There is a lack of data on metabolic risk factors during pre-puberty, which is important for identifying the subgroups of youth, at whom early interventions should be targeted. In this study, we evaluated the prevalence of metabolic risk factors and its subsequent relations with dietary patterns in Korean pre-pubertal children through a cross-sectional sample (n = 1,008; boys = 513) of pre-pubertal children (aged 8-9 years) from a sub-study of the Korea Metabolic Syndrome Research Initiatives (KMSRI) in Seoul, Korea. Measures of anthropometry and blood pressure as well as fasting blood samples were used in the analysis. A three-day food records were collected. The metabolic syndrome was defined according to the age-adjusted National Cholesterol Education Program Adult Treatment Panel III guidelines. An added metabolic risk score was calculated for each subject by summing the quintile values of the five individual risk factors. Among the 5 risk components of metabolic syndrome, high waist circumference (WC) was the major factor (P < 0.001). A significant increasing trend of the added metabolic syndrome risk score was observed with the increase of WC (P (trend) < 0.001) among both genders. The cutoff point for high WC for pre-pubertal children was 61.3 cm for boys and 59.9 cm for girls. The prevalence of high triglyceride (TG) values was significantly higher in girls than it was in boys (P < 0.01). Girls in the highest quintile of balanced dietary pattern scores had lower TG values (P (trend) = 0.032) than did those in the lowest quintile. Moreover, girls in the highest quintile of western dietary pattern scores showed increasing trend for the added metabolic risk score (P (trend) = 0.026) compared with those in the lowest quintile. Adverse associations exist between western dietary patterns and the accumulation of metabolic risks among girls, not in boys, even during pre-puberty.

Objectives: This study aimed to determine whether adolescents with allergic rhinitis are at an increased risk of stomatitis and to ascertain possible sex-specific differences. Methods: The data for this cross-sectional study was obtained from the 18th Korea Youth Risk Behavior Web-based Survey (2022). Of the 56,213 students surveyed, 51,850 (boys 26,397 and girls 25,453) were included in the final analyses. Multivariate logistic regression was performed to identify the impact of allergic rhinitis on the risk of stomatitis among Korean adolescents. Results: In Model II, which was adjusted for allergic disease, boys with allergic rhinitis had a 1.53-fold (adjusted odds ratio [aOR]=1.53, 95% confidence interval [CI]=1.40-1.67), and girls had a 1.35-fold (aOR=1.35, CI=1.25-1.46) elevated risk of stomatitis than in those without. In Model III, after adjusting for all covariates, boys with allergic rhinitis had a 1.48-fold (aOR=1.48, CI=1.36-1.62) elevated risk of stomatitis than in those without, and girls had a 1.32-fold (aOR=1.32, CI=1.22-1.43) elevated risk, which remained statistically significant after adjusting for covariates. Therefore, allergic rhinitis in adolescents exerts a detrimental effect on the risk of experiencing stomatitis symptoms; the risk was higher in boys than in girls. Conclusions: These findings suggest that oral health care attention and intervention are needed for adolescents with allergic rhinitis.

Objective: Ligament laxity and hypotonia are characteristics of Down syndrome patients. The aim of this study was to compare the landing pattern between Down syndrome patients and typically developing subjects. To compare the landing pattern, variables related to ligament laxity and hypotonia i.e. vertical stiffness and lower extremities kinematics were investigated. Method: Five subjects with Down syndrome (age: $14.6{\pm}1.8years$, mass: $47.6{\pm}6.94kg$, height: $147.9{\pm}6.0cm$) and six able-bodied subjects (age: $13.2{\pm}0.4years$, mass: $54.7{\pm}6.7kg$, height: $160.1{\pm}9.8cm$) participated in this study. Results: The vertical displacement of the center of mass, vertical reaction force, leg stiffness and range of ankle angle range among Down syndrome patients were significantly different than typically developing group. The youth with Down's syndrome appeared to receive greater vertical impact force at landing than normal youth. Conclusion: The differences in the biomechanical characteristics suggest the delay in motor development among Down syndrome patients and an increased risk of injury to the lower extremity during movement execution such as drop landing.

