This study assessed cessation and brand switching among smokers in Ontario, Canada after tobacco companies' voluntary removal of 'light' and 'mild' descriptors from cigarette packages.
We analyzed longitudinal data on brand preference and cessation from a cohort of smokers (n=632) in the Ontario Tobacco Survey in Canada from 2006 to 2008 with a longitudinal regression model.
While cessation differed by brand variant prior to the ban (7% light vs. 3% regular; P<0.05), it did not differ by brand variant after the ban was implemented. In 2008, when light cigarette brand variants were no longer available, 33% of the sample still reported smoking lights and 31% smoked light replacement brand variants. During each subsequent follow-up, light brand smokers had 2 times the odds of smoking regular brand variants (Adjusted OR: 2.03, 95% CI 1.80,2.29), and almost 5 times the odds of using light replacement brand variants (Adjusted OR: 4.87, 95% CI 4.07,5.84), respectively, compared to continuing to smoke lights.
Even after removing misleading descriptors from cigarette packs, smokers continued to report using light brand variants, and many switched to newly introduced light replacement brand variants. After full implementation of the ban, cessation did not vary by brand variant.
本研究评估了在加拿大安大略省,烟草公司自愿从香烟包装上移除“淡味”和“轻度”描述词后,吸烟者的戒烟情况和品牌转换情况。
我们使用纵向回归模型,分析了2006年至2008年加拿大安大略烟草调查中一组吸烟者(n = 632)的品牌偏好和戒烟情况的纵向数据。
在禁令实施前,不同品牌变体的戒烟情况有所不同(淡味烟为7%,普通烟为3%;P<0.05),但禁令实施后,不同品牌变体的戒烟情况没有差异。2008年,当淡味香烟品牌变体不再供应时,33%的样本仍报告吸食淡味烟,31%的样本吸食淡味烟替代品牌变体。在随后的每次随访中,与继续吸食淡味烟相比,吸食淡味烟品牌的吸烟者吸食普通品牌变体的几率分别高出2倍(调整后的比值比:2.03,95%置信区间1.80,2.29),吸食淡味烟替代品牌变体的几率高出近5倍(调整后的比值比:4.87,95%置信区间4.07,5.84)。
即使从香烟包装上移除了误导性描述词,吸烟者仍继续报告使用淡味烟品牌变体,许多人转而使用新推出的淡味烟替代品牌变体。禁令全面实施后,不同品牌变体的戒烟情况没有差异。
