AGE AND READINESS TO QUIT SMOKING

The relationship between planning to quit smoking within the next 3 months and demographic characteristics, smoking history, attitudes and beliefs about smoking cessation, and motivation was analyzed among smokers in three age groups: 18 to 29, 30 to 49, and 50 years or older. Using random-digit dialing, telephone interviews were completed with 2,353 smokers before initiating a self-help, minimal-contact intervention in the Chicago metropolitan area. Multiple logistic regression was used to identify factors that predicted planning to quit within the next 3 months. The two youngest age groups were most likely to have attitudes favorable to being ready to try to quit smoking (they were more concerned about health effects of smoking, perceived a greater reduction in the likelihood of getting lung cancer, were more determined to quit, and were more confident in their ability to quit). Among all three age groups, one-fourth or less planned to quit within the next 3 months, and desire to quit was the strongest predictor in each group. Among smokers who planned to quit someday, the oldest were most likely to plan to quit within the next 3 months. The findings show that there are important age-related differences in readiness to quit smoking that should be considered when planning and evaluating smoking cessation interventions.
