Data regarding 6512 families from the 2010–2021 Korean National Health and Nutrition Examination Survey were analyzed; among them, 428 were placed in the suicidal ideation (SI) group and 421 were placed in the matched control (MC) group. This number was selected for the use of the propensity score matching method. The findings highlighted significant associations between parental mental health and adolescent suicidal ideation, with mothers in the SI group having higher odds of Diagnosed Depression (OR 2.109, 1.023–4.350 95% CI), Depressive Mood (OR 2.155, 1.224–3.793 95% CI), and Suicidal Ideation (OR 2.532, 1.322–4.851 95% CI) compared to the MC group. Regarding the fathers, paternal Suicidal Ideation (OR 4.295, 1.747–10.599 95% CI) was the only significant factor for adolescent suicidal ideation. In contrast, maternal depressive symptoms and help-seeking behavior significantly impacted adole...

Methods：This study used data from the five-year-old Korea Welfare Panel and analyzed using questions about verbal and physical violence, depression and suicide ideation that were investigated every year. Age, education, and economic levels, drinking, religion, chronic disease, satisfaction with family relationship, satisfaction with social relationship, were included as variables. Results：The five-year cumulative score of verbal violence had a statistically significant effect on the depressive symptom, and the relative risk was 1.180. The relative risk of five-year-old cumulative score of verbal violence in suicidal ideation was 1.276, and it was also significant even if they exclude the effects of depressive symptom. On the other hand, the five-year cumulative score of physical violence was found to have no significant impact on suicide ideation if they excluded the effects of depressive symptom. Conclusions：Unlike previous studies, this study found that chronic verbal IPVs increase suicide ideation, even though they do not contain effects of depression. Such findings suggest that intervention in IPV in married women may help reduce the nation's suicide rate. KEY WORDS : IPV ㆍMarried women ㆍVerbal violence ㆍSuicidal ideation.

However, the characteristics of suicide attempters based on the emergency department (ED) have rarely been explored, making it challenging to comprehend the characteristics of youth suicide attempters comprehensively. This study aims to investigate the characteristics of youth suicide attempters who visited the ED. METHODS We examined the youth (age: 12-25 years) and adult (age: 26-65 years) groups of suicide attempters who visited the ED in Wonju-si, Gangwon-do, Korea. Interviews were conducted with attempters and guardians to identify sociodemographic, clinical, and suicide-related variables. Besides, we performed bivariate logistic regression analysis with statistically adjusted gender, educational age, Socioeconomic Status(SES) level, and medical illness. RESULTS Youth were diagnosed more frequently with Personality disorder compared to adults. Besides, youth tended to report interpersonal or abuse as motivations for suicide, whereas adults tended to report medical illness or economic problems. Furthermore, youth attempted suicide more impulsively and repeatedly; however, medical lethality of each attempt tended to be lower than adults. LIMITATION We experienced difficulty in collecting complete information because of poor consciousness or cooperation of patients who visited the ED immediately after suicide attempt. Also, the study cohort was only recruited from one hospital in a region. CONCLUSION Youth suicide attempters are suggested to have relatively serious and persistent problems involving personality or traits than adults. Thus, this study highlights the significance of preventive strategies based on early psychopathological evaluation and treatment.

The subjects in this study were 526 suicide attempters who visited emergency rooms in a teaching hospital in South Korea. Subjects were provided a continuous case management program with a flexible approach according to the severity of their suicide risk and needs. During the entire observation period (from 182 days to 855 days, mean = 572 ± 254), 18 patients (3.7%) died by suicide reattempt: Eight patients (2.27%) in the case management group and 10 patients (7.35%) in the no-case management group. The Cox regression analysis showed that the case management group had a 75% lower risk of death from suicide attempts than the no-case management group (HR = 0.34, 95% CI = 0.13–0.87). This result was shown to be more robust after adjusting for confounding factors such as gender, age, psychiatric treat...

From July 2015 to December 2017, 200 randomly selected Korean Farmers Cohort study participants were recruited and of these, 169 participants were analyzed. Pesticide exposure was investigated using a standardized questionnaire, and the Korean-Montreal Cognitive Assessment (K-MoCA) was conducted. Cognitive decline was more frequent among those directly exposed to pesticides (P = 0.057). Pesticide exposure and cognitive decline were positively correlated in the group with direct exposure versus no exposure (crude odds ratio [OR], 2.66; 95% confidence interval [CI], 1.17-6.04); this relationship was insignificant after adjustment (adjusted OR, 1.50; 95% CI, 0.57-3.92). There was a significant difference in the K-MoCA scores for each group based on pesticide exposure (P = 0.003). When we stratified by age, differences in the K-MoCA scores depending on the degree of pesticide exposure in the those aged 60 to 69 years were identified. Overall, there was a tendency towards an association between pesticide exposure and cognitive decline in rural Korean adult farmers. In our study, chronic pesticide exposure tended to have a greater impact in certain age group (60-69 years) than in those under 60 and over 70.

