Results: The major findings categorized factors influencing adolescent highly-caffeinated beverage consumption into 'addiction factors,' 'health factors,' and 'change factors.' Conclusion: The analysis of trends in factors related to adolescent highly-caffeinated beverage consumption research indicates that previous studies have focused on exploring variables interacting with caffeinated beverage consumption and those causing caffeinated consumption, aiming to manage them. In the future, efforts should be directed towards identifying and managing variables causing physical and psychological changes related to adolescent highly-caffeinated beverage consumption.

Purpose: The purpose of the study was to investigate the changes in the prevalence of metabolic syndrome and its risk factors in Korean adolescents before and during the COVID-19 pandemic. Methods: The study employed a descriptive cross-sectional design. Data were obtained from the 2018 and 2020 Korea National Health and Nutrition Examination Surveys. Out of a total of 15,351 participants in the surveys, 971 adolescents aged 12 to 18 years were included. The data were analyzed using the rao-scott x2 test and t-test. Results: There was no significant difference in the prevalence of adolescent metabolic syndrome before and after the outbreak of COVID-19. As for general characteristics, changes in high blood pressure were confirmed from waist circumference, diastolic blood pressure, and metabolic syndrome risk factors. When analyzing the general characteristics according to gender, there were significant differences in waist circumference and diastolic blood pressure in boys. Concerning the risk factors for metabolic syndrome, there was a significant difference in high blood pressure in both boys and girls and in abdominal obesity in girls. Conclusion: Hypertension and abdominal obesity, which are risk factors for metabolic syndrome, should be managed by including them in the school health area. Communities and schools should take an active role in preparing the youth for healthy adulthood.

Conclusion: Based on our findings, it is necessary to implement disaster nursing simulation training to improve disaster nursing competency of college students.

Purpose: The purpose of this study was to compare the happiness of otaku college students to that of non-otaku college students. Methods: Data were collected using structured questionnaires targeting college students who visited the S Fair, which displayed and promoted contents related to animation, figures, comics, music, entertainers, etc. A total of 236 college students were included in the analysis. Descriptive statistics, t-test, ANOVA, and multiple regression analyses were carried out using SPSS 24.0. Results: As a result of the study, 71 students (30.1%) were otaku. The happiness score was 43.17±8.62 for otaku, and 40.21±10.44 for non-otaku. After controlling for significant covariates (age, major, economic status, job seeking stress, depression, life stress, social support, and self-esteem), otaku students had a significantly higher happiness score than non-otaku students (b=1.91, p=.043). Conclusion: It was found that otaku college students were happier than non-otaku students, even though the difference was not big. Therefore, this suggests that otaku activities may, to some extent, contribute to subjective mental health such as happines.

Purpose: The purpose of the study was to conduct a descriptive survey to examine the knowledge, infection prevention behaviors, and health beliefs regarding COVID-19 and to identify factors that influence infection prevention behaviors in elementary and middle school students based on the Health Belief Model. Methods: The study included 388 elementary and middle school students in Seoul, Gyeonggi, and Jeonbuk provinces. Data were collected from September 1 to September 15, 2023. The questionnaire consisted of 10 questions about COVID-19 knowledge, 13 questions about infection prevention behaviors, and 15 questions about health beliefs. The collected data were subjected to multiple hierarchical regression analyses. The cronbach’s ⍺ of infection prevention behaviors was 0.83, the KR-20 of COVID-19 related knowledge was 0.68, and the Cronbach’s ⍺ of COVID-19 related health beliefs was 0. 78. Results: In Model 1, females showed higher levels of infection prevention behaviors than males (β=.14, p=.006) and middle school students showed lower levels of infection prevention behaviors than elementary school students (β=-.10, p=.037). In Model 2, among COVID-19-related health beliefs, barriers had a significant negative effect on infection prevention behaviors (β=-.20, p<.001) and cues to action had a significant positive effect on infection prevention behaviors (β=.14, p=.037), indicating that lower barriers and higher cues to action were associated with higher levels of infection prevention behaviors. Conclusion: The results showed that prevention behaviors were associated with lower barriers and higher cues to action among COVID-19 health beliefs. Elementary and middle school students in Korea spend a lot of time in groups at private academies or school, which are closed spaces with poor ventilation, making them vulnerable to new infectious diseases such as COVID-19. Unlike adults, infectious diseases can have serious impact on their mental and social health. Therefore, it is necessary for schools to provide accurate and timely health education about COVID-19 to increase cues to action for elementary and middle school students in order to improve their infection prevention behaviors.

Purpose: The purpose of this study was to identify the influence of eHealth literacy on health promoting behaviors, thereby providing basic data for the development of interventions for health promoting behaviors among university students. Methods: Data were collected from 242 university students aged 19 and over in a university located in K province in South Korea. Participants responded to structured questionnaires in September 2018. eHealth literacy and health promoting behaviors were measured by eHealth Litaracy (EHL) and a translated version of the Health Promoting Lifestyle Profile (HPLP-II), respectively. The correlation between eHealth literacy and health promoting behaviors were analyzed using Pearson's correlation, and multiple regression analysis was carried out to examine the influence of eHealth literacy on health promoting behaviors. Results: The participants had a moderate level of eHealth literacy with the greatest score recorded in the sub-domain of functional eHealth literacy and the lowest in the sub-domain of critical eHealth literacy. Female students and students who majored in healthcare had higher levels of eHealth literacy than male students and those with non-healthcare majors. The degree of health promoting behaviors was moderate or lower with the highest score being in the sub-domain of interpersonal support and the lowest in the sub-domain of health responsibility. Health promoting behaviors had significant relationships with eHealth literacy, exercise hours, subjective health status, and health concerns. Multiple regression analyses revealed that the participants engaged more in health promoting behaviors when they had greater eHealth literacy (β=.18, p<.001), interest in their own health (β=.33, p<.001), exercise hours (β=.18~.23, p<.001), and subjective health status (β=.17~.18, p=.007~.031). Conclusion: In order to facilitate health promoting behaviors of university students, interventions for health promoting behaviors need to be developed including strategies to improve competencies relevant to critical eHealth literacy and to increase exercise hours.
