Objectives: To comprehensively examine the relationship between current sleep duration and past suicidal idea or attempt among Korean adolescents. Methods: Data came from the 2009 Korea Youth Risk Behavior Web-based Survey with 75 066 participants (with the participation rate of 97.6%) in 800 middle and high schools. Binary logistic regression was conducted by gender and depressed mood to identify significant factors for suicidal ideation/attempt. The dependent variable was the log odds of suicidal ideation/attempt, while the independent/control variables were sleep duration and other demographic, socio-economic and health-related factors. Results: A negative association between sleep duration and suicidal ideation or attempt was weaker for those with depressed mood than for those without such experience in Korea for Year 2009. The odds ratio of suicidal ideation/attempt regarding less than 4 hours of sleep compared to 6 to 7 hours of sleep, was smaller in a group with depressed mood than in a group without such experience, for example, 1.64 (95% confidence interval [CI], 1.29 to 2.08) vs. 2.06 (95% CI, 1.34 to 3.17) for men's suicidal ideation, 2.50 (95% CI, 1.69 to 3.69) vs. 3.89 (95% CI, 1.74 to 8.66) for men's suicidal attempt. A negative association between age (or self-rated health) and suicidal ideation/attempt was also weaker for those with depressed mood than for those without such experience in the nation for the year. Conclusions: There was a negative association between sleep duration and suicidal ideation/attempt in Korea for Year 2009 and this association was weaker for those with depressed mood than for those without such experience. Based on the findings of this study, adolescents' better mental health and longer, more comfortable sleep might help to prevent their suicidal ideation and attempt in Korea.

The purpose of this study was to identify the rate of suicidal attempts, investigate difference of rate of suicidal attempts between students and delinquents, and examine correlation between personality, family dynamics, environment, and suicidal attempts among Korean adolescents. Method: Data were collected through questionnaire surveys. Internal consistencies for this questionnaire ranged from 0.63 to 0.88. The subject used in this study consisted of 922(delinquent : 367, student : 555), using the proportional stratified random sampling method. Statistical methods employed were Chi-square and t-test. Results: \circled1 The rate of suicidal attempts were 10.8%, and the highest peak age of suicidal attempt was 17-18 year old (16.9%). \circled2 Delinquents(19.6%) showed a higher rate of suicidal attempts than students (5.1%). Among the students, girls (43.3%) showed a higher rate of suicidal attempt than boys (19.1%). Whereas, boys (80.9%) showed a higher rate of suicidal attempt than girls (56.7%) among delinquents. \circled3 Those who attempt suicide have more familial problem such as incest, psychosis, depression, attempted suicide, committed suicide, and alcoholism in their family. They also have more dysfunctional family dynamics, environment, and maladaptive personalities than non-attempters. Conclusions: Suicide and suicidal behaviors are multifaceted events. For suicide prevention, independent assessments of variables such as familial problems, personality, family dynamics, and environment must be considered.

Objective : The purpose of this study was to describe and compare trends in suicidal ideation, suicidal attempt and suicide in Republic of Korea from 2006 to 2011. Such data are needed to guide policies to reduce suicidal behaviors. Methods : Data came from the 2006-2010 Korea National Health and Nutrition Examination Survey, Korea National Statistical Office and 2006-2011 Korean Epidemiologic Catchment Area Study Replication and 2007-2011 National Emergency Department Information System. Results : No change occurred between 2006-2011 in suicidal ideation, suicidal attempt, whereas suicide rate increased annually. Suicidal attempt events was decreased in age over 50. Suicidal attempts by poisoning and hanging have increased, although suicide caused by poisoning of insecticide have decreased. Especially, suicides caused by hanging have gradually increased in both sex. Conclusions : These finding suggest that fatal suicidal methods may influence increased suicidal rate. Instead of traditional suicidal process, investigation of other pathway about suicidal behaviors should be needed.

