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.
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.
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.
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.
在三个年龄组（18至29岁、30至49岁以及50岁及以上）的吸烟者中，研究了三个月期间戒烟行为的预测因素。
通过随机数字拨号，对芝加哥大都市地区的1644名吸烟者在基线时和3个月随访时进行了电话访谈。使用多元逻辑回归来确定在每个年龄组以及按戒烟准备阶段预测尝试戒烟和戒烟的因素。
在沉思或准备阶段的吸烟者中，尝试戒烟或戒烟方面在年龄上没有显著差异。然而，预测这些行为的因素存在重要的年龄差异。一般来说，在戒烟过程的三个阶段（沉思、准备和行动）的每个阶段，不同因素在每个年龄组中预测戒烟行为。此外，在每个年龄组内，不同因素在每个阶段预测行为。
研究结果表明，所有年龄段的吸烟者都是戒烟干预的同等合适目标。此外，在规划和实施戒烟干预措施时，应考虑吸烟者在其吸烟生涯中存在的与年龄相关的重要差异。
