Characteristics of young rural Chinese suicides: a psychological autopsy study

Pathways to suicide for children and youth in Guyana: A life charts analysis

BACKGROUND

Suicide is the third leading cause of death among youth aged 15 to 29 years old globally. Guyana has the highest rate of youth suicide in the world, yet only limited research exists.

AIM

The aim of this study is to identify key features of the suicide pathway for Guyanese children and youth and to distinguish meaningful subgroups.

METHOD

The psychological autopsy (PA) method was used to generate life charts for 15 Guyanese children and youth (10-29 years) who died by suicide. Nineteen close contacts of these individuals were interviewed about the life events of the decedent between 6 months and 5 years after their death. Semi-structured interviews lasting 30 to 150 min took place between November 2021 and January 2022. The interview data were converted into life charts and these were reviewed to uncover meaningful subgroups of suicide pathways.

RESULTS

Three groups with distinct suicide pathways were identified: hard life (46%), mental illness (20%) and interpersonal stress (20%). There were also two male youths for whom the suicidal antecedents and pathways were unclear. Interpersonal stress, alcohol, exposure to suicide and family history of suicide were common factors identified across groups.

CONCLUSIONS

The findings emphasise the role of both acute and protracted interpersonal stress for child and youth suicide in Guyana. The structure and dynamics of Indo-Guyanese families are discussed. Interventions recommended include enhancing child and youth community engagement, improving mental health and suicide literacy, alcohol restriction, increasing access to support services, and reducing stigma.

Interpersonal Relationship and Suicide Attempt: The Role of Family and Social Relationship

ABSTRACT

This study investigates the role of family and social relationships in cases of attempted suicide in China. Studies, mostly analyzing data from developed countries, have indicated that interpersonal relationships are important predictors of suicidal behaviors. This study's data were derived from a case-control study in China. Family relationships included relationships with spouses, parents, and parents-in-law. Poor family and social relationships were significantly associated with increased risk of attempted suicide in women and men. Depression and social support significantly mediated the association between interpersonal relationship and attempted suicide. Poor relationship with spouse was significantly associated with an elevated risk of attempted suicide. Relationship with parents-in-law was also significantly associated with attempted suicide in women, whereas family relationships played a more important role than social relationships in suicidal behaviors, especially in men. The findings imply that suicide prevention in China could be conducted from the perspective of improving family relationships, especially husband/wife and parents/daughters-in-law relationships.

Life Strain, Negative Emotions, and Religious Involvement in Contemporary China

Explaining religious growth in China remains a challenge for social scientists. Research on Western nations establishes religion as a powerful resource for coping with life strain. However, China's sociopolitical context, which often treats religion as deviant, is thought to function as a deterrent to conversion. When individuals experience life strain, they respond with negative emotions. Because those who experience strain may turn to non-traditional and deviant activities, we argue that they will be less deterred by China's negative framing of religion when seeking resources for coping. Applying lagged dependent variable models to the 2012-2014 China Family Panel Study, we find that life strain is associated with increases in religious affiliation, service attendance, and salience. Further analyses show that negative emotions mediate the effects of life strain on religiosity. Our study makes a substantial contribution to multiple bodies of literature by applying a theory of deviance to the study of religion, modernization, and mental health.

The Association Between Relative Deprivation, Depression, and Youth Suicide: Evidence From a Psychological Autopsy Study

OBJECTIVE

Suicide is a serious public health concern in China. In the present study, we investigated the specific mechanisms underlying relative deprivation and suicide in rural China.

METHODS

A large psychological autopsy study was conducted in rural China, in which 392 suicides and 416 community-living controls were consecutively recruited. Multiple logistic regression analysis was used to assess the relationship between relative deprivation and suicide, with depression as a potential mediator.

RESULTS

Young people who experienced relative deprivation were at a greater risk of suicide and depression. Depression plays a mediating role in the relationship between relative deprivation and suicide.

LIMITATIONS

Due to the limitations of the data, we cannot know whether there is mutual causation between relative deprivation and depression. The self-reported relative deprivation may also produce some influence on the results.

CONCLUSIONS

The current findings demonstrate the importance of relative deprivation as one of the four sources of psychological strain to explain how relative status is associated with suicide. The findings also can be translated into the clinical and preventive practice for suicide.