Objective : Current study investigated the association between internet addiction and suicidal attempts in psychiatric patients. Methods : Patients who visited emergency department or psychiatry outpatient unit of Chungnam National University Hospital from January 2020 to July 2021 were included in this study. Total of 192 participants, 96 suicidal attempt cases and 96 psychiatric control patients without history of suicidal attempt were matched by gender and baseline diagnosis. Depression and internet addiction were assessed by using Patient Health Questionnaire-9 (PHQ-9) and Young's Internet Addiction Test (IAT). Independent t-tests, and logistic regression analyses were conducted. Results : IAT scores were significantly higher in suicidal attempt case group (41.09±18.196 years) compared to psychiatric control patients without history of suicidal attempt (36.63±17.016 years) (p=0.040). Internet addiction (adjusted Odds Ratio [aOR]=2.049, 95% Confidence Interval [CI]=1.004-4.539, p=0.0493) was an independent risk factor for suicidal attempt in psychiatric patients after controlling age, gender, and sociodemographic factors, such as marital status, education level and employment status. Conclusion : This is the first study to investigate the relationship between internet addiction and suicidal attempt in psychiatric patients in Korea. Internet addiction is significantly associated with suicidal attempt in psychiatric patients, after adjusting sociodemographic variables. This study provides evidence to future studies to further investigate on causality of internet addiction and suicidality in psychiatric patients.

Objective : Several studies hove suggested that reduction of cholesterol concentration and low cholesterol level increases suicide, homicide, and depression. The authors sought to determine whether low cholesterol is associated with a history of suicidal attempts among major depression patients. Method : The subjects were 105 patients with major depression, diagnosed according to the DSM-III-R criteria, and 105 age, sex matched healthy controls. Blood was token following overnight fast and serum cholesterol concentration were measured by a enzymatic method Results : The serum cholesterol level was significantly lower in the patients with major depression than in healthy controls($180.4{\pm}43.4mg/dl$ vs $199.7{\pm}35.8mg/dl$). And the serum cholesterol level was significantly lower in major depression patients with suicidal attempt than in major depression patients without suicidal attempt($156.7{\pm}38.2mg/dl$ vs $ 187.8{\pm}42.5mg/dl$) Conclusion : It is hypothesized that low cholesterol level is associated with depression by modifying the serotonin metabolism and the production of interleukin-2, low cholesterol concentration should be further investigated as a potential biological marker of suicidal risk in major depression. Prospective study with serial cholesterol determinations should be done.

Objectives The purpose of this study is to investigate the interest level, perception and attitude of suicide high-risk group toward the media's suicide report, and also to provide the fundamental data in order to strengthen both the standard and the recommendation of media coverage in Korea. Methods We analyzed the data from the 2013 The Korea National Suicide Survey. The study included 1500 participants aged between 19 and 75 years. The participants were selected through the regional multi-layer stratification method using the sampling frame of the 2010 Census. One-on-one face-to-face interviews investigated the interest level, opinions, and attitudes toward suicide reports and collected data on past suicide history and demographic data. The collected data were evaluated using multiple logistic regression analysis. A probability level of p < 0.05 was considered statistically significant. Results The suicide high risk groups with histories of suicidal ideations or attempts showed more interest in suicidal reports [suicidal thought odds ratio (OR) = 1.81, 95% confidence interval (CI) = 1.40-2.34 ; suicidal attempt OR = 3.21, 95% Cl = 1.52-6.78]. However, there was no difference among the groups in thought that suicide reports incite suicide (suicidal thought OR = 1.26, 95% Cl = 0.92-1.73 ; suicidal attempt OR = 0.96, 95% Cl = 0.44-2.09). The suicide high risk groups showed a positive attitude toward suicide reports, but it was not statistically significant (suicidal thought OR = 1.10, 95% Cl = 0.41-2.92 ; suicidal attempt OR = 1.10, 95% Cl = 0.76-1.59). Conclusions We suggest the need of careful attitude of media suicidal reports not to bring about copycat suicides. and also we offer suicide prevention campaign based on media leverage.
