Abstract
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.
期刊介绍：
Tobacco Control is an international peer-reviewed journal covering the nature and consequences of tobacco use worldwide; tobacco''s effects on population health, the economy, the environment, and society; efforts to prevent and control the global tobacco epidemic through population-level education and policy changes; the ethical dimensions of tobacco control policies; and the activities of the tobacco industry and its allies.
