To evaluate the impact of a smoke-free campus policy on college students' smoking behaviors and attitudes.
The current study utilized repeated cross-sectional surveys with a nested 4-wave longitudinal cohort design. Data were collected from undergraduate students at two large matched public universities in Indiana before and after one of the campuses went smoke-free in January 2008. Baseline data were collected in fall 2007 (n=3266) and follow-up data were collected in fall 2009 (n=3207). In addition, volunteers provided longitudinal follow-up data at four different time points.
In the cross-sectional analyses, students exposed to the smoke-free campus policy demonstrated significant favorable changes in smoking behavior (16.5% to 12.8%, p<0.001), perceptions of peer tobacco use (73.6% to 66.8%, p<0.001), and smoking norms (45.5% to 40.4%, p<0.001) compared to students on the control campus. In the longitudinal analyses, students exposed to the smoke-free campus policy demonstrated these changes plus significant favorable changes in attitudes toward regulation of tobacco (83.2% to 89.9%, p<0.01).
The implementation of a smoke-free campus policy may be an effective intervention for reducing tobacco use among college students.
评估无烟校园政策对大学生吸烟行为和态度的影响。
本研究采用重复横断面调查和嵌套的 4 波纵向队列设计。数据来自印第安纳州两所大型公立大学的本科生，在其中一所校园于 2008 年 1 月实行无烟政策前后进行收集。基线数据于 2007 年秋季（n=3266）收集，随访数据于 2009 年秋季（n=3207）收集。此外，志愿者在四个不同时间点提供了纵向随访数据。
在横断面分析中，接触无烟校园政策的学生在吸烟行为（16.5%降至 12.8%，p<0.001）、对同伴烟草使用的看法（73.6%降至 66.8%，p<0.001）和吸烟规范（45.5%降至 40.4%，p<0.001）方面表现出显著的有利变化，与对照校园的学生相比。在纵向分析中，接触无烟校园政策的学生除了在对烟草监管的态度方面表现出这些变化外（83.2%升至 89.9%，p<0.01），还表现出显著的有利变化。
实施无烟校园政策可能是减少大学生吸烟的有效干预措施。
