Smoking cessation advice and quit attempts in South Africa between 2007 and 2017: A cross-sectional study.

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.
