Purpose: The purpose of this study was to understand the impact of long- and short-term energy drinks on anxiety-like, depressionlike, and cognitive behavior in adolescent rats. Methods: Adolescent rats (age six weeks) were randomly classified into a control group (CON), a long-term administration group (LT), and a short-term administration group (ST). The LT group was orally administered 1.5 mL/100 g (body weight) of energy drink twice daily for 14 days, the ST group was orally administered for one day, and the control group applied the same amount of normal saline. Later, an open-field test, a forced swim test, novel object recognition test, and an 8-arm radial maze test was conducted to assess the rats' anxiety, depression, and cognitive function. Results: There were different effects in the long- and short-term groups of energy drink administration. In the LT group, anxiety- and depressive-like behavior increased because of increased movement in the side corner and decrease of immobility time. Also, the time to explore novel objects decreased, and the number of correct responses was reduced, indicating a learning and memory function disorder. However, the ST group was not different from the control group. Conclusion: These results indicate that long-term consumption of energy drinks can increase anxiety-like, depression-like behavior, and this can lead to decrease in learning and memory functions. Thus, nurse and health care providers should understand the impact of energy drink consumption in adolescence to provide appropriate practices and education.

To find out the effect of commercially available energy drinks on tooth enamel erosion, analyzed pH, buffering capacity, and the content of some of the inorganic components selecting 4 energy drinks that has high affinity of the products currently being sold. In addition, by observing the degree of erosion before and after immersion in energy drink by surface microhardness and scanning electron microscope (SEM) the results were as follows: Acidity of energy drink 'Burn Intense' was the lowest as $2.78{\pm}0.01$ highest on distilled water as $6.475{\pm}0.01$. 'Burn Intense' buffering capacity was $3.48{\pm}0.155$ at pH 5.5, $1.88{\pm}0.15$ at pH 7.0 which is the highest, and 'Hot6' was $1.71{\pm}0.37$, $1.23{\pm}0.35$ on each of it showing the lowest points. Ca content on energy drink was the highest at 'Volt Energy' as ($77.21{\pm}2.70mg/kg$), the lowest at 'Hot6' as ($0.98{\pm}0.05mg/kg$). P content was the highest on 'Hot6'($1.34{\pm}0.05mg/kg$) and detected at 'Red Bull'. Enamel surface hardness variation of the energy drinks before and after immersion showed rapid decrease at 'Red Bull' ($66.65{\pm}35.60$), and 'Volt Energy' ($61.96{\pm}31.42$), 'Burn Intense' ($58.53{\pm}24.84$), 'Hot6' ($53.99{\pm}60.26$) was in order. Distilled water, the control group, showed significant difference with the experimental group (p<0.05). But there was no significant difference between energy drinks. At SEM observation and analysis, 'Burn Intense' was the most severe demineralization, 'Volt Energy', 'Hot6', 'Red Bull', distilled water was in order. In the above results, taken together there were no statistically differences between energy drinks but significant difference in comparison with distilled water. In addition, at SEM observation and analysis all energy drink caused dental erosion, especially 'Burn Intense', has the lowest acidity, was serious. Thus, it is believed to provide a variety of oral health education and information about energy drinks that can affect the erosion of the teeth so public have the right to be recognized and reasonable dental care.

The purpose of this study was to examine the relationship between high-intensity physical activity (work) and beverage intake frequency among Koreans. The data used in this study were obtained from the 8th Korea National Health and Nutrition Examination Survey(KNHANES) conducted in 2021. Statistical analyses, including χ²-test, and binary logistic regression, were conducted to examine group differences(p<0.05). It was found that 63.6% of the group consumed carbonated water once a week or less, and 68.6% consumed energy drinks once a week or less. These results indicated that carbonated water and energy drinks were more frequently consumed among individuals engaging in high-intensity physical activity(work), and that the majority of beverages were consumed once a week or less. Based on the findings of this study, it was hoped that the results can serve as a basis for the development of healthier alternative beverages to replace carbonated water and energy drinks during high-intensity physical activity(work). Additionally, it highlights the importance of exploring new approaches that promote health and the need for intervention programs aimed at improving health.

BACKGROUND/OBJECTIVES: Association between the consumption of sugar-sweetened beverages (SSBs) and obesity is universally a controversial issue. This study was undertaken to examine the beverage consumption pattern of Korean adolescents. SUBJECTS/METHODS: Data was collected from the 2016 Korea Youth Risk Behavior Survey involving 65,528 adolescent respondents. A list of the most frequently consumed beverages was analyzed, and the consumption frequency of carbonated beverages, SSBs, and energy drinks during the past seven-days was assessed. The main reasons for the adolescents to consume the beverages were also determined. RESULTS: The beverage preference of adolescents were carbonated beverages (31.0%), 'fruit and vegetable beverages (17.7%)', 'milk (13.6%)', and 'coffee (12.7%)'. Carbonated beverages and SSBs were consumed more than three times a week by 27.1% and 41.1% of the respondents, respectively. About 86.2% of adolescents did not take of any energy drinks during the last seven-days. Taste was the most common reason that adolescents considered when choosing a drink. Carbonated beverages consumed more frequently by boys than girls, and high school students drank coffee more frequently than middle school students. CONCLUSIONS: Boys had a higher preference for unhealthy beverages than girls, whereas consumption of high-caffeine drinks was greater amongst high-school students than middle school students.

