ABSTRACT
Objective@#This study aimed to examine how marital status, occupational status, and individual personality influence suicidal ideation and suicide attempts among Korean middle-aged adults, and explore the effects of their interaction. @*Methods@#A total of 2,464 middle-aged adults were surveyed about suicidality in the past year (1-year suicidality). Participants’ current marital and occupational status, including other demographic and clinical variables were investigated. Personality traits were assessed using the Big Five Inventory. The dependent variable was the presence of 1-year suicidality. Independent variables were current marital and occupational status. Generalized linear model (GLM) analysis was performed to adjust for other covariates. @*Results@#The group with 1-year suicidality had significantly lower income. It had a lower proportion of full-time employment, and higher percentages of part-time employment and unemployment. The GLM analysis results showed that marital and occupational status had no significant association with 1-year suicidality. Neuroticism and openness were positively associated with 1-year suicidality, whereas conscientiousness and extraversion had a negative association. Interactions between marital status and neuroticism, conscientiousness, and occupational status were significant. @*Conclusion@#Individualized social and psychological interventions for suicide prevention are required according to individual personality traits.
ABSTRACT
BACKGROUND: There has been no study on the time trends of dementia incidence in Korea. We report the 5-year incidence and its correlates of all-cause and Alzheimer's disease (AD) dementia, and compared our results with those of a 12-year-prior cohort study conducted in the same area. METHODS: A total of 751 community-dwelling older adults were followed up for a mean duration of 5.4 years. The age-, gender-, and educational attainment-specific incidence of all-cause and AD dementia were reported as cases per 1,000 person-years. We performed univariate and multivariate cox proportional hazard regression analyses to determine whether baseline sociodemographic, lifestyle, and clinical variables were associated with the risk of all-cause and AD dementia. A 12-year-prior cohort study was used for descriptive comparison to indicate the time trends of dementia incidence. RESULTS: The incidence rates were 16.2 and 13.0 cases per 1,000 person-years for all-cause and AD dementia, respectively. The baseline diagnosis of mild cognitive impairment increased the 5-year incidence of all-cause dementia by more than 4-fold. Old age and low baseline global cognitive function were noted as risk factors for both all-cause and AD dementia. CONCLUSION: Upon comparing the results with those from the earlier cohort study in Yeoncheon, the incidence of all-cause and AD dementia decreased by approximately 40% over 12 years; it has been mainly driven by the increase in the educational level of older adults. The declining time trends of incidence should be taken into account for estimating the future prevalence of dementia in Korea.

OBJECTIVES: The high suicide rate has risen as a main concern in South Korea. Given the complexity of the mechanism resulting in complete suicide, studies targeting various populations are needed for broader understanding of its risk factors. This study aims to analyze the factors affecting the suicidal tendency in the population of the elderly living alone in Seoul depending on basic elderly-care services. METHODS: A total number of 415 people participated in the study. Home-visit interviews were administered by trained interviewers. Suicidal tendency was measured by the Korean version of mini international neuropsychiatric interview (K-MINI). Health-related quality of life was measured by a brief version of the World Health Organization Quality-of-life Scale (WHOQOL-BREF). Alcohol problem was assessed by the Korean version of the alcohol use disorders identification test (AUDIT-K). Among total subjects of 415 interviewees, the actual responses of 408 people were used for the final analysis. RESULTS: The result showed that the suicide risk was high in persons isolated from social support [odds ratio (OR) = 4.49], having depression (OR = 14.85), and having low quality of life (OR = 4.39). CONCLUSIONS: We found that social support, depression and health-related quality of life are associated with suicidal tendency in the elderly living alone on basic services. Our evidence will contribute to suicide prevention policy for the elderly living alone on care services.

