The impact of point-of-sale anti-smoking advertising on adult smokers’ quitting intentions and behaviours: Findings from the ITC China Survey
*First I would like to thank the Scientific Program Committee and the sponsors for providing me the opportunity to share my research at this important congress.
*The title of my presentation today is
*There are two learning objectives:
To examine prospective predictors of smoking cessation among adult smokers in the Chinese context.
To understand the predictors of making quit attempts and successful quitting among adult smokers in different socio-economic and cultural contexts.

2. Aim and Methods
Aim: To examine the association between exposure to anti-smoking advertising at the point of sale (POS) and smokers' quitting intentions and behaviours.
Methods: ITC China Survey is a prospective face-to-face cohort survey
Stratified multi-stage cluster sampling design
Participants were from Beijing and other 5 cities
In mid 2006, 4,732 adult smokers were first surveyed. Of these, 3,863 were successfully followed up in the second Wave in late 2007, with a 16 months inter-survey interval and a retention rate of 82%.
Baseline measures of exposure to POS anti-smoking information, dependence and sociodemographics were used prospectively to predict smokers' intentions to quit and making quit attempts. Logistic regression modelling was employed.

3. Key results
Overall, 964 out of the 3863 (25%) smokers reported having intentions to quit at Wave 2 of the survey.
After adjustment for demographics and dependence, smokers who reported being exposed to anti-smoking information in stores where they bought tobacco were more likely to have intentions to quit than those who were not exposed (30.7% vs 25.7%, adjusted odds ratio=1.27, 95%CI: , p<0.05).
A marginally higher proportion of smokers who had noticed anti-smoking information around street vendors made quit attempts between Waves than did those had not noticed (28.9% vs 25.1%), but the differences were not significant either in univariate or multivariate analyses.
Those smokers with higher levels of nicotine dependence were less likely to have intentions to quit and have made quit attempts between Waves.

4. Conclusions
The results indicate there is a positive association between smokers’ exposure to anti-smoking information in stores and their intentions to quit.
Given the sheer size of smokers in China, more comprehensive POS anti-smoking interventions are needed to encourage people to quit, and continuous evaluation of the impacts of such interventions is vital.