This study was conducted to investigate the effect of fermented blackberry drinks (BD) on carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Male Sprague-Dawley rats were randomly divided into four groups with 6 rats per group: control, $CCl_4$, $CCl_4$ plus BD $3ml\;kg^{-1}$, and $CCl_4$ plus BD $6ml\;kg^{-1}$. We found that the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly increased and the activity of antioxidant enzyme glutathione peroxidase (GPx) in the liver was decreased in rats treated with $CCl_4$ alone when compared with the control group. However, the administration of BD attenuated the levels of serum AST and ALT in $CCl_4$-treated rats. Moreover, the administration of BD significantly increased the activity of GPx in $CCl_4$-treated rat livers. Taken together, these results suggest that BD could protect the liver from $CCl_4$-induced hepatic damage.

Surveys on the consumption of caffeinated beverages by high school students (n=886) were performed. Of the students, 97.0% consumed a variety of caffeinated beverages, including carbonated drinks (90.0%), processed milk and cocoa (79.0%), coffee (63.0), teas (52.1), energy drinks (16.4%) and nourishment drinks (15.5%). The frequency of intake per student was 8.2 times per week. Caffeine intake through the caffeinated beverages was 41.53 mg/day, which was accounted for by coffee (51.5%), carbonated drinks (19.6%), processed milk and cocoa (11.5%), teas (11.4%), energy drinks (5.0%) and nourishment drinks (1.1%). Students with high levels of stress, those who consumed snacks twice a day, and those who used a computer (or smart phone) for more than 3 hours per day showed significantly higher caffeine intake. The groups with high caffeine intake experienced heart palpitations, insomnia and pollakiuria. Students indicated that they consumed the caffeinated beverages for the taste (57.9%), waking up (18.0%), thirst (13.2%), etc. (10.9%). They tended to consume drinks with a high content of caffeine to sleep less. In addition, they rarely checked the label, and showed a lack of awareness of the caffeine contents in the beverages, which calls for education.

Purpose: The purpose of this study is to examine the association between consuming high-caffeine energy drinks and suicidal ideation in Korean adolescents. Methods: This study used data drawn from the 2015 Korea Youth Risk Behavior Web_Based Survey. The data of 66,068 students in total (33,374 middle school students and 32,694 high school students) were included in the analysis. The $x^2$ test, univariate and multivariate logistic regressions were conducted with the use of SAS 9.3. Results: Adjusted for the variables associated with suicidal ideation, multivariate logistic regression revealed that consuming highly caffeinated energy drinks had a significant effect on suicidal ideation (middle school students, 1~2 times per week: OR=1.24, 3~4 times per week: OR=1.88, 5~6 times per week: OR=2.20, everyday: OR=2.66, high school students, 1~2 times per week: OR=1.26, 3~4 times per week: OR=1.84, 5~6 times per week: OR=2.42, everyday: OR=3.89). Conclusion: This study strongly suggests adolescents be provided with health education and information about consuming an adequate amount of high-caffeine energy drink and the drink's side effects. In addition, regulations and polices on high-caffeine drink intake should be implemented.

A survey was carried out regarding university students' recognition of high-caffeine energy drinks in an effort to identify and improve problems as well as provide basic data. Most of the subjects had previous experience of energy drink consumption. Studies showed that most students consumed energy drinks when studying. Regarding frequency of energy drink consumption, most students' responded "1~6 times a year"; female students showed lower frequency of energy drink consumption than male students. Both male and female students used convenience stores to purchase energy drinks. In most cases, students became aware of energy drinks through advertisements on TV, radio, newspapers, and magazines. The most important factor affecting their energy drink purchase and consumption status was taste. The most frequent adverse effect they experienced after drinking an energy drink was unusual heart-pounding, whereas the biggest problem caused by energy drink consumption was addiction. This study indicates that students should have a better understanding of the problems associated with excessive and prolonged high-caffeine intake. In addition, instructions for proper purchasing and consumption of high-caffeine energy drinks should be provided as well as education and campaigns concerning symptoms caused by high-caffeine energy drink consumption so that students may refrain from excessive consumption. Further, civil organizations and the government need to devise effective measures for proper regulation of high-caffeine energy drink consumption.

Purposes: The purpose of this study was to examine the association between risk behaviors and smoking in Korean adolescents. Methods: This study used data from online survey of youth health behavior in 2017. Data from a total of 54,411 people (27,139 male, 27,272 female) were included in the analysis. chi-square test, simple logistic regression, multiple logistic regression were performed using SAS 9.4. Findings: Multiple logistic regression analysis showed that risk behaviors such as drinking alcohol experience, sexual experience, drug use experience and high caffeine energy drinks intake experience had a significant effect on smoking. Adolescents with drinking experience were more likely to smoking than those who had no experience(OR=8.58, 95% CI: 7.67~9.60). Adolescents with sexual experience were more likely to smoking than those who had no experience(OR=4.47, 95% CI: 3.91~5.11). Adolescents with drug use experience were more likely to smoking than those who had no experience(OR=2.32, 95% CI: 1.63~3.32). Also, adolescents with high-caffeine energy drinks intake experience were more likely to smoking than those who had no experience(OR=1.37, 95% CI: 1.23~1.53). Practical Implications: All the risk behaviors were significantly associated with smoking rates. Results of this study suggest that physicians and health workers in medical institutions and health centers should simultaneously serve education and consultation for the smoking cessation as well as for the prevention of risk behaviors.
