Objectives: This study explored the relationship between physical activity, generalized anxiety disorder, and suicidal risk among South Korean adolescents, considering individual characteristics. Methods: The study analyzed raw data from the 2023 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. A total of 52,880 adolescents’ data (weighted to 2,581,964) were analyzed using a complex sample design. Results: Physical activity level had a negative effect on anxiety. Anxiety had a positive effect on suicidal risk, including thoughts, plans, and attempts. Physical activity level indirectly affected suicidal risk negatively by mediating anxiety. Individual characteristics such as gender, alcohol consumption, smoking, drug use, and household economic status also influenced suicidal risk. Conclusions: This study emphasizes that effectively reducing adolescent suicide rates requires a multifaceted approach. Such an approach should include promoting physical activity, addressing mental health challenges like anxiety, and providing tailored support for vulnerable populations. Full article

Background: Benzodiazepine poisoning is a frequent cause of emergency department (ED) visits, often related to suicide attempts. Flumazenil is the only specific antidote, but its continuous infusion protocol remains controversial because of its uncertain outcome benefits and increased risk of adverse events. This study aimed to evaluate the effect of continuous flumazenil infusion on the time to recovery of consciousness and secondary outcomes in patients with benzodiazepine poisoning stratified by hospitalization status. Methods: A retrospective cohort study was conducted at a tertiary hospital in Seoul, Korea, including adults treated for benzodiazepine poisoning in the ED between April 2019 and March 2024. The primary outcome being the time from arrival at the ED to regaining consciousness. Multivariate regression identified independent predictors of delayed recovery. Results: Among the 370 patients, 52.4% were hospitalized. Flumazenil infusion was administered in 46.8% of the patients, more often in hospitalized patients. In this group, flumazenil infusion significantly reduced the median time to regain consciousness (13.7 vs. 19.4 h, p = 0.006) but did not affect the overall hospital stay. In nonhospitalized patients, flumazenil infusion did not shorten the awakening time or prolong the ED stay. Adverse events, mainly agitation, were more frequent with flumazenil infusion. Conclusions: Continuous infusion of flumazenil accelerates the recovery of consciousness only in hospitalized patients who are severely affected by benzodiazepine poisoning but with increased adverse events and no reduction in hospital stay. Individualized patient selection and evidence-based protocols are needed for optimal and safe antidote use. Full article

Background/Objectives: The rising prevalence of mental health disorders among adolescents underscores the need for early intervention. Of concern is the increasing consumption of sugar-sweetened beverages (SSBs) and high-caffeine drinks, which may adversely affect adolescent mental health. This study examined their association with stress perception, depressive symptoms, suicidal ideation, and loneliness among Korean adolescents. Methods: Data were derived from the 2022 Korea Youth Risk Behavior Survey, a nationally representative dataset comprising 51,850 Korean adolescents aged 12–18 years. Beverage consumption frequency was categorized into three groups: none, 1–4 times per week, and ≥5–6 times per week. Logistic regression models were employed to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for mental health conditions, adjusting for potential confounders. Results: Compared with non-consumers, adolescents who consumed SSBs ≥5–6 times per week exhibited significantly higher odds of stress perception (AOR 1.35, 95% CI 1.24–1.46), depressive symptoms (AOR 1.32, 95% CI 1.19–1.46), suicidal ideation (AOR 1.23, 95% CI 1.09–1.39), and loneliness (AOR 1.44, 95% CI 1.28–1.61). Similarly, frequent consumption of high-caffeine drinks (≥5–6 times per week) was associated with increased odds of stress perception (AOR 2.13, 95% CI 1.99–2.29), depressive symptoms (AOR 1.75, 95% CI 1.62–1.88), suicidal ideation (AOR 2.04, 95% CI 1.86–2.24), and loneliness (AOR 1.72, 95% CI 1.59–1.87). Conclusions: Frequent consumption of SSBs and high-caffeine drinks is significantly associated with adverse mental health outcomes among Korean adolescents. Given the increasing intake of these beverages, targeted public health interventions are warranted to mitigate their potential negative impact on adolescent mental well-being. Full article

