Understanding susceptibility to e-cigarettes: A comprehensive model of risk factors that influence the transition from non-susceptible to susceptible among e-cigarette naïve adolescents.

Introduction:
This text is a research article that examines risk factors associated with becoming susceptible to e-cigarette use among adolescents. The study uses data from the Texas Adolescent Tobacco and Marketing Surveillance system (TATAMS) to identify risk factors for susceptibility to e-cigarettes over one year of follow-up among 6th, 8th, and 10th grade students who were e-cigarette naive at baseline. The study stratified analyses by grade level to identify risk factors among e-cigarette non-users and to inform the development of evidence-based prevention and intervention strategies.

Key Points:

* The study found that the incidence of susceptibility to e-cigarettes at 12 months did not vary by grade level, but risk factor profiles did vary.
* Among 6th graders, family influence, use of other substances, and positive affect were important.
* Adolescents transitioning from 8th grade to high school presented the greatest number of risk factors, including social and normative influences.
* Only sensation seeking increased the risk of susceptibility to e-cigarettes among 10th graders.
* The study used a comprehensive model to assess multiple risk factors and account for potential shared variance.
* The study weighted the data to allow the study population to be representative of students enrolled in the 6th, 8th, and 10th grades in five Texas counties.
* The study used validated measures from reliable sources, including the Population Assessment of Tobacco and Health study.

Main Message:
The main message of the text is that there are various risk factors associated with becoming susceptible to e-cigarette use among adolescents, and these risk factors vary by grade level. The study highlights the importance of examining these risk factors to inform prevention and intervention strategies. The study's findings suggest that early intervention may be necessary to prevent the transition to e-cigarette susceptibility, particularly among 6th graders who may be influenced by family members' e-cigarette use or other substances. Furthermore, the study emphasizes the need to address social and normative influences during the transition to high school to prevent susceptibility to e-cigarettes. Overall, the study underscores the importance of comprehensive prevention and intervention strategies that consider the various risk factors associated with e-cigarette use among adolescents.
