摘要
目的：我们研究了澳大利亚从 2007 年到 2020 年期间烟草税的增加和购买烟草时使用成本最小化行为（CMB）与（1）烟草支出和（2）戒烟尝试和戒烟成功之间的关系：(1) 烟草支出和 (2) 戒烟尝试和戒烟成功率：我们使用了国际烟草控制政策评估项目澳大利亚调查（样本数=4975，观察数=10 474）九次波次（2007-2020）中收集的吸工厂制造和/或卷烟（RYO）的成年人的数据。CMB包括购买RYO烟草、纸盒、大包装、经济装，或避税/逃税、减少吸烟和使用电子烟。利用广义估计方程拟合的逻辑回归估算了CMB与戒烟尝试和下一轮随访时的戒烟成功率之间的关系（Nsubsample=2984，Nobservations=6843）：超过一半的受访者在基线（2007-2008 年为 57.1%）时使用中巴购买烟草（P-中巴），税率提高后增加到 76.8%（2018 年）。参与任何私营中巴都与每周烟草支出较高有关。参与任何私营中巴与尝试戒烟呈负相关（aOR=0.82，95% CI 0.69-0.98）。购买 RYO 烟草或烟盒与未尝试戒烟有关（aOR=0.66，95% CI 0.52-0.83；aOR=0.72，95% CI 0.59-0.89）。在尝试戒烟的吸烟受访者中，所有 P-CMB 与戒烟成功率之间均无显著关联。减少吸烟量和吸食电子烟均与戒烟尝试无明显关系：结论：颗粒状中巴与戒烟率降低有关。减少烟草行业推广与购买相关的中巴选项的机会，例如通过标准化包装尺寸和减少零售卷烟与制造卷烟之间的价格差异，可以提高增税的效果。
The impact of tobacco tax increases on cost-minimising behaviours and subsequent smoking cessation in Australia: an analysis of the International Tobacco Control Policy Evaluation Project.
Objective: We examined the relationship in Australia from 2007 to 2020 between tobacco tax increases and use of cost-minimising behaviours (CMBs) when purchasing tobacco and: (1) tobacco expenditure and (2) smoking cessation attempts and quit success.
Methods: We used data collected from adults who smoked factory-made and/or roll-your-own (RYO) cigarettes in nine waves (2007-2020) of the International Tobacco Control Policy Evaluation Project Australia Survey (Nsample=4975, Nobservations=10 474). CMBs included buying RYO tobacco, cartons, large-sized packs, economy packs, or tax avoidance/evasion, smoking reduction and e-cigarette use. Logistic regression, fit using generalised estimating equations, estimated the CMB-outcome association for quit attempts and quit success at the next wave follow-up (Nsubsample=2984, Nobservations=6843).
Results: Over half of respondents used a CMB for tobacco purchase (P-CMB) at baseline (57.1% in 2007-2008), increasing to 76.8% (2018) post-tax increases. Participating in any P-CMB was associated with having higher weekly tobacco expenditure. Engaging in any P-CMB was negatively associated with attempting to quit (aOR=0.82, 95% CI 0.69-0.98). Purchasing RYO tobacco or cartons was associated with making no quit attempts (aOR=0.66, 95% CI 0.52-0.83; aOR=0.72, 95% CI 0.59-0.89, respectively). Among respondents smoking cigarettes who made quit attempts, there were no significant associations between all P-CMBs and quit success. Neither smoking reduction nor vaping were significantly associated with quit attempts.
Conclusion: P-CMBs are associated with reduced smoking cessation. Reducing opportunities for industry to promote purchasing-related CMB options, such as by standardising pack sizes and reducing the price differential between RYO and manufactured cigarettes could increase the effectiveness of tax increases.
