Purpose: The purpose of this study was to identify the experiences of depression, suicidal thoughts, and habitual drug use in middle and high school students and examine their relationship with the oral symptoms experiences. Methods: The participants of this study were 54,948 middle and high school students who took the screening and health survey at the 16th "Youth Health Behavior Survey" (2020). The SPSS statistical software (IBM SPSS 23.0 for Windows; IBM) was used for data analysis. The significance level was set to 0.05. Results: Complex-sample logistic regression analysis was performed to confirm the relationship between the experiences of depression, suicidal thoughts, and habitual drug use and oral symptom experienced. The results indicated that the absence of depression, suicidal thoughts, or habitual drugs had a significant effect on oral symptom experience. Conclusion: A systematic counseling program for early detection of oral symptoms and oral health promotion as well as strategies for practicing correct oral hygiene are required. Additionally, it is necessary to develop a customized education program to promote health education in middle and high school students. It can be used as the basis for an integrated support system that students can use to grow healthy. A differentiated program on the topic of mental health promotion for each grade can be planned and its effects can be monitored.

Suicide is a leading cause of death worldwide, especially among adolescents and young adults. Considering this fact, it is imperative that we understand the neural mechanisms underlying suicidal thoughts and behaviors in youth from a neurodevelopmental perspective. In this review, we focused on the magnetic resonance imaging studies that examined the neural correlates of suicidal ideations (SI) or attempts (SA) in youth. We reviewed twenty-three cross-sectional studies reporting the structural and functional alterations in association with SI or SA among adolescents and young adults with various mental disorders. The previous literature suggests that the dorsolateral prefrontal cortex, anterior cingulate cortex, and ventral frontolimbic circuit, may play an important role in the pathophysiology of suicidal behavior in youth through altered top-down control over emotion and impulsivity. Future studies with a longitudinal design and using multimodal imaging techniques may be of help to identify novel therapeutic targets specific for youth with suicidal thoughts and behaviors.

Objectives: This study attempted to determine the influence of factors related to suicide attempts in the elderly. Data from a 2017 Community Health Survey were used to find 67,810 subjects aged 65 years or older. Methods: Cross-analysis and logistic regression analysis were conducted by dividing the suicide thought and suicide attempt experience groups. Results: In the group with subjective stress, suicidal thoughts were higher in women 2.748 times (p<0.01) and 1.917 times (p<0.001) in women. In terms of income level, the higher the income level, the lower the suicidal ideation experience. Suicide attempts were 0.708 times lower when mastication was not uncomfortable and 0.170 times lower when the patient was not experiencing depression (p<0.001). Conclusions: The correlation between oral dysfunction and suicidal thoughts and attempts in the elderly has been demonstrated, and it is expected to be used as baseline data for establishing an institutional study.

The study aimed to find out to what degree suicidal thoughts and associated factors affect the suicide risk of advanced cancer patients. The frequency of suicidal thoughts among patients with cancer, especially in the advanced stages, is about 3 times greater than the adult average in South Korea. We recruited 457 participants with four types of cancers (colon, breast, cervical, and lung) using stratified sampling. Data collection was carried out through one-on-one interviews by trained nurses using a structured questionnaire. Advanced cancer patients with high, vs. low, levels of anxiety and pain had a higher suicide risk. In contrast, having one's spouse as the primary care provider was associated with a low suicide risk. Overall, the three factors of anxiety, pain, and the primary caregiver being one's spouse explained 17.2% of the variance in suicide risk. In conclusion, we derived influencing factors of suicide risk using a sample of patients with various types of advanced cancer. The results provide systematic baseline data for preparing nurse-led interventions to prevent suicidal thoughts and suicide attempts among advanced cancer patients.

Purpose: The purpose of this study was to investigate the effect of exercise on mental health in female elementary school teachers. Methods: The subjects were 1,861 female elementary school teachers in Seoul. Data were collected through an online survey from November 16 to December 7, 2008. Collected data were analyzed by descriptive statistics, ${\chi}^2$-test, t-test, one way ANOVA and Scheff$\acute{e}$ test, using IBM SPSS 20.0 program. Results: Not many female elementary school teachers were engaging in exercise. Even though their perception of stress and degree of depression were high, the rate of suicidal thoughts were low. The perception of stress was lower in the female teachers who engaged in walking or high-intensity workout than those who did not. The teachers who walked or stretched for exercise showed a lower rate of depression than those who did not and the teachers who walked for exercise displayed a lower rate of suicidal thoughts. Conclusion: Exercise programs should be provided for female elementary school teachers to reduce their stress, depression, and suicidal thoughts.

