Leveraging process models of self-regulation to understand self-quitting in Scotland

烟草是一个全球性的公共卫生问题，在苏格兰尤为普遍。目前，19%的苏格兰成年人口吸烟，在最贫困的社区中增加到32%。这种流行率转化为每年近10，000例与吸烟有关的死亡3，全社会的经济成本约为11亿英镑4。仅苏格兰NHS就可以从减少吸烟1%中节省约1340万英镑/年5。鉴于烟草造成的巨大危害，苏格兰政府的目标是到20346年将吸烟率降至5%，大多数吸烟者（超过70%）都有戒烟的雄心。然而，自2013年以来，吸烟率一直保持不变，最贫困群体的吸烟率略有上升。吸烟的持续性表明需要增加对成功戒烟的理解。

Tobacco is a global public health problem, with a particular prevalence in Scotland. 19% of the Scottish adult population currently smoke, increasing to 32% among the most deprived communities1,2. This prevalence translates into almost 10,000 smoking-related deaths per year3, and a society-wide economic cost of approximately £1.1 billion4. NHS Scotland alone would save ~£13.4 million/year from a 1% reduction in smoking5. Given the considerable harm caused by tobacco, the Scottish Government aims to reduce smoking rates to 5% by 20346, and the majority of smokers-over 70%-share the ambition to quit1. However, smoking rates have been static since 2013, with slight increases among the most deprived groups1. This persistence of smoking indicates a need for increased understanding of successful smoking cessation.
