Online and offline are not separate worlds, especially for adolescents. Many friends in offline settings originally met each other online, but cross-domain influences have rarely been examined. This study aims to examine how much time adolescents spend with peers in online and offline settings, and how time spent with peers influences their online and offline delinquent behaviors during their middle school years. This study used data from the Korean Children & Youth Panel Survey (KCYPS). We focused on students for whom information was available from all three years of middle school. We used a cross-lagged panel model to examine the bi-directional effect of online and offline behaviors over time. Results show that more time spent with peers offline was associated with more offline delinquency, and more time spent with peers online was associated with more online delinquency. Cross-domain influences were also found: more time with peers offline increased online delinquency, and vice versa. However, this adverse cross-domain influence was observed only for male adolescents, not for female adolescents. Implications for intervention programs are discussed for male and female adolescents.

Purpose: The purpose of this study was to identify predictors of suicidal attempts in adolescents over 5 years after school dropout. Methods: The data of the Panel Survey of School Dropouts (of 2013 to 2017) conducted by the National Youth Policy Institute were analyzed. The analysis used the 2013 survey data as the baseline and examined suicidal attempts from 2013 to 2017. A total of 776 adolescents were included in the analysis. Descriptive statistics, 𝝌² test, t-test, and multiple logistic regression were carried out using SAS 9.2. Results: About 11% (87 out of 776) of the adolescents with an experience of dropout attempted suicide between 2013 and 2017. The risk of suicidal attempts was significantly lower in female (AOR: 0.57, 95% CI: 0.87~0.93) than in male adolescents. The higher the self-esteem, the lower the risk of suicidal attempts (AOR: 0.87. 95% CI: 0.78~0.97). The higher the depression level (AOR: 1.10, 95% CI: 1.05~1.16) and the rate of parental abuse (AOR: 1.09, 95% CI: 1.02~1.18), the higher the risk of suicidal attempts. Conclusion: The findings of the study suggest that those who are male, depressed, have low self-esteem or have been abused by their parents are at high risk of suicidal attempts among the adolescents with dropout experiences. Therefore, early intervention is necessary for those at high risk.

Purpose: The purpose of the study was to compare the characteristics between adolescents who have run away from home before and who have contemplated running away from home before, and to find risk factors that predict runaway behavior among them. Methods: The data of 「the survey on adolescents' right to adequate housing and the way to ensure their housing with the focus on social exclusion」 by the National Youth Policy Institute (2020) were analyzed. A total of 494 adolescents were included in the study. Descriptive statistics, x2 test, t-test, and simple and multiple logistic regressions were carried out using SAS 9.2. Results: Gender, depression, anxiety, self-esteem, and school level were significantly different between the two groups. From the multivariate analysis, the adjusted odds ratio for runaway behavior was significantly higher in male students (AOR: 2.14, p<.001), lower in the middle economic class than in the high economic class (AOR: 0.64, p=.051), lower in the 4th quartile group of self-esteem (AOR: 0.52, p=.041), and higher in high school students (AOR: 1.55, p=.050). Conclusion: Considering that male students, students from wealthier families, students with low self-esteem, and high school students are high-risk groups for runaway behavior, among adolescents who have contemplated running away before, interventions targeting these groups are needed.

Purpose: This study was aimed to identify factors related with depression among boys and girls in Korean middle school adolescents. Methods: This study used the data from the 2007 annual survey of youth health behaviors conducted by the Korea Centers for Disease Control and Prevention between the period of 2007/9/1 and 2007/9/22 (with the extension of 2007/10/1 and 2007/11/3). The target number of this study was 21,047 male and 18,424 female students all in the age group of middle school 1st grade and 3rd grade. Results: Depression of middle school adolescents was 33.4% for male students, 43.8% for female students, 38.3% in overall. With regard to the relationship between the demographic characteristics and the health behavior, both male and female students felt more depressed when they had more stress, followed by the cases with stimulant intakes and chronic diseases. For male students, higher level of physical activity was associated with greater level of the depression. For female students, living with only one parent or other person seem to cause more depression. Conclusion: Depression of middle school adolescents requires a special attention from the family, the school and society in general to find out and eliminate the root of these symptoms.

This study examines links between Korean adolescents' uses of games and their school lives. A gender-based analysis was conducted and moderating effects of social relationship variables were tested. The major findings are as follows. First, some gender differences were found in impacts of game use. For example, although a game addiction variable appeared to influence both male and female adolescents negatively on the school-related conscientiousness, only male students displayed a negative impact of game time. It represents a gender difference in the preferred game genres and ways of using them. Second, the analysis showed that variables of social relationship could moderate the negative effects of game use. While the relationship with father appeared to moderate the negative effects of game time in male adolescents, the relationship with mother turned out to relieve the negative impacts of game addiction in female ones. In the case of male adolescents, however, the relationship with the parents did not show any moderating effect on game addiction. This study supports the claim that it is necessary to take a gendered approach in studying gaming.

Purpose: This study aims to discover the relation between the sleep duration and quality of adolescents and their body mass index. Methods: The study used data obtained through the 2009 online survey on adolescents health behaviors, targeting a total of 75,066 middle and high school students (39,612 of male students and 35,454 of female students). We first performed t-test, ANOVA and Scheffe's test and then the potential variables which was possibly related to the body mass index are determined from the tests. Using the potential variable, we performed the multiple regression analysis to finally identify the relation between the duration and quality of sleep. Results: As a result, the 39.8% of male students and the 46.5% of female students most frequently respond that the sleep duration was less than 6 hours, and 36.4% of male students and the 45.3% of female students respond that the quality of sleep was not good enough. The body mass index of both the male and the female students portionally decreases to their sleep duration, but the better quality of sleep makes their body mass index higher. Conclusion: In conclusion, the body mass index has some notable relationship with the sleep duration and quality for adolescents. It is advised to consider the sleep duration and quality in the business plans for adolescents in order for the prevention of their body mass index.

