Combustible and electronic cigarette use and insufficient sleep among U.S. high school students.

Abstract

The study aimed to investigate the relationships between current exclusive e-cigarette use, exclusive combustible cigarette smoking, and dual use of e-cigarettes and combustible cigarettes, and insufficient sleep among U.S. adolescents. We conducted a secondary data analysis of the 2017 Youth Risk Behavior Survey including 11,296\u202fU.S. high school students. Current (past 30-day) tobacco use groups included exclusive e-cigarette users, exclusive combustible cigarette smokers, and dual-product users. We performed weighted unadjusted and adjusted logistic regression analyses. Insufficient sleep was defined as <8\u202fh/night and\u202f<\u202f7\u202fh/night. Overall, 73.4% of adolescents reported insufficient sleep <8\u202fh/night. Compared with non-tobacco users, exclusive e-cigarette users were more likely to report insufficient sleep <8\u202fh/night (odds ratio [OR]\u202f=\u202f1.55, 95%CI\u202f=\u202f1.12-2.14; adjusted OR [aOR]\u202f=\u202f1.57, 95%CI\u202f=\u202f1.01-2.43) and\u202f<\u202f7\u202fh/night (OR\u202f=\u202f1.55, 95%CI\u202f=\u202f1.19-2.01; aOR\u202f=\u202f1.61, 95%CI\u202f=\u202f1.16-2.24). Dual-product users were at increased odds to report insufficient sleep <8\u202fh/night (OR\u202f=\u202f3.15, 95%CI\u202f=\u202f1.87-5.32) and\u202f<\u202f7\u202fh/night (OR\u202f=\u202f2.64, 95%CI\u202f=\u202f1.87-3.72; aOR\u202f=\u202f1.73, 95%CI\u202f=\u202f1.14-2.62) than non-tobacco users. Exclusive combustible cigarette smokers were less likely to report insufficient sleep <8\u202fh/night (aOR\u202f=\u202f0.49, 95%CI\u202f=\u202f0.29-0.84) than non-tobacco users, but no differences were found based on insufficient sleep <7\u202fh/night. When comparing current use groups, exclusive e-cigarette users were at 3.20 increased odds (95%CI\u202f=\u202f1.65-6.22) and dual-product users were at 3.26 increased odds (95%CI\u202f=\u202f1.51-7.03) to report insufficient sleep <8\u202fh/night when compared with exclusive combustible cigarette smokers after covariate adjustment. Dual-product users were 1.89 times more likely (95%CI\u202f=\u202f1.01-3.51) to report insufficient sleep <7\u202fh/night when compared with exclusive combustible cigarette smokers. School-based prevention efforts for tobacco use may promote sufficient sleep in youth.
