Objectives: The purpose of this study was to investigate the relationship between oral health factors and suicidal ideation in adolescents in order to provide basic data for adolescent suicide prevention and oral health promotion. Methods: This study used data from the Korea Youth Risk Behavior Web-Based Survey held in 2017, in which a total of 62,276 youth participated. Data were analyzed by SPSS Ver. 22.0. Complex logistic regression analysis was used to analyze oral health factors related to suicidal ideation. Results: The effects of oral health on male students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.01), while suicidal ideation was increased in individuals who had experienced scaling within the past year (p<0.001), or, among experiences of oral disease within the last year, had reported prickling and throbbing pain (p<0.001), pain on the tongue and inside the cheeks (p<0.001), or bad breath (p<0.001). The effects of oral health on female students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.001), while suicidal ideation was increased in individuals who, among experiences of oral disease within the last year, had reported pain when chewing (p<0.001), pain on the tongue and inside the cheeks (p<0.01), or bad breath (p<0.001). Conclusions: The above results demonstrate that adolescent suicidal ideation and oral health factors are correlated, and it will be necessary to incorporate oral health interventions when planning or developing projects and programs for suicide prevention in adolescents.

This study aimed to investigate the relationship between the general characteristics of adolescents and their mental health in relation to experiences of heavy drinking. The research utilized raw data from the 18th Youth Health Behavior Online Survey (2022), focusing on 530 participants who reported experiencing heavy drinking in the past 30 days. The study applied weighted composite sample analysis, incorporating frequency, chi-square test, and logistic regression to examine the data. According to the research findings, experiences of heavy drinking showed statistically significant differences across variables such as gender, academic achievement, economic status, sexual experience, and smoking. Additionally, among the mental health characteristics, stress perception, depression, loneliness, suicidal thoughts, suicide planning, and suicide attempts were identified as influencing factors on heavy drinking experiences. These results underscore the need for prevention programs addressing alcohol consumption habits, considering the mental and physical health of adolescents. Developing programs that take into account the relationship between mental health and drinking habits can contribute to forming healthy lifestyle habits during adolescence.

Objectives：This study was aimed at examining the emotional predictors of adolescent suicidal ideas in a community. Methods：The subjects were 1909 middle and high school students(936 males, 973 females) in Koyang-shi. We evaluated all subjects using Center for Epidemiologic Study for Depression(CES-D), Revised Children's Manifest Anxiety Scale(RCMAS), Korean-Youth Self Report(K-YSR), Psychological Self-1 of Offer's Self Image Questionnaire(PS-1 of OSIQ) and Suicide Ideation Questionnaire (SIQ). We compared the PS-1 of OSIQ scores of Anxious-depressive group(above cut-off points of CES-D, RCMAS and K-YSR) to those of control group, and conducted correlation analysis and stepwise multiple regression analysis to all subjects. Results：The number of anxious-depressive group was 126(6.58%) among 1909 subjects with significant gender difference(M：F ratio 1：1.5). Both PS-1 of OSIQ and SIQ scores were significantly higher in Anxious-depressive group than in control group. There were significant correlations among the scales：CES-D, RCMAS, A/D of K-YSR, PS-1 of OSIQ and SIQ. Through stepwise multiple regression analysis, we found that significant predictors of suicidal idea were CES-D, RCMAS and A/D of K-YSR. Conclusion：Anxious-depressive adolescents may be the high-risk group for suicidality and need preventive interventions of suicidality in a community.

Purpose. The purposes of this study were 1) to examine the differences in suicidal ideation and psychological variables by gender, 2) compare the contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation, and 3) identify the most important predictors of suicidal ideation for male adolescents and female adolescents. Methods. The subjects consisted of 271 male adolescents and 230 female adolescents. Data were collected through self-report questionnaires, which were constructed to include SSI-C, DEP subscale of the SCL-90-R, PACI, and SWLS. The data were analyzed by the SPSS/WIN program. Results. Suicidal ideation differed by gender. Depression and family communication differed by gender. The unique contribution of demographic-behavioral variables and psychosocial variables in explaining the variance in suicidal ideation differed between male adolescents and female adolescents. The significant predictors of suicidal ideation for male adolescents were life satisfaction, depression, and family communication, explaining $28\%$ of the variance in suicidal ideation. The significant predictors of suicidal ideation for female adolescents were depression, smoking, and life satisfaction, explaining $38\%$ of the variance in suicidal ideation. Conclusion. The findings of this study suggest that the approach to effective suicide prevention program for adolescents should consider gender differences.

Objectives: This study investigated the relationship between adolescents' suicidal ideation and their physical health conditions to contribute to lower suicide rates among adolescents. Methods: Secondary analysis of 2108 high school students of $10^{th}$ grade was conducted using the Korean Child and Youth Panel survey in 2013. The association between suicidal ideation and socio-demographic and health characteristics were analyzed using Chi-square tests and regression models. Results: Adolescents' physical health conditions were significantly related to suicidal ideation. In particular, rhinitis and various symptoms such as feeling feverish, low appetite, feeling of nausea, stomachache while studying, and sleeping problem showed statistically significant relationships with suicidal ideation (P < .05). Furthermore, the higher frequency of diseases and body symptoms increases the rate of suicidal ideation. Considering socio-economic characteristics, family structure was also important. Conclusions: Physical health condition is a major contributor to adolescent's suicidal ideation. results suggest that improving social support system for adolescents' physical health conditions across family and school may be important in suicide prevention efforts.

