We conducted a group-randomized trial to increase smoking cessation and decrease smoking onset and prevalence in 30 colleges and universities in the Pacific Northwest.
Random samples of students, oversampling for freshmen, were drawn from the participating colleges; students completed a questionnaire that included seven major areas of tobacco policies and behavior. Following this baseline, the colleges were randomized to intervention or control. Three interventionists developed Campus Advisory Boards in the 15 intervention colleges and facilitated intervention activities. The freshmen cohort was resurveyed 1 and 2 years after the baseline. Two-years postrandomization, new cross-sectional samples were drawn, and students were surveyed.
At follow-up, we found no significant overall differences between intervention and control schools when examining smoking cessation, prevalence, or onset. There was a significant decrease in prevalence in private independent colleges, a significant increase in cessation among rural schools, and a decrease in smoking onset in urban schools.
Intervention in this college population had mixed results. More work is needed to determine how best to reach this population of smokers.
我们进行了一项群组随机试验，旨在增加太平洋西北地区 30 所学院和大学的戒烟率，减少吸烟的开始和流行。
从参与的学院中抽取学生的随机样本，对新生进行过度抽样；学生完成了一份包括烟草政策和行为七个主要领域的问卷。在此基线之后，将学院随机分为干预组和对照组。三名干预者在 15 所干预学院中成立了校园咨询委员会，并促进了干预活动。在基线后 1 年和 2 年对新生队列进行了重新调查。在随机分组后两年，抽取了新的横断面样本，并对学生进行了调查。
在随访中，当我们检查戒烟、流行率或开始吸烟时，我们没有发现干预组和对照组之间的总体差异。私立独立学院的流行率显著下降，农村学校的戒烟率显著增加，城市学校的吸烟开始率下降。
在这个大学生群体中的干预效果参差不齐。需要做更多的工作来确定如何最好地接触到这个吸烟人群。
