Poor sleep is associated with energy drinks consumption among Korean adolescents

Objective: A growing number of Korean adolescents consume energy drinks, which may increase the risk of obesity, anxiety and insomnia. We examined whether poor sleep was associated with energy drink consumption among study participants. Design: We used a cross-sectional design. Setting: The Korea Youth Risk Behavior Web-Based Survey data from 2019. Participants: To determine the association between sleep and energy drink consumption, we compared the independent variables for 50,455 adolescents in Korea (aged 14-19 years) using multivariate logistic regression and sensitivity analyses. Results: In Korea, 69 center dot 5 % adolescents consumed energy drinks, 17 center dot 1 % slept for less than 5 h, 22 center dot 4 % slept for 5-6 h, 23 center dot 8 % slept for 6-7 h, 19 center dot 9 % slept for 7-8 h and 16 center dot 7 % slept for 8 h or more. Regarding sleep satisfaction, 21 center dot 0 % reported sufficient, 32 center dot 6 % reported just enough and 46 center dot 5 % reported insufficient. Regarding sleep duration, it was found that less than 5 h (OR, 2 center dot 36; 95 % CI (2 center dot 14, 2 center dot 60)) and lower sleep satisfaction (OR, 1 center dot 12; 95 % CI (1 center dot 03, 1 center dot 21)) were highly associated with energy drink consumption, with statistical significance at P < 0 center dot 05. Adolescents with lower sleep duration (adjusted OR (aOR), 6 center dot 37; 95 % CI (4 center dot 72, 8 center dot 61)) and a lack of sleep satisfaction (aOR, 1 center dot 44; 95 % CI (1 center dot 16, 1 center dot 78)) reported drinking a high amount of energy drinks, that is, at least once a day. Conclusion: In addition to efforts to decrease the amount of energy drinks consumed, sleep hygiene education needs to be strengthened.
