Purpose: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. Methods: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). Results: At the school level, the average school body mass index (BMI, $kg/m^2$) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI ($kg/m^2$), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. Conclusion: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

Purpose : This study examined the factors related to sexual intercourse among adolescents in South Korea. Methods : The study sample was comprised of 65,528 middle and high school students aged 12 to 18 years in 2016. For this study, using the data from the 12th Korea youth risk behavior web-based survey, a chi-squared test, and hierarchical logistic regression analysis we reconducted with the SPSS 22.0 program considering personal, family, school, and regional characteristics. Results : The proportion of adolescents who had sexual intercourse was 6.0 % of boys and 2.7 % of girls, and 6.3 % of high school students and 2.4 % of middle school students. The statistically significant related factors of sexual intercourse were gender, grade, attempted suicide, ever drinking, ever smoking, habitual or purposeful drug use, weekly allowance, and coed school in the final model 4. Adolescents with suicide attempts had 2.49 times more sexual intercourse than adolescents with no experience of suicide attempts. Compared to adolescents without alcohol, smoking, and habitual drug use, those who have experienced alcohol, smoking, habitual or purposeful drug use were 2.22 times, 3.76 times, and 3.39 times more likely to have had sexual intercourse, respectively. Adolescents with a weekly allowance of more than 100,000 won per week and adolescents in coed schools were 2.84 times and 1.40 times more likely to have had sexual intercourse, respectively. Conclusion : Multi-level interventions should be considered in school sexual education programs while considering the substantiality of sex education and the actual adolescents' needs. In addition, sexual health interventions in cyberspace for high-risk groups may be needed to consider the emotional and mental characteristics, given the factors related to sexual intercourse in adolescents.

Objectives: The rapidly changing dietary environment requires a study that addresses the status of middle and high school students regarding their consumption of convenience food sold at convenience stores. Methods: This study examined adolescents' lifestyle patterns, dietary habits, and status of consuming convenience food at convenience stores. A total of 659 students (329 middle school students and 330 high school students) in Incheon participated in this questionnaire survey. Results: The mean age of the subjects was 13.7 years for the middle school students, and 16.6 years for the high school students. The gender and grade distributions in the middle and high school students were similar. The middle school students reported that they spent more time using electronic devices (p<0.001) or watching TV (p<0.001) than high school students. More than 60% of middle and high school students consumed convenience food at convenience stores without statistical difference between the two groups. The main reason for consuming convenience food from convenience stores was its convenience followed by taste in both groups. Despite the high frequency of consuming convenience food, the students rarely checked the nutrition labels at the time of purchase. On the other hand, they were still most concerned about the nutritional value of the convenience foods when they consumed convenience foods. The most frequently consumed convenience food was ramyon in both groups. Significant positive correlations were observed between the frequency of consuming convenience food at convenience stores and lifestyle factors for the middle school students, including monthly allowance, time for using electronic devices, and number of private lessons. For the high school students, however, the only monthly allowance had a significant positive correlation with the consumption. Conclusions: Adolescents are increasingly exposed to convenience foods and relevant nutritional issues are a concern. Therefore, a dietary environment that is adequately formed for the healthy development of youth as well as systematic nutrient education that is appropriately designed for both middle and high school students is required.

Objectives: This study assessed the influences of various factors that are related to youth smoking such as gender, age and type of school, and we wanted to provide supporting data for tailored and effective policy initiatives to reduce adolescent smoking. Methods: A self-report survey was conducted on 14,910 teen-age students who were selected based on the nationwide distribution of students in large and small cities and counties, the gender ratio of the students and the ratio of students attending various type of school at 38 middle and high schools in six representative areas of each province. The survey was handled and managed by a health education teacher at each school. Binary and multinomial logistic regression was used in the analyses. Results: Smoking by adolescents was associated with gender, age and even height. Male high school students tended to smoke more than female high school students, but this differences was not significant for middle school students. The older the adolescents were, the more likely that they smoked, except for the female high school students. Height was meaningful for all adolescents, except for the boys at the vocational high schools. Monthly allowance was significant for all adolescents. School factors such as type of school and the students' school performance were also crucial factors. Attending a vocational high school was strongly related to smoking, especially for girls. Students' school performance and the perceived level of stress were strongly associated with smoking, especially for boys. Home factors such as the relationship with parents and conversation time with family members were closely related to smoking behavior. Knowledge about the health hazard of smoking was also found to be strongly related to adolescent smoking. Conclusions: In conclusion, demographic factors, school factors, home surroundings and the perception on the harmfulness of smoking are strongly related to adolescent smoking behavior, but these differ from gender and type of school.

This study was the first attempt to investigate which factors influence problem gambling among out-of-school adolescents in South Korea. Using data from the 2015 Survey on Youth Gambling Problems, this study examined the influences of personal characteristics and betting games on problem gambling among out-of-school adolescents. Regression analyses of personal characteristics on problem gambling showed that being male adolescents, having more allowance, living without parents/guardians, or belonging to probation was associated with higher likelihood of doing problem gambling among out-of-school adolescents. Also, regression analyses of betting games on problem gambling revealed that doing betting games more frequently, doing betting games more time, or spending more money on betting games was associated with higher likelihood of doing problem gambling among out-of-school adolescents. Based on the findings, this study suggested practice and policy implications for addressing problem gambling among out-of-school adolescents.

Total 476 adolescents residing in Daegu area participated in this study, and followings are the summary of the results. In terms of concerns in food purchasing, adolescents put priority in order of price(3.81±0.64), taste(3.70±0.72), safety(3.52±0.78), health(2.93±0.92). With respect to food purchasing attitudes, a significant differences were found in economic concern(p<.05) by gender and by the amount of allowance; preference(p<.01) and safety(p<.01) by school year. The analysis of environmental factors affecting food purchasing attitudes revealed that adolescents were most influenced by their parents(3.44±0.62) in food purchasing, whereas friends' influences(2.43±0.60) were relatively low. Regarding the effect of environmental factors on food purchasing, significant differences were found in parents(p<.05) and brands(p<.05) by gender; friends(p<.01) and parents(p<.05) by school year; friends(p<.01) by the amount of allowance. Food purchasing attitudes represented positive correlation with parents, advertisements and brands(p<.001). In addition, regression analysis showed that parents and advertisements affect adolescents' food purchasing. Conclusively, adolescents appear to prioritize price and taste, and they were influenced most by their parents when purchasing food. Therefore, parents, serving as a consumer role model, should instruct their children to learn considerate attitude in food purchasing.