Purpose: This cross-sectional study was conducted to investigate the prevalence of health risk behaviors by gender and grade and to examine the correlation between health risk behaviors and self-efficacy in early adolescents. Method: The sample of this study consisted of 1.693 early adolescents recruited from 7 middle schools in S-Gu, Seoul, Korea. Health risk behaviors were measured by the Youth Risk Behavior Surveillance Survey (YRBS). Self-Efficacy was assessed by General Self-Efficacy (GSE). Results: About a third of the subjects had experience in drinking behavior about 19.4% in cigarette smoking (including cases of just one or two puffs), 25.9% in physical fight, 29.1% in thought about killing themselves (suicide-related behavior), 1.5% in drug. More than a half (60.5%) experienced at least one health risk behavior. Female students were more likely to report drinking experience and suicide-related experience. Health risk behaviors were not significantly correlated with self-efficacy in early adolescents. Conclusions: Many early adolescents had experience in health risk behaviors in the past. The findings of this research suggest the necessity of intensive prevention programs in middle school to motivate and prepare students to avoid these behaviors. In addition, these results may help health professionals plan appropriate screening and counselling for health problems in early adolescents.

Purpose: The purpose of this study was to investigate the effect of physical activity on suicidal ideation according to gender in South Korean adolescents. Methods: This study is designed as a cross-sectional study. Using the statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. The study sample comprised 62,558 middle and high school students aged primarily 12 to 17. Results: The rate of engaging in physical activity more than three times a week was 39.6% for boys and 28.8% for girls and the rate of suicide ideation was 9.35% for boys and 14.9% for girls. Male students were 1.42 times more likely to commit suicide when they did not engage in physical activity than when they do more than three times a week but it was found to have no significant effect on female students. Conclusion: Physical activity should be encouraged in the physical education curriculum and the school health area to reduce suicidal ideation in adolescents. Differentiated interventions are required according to gender. It is suggested that intervention programs involving physical activity be implemented more actively for male students and intervention programs centering on obesity and smoking prevention be implemented for female students.

Purpose: This study was conducted to develop and test a measurement of the suicidal protection(MSP) for high school students in Korea. Methods: Thirty-four preliminary items were initially developed based on literature review and focus group interviews. Those items were evaluated by experts for content validity with 31 items yielded. For testing validity and reliability of the measurement, data were collected from 330 high school students in Korea. Results: The item analysis selected 26 items. One item was deleted additionally through the primary exploratory factor analysis. The final exploratory factor analysis yielded 26 items in six factors such as fear of suicide, self-esteem, emotion regulation, support from others, support from family, and school life, explaining 66.6% of the total variance of the suicidal protection for high school students in Korea. Convergent validity and discriminant validity were supported by construct reliability, average variance extracted estimate, and standardized regression weight. MSP scores were positively associated with economic status, academic record and suicidal ideation. Also, criterion validity was supported through a significant correlation with the Reason for Living Inventory for Adolescent. The Cronbach's ${\alpha}$ reliability coefficient was .93 for the overall measurement and .72~.86 for the six factors. Conclusion: The results show that MSP may be valid and reliable for assessing suicidal protection of high school students.

Borderline personality disorder in adolescents present with suicide attempts or gestures, and they are characterized by the same patterns of splitting, devaluation, manipulation, need-gratifying object relations, impulsivity, and ego deficits that are finds in borderline adults, Symptomatolgy are depression, anxiety, identity crisis, and occasionally antisocial behavior in borderline personality disorder in adolescents. These findings should be differentiated to normal stormy adolescents. Theses borderline personality disorder in adolescents are known about the instability of object relations, labile affect, splitting, and psychotic episode in severe stress. According to thses finding, schizophrenia, mood disorder, schizoptypal personality disorder, paranoid personality disorder could be differentiated. Etiology is complex including psychodynamic, genetic, familial factor. Treatments are individual psychotherapy, group therapy, and pharmacotherapy. The continuity or discontinuity of borderline states from childhoon to adult life is controversy.

Objectives: This study was performed to consider the association between Internet using time for non-educational purposes and adolescent health, and to examine how health status differs between Internet users and non-users. Methods: We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A total of 75 066 adolescents were categorized into four groups according to their Internet using time excluding using for educational purposes: non-Internet users (NIUs), occasional Internet users (OIUs) (<1 h/d), moderate Internet users (MIUs) (${\geq}1$ and <2 h/d), and heavy Internet users (HIUs) (${\geq}2$ h/d). Health factors included eight health risk behavior indices, four mental health indices and six physical health indices. Results: The distribution of Internet use was as follows: NIUs 17.4%, OIUs 68.1%, MIUs 12.7%, and HIUs 1.7%. In multivariate analysis, using OIUs as a reference, U- or J-shaped associations were observed for five health risk behavior indices (current smoking, current drinking, drug abuse, sexual intercourse, sedentary behavior on weekdays) and four mental health indices (stressed, depressed, suicidal ideation, attempted suicide) in both genders. After removing confounding effects, including age, region, school type, subjective school record, subjective economic status, presence of parents, living with family, and sedentary behavior, these associations were still observed. Conclusions: Health professionals should consider both Internet non-users (for non-educational purposes) and heavy users to be high-risk groups in terms of health status. Also, more well-designed studies are needed to clarify what factors are working in these nonlinear associations.
