有关。考虑的社会人口统计学因素包括性别、年龄、婚姻状况、家庭月收入、教育程度、就业状况和居住城市。
15.6%的吸烟者报告从更便宜渠道购买香烟。在控制其他协变量后，从更便宜渠道购买香烟的行为与年龄（18 - 24岁与55岁及以上相比，调整后的比值比（AOR）= 1.49，95%置信区间为1.17至3.92）和收入（低收入与高收入相比，AOR = 2.93，95%置信区间为2.27至3.79）之间的关联具有统计学意义，但与吸烟强度没有统计学显著关系。
我们的研究结果表明，在中国，年轻和低收入吸烟者比年长和高收入吸烟者更有可能从更便宜渠道购买香烟。减少从更便宜渠道获取香烟的烟草控制政策可能会对减少中国年轻和低收入吸烟者的香烟消费产生影响。
