Profile and patterns of dual use of e-cigarettes and combustible cigarettes among Mexican adults

Abstract

Objective: To describe the profile and patterns of dual uses (n954) and exclusive cigarette users (n2 070) and determine the correlates of more frequent e-cigarette use among dual users and their reasons for e-cigarette use.

Materials and methods: An online survey of Mexican adult smokers. Logistic models regressed dual-use (exclusive smoking vs. dual user) on sociodemographic, smoking varia-bles and substance use behaviors. We conducted censorial binomial models to estimate the correlates of frequency of e-cigarette use among dual users.

Results: Dual users were younger had higher education (AOR2.22) and higher levels of smoking dependence (AOR1.31), preferred cigarettes with flavor capsules (AOR1.58) and had recently attempted to quit smoking (AOR1.38). Marijuana use and being daily smokers were correlates of higher frequency of use among dual users.

Conclusion: Dual users had a higher risk profile than exclusive smokers, which was even more prominent in dual-users who used e-cigarettes frequently.
