The purpose of this study was to identify the impact of pornography use among adolescents on their subsequent violent sexual behavior, and to ascertain the moderating effect of family support. The study was conducted with a sample of 2,087 Korean middle and high-school students. To analyze the data, a descriptive analysis, a correlation analysis, and a Poisson regression were conducted using SPSS 24.0. A Poisson regression was performed because the dependent variable, violent sexual behavior, was measured by the frequency of occurrence, and most responses were distributed at '0', indicating a non-normal distribution. The results indicated that 8.1% of adolescents admitted to having sexually violent experiences over the past year, with a relatively high rate of sexual harassment. Secondly, 53.3% of adolescents had used pornography over the past couple of years, with the highest percentage of use occurring via the Internet. Finally, pornography use among adolescents had a significant and direct impact on their sexually violent behavior, with family support playing a moderating role. This indicated that, for adolescents with a high level of family support, the impact of pornography usage on sexually violent behavior decreased. Based on these results, we discuss practical and policy interventions to prevent sexually violent behavior by adolescents.

Purpose: The purpose of this study was to investigate the influences of sarcopenic and non-sarcopenic obesity on the components of Metabolic Syndrome (MetS) in adolescents. Methods: This study used the fifth Korean National Health and Nutrition Examination Survey data from 2010 to 2011. The study included 859 adolescents aged 12 to 18 years. Descriptive statistics and simple and multiple logistic regression analyses were conducted using SAS 9.2. Results: Based on the results, adolescents with sarcopenic obesity had a higher risk of central obesity (AOR: 23.41, 95% CI: 12.76-43.97), high triglyceride (OR: 4.58, 95% CI: 2.69-7.79), low HDL-cholesterol (AOR: 2.66, 95% CI: 1.74-4.05), high blood pressure (AOR: 3.44, 95% CI: 1.37-8.68), and high fasting glucose (AOR: 2.37, 95% CI: 1.13-4.96) than their normal counterparts. Adolescents with non-sarcopenic obesity had a higher risk of central obesity (AOR: 19.75, 95% CI: 9.73-44.67), high triglyceride (OR: 3.09, 95% CI: 1.22-7.81), and low HDL-cholesterol (AOR: 2.73, 95% CI: 1.37-5.45) than normal youths, and these were not significantly related to high blood pressure and fasting glucose. Conclusion: Sarcopenic obesity was more related to the components of MetS than non-sarcopenic obesity. Since adolescents with sarcopenic obesity are a more vulnerable population, a prevention and management program for MetS and cardiovascular risk should be implemented in this population.

Purpose: Liver metabolism plays a pivotal role in the development of metabolic disorders. We aimed to investigate the clinical and laboratory risk factors associated with alanine aminotransferase (ALT) levels in young adolescents from an urban population in Korea. Methods: A population of 120 apparently healthy adolescents aged 12-13 years was included in the cross-sectional design study; 58 were overweight or obese and 62 were of normal weight. We estimated anthropometric and laboratory measurements, including waist-to-height ratio, blood pressure, insulin sensitivity, aspartate aminotransferases (AST), ALT, and lipid profiles. Results: The mean ages of the overweight or obese and normal weight participants were $12.9{\pm}0.3$ and $13.0{\pm}0.3years$, respectively. Height, weight, body mass index, waist circumference, waist-to-height ratio, systolic and diastolic blood pressure, AST, ALT, total cholesterol, low-density lipoprotein-cholesterol, triglyceride, insulin, and the homeostatic model assessment of insulin resistance (HOMA-IR) score were significantly higher and the high-density lipoprotein-cholesterol and quantitative insulin-sensitivity check index were significantly lower in the overweight/obese participants in comparison to the normal-weight participants (all P<0.05). In multivariate linear regression analysis, waist-to-height ratio, systolic blood pressure, and HOMA-IR score were independently and positively associated with serum ALT levels. Conclusion: Screening for ALT levels in adolescents may help to differentiate those at risk of metabolic abnormalities and thus prevent disease progression at an early age.

The purpose of the study is to examine the effect of personality style and emotional dysregulation on female adolescents' eating attitude, and the mediating effect of emotional dysregulation on the relationship between personality style and eating attitude. For this research, questionnaires on personality style, emotional dysregulation and eating attitude were administered to 1370 female high school students based in Seoul. Among 1370 questionnaires collected, 1239 were selected and statistically analyzed by frequency analysis, Pearson's correlation analysis, multiple regression analysis, and stepwise multiple regression analysis using SPSS Win 21.0. The main findings of the study are as follows: First, according to female adolescents' BMI, the level of their eating attitude differed significantly. Second, according to female adolescents' BMI, female adolescents' personality style and emotional dysregulation were found to affect their eating attitude significantly. Third, emotional dysregulation had a mediating effect on the relationship between female adolescents' personality style and eating attitude. To be more specific, for the normal weight group of female adolescents, emotional dysregulation was found to have a partial mediating effect on the relationship between sociotropy and eating attitude, and a full mediating effect on the relationship between autonomy and eating attitude. On the contrary, for the overweight and obese groups of female adolescents, emotional dysregulation was found to have a full mediating effect on the relationship between sociotropy and eating attitude, and a partial mediating effect on the relationship between autonomy and eating attitude. The results of the study show the ways in which personality and emotional traits contribute to female adolescents' eating attitude according to their BMI, and provide useful information for treatment of adolescents' eating disorder in clinical settings.