Prevalence of Suicidal Ideation, Suicide Plans, and Suicide Attempts Among Children and Adolescents Under 18 years of Age in Mainland China: A Systematic Review and Meta-Analysis

Despite suicide in younger population having become a severe public health issue, information on the prevalence of suicidality among Chinese children and adolescents is still limited. This study aims to estimate the prevalence of suicidal ideation, suicide plans, and suicide attempts in Chinese children and adolescents aged under 18 years. A meta-analysis was conducted based on English and Chinese publications from January 1, 2010 to December 31, 2020 using random-effects models. Based on 132 eligible studies with a combined total of 1,103,309 Chinese children and adolescents below 18 years old, the pooled prevalence of the overall suicidal ideation, suicide plans, and suicide attempts were 15.4% (95% CI [14.3, 16.6]), 6.4% (95% CI [5.5, 7.4]) and 3.5% (95% CI [3.1, 4.1]), respectively. The subgroup analyses showed that there were significant variations of prevalence of suicidal risks across genders, school stages, and geographical areas in mainland China. It was the first systematic review and meta-analysis to show suicidality among younger population aged below 18 years is prevalent in mainland China. This study suggests that gender-age-region-specific prevention and intervention programs should be urgently needed to reduce suicidal risks among Chinese children and adolescents.

Impulsivity in fatal suicide behaviour: A systematic review and meta-analysis of psychological autopsy studies

Our aim is to review and perform a meta-analysis on the role of impulsivity in fatal suicide behaviour. We included papers who used psychological autopsy methodology, assessed adult death by suicide, and included assessment of impulsivity. We excluded papers about assisted suicide, terrorist suicide, or other cause of death other than suicide or postmortem diagnosis made only from medical records or database. 97 articles were identified. 33 were included in the systematic review and nine in the meta-analysis. We found that people who die by suicide with high impulsivity are associated with younger age, substance abuse, and low intention to die, whereas those with low impulsivity were associated with older age, depression, schizophrenia, high intention to die and low social support. In the meta-analysis, suicide cases had higher impulsivity scores than living controls (Hedges' g = 0.59, 95 % CI [0.28, 0.89], p=.002). However, studies showed heterogeneity (Q = 90.86, p<.001, I2=89.0 %). Impulsivity-aggressiveness interaction was assessed through meta-regression (β=0.447, p=.045). Individuals with high impulsivity would be exposed to a higher risk of fatal suicide behaviour, aggressiveness would play a mediating role. People who die by suicide with high and low impulsivity display distinct characteristics, which may reflect different endophenotypes leading to suicide by different pathways.

Suicide warning signs that are challenging to recognize: a psychological autopsy study of Korean adolescents

BACKGROUND

In South Korea, the leading cause of youth death has been suicide for about 20 years. In this study, we conducted a multi-method psychological autopsy to identify the psychiatric diagnosis, developmental history, personality traits, family history, school life, warning signs of suicide, and risk factors related to suicide for the first time in Korea.

METHODS

This was a postmortem, retrospective, and descriptive study of 36 adolescents who died by suicide between August 2015 and July 2021 in South Korea. We obtained qualitative and quantitative data from the Korean Psychological Autopsy of Adolescent, conducted by the Suicide and School Mental Health Institute, the official student mental health policy-focused research institute of the Korean Ministry of Education.

RESULTS

The adolescents comprised equal percentage of girls and boys. Approximately half of the deaths (55.6%) occurred at home and most (72.2%) involved jumping from a height. Most of the adolescents (97.2%) had one major psychiatric disorder before death, with depressive disorder being the most prevalent (75%). They were at a high risk for internet addiction before death. The most common personality trait was avoidance (28.6%), followed by submissiveness (27.3%). Half of the parents reported that the adolescents were satisfied with their school life and the teachers observed that they had no behavioral problems. One year before death, seven (19.4%) adolescents injured themselves and five (13.9%) had attempted suicide. Most of the deceased (80.6%) had expressed suicide warning signs to their families within one year before death. Adolescents had a long experience of family-related adverse events.

CONCLUSIONS

Most of the adolescents had mental health disorders and expressed suicidal intentions using verbal and nonverbal signs. However, it was challenging for families to recognize the risk signs because of adolescents' personality traits or a good school life. To prevent adolescent suicide, adolescents, parents, and teachers need to be educated to recognize signs of suicide warning signs and equipped to guide adolescents to appropriate care.

Marital status and suicidal behavior in South Asia: A systematic review and meta-analysis

BACKGROUND AND AIMS

The connection between marital status and suicidal behavior has been poorly assessed in South Asia. We aimed to see the proportion of marital status in individuals with suicidal behavior in South Asian countries.

