To track smokers' responses to the increasing price of cigarettes after a tax increase, and assess socio-demographic differences in responses.
The Cancer Institute NSW's Tobacco Tracking Survey (CITTS) is a continuous tracking telephone survey. Weekly data were collected between May and September 2010.
New South Wales, Australia.
A total of 834 smokers and 163 recent quitters (quit in last 12 months).
Responses to the price increase included smoking-related changes (tried to quit, cut down) and product-related changes (changed to lower priced brands, started using loose tobacco, bought in bulk). Recent quitters were asked how much the increasing price of cigarettes influenced them to quit.
Overall, 47.5% of smokers made smoking-related changes and 11.4% made product-related changes without making smoking-related changes. Multinomial logistic regressions showed that younger smokers (versus older) were more likely to make product-related changes and smoking-related changes in comparison to no changes. Low- or moderate-income smokers (versus high-income) were more likely to make smoking-related changes compared to no changes. Highly addicted smokers (versus low addicted) were more likely to make product-related changes and less likely to make smoking-related changes. The proportion of smokers making only product-related changes decreased with time, while smoking-related changes increased. Recent quitters who quit after the tax increase (versus before) were more likely to report that price influenced them.
The effect of increasing cigarette prices on smoking does not appear to be mitigated by using cheaper cigarette products or sources. These results support the use of higher cigarette prices to encourage smoking cessation.
追踪吸烟者对增税之后香烟价格上涨的反应，并评估不同社会人口学特征的反应差异。
新南威尔士癌症研究所的烟草追踪调查（CITTS）是一项连续的追踪电话调查。2010 年 5 月至 9 月期间每周收集数据。
澳大利亚新南威尔士州。
共有 834 名吸烟者和 163 名近期戒烟者（在过去 12 个月内戒烟）。
对价格上涨的反应包括与吸烟相关的变化（试图戒烟、减少吸烟量）和与产品相关的变化（改用价格较低的品牌、开始使用散装烟、大量购买）。最近戒烟者被问及香烟价格上涨对他们戒烟的影响有多大。
总体而言，47.5%的吸烟者进行了与吸烟相关的改变，11.4%进行了与产品相关的改变而没有进行与吸烟相关的改变。多项逻辑回归显示，与年龄较大的吸烟者相比，年龄较小的吸烟者更有可能进行产品相关的改变和与吸烟相关的改变，而不是不做任何改变。与高收入者相比，低收入或中等收入者更有可能进行与吸烟相关的改变，而不是不做任何改变。与低成瘾者相比，高成瘾者更有可能进行产品相关的改变，而不太可能进行与吸烟相关的改变。只进行产品相关改变的吸烟者比例随着时间的推移而减少，而与吸烟相关的改变则增加。在增税之后（而不是之前）戒烟的近期戒烟者更有可能报告价格对他们有影响。
使用更便宜的香烟产品或来源似乎并不能减轻香烟价格上涨对吸烟的影响。这些结果支持使用更高的香烟价格来鼓励戒烟。
