Objective: This study assessed the association between subjective body image or objective body mass index (BMI) and the risk of daily smoking in Korean adolescents, with a purpose of identifying the most suitable models. Materials and Methods: Using the 2013 9th Korea Youth Risk Behavior Web-based Survey data for 72,435 students, odds ratios were calculated for daily smoking in the past month, according to the subjective body image and calculated BMI using a respective multiple logistic regression model. The combined effect of these two factors was also analyzed by pairing a BMI category with a subjective body image category, using odds ratios for the same event within each sex group. Results: Among the surveyed students, 7.2% of boys and 1.8% of girls were classified as daily smokers. Students who perceived themselves as being very obese tended to be at lower risk of daily smoking (OR=0.61 in boys with 95% CI=0.47 to 0.79; OR=0.66 in women with 95% CI=0.47 to 0.93). In addition, boys within the obese or overweight BMI category showed a lower risk of daily smoking (OR=0.86, 95% CI: 0.77-0.96). Lean BMI was significantly associated with higher odds ratios for daily smoking only in female students (OR=1.24, 95% CI: 1.02-1.52). When pairing these two objective and subjective factors, results suggested that subjective body image has a greater effect on daily smoking than BMI in both boys and girls. Conclusions: In both male and female students, subjective body image had a greater effect on daily smoking than body mass index. A model using the combination of BMI and subjective body image was the best fit in girls, in contrast to the model using subjective body image only best suitable in boys, for the prediction of daily smoking. These results including several factors associated with daily smoking in Korean students, provide useful data for the development and implementation of smoking intervention and cessation programs for adolescents.

This study demonstrates the association between total sleep duration of adolescents, and its effects on their physical and mental health. Chi-square test and the multiple logistic regression model were applied to analyze the data collected in 2018 by the Korean Youth Health Behavior Survey (n = 52,928), conducted by the Korea Centers for Disease Control & Prevention. Our analysis indicates increased suicidal ideation with insufficient total sleep duration as per the recommended amount and grade (OR: 1.17, 95% CI: 1.06-1.29, p-value: 0.00]. Especially, insufficient sleep among adolescent girls significantly increases the risk of suicidal thoughts (OR: 1.22, 95% CI: 1.06-1.41, p-value: 0.01). Sufficient sleep showed reduced risk of suicidal ideation among boys (OR: 0.83, 95% CI: 0.71-0.96, p-value: 0.02). We propose that to reduce the risk of suicide among teenagers, policy considerations are required to ensure sufficient sleep.

Objectives : This study examined the oral health behavior and dental services utilization of adolescents in order to provide information on how to disseminate the correct oral health behavior to the youth and develop programs for the approach. Methods : The raw data of 'The Third 2007 Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analyzed. All survey data collected was processed using SPSS ver 17.0 for data analysis as Frequency analysis, chi-square and Logistic regression analysis. Results : 1.The adolescents who have parents with college degree are 70% higher of dental services utilization than the adolescents counterpart(whose parents don't have degrees). And also the adolescents living in cities are 1.3 times higher use of dental services than others living in countries. 2. In case of drinking soda, students having soda 4 days per week on average are 1.2 times higher use of dental services than who don't. 3.The students brushing teeth after lunch are 0.9 times lower use of dental service than who don't. And the students who have tooth ache whenever they have a meal are 1.6 times higher use of dental service than the students who don't have tooth ache. The students who had a dental health education are 1.4 times higher utilization of dental service than who don't. The difference of using dental service between the students who have gum disease and halitosis and the students who don't is almost none. 4. The students who drink alcohol and smoke 10 days more or less a month are 0.8 ~ 0.9 times lower use of dental service than who don't. Conclusions : The rate of utilizing dental service is higher at students who live with parents having college degrees and the more have oral health behavior, the less use of dental service for treatment. We concluded that more educational program should be developed and vitalized so that students can have oral health.

The purpose of this study is to investigate the effects of high school students' academic problems such as academic stress and low academic achievement on suicidal ideation and the mediating effects of individual-level risk factors (e.g., depression, aggression) and protective factors (self-esteem, emotion regulation) on the relationship between academic problems and suicidal ideation. This study used data of three waves(2005-2007) from the Korea Youth Panel Survey(KYPS). The analyses were conducted on 2,093 academic high school students, who participated in this panel study. The results from structural equation modeling show that academic stress has positive effects on depression and aggression, but negative effect on self-esteem. Low academic achievement has positive effect on aggression but negative effect on self-esteem. Depression and aggression as individual-level risk factors have positive effects on suicidal ideation. In contrast, self-esteem and emotion regulation as individual-level protective factors have negative effects on suicidal ideation. The relationship between academic problems and suicidal ideation is mediated by depression, aggression, and self-esteem. Based on the study findings, practice implications for youth welfare are discussed to screen high-risk youths and to prevent adolescent suicide in advance.

