Point-of-sale tobacco marketing has been shown to be related to tobacco use behaviours; however, specific influences of cigarette price discounts, price tiers and pack/carton availability on cigarette purchasing intention are less understood by the tobacco control community.
We conducted discrete choice experiments among an online sample of US young adult smokers (aged 18-30 years; n=1823). Participants were presented scenarios depicting their presence at a tobacco retail outlet with varying availability of cigarette price discounts, price tiers and pack/carton. At each scenario, participants were asked whether they would purchase cigarettes. Generalised linear regression models were used to examine the associations between of cigarette price discounts, price tiers and pack/carton with intention to purchase cigarettes overall and stratified by educational attainment.
Participants chose to purchase cigarettes in 70.9% of the scenarios. Offering price discounts were associated with higher odds of choosing to purchase cigarettes. Reducing the number of cigarette price tiers available in the store was associated with lower odds of choosing to purchase cigarettes. Stratified analysis showed that offering discounts on high-tier cigarette packs increased odds of choosing to purchase cigarettes among young adult smokers with at least some college education, while offering discounts on medium-tier cigarette packs increased odds of choosing to purchase cigarettes among those with some college education or less (eg, with a 10% discount, adjusted odds ratio [AOR]=1.62, 95% confidence interval [CI] 1.21 to 2.16; AOR=1.44, 95% CI 1.08 to 1.93).
Availability of cigarette price discounts, price tiers and pack/carton could potentially influence cigarette purchasing behaviours among young adult smokers. Regulating these marketing strategies may, therefore, reduce education-related smoking disparities.
销售点烟草营销已被证明与烟草使用行为有关;然而,烟草控制界对香烟价格折扣、价格档次和包装/纸箱供应对购买香烟的意图的具体影响了解较少。
我们在一项美国年轻成年吸烟者(年龄在 18-30 岁之间;n=1823)的在线样本中进行了离散选择实验。参与者被呈现出不同价格折扣、价格档次和包装/纸箱供应情况下的烟草零售点场景。在每个场景中,参与者被问及是否会购买香烟。使用广义线性回归模型来研究香烟价格折扣、价格档次和包装/纸箱与总体购买香烟的意图以及按教育程度分层的意图之间的关联。
70.9%的参与者选择在场景中购买香烟。提供价格折扣与选择购买香烟的可能性更高相关。减少商店中可用的香烟价格档次数量与选择购买香烟的可能性降低相关。分层分析表明,在至少接受过一些大学教育的年轻成年吸烟者中,提供高档香烟包装的折扣会增加选择购买香烟的可能性,而在接受过一些大学教育或更少教育的吸烟者中,提供中档香烟包装的折扣会增加选择购买香烟的可能性(例如,10%的折扣,调整后的优势比[OR]=1.62,95%置信区间[CI]为 1.21 至 2.16;OR=1.44,95%CI 为 1.08 至 1.93)。
香烟价格折扣、价格档次和包装/纸箱的供应情况可能会影响年轻成年吸烟者的香烟购买行为。因此,监管这些营销策略可能会减少与教育相关的吸烟差异。
