association of electronic cigarette use with self-reported difficulty concentrating, remembering, or making decisions in US youth.

Introduction:
This text is a research paper that examines the association between electronic cigarette use (vaping), smoking, and dual use of these tobacco products with self-reported difficulty concentrating, remembering, or making decisions due to a physical, mental, or emotional condition (DCRMD) in US youth. The study uses data from the 2018 National Youth Tobacco Survey (NYTS) and employs multivariable weighted logistic regression models to examine the association.

Key Points:

* The study found that ever dual users, exclusive ever cigarette smokers, and exclusive ever e-cigarette users had significantly higher odds of self-reported DCRMD than never users in youth.
* Subgroup analysis revealed that exclusive ever e-cigarette users who started vaping in middle school or earlier had significantly higher odds of self-reported DCRMD compared to those who started vaping in high school.
* Male youth who were exclusive ever e-cigarette users had higher odds of self-reported DCRMD than female youth who were exclusive ever e-cigarette users.
* The study controlled for various covariates, including age, gender, race, other tobacco use, cravings for using tobacco product, number of days of any tobacco product use during the past 30 days, whether smoked cigarettes at least one day in past 30 days, and age of first use of e-cigarettes.
* Multicollinearities among covariates were examined using the variance inflation factor (VIF) values to ensure that no multicollinearities existed among the covariates.
* The study used the purposeful model selection method to select significant covariates in the final weighted multivariable logistic regression model.
* The study found an association between vaping, smoking, and dual use with self-reported DCRMD in US youth, providing initial evidence on the cross-sectional association between vaping and self-reported cognitive problems.

Main Message:
The study suggests that vaping, smoking, and dual use are associated with self-reported DCRMD in US youth. The findings highlight the importance of regulating tobacco products, especially e-cigarettes, to protect the health and well-being of young people. It is crucial to implement policies and programs that prevent youth from initiating tobacco use and help those who have already started to quit. The study underscores the need for further research on the long-term cognitive effects of vaping and smoking in youth.
