Objective: China took part in the fifth 'Quit & Win in 2002 which was held by WHO and KTL in Finland. 27398 participants from eleven cities in China took part in the contest. Then we had a one-year follow-up research from May to June in 2003.
Methods: A random sample of 1298 was surveyed by mailing, telephone and visiting.
