Note: Between the two surveys Thailand launched its first large-scale mass media anti-smoking campaign; while no campaign was introduced in Malaysia during this period.

Of those attempted in China, 21.7% were still stopped smoking at Wave 2, which is close to the maintenance rates in ITC-4 and ITC-SEA countries.

Quit attempt – PredictorsMultivariate analyses showed that independent predictors of making quit attempts

in Chinese smokers included:• Higher quitting self-efficacy; • Previous quit attempts;• Having at least some intentions to quit; • Lower dependence (longer time to first cigarette);• Having very negative opinion of smoking;• Having smoking restrictions at home• *(health concerns not predictive in China)

Notes: Underlined factors differ to ITC SEA countries. In China, some city to city variability.

Quit success – Predictors

Independent predictors of maintenance among those who made attempts included:

• Older age;

• Having long previous abstinence from smoking (>6 months);

• Having more immediate quitting intentions (ie, planning to quit within 1 month);

• Having some health concerns about smoking (not strong concerns);

• (dependence, self-efficacy NOT predictive in China)

Notes: Underlined factors differ to ITC SEA countries. In China, some city to city variability.

Some thoughts

• The cessation population may change over time

• Assistance only reaches a minority

• Those who need it may not want it early on

• Role of specialist clinics???

• Roles for Quitlines

• Rx access patchy– Access for poor???

• Potential of internet

• Knowledgeable health professionals