METHODS

We followed PRISMA guidelines and registered the protocol in advance (PROSPERO 2023 CRD42023399906). A systematic search was conducted in Medline, Embase, and PsycINFO. Meta-analyses were performed to pool the proportion of married individuals with suicidal behavior (total [suicide + suicide attempts], suicide, and suicide attempt) in South Asian countries. We considered suicidal behavior consist of suicide and suicide attempts (nonfatal).

RESULTS

Our search identified 47 studies for this review from 6 countries published from 1999 to 2022 with a sample size ranging from 27 to 89,178. The proportion of married individuals was 55.4% (95% CI: 50.1-60.5) for suicidal behavior, 52.7% (95% CI: 44.5-60.7) for suicides, and 43.1 (95% CI: 32.9-53.9) for suicide attempts. The proportion of married persons among suicide attempts varied significantly across countries (p = 0.016) which was highest (61.8%; 95% CI: 57.2-66.2) in India, followed by Bangladesh (52.5%; 95% CI: 41.8%-62.9%) and Pakistan (45.1%; 95% CI: 30.9-59.9). The pooled proportions did not differ significantly in relation to the quality of the studies (p = 0.633).

CONCLUSION

This review identified married persons died more than others by suicide in South Asian countries while single persons attempted suicide than married. As the current study did not assess any cause-and-effect association, a cautious interpretation is warranted while considering married marital status as a risk factor.

Impulsivity, suicidal thoughts, psychological distress, and religiosity in adolescents and young adults

Background

Impulsivity is associated with suicidal acts and ideation, whereas higher religious commitment has been identified as a potential protective factor linked to lower suicidal ideation.

Objectives

We examined the extent to which higher religious commitment is associated with lower suicidal ideation and whether religious commitment modifies the relationship between impulsivity and suicidal ideation.

Methods

Adolescent and young adult males, with a prior history of suicidal act and ideations, completed standardized questionnaires [i.e., Beck Scale for Suicidal Ideation (BSS), Barratt Impulsivity Scale-II (BIS-II), Depression Anxiety Stress Scale (DASS), and Religious Commitment Inventory-10 (RCI-10)], to assess impulsivity, suicidal ideation, distress, and religious commitment. Regression and mediation analyses were performed to investigate the relationships among impulsivity, religious commitment, and suicidal ideation.

Results

Of the 747 study participants (mean age 18.8 years, SD = 4.1), 151 (20.2%) had a history of suicidal acts and 177 (23.7%) had a history of suicidal ideation. Non-planning impulsivity (predictor) was inversely associated with religious commitment (r = -0.33, p < 0.01), and religious commitment (mediator) was inversely related to suicidal ideation (outcome) (r = -0.32, p < 0.01). These findings remained statistically significant when controlling for either religious commitment or non-planning impulsivity, as appropriate. Higher religious commitment reduced the association between non-planning impulsivity and suicidal ideation (p < 0.01).

Conclusion

The findings highlight the potential for cultivating spirituality to buffer against higher suicidal ideation, and thus could be considered as an additional therapeutic strategy for individuals with higher levels of impulsivity and co-morbid suicidal ideation.

Factors of suicidal behavior among inpatients with major depressive disorder: A retrospective case series

OBJECTIVE

Previous studies indicate that more than half of those who died by suicide had a depressive disorder. When discussing the factors associated to suicidal behavior (SB) among patients with major depressive disorder (MDD), sociocultural contexts should also be carefully considered. This case series study explored the factors correlated to SB among MDD patients in Beijing, China.

METHODS

The patient information sheets were retrieved from an electronic database that comprised patient medical information. Three forms of binary logistic regression equations were conducted to explore the factors associated to SB among patients with MDD. For the inconsistent variables produced by the three regression models, the propensity score matching (PSM) analysis was done for further verification.

RESULTS

In this retrospective study, 1,091 depressed cases were enrolled. The difference between the SB group and non-SB group in gender, impulsivity, the severity of depression, history of major mental trauma, and family history of suicide were statistically significant in univariate comparisons (P < 0.05); the binary logistic regression analysis and the PSM analysis showed that female gender, history of major mental trauma, impulsivity, family history of suicide and severity of depression were factors correlated to SB among patients with MDD (odds ratios >1).

