This study demonstrates the association between total sleep duration of adolescents, and its effects on their physical and mental health. Chi-square test and the multiple logistic regression model were applied to analyze the data collected in 2018 by the Korean Youth Health Behavior Survey (n = 52,928), conducted by the Korea Centers for Disease Control & Prevention. Our analysis indicates increased suicidal ideation with insufficient total sleep duration as per the recommended amount and grade (OR: 1.17, 95% CI: 1.06-1.29, p-value: 0.00]. Especially, insufficient sleep among adolescent girls significantly increases the risk of suicidal thoughts (OR: 1.22, 95% CI: 1.06-1.41, p-value: 0.01). Sufficient sleep showed reduced risk of suicidal ideation among boys (OR: 0.83, 95% CI: 0.71-0.96, p-value: 0.02). We propose that to reduce the risk of suicide among teenagers, policy considerations are required to ensure sufficient sleep.

The purpose of the study were to analyze the patterns of adolescent suicide attempts, and to explore the effects of personal psychology (subjective depression, subjective stress), health status (BMI, subjective health perception), and subjective academic performance on the types of youth suicide attempts. For this research, data of 'The 15th Korea Youth Risk Behavior Survey' were analyzed employing a hierarchical logistic regression analysis. The findings are as follows. First, out of 1,731 youth suicide attempts 156 (9%) were impulsive and 1,575 (91%) were planned. Girls(67.3%) attempted suicide more than boys (32.5%), and middle school students (62%) attempted suicide more than high school students (38%). Second, the variables that significantly affect suicide attempt types were subjective depression, subjective stress, and subjective health perception, after controlling for gender, grade level, school type, and SES. The rate of planned suicide attempts was higher among those who experienced depression than among those who did not. In the case of subjective stress, adolescents who felt stressed were likely to commit planned suicide attempts. Those who attempted impulsive suicide showed 1.32 times higher subjective health perception scores than those who attempted planned suicide, indicating adolescents who perceived they were not healthy were more likely to attempt planned suicide. BMI and subjective academic performance did not have a significant effect on the types of youth suicide attempts. These findings suggested the necessity of systematic intervention in Home Economics classes or extra-curricular programs, to prevent potential youth suicide attempts.

Objectives: The purpose of this study was to determine the factors influencing oral health education of adolescents from multi-cultural families. Methods: The subjects were 711 multi-cultural adolescents from the 15th(2019) Korean youth risk behavior web-based survey. Multi-cultural adolescents were defind as the children of marriage migrant women. The collected data was analyzed using the chi-squared test and logistic regression; SPSS versin 18.0 was used. Results: Middle-school adolescents received more oral health education than their high-school counterparts. The adolescents with once-daily and twice-daily teeth brushing behaviors were 0.475 (p<0.05) and 0.784 times less those with thrice-daily behavior, respectively. Adolescents who received oral health education also experienced dental care 1.644 times more than their counterparts(p<0.05). Conclusions: The promotion of oral health among multicultural families and further education through the establishment of school oral health education programs are required.

The purpose of this study was to analyze the dietary habits and health risk behaviors of adolescents who experienced part-time job. For this study raw data from the 13th Youth Health Behavior Online Survey (2017) was examined. Dietary habits and health risk behaviors for 62,823 adolescents were analyzed according to the experience of part-time job. Collected data were analyzed with the SPSS 24.0 program using descriptive statistics and logistic regression analysis, to which the complex sample design was applied. The odds ratio of no fruit intake in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 1.20 (CI: 1.10-1.31). The odds ratio of fastfood intake in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 1.28 (CI: 1.19-1.38). The odds ratio of present smoking in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 3.48 (CI: 3.17-3.84). The odds ratio of present drinking was 3.36 (CI: 3.14-3.96). The odds ratio of high caffeine intake was 1.11 (CI: 1.04-1.19). The odds ratio of high caffeine intake was 2.29 (CI: 2.06-2.55). In developing health education programs for adolescents, it is necessary to include dietary habits and health risk behavior according to part-time experience.

This study used the raw data of the 15th (2019) Korean Youth Health Risk Behavior Survey to investigate the risk factors of the health-risk behaviors of Korean multicultural adolescents on the subjective oral symptoms. The scope of the multicultural family was limited to children of immigrant women's families married to Korean men and immigrant male families married to Korean women, and 572 were selected as the final study subjects. The sociodemographic variables were surveyed as gender, grade, economic level, and school performance. The health risk behaviors included drinking, smoking, medication, stress, sleep satisfaction, suicidal thoughts, depression, and brushing before bedtime. The oral symptoms examined were toothache, gum pain, and halitosis. As a result, toothache was related to drinking, toothbrushing before sleep, stress, sleep satisfaction, suicidal thoughts, and depression. Gum pain was associated with drug use, sleep satisfaction, suicidal thoughts, and depression. Halitosis was associated with medication, brushing before sleep, stress, suicidal thoughts, and depression. In terms of health risk factors, drinking, stress, and sleep satisfaction were risk factors for toothache. Smoking, sleep satisfaction, and suicidal thoughts were risk factors for gum pain. The presence of toothbrushing and stress were risk factors for halitosis. In conclusion, a policy system is needed to support oral health education programs nationally at times, such as after-school activities or club activities, to promote oral health for teenagers.

