This study compared actual weight with perceived weight, described the prevalence of unhealthy weight control behavior, determined the differences in psychological and personal variables between participants that reported unhealthy weight control behavior and those who did not, and examined the relationship of eating habits to unhealthy weight control behavior for Korean adolescents. The study population consisted of a nationally representative sample of middle and high school students who completed the Fifth Korea Youth Risk Behavior Web-based Survey (KYRBWS): Fifth in 2009. Among the 75,066 participants of KYRBWS, 35,473 (n = 18,851 girls and 16,622 boys) were eligible for a research focused on unhealthy weight control behavior. The results of this research were as follows: First, there were considerable discrepancies (45.1% of girls and 32.8% of boys) between the perceived weight and the actual weight. Second, overall, unhealthy weight control behavior was more prevalent in girls and fasting was the most commonly reported behavior. Third, participants that reported unhealthy weight control behavior scored significantly lower on scaled measures of happiness, health, academic achievement, and economic status; in addition, they scored higher on stress measures. Fourth, girls and boys shared common protective factors of having breakfast and vegetables more often, perceiving their weight as underweight rather than overweight, and having a correct weight conception. Protective factors unique to girls were having lunch and dinner more often. Girls and boys shared common risk factors of the consumption of soda, fast food, instant noodles, and snacks more often, while consumption of fruit more often was a risk factor only for girls. The improvement of protective factors and minimization of risk factors through Home Economics classes (and other classes relevant to health) may mitigate unhealthy weight control behavior of adolescents.

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 this study was to determine the factors that influence suicidal ideation and suicidal attempts of adolescents who had been bullied. Methods: This study used data extracted from Korea Youth Risk Behavior Web-Based Survey of 2014. The data of 1,926 adolescents, in total, who had experienced violence were included in the analysis, The analysis was done using SPSS/WIN. Results: The adolescents with an experience of being bullied were more likely to engage in suicidal ideation and suicidal attempts than the average teenagers in Korea. In addition, suicidal thoughts were affected by gender, experience of habitual drug use, subjective happiness, as well as sadness and despair. Suicidal attempts were influenced by gender, grade, smoking experience, experience of habitual drug use, size of the city of residence, subjective happiness, sadness and hopelessness, existence of people to get counseling, and habit of walking for 10 minutes every day. Conclusion: More attention should be given to the suicidal risk of adolescents having experienced violence. Further studies are required to develop an intervention program for suicide prevention targeting adolescents who have experienced violence and assess the program's effectiveness.

Purpose: This study was conducted to examine the prevalence of current smoking and the factors that influence current smoking among male high school students in Korea according to school type. Methods: Data were extracted from the Korea Youth Risk Behavior Web-Based Survey (2017) and multiple logistic regression was used based on complex sample analysis. The study sample comprised of 15,777 male high school students: 12,583 from general high schools (GHS) and 3,194 from specialized vocational high schools (SVHS). Results: The prevalence of current smoking was significantly higher in SVHS students (19.6%) compared to GHS students (12.6%). Low academic achievement, depressive symptoms, current drinking, and high household economic status were commonly associated with current smoking in male students from both school types. However, exposure to secondhand smoking at home, non-exposure to anti-smoking advertisement, exposure to tobacco advertisement, participation in smoking prevention or cessation education were related to current smoking in GHS students, while living in rural area was associated with current smoking in SVHS students. Conclusion: To reduce current smoking among male high school students, it is necessary to develop smoking prevention policies reflecting the factors associated with current smoking that are different by school type.

Objectives: There is an increasing number of North Korean adolescents in South Korea. These adolescents need clinical attention as they experience a high risk of suicidal behavior because of the childhood adversity and acculturative challenges that they face before and after arriving in South Korea. This study assessed the risk of suicide attempts among North Korean adolescents compared to South Korean adolescents, and investigated the contributing factors for each group. Methods: We used data from the Korean Youth Risk Behavior Web-Based Survey (KYRBS) spanning 2011 to 2018, in which 404 adolescents had a father and/or mother who was a North Korean native. Data on 1,212 propensity-matched South Korean adolescents were extracted from the 2011 to 2018 KYRBS. Prevalence was calculated and compared by group. Separate odds ratios were calculated by group. Results: The North Korean group had a significantly higher suicide attempt rate [unadjusted odds ratio (OR)=8.27; adjusted OR=8.45]. Multivariate analysis indicated that having a low or high socioeconomic status and depressive symptoms were significantly associated with suicide attempts in North Korean adolescents, while being female, having a high socioeconomic status, alcohol use, and depressive symptoms were significantly related to suicide attempts in South Korean adolescents. Conclusion: The results found similarities and differences in the factors associated with the likelihood of suicide attempts in the two groups. From these results, different approaches are needed when planning interventions for each group.

