E-cigarette use and cigarette smoking associated with inadequate sleep among U.S. young adults

Abstract

<b>Background:</b> Nicotine use can influence inadequate sleep, but less is known about the association of exclusive and dual use of electronic cigarettes (e-cigarettes) with combustible cigarettes in U.S. young adults. <b>Aims and Objectives:</b> This study assessed the associations between current (past 30-day) exclusive e-cigarette use, exclusive cigarette smoking, and dual e-cigarette and cigarette use and inadequate sleep among U.S. young adults. <b>Methods:</b> We performed an analysis of 2020 Behavioral Risk Factor Surveillance System data including 14,049 U.S. young adults ages 18-24 years. Inadequate sleep duration was assessed categorically using the American Academy of Sleep Medicine’s age-specific cutpoint of &lt;7 hours. A weighted multivariable logistic regression model was performed while adjusting for participants’ sex, race/ethnicity, education level, income level, body mass index, physical activity, mental health status, current alcohol use, and current smokeless tobacco use. <b>Results:</b> Concerning use patterns, 13% of young adults were exclusive e-cigarette users, 5% were exclusive cigarette smokers, and 4% were dual e-cigarette and cigarette users. Exclusive e-cigarette users (adjusted odds ratio [AOR]=1.44, 95% confidence interval [CI]=1.19-1.75) and exclusive cigarette smokers (AOR=1.68, 95%CI=1.26-2.23) were at increased odds to have inadequate sleep compared to nonusers. Dual e-cigarette and cigarette users were at 2.12 increased odds (95%CI=1.51-2.98) to have inadequate sleep compared to nonusers. <b>Conclusions:</b> Current use of e-cigarettes and cigarettes may&nbsp;influence inadequate sleep in U.S. young adults. Tobacco cessation efforts can encourage increased sleep health.