Background: This study aimed to evaluate the association between physical activity and suicidal ideation in adult women and to examine the moderating effect of self-rated health status. Methods: This study utilized raw data from the Korea National Health and Nutrition Examination Survey (KNHANES) from the 6th to the 8th cycle (2013–2021). Complex sample logistic regression analysis was performed to assess the association between physical activity and suicidal ideation, and stratified analysis was conducted to examine differences in effects according to self-rated health status. Results: The prevalence of suicidal ideation among participants was 5.5%. Stratified analysis revealed that the effect of physical activity on suicidal ideation varied by self-rated health status. Among women with good self-rated health, physical activity was associated with significantly reduced odds of suicidal ideation (OR = 2.116, 95% CI: 1.229–3.643). However, among those with fair or poor self-rated health, physical activity showed no significant protective effect (OR = 1.173, 95% CI: 0.902–1.525). Conclusions: This study demonstrates a significant association between physical activity and suicidal ideation, with self-rated health status playing a key moderating role. Suicide prevention strategies should incorporate interventions that promote physical activity while considering self-rated health status. Full article

Background: Unhealthy lifestyles constitute significant risk factors for adolescent suicide, and their detrimental effects may persist from adolescence into adulthood. This research study sought to examine how Body Mass Index (BMI), alongside various lifestyle behaviors among teenagers in Korea, correlates with suicidal thoughts, the formulation of suicide plans, and actual suicide attempts. Methods: The research examined unprocessed information collected during the 2022 Korean Youth Risk Behavior Web-based Survey (KYRBS), which was administered by the Korea Disease Control and Prevention Agency (KDCA). Lifestyle factors associated with suicidal behavior were selected as independent variables. The sample was stratified according to BMI for further analysis. Logistic regression models were applied to assess the association between lifestyle factors and the risk of adolescent suicide. Results: The analysis identified significant correlations between unhealthy dietary patterns, hazardous drinking behavior, smoking, and a sleep duration of less than 5 h, all of which were associated with a heightened suicide risk among adolescents. Notably, underweight adolescents who had a sleep duration of less than 5 h demonstrated a markedly elevated risk of suicidal ideation (OR = 2.391, 95% CI [1.035–5.525]). Among overweight adolescents, frequent coffee consumption was significantly associated with both suicidal planning (OR = 1.850, 95% CI [1.133–3.020]) and suicide attempts (OR = 1.958, 95% CI [1.024–3.742]). Importantly, hazardous drinking behavior was strongly associated with suicide attempts (OR = 2.277, 95% CI [1.132–4.580]). Non-smoking behavior exhibited a significant relationship with a decreased likelihood of suicidal ideation (OR = 0.706, 95% CI [0.507–0.983]) and suicidal planning (OR = 0.528, 95% CI [0.299–0.930]). Furthermore, among obese adolescents, non-smoking behavior significantly decreased the risk of suicidal ideation compared to smoking (OR = 0.514, 95% CI [0.297–0.887]). Conclusions: The study revealed that the combined impact of unhealthy behaviors—smoking, eating an unhealthy breakfast, sleeping for less than 5 h, and hazardous drinking behavior—significantly affect suicide-related behaviors in adolescents. The interaction between BMI and lifestyle factors is a critical determinant of these behaviors. Specifically, sleep health exerts a substantial influence on suicide-related behaviors in underweight adolescents, while smoking strongly correlates with suicidal behaviors in overweight and obese adolescents. Targeted attention to the interplay of smoking, diet, sleep, and alcohol consumption with BMI is crucial for the early detection and prevention of adolescent suicide. Full article