CONCLUSIONS

Female gender, the history of major mental trauma, impulsivity, the severity of depression, and family history of suicide were independently associated with the appearance of SB among MDD patients in Beijing, China. Inevitably, these findings should be viewed with particular caution due to the inherent drawbacks of a retrospective nature. More prospective longitudinal research should be conducted to examine those dynamic alterations in the corresponding confounders.

Predictive factors for recurrent suicide attempts: Evidence from the ACTION-J study

Aim

Risk factors for attempted suicide have been widely studied. However, there is limited evidence on predictive factors for suicide reattempts. We aimed to identify these in suicide attempters admitted to emergency departments.

Methods

This is the second analysis from a randomized controlled multicenter trial, ACTION-J. Patient characteristics were extracted from baseline demographic data and clinical data of participants. Predictive factors for a recurrent suicide attempt in each gender were examined using Cox proportional hazards regression analysis. Dependent variables were months from trial entry to the first reattempt. Independent variables were characteristics regarded as potential predictive factors.

Results

The study included 914 adults (400 men and 514 women). A visit to a psychiatrist within a month of the suicide attempt was significantly associated with reattempts in men (hazard ratio [HR] 2.49, 95% confidence interval [CI] 1.21-5.25). Substance-related disorders (HR 3.65, 95% CI 1.16-7.9.60), drinking alcohol less than once per month (HR 0.42, 95% CI 0.17-0.88), previous suicide attempts (HR 2.28, 95% CI 1.40-3.87), and taking a drug overdose for the first suicide attempt (HR 1.82, 95% CI 1.14-3.01) were significantly associated with reattempts in women.

Conclusion

Our data highlight the importance of visits to a psychiatrist a short time before the first suicide attempt in men and substance-related disorder, previous suicide attempts, and drug overdose in the first suicide attempt in women as predictive factors for future suicide reattempts.

Risk Assessment on Suicide Death and Attempt among Chinese Rural Youths Aged 15-34 Years

Background: Although many suicide risk assessment tools are available in the world, their validity is not adequately assessed. In this study, we aimed to develop and evaluate a suicide risk assessment model among Chinese rural youths aged 15–34 years. Method: Subjects were 373 suicide deaths and 507 suicide attempters aged 15–34 years in three Chinese provinces (Shandong, Liaoning, and Hunan). Information about the community residents was also collected as the control groups. Social-demographic, social and psychological variables were examined for the suicides, suicide attempters, and community residents. Logistic regressions based on subjects from Shandong and Liaoning provinces were conducted to establish the suicide risk assessment models. Receiver operating characteristic (ROC) curves were drawn, and area under the ROC curves (AUC) were calculated to show how well the models separated the group being tested into those with and without suicide attempt or suicide. Results: The assessment model for suicide death included education years (OR = 0.773, p < 0.001), agricultural worker (OR = 2.091, p < 0.05), physical health (OR = 0.445, p < 0.05), family suicide history (OR = 6.858, p < 0.001), negative life events (OR = 1.340, p < 0.001), hopelessness (OR = 1.171, p < 0.001), impulsivity (OR = 1.151, p < 0.001), and mental disorder (OR = 8.384, p < 0.001). All these factors were also supported in the assessment model for suicide attempt, with an extension of very poor economic status (OR = 1.941, p < 0.01) and social interaction (OR = 0.855, p < 0.001). The AUC was 0.950 and 0.857 for the sample used to establish the assessment models of suicide death and attempt, respectively. The AUC was 0.967 and 0.942 for the sample used to verify the established assessment models of suicide death and attempt, respectively. Conclusions: Compared with some other assessment tools, the models for suicide death and attempt in the current study performed well among Chinese rural youths aged 15–34 years. A reliable suicide risk assessment approach, which includes multiple risk factors, should be evaluated in various cultures and populations.

Suicide means, timing, intent and behavior characteristics of the suicides with schizophrenia

BACKGROUND

Studies have been reported on suicide and schizophrenic suicide, but few compared certain characteristics of suicides with and without schizophrenia.

METHODS

A sample of 392 suicides was consecutively recruited from 16 counties in three provinces of China. Psychological autopsy method was applied to collect the information through informants. The questionnaire of characteristics for suicidal behavior, Beck's Suicide Intent Scale (SIS), and the DSM-IV based SCID were applied.

