背景在澳大利亚实施带有较大图形健康警告（GHW）的烟草素包装（PP）对反映PP政策具体目标的响应以及后续戒烟相关认知和行为产生了积极影响。本研究的目的是检查这些近端和远端outcome.Methods的澳大利亚成年吸烟者的全国代表性样本之间的预测关系完成了基线调查和1个月的随访调查，在第一年的政策实施（n（加权）=3125）。Logistic回归分析测试了香烟吸引力，GHW有效性，感知伤害和关注/享受的基线测量是否预测戒烟相关认知和行为的七个后续测量中的每一个，调整结果和协变量的基线水平。我们发现一致的证据表明，GHW有效性的几个基线测量积极和显着预测吸烟者在遵循-up报告说，至少每天都在考虑戒烟，打算戒烟，有一个确切的戒烟日期，过早地戒烟，停止吸烟，并试图戒烟。两个戒烟相关的结果也预测了更多的吸烟相关的关注比享受。一个较小的数量的上诉变量与戒烟相关的结果是前瞻性的，而相信品牌没有不同的危害性没有积极预测任何outcome.Conclusions这些研究结果提供了一个初步的洞察，通过PP与较大的GHW可能会导致吸烟行为的变化的途径。未来的研究应该检查这种影响是否取决于个人的人口统计学和吸烟特征。
Background Implementation of tobacco plain packaging (PP) with larger graphic health warnings (GHWs) in Australia had positive effects on responses reflecting the specific objectives of the PP policy and on follow-up quitting-related cognitions and behaviours. The aim of this study was to examine predictive relationships between these proximal and distal outcomes.Methods A nationally representative sample of Australian adult cigarette smokers completed a baseline survey and a 1-month follow-up survey within the first year of policy implementation (n(weighted)=3125). Logistic regression analyses tested whether baseline measures of cigarette appeal, GHW effectiveness, perceived harm and concern/enjoyment predicted each of seven follow-up measures of quitting-related cognitions and behaviours, adjusting for baseline levels of the outcome and covariates.Results In multivariable models, we found consistent evidence that several baseline measures of GHW effectiveness positively and significantly predicted the likelihood that smokers at follow-up reported thinking about quitting at least daily, intending to quit, having a firm date to quit, stubbing out cigarettes prematurely, stopping oneself from smoking and having attempted to quit. Two of the quitting-related outcomes were also predicted by feeling more smoking-related concern than enjoyment. A smaller number of the appeal variables were prospectively associated with quitting-related outcomes, while believing that brands do not differ in harmfulness did not positively predict any outcomes.Conclusions These findings provide an initial insight into the pathways through which PP with larger GHWs may lead to changes in smoking behaviour. Future research should examine whether the effects are conditional on individual demographic and smoking characteristics.