Background/Objective: South Korea continues to have the highest suicide rate among the Organization for Economic Co-operation and Development (OECD) countries, with a growing number of emergency department (ED) admissions related to self-harm and suicide attempts. However, trauma-focused analyses that integrate psychiatric profiles and suicide mechanisms remain limited, hindering effective clinical care and preventive strategies. Methods: This retrospective study analyzed trauma patients who presented to the ED of Wonju Severance Christian Hospital following suicide attempts between October 2015 and December 2023. Of 305 self-harm cases, 208 survivors who underwent psychiatric evaluation were included. The variables analyzed included the mechanism, site, and severity of injury (ISS and AIS); psychiatric diagnosis and prior psychiatric history; repeated suicide attempts; alcohol use; physical pain; interpersonal conflict; and economic vulnerability. Chi-square, Fisher’s exact, and Kruskal–Wallis’ tests were used for statistical comparisons. Results: Stabbing/cutting (56.7%) and falling (35.6%) were the most common attempts. Mood disorders were the predominant psychiatric diagnosis (63.9%), followed by adjustment disorders (26.0%), alcohol use (25.5%), and psychotic disorders (22.1%). Among the fall-related cases, patients were typically younger and predominantly women. The median ISS was highest in fall-related cases (17) compared with stabbing/cutting (4), with 25.96% of patients with an ISS ≥16, indicating severe trauma. A psychiatric history was associated with a higher incidence of falls (44.3%), and previous suicide attempts correlated with the use of high-lethality attempts. Severe physical pain was linked to stabbing/cutting in 10 of 11 cases. Interpersonal conflict was more frequently associated with stabbing/cutting (59.6%) than with falls (31.9%). No significant association was found between alcohol use and the method of suicide attempt. Conclusions: The suicide mechanisms in patients with trauma are closely associated with psychiatric and psychosocial factors. Stabbing/cutting is often impulsive and driven by interpersonal conflict or alcohol use, while falling is more frequent in patients with psychiatric histories of repeated attempts. These findings emphasize the importance of mechanism-informed psychiatric evaluations and trauma protocols. Regionally adapted, interdisciplinary approaches and early psychiatric intervention are crucial for effective post-attempt management and suicide prevention. Full article

(1) Objectives: This study aimed to investigate the intervention effects of physical activity and sedentary behavior on the relationship between various influencing factors and mental health outcomes in the elderly. (2) Methods: Complied data collected from a nationwide survey conducted between 2013 and 2022 were analyzed using the X-Learner algorithm to explore these relationships. (3) Results: The findings indicate that engagement in both high- and moderate-intensity physical activities leads to statistically significant improvements in depression, suicidal ideation, and stress levels compared to non-participation. (4) Conclusions: The study emphasizes the essential role of physical activity in enhancing the mental health of the elderly in South Korea, demonstrating that high- and moderate-intensity exercise can effectively reduce depression, suicidal thoughts, and perceived stress. It also highlights the detrimental effects of prolonged sedentary behavior on the mental health of older adults. Full article

Background/Objectives: This study identified the risk of habitual substance use among multicultural adolescents, focusing on health behavior characteristics and cultural differences based on their mother’s country of origin. Methods: This secondary data analysis used data from the 18th (2022) and 19th (2023) Korea Youth Risk Behavior Web-based Surveys, which are repeated cross-sectional surveys conducted annually. The analyses of 82,520 adolescents included descriptive statistics, the Rao–Scott χ² test, and logistic regression. Results: The prevalence of habitual substance use among multicultural adolescents whose mothers were from the examined countries was 2.01%, which is 0.74 percentage points higher than the 1.27% prevalence observed among adolescents with Korean mothers. Among multicultural adolescents, the risk of habitual substance use was higher under specific conditions: those with Chinese mothers faced increased risks when not living with family (OR = 6.22) or smoking (OR = 12.65); Korean-Chinese adolescents had higher risks when experiencing suicidal ideation (OR = 3.41) or anxiety (OR = 8.17); and those with Vietnamese mothers were at greater risk when exposed to violence (OR = 12.42) or depression (OR = 14.06). These results underscore the role of cultural and psychological factors in adolescent substance use. Conclusions: Our findings revealed differences in risk factors based on the mother’s country of origin. These results underscore the importance of understanding adolescents’ unique characteristics and developing tailored intervention strategies that account for these cultural and familial differences.

Background: Caffeine, a widely consumed stimulant, affects sleep and mental health. Shift work disrupts the circadian rhythm and has been associated with various mental health issues, such as depression, anxiety, and suicidal ideation. Objective: This study explored the associations between caffeine consumption, sleep duration, and mental health outcomes, particularly suicidal ideation, among shift workers in Korea. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey (2013, 2015), which comprised 4723 adults aged 19 and older, were analyzed. Participants were categorized into groups based on average daily coffee consumption and work patterns. Multiple logistic regression analyses were conducted to determine the impact of caffeine consumption and work patterns on mental health outcomes. Results: Participants worked longer hours, reported higher perceived stress levels, and slightly decreased sleep duration as daily coffee consumption increased. However, no significant differences were observed in depression or suicidal ideation across the coffee consumption groups. Logistic regression analysis indicated a trend towards higher suicidal ideation risk with increased coffee intake, particularly among those who consumed three or more cups per day (OR 5.67, 95% CI 1.82–17.59). Conclusion: This study suggests a complex relationship between caffeine consumption, work patterns, and mental health outcomes. Although caffeine intake is associated with increased work hours and stress, its impact on suicidal ideation is influenced by occupational factors. Full article