RESULTS

About 9.7% of the sampled suicides (n = 38) were diagnosed with schizophrenia, and they were more likely to be female and older in age. No significant differences were found on violent suicide means, but significant differences within non-violent means between two groups. Schizophrenic suicide was more likely to happen in the second quarter of the year (April - June), middle of the month (11th-20th), and in the afternoon (3:01 pm - 6:00 pm). The schizophrenic suicides had higher suicide intent than those without schizophrenia and were more inclined to be isolated, more likely to tell people their suicide intent, and less likely to prepare posthumous papers.

CONCLUSION

Schizophrenic suicides have unique characteristics, and targeted preventive measures should be taken to prevent schizophrenic suicides. To accurately identify characteristics of suicide behavior is meaningful to prevent schizophrenic suicides in clinical practice.

Contributing factors to suicide: Political, social, cultural and economic

This review summarizes recent research in four environmental areas affecting risk of deaths by suicide. Politically, the weight of the evidence suggests that laws increasing social welfare expenditures and other policies assisting persons with low incomes (e.g., minimum wage) tend to lower suicide rates. Other legal changes such as those restricting firearms and alcohol availability can also prevent suicides. The social institutions of marriage, as well as parenting, continue to serve as protective factors against suicide, although the degree of protection is often gendered. Religiousness tends to be inversely associated with suicide deaths at the individual level of analysis, but the mediators need exploration to determine what accounts for the association: social support, better mental health, better physical health, less divorce, or other covariates. Cultural definitions of the traditional male role (e.g., breadwinner culture) continue to help explain the high male to female suicide ratio. New work on the "culture of suicide" shows promise. The degree of approval of suicide is sometimes the single most important factor in predicting suicide. At the individual level of analysis, two of the strongest predictors of suicide are economic ones: unemployment and low socio-economic status. Attention is drawn to enhancing the minimum wage as a policy known to lower state suicide rates. Limitations of research include model mis-specification, conflicting results especially when ecological data are employed, and a need for more research exploring moderators of established patterns such as that between religiousness and suicide.

Relationship of religion with suicidal ideation, suicide plan, suicide attempt, and suicide death: a meta-analysis

BACKGROUND

Suicide is a significant public health problem and one of the leading causes of death worldwide. The effect of religion on suicidal behaviors (i.e., ideation, plan, attempt, and death) is an important issue worthy of consideration.

METHODS

Major electronic databases, including MEDLINE, Web of Science, and Scopus, were searched for the articles published until 26 April 2021. Reference lists were also screened. Observational studies addressing the associations between religion and suicidal behaviors were also examined. Between-study heterogeneity was investigated using the χ2, τ2, and I2 statistics. The probability of publication bias was explored using the Begg and Egger tests, as well as trim-and-fill analysis. The effect size was expressed as odds ratio (OR) with 95% confidence intervals (CIs) using a random-effects model.

RESULTS

Out of 11 389 identified studies, 63 articles were eligible, involving 8,053,697 participants. There was an inverse association between religion and suicidal ideation OR  =  0.83 (95% CI: 0.78, 0.88; P &lt; 0.001), suicidal plan OR  =  0.93 (95% CI: 0.83, 1.04; P =  0.200), suicide attempt OR  =  0.84 (95% CI: 0.79, 0.89; P &lt; 0.001), and completed suicide OR  =  0.31 (95% CI: 0.14, 0.72; P =  0.006). There was a no evidence of publication bias.

CONCLUSIONS

The results of this meta-analysis support the notion that religion can play a protective role against suicidal behaviors. Nonetheless, the effect of religion on suicidal behaviors varies across countries with different religions and cultures. Although this association does not necessarily imply causation, an awareness of the relationship between religion and suicide risk can be of great help in suicide prevention policies and programs.

Estimating the risk of suicide associated with mental disorders: A systematic review and meta-regression analysis

BACKGROUND

Mental disorders (MDs) are known risk factors for suicide. This systematic review updates the evidence base for this association and improves upon analytic approaches by incorporating study-level and methodological variables to account for measurement error in pooled suicide risk estimates.

METHODS

A systematic review was conducted to review studies on MDs as risk factors for suicide. Relevant studies were searched using PubMed, Embase, PsychINFO, and existing reviews from 2010 to 19. Studies were eligible if they were longitudinal/case-control studies, representative of the general population, used diagnostic instruments, and quantified suicide risk. The outcome assessed was relative risks (RRs) for suicide due to MDs. A multi-level meta-regression approach was used to obtain pooled RRs adjusted for covariates and between-study effects.