Purpose: The purpose of this study was to compare the mental health factors related to health risk behaviors between multicultural and monocultural adolescents. Methods: The study subjects were selected from the 2018 Korea Youth Risk Behavior Web-Based Survey Dataset. A total of 60,040 multicultural and monocultural adolescents were included in the analysis. A $x^2$ test and logistic regression were conducted, using SPSS 18.0, to compare the general characteristics, mental health, and health risk behaviors of the multicultural and monocultural adolescents. This process involved a complex sample design. Results: There was a significant difference in the rates of suicidal behaviors. Multicultural adolescents showed a significantly higher rate of suicidal ideation (8.6% vs. 8.5%, p=.004), suicidal plan (3.2% vs. 2.4%, p=.004), and suicidal attempt (5.0% vs 3.1%, p=.04) than monocultural adolescents. Perceived stress had a significant impact only on monocultural adolescents. Monocultural adolescents with high levels of perceived stress were at a greater risk of drinking (high stress=reference; low stress OR=0.91, p=.025) and smoking (high stress=reference; low stress OR=0.90, p=.029) than those with low stress. Multicultural adolescents who had made suicide attempts were at a higher risk of drinking (multicultural OR=7.879, p<.001; monocultural OR=2.481, p<.001) and smoking (multicultural OR=4.011, p=.015; monocultural OR=2.800, p<.001) than monocultural adolescents. Conclusion: To implement an effective smoking and drinking prevention program, it is necessary to consider how we can reduce the risk factors. Stress management is important for monocultural adolescents and a proactive suicide-screening program and a suicide prevention program should be included in the program for both multicultural and monocultural adolescents.

Objectives The purpose of this study is to investigate the relationship between physical activity and growth indices. Methods 5963 of 12 years old adolescents were participated in the 10th Korea Youth Risk Behavior Web-Based Survey (KYRBWS-V) project in 2014. These data was analyzed to show the relationship between physical activity and height, BMI. Results According to the Physical Activity guidelines, the mean height was higher in the each male and female group with 'moderate physical activity for at least 60 min ${\geq}7$ days/week', 'vigorous physical activity ${\geq}3$ days/week', and 'muscle-strengthening activity ${\geq}3$ days/week' compare to the group who did not. The mean BMI was lower in the male group of 'sitting for watching TV or computer, etc on a weekday < 3 hr/day' compare to group who did not. Conclusions These results showed that physical activity in adolescence is correlated to growth. Therefore, this research can be one of the reference data to show the proper physical activity is important in the growth.

Objectives: Anxiety disorder is among the most prevalent mental illnesses among adolescents. Early detection and proper treatment are important for preventing sequelae such as suicide and substance use disorder. Studies have suggested that sleep duration is associated with anxiety disorder in adolescents. In the present study, we investigated the association between sleep quality and anxiety in a nationally representative sample of Korean adolescents. Methods: This cross-sectional study was conducted using data from the 2020 Korea Youth Risk Behavior Web-based Survey. The Generalized Anxiety Disorder-7 questionnaire was used to evaluate anxiety. The chi-square test was used to investigate and compare the general characteristics of the study population, and multiple logistic regression analysis was used to analyze the relationship between sleep quality and anxiety. Results: In both sexes, anxiety was highly prevalent in participants with poor sleep quality (adjusted odds ratio [aOR], 1.56; 95% confidence interval [CI], 1.43 to 1.71 in boys; aOR, 1.30; 95% CI, 1.19 to 1.42 in girls). Regardless of sleep duration, participants with poor sleep quality showed a high aOR for anxiety. Conclusions: This study identified a consistent relationship between sleep quality and anxiety in Korean adolescents regardless of sleep duration.
