Sleep and energy drink consumption among Norwegian adolescents – a cross-sectional study

Abstract

Background: Adolescents are recommended to get 8–10h of sleep at night, yet more than 80% fail to obtain this goal. Energy drink (ED) consumption has been linked to later bedtime in adolescents. Therefore, we aimed to investi gate the potential association between ED consumption and sleep duration, and shuteye latency among adolescents in Norway. Methods: This study was based on data from 15- to 16-year-old adolescents living in Oppland County in 2017. In total, 1353 adolescents were included in the analysis. Multiple regression models were used to estimate the associa tions between the frequency of ED consumption with sleep duration, shuteye latency, and getting 8h of sleep. Results: Forty-six point fve percent of the adolescents reported sleeping more than 8h at night. Those who reported ED consumption at any frequency had signifcantly shorter sleep duration than those who did not. On aver age, high consumers of ED (consuming ED≥4 times a week) had 0.95 (95% CI: 0.61, 1.28) hours (i.e., 57min) less sleep than those who never consumed ED. In addition, high consumers had more than 25min (95% CI: 13.95, 36.92) longer shuteye period than those who never consumed ED. Conclusion: Most ED consumers fail to obtain the recommended 8h of sleep at night, which could be a conse quence of shorter sleep duration and longer shuteye latency. We found a dose-response relationship between frequency of ED consumption and reduced sleep. Yet, the potential long-term efects of both ED consumption and insufcient sleep among adolescents remain unclear.
