This study examined the factors affecting the underweight of Korean adolescents using data from Korea youth risk behavior web-based survey, which are national health statistics. This is a second data analysis study using the 13th Korea youth risk behavior web-based survey. The subjects were 48,242 adolescents who range from the first-year middle school students to the third-year high school students. The measurement variables were classified into demographic, physical activity, dietary, and mental health characteristics. The collected data were analyzed by logistic regression analysis. The factors affecting the underweight of Korean adolescents were sex, school type, academic performance, economic level, physical activities, weight control efforts, ramen intake, confectionary intake, stress, and subjective sleep fulfillment rate. Based on the results of this study, we need to search for the measures to help underweight adolescents recover their proper weight.

Objectives: The aim of this study was to measure secular trends in health risk behaviors among middle and high school students in Korea between 2005 and 2009 by using data from the Korea Youth Risk Behavior Web-based Survey(KYRBS). Methods: The analyses were performed using data from the 2005, 2006, 2007, 2008, and 2009 KYRBS, which included a nationally representative sample of middle and high school students. A total of 34 health behavior indices were used for the assessment of secular trends in health risk behaviors. Logistic regression models were used to identify statistically significant secular trends in health risk behaviors, after adjusting for gender and grade. Linear and higher-order time variables were simultaneously entered into the statistical models. Results: There was evidence of small, but statistically significant increasing or decreasing trends in certain health risk behaviors. Secular trends in health risk behaviors varied by gender. Conclusions: This study indicates that between 2005 and 2009, changes in health risk behaviors among Korean adolescents were generally small, but represented statistically significant increases or decreases. Further research should explore why certain health risk behaviors are increasing or decreasing and what types of interventions are most effective.

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.

In this study, in an attempt to prevent depression and improve their quality of life, we investigated the relationship between the occurrence rate of depression among high school students. We used the data from the 2011-2 online census on youth health behavior conducted by the Ministry of Disease Control. There were 37,261 male students along with 36,797 female students for a total of 74,058 subjects. The rate of depression occurrence was 29.2% for male students and 39.6% for female students indicating that female students are having more depression than male students. As a result of the study, it was discovered that the male subjects felt 6.04 times more depression and the female subjects felt 6.98 times more depression as they encountered more stress. The males had 1.42 times more depression and the females had 1.60 times more depression when they had the experience of smoking. The male subjects had 1.37 times more depression and the female subjects had 1.41 times more depression when they had the experience of drinking. The males who joined in on physical activities for more than four days and those who joined in them for one to three days had 1.34 times and 1.16 times more depression respectively. The females who had physical activities for more than four days and those who had them for one to three days had 1.42 times and 1.28 times more depression respectively. As a result this study showed that there are correlations between variables relating to healthy behavior and the prevalence of depression.

The purpose of this study was to analyze the effects of adolescents' Internet Usage Levels on their oral symptoms using the data from 60,040 students in the 14th Korea Youth Risk Behavior Web-Based Survey in 2018. The logistic regression for the effects of Internet Usage Level on the oral symptoms were analyzed using a logistic regression method. Symptoms of toothache when eating and throbbing symptoms, and gum pain symptoms showed high levels of stress, and high awareness of pain when lower daily frequency of tooth-brushing. In addition, the less time spent on the Internet, the more subjective health awareness, the higher sleep satisfaction, the less smoking and drinking experience, Results were significantly lower. In conclusion, health education that mitigates adolescents' excessive use of the Internet is believed to enable proper health practices and is intended to help develop health education programs that can prevent such oral symptoms.

Objectives: The aim of this study was to verify relationships between light- and heavy alcohol drinking and health-risk behaviors such as smoking, inappropriate weight control, physical inactivity, and sexual activity among adolescents. Methods: The data of 68,043 adolescents in middle- and high school collected from the Korea Youth Risk Behavior Web-based Survey in 2015 were analyzed. For statistical analysis, logistic regression model was used. Results: The rate of heavy alcohol drinking increased with increasing age up to 21.5% among boys and 13.9% among girls. Among boys, heavy alcohol drinkers were at a higher risk of smoking (adjusted odds ratios [OR]=3.3, 95% confidence interval [CI]=2.8-3.8), inappropriate weight control (OR=1.7; 95% CI=1.4-2.1), having sexual intercourse (OR=3.6; 95% CI=3.0-4.2) than light drinkers. Multiple health-risk behaviors of smoking, inappropriate weight control and sexual intercourse also increased in accordance with the severity of drinking alcohol beverage compared to non-drinker. Physical inactivity was decreased among heavy drinkers compared to light drinkers (OR=0.8; 95% CI=0.7-0.9 for inactivity of moderate exercise). Similar results were observed among girls. Conclusions: Alcohol drinking especially heavy alcohol drinking among adolescents is related to other risky behaviors including smoking, inappropriate weight control, and sexual activity. To prevent health problems in adolescents, it is necessary to adopt a combined approach regarding heavy drinking and health-risk behaviors.

Purpose: The purpose of this study was to develop a system dynamics model for adolescent obesity in Korea that could be used for obesity policy analysis. Methods: On the basis of the casual loop diagram, a model was developed by converting to stock and flow diagram. The Vensim DSS 5.0 program was used in the model development. We simulated method of moments to the calibration of this model with data from The Korea Youth Risk Behavior Web-based Survey 2005 to 2013. We ran the scenario simulation. Results: This model can be used to understand the current adolescent obesity rate, predict the future obesity rate, and be utilized as a tool for controlling the risk factors. The results of the model simulation match well with the data. It was identified that a proper model, able to predict obesity probability, was established. Conclusion: These results of stock and flow diagram modeling in adolescent obesity can be helpful in development of obesity by policy planners and other stakeholders to better anticipate the multiple effects of interventions in both the short and the long term. In the future we suggest the development of an expanded model based on this adolescent obesity model.

Purpose: The purpose of the study was to investigate the effect of loneliness on habitual drug use in Korean adolescents. Methods: The study was designed as a cross-sectional study. Using statistics from the 16th (2020) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. A total 54,948 adolescents were included in the analysis. Results: Adolescents were more likely to engage in habitual drug use when they were lonely than when they were not (OR: 1.55, 95% CI: 1.20~2.02). As for sociodemographic characteristics, gender, academic achievement, and living with family were factors influencing habitual drug use. As for health behavior characteristics, perceived stress, depression, current drinking, violence, sexual intercourse, and perceived health were identified as factors affecting habitual drug use. Conclusion: Provision of education that includes loneliness as a factor, which was not previously considered important in school education for preventing habitual drug use of adolescents, should be considered.
