Modelling the Effects of Integrating Key Tobacco Control Policies with Health Provider Advice on Quit Attempts Among South Africans ‘Lekan Ayo-Yusuf , BDS, MPH, PhD Dept of Community Dentistry & School of Health Systems & Public Health 1

Background • The guidelines to Article 14 of the WHO FCTC encourages the promotion of cessation through the implementation of other demand reduction measures in the FCTC. • Yet, only limited empirical data is available on the mechanism linking these key policy interventions to one another with regards their contributions to promoting quit attempts. • This study therefore sought to quantify the relative effects of three policy interventions namely health provider advice, pricing policy and workplace smoking ban on quit attempt among a nationally representative sample of South African Adult smokers (n= 688).

Methods • The a priori model was specified based on the theory of planned behaviour and tested to see how well it fits our data using SEM (AMOS 19.0). • Model was adjusted by removing non-significant pathways (bootstrap standardized estimates) and modified further based on inspection of modification indices. • Adequacy of model fit – chi-square statistics (>0.05), Normed Fit Index (NFI) and Goodness of fit Index (GFI) of >0.9 and RMSEA ≤ 0.08.

Results & Conclusions: • 58.8% reported having made recent quit attempt, but only 25% reported having ever been advised by a health provider to quit. • Health concerns (59.7%) and high cost of cigarettes (47.6%) were cited as the most common reasons for wanting to quit.