Data were obtained from the 2017 Korea Youth Risk Behavior Web-Based Survey, a nationally representative survey of middle- and high-school students (n = 62,276). The content type of smartphone use was divided into four categories: (1) Study, (2) Social-Networking Services (SNS), (3) Game, and (4) Entertainment. The association of depressive mood and suicidal ideation with content type of smartphone use was analyzed, using multiple and binary logistic regression analyses, respectively. The relationship between content type of smartphone use and time spent on smartphone use and problematic smartphone use was analyzed by using multiple logistic regression, adjusted for related covariables. The results of this study revealed that depressive mood and suicidal id...

In this study, we aimed to estimate the effectiveness of alcohol-related biochemical markers and Alcohol Use Disorder Identification Test Consumption (AUDIT-C) in suicide attempters who visited our ED based on the gold standard for clinical diagnosis used by psychiatrists for alcohol use disorder. Moreover, we aimed to search for a significant standard when clinicians make correct predictions about alcohol use disorder using these markers. Methods Among the subjects who visited ED following a suicide attempt, a total of 203 subjects were selected. Following a psychiatric interview, the subjects who met the criteria for alcohol abuse or alcohol dependence according to DSM-IV-TR in the past year were defined as the “alcohol use disorder” group. Although s...

Methods: This study included 149 children under the age of 18, and 1427 people in the age of 19-65 who came to the emergency department with suicide attempt from 2009 to 2015. We compare sociodemographic, clinical, and suicide attempt-related characteristics through Chi-square test and logistic regression analysis to evaluate the difference between two groups. Results: In adolescents, suicide attempters had more number of previous suicide attempt history than adults. Adolescents used more non-lethal method such as poisoning of over the counter drugs and had about 5 times higher odds ratio in suicide attempts with analgesics. The motivation of suicide attempt among adolescents was more related with interpersonal problems but less with financial or illness-related problems. The intention of suicide attempt in adolescents was less serious and lethal compared to adults.

Data were obtained from the 2017 Korea Youth Risk Behavior Web-based Survey, a nationally representative survey of middle-and highschool students (N = 62,276). Time spent using a smartphone was divided into four categories: less than 1 h, 1-2 h, 3-4 h, and 5 h or more a day. The association of conflicts with family due to smartphone use, conflicts with friends due to smartphone use, and poor academic performance due to smartphone use with suicide attempts and time spent using a smartphone were analyzed using multiple and binary logistic regression analyses, respectively. The relationship between time spent on a smartphone and suicide attempts was analyzed using a multiple logistic regression analysis. All analyses were also stratified according to the main purpose of smartphone use (process purposes/social purposes). Conflicts with family/friends due to smartphone use was significantly associated with suicide attempts (P <0.001). The variables of conflicts with family, conflicts with friends and poor academic performance were also proportionally related to higher smartphone use (P <0.001). The use of a smartphone was significantly associated with suicide attempts in a multiple logistic regression analysis (adjusted odds ratio for smartphone use 5 h or more a day 2.16; 95% CI 2.07-2.26; P <0.001), and the association was more prominent with smartphone use for process purposes. Conflicts with family, conflicts with friends, poor academic performance, and suicide attempts were related to higher smartphone use in Korean adolescents. Time spent on a smartphone was positively related to suicide attempts, even after adjusting for conflicts with family members or friends and poor academic performance due to smartphone use.

Methods Data pertaining to 691 suicide attempters who had visited an emergency center and had been followed-up from 2010 to 2015 were gathered. Participants were categorized into following three groups according to alcohol use pattern at the time of the suicide attempt: 1) suicide attempters with neither alcohol use disorder nor acute alcohol consumption (NAU), 2) suicide attempters who had used alcohol during the suicide attempt but did not have alcohol use disorder (AAU), and 3) suicide attempters with alcohol use disorder (AUD). Group comparisons and multivariate Cox proportional models for suicidal behavior were used for statistical analysis. Results AUD have been shown to have lower lethality of suicide attempt but higher risk of suicide reattempts in the future. Furthermore, positive relationships between suicide reattempts and AUD persisted throughout the longer period than other groups. Conclusion Suicide attempters with AUD should be considered a high-risk group for suicide reattempts in future, and this group should be followed-up for a longer period with specialized care program.

