Purpose: The purpose of this study was to examine effects of school-based alcohol prevention programs on drinking statuses of adolescents. Methods: The findings of this study was based on the data obtained from the '2015 11th Korea Youth Risk Behavior Web-based Survey. The number of study subjects were 68,043. Results: It was figured that 35.6% of the study subjects had experienced school-based alcohol prevention programs within the last 12 months. As the students got older, the chances to participate in the programs decreased (p<.01). For both middle and high school students, current drinking rates for the educated was lower than those of the uneducated students(6.6% vs 8.0%; 22.2% vs 25.9%) and it was statistically significant. A similar pattern was found for high-risk drinking rates. Those educated showed lower rates than the uneducated with statistical significance of p<.001. In addition, the educated had lower problem drinking rate than the uneducated for both middle (p<.05) and high school students (p<.001). The results of logistic regression analysis showed that school-based alcohol prevention programs had statistically significant effect on current drinking status of adolescents (p<.05). However, it had significant effect only on high-risk drinking status of high school students (p<.05) and had no effect on problem drinking. Conclusion: This study addressed effectiveness of school-based adolescent alcohol prevention programs and that it is important to develop means to implement school health education.

Purpose: Suicide among adolescents is a serious problem worldwide, and especially, the suicide rate of teenagers is increasing rapidly in South Korea. This study was conducted to investigate the factors affecting the respective suicidal behavior in terms of home-environment characteristics, health behavior characteristics, and psychological health characteristics in Korean adolescents. Methods: The data of the Web-based Survey of the Youth Risk Behavior from 2015 to 2017 collected by the Korea Centers for Disease Control and Prevention (KCDC) was analyzed using multivariable logistic regression analysis. Results: The influential factors by depression and suicidal behavior (suicidal ideation (SI), suicidal plan (SP), and suicidal attempt (SA)) were female(adjusted odds ratios [aOR], 1.45, 1.69, 1.30, 2.19), age (aOR 1.03, 0.98, 0.97, 0.90), no family members (aOR 1.21, 1.36, 2.11, 2.32), living with only the father (aOR 1.05, 1.06, 1.07, 1.11), high economic status (aOR 1.15, 1.22, 1.34, 1.46), residence in relatives' home (aOR 1.6, 1.36, 2.34, 1.97), drinking experience (aOR 1.35, 1.47, 1.57, 1.76), smoking experience (aOR 1.28, 1.30, 1.31, 1.94), hospital treatment experience due to violence (aOR 2.18, 3.33, 6.24, 8.40), bad health status (aOR 1.23, 1.48, 2.00, 2.15), unhappiness (aOR 2.49, 6.14, 6.72, 8.89), and a lot of stress (aOR 6.05, 10.40, 4.86, 5.52). Conclusion: The suicidal behavior risk screening and prevention program for adolescents should be developed considering the subjective happiness and hospital treatment experience status due to violence that affects suicidal behavior.

Objectives: Cigarette smoking prevalence among adolescent males in rural areas of Korea has increased in recent years. The aim of this study was to explore the factors related to increasing trends in cigarette smoking among adolescent males living in rural areas. Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey from 2006 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Multiple logistic regression models were used to explore the factors affecting cigarette smoking. We evaluated the linear time trends in the prevalence of factors that were related to current smoking status and the linear time trends in cigarette smoking in groups stratified by the exposure to each factor using logistic regression models. Finally, we examined the contributions of the factors to the time trends in cigarette smoking by adjusting for each of those factors in the baseline regression models and changes in the adjusted odds ratio by survey year. Results: A statistically significant increasing trend in smoking was observed after adjusting for the factors affecting cigarette smoking. Significant factors related to cigarette use were perceived stress, experience with depression, current alcohol drinking, exposure to secondhand smoke, and academic performance. The factor related to increasing trends in cigarette smoking was academic performance. Conclusions: Stress about academic performance is an important factor affecting the increase in cigarette smoking among adolescent males in a rural area of Korea.

