Logistic regression analyses of any exposure to secondhand smokea Discussion In our large sample of undergraduate students at 10 universities in North Carolina, we found high rates of self-reported SHS exposure. Some 83% of students reported any exposure in the 7 days preceding the survey. Exposure in a restaurant or bar was the most common (reported by 65% of students), followed by exposure at home or in the same room as a smoker (55%) and in a car (38%). A number of variables were found to be related significantly to either site-specific or any exposure to SHS. Daily smokers and nondaily smokers were more likely than nonsmokers to report exposure, which is not surprising given that they are more likely than other students to have friends who smoke and to frequent or live in locations where smoking occurs.

Similarly, students who binge drink were more likely than other students to report exposure, which is likely to reflect the co-occurrence of smoking and drinking among college students (McKee, Hinson, Rounsaville, & Petrelli, 2004; Sher, Gotham, Erickson, & Wood, 1996). Living in residence locations associated with smoking, such as Greek houses and off-campus housing, also was associated with self-reported exposure. Exposure patterns by age reflect the easier access that older students may have to drinking establishments. Individuals younger than 21 years were less likely than those of legal age to report exposure in a bar or restaurant; those aged 18�C20 years were more likely than those aged 21 years or older to report exposure in a car or at home.

A number of background characteristics were associated with exposure in one or more locations, including female gender, White race, and higher parental education levels. Characteristics of the larger school environment also were associated with the likelihood of exposure. The overall campus smoking rate was associated positively with reported exposure in a car, at home or in the same room, and in any location. Interestingly, attending a campus that was in the intervention condition of the SPARC trial, which focuses on policy, enforcement, and awareness changes to the campus and community environment to reduce high-risk drinking by students, was related negatively to reported exposure in bars and restaurants. Students Dacomitinib attending one of the two private universities were less likely to report exposure than were those at one of the eight public schools in the sample.