Here we developed a risk stratification model for adolescent suicide attempts using sociodemographic characteristics, risk behaviours and psychological variables. Participants were 247,222 subjects in the Korea Youth Risk Behavior Web-based Survey (KYRBS). We developed a suicide index based on the suicide risk estimated in the generalized linear model and proposed the risk stratification model using the R language to measure the probability of suicide attempt among adolescents. Among the study population, the annual rate of suicide attempt was approximately 4%. The model provided good prediction for suicide attempt (AUC = 0.85). The important univariate risk factors for the outcome were dimensional measures of age, sex, breakfast consumption, experience of violence, sleep duration, perceived stress, feeling of sadness, current cigarette smoking, current alcohol drinking, perceived general health...

Methods We analysed data from a nationally representative sample of Korean adolescents aged 12-18 years (n = 65,528). We investigated the risks of depressive symptoms, suicide ideation, plan and attempt in adolescent non-daily smokers using multiple logistic regression analyses after adjusting for confounding factors. Taking into account the trajectory of smoking patterns in adolescents, we assessed all analyses with stratification by early (aged 12-15) and late (aged 16-18) adolescents. Results Among early adolescents, non-daily smokers were more likely to have depressive symptoms, suicide ideation and plan compared with never smokers and even more likely to have depressive symptoms compared with daily smokers. Among late adolescents, non-daily smokers had higher risks of depressive symptoms, suicide ideation, plan and attempt than never smokers, whereas the risk for suicide attempts was lower than daily smokers. Conclusions Our findings suggest that non-daily smoking in adolescents was associated with risks for depressive symptoms and suicidal behaviours, and the association was more prominent in

We included consecutive series of 920 patients aged 45 years and older who had visited the emergency room from 2009 to 2015 because of suicide attempts. They were divided into 3 groups according to age. Information about the suicide attempt and sociodemographic status was gathered through interviews with attempters or caregivers. Chi-square test and logistic regression analysis were performed to evaluate the differences among the 3 groups. We found that old-old suicide attempters had high intent to die and high medical lethality as a result of the attempt, and illness-related problems exerted a strong motivational effect on this group. Psychiatric drugs, pesticides, and herbicides were frequently used to attempt suicide. These attempts were less likely to be associated with alco...

The aim of this study is to investigate whether delirium patients with psychotic symptoms (PS) would have unique clinical characteristics and outcomes. A retrospective chart review was performed on the patients with delirium due to general medical conditions to assess clinical characteristics and outcomes. All patients were assessed by Delirium Rating Scale-revised-98 and classified as having PS when scored two or more on at least one of the psychotic symptom items (perceptual disturbances, delusions, and thought process abnormalities). Of 233 patients with delirium, 116 (49.8%) manifested PS. Patients with PS were younger, more likely to use antipsychotics to manage delirium, and had more hyperactive motor subtype than patients without PS. Logistic regression analysis showed that odds ratio of psychotic symptoms for having...

Conclusions Our findings suggest that non-daily smoking in adolescents was associated with risks for depressive symptoms and suicidal behaviours, and the association was more prominent in

We included consecutive series of 920 patients aged 45 years and older who had visited the emergency room from 2009 to 2015 because of suicide attempts. They were divided into 3 groups according to age. Information about the suicide attempt and sociodemographic status was gathered through interviews with attempters or caregivers. Chi-square test and logistic regression analysis were performed to evaluate the differences among the 3 groups. We found that old-old suicide attempters had high intent to die and high medical lethality as a result of the attempt, and illness-related problems exerted a strong motivational effect on this group. Psychiatric drugs, pesticides, and herbicides were frequently used to attempt suicide. These attempts were less likely to be associated with alco...

The aim of this study is to investigate whether delirium patients with psychotic symptoms (PS) would have unique clinical characteristics and outcomes. A retrospective chart review was performed on the patients with delirium due to general medical conditions to assess clinical characteristics and outcomes. All patients were assessed by Delirium Rating Scale-revised-98 and classified as having PS when scored two or more on at least one of the psychotic symptom items (perceptual disturbances, delusions, and thought process abnormalities). Of 233 patients with delirium, 116 (49.8%) manifested PS. Patients with PS were younger, more likely to use antipsychotics to manage delirium, and had more hyperactive motor subtype than patients without PS. Logistic regression analysis showed that odds ratio of psychotic symptoms for having...