This study used the raw data of the 15th (2019) Korean Youth Health Risk Behavior Survey to investigate the risk factors of the health-risk behaviors of Korean multicultural adolescents on the subjective oral symptoms. The scope of the multicultural family was limited to children of immigrant women's families married to Korean men and immigrant male families married to Korean women, and 572 were selected as the final study subjects. The sociodemographic variables were surveyed as gender, grade, economic level, and school performance. The health risk behaviors included drinking, smoking, medication, stress, sleep satisfaction, suicidal thoughts, depression, and brushing before bedtime. The oral symptoms examined were toothache, gum pain, and halitosis. As a result, toothache was related to drinking, toothbrushing before sleep, stress, sleep satisfaction, suicidal thoughts, and depression. Gum pain was associated with drug use, sleep satisfaction, suicidal thoughts, and depression. Halitosis was associated with medication, brushing before sleep, stress, suicidal thoughts, and depression. In terms of health risk factors, drinking, stress, and sleep satisfaction were risk factors for toothache. Smoking, sleep satisfaction, and suicidal thoughts were risk factors for gum pain. The presence of toothbrushing and stress were risk factors for halitosis. In conclusion, a policy system is needed to support oral health education programs nationally at times, such as after-school activities or club activities, to promote oral health for teenagers.

This study investigated factors that affect stress recognition, depression, suicidal thoughts and health-related quality of life for diabetics over 50 years of age. Five hundred one diabetics were surveyed who participated in the 4th Korea National Health and Nutrition Examination Survey 2009. The data were analyzed with multiple regression analysis and Structural Equation Model to determine the factors. The results are as follows. Men, older and lower income groups, those not involved in economic activities, smokers, and drinkers showed a lower quality of life (p<0.001). There was no correlation with moderate-intensity exercise. Stress recognition (t=-4.229, p<0.001), depression (t=-2.156, p<0.05), and suicidal thoughts (t=-3.274, p<0.001) had significant effects on the quality of life (p <0.001, $R^2=0.25$). The most important of these factors is stress. Being diagnosed as a diabetic changes the lives of patients, who come under stress from controlling their blood sugar level. Societal support should be developed to help patients cope with the challenges of diabetes.

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.

This study developed models using decision forest, support vector machine, and logistic regression methods to predict and prevent suicidal ideation among Korean adolescents. The study sample consisted of 51,407 individuals after removing missing data from the raw data of the 18th (2022) Youth Health Behavior Survey conducted by the Korea Centers for Disease Control and Prevention. Analysis was performed using the MS Azure program with Two-Class Decision Forest, Two-Class Support Vector Machine, and Two-Class Logistic Regression. The results of the study showed that the decision forest model achieved an accuracy of 84.8% and an F1-score of 36.7%. The support vector machine model achieved an accuracy of 86.3% and an F1-score of 24.5%. The logistic regression model achieved an accuracy of 87.2% and an F1-score of 40.1%. Applying the logistic regression model with SMOTE to address data imbalance resulted in an accuracy of 81.7% and an F1-score of 57.7%. Although the accuracy slightly decreased, the recall, precision, and F1-score improved, demonstrating excellent performance. These findings have significant implications for the development of prediction models for suicidal ideation among Korean adolescents and can contribute to the prevention and improvement of youth suicide.

This study examined the mental health-related factors of Korean adolescents, especially focusing on the influence of internet use. This study analyzed the raw data from the 14th Korea Youth Risk Behavior Survey, 2018. The study population was 60,040, with 50.7% male students and 49.3% female students, and 49.7% high school students and 50.3% middle school students. The dependent variables were stress, sadness and despair, suicidal ideation, suicidal plan, and suicidal attempt. The independent variables were gender and age, health behaviors, and time using the internet. Logistic regression analysis was applied to derive the related factors. For all dependent variables, the main contributing variables were gender, grade, economic status, and academic performance. The mental health of adolescents was related to various factors. In particular, the time using the internet was linearly related to the degree of stress, and a higher student group of time using the internet had a more significant effect on sadness, despair, suicidal thoughts, and suicidal plans. In conclusion, the time using the internet has harmful effects on the mental health of Korean adolescents.
