E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend analysis, 2014-2018.

Introduction:
This text provides an analysis of trends in e-cigarette use susceptibility among youth never users of e-cigarettes across five years (2014-2018) using data from the National Youth Tobacco Survey. The study examines prevalence of e-cigarette use susceptibility by race/ethnicity, sex, school level, other tobacco product (OTP) use, and levels of perceived harm of intermittent e-cigarette use by survey year. The text also tests for trends in e-cigarette use susceptibility across the survey years and assesses whether e-cigarette use susceptibility trends varied by race/ethnicity, sex, school level, OTP use, and perceived e-cigarette harm.

Key Points:

* The study found a linear and quadratic trend in e-cigarette susceptibility over time, with a linear increase in prevalence between 2014 and 2016 and a linear decrease between 2016 and 2018.
* E-cigarette susceptibility was associated with race, school level, OTP ever use, and e-cigarette harm perceptions across all survey years.
* hispanic youth, high school youth, and OTP ever users had higher odds of being susceptible to e-cigarettes compared to their counterparts.
* The study found that there was an increasing linear trend in the prevalence of e-cigarette susceptibility among youth who perceived e-cigarettes to be a little harmful, somewhat harmful, or a lot harmful.
* The study also found that there was a decreasing linear trend in e-cigarette susceptibility among youth who perceived e-cigarettes to be not harmful.
* The study found that females had higher odds of being susceptible to e-cigarettes compared to males.
* The study found that there was no association between school level and e-cigarette susceptibility.

Main Message:
The text highlights the importance of understanding trends in e-cigarette use susceptibility among youth and the need to identify subgroups that are more vulnerable to e-cigarette use. The study found that e-cigarette susceptibility was associated with race, school level, OTP ever use, and e-cigarette harm perceptions. The study also found that there was a linear increase in prevalence of e-cigarette susceptibility between 2014 and 2016 and a linear decrease between 2016 and 2018. The study suggests that targeted prevention interventions may be useful in reducing youth e-cigarette use and preventing future addiction. additionally, the study highlights the need to address the rise in flavored e-cigarette use among youth and the importance of implementing policies and regulations to prevent youth e-cigarette access and use.