This study was conducted to identify the impact of adolescents' dietary behavior on their stress perception and provide basic data for education programs linked to customized nutrition education by gender. In this study, the 2019 Korea Youth Risk Behavior Web-based Survey was used, and a total of 57,303 middle·high school students were selected. Controlling adolescents' age, school record, economic status, residence type, subjective health and body type perception, and the dietary life variables designed with breakfast, fresh foods(fruit, vegetables, milk, water), processed foods(carbonate beverage, energy beverage, sweet beverage, fast food) were analyzed to have an effects on the stress recognition of adolescents. Breakfast had a negative(-) effect on stress perception in all genders of adolescents, and in the case of fresh food, water for boys and fruit for girls had the highest negative(-) effect on stress perception, and in the case of processed foods, energy drink was the dietary factor that had the highest positive(+) effect on adolescents' stress perception. These results suggest that it is necessary to develop a dietary education program tailored to the gender of adolescents to improve their stress perception, and to provide continuous guidance to form a healthy diet.

Purpose: The purpose of the study was to investigate health behavior changes in Korean adolescents before and during the COVID-19 pandemic. Methods: A descriptive cross-sectional design was employed. Data were obtained from the 15~16th (2019~2020) Korea Youth Risk Behavior Web-based Survey. Overall, the data of 112,251 students, 57,303 before the COVID pandemic and 54,948 during the pandemic, were included. The data were analyzed using rao-scott 𝝌²-test, t-test, ANCOVA and logistic regression analysis. Results: While sitting time for study decreased, sitting time for leisure increased in the 2020 group compared to the 2019 group. The 2020 group was more likely to skip breakfast and have a higher BMI than the 2019 group. The 2020 group was less likely to consume fruit and engage in moderate and vigorous physical activities than the 2019 group. The 2020 group was less likely to engage in CC, EC, and HTP current smoking and be exposed to secondhand smoke at home, school, and public places than the 2019 group. The 2020 group was more likely to be satisfied with sleep, but less likely to experience stress, depression, suicidal ideation, suicidal plans, and suicidal attempts than the 2019 group. Conclusion: It is necessary to reduce sedentary time, encourage physical activities, manage smoking and drinking rates continuously, and establish a network system to prevent psychological loneliness and isolation for adolescents, which requires participation of experts from the community as a whole.

The purpose of this study was to grasp the influence of mental health upon the lifelong drinking experience in adolescents of non-capital area and capital area through using the 2019 Youth Health Behavior Survey Data. The research subjects included total 57,303 adolescents who participated in the survey among 60,100 adolescents at totally 800 schools with 400 middle schools and 400 high schools. Out of these, 29,384 middle school students and 27,919 high school students were selected. As a result of the research, the mental health that has significant influence upon the lifelong drinking and smoking experience in case of non-capital area appeared to be significant in the perceived subjective health (p<.01), cognitive stress(p<.001), relief from fatigue(p<.001), sadness & despair experience(p<.001), suicide ideation(p<.001), suicide plan(p<.01), and suicide attempt(p<.001). In case of capital area, the mental health of having a significant impact on the lifelong drinking and smoking experience was indicated to be significant in cognitive stress(p<.01), relief from fatigue(p<.001), sadness & despair experience(p<.001), suicide ideation(p<.001), and suicide attempt(p<.001). Based on this outcome, adolescents' drinking problem has influence upon mental health characteristic. Hence, an effort is needed for developing the intervention & education program aiming at the more effective youth drinking prevention through establishing direction and revaluing education program in consideration of mental health factors by region in adolescents of capital area and non-capital area.

This study examined the changes of the dietary behaviors of Korean adolescents during the COVID-19 pandemic. Data were obtained from 227,139 students aged 12-18 who participated in the Korean Youth Risk Behavior Survey from 2018 to 2021. The participants were divided into two groups: 117,343 students from the 2018-2019 survey and 109,796 from the 2020-2021 survey. Multiple regression analyses were used to calculate the adjusted odds ratio (AOR) for dietary behavior changes between the two groups. The AOR for consuming carbonated beverages among those who consumed three or more times per week compared to those who did not consume carbonated beverages at all was 0.81 (95% confidence interval [CI]: 0.78-0.84), which significantly decreased during the COVID-19 pandemic (p<0.001). Similarly, the AOR for consuming sweetened beverages between those with three or more times and not at all per week was 0.69 (95% CI: 0.67-0.72) (p<0.001). In contrast, there was a significant increase in the AORs for consuming fast food (AOR: 1.15, 95% CI: 1.11-1.20) and skipping breakfast more than three times per week (AOR: 1.23, 95% CI: 1.20-1.26) during the same period. Fruit intake decreased during the COVID-19 pandemic (AOR: 1.26, 95% CI: 1.21-1.31). In conclusion, the COVID-19 pandemic had both positive and negative impacts on the dietary habits of Korean adolescents.