Background: Tobacco use among adolescents is a major public health concern, and identifying predictors of smoking is necessary for planning prevention programs. The present study examined the relationship between refusal self efficacy, self esteem, smoking refusal skills and water pipe (hookah) smoking among Iranian male adolescents. Materials and Methods: A cross-sectional study was conducted with 380 Iranian male adolescents aged between 15-19 years selected by multistage sampling. The participants completed an anonymous, voluntary, self-report questionnaire. Variables independently associated with water pipe (WP) smoking were identified by multiple logistic regression analysis. Results: The mean age of the participants was $16.7{\pm}1.3$ years. The prevalence of WP smoking was 17.3%. Logistic regression analysis revealed that knowledge (OR=0.56; 95% CI: (0.37-0.79), attitude (OR=0.69; 95% CI: (0.52-0.89), self esteem (OR=0.67; 95% CI: (0.55-0.82), smoking refusal skills (OR=0.73; 95% CI: (0.55-0.87), and self efficacy (OR=.82; 95% CI: (0.61-0.93) were all signifcant prediting facotrs for adolescents WP smoking. Conclusions: The findings have implications for public health interventions. Indeed, self efficacy and smoking refusal skills should be considered when developing tailored measures for the prevention of WP smoking among adolescents.

This study examined the direct and indirect influences of parental behavioral control on adolescents' school related adjustment by exploring pathways between parental behavioral control, adolescents' anxiety, and school related adjustment. Participants were composed of 319 high school 1st graders (153 male and 165 female students) from the Seoul area. They completed questionnaires on parental behavioral control, adolescents' anxiety, and adolescents' school related adjustment. The collected data were analyzed using Pearson's correlation coefficients, Factor Analysis, and Structural Equation Modeling. It was adapted to SPSS version 19.0 and Amos version 21.0 for Windows. The results indicated that adolescents' anxiety partially mediated the association of parental behavioral control and adolescents' school related adjustment. More concretely, direct effect of adolescents' anxiety on adolescents' school related adjustment were slightly greater than the direct/indirect effects of parental behavioral control on adolescents' school related adjustment. The effect of adolescents' anxiety on adolescents' school related adjustment was the greatest among all associations between research variables. The findings of this study have implications for research and practice that highlights the important considerations for proper parental behavioral control and reducing adolescents' anxiety that should be emphasized to improve adolescents' school related adjustment. We believe that improved parental behavioral control needs to be emphasized when designing prevention and parent intervention education programs for adolescents' psychological problem and school related adjustment.

The proposes of this study were to exam the effects of internalization of sociocultural values toward appearance on adolescents' body image and clothing behaviors, and to analyze these effects by adolescents' sex and age variables. The research method was survey and the subjects were 447 male and female adolescents in Daejeon, Korea. The questionnaire consisted of 4 measuring instruments; internalization of sociocultural values toward appearance, body image, clothing behaviors, and demographic attributions. The data were analyzed by factor analysis, t-test, variance analysis, Duncan's multiple range test, using SPSS program. The results are as follows. First, most of adolescents showed positive attitude on sociocultural values toward appearance, and female and high school students revealed higher level of internalization than male and middle school students. Second, as a result of factor analysis, 3 factors emerged in body image(appearance interest, appearance evaluation, and weight concern) and 4 factors emerged in clothing behaviors(clothing interest & psychological dependency, clothing ostentation, clothing conformity, and clothing comfort). Third, internalization of sociocultural values toward appearance had important effects on adolescents' body image and clothing behaviors; the adolescents who had high level internalization showed more interest on their appearance and weight and higher clothing interest & psychological dependency and clothing ostentation and lower clothing comfort than other adolescents who had middle or low level internalization. Forth, internalization of sociocultural values toward appearance showed many different effects on body image and clothing behaviors by adolescents' sex and age variables.

Purpose: The purpose of this study was to investigate the relationship between relative handgrip strength (HGS/BMI) and obesity (BMI above 95th percentile) in adolescents. Methods: The subjects of the study were 637 out of 701 adolescents aged 10~18 who participated in the 2018 National Health and Nutrition Survey (KNHANES), excluding those with missing values in body mass index (BMI) and handgrip strength (HGS). The relative handgrip strength (HGS/BMI) value was divided by quartile and composite sample logistic regression analysis was performed to see its relationship with obesity (BMI above 95th percentile). The collected data were analyzed using SPSS 18.0. Results: As a result of analyzing HGS according to gender-specific quartiles, age, height, and weight of male adolescents increased significantly as HGS/BMI increased (p trend<.001). In addition, as HGS/BMI increased, total cholesterol, triglycerides, and HDL cholesterol decreased significantly (p trend<.001). In the case of female adolescents, age and height increased significantly as HGS/BMI increased (p trend<.001). HGS/BMI was lower in the obese group (p=.023), while total cholesterol was higher in the obese group(BMI above 95th percentile) than in the non-obese group. As a result of the composite sample logistic regression analysis, the odds ratio (OR) decreased significantly as the quartile increased in both male and female adolescents. Conclusion: According to these results, a follow-up study is needed to confirm the factors affecting muscle strength of adolescents. In addition, this study intends to be used as basic data to conduct further research and to develop programs that can improve muscle strength and reduce obesity in adolescents.
