title: Age and smoking cessation behaviors.
abstract: BACKGROUND
  Predictors of smoking cessation behaviors during a 3-month period were examined among smokers in three age groups: 18 to 29, 30 to 49, and 50 years or older.
  
  
  METHODS
  Using random-digit dialing, telephone interviews were completed with 1,644 smokers in the Chicago metropolitan area at baseline and at a 3-month follow-up. Multiple logistic regression was used to identify factors that predicted trying to quit smoking and quitting smoking within each age group and by stage of readiness to quit smoking.
  
  
  RESULTS
  There were no significant differences by age in trying to quit smoking or in quitting smoking among smokers in the contemplation or preparation stages. However, there were important age differences in the factors that predicted those behaviors. In general, different factors predicted smoking cessation behaviors in each age group at each of three stages of the smoking cessation process (contemplation, preparation, and action). Also, within each age group, different factors predicted the behavior at each stage.
  
  
  CONCLUSIONS
  The findings suggest that smokers of all ages are equally appropriate targets for smoking cessation interventions. Moreover, there are important age-related differences among smokers over the course of their smoking careers that should be considered when planning and implementing smoking cessation interventions.
