中国年轻吸烟者电话戒烟咨询后的戒烟结果:纵向研究
2011/07/06
摘要
前言:年轻吸烟者在接受戒烟咨询后的吸烟形式尚不清楚。本试验旨在研究中国年轻吸烟者在接受戒烟咨询后的戒烟效果以及预测戒烟的因素。
方法:共402名中国年轻吸烟者入选本研究,年龄为12~25岁。这些患者通过戒烟热线进行咨询,并在首次电话咨询后的1周、1月和3、6个月进行电话随访。采用有限混合模型,通过基于SAS Proc Traj组的建模程序,研究戒烟轨迹。分层多分类logistic回归用于比较基线状态的戒烟意向、赞成吸烟的态度、社会影响、戒烟的自我效能、吸烟情况、戒烟史以及人口统计学参数。
结果:共有3个不同的戒烟结果组:戒烟者、吸烟下降者和持续吸烟者。戒烟者和吸烟下降者在初始咨询后的吸烟量上显著下降。基线状态下有戒烟意向、对戒烟有信心及认为戒烟很重要的年轻吸烟者,更有可能在6个月的随访期内戒烟。那些有赞成吸烟态度的年轻吸烟者,戒烟的可能性很小。
结论:结果揭示了能成功戒烟的年轻吸烟者的特征,可用于指导基于年轻吸烟者的心理社会特征,开发出更好的戒烟相关措施。短期的目标,如突然戒烟后吸烟量即刻减半,是促使年轻吸烟者成功戒烟的关键。

Abstract
INTRODUCTION: The smoking patterns of youth remain unknown after they have received smoking cessation counseling. This study aims to examine the quitting trajectories of Chinese youth smokers after they have received quitline services and to examine factors to predict their quitting trajectories.
METHODS: A total of 402 Chinese youth smokers (aged 12-25 years) called a quitline and participated in telephone follow-ups at 1 week, 1 month, and 3 and 6 months after initial telephone counseling. Finite mixture modeling was employed to examine the quitting trajectories by the SAS Proc Traj group-based modeling procedure. Hierarchical multinomial logistic regression was used to compare the baseline intention to quit smoking, prosmoking attitudes, social influences, self-efficacy to quit, smoking profile, quitting history, and demographic characteristics among the trajectory groups.
RESULTS: Three distinct quitting trajectory groups were identified: quitters, reducers, and persistent smokers. Both quitters and reducers dramatically reduced the level of their cigarette consumption immediately after initial counseling. Youth smokers who were intended to quit at baseline, perceived confidence to quit, and perceived importance of quitting were more likely to have successfully quit smoking at six-month follow-up. Those who had prosmoking attitudes were less likely to quit smoking.
CONCLUSION: The findings reveal the profiles of youth smokers who can quit successfully and can guide the development of better and relevant interventions based on the psychosocial characteristics of youth smokers. Short-term goals such as an abrupt quit attempt or immediately reducing cigarette consumption by half may be the key to help youth smokers quit successfully.
