本研究试图在一组随访超过13年的吸烟者中确定戒烟的预测因素。数据报告的6，603人居住在美国20个社区之一，参与了国家癌症研究所的社区戒烟干预试验（COMMIT）研究，是1988年COMMIT试验中的当前吸烟者，并在1988年，1993年和2001年完成了详细的烟草使用电话调查。一个人被归类为前吸烟者，如果在随访时，他或她报告不吸烟至少6个月前的采访。1993年和2001年还对戒烟的原因和方法进行了评估。在1988年的吸烟者中，到1993年有24%的人戒烟，到2001年有42%的人不吸烟。最常被引用的戒烟原因是健康和成本原因，而近年来戒烟的辅助方法更常见。尼古丁依赖的措施与戒烟的关系比动机的措施更密切。其他预测因素包括男性、年龄较大、收入较高和饮酒频率较低，但当戒烟以及其他烟草产品被视为结果时，性别效应不再存在。目前的研究表明，尼古丁依赖是预测吸烟者长期戒烟的主要因素。这一发现对烟草控制政策和治疗方法具有影响。
The present study attempted to identify predictors of smoking cessation in a cohort of cigarette smokers followed over 13 years. Data are reported on 6,603 persons who resided in one of 20 U.S. communities involved in the National Cancer Institute's Community Intervention Trial for Smoking Cessation (COMMIT) study, were current smokers in the COMMIT trial in 1988, and completed detailed tobacco use telephone surveys in 1988, 1993, and 2001. A person was classified as a former smoker if at the time of follow-up he or she reported not smoking for at least 6 months prior to the interview. Reasons and methods for quitting also were assessed in 1993 and 2001. Among smokers in 1988, 24% had stopped smoking by 1993 and 42% were not smoking by 2001. The most frequently cited reasons for quitting were health and cost reasons, while assisted methods to quit were more common in more recent years. Measures of nicotine dependence were much more strongly associated with cessation than measures of motivation. Other predictors included male gender, older age, higher income, and less frequent alcohol consumption, although the gender effect no longer existed when cessation from cigarettes as well as other tobacco products was considered as the outcome. The present study shows that nicotine dependence is a major factor predicting long-term cessation in smokers. This finding has implications for tobacco control policy and treatment approaches.
