Patterns of alternative tobacco use among adolescent cigarette smokers.

INTRODUCTION: Alternative tobacco use among adolescents who smoke cigarettes is a growing public health concern, and evidence suggests that patterns of alternative tobacco use varies with respect to cigarette consumption and frequency of cigarette use. This study aimed to examine (a) whether variations in adolescent cigarette smoking and alternative tobacco use can be explained by underlying subtypes and (b) if these subtypes differ in their demographic and psychosocial characteristics.
METHODS: Using data from the 2009 National Youth Tobacco Survey, latent class analysis (LCA) was used to identify patterns of cigarette smoking and alternative tobacco use among 2746 current (past 30-day) smokers. After identification, classes were analyzed using multinomial logistic regression to examine differences based on demographics and smoking-related characteristics.
RESULTS: Four of the six latent classes identified (non-daily light smokers, chippers, chippers-Indulgent, intermittent smokers) reflected consumption, frequency, and history of cigarette use characteristics commonly attributed to light and intermittent smokers, and the remaining two classes (daily smokers, daily smokers-Indulgent) presented cigarette use behaviors commonly attributed to daily smokers. There were clear class differences in levels of alternative tobacco product use, demographics, and psychosocial characteristics.
CONCLUSIONS: Study findings are consistent with previous work demonstrating demographic and psychosocial differences between cigarette smokers based on their alternative tobacco use. The six latent classes identified highlight the importance of including measures of alternative tobacco use when characterizing adolescent cigarette smokers as well as recognizing and tailoring interventions toward these different groups of tobacco users.