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 compare the risk of being underweight between multicultural and Korean-origin adolescents. Methods: This study used the Korea Youth Risk Behavior Web-Based Survey data of 2016. A total of 46,457 underweight and normal-weight adolescents were included. General characteristics, health status and health behavior variables, and weight related variables were included. Weighted percentage and means were used to describe the sample. Simple and multiple logistic regressions were conducted using SAS 9.2. Results: From the simple and multiple logistic regression, multicultural adolescents showed a higher risk of being underweight (OR: 1.63, 95% CI: 1.20~2.20; AOR: 1.51, 95% CI: 1.01~2.27) than Korean-origin adolescents. Among the covariates, being female (AOR: 1.90, 95% CI: 1.72~2.10), being older (AOR: 1.18, 95% CI: 1.15~1.22), having poor self-health perception (AOR: 1.56, 95% CI: 1.24~1.82), having longer hours of sleep (AOR: 1.12, 95% CI: 1.09~1.16), having fewer days of exercise (AOR: 0.94, 95% CI: 0.91~0.96), and doing vigorous exercise less (AOR: 0.78, 95% CI: 0.68~0.89) showed a higher risk of being underweight. Self-rated health and effort to control weight were also significantly related to being underweight. Conclusion: Since multicultural adolescents are vulnerable to being underweight, it is necessary to develop intervention programs to reduce the number of underweight multicultural adolescents.

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.

Purpose: The objective of this study was to develop a predictive model for the sexual experiences of adolescents using the random forest method and to identify the "variable importance." Methods: The study utilized data from the 2019 to 2021 Korea Youth Risk Behavior Web-based Survey, which included 86,595 man and 80,504 woman participants. The number of independent variables stood at 44. SPSS was used to conduct Rao-Scott χ² tests and complex sample t-tests. Modeling was performed using the random forest algorithm in Python. Performance evaluation of each model included assessments of precision, recall, F1-score, receiver operating characteristics curve, and area under the curve calculations derived from the confusion matrix. Results: The prevalence of sexual experiences initially decreased during the COVID-19 pandemic, but later increased. "Variable importance" for predicting sexual experiences, ranked in the top six, included week and weekday sedentary time and internet usage time, followed by ease of cigarette purchase, age at first alcohol consumption, smoking initiation, breakfast consumption, and difficulty purchasing alcohol. Conclusion: Education and support programs for promoting adolescent sexual health, based on the top-ranking important variables, should be integrated with health behavior intervention programs addressing internet usage, smoking, and alcohol consumption. We recommend active utilization of the random forest analysis method to develop high-performance predictive models for effective disease prevention, treatment, and nursing care.

Purpose: The purpose of this study is to identify factors related to hand washing practice among adolescents before and after the outbreak of the COVID-19 pandemic. Methods: The study was conducted using data from the 15th~16th (2019~2020) Korea Youth Risk Behavior Web-based Survey, and the subjects of the study were 57,303 and 54,948 people who participated in the 2019 and 2020 study, respectively. The data were analyzed with frequency test, rao-scott 𝑥² test and multiple logistic regression analysis using SPSS 27.0. Results: Changes in the hand washing practice rate were observed before and after the COVID-19 pandemic in all five behaviors; before eating in school, after using the toilet in school, before eating at home, after using the toilet at home, and after returning home. The study found that the hand washing practice rate increased by 1.21-2.43 times after the COVID-19 pandemic. In addition, as a result of logistic regression analysis, the hand washing practice rate before and after the COVID-19 pandemic was related to gender, region, school grade, school type, economic status, health status, and personal hygiene education experience. Conclusion: This study confirmed the importance of hand washing education to improve the hand washing practice rate in adolescents. It is necessary to develop and apply an effective youth hand washing education program in consideration of various variables that appeared as significant factors influencing the hand washing practice rate before and after the COVID-19 pandemic.

Objectives: Adolescent suicide is a global problem. This study aimed to identify associations between parental marital status and suicidal behavior. Methods: This study analyzed 118 715 middle and high school students from the 13th and 14th Korea Youth Risk Behavior Web-based Survey. The odds ratios (ORs) of suicidal ideation, planning, and attempts were calculated based on parental marital status, living situation, and socioeconomic factors. The data were analyzed using multiple logistic regression. Results: When compared to those living with 2 married biological parents, the ORs of suicidal ideation among adolescents living with either remarried or no parents were 1.34 (95% confidence interval [CI], 1.17 to 1.53) and 1.36 (95% CI, 1.11 to 1.66), respectively. For suicidal planning, the OR of those living with 1 remarried biological parent was 1.24 (95% CI, 1.01 to 1.52), and that of those living without parents was 1.28 (95% CI, 0.95 to 1.73), when compared to adolescents living with 2 married biological parents. For suicide attempts, when compared to adolescents with 2 married biological parents, the OR of those living with 1 remarried biological parent was 1.48 (95% CI, 1.17 to 1.87) and that of those living without parents was 2.02 (95% CI, 1.44 to 2.83). For adolescents living with 1 remarried biological parent, suicidal behavior was strongly associated with having no siblings and were weakly associated with not living with grandparents. Conclusions: Suicidal behavior among adolescents was associated with the remarriage and loss of parents. Therefore, special attention and interventions are needed for adolescents in those situations.
