Background: In Japan, the sales of energy drinks (ED) are growing rapidly. This has led to concerns that consumption of ED could have a negative health impact for individuals, including children.Objective: The purpose of this study was to confirm the intake of ED, the characteristics of consumers' physical symptoms/behaviors, and the perception of ED based on the results of a questionnaire survey for school children.Methods: The subjects were 5,984 children from 5th grade of elementary schools to 3rd grade of high school in 16 schools (5 elementary schools, 6 junior high schools, 5 high schools) at 6 rural and metropolitan Japanese prefectures. All investigations were conducted from May 2018 to March 2019. The questionnaire used in this study gathered information regarding ED intake, physical symptoms/behaviors, and the perception of ED.Results: The main results in this study were as follows. 1) Older students were more consume ED than younger students, and boys were more than girls to consume ED (elementary school: 45.5% boys, 27.9% girls, junior high school: 58.0% boys, 32.8% girls, and high school: 67.6% boys, 45.4% girls). 2) The analysis of the relationship between the ED intake frequency and physical symptoms indicated that the complaints of physical symptoms such as ‘headache (OR=1.573, 95% CI=1.281-1.931),' ‘stomachache (OR=1.545, 95% CI=1.224-1.949),' ‘appetite loss (OR=1.629, 95% CI=1.293-2.053),' ‘nausea (OR=1.667, 95% CI=1.251-2.222),' ‘tiredness (OR=1.285, 95% CI=1.023-1.614),' ‘lethargy (OR=1.382, 95% CI=1.120-1.706),' ‘dizziness (OR=1.369, 95% CI=1.108-1.692),' ‘fogginess (OR=1.621, 95% CI=1.231-2.134),' ‘cardiac pain (OR=1.537, 95% CI=1.168-2.021)' and ‘malaise (OR=1.557, 95% CI=1.267-1.915)' were higher in the group who consumed ED habitually (more than once a week). Similarly, in the analysis of the relation between the ED intake frequency and behaviors, ‘late bedtime (OR=1.338, 95% CI=1.092-1.640),' ‘bad sleep onset (OR=1.649, 95% CI=1.311-2.074),' ‘wake after sleep onset (OR=2.056, 95% CI=1.528-2.766)' and ‘lack of breakfast (OR=3.453, 95% CI=2.546-4.684)' were also higher in the habitual ED intake group. 3) The four factors, ‘vitality', ‘vogue,' ‘ineptness' and ‘distrust' were extracted regarding students' perception of ED held by children. Additionally, it was confirmed that the habitual ED intake group had higher factor scores of ‘vitality' and ‘vogue,' while their factor scores of ‘ineptness' and ‘distrust' were also significantly lower.Conclusion: In this study, we were able to show the real state of ED intake, the characteristics of consumers' physical symptoms/behaviors, and the perception of ED. Therefore, social countermeasures were considered necessary.