Purpose: This study aims to investigate the association between suicidal thoughts and the co-occurrence of alcohol, tobacco, and drug use among adolescents. Methods: This study used the data of the Korea Youth Risk Behavior Web-based Survey from 2008 through 2014. The subjects of this study were 517,866 students, in total (Male 266,500, Female 251,366). Frequency analysis was conducted on the data about the subjects' general characteristics and their experience of smoking, drinking, and drug use. The relationship between suicidal thoughts and the co-occurrence of alcohol, tobacco, and drug use was analyzed through ${\chi}^2-test$ and logistic regression. The analyses were done using SAS 9.4. Results: According to the study, adolescents who used alcohol, cigarettes, and drugs at the same time engaged in suicidal ideation 3.69 times more than their peers who didn't use such substances (95% CI: 3.40~4.00, p<.001). Also, adolescents who used only tobacco, only alcohol, and only drugs engaged in suicidal ideation 1.49 times (95% CI: 1.43~1.56, p<.001), 1.28 times (95% CI: 1.26~1.31, p<.001) and 2.34 times (95% CI: 2.04~2.69, p<.001) more than the students who didn't use any substances, respectively. Conclusion: Adolescents' suicidal ideation and the co-occurrence of alcohol, tobacco, and drug use had a statistically significant relationship.

Purpose: The purpose of the study was to investigate health behavior changes in Korean adolescents before and during the COVID-19 pandemic. Methods: A descriptive cross-sectional design was employed. Data were obtained from the 15~16th (2019~2020) Korea Youth Risk Behavior Web-based Survey. Overall, the data of 112,251 students, 57,303 before the COVID pandemic and 54,948 during the pandemic, were included. The data were analyzed using rao-scott 𝝌²-test, t-test, ANCOVA and logistic regression analysis. Results: While sitting time for study decreased, sitting time for leisure increased in the 2020 group compared to the 2019 group. The 2020 group was more likely to skip breakfast and have a higher BMI than the 2019 group. The 2020 group was less likely to consume fruit and engage in moderate and vigorous physical activities than the 2019 group. The 2020 group was less likely to engage in CC, EC, and HTP current smoking and be exposed to secondhand smoke at home, school, and public places than the 2019 group. The 2020 group was more likely to be satisfied with sleep, but less likely to experience stress, depression, suicidal ideation, suicidal plans, and suicidal attempts than the 2019 group. Conclusion: It is necessary to reduce sedentary time, encourage physical activities, manage smoking and drinking rates continuously, and establish a network system to prevent psychological loneliness and isolation for adolescents, which requires participation of experts from the community as a whole.

Purpose: The purposes of this study were(a) to identify smoking behavior by following a cohort representative of the population of 4th grade elementary schoolers in South Korea over a four-year period(2004-2007), and(b) to explore predictors of smoking initiation among non-smokers in Wave 1. Methods: Secondary data, the Korea Youth Panel Study, was analyzed in this study. First, frequencies or percentages were calculated to identify smoking behavior(i.e., smoking initiation, smoking intensity, and smoking duration). Second, binary logistic regression analysis was performed to examine significant factors related to smoking initiation. Results: Smoking initiation and daily smoking were more pronounced when the participants entered middle school. In bivariate analysis, statistically significant predictors of smoking initiation were loneliness at school, self-control, delinquent behavior, depressive symptoms, and stress. However, after controlling for other factors, only a high level of risk-taking tendency and a greater number of delinquent behaviors remained statistically significant. Conclusion: Based on greater involvement in smoking among first-year middle schoolers, smoking prevention strategies should be provided to elementary schoolers rather than middle schoolers. A risk-taking tendency and delinquent behaviors should be considered as proxy measures to detect the high-risk group for smoking initiation.

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.

Objective: This study examined the mediating effect of adolescents' self-esteem on the relationship between their childhood abuse experiences and school rule-breaking behavior. Methods: The research participants consisted of 1,748 adolescents aged from 15 to 16. Adolescents' school rule-breaking behavior and self-esteem were measured in 2016, whereas their childhood abuse experiences were measured in 2010. Panel data collected by the National Youth Policy Institute were analyzed using the bootstrapping technique and PROCESS Macro for SPSS. Results: The results of the study are as follows. First, the adolescents' childhood abuse experiences affected their school rule-breaking behavior. That is, the adolescents who were abused by their parents were at higher risk of breaking school rules later in life. Second, the adolescents' self-esteem mediated the relationship between their childhood abuse experiences and school rule-breaking behavior. The adolescents who were abused by their parents tend to have low levels of self-esteem and thereby break school rules. Conclusion/Implications: The present study shows the possibility that childhood abuse experiences lead to adolescents' problematic behaviors, such as school rule violation. It also indicates that it is necessary to provide counseling and therapeutic interventions for enhancing the self-esteem of adolescents of the at-risk group with childhood abuse experiences.