Objective: The aim of the study was to compare the opening and protrusive mandibular movements between Class I and Class II malocclusions in healthy adolescents by clinical and axiographic evaluations. Methods: Mechanical axiography was performed on non-orthodontically treated, temporomandibular disorder (TMD)-free adolescents (12 - 16 years) with Class I (n = 38, 16 boys, 22 girls) or Class II (n = 40, 19 boys, 21 girls) malocclusion. Opening and protrusive movements were measured clinically and axiographically. Intergroup comparisons were evaluated by t-tests. Results: In opening movement, the maximum clinical opening capacity was significantly different (p ${\leq}$ 0.05) between the groups. In protrusive movement, the Class II group had significantly greater maximum clinical protrusion (p < 0.001) and maximum axiographic protrusive length (p < 0.01) than the Class I group. No significant difference in the other opening and protrusive axiographic measurements was observed. Conclusions: TMD-free adolescents with Class II malocclusion have increased protrusive capacity compared with TMD-free adolescents with Class I malocclusion; however, the detected differences could be normal variations during adolescence.

Purpose: This research was performed to investigate Korean adolescents' body weight perception, appropriate weight change efforts, and factors that influencing these efforts. Methods: The data were obtained from 68,136 adolescents, aged 12~18 years from the 2007 Third Korean Youth' Risk Behavior Web-based Survey. Descriptive statistical analysis and odds ratio were calculated by logistic regression. Results: The distribution of the body mass index differed in boys and girls. The accuracy of body weight perception was shown in the order of the underweight (91.6%), overweigh t (73.3%), normal weight (55.4%), obesity (41.3%) groups. Adolescents with high perceived economic status tended to have a high prevalence of accuracy of body weight perception. The distribution of appropriate weight change efforts according to the actual body mass index showed that girls were trying to lose weight more than boys. The results of a logistic regression analysis regarding appropriate weight change efforts showed differences according to gender, perceived economic status, mother's educational level, and family affluence scale. Conclusion: Appropriate body weight perception and change management plans are needed for Korean adolescents. In addition, active weight change programs have to be established in the adolescents' living environments, such as schools.

Purpose: The purpose of this study was to investigate the affect of eating behaviors on subjective health of multi-cultural adolescents in South Korea. Methods: This study is designed as cross-sectional. Using the statistics from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. Overall, 711 multi-cultural adolescents were included in the analysis. Results: When analyzing the factors affecting the subjective health status of multi-cultural adolescents, normal body mass index (OR: 0.56, 95% CI: 0.35~0.89) and milk consumption (OR: 0.54, 95% CI: 0.35~0.83) showed a lower risk of being unhealthy, while skipping breakfast for 5 days (OR: 1.97, 95% CI: 1.33~2.93) and convenience store food consumption (OR: 1.59, 95% CI: 1.05~2.40) showed a higher risk of being unhealthy. Conclusion: It is necessary to form positive eating habits that influence the subjective health perception of multi-cultural adolescents. Therefore, appropriate dietary education and systematic support should be provided for multi-cultural families.

The prevalence of obesity in children and adolescents is increasing worldwide. Obesity in children and adolescents not only increases the risk of transitioning to obesity in adulthood but also increases the risk of cardiometabolic diseases such as high blood glucose, high blood pressure, dyslipidemia, fatty liver, and hyperinsulinemia during childhood. The goal of treating obesity in children and adolescents is not to focus on weight loss but to help children reach a healthy weight while maintaining normal growth appropriate for their age and sex. To achieve this goal, regular physical activity and exercise, dietary modification, improvement of obesity-prone environmental factors, and behavioral changes are required for a healthy lifestyle. If appropriate weight control is not achieved through lifestyle modifications, pharmacotherapy may be considered for adolescents with severe obesity aged 12 and above. Recent clinical trials have reported the efficacy and safety of pharmacotherapy in severely obese adolescents. Currently, two medications can be prescribed in Korea for patients with obesity aged 12 and above: Orlistat and Liraglutide. However, despite effective weight control through drug treatment, body weight may increase again after treatment discontinuation. Therefore, it is crucial to evaluate adherence to health behaviors during visits and continue to educate on lifestyle modifications, even during pharmacotherapy, to minimize weight regain.

Purpose: The purpose of this study was to identify attitudes of adolescents toward suicide. Methods: Q-methodology which provides a method of analyzing the subjectivity of each item was used. Thirty middle and high school students classified 37 selected statements into a normal distribution using a 9 point scale. Collected data were analyzed using the Quanl PC Program. Results: Three types of attitudes toward suicide were identified. The first type (opposing suicide-moral minded) showed an attitude of opposing suicide and thinking that suicide is a sin. The second type (understanding-empathizing suicidal person) showed an attitude of understanding the situation of the adolescents who has suicidal ideation and empathizing with them. The third type (ambivalent attitude) showed an attitude of understanding the suicidal person but, at the same time, opposing suicide. Conclusion: Results of the study indicate that different approaches to suicide prevention programs should be developed based on the three types of suicide attitudes among adolescents.
