“…In a previous study from China, a history of alcohol use disorder was only significantly associated with an increased risk for suicide in male, rural residents, and those with age < 40 years old [32] . In our study, all suicide victims were rural residents and were matched with age and gender, therefore, alcohol use disorder might lose its discriminative effect on the risk of suicide in our study The finding of lower education level as a trended risk for suicide (Table 3) is consistent with the case-control studies in young rural Chinese [6] and in general Chinese population [4] , and other population-based studies from different countries [7,10,[12][13]94] . However, among the psychiatric patients, a higher level of education (postgraduate education) was associated with increased risk for suicide compared to those with lower education [95] .…”

Objective: Suicide is a major public health problem in China, particularly in rural areas. This study aimed to examine the rate and the risk factors for suicide in a rural area of China. Methods: The mortality data of two counties in Shandong Province from January 1st, 2004 to December 31st 2005 were used. Death information was collected via face-to-face interview with informant(s). Psychological autopsy was conducted on 137 completed suicides and 137 matched controls died from other illnesses. Chisquare/Fisher exact and multiple logistic regression were used for bivariate analyses and predictor analyses, respectively. Results: The suicide rate was 20.90 per 100,000 persons per year with almost equal rates of males and females. Among those with the age over 40 years old, the suicide rate in males was significantly higher than that in females. The peak of suicide fell in the age group of 70-79 years for males and the age group of ≥ 80 years for females. The most commonly used method for suicide was pesticide ingestion (76.7%). Poor interpersonal relationship (OR=12.79), childhood adversities (OR=7.26), a history of mental illness (OR=5.95), adverse life event(s) within 1 year prior to death (OR=3.19), and unstable extravert personality traits (OR=6.12) were independent risk factors for suicide. Male gender positively interacted with majority of these risk factors, especially with a history of mental illness (OR=17.89). Advanced age positively interacted with all independent risk factors, with a history of mental illness having the largest OR of 1.51 as every 10 year of age advancement. In bivariate analyses, a history of previous suicide attempt (OR=13.06), a family history of suicide (OR=7.08), and unstable introvert personality trait (OR=1.83) were also associated with increased risk for suicide; and stable extravert personality trait (OR=0.21) was associated with decreased risk for suicide. Conclusions: In this rural population of mainland China, the risk for suicide was almost equal in both males and females with the elderly having the highest risk. The positive interactions of advanced age and male gender with independent risk factors suggest that suicide prevention strategies targeting specific groups with different risk factors are essential.

Purpose: This study was conducted to investigate factors influencing suicidal ideation in people with mental disorder. Methods: The subjects were 176 people with mental disorder from community mental health centers, social rehabilitation facilities, and university hospital psychiatric outpatient departments. The instruments used included a suicidal ideation questionnaire, a self-esteem scale, a spiritual well-being scale, a family support scale, and a professional support scale. Data were analyzed with t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis. Results: Suicidal ideation was influenced by age, history of suicidal attempts, and existential spiritual well-being. This study shows that suicidal ideation has negative correlation with existential spiritual well-being, self-esteem, family support, and age. Existential spiritual well-being, history of suicidal attempts, and age accounted for 30% regarding suicidal ideation in people with mental disorder. Conclusion: The lower existential spiritual well-being and age, the higher suicidal ideation. And also suicidal ideation was higher in people who had attempted suicide than in those who had not. Based on the outcomes of this study, it is necessary to design an intervention program that emphasizes existential spiritual well-being in order to decrease suicidal ideation in young people with mental disorder.

“…As mentioned previously, rates of suicide are especially elevated among young adults in South Korea, particularly females [2][3][4] ; thus, there is strong rationale to elucidate pathways to risk in this population. Additionally, thwarted belongingness may in fact be an important factor to consider in clarifying the association between insomnia and suicide in a collectivistic culture such as South Korea, compared to other individualistic cultures, such as the United States.…”

“…1 Rates of suicide and suicide attempts appear to be especially elevated in South Korea, particularly among young adult females. 2 Alarmingly, South Korea, which has been consistently ranked among countries with the highest suicide rates, 3 has also experienced a twofold increase in deaths by suicide over the past two decades. 4 To inform suicide prevention efforts both among high-risk South Korean young adults and high-risk individuals globally, research is needed not only to identify risk factors for suicide, but also to understand how these risk factors may be mechanistically and theoretically linked to suicide ideation, attempts, and fatalities.…”

Study Objectives: Suicide is a serious public health problem, and suicide rates are particularly high in South Korea. Insomnia has been identified as a risk factor for suicidal ideation; however, little is known about the mechanisms accounting for this relationship in this population. Based on the premise that insomnia can be lonely (e.g., being awake when everyone else is asleep), the purpose of this study was to examine whether greater insomnia severity would be associated with higher levels of thwarted belongingness and suicidal ideation, and whether thwarted belongingness would mediate the relationship between insomnia and suicidal ideation. Methods: Predictions were tested in a sample of 552 South Korean young adults who completed self-report measures of insomnia severity, suicidal ideation, and thwarted belongingness. Results: Greater insomnia symptom severity was significantly and positively associated with thwarted belongingness and suicidal ideation. Mediation analyses revealed that thwarted belongingness significantly accounted for the relationship between insomnia severity and suicidal ideation. Conclusions: These findings highlight the potential importance of monitoring and therapeutically impacting insomnia and thwarted belongingness to help reduce suicide risk.