OBJECTIVE: The purpose of the present study was to investigate the association between Body Mass Index, suicide, perceived stress, and life dissatisfaction in a general population sample of Korean adults. METHODS: A total of 6,022 nationally representative adults aged 18 to 74 were selected using a multistage cross-sectional cluster sampling method. Questionnaires regarding suicide behaviors, perceived stress, and life satisfaction were completed by the participants. They also reported their heights and weights, which were used to calculate BMI. Psychiatric disorders were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, using the Korean version of the Composite International Diagnostic Interview. RESULTS: The results showed that being underweight was associated with higher risk for suicide ideation [odds ratio (OR), 1.6; 95% confidence interval (Cl), 1.18–2.05] and suicide attempt (OR, 2.0, 95% Cl, 1.23–3.31). Likewise, obesity also increased the risk of suicide ideation (OR, 1.3; 95% Cl, 1.11–1.56) although not suicide attempt. Furthermore, underweight individuals were more likely to report severe level of perceived stress (OR, 1.7; 95% Cl, 1.26–2.17) and life dissatisfaction (OR, 1.3; 95% Cl, 1.07–1.68). All of the results remained significant after adjusting for age, gender, education, and psychiatric illnesses. CONCLUSION: This study found that being underweight is a significant risk factor for suicide and poor subjective wellbeing in Korea. It suggests that BMI status may be an important modifiable factor for improving mental health in Korea.

OBJECTIVE: Education is expected to have an effect on differential item functioning (DIF) on the 15-item Modified Boston Naming Test in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (BNT-KC). However, no study has examined DIF in the BNT-KC. METHODS: We used the item response theory to investigate the impact of education on the DIF in the BNT-KC among elderly individuals with or without dementia (n=720). A two-parameter item response model was used to determine the difficulty and discrimination parameters of each item. The Benjamini-Hochberg procedure was used to address the risk of Type I errors on multiple testing. RESULTS: Four items, “mermaid,”“acorn,”“compass,” and “pomegranate” continued to demonstrate DIF after controlling for multiple comparisons. Those with low education levels were more likely to error on “mermaid” and “compass,” while those with high education levels were more likely to error on “acorn” and “pomegranate.”“Hand” and “red pepper” were too easily identified to be used for detecting dementia patients. “Monk's hat” and “pomegranate” were less discriminating than other items, limiting their usefulness in clinical setting. CONCLUSION: These findings may provide useful information for the development of a revised version of the BNT-KC to help clinicians make diagnostic decisions more accurately.

OBJECTIVE: We examined a functional model of acquired capability for suicide, which was elaborated from the “Interpersonal-Psychological Theory of Suicide”. METHODS: A total of 6,027 Korean community subjects were recruited from The Korean Epidemiologic Catchment Area study conducted in 2011. The subjects were assessed systematically using the Korean version of the Composite International Diagnostic Interview version 2.1, the Korean version of the Barratt Impulsiveness Scale, and the Korean version of the Mood Disorder Questionnaire. We used structural equation modeling to identify potential factors contributing to a suicide attempt. RESULTS: Most aspects of the model were supported by the data and “the short-term enhancer for the acquired capability for suicide” had direct effects on suicide attempts. However, the suicidal planning effects of “the short-term enhancer for the acquired capability for suicide” were eliminated by the rule of parsimony. CONCLUSION: The main finding was that “the short-term enhancer for the acquired capability for suicide” is relevant to suicide attempts when it's direct, indirect, and reciprocal effects are tested within a more complete system of relationships than found in existing studies. The implications of these findings are discussed with regard to future conceptual work and empirical research.

OBJECTIVE: There are conflicting reports about whether individual anxiety disorders are independently associated with suicidal ideation and suicide attempts. We examined whether anxiety disorders are related to suicidal ideation and suicide attempts in a community sample of South Korean adults. METHODS: In-person interviews based on the South Korean version of the Composite International Diagnostic Interview were conducted to diagnose mental disorders. Multivariate logistic regression analysis was performed to examine whether anxiety disorders were associated with suicidal ideation and suicide attempts. Each regression model treated lifetime diagnosis of anxiety disorders as independent variables. Sociodemographic characteristics, cohabitation status, lifetime history of mood disorders, alcohol use disorders, and psychotic disorders were included as covariates. RESULTS: Nationally representative sample of 6,510 South Korean adults aged 18–64 years was recruited. Multivariate analysis adjusted for psychiatric comorbidity and sociodemographic variables revealed that generalized anxiety disorder (GAD) [2.34, 95% confidence interval (CI) (1.27, 4.33)], post-traumatic stress disorder (PTSD) (3.50, 95% CI: 2.16, 5.68), specific phobia (1.55, 95% CI: 1.14, 2.11), social phobia (2.97, 95% CI: 1.27, 6.94), and obsessive-compulsive disorder (OCD) (5.58, 95% CI: 2.70, 11.6) were associated with suicidal ideation, whereas only social phobia (3.78, 95% CI: 1.41, 10.1) and PTSD (5.13, 95% CI: 2.81, 9.37) were associated with suicide attempts. CONCLUSION: Individual anxiety disorders are independently associated with suicidal ideation and/or suicide attempts. The importance of the early detection of anxiety disorders and of assessing the suicide risk in individuals with anxiety disorders is emphasized.

