Question

Objectives: We examined the relationships between e-cigarette use and subsequent cigarette smoking behaviors at 6- and 12-month follow-ups among young adults. Methods: Participants were1829 year-old current and former cigarette smokers (N = 627) at 24 Texas colleges, participating in a 3-wave study. Multi-level, multivariable logistic regression models, accounting for school clustering, examined the impact of self-reported use of e-cigarettes on cigarette smoking status at 6- and 12-month follow-ups. Two mutually exclusive groups of e-cigarette users were examined: those that used for cigarette smoking cessation and those that used for reasons other than cessation. Baseline covariates included socio-demographics, past quit attempts, nicotine dependence,
cigarettes per day, and other tobacco use. Results: Use of e-cigarettes for cigarette smoking cessation was associated with increased odds of cigarette smoking cessation at 6- and 12-month follow-ups, while using e-cigarettes for other reasons was not, when adjusting for covariates. Conclusions: Use of e-cigarettes for cigarette smoking cessation may reduce cigarette smoking rates in young adult college students. Additional research is needed examining e-cigarettes as a complement to evidence-based cessation resources that are associated with cigarette smoking cessation among young adults.

What was the research question in this study?

How many observations were there in this study?

What is the dependent variable?

Is this study basic or applied research?

What are two of the controlled variables?

Explanation / Answer

1. There were 627 observations in the study . These were 18-29 years old current and former cigarette smokers at 24 Texas colleges, who participated in a 3-wave study.

2. Subsequent cigarette smoking behavior is a dependent variable, which is subject to use of e-cigarette.

3. It is an applied research in the sense that the objective of the research question is to reduce cigarette smoking rates in young adults.

4. Two of the controlled variables are users who use e-cigarettes for cigarette smoking cessation and those who use for reasons other than cessation.
