This study examined the associations of physical activity by intensity with depression and suicidal thoughts among middle school students in South Korea. This study used data from the Survey of Korean Youth Health Risk Behavior. The samples were middle school students (Total 37,420). Logistic regression analysis were used. For depression, 33% of males and 43% of females felt depressed, whereas 17.8% of males and 27.7% of females experienced suicidal thoughts. In regression, both moderate physical activity and vigorous physical activity were associated significantly with a lower incidence of depression. In suicidal thoughts, moderate physical activity was associated with a lower incidence of suicidal thoughts among female students. In path analysis, vigorous physical activity had a direct and indirect effect on depression and suicidal thoughts. Physical activity is a potential mediator in decreasing depression and suicidal thoughts among middle school students.

In the super-aged societies, an increased elderly population living in solitude has been causing many problems. Since the elderly may incur a sense of loss and interest in suicide when living alone, this study investigated the effects of smartphones as well as types of living arrangements on elderly peoples' sense of loss and suicidal thoughts. This study found social roles and relationships were lower for older individuals using smartphones than those using 2G phones. Not surprisingly, those living with family members or a partner had significantly fewer suicidal thoughts than those living in solitude. However, our results indicate subjects' loss of role and relationships was affected more significantly by their smartphone usage (2G phone vs. smartphone) rather than their living arrangements (i.e., living with family or a partner vs. living in solitude). Moreover, smartphone users showed a lower sense of loss in terms of social roles and relationships. Among the elderly, loss of health, social role, and relationships were identified as precedents for increased suicidal thoughts; yet, economic capacity was surprisingly not an indicator of suicidal thoughts.

This paper reviews the global effect of the coronavirus disease 2019 (COVID-19) pandemic on the mental health of children and adolescents in South Korea, the U.S., Japan, and China. We reviewed research on deteriorated mental health, including increased suicide, suicidal thoughts, and self-harm. Various studies have shown that students' mental health issues, such as depression and anxiety, have worsened during the COVID-19 pandemic. Furthermore, the number of students who committed suicide has significantly increased in the U.S. and Japan. Factors such as prior mental health status, change in daily routine, reduced physical activity, excessive screen time, overuse of electronic devices, and reduced social support have been reported to have a significant effect. The chain of deteriorating mental health among the youth began at the onset of COVID-19, social distancing, and school closure. As youths began to stay at home instead of going to school, they lost opportunities to connect with their friends or teachers, who could provide support outside of their homes. Young people spent less time on physical activity and more time online, which damaged their sleeping schedule and daily routine. In preparing for the post-pandemic phase, we should thoroughly analyze the long-term effects of the pandemic on youth mental health, while simultaneously tackling current imminent issues.

The purpose of this study is to identify the double mediating the effects of social support and self-esteem in the relationship between the subjective social class and the suicide thoughts of middle aged men and women. The subjective social class was analyzed in a parallel double-mediated model to check the mediating effect of self-esteem and social support on the idea of suicide. Social support and self-respect, which are mediating variables of subjective social class on suicide idea, both were a statistically significant. Putting the results of this study together, it is essential to establish a living-based social support system for middle-aged adults. This will contribute to improving self-esteem among middle-aged adults.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

This study explores supportive and conflictual network structures of elderly single and couple households and analyzes the effects of supportive and conflictual networks on suicidal thoughts by gender and family type. The analysis considered a sample of 522 individuals over the age of 60 who did not live with their adult children. The statistical methods used to analyze data were descriptive statistics, a t-test, a chi-square test and a regression analysis using SPSS WIN 20.0. The results are as follows. First, men and elderly single households had support networks that were smaller than those of women and elderly couple households. The conflictual network of elderly couples households was larger than that of elderly single households. In addition, the larger the network, the more the conflictual was. Second, elderly single households thought about suicide more often than elderly couple households. Third, economic status, the number of adult children, the size of conflictual network and subjective health had considerable influence on suicidal thoughts of elderly single and couple households. The size of the conflictual network had a greater effect on suicidal thoughts of elderly individuals than that of the supportive network. These results have important policy implications for elderly single and couple households.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.