OBJECTIVES: The aim of this study is to evaluate difference of somatic symptoms of anxiety disorder and major depressive disorder and domainal association with suicidal idealization, plan, and attempts. METHODS: A total of 359 adults diagnosed with major depressive disorder and anxiety disorder of last one year participated. Participants interviewed with certain sections of Korean version of Composite International Diagnostic interview of CIDI. Sections of interests includes questionnaires regarding somatic symptoms and suicidal idea, plan and attempts of last one year. RESULTS: Chest pain shows more prevalence in major depressive disorder. Symptoms of Headache and loose stool are more prevalent in anxiety disorder. Difficulty in equilibrium and fainting spells are more common somatic complaints of co-diagnosis states of anxiety disorder and major depressive disorder. Comparing 3 domains of pain symptoms, gastrointestinal symptoms and pseudo-neurological symptoms, pain symptom domains, gastrointestinal symptoms domain shows significant statistic difference between diagnosis. Average somatic symptom numbers of each symptom domains increase through suicidal idealization, plan and attempt, accordingly. CONCLUSIONS: Our finding shows some of somatic symptoms are more prevalent at certain diagnosis. Since increasing numbers of somatic complaints of each symptom domains goes with the suicidal idealization to suicidal attempts, proper psychiatric evaluation and consultations are crucial for patients with numerous somatic complaints in non-psychiatric clinical settings.

Many epidemiological studies suggest that overweight is associated with an elevated risk of psychiatric disorders and suicidal tendency. However, findings vary across studies, and some have contradictory results. We investigated the relationship of overweight with a range of psychiatric disorders and suicidality in the Korean general population. A multistage cluster sampling design was adopted. A total of 6,022 participants aged 18–74 years completed face-to-face interviews (response rate: 78.7%) including assessment of psychiatric disorders, suicidality, and height and weight. Overweight (defined as body mass index of ≥ 25) was associated with an increase in the lifetime prevalence of depressive disorders (adjusted odds ratio [AOR] 1.38; 95% confidence interval [CI], 1.07–1.77), suicidal ideation (AOR, 1.42; 95% CI, 1.20–1.68), and suicidal plans (AOR, 1.44; 95% CI, 1.02–2.03), controlling for sociodemographic variables. Subgroup analysis found that the association between overweight and depressive disorders exists only in women aged 18–44 years (AOR, 1.75; 95% CI, 1.07–2.89) while the association of overweight with suicidal ideation (AOR, 2.08; 95% CI, 1.53–2.82) and suicide plans (AOR, 2.59; 95% CI, 1.25–5.37) existed only in men aged 18–44 years. Overweight was associated with increased odds of nicotine use disorders in women aged 18–44 years (AOR, 2.35; 95% CI, 1.02–5.43), but the association was in the opposite direction in men aged 45–74 years (AOR, 0.64; 95% CI, 0.43–0.94). In conclusion, overweight is related to various psychiatric disorders and suicidality in Korea. Policy makers and clinicians should pay more attention to the mental health of overweight individuals.

