The recent development of smoking cessation interventions for smokers with chronic diseases has focused heavily on brief interventions. However, these interventions are too brief to make an impact on these smokers, especially when most of them are without any intention to quit. Previous studies showed that smokers who did not want to quit might be interested in changing other health behaviours. Also, once people engage in a health behaviour, they are found more likely to change other unhealthy habits. Hence, a general health promotion approach could be a feasible approach to motivate smokers who do not want to quit to first engage in any desirable health behaviour, and later quit smoking when they intend to do so. This study aims to determine the potential efficacy and effect size of such intervention approach in promoting smoking cessation for smokers with chronic diseases.
This is a randomized controlled trial. A convenience sample of 60 smokers with chronic diseases will be randomly assigned into either experimental (n = 30) or control group (n = 30). Smokers in the experimental group will receive an individual face-to-face brief motivational interviewing (MI) with generic advice on selected health behaviour. More brief MI messages will be delivered to them via WhatsApp/WeChat for 6 months. For subject in the control group, they will be asked to indicate their desirable health-related practice. However, no MI and booster interventions will be given. All subjects will complete a questionnaire at 1, 3, 6 and 12 months. Subjects abstinent from cigarettes at 12 months will perform a biochemical validation. The primary outcome is biochemically validated smoking abstinence at 12 months. Effect size of the intervention will be estimated by the odd ratios using intention-to-treat.
This is the first study to determine the potential efficacy for the use of a personalized general health promotion approach in promoting smoking cessation for smokers with chronic diseases. If our proposed intervention is effective, we will able to assist smokers with chronic disease to quit smoking and change their health behaviour simultaneously.

最近针对患有慢性病的吸烟者的戒烟干预措施的发展重点主要放在简短干预上。然而，这些干预措施过于简短，无法对这些吸烟者产生影响，尤其是当他们大多数人都没有戒烟的意愿时。先前的研究表明，不想戒烟的吸烟者可能对改变其他健康行为感兴趣。此外，一旦人们开始进行健康行为，他们就更有可能改变其他不健康的习惯。因此，一般的健康促进方法可能是一种可行的方法，可以激励那些不想戒烟的吸烟者首先参与任何理想的健康行为，然后在他们打算戒烟时戒烟。本研究旨在确定这种干预方法在促进患有慢性病的吸烟者戒烟方面的潜在效果和效果大小。
这是一项随机对照试验。将 60 名患有慢性病的吸烟者作为方便样本，随机分为实验组（n=30）和对照组（n=30）。实验组的吸烟者将接受一次面对面的简短动机访谈（MI），并获得关于选定健康行为的一般性建议。在接下来的 6 个月里，他们将通过 WhatsApp/WeChat 收到更多的简短 MI 信息。对于对照组的受试者，他们将被要求指出他们期望的与健康相关的做法。但是，不会提供 MI 和助推器干预措施。所有受试者将在 1、3、6 和 12 个月时完成一份问卷。在 12 个月时戒烟的受试者将进行生化验证。主要结局是 12 个月时通过生化验证的吸烟戒断。采用意向治疗法估计干预的效应大小。
这是第一项确定个性化一般健康促进方法在促进患有慢性病的吸烟者戒烟方面的潜在效果的研究。如果我们提出的干预措施有效，我们将能够帮助患有慢性病的吸烟者戒烟并同时改变他们的健康行为。