Firefighters across the world face higher risks of occupational hazards, such as exposure to chemicals, extreme heat, traumatic stressors, and intense physical demands, which can increase their vulnerability to a range of psychological and physiological difficulties. These challenges include the risk of developing chronic stress, depression, and post-traumatic stress disorder (PTSD), potentially leading to detrimental negative coping patterns such as alcohol abuse. The consequent health implications impact both short-term and long-term health and well-being. This study aimed to explore the relationship between mental health status, alcohol consumption patterns, and gut microbiome alterations in firefighters from two different regions—America and Korea. By investigating these relationships, we hope to gain insights into how repeated exposure to severe stressors impacts gut health. Healthy male firefighters (ages 21–50) and controls (matched sex, geography, and age) were recruited via flyers and snowball sampling in the United States and South Korea, resulting in 203 participants (102 firefighters and 101 controls). Firefighters reported significantly higher PTSD symptoms and depression and drank 2.3 times more alcohol than the control group. American firefighters reported more drinking than Koreans. There was a significant correlation between higher alcohol consumption and the likelihood of witnessing deaths by suicide. However, there were no correlations between alcohol consumption and PTSD symptom severity. There were associations between alcohol consumption patterns and aspects of the gut microbiome. This study highlights the mental health challenges faced by firefighters, including elevated rates of PTSD, depression, and alcohol consumption, with specific microbial imbalances linked to PTSD and alcohol use, emphasizing the role of the gut–brain axis.

Background: Compliance with cancer screening guidelines is crucial for the early diagnosis and prevention of cancer. We explored the association of suicidal ideation with participation in cancer screening programs. Methods: This cross-sectional analysis included a nationwide sample consisting of 22,554 Korean adults (9667 men and 12,887 women). Suicidal ideation in the past year was self-reported (yes or no). Participation in gastric, colorectal, cervical, and breast cancer screening within the past 2 years was assessed. Logistic regression models were employed to determine the association of suicidal ideation with participation in each cancer screening test. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated. Results: Among men, the participation rates in gastric and colorectal cancer screening were 47.6% and 39.7%, respectively. Among women, the participation rates in gastric, colorectal, cervical, and breast cancer screening were 47.1%, 34.8%, 44.3%, and 50.8%, respectively. In the male sample, suicidal ideation was associated with reduced participation in gastric cancer screening (OR: 0.83, 95% CI: 0.69–0.99) and colorectal cancer screening (OR: 0.82, 95% CI: 0.67–1.00). Similarly, in the female sample, suicidal ideation was inversely associated with participation in gastric (OR: 0.74, 95% CI: 0.67–0.82), colorectal (OR: 0.71, 95% CI: 0.62–0.81), cervical (OR: 0.75, 95% CI: 0.68–0.84), and breast cancer screening (OR: 0.76, 95% CI: 0.68–0.84). Conclusions: This study suggests that individuals with suicidal ideation demonstrated reduced participation in cancer screening tests. This study highlights the need for targeted support to improve access to cancer screening programs for individuals with mental health problems. Full article

Since the COVID-19 pandemic, mental health challenges among children and adolescents in South Korea have intensified with rising rates of depression and suicide. Proactive interventions focusing on mental well-being are needed to address this critical issue. This study examines the effectiveness of the Mindfulness-based Social–Emotional Growth (MSEG) program for enhancing the mental health of elementary school students in Korea. This quasi-experimental study evaluated the impact of the MSEG program on students at an elementary school in Gyeonggi-do, South Korea. A total of 70 students (35 from lower grades [grades 1–3] and 35 from upper grades [grades 4–6]) participated in the 12-week intervention group, while 72 students were in the control group. Pre- and post-intervention assessments measured social–emotional, mindfulness, and clinical domains. The findings revealed significant improvements in emotional regulation across all grades. Lower-grade students showed substantially reduced anxiety and depression, while upper-grade students demonstrated enhanced resilience compared to the control group. These results indicate the potential of the MSEG program to promote early mental health when integrated into elementary school curricula. Further research is needed to adapt the program to diverse educational settings and optimize its effectiveness and impact. Full article

