INTRODUCTION The aim of this study was to determine trends in receiving quit advice from healthcare professionals among current smokers in South Africa, pre- and post-adoption of Article 14 guidelines of the WHO FCTC in 2010, and to determine the association between quit advice, e-cigarette use and quit attempt. METHODS This study was a secondary data analysis involving 2206 ever-smokers aged ≥16 years who participated in the South African Social Attitude Surveys conducted in 2007, 2010 and 2017. Data included participants' sociodemographics, tobacco, and/or e-cigarette use (for years 2010 and 2017 only), exposure to others' smoking at home and/or work or public places, quit advice, and quit attempts. Analyses included chi-squared test and logistic regression. RESULTS The mean cigarettes smoked per day, the proportions of smokers offered quit advice, planning to quit and who made a quit attempt did not change significantly between 2007 and 2017 (p=0.67, p=0.70, p=0.09 and p=0.40, respectively). However, there was a marginally significant increase in e-cigarette uptake between 2010 and 2017 (p=0.05). In a bivariate analysis, quit advice was significantly associated with making a quit attempt across all survey years. In the final multivariable-adjusted regression model, having received a quit advice (OR=1.967; 95% CI: 1.255-3.083) compared to not, and being Colored/mixed race (OR=0.467; 95% CI: 0.298-0.732) compared to self-identifying as Black African, remained independently associated with making a quit attempt. CONCLUSIONS Except for marginally increased e-cigarette use, there was no significant change in smoking or quitting behavior in South Africa post-adoption of Article 14 guidelines. The study findings highlight the importance of quit advice in promoting quitting behavior and suggest the need to scale it up in South Africa.

南非的一项跨部门研究：2007年至2017年间南非的戒烟建议和戒烟尝试。

简介这项研究的目的是确定南非目前吸烟者从卫生保健专业人员那里获得戒烟建议的趋势，2010年世界卫生组织《烟草控制框架公约》第14条指南的采用前后，以及确定戒烟建议之间的关联，电子烟的使用并退出尝试。方法该研究是一项二级数据分析，涉及2206名≥16岁的长期吸烟者，他们参加了2007年，2010年和2017年进行的南非社会态度调查。数据包括参与者的社会人口统计学，烟草和/或电子烟使用情况（仅适用于2010年和2017年），在家里和/或工作场所或公共场所接触他人的烟，戒烟建议和戒烟尝试。分析包括卡方检验和逻辑回归。结果每天平均抽烟，在2007年至2017年之间，提供戒烟建议，计划戒烟和尝试戒烟的吸烟者比例没有显着变化（分别为p = 0.67，p = 0.70，p = 0.09和p = 0.40）。但是，2010年至2017年间，电子烟的摄入量略有增加（p = 0.05）。在双变量分析中，在所有调查年中，戒烟建议与进行戒烟尝试显着相关。在最终的多变量调整回归模型中，与否相比，收到戒烟建议（OR = 1.967; 95％CI：1.255-3.083），并且是有色/混合种族（OR = 0.467; 95％CI：0.298-0.732）与自我识别为“非洲黑人”的人相比，仍然保持与戒烟尝试的独立联系。结论除了略微增加了电子烟的使用量外，在采用第14条指南后，南非的吸烟或戒烟行为没有明显变化。该研究结果突出了戒烟建议对促进戒烟行为的重要性，并表明有必要在南非扩大戒烟行为。