FINDINGS

We identified 20 eligible studies yielding 69 RRs. Disorder type, age, sex, use of psychological autopsy, study design, and adjustment for confounders were tested as predictors of pooled suicide risk. Overall, all disorders were significant predictors of suicide with predicted adjusted RRs ranging from 4·11 [2·09, 8·09] for dysthymia to 7·64 [4·3, 13·58] for major depressive disorder.

INTERPRETATION

Our results indicate that MDs are important risk factors for suicide. This systematic review provides pooled RRs that have been adjusted for methodological sources of bias. Findings from our paper may inform suicide prevention strategies as part of national health agendas.

Relationship and Effects of Community Problems on Anxiety and Suicide: A Case-Control Psychological Autopsy Study

This study aimed to explore the relationship and the effects of community problems on anxiety and suicide. Data were from a case-control psychological autopsy study (392 suicides and 416 community living controls) carried out in 16 rural counties from three provinces in China. The World Health Organization Suicide Prevention-Multisite Intervention Study on Suicidal behaviors scale of community stress and problems and Spielberger State-Trait Anxiety Inventory were used to measure the community problems and trait anxiety. Spearman's correlation and multivariable regression methods were used to probe the effect of community problems on anxiety and suicide. There were 12 and 6 community problems correlated with anxiety (rs = 0.169, p < 0.001) and suicide (rs = 0.081, p = 0.022), respectively. Medical care, alcohol abuse, superstition, and job security were important community problems for anxiety and suicide. Community problems had stronger correlation with anxiety than suicide. It might be an effective method to reduce anxiety and suicide risk by solving different community problems.

The pattern of stressful life events prior to suicide among the older adults in rural China: a national case-control psychological autopsy study

Background

There is a lack of evidence concerning the stressful life events experienced prior to suicide which may be associated with an increased suicide risk among Chinese rural older adults. The aim of this study was to identify the pattern of stressful life events prior to suicide among the older adults in China.

Methods

Twelve counties were randomly selected using two-stage stratified cluster sampling method. Suicide cases aged 60 years and older (n = 242) were collected from those counties from June 2014 to September 2015. Matched living controls were selected 1:1 with suicide cases by age, gender, and location. Data were collected using face-to-face interviews by a psychological autopsy method. The Life Event Scale for the Elderly was used to measure the stressful life events prior to suicide/interviews.

Results

Approximately 99.6% of suicide cases and 88.4% of controls experienced at least one stressful life event. The suicide group experienced more long-term stressful life events than recent stressful life events. The top three most frequent stressful life events for the suicide group were being diagnosed with chronic disease, hospitalization, and being diagnosed with terminal illness. More female suicide cases experienced the death of a spouse, while more males experienced hospitalization, diagnosis with terminal illness and family poverty. Experiencing at least one stressful life event, an unstable marital status, physical diseases and mental disorders were shown to increase the risk of suicide.

Conclusions

Stressful life events were common for the rural older adults, especially long-term stressful life events. The experience of at least one stressful life event can increase suicide risk among this population. More attention should be paid to the rural older adults who experienced more long-term stressful life events and health related life events.

Comparing Suicide Attempters With and Without Mental Disorders: A Study of Young Adults in Rural China

Over 90% of suicides in the West could be diagnosed with mental disorders, while only 50-70% of Chinese suicides had mental disorders. Using data from a case-control study on suicide attempt, we aimed to compare characteristics and risk factors between suicide attempters with and without mental disorders. Demographic and social psychological characteristics were compared between attempters with and without mental disorders. 19.1% of the suicide attempters were diagnosed with mental disorders. Suicide attempters with mental disorders endured more strain than those without. Strain was an independent risk factor for suicide attempt among people without mental disorders. Psychological strain might be an important reason for both mental disorders and following suicide attempt. More efforts on suicide prevention should be spent on people without mental disorders. The impact of social psychological factors, such as religion, negative life events, and psychological strains should be considered.

Association of Religious Activity with Male Suicide Deaths

OBJECTIVE

To analyze the relationship between suicide in men and stratified measures of religiosity.

METHODS

We studied 192 suicides and 81 controls (nonsuicide, sudden, or accidental death). We employed the psychological autopsy method to compile diagnoses based on DSM-IV criteria. Overall, religiosity and participation in religious associations were determined using a Likert-type scale. Given the limited participation of women in the religious associations of southern Spain, only male subjects were included.

