Longitudinal Patterns of Multiple Tobacco and Nicotine Product Use Among Texas College Students: a Latent Transition Analysis

Diverse tobacco and nicotine products have altered the terrain of tobacco use behaviors. Limited research has examined contemporary patterns of use among young adults. This study identified tobacco and nicotine product use groups and examined changes in young adults’ use patterns, across a 1.5-year period. Participants were 5,482 18–29-year-old students (M age = 20.5, SD = 2.36; 63% female) from 24 Texas colleges who completed a four-wave bi-annual online survey. Latent transition analysis was used to identify groups from 10 items (ever and current use of cigarettes, cigars, smokeless tobacco, e-cigarettes, and hookah) and to examine probabilities of transitioning between groups over four waves. Five groups were identified: Non-users (30%), Poly-experimenters (26%), Hookah experimenters (18%), E-cigarette & hookah experimenters (15%), and Poly-cigarette users (11%). Few students transitioned between groups over time. Poly-cigarette users had the highest average probability of remaining stable over time (1.00), followed by E-cigarette & hookah experimenters (.97), Non-users (.94), Poly-experimenters (.93), and Hookah experimenters (.92). All groups became more stable over time except Hookah experimenters whose members were most likely to transition to Poly-cigarette users or other experimenter groups. The greatest transition was from Poly-experimenters to Poly-cigarette users with probabilities of .10, .08, and .03 for transitioning between waves one and two, two and three, and three and four, respectively. There was substantial poly-use and experimentation, which may explain little movement between groups over the 1.5-year time period and underscores the need for prevention programs targeting multiple product use among college students.
