Early trajectories of cigarette and ENDS use among young adult recent Latino immigrants to U.S.

Abstract

Background: Recent Latino immigrants (RLIs) to the U.S. have shown high smoking rates during their first year since arrival, raising concern about future escalation of tobacco use.

Objective: To examine trajectories of cigarette and Electronic nicotine delivery systems (ENDS) use among RLIs from pre-immigration (T0) through their first (T1) and second (T2) year in the U.S.

Methods: Data originated from a longitudinal study of 540 (50% females) RLIs aged 18-34. Inclusion criteria was residing in Miami/Dade County (MDC), and having immigrated from a Latin American country within the past year. Trajectories were identified by using the Proc Traj procedure (SAS©, v 9.4).

Results: Rates of cigarette use per month declined from 11.8 days/month in T0 to 4.9 d/m in T2. Rates for ENDS use however, increased from T0 (1.1 d/m) to T1 (1.8 d/m) and then lowered back to 0.9 d/m in T2. Four separate cigarette and e-cigarette use trajectories were identified. Only one of them showed increase in cigarette (10.6% of RLIs), and ENDS use (4.5% of RLIs). Being male, and not completing high school were significant factors in explaining smoking trajectories. Being younger than 30 years old was largely associated with ENDS use. No evidence of a substitution effect between cigarette and ENDS use was found.

Discussion/Conclusions: Interventions to discourage tobacco use among Latino immigrants should begin early in the immigration process, aimed to preserve initial reductions and dissuade those at risk of increased tobacco use overtime.
