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: 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.

Background: This study investigated the health behaviors of North Korean, multicultural, and Korean family adolescents in Korea. Methods: The study subjects were from the Korea youth risk behavior web-based survey (2011-2013) dataset. We identified 1,954 multicultural family adolescents and twice as many Korean family adolescents. Frequency analysis was used to assess nativity and nationality of the parents, and the chi-square test was used to compare the general characteristics and health behavior of the multicultural and Korean families. Conditional multiple logistic regression was used to compare health behavior between multicultural and Korean families. Results: Of the 5,862 multicultural and Korean family adolescents, current smoking in North Korean family adolescents was higher than Korean family adolescents (adjusted odds ratio [aOR], 2.32; 95% confidence interval [CI], 1.60-3.35) after adjusting for sex, school year, perceived school record, family structure, father's education, mother's education, perceived economic status, place of residence, and survey year. A high drinking rate was significantly greater in North Korean family adolescents compared to Korean family adolescents (aOR, 2.94; 95% CI, 1.89-4.57). Odds ratios for sufficient physical activity of vigorous intensity (aOR, 1.82; 95% CI, 1.31-2.54) were significantly higher in North Korean family adolescents than in Korean family adolescents. Fast food intake (aOR, 1.96; 95% CI, 1.34-2.86) was significantly higher in North Korean family adolescents compared to Korean family adolescents. Conclusion: There were differences in health behavior between North Korean, multicultural, and Korean family adolescents. Further studies are needed to investigate the factors associated with these differences.

This study was conducted to investigate the factors related to smoking and smoking differences among adolescents who have experienced smoking using data from the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data used in this study were from 5,347 middle and high school students who had cigarette smoking and electronic cigarette smoking experience among 68,043 respondents to the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data were evaluated by frequency analysis, the ${\chi}^2$ test and logistic regression analysis using weighted composite sample analysis. Overall 20% of the total smoking adolescents were dual users and 85.6% of the users of electronic cigarettes used nicotine. The results from multinomial regressions show that: male students (OR 1.63; 95% CI 1.15-2.31), living in the metropolitan area (OR 1.76; 95% CI 1.32-2.33), an average consumption of fast food of once or twice a day (OR 2.48; 95% CI 1.33-4.64), first started smoking during high school (OR 0.76; 95% CI 0.58-0.98), having experience with passive smoking (OR 1.24; 95% CI 1.07-1.44), experience drinking alcohol (OR 2.03; 95% CI 1.65-2.48) and those with higher weekly allowances were more likely to be at risk than dual users. This study provides basic data regarding the dual use of electronic cigarettes and cigarettes by adolescents. The results presented herein will facilitate development of a smoking cessation program and policy.

Purpose: This cross-sectional study was conducted to investigate the prevalence of health risk behaviors by gender and grade and to examine the correlation between health risk behaviors and self-efficacy in early adolescents. Method: The sample of this study consisted of 1.693 early adolescents recruited from 7 middle schools in S-Gu, Seoul, Korea. Health risk behaviors were measured by the Youth Risk Behavior Surveillance Survey (YRBS). Self-Efficacy was assessed by General Self-Efficacy (GSE). Results: About a third of the subjects had experience in drinking behavior about 19.4% in cigarette smoking (including cases of just one or two puffs), 25.9% in physical fight, 29.1% in thought about killing themselves (suicide-related behavior), 1.5% in drug. More than a half (60.5%) experienced at least one health risk behavior. Female students were more likely to report drinking experience and suicide-related experience. Health risk behaviors were not significantly correlated with self-efficacy in early adolescents. Conclusions: Many early adolescents had experience in health risk behaviors in the past. The findings of this research suggest the necessity of intensive prevention programs in middle school to motivate and prepare students to avoid these behaviors. In addition, these results may help health professionals plan appropriate screening and counselling for health problems in early adolescents.

Purpose: This study was done to construct and test a structural model to explain health risk behavior of late adolescents. Methods: Data for this study were secondary data from the 2010 Korea Adolescent Health Survey based and 3,675 high school students who participated. Data were analyzed using SPSS 18.0 and AMOS 19.0 programs. Results: After 7 lines were removed, fitness statistics for the hypothetical model were appropriate (${\chi}^2$=559.13, p<.001, GFI=.98, SRMR=.03, RMSEA=.04, NFI=.88, IFI=.90, CFI=.90, TLI=.86, AIC=671.13). The result showed that drinking-smoking is directly affected by 5 variables (32.5%), obesity is directly affected by 2 variables (0.7%), lack of physical activity is directly affected by 5 variables (22.2%), skipping of breakfast is directly affected by 3 variables (11.9%), improper sleep is directly affected by 3 variables (7.5%), and psychological adaptation is directly affected by 4 variables (26.8%). Conclusion: The results of this study, indicate that late adolescents' health risk behavior is affected by many factors with complicate correlations suggesting further study compare youth health risk behaviors in a variety of environments.

Objectives: Anxiety disorders are the most common psychiatric disorders in adolescents and seem to occur the earliest among all forms of psychopathology. The aim of this study was to investigate the association of anxiety severity with health risk behaviors and mental health in adolescents. Methods: Data from the 2020 Korean Youth Risk Behavior Web-Based Survey were analyzed. A total of 54948 adolescents responded to the 7-item Generalized Anxiety Disorder Scale (GAD-7) for the assessment of their anxiety severity as well as to the mental health and health risk behavior survey. Logistic regression analysis, t tests, and variance analysis of a complex sample general linear model were used to examine the association of anxiety severity with health behaviors and mental health. Results: After statistical adjustment for sociodemographic characteristics, the subjects in the severe anxiety group were significantly more likely to be current smokers (odds ratio [OR]: 2.08, 95% confidence interval [CI]: 1.72-2.50), current drinkers (OR: 1.91, 95% CI: 1.67-2.19), experience habitual substance use (OR: 10.89, 95% CI: 8.22-14.42), have sexual intercourse (OR: 2.10, 95% CI: 1.76-2.51), and have unprotected intercourse (OR: 2.21, 95% CI: 1.67-2.92) than those in the normal group. Anxiety severity negatively correlated with sleep satisfaction and happiness, but positively correlated with stress perception, loneliness, depressive symptoms, and suicidality. Conclusion: Adolescent anxiety is associated with health risk behaviors and poor mental health. Thus, early screening and intervention for anxiety in adolescents could contribute to the management and coping of youth health risk behaviors in the community.

Purpose: The purpose of this study was to investigate factors influencing lifetime smoking and current smoking among adolescents in South Korea. Methods: Hierarchical logistic regression was conducted based on complex sample analysis using statistics from the 10th (2014) Korea Youth Risk Behavior Web-Based Survey. The study sample comprised 72,060 adolescents aged 12 to 18. Results: The significant factors influencing adolescent lifetime smoking were female gender, older age, higher stress, higher weekly allowance, lower economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. The significant factors influencing adolescent current smoking were female gender, older age, higher stress, higher weekly allowance, both higher and lower economic status compared to middle economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. Conclusion: Factors identified in this study need to be considered in programs directed at prevention of adolescent smoking and smoking cessation programs, as well as policies.