OBJECTIVE: The aims of this study were to estimate the prevalence of mental-physical comorbidity and health-threatening risk factors in subjects with mental disorders, and the risks of mental disorders in those with physical diseases for the last 12 months in the general Korean population. METHODS: Korean Epidemiologic Catchment Area study replication (KECA-R) was conducted for 6,510 adults between August 2006 and April 2007. The Korean version of Composite International Diagnostic Interview 2.1 (K-CIDI) was used in the survey. Prevalence of mental and physical disorders, and risk factors for physical health were calculated, and their associations were evaluated with adjustment for age and sex. RESULTS: Subjects with any mental disorder showed significantly higher prevalence of chronic physical conditions (adjusted odds ratio, AOR=1.5 to 2.8, p<0.001) and medical risk factors including smoking, heavy drinking, overweight, and hypertension (AOR=1.5 to 4.0, p<0.001). Of those with chronic physical conditions, 21.6% had one or more comorbid mental disorder compared with 10.5% of the subjects without chronic physical disorders (AOR=2.6, p<0.001). Contrary to expectations, depressive disorders did not show significant association with hypertension and prevalence of obesity was not influenced by presence of mental disorders. Further studies should assess these findings. CONCLUSION: This is the first identification of significant mental-physical comorbidity in the general Korean population. Clinicians and health care officials should keep in mind of its potential adverse effects on treatment outcome and aggravated disease-related socioeconomic burden.

OBJECTIVE: We examined whether childhood exposure to psychological trauma is associated with greater suicidality and whether specific psychiatric disorders modulate this association in a representative sample of Korean adults. METHODS: The Korean version of the Composite International Diagnostic Interview 2.1 was administered to 6,027 subjects aged 18-74 years. Subjects who experienced a traumatic event before the age of 18 years, the childhood-trauma-exposure group, were compared with controls without childhood trauma exposure. RESULTS: Childhood exposure to psychological trauma was associated with lifetime suicidal ideation (OR=3.19, 95% CI=2.42-4.20), suicide plans (OR=4.15, 95% CI=2.68-6.43), and suicide attempts (OR=4.52, 95% CI=2.97-6.88). These associations weakened after further adjustment for any psychiatric disorders, but they were not eliminated. The risk of suicide attempts related to childhood trauma increased with the presence of a concurrent alcohol use, depressive, or eating disorder. CONCLUSION: In terms of clinical implications, patients with these disorders who have a history of childhood trauma should be carefully assessed for their suicide risk and aggressively treated for psychiatric disorders.

OBJECTIVE: The aim of this study was to estimate the prevalence and correlates of mental disorders in Korean adults. METHODS: Door to door household surveys were conducted with community residents aged 18-74 years from July 19, 2011, to November 16, 2011 (n=6,022, response rate 78.7%). The sample was drawn from 12 catchment areas using a multistage cluster method. Each subject was assessed using the Korean version of the World Health Organization Composite International Diagnostic Interview (CIDI) based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). RESULTS: Lifetime and 12-month prevalence estimates were as follows: alcohol use disorders, 13.4% and 4.4%, respectively; nicotine use disorders, 7.2% and 4.0%, respectively; anxiety disorders, 8.7% and 6.8%, respectively; and mood disorders, 7.5% and 3.6%, respectively. The prevalence rates of all types of DSM-IV mental disorders were 27.6% and 16.0%, respectively. Being female; young; divorced, separated, or widowed; and in a low-income group were associated with mood and anxiety disorders after adjustment for various demographic variables, whereas being male and young were associated with alcohol use disorders. Higher income was not correlated with alcohol use disorder as it had been in the 2001 survey. CONCLUSION: The rate of depressive disorders has increased since 2001 (the first national survey), whereas that of anxiety disorders has been relatively stable. The prevalence of nicotine and alcohol use disorders has decreased, and the male-to-female ratio of those with this diagnosis has also decreased.

OBJECTIVES: The aim of the study was to develop a North Korean version of the Composite International Diagnostic Interview (NK-CIDI) and to evaluate the reliability and validity of NK-CIDI. METHODS: Subjects were 100 North Korean defectors, aged 18 to 65, who were recruited in a center for defectors in the National Medical Center or who were on an education curriculum in the defector settlement support center. NK-CIDI was developed based on the Korean version of CIDI considering the sociocultural background of North Korea. Inter-rater reliability, test/retest reliability, and validity of NK-CIDI were evaluated and kappa value was calculated. RESULTS: Different vocabularies and awkward expressions were adjusted, and additional explanations were supplemented for difficult phases. The target for development of NK-CIDI was early defectors who entered South Korea less than 3 months ago. Inter-rater reliability (n=30, kappa value 0.35-1.00), test/retest reliability (n=30, kappa value 0-0.86), and diagnostic validity (n=100, kappa value -0.02-0.42) were evaluated. CONCLUSION: Compared to the general population, defectors experience more psychiatric issues, and a standardized tool for diagnosis is needed. In this study, NK-CIDI was developed and the results suggest that reliability is acceptable but validity needs further verification. NK-CIDI could be utilized in future epidemiologic studies.