Background/Objectives: This study investigated the mediating effects of instrumental activities of daily living (IADL) and depression on the relationship between the ability to perform movements and death preparation among older adults with osteoarthritis (OA) or rheumatoid arthritis (RA). Methods: This study is a secondary analysis of data from the Ministry of Health and Welfare of Korea’s 5th (2020) survey of the elderly. It included 1483 elderly individuals with OA or RA. We measured the ability to perform movements, death preparation, IADL, and depression using validated scales. Hayes’ PROCESS Macro for SPSS model 6 was used to determine the mediating effects. Results: Death preparation exhibited significant differences based on satisfaction with economic conditions, fall experiences, and suicidal ideation. A significant correlation existed between the ability to perform movements, death preparation, IADL, and depression. IADL demonstrated a significant mediating effect between the ability to perform movements and death preparation. However, depression did not exhibit a significant mediating effect. Conclusions: IADL significantly mediates the relationship between movement ability and death preparation in elderly individuals with OA or RA. Lower movement ability was associated with higher death preparation and greater IADL dependence. However, contrary to expectations, depression did not show a significant mediating effect. These findings offer significant insights for developing interventions to enhance the quality of life and prepare for dignified death in elderly individuals with OA or RA. Future longitudinal studies are required to clarify the causal relationships and evaluate the efficacy of IADL enhancement programs. Full article

Background/Objectives: Adequate sleep is critical for adolescents’ physical and mental health. However, academic demands and lifestyle habits lead to insufficient sleep among many adolescents. This study examined the relationship between sleep patterns and general characteristics, health behaviors, and mental health among South Korean adolescents. Methods: Data were obtained from the Korea Youth Risk Behavior Survey conducted by the Korea Disease Control and Prevention Agency, involving 21,283 students aged between 13 and 18 years. Self-reported sleep duration was categorized as adequate (8–10 h) or insufficient (less than 8 h on both weekdays and weekends), and 20 independent variables across demographic, socioeconomic, lifestyle, health-related behavioral, and psychological factors were analyzed. Multiple logistic regression analyses were conducted to evaluate the effects of insufficient sleep. Results: Insufficient sleep was more prevalent among female students (odds ratio [OR]: 2.064) and older students (OR: 16.588 for Grade 12 vs. Grade 7) and was associated with higher stress levels (OR: 4.338 for almost always vs. never), suicidal ideation (OR: 1.826), and unhealthy behaviors such as alcohol consumption (OR: 2.009), smoking (OR: 1.998), and smartphone overdependence (OR: 2.313 for severe vs. normal). In contrast, adolescents with adequate sleep reported greater happiness (OR: 4.167 for very much vs. not at all) and better academic performance (OR: 1.377 for very high vs. very low). Conclusions: The findings show that insufficient sleep significantly affects adolescent well-being, highlighting the need for tailored interventions and increased societal awareness. Future research should explore the mechanisms underlying gender differences and weekday–weekend sleep disparities to enhance sleep quality in this population. Full article

This study examined the sequential mediating roles of anxiety and depressive symptoms in the effect of school bullying victimization on suicidal ideation. This study utilized a convenience sample of college students across South Korea, and an online survey was conducted. This quantitative research analyzed data collected from 1037 participants. The sample consisted of an equal gender distribution, with a mean age of 23.65 years (range: 18–30). Additionally, 30% of participants reported a household income of four million won or less (approximately USD $3076). More than half of the participants’ parents had attained a college education or higher. Also, multiple mediation analyses were conducted to examine whether anxiety and depressive symptoms mediated the relationship between school bullying victimization and suicidal ideation. In the results, multiple mediation analyses showed that school bullying victimization does not have a direct effect on suicidal ideation. On the other hand, school bullying victimization has an indirect effect on suicidal ideation through anxiety and depressive symptoms, controlling for covariates. Based on these research results, implications for school bullying prevention and intervention were discussed. Full article
