This study was conducted to explore socio-demographic influences on eating behaviors among adolescents in Korea. Data were obtained from the Eleventh Korea Youth Risk Behavior Web-based Survey (2015 KYRBS), a nationwide representative sample of 3,532,149 middle and high school students. The data were analyzed by descriptive analysis, t-test, and logistic regression based on complex sample design using SPSS 20.0 statistics. The results showed that intake frequency of soda, fast food, and instant noodles was higher in male than female students (P<0.001). Additionally, the frequency of eating breakfast, fruits, vegetables, and milk was higher among high school students than middle school students (P<0.001). Higher levels of economic status were associated with less skipping breakfast. Adolescents with mothers that had higher levels of education were more likely to be frequent consumers of fruits, vegetables, and milk, and to eat breakfast.

Purpose: The purpose of this study was to compare the factors related to violence victimization between multicultural and Korean-origin adolescents. Methods: This study used the data of the 2017 Korea Youth Risk Behavior Web-Based Survey. A total of 54,748 multicultral and Korean-origin adolescents were included in the analysis. Weighted percentage and means were used to describe the sample. Simple and multiple logistic regressions were conducted using SAS 9.2. Results: The multicultural adolescents experienced more violence victimization than Korean-origin adolescents. In both groups, middle school students, habitual drug users, and those not living with their family showed a greater risk of becoming a victim of violence. In Korean-origin adolescents, while girls and those with mid-level family economic status showed a lower risk, those who had experienced sadness or despair, suicidal ideation, smoking and problematic drinking showed a higher risk of becoming a violence victim. In multicultural adolescents, those with a lower subjective health status and a lower stress level had a higher risk of violence victimization. Conclusion: Results of this study suggest that the factors significantly related to violence victimization differ between multicultural and Korean-origin adolescents. Therefore, different approaches are required for the prevention and management of violence victimization in different populations.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16,574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

This study was conducted to investigate the eating habits, self-perception of body image, and weight control behavior in Korean adolescents by gender. Data pertaining to 70,809 subjects(male 37,090, female 33,719) were obtained from the sixth Korea Youth Risk Behavior Web-based Survey(2010). The rate of skipping breakfast was 42.5% in male, and 45.8% in female students. The intake frequency of vegetable, milk, soda, fast food, and instant noddles was higher in male than female students. Moreover, 33% of male and 31.9% of female students considered themselves to be somewhat or very obese. Notably, 2.3% of underweight students considered themselves to be obese. Weight control measures were practiced in 44.6% of male, and 54.6% of female students. Meal restrictions were used more frequently to control weight by females, while exercise was used more by males. The perceived stress level was higher in female than male students, especially that due to appearance. Therefore, integrated and personalized high school nutrition programs according to gender should be implemented to establish proper body image perception and eating habits, as well as to develop selfesteem.

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: 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.

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: This study aimed to compare dietary patterns (missed meals, eating instant foods, skipping fruits/vegetables) between general and multicultural adolescents in Korea. Methods: Data from the 9th Korea Youth Risk Behavior Web-based Survey (2013) were used, and analysis was done for the 66,951 youth using SPSS 18.0. Results: The rate of lunch absence accounted for 7.3% in general adolescents and 8.3% in multicultural family adolescents. However, the response of breakfast absence for a week was higher than the rate of the absence of lunch and dinner. For eating instant foods at least more than once a week, there was a significant difference for carbonated drinks, snacks, ramen and fast food in multicultural adolescents. More multicultural adolescents also noted "never ate fruits and vegetable within the recent week." Conclusion: For the healthy diet of adolescents, more careful observation and nursing education should be implemented. Furthermore, parents should also be included in the education altogether.

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.