RESULTS

Religious participants had decreased risk of suicide compared to nonparticipants (OR = 0.148, 95% CI = 0.049-0.447). This lower risk was further associated with the degree of involvement in religious activity. Suicides accounted for 73.47% of subjects with no religious participation, 61.17% of those with some participation, and 56.52% of frequent participants (linear trend test Z = -2.0329, p = .042). Membership in a religious association was also associated with a lower rate of suicide compared to nonmembers (OR = 0.356, 95% CI = 0.172-0.736). This effect was similarly associated with the degree of involvement in the association. Suicides accounted for 74.67% of subjects who never participated in the activities of a religious association, 69.23% of those who sometimes participated, and 42.86% of frequent participants (linear trend test Z = -3.4082, p < .001).

CONCLUSIONS

Religiosity, either as general participation or through a religious association, was associated with protection against suicide proportional to the degree of involvement in religious activities.

The association between psychological strain and suicidal behaviors among college students: A mental health survey in Jilin Province, Northeast China

BACKGROUND

Suicide is a major global mental health problem among college students. The aim of the current study was to explore the association between the psychological strains of the strain theory of suicide and suicidal behaviors among college students.

METHODS

Participants comprised 1912 college students (16-28 years old, 47.2% female) from three universities in Jilin Province, China, who completed the self-report assessments of psychological strains (40 items Psychological Strains Scale) and suicidal behaviors (Suicidal Behaviors Questionnaire-Revised). The demographic characteristics included four variables: health status, psychological status, academic status and economic status.

RESULTS

Approximately 15.0% (286/1912) of participants were classified as having suicide risk, based on the cut-off scores of the SBQ-R. The prevalence of suicidal behaviors among males and females was 11.9% (120/1009) and 18.4% (166/903), respectively. Value strain (OR = 1.075, 95%CI: 1.057-1.094), aspiration strain (OR = 1.082, 95%CI: 1.064-1.101), deprivation strain (OR = 1.073, 95%CI: 1.052-1.093), and coping strain (OR = 1.095, 95%CI: 1.075-1.116) were risk factors for suicidality in college students. Coping strain (OR = 1.050, 95%CI: 1.023-1.077) was still positively associated with suicide risk in multivariate logistic regression. Logistic regression analysis indicated that coping strain had the highest correlation with suicidal behaviors.

LIMITATIONS

The directionality of the relationships cannot be deduced because this study is cross-sectional.

CONCLUSION

This study confirms a strong association between psychological strains and suicidal behaviors in college students. Some measures can be taken to reduce psychological strains to mitigate suicide risk among college students. More studies investigating coping strain among college students are warranted.

Invited Commentary: Religion as a Social Determinant of Health

There is broad agreement that religion is a social determinant of health. In the article by Chen and VanderWeele (Am J Epidemiol. 2018;187(11):2355–2364), the authors took an outcome-wide approach to demonstrate associations between religious practices early in the life course (regular service attendance and prayer/mediation) and a wide range of health endpoints and behaviors later on. Is religion a panacea? The study adds to the evidence that religious practices are correlated with a broad swath of health outcomes. However, more work is needed to translate that evidence into practicable advice for individuals and for society. The following tasks remain. 1) We must sharpen our understanding of which elements of religious practices promote health. (Specifically, is it service attendance, prayer, or both? Could a nonreligious person achieve the same benefit via regular participation in a secular group, like a choir?). 2) We should improve our understanding of the different contexts in which religion is likely to have beneficial, as well as potentially harmful, effects.

Psychiatric morbidity and suicidal behaviour in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Psychiatric disorders are reported to be present in 80% to 90% of suicide deaths in high-income countries (HIC), but this association is less clear in low- and middle-income countries (LMIC). There has been no previous systematic review of this issue in LMIC. The current study aims to estimate the prevalence of psychiatric morbidity in individuals with suicidal behaviour in LMIC.

