Abstract
OBJECTIVE: To examine baseline characteristics and biochemically verified 1-, 4-, and 6-month tobacco quit rates among college students enrolled in a Quit and Win cessation trial, comparing those who concurrently smoke both hookah and cigarettes with those who deny hookah use. METHODS: Analyses were conducted on data from 1217 college students enrolled in a Quit and Win tobacco cessation randomized clinical trial from 2010-2012. Multivariable logistic regression (MLR) analyses examined group differences in baseline characteristics and cotinine verified 30-day abstinence at 1, 4, and 6-month follow-up, adjusting for baseline covariates. RESULTS:Participants smoked 11.5(±8.1) cigarettes per day on 28.5(±3.8) days/month, and 22% smoked hookah in the past 30days. Hookah smokers (n=270) were more likely to be male (p<0.0001), younger (p<0.0001), report more binge drinking (p<0.0001) and score higher on impulsivity (p<0.001). MLR results indicate that hookah users, when compared to non-users, had a 36% decrease in odds of self-reported 30-day abstinence at 4-months (OR=0.64, 95% CI=0.45-0.93, p=0.02) and a 63% decrease in odds in biochemically verified continuous abstinence at 6-months (OR=0.37, CI=0.14-0.99, p=0.05). CONCLUSION:College cigarette smokers who concurrently use hookah display several health risk factors and demonstrate lower short and long-term tobacco abstinence rates.