OBJECTIVE: The lifetime prevalence of alcohol dependence in South Korea remains higher than other countries. The aim of our study is to identify factors associated with remission from alcohol dependence. METHODS: Data from the Korean Epidemiological Catchment Area-Replication (KECA-R) study were used in our study. The Korean version of the Composite International Diagnostic Interview 2.1 (K-CIDI 2.1) was administered. Remission was defined as having no symptom of alcohol dependence for 12 months or longer at the time of the interview. Demographic and clinical variables putatively associated with remission from alcohol dependence were examined by t-test, chi-square-test and logistic regression analysis. RESULTS: The lifetime prevalence rate of alcohol dependence was 7.0%. Among them, 3.2% of the subjects were diagnosed with active alcohol dependence in the previous 12 months, and 3.8% were found to be in remission. Subjects in 35- to 44-year-old group, not living with partner group, and lower level of educational attainment group were more likely to be in the active alcohol dependence state. Of the comorbid mental disorders, dysthymia, anxiety disorder, nicotine use, and nicotine dependence were more common among the actively alcohol-dependent subjects. CONCLUSION: There is considerable level of recovery from alcohol dependence. Attention to factors associated with remission from alcohol dependence may be important in designing more effective treatment and prevention programs in this high-risk population.

While decreasing trend in gender differences in alcohol use disorders was reported in Western countries, the change in Asian countries is unknown. This study aims to explore the shifts in gender difference in alcohol abuse (AA) and dependence (AD) in Korea. We compared the data from two nation-wide community surveys to evaluate gender differences in lifetime AA and AD by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). Face-to-face interviews using the Composite International Diagnostic Interview (CIDI) were applied to all subjects in 2001 (n=6,220) and 2011 (n=6,022). Male-to-female ratio of odds was decreased from 6.41 (95% CI, 4.81-8.54) to 4.37 (95% CI, 3.35-5.71) for AA and from 3.75 (95% CI, 2.96-4.75) to 2.40 (95% CI, 1.80-3.19) for AD. Among those aged 18-29, gender gap even became statistically insignificant for AA (OR, 1.59; 95% CI, 0.97-2.63) and AD (OR, 1.18; 95% CI, 0.80-2.41) in 2011. Men generally showed decreased odds for AD (0.55; 95% CI, 0.45-0.67) and women aged 30-39 showed increased odds for AA (2.13; 95% CI 1.18-3.84) in 2011 compared to 2001. Decreased AD in men and increased AA in women seem to contribute to the decrease of gender gap. Increased risk for AA in young women suggests needs for interventions.

This study investigated gender differences in symptom profiles of major depressive disorder (MDD) in the Korean general population. Data were pooled from the series of nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001, 2006 and 2011, respectively. Of the 18,807 participants, 507 (397 women and 110 men) were diagnosed with MDD within the prior 12 months. In agreement with previous studies, women with MDD appeared to be more vulnerable to experiencing atypical depressive episodes defined as depression with two or more symptoms of fatigue, increased appetite and hypersomnia (P < 0.001). In terms of individual symptoms, female gender was significantly related with higher prevalence of fatigue (P = 0.008), hypersomnia (P = 0.001), noticeable psychomotor retardation (P = 0.029) and suicidal attempts (P = 0.016) with adjustment for birth cohort effect, partner status, and employment status. In the same analysis, men with MDD appeared more vulnerable to decreased libido than women (P = 0.009). This is the first report to demonstrate gender differences in symptomatology of MDD in the general Korean population, and the results are comparable to previous investigations from western societies. Assumingly, the intercultural similarity in female preponderance to atypical depression might reflect the common biological construct underlying the gender difference in mechanism of MDD. In clinical settings, gender differences of MDD should be carefully considered, because these features could be related with treatment response and drug side effects.

