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 30 days. 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. [ABSTRACT FROM AUTHOR]

Abstract: Objective: Noncigarette tobacco products are increasingly popular. Researchers need to understand multiple tobacco product use to assess the effects of these products on population health. We estimate national prevalence and examine risk factors for multiple product use. Method: We calculated prevalence estimates of current use patterns involving cigarettes, cigars, electronic cigarettes, hookah, smokeless tobacco, and snus using data from the 2012 RTI National Adult Tobacco Survey (N=3627), a random-digit-dial telephone survey of adults aged 18 and over. Associations between use patterns (exclusive single product and multiple products) and demographic characteristics were examined using Pearson chi-square tests and logistic regression. Results: 32.1% of adults currently use 1 or more tobacco products; 14.9% use cigarettes exclusively, and 6.6% use one noncigarette product exclusively, 6.9% use cigarettes with another product (dual use), 1.3% use two noncigarette products, and 2.4% use three or more products (polytobacco use). Smokers who are young adult, male, never married, reside in the West, and made prior quit attempts were at risk for multiple product use. Conclusions: Over 10% of U.S. adults use multiple tobacco products. A better understanding of multiple product use involving combustible products, like cigars and hookah, is needed. Multiple product use may be associated with past quit attempts. [Copyright &y& Elsevier]
