A Longitudinal Analysis of Tobacco Use in Younger and Older U.S. Veterans

United States (U.S.) veterans are prone to higher rates of smoking and smoking-related disease. We describe the prevalence of cigarette and non-cigarette product use and determine longitudinal predictors of tobacco use transitions in this vulnerable population. Data are from Waves 1 (2013-2014) and 2 (2014-2015) of the adult cohort in the Population Assessment of Tobacco and Health. Wave 1 prevalence was calculated for past 30-day use of all queried tobacco products, and compared by veteran status. Weighted multinomial logistic regression was used to determine predictors-demographics, substance use, and physical and psychological comorbidities-of tobacco use transitions (continued use, initiation, and cessation) among veterans. Compared to non-veterans, use of nearly all tobacco products was significantly higher among veterans and was highest among younger veterans. Compared to continued nonusers, continued users were more likely to: be of younger age (OR = 0.95, 95% CI: 0.95-0.96), have poorer physical health (OR = 1.58, 95% CI: 1.22-2.06) and mental health (OR = 1.48, 95% CI: 1.18-1.85), report substance use (OR = 1.79, 95% CI: 1.21-2.64), and report problematic alcohol use (OR = 4.23, 95% CI: 2.38-7.52) and were less likely to be female (OR = 0.57, 95% CI: 0.35-0.93). Compared to continued nonusers, initiators were more likely to report problematic alcohol use (OR = 8.63, 95% CI: 3.79-19.63), and those in the cessation category were more likely to be of younger age (OR = 0.97, 95% CI: 0.95-0.99). Cigarette and non-cigarette use is especially prevalent among young veterans, so prevention should begin during military service. Tobacco cessation programs should be tailored for this population, incorporating aspects related to concomitant health conditions.