OBJECTIVES: This study was conducted to observe a longitudinal course of patients with schizophrenia enrolled in a community mental health center (CMHC) in Seoul, Korea, and to evaluate the clinical efficacy of case management provided for them. METHODS: Study subjects, including 50 patients in a case-managed group, and 34 patients in the control group, were enrolled from a CMHC and followed up for 36 months. Annual length of hospitalization was compared between two groups by t-tests and time until hospitalization by Kaplan-Meier survival analysis. RESULTS: For the first year of observation, there was no significant difference in annual length of hospitalization between two groups (3.4 weeks vs. 2.9 weeks), but annual length of hospitalization of the case-managed group became significantly shorter for the second (1.7 weeks vs. 7.2 weeks) and third year (1.4 weeks vs. 7.8 weeks). In Kaplan-Meier survival analysis, no difference in time until hospitalization was observed between two groups, but time until hospitalization more than 3 months was significantly shorter in the control group. CONCLUSION: At least two years of case management was required to reduce the length of hospitalization. Reduction in length of hospitalization was achieved by preventing long-term hospitalization.

OBJECTIVES: The purpose of this study was to investigate the differences of the suicidal behavior, stress, internet gaming disorder-related symptoms and personality profiles between online game overusers and general users. METHODS: A total of 460 adult online game users (40 overusers, 420 general users) participated in this study and were asked to complete several self-report measures. Questionnaires included demographic information, suicidal behavior, stress, internet gaming disorder-related symptoms, and big five inventory-10. RESULTS: Compared to the general user group, the overuser group showed statistically significant higher suicide idea, suicidal plan, stress, internet game withdrawal symptoms, online game-related daily life problems and lower extraversion, conscientiousness. Online game overusers showed lower extraversion, decreased conscientiousness, and higher neuroticism compared to the psychiatrically undiagnosed group. CONCLUSION: The current results indicate the possibility that online game overuse may be related to suicidal behavior, stress, and the personality traits of extraversion, conscientiousness, and neuroticism.

OBJECTIVE: We aimed to investigate the factors associated with suicidality among the elderly, focusing pain as the potential correlate. METHODS: This study was a community-based, cross-sectional study that included 413 elderly subjects aged 60 years and over with depression. Suicidality and pain were evaluated using Suicidal Ideation Scale and Geriatric Pain Measure, respectively. Participants were classified into two groups : 1) those with mild-to-moderate pain ; 2) those with severe pain. The risk of suicidality was determined using logistic regression, adjusting for age, sex, education, literacy status, marital status, living arrangement, the type of medical insurance, employment status, and the number of chronic medical illnesses. RESULTS: Among all subjects with depression, fifty-one (12.3%) presented clinically significant levels of suicidality. Those with severe pain were more likely to have suicidal idea (adjusted odds ratio : 20.49 ; 95% confidence interval : 8.15-51.51 ; p value : < 0.001) than those with mild-to-moderate pain, after adjusting for other variables. Other sociodemographic and clinical variables were not associated with the risk of suicide after adjustment. CONCLUSION: The severity of pain was strongly and independently associated with suicidality in the elderly individuals. This study suggests that the pain management should be emphasized to lower the rate of suicide in those experiencing depression in the late-adulthood.

OBJECTIVE: The 12-item General Health Questionnaire (GHQ-12) has been used extensively in various settings across different cultures. This study was conducted to determine the thresholds associated with optimum sensitivity and specificity for the GHQ-12 in Korean adults. METHODS: Data was acquired from a sample of 6,510 Korean adults, ages 18 to 64 years old, who were selected from the 2005 Census (2,581 men and 3,929 women). Participants completed the GHQ-12 and the Korean Composite International Diagnostic Interview (K-CIDI). Receiver Operating Characteristic (ROC) curve analysis was conducted. RESULTS: The mean GHQ-12 score for the total sample was 1.63 (SD 1.98). The internal consistency of the GHQ-12 was good (Cronbach's alpha=0.72). Results from the ROC curve indicated that the GHQ-12 yielded greater accuracy when identifying mood and anxiety disorders than when identifying all mental disorders as a whole. The optimal threshold of the GHQ-12 was either 1/2 or 2/3 point depending on the disorder, but was mainly 2/3. CONCLUSION: The Korean version of the GHQ-12 could be used to screen for individuals at high risk of mental disorders, namely mood and anxiety disorders.
