As smoking decreases in the population, the remaining smoking population will change, and cessation initiatives will have to incorporate strategies designed for these smokers.
To study patterns of response to a cessation intervention composed of 20 televised segments and the American Lung Association Freedom from Smoking in 20 Days manual, this study compared cessation rates over 24 months in a cohort of smokers who registered for a cessation program with those in a cohort selected from the smoking population at large.
At post intervention, multiple point prevalence of cessation among participants, adjusted for baseline smoking, was 14% among registrants and 6% in the population; at 24 months the adjusted rates were 6% and 2%, respectively. Heavy smokers benefited more than light smokers, and there was a consistent dose-response relationship between extent of exposure to the intervention and cessation.
The effects of the intervention were strongest for those who read the manual and watched the programs daily. Manual use was important, and those who did not read it did not appear to benefit. Compared to the population and given full participation, heavy smokers benefited more than lighter smokers.
随着人群中吸烟率的下降，剩余吸烟人群将会发生变化，戒烟倡议必须纳入针对这些吸烟者设计的策略。
为研究对由20个电视片段和美国肺脏协会《20天戒烟》手册组成的戒烟干预措施的反应模式，本研究比较了在一个注册纳入戒烟项目的吸烟者队列与一个从广大吸烟人群中选取的队列中24个月内的戒烟率。
干预后，经基线吸烟情况调整后，参与者中的多点戒烟患病率在注册者中为14%，在总体人群中为6%；在24个月时，调整后的比率分别为6%和2%。重度吸烟者比轻度吸烟者受益更多，并且干预暴露程度与戒烟之间存在一致的剂量反应关系。
对于那些每天阅读手册并观看节目的人，干预效果最为显著。使用手册很重要，未阅读手册的人似乎未从中受益。与总体人群相比，在充分参与的情况下，重度吸烟者比轻度吸烟者受益更多。
