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.
在三个年龄组（18至29岁、30至49岁、50岁及以上）的吸烟者中，分析了未来3个月内戒烟计划与人口统计学特征、吸烟史、对戒烟的态度和信念以及动机之间的关系。通过随机数字拨号，在芝加哥大都市地区开展一项自助式、低接触干预措施之前，对2353名吸烟者完成了电话访谈。采用多元逻辑回归来确定预测未来3个月内有戒烟计划的因素。最年轻的两个年龄组最有可能持有有利于准备尝试戒烟的态度（他们更关注吸烟对健康的影响，认为患肺癌的可能性降低幅度更大，更有决心戒烟，并且对自己戒烟的能力更有信心）。在所有三个年龄组中，四分之一或更少的人计划在未来3个月内戒烟，并且在每个组中，戒烟意愿是最强的预测因素。在那些计划有朝一日戒烟的吸烟者中，年龄最大的人最有可能计划在未来3个月内戒烟。研究结果表明，在准备戒烟方面存在重要的年龄差异，在制定和评估戒烟干预措施时应予以考虑。
