This study aimed to investigate gender differences in prevalence and correlates of depression and suicidal ideation among Korean adolescents. The analysis was performed using data from the 2009 Korean Youth Risk Behavior Web-based Survey. Logistic regression models and Wald chi-square statistics were used to identify the difference in the coefficients between the gender-specific models. Female students reported higher prevalence for depression(42.9%) than male students(31.4%), as well as higher level of suicidal ideation(girls:23.1%, boys:14.7%). Lower school achievement, worse self-rated health status, more conflicts were associated with higher level of depression and suicidal ideation. The impact of school achievement and conflicts with friends on mental health was greater among girls than boys. We suggest that the efficient strategies focusing on the gender differences should be established to improve mental health among Korean adolescents.

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.

Background: Many patients with complex regional pain syndrome (CRPS) have been known to be at risk of suicide, due to severe pain and its comorbid conditions. The risk of suicide may be associated with affective instability, which is an indicator of emotional dysregulation. Particularly, unstable shifts in negative emotions are difficult to cope with, which may result in individuals feeling uncontrollable, hopeless, and entrapped. This study aimed to examine the role of affective instability in the relationship between pain intensity and suicide risk (suicidal ideation and impulsivity) in patients with CRPS, by employing a daily diary. Methods: Twenty-three patients registered at the CRPS Association in Korea were asked to complete a day-to-day routine for 15 days, followed by a diary composed of pain intensity, suicidal ideation, impulsivity, and positive and negative affects. Results: Results showed that the interactions between negative affective instability and daily pain intensity were statistically significant on daily suicidal ideation (coefficient = 0.41, t (21) = 2.56, P < 0.050) and daily impulsiveness (coefficient = 1.20, t (19) = 3.35, P < 0.010). However, those between positive affective instability and daily pain intensity were not. Conclusions: This study is the first attempt to investigate the role of affective instability on the relationship between daily pain intensity and daily suicide risk in patients with CRPS. Our findings suggest that health professionals pay considerable attention to the instability of negative affects when assessing and managing patients with CRPS at risk of suicide.

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.

Object : Nerve growth factor(NGF) is a protein involved in neuronal survival and plasticity in the central nervous system, which might play an important role in stress, depression and suicide. This study was performed to determine whether there is an alteration in plasma NGF concentrations in depressed patients with suicidal attempt. Methods : The subjects were 32 depressed patients who attempted suicide and admitted in emergency room. Forty-four hospitalized non-suicidal depressive patients and the 30 normal controls were closely matched with the suicidal group in terms of age and sex. Individuals in all 3 groups were evaluated independently by a semi-structured interview for the purpose of establishing a DSM-IV criteria diagnosis. The severity of depressive symptoms was evaluated using Hamilton depression rating scale(HDRS). The severity of the suicidal behavior was evaluated by Weisman and Worden's risk-rescue rating(RRR) system and the Lethality Suicide Attempt Rating Scale(LSARS). Plasma NGF level was measured by the enzyme linked immunosorbent assay(ELISA) method. Results : There were no statistically significant differences of the plasma NGF levels among groups. LSARS and RRR did not reveal any significant correlation with ${\beta}$-NGF level in suicidal depressive patients. Conclusion : This study do not support an association between ${\beta}$-NGF and suicidal depression. However it is necessary to investigate this association through other route such as postmortem brain.

Objective : The suicide mortality rate among Koreans was ranked first among the OECD countries in 2018. Alcohol consumption is a significant risk factor for suicidal behavior. This study examined the relationship between the severity of subjects' drinking habits and the suicidal ideation among Koreans according to gender and age. Methods : The data of 113,602 people who visited the Kangbuk Samsung Hospital Health Screening Center from January 2013 to December 2014 were used. The severity of subjects' harmful drinking habits was assessed using the Korean version of the Alcohol Use Disorders Identification Test (AUDIT-K). The relationship between the severity of harmful drinking and suicidal ideation was compared using logistic regression analyses. We also examined the tendency through p for trend to identify a trend. Results : Of the 113,602 study subjects, 6,586 (5.8%) responded that they had thought of committing suicide. After controlling for gender, marriage, education, body mass index (BMI), depression and anxiety, the results showed that the higher the level of harmful drinking, the higher the suicidal ideation. Conclusion : This study found that, even after controlling depression and anxiety, the severity of drinking could be a significant risk factor for suicidal ideation.
