| Summary: | Introduction
Electronic cigarette use (vaping) has become increasingly popular
among youth. The aim of this study is to determine the cross-sectional association
of vaping, smoking, and dual use of these tobacco products with self-reported
serious difficulty concentrating, remembering, or making decisions (DCRMD),
because of a physical, mental, or emotional condition (PMEC) in US youth.
Methods
The 2018 National Youth Tobacco Survey (NYTS) data with 18535
youth were used for analysis. All included youth who answered whether they
have serious DCRMD and stated their vaping and smoking status. Multivariable
weighted logistics regression models were used to examine the association of
vaping and smoking with the risk of DCRMD in youth, considering a complex
sampling design.
Results
Ever dual users (AOR=4.19; 95% CI: 2.97–5.92), exclusive ever cigarette
smokers (AOR=1.50; 95% CI: 1.18–1.91) and exclusive ever e-cigarette users
(AOR=3.13; 95% CI: 2.25–4.34) had significantly higher odds of self-reported
DCRMD than never users in youth. Subgroup analysis on 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
(AOR=1.77; 95% CI: 1.27–2.45). Meanwhile, 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 (AOR=1.67; 95% CI: 1.25–2.22).
Conclusions
Vaping, smoking and dual use were associated with self-reported
serious difficulty concentrating, remembering, or making decisions because of a
physical, mental, or emotional condition in youth, which provided initial evidence
on the cross-sectional association between vaping and self-reported cognitive
problems.