Little is known about the relationships among adolescents'academic stress, self-efficacy, and internalization externalization. Much less is known about whether there is gender differences in the relationships. This study aims to examine (1) the effects of academic stress on internalization externalization, (2) whether self-efficacy mediates the relationships between academic stress and internalization externalization, and (3) whether there is gender difference in the relationships. For these purposes, we used Structural Equation Modeling and multi group analysis involving 2,844 middle school students participated in the Korean Youth Panel Survey. The results are as follows. First, adolescent's academic stress affected internalization externalization. Second, self-efficacy mediated the relationship between academic stress and internalization externalization. Finally, the multiple group analysis results indicated that the path coefficient between academic stress and internalization of girls was significantly greater than that of boys. Based on these results, we discussed theoretical and practical implications and suggested directions for future research on academic stress coping processes among adolescents.

This thesis analyzed the correlation between the psychological characteristics of adolescents and the use of games in the first year students of the national high school in 2016. The game is one of the representative entertainment industries in Korea and is an industry that has a great influence on becoming a powerhouse as cultural contents. However, games and immersion are expressed as a negative vocabulary of game addiction and are referred to as social problems and youth problems, and they give negative perception to the content of games. All users have the right to enjoy the content, but only negative words are used in poisonous games and they are packed as if they are social problems. In the present study, many emotional problems that were derived from previous studies were not related to game use in general adolescents. Through the questions related to 'depression', students who are not motivated or energy. The results of this study are as follows. First, the positive effects of game and youth emotional problems were derived through the conclusion that students who are active and emotionally bright are more likely to use game contents. This study was conducted to help change the social perception of the game positively by breaking the social fixed point of view that the emotionally troubled adolescents engage with the game and cause social problems.

Various international reports have shown strong proof that socioeconomic and sociodemographic variables are correlated with allergic diseases, yet little is known about how these variables affect Korean adolescents. This study was conducted to identify the socioeconomic and sociodemographic risk factors for allergic diseases of Korean adolescents, and to provide information for preventing and managing such conditions. Data from the 2018 Korean Youth Risk Behavior Survey (KYRBS) of 60,040 adolescents was used for this study. An anonymously administered online survey was conducted to collect information on the dependent variables. The independent variables were asthma, allergic rhinitis and atopic dermatitis. Multivariate logistic regression analysis was performed to analyze the correlations between the dependent variables and the independent variables. Low economic status, living with mother, high education level of parents, high school record, obesity, drinking and smoking were the risk factors for asthma. Low economic status, the place of residence, living with mother, high education level of the parents, gender, high school record, obesity, drinking and smoking were the risk factors for allergic rhinitis. Low economic status, living with mother, high education level of parents, genderhigh school record, obesity and drinking were the risk factors for atopic dermatitis. We found that low socioeconomic status and unhealthy behavior were the risk factor for allergic diseases of Korean adolescents. Balanced economic growth in the community and controlling unhealthy behavior can help reduce the prevalence of allergic diseases.

The purpose of this study was to analyze the dietary habits and health risk behaviors of adolescents who experienced part-time job. For this study raw data from the 13th Youth Health Behavior Online Survey (2017) was examined. Dietary habits and health risk behaviors for 62,823 adolescents were analyzed according to the experience of part-time job. Collected data were analyzed with the SPSS 24.0 program using descriptive statistics and logistic regression analysis, to which the complex sample design was applied. The odds ratio of no fruit intake in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 1.20 (CI: 1.10-1.31). The odds ratio of fastfood intake in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 1.28 (CI: 1.19-1.38). The odds ratio of present smoking in adolescents who experienced part-time job compared to adolescents who have not experienced a part-time job was 3.48 (CI: 3.17-3.84). The odds ratio of present drinking was 3.36 (CI: 3.14-3.96). The odds ratio of high caffeine intake was 1.11 (CI: 1.04-1.19). The odds ratio of high caffeine intake was 2.29 (CI: 2.06-2.55). In developing health education programs for adolescents, it is necessary to include dietary habits and health risk behavior according to part-time experience.
