title: [Impact of intervention on tobacco related knowledge, attitudes and practice of smokers].
abstract: OBJECTIVE
  To evaluate the impact of intervention on tobacco related knowledge, attitudes and practice of smokers.
  
  
  METHODS
  An observational study was conducted among the smokers seeking counsel at smoking cessation clinic in our hospital from October 2008 to August 2013. First, a face to face counsel and mental intervention for more than 30 minutes was given to smoker, then 4 interventions through telephone call for 15-20 minutes for each time were conducted 1 week later, 1 month later, 3 months later and 6 months later, respectively. The controls were smokers receiving health examination in our hospital. No interventions were conducted among them. The tobacco related knowledge, attitudes and practice at baseline survey and follow up 1 year later were compared between intervention group and control group.
  
  
  RESULTS
  The intervention group included 414 smokers and the control group included 213 smokers. Intentional analysis indicated that the awareness/acceptance rates of 5 items about tobacco related knowledge and attitudes at follow up 1 year later was higher than those at baseline survey in intervention group. The smoking cessation rate was 27.3% in intervention group and 4.7% in control group. Multivariate logistic regression analysis indicated that the smoking cessation rate was positively correlated with intervention, female, highly nicotine dependence and positive change of tobacco related knowledge and attitudes (smoking can cause heart disease, all kinds of tobacco advertisements should be prohibited, smoking waste money and restaurant should be smoking free) with OR (95% CI): 2.85 (2.00-4.07), 3.34 (1.23-9.07), 2.78 (1.64-4.72), 2.30 (1.03-5.15), 5.33 (1.47-19.32), 6.32 (1.56-25.62) and 10.47 (2.25-48.84), respectively.
  
  
  CONCLUSIONS
  The awareness rate of tobacco related harm was high among the smokers seeking counsel at smoking cessation clinic. Systematic smoking cessation intervention can improve smokers' tobacco related knowledge and attitudes and increase smoking cessation rate.
