This study aimed to investigate the associations between various types of childhood trauma and suicidal behavior in the general population in South Korea. This mental health survey included a total of 1,490 general citizens living in a metropolitan South Korean city who completed a questionnaire that assessed respondents’ histories of childhood trauma before the age of 12 years, including bullying victimization, emotional abuse, sexual abuse, and physical abuse, as well as suicidal behavior, including current suicidal ideation and histories of suicide planning and attempts. The following psychiatric scales were administered: Hospital Anxiety and Depression Scale (HADS), Rosenberg Self-Esteem Scale (R-SES), Connor-Davidson Resilience Scale (CD-RISC), Perceived Stress Scale (PSS), and visual analogue scale of EuroQol 5D (EQ-5D). Participants who experienced any childhood trauma had significantly higher HADS and PSS scores, and significantly lower EQ-5D scores. Additionally, participants with any type of childhood trauma were significantly more likely to have current suicidal ideation and histories of planned and attempted suicide. Multivariate analyses adjusted for confounding variables indicated that bullying victimization and sexual abuse were associated significantly with all types of suicidal behavior. Physical abuse was associated significantly with histories of suicide planning and attempts. The present findings showed that any type of childhood trauma was associated with higher levels of suicidality, anxiety, depression, and perceived stress, as well as lower health-related quality of life, in the general population. In particular, associations between childhood trauma and suicidality were identified after adjustment for confounding variables.

Background: This study evaluated the practicability of the suicide rate reduction target set by the current national suicide prevention policy in Korea, the fifth Master Plan for Suicide Prevention (2023–2027). This policy aims to lower the suicide rate from 26/100,000 in 2021 to 18.2/100,000 by 2027. Methods: We utilized monthly suicide statistics data from 2011 onwards. Using Bayesian regression and Autoregressive Integrated Moving Average (ARIMA) models, we conducted interrupted time series analyses to estimate the effect of the previous policy, the National Action Plan for Suicide Prevention (2018–2022), on suicide rates. We assumed this as the additional suicide reduction expected from the current policy. We generated point predictions and simulations for suicide rates from 2023 to 2027 using Bayesian regression and ARIMA models. Results: The interrupted time series analyses did not reveal a significant reduction in suicides attributable to the previous policy. Point predictions from the two models indicated that the suicide rate would remain approximately 24/100,000 in 2027. Almost all of the simulations of the 2027 suicide rate did not meet the policy target of 18.2/100,000. Conclusion The findings suggest that the Korean government’s suicide rate reduction target for 2027 is likely unattainable based on current trends and the limited effectiveness of previous policies. The objectives of suicide prevention policies should be evidence-based, attainable, and accountable.

Objectives: This study examined the shifts in the suicide trends in Korea during the initial phase of the Fifth Master Plan for Suicide Prevention, using interrupted time series analyses. Methods: Interrupted time series analyses were performed using the monthly suicide data from January 2011 to April 2024. Quasi-Poisson regression models were applied to evaluate the changes in the level and slope of the suicide trend before and after policy implementation. The Autoregressive Integrated Moving Average (ARIMA) and Prophet models were used to compare the actual and predicted counterfactual numbers of suicides during the policy period. Results: The quasi-Poisson regression model revealed a significant change in the trend of suicides among men, with an increasing slope during the policy period. For total suicides, the ARIMA and Prophet models suggested that the actual number of suicides was significantly higher than the counterfactual number during the policy period, with excess suicides averaging between 113 and 150 per month. The actual number of suicides among men was significantly higher than the counterfactual number during the policy period, with excess suicides averaging between 86 and 92 per month. No significant changes in the suicide trends among women were observed. Conclusion These findings suggest that the initial effects of the Fifth Master Plan for Suicide Prevention were inadequate to curb the rising suicide trends, particularly among men. This study underscores the need for timely policy responses to reverse the current increasing trend in suicides, with particular focus on the male population.

Objectives: This study was performed to identify factors associated with self-perceived depression among Korean adolescents during the coronavirus disease-2019 (COVID-19) pandemic. Methods: A total of 1,710 middle and high school students (54.7% boys, 45.3% girls) participated in a cross-sectional survey. The self-administered questionnaire included items assessing the changes in perceived depression and daily life patterns during the COVID-19 pandemic. Other questionnaires included sociodemographic data, three item version of the UCLA Loneliness Scale, Gratitude Questionnaire-6, and Big Five Inventory-10. Multivariable logistic regression was used to examine the factors associated with increased perceived depression during COVID-19 pandemic. Results: The prevalence rate of perceived depression was 18.4%. The multivariate logistic regression analysis revealed that high loneliness, neuroticism, decreased social relationships, increased familial conflict, increased internet using time, irregular meal pattern, and high perceived academic stress were significantly associated with perceived depression. Conclusions Our findings suggest that interventions aimed at coping with stress and regulate perceived depression due to sudden life style changes are necessary for adolescents, as such a global situation like COVID-19 pandemic could be prolonged or repeated.