METHODS AND FINDINGS

PubMed, PsycINFO, and EMBASE searches were conducted to identify quantitative research papers (any language) between 1990 and 2018 from LMIC that reported on the prevalence of psychiatric morbidity in suicidal behaviour. We used meta-analytic techniques to generate pooled estimates for any psychiatric disorder and specific diagnosis based on International classification of disease (ICD-10) criteria. A total of 112 studies (154 papers) from 26 LMIC (India: 25%, China: 15%, and other LMIC: 60%) were identified, including 18 non-English articles. They included 30,030 individuals with nonfatal suicidal behaviour and 4,996 individuals who had died by suicide. Of the 15 studies (5 LMIC) that scored highly on our quality assessment, prevalence estimates for psychiatric disorders ranged between 30% and 80% in suicide deaths and between 3% and 86% in those who engaged in nonfatal suicidal behaviour. There was substantial heterogeneity between study estimates. Fifty-eight percent (95% CI 46%-71%) of those who died by suicide and 45% (95% CI 30%-61%) of those who engaged in nonfatal suicidal behaviour had a psychiatric disorder. The most prevalent disorder in both fatal and nonfatal suicidal behaviour was mood disorder (25% and 21%, respectively). Schizophrenia and related disorders were identified in 8% (4%-12%) of those who died by suicide and 7% (3%-11%) of those who engaged in nonfatal suicidal behaviour. In nonfatal suicidal behaviour, anxiety disorders, and substance misuse were identified in 19% (1%-36%) and 11% (7%-16%) of individuals, respectively. This systematic review was limited by the low number of high-quality studies and restricting our searches to databases that mainly indexed English language journals.

CONCLUSIONS

Our findings suggest a possible lower prevalence of psychiatric disorders in suicidal behaviour in LMIC. We found very few high-quality studies and high levels of heterogeneity in pooled estimates of psychiatric disorder, which could reflect differing study methods or real differences. There is a clear need for more robust evidence in order for LMIC to strike the right balance between community-based and mental health focussed interventions.

Community leaders' attitudes towards and perceptions of suicide and suicide prevention in Ghana

Community leaders can play an important role in suicide prevention because they are potential gatekeepers in resource-poor settings. To investigate their attitudes towards suicide and the role they play when people are in suicidal crisis, 10 community leaders were interviewed in a rural community in Ghana. Thematic Analysis of the interviews showed that leaders held two conflicting views about suicide: health crisis and moral taboo. They also viewed the reasons for suicide as psychosocial strains more than psychiatric factors. Though they viewed suicide as a moral taboo, they maintained a more neutral position in their gatekeeping role: providing support for persons in suicidal crisis more often than exerting a condemnatory attitude. Implications for gatekeeper training are discussed.

Prolonged Risk of Suicide Reattempts in Patients with Alcohol Use Disorder and Acute Alcohol Use: A Register-Based Follow-Up Study (2010-2015)

OBJECTIVE

This study aimed to clarify the role of acute alcohol use and alcohol use disorder in individuals exhibiting suicidal behaviors, including repetition of suicide attempt.

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.

The association of religiosity with suicidal ideation and suicide attempts in the United Kingdom

OBJECTIVE

The goal was to analyze the association of religiosity with suicidal ideation and suicide attempts in a UK nationally representative sample.

METHODS

This study used cross-sectional data from 7403 people who participated in the 2007 Adult Psychiatric Morbidity Survey (APMS). Religion was assessed with the question 'Do you have a specific religion?' with 'yes' and 'no' answer options. Lifetime and past 12-month suicidal ideation and suicide attempts were assessed. The association between religiosity and suicidality was studied in multivariable logistic regression models adjusted for sociodemographic, behavioural, and psychopathological factors.

RESULTS

Compared to those without a religion, the prevalence of past 12-month suicidal ideation (3.2% vs. 5.4%), past 12-month suicide attempts (0.4% vs. 0.9%), lifetime suicidal ideation (11.2% vs. 16.4%), and lifetime suicide attempts (3.6% vs. 6.0%) was lower among those with a religion. In the fully adjusted model, having a religion was significantly associated with lower odds for all types of suicidality except past 12-month suicide attempts: suicidal ideation (past 12-month: OR = 0.71, 95% CI = 0.51-0.99; lifetime: OR = 0.83, 95% CI = 0.69-0.99) and suicide attempts (past 12-month: OR = 0.71, 95% CI = 0.35-1.45; lifetime: OR = 0.69, 95% CI = 0.53-0.90).

CONCLUSION

There is a negative association between religiosity and suicidality in the UK. Future studies should focus on the underlying mechanisms.

Relationship between mortality in people with mental disorders and suicide mortality in China during 2000 to 2014: An observational study

Suicide is one of the top 10 causes of death in many countries. Although there are many studies on mental disorders, few studies have examined mortality in suicide population and mentally ill population. This study examined the association between mortality and mental disorders using data on suicides and mental disorders in China. Data from China's Health and Family Planning Statistical Yearbook for 2000 to 2014 were used to analyze the relationship between mortality associated with suicide and mental disorders. The analyses found that mortality among people with mental disorders dropped from 5.42/10 million in 2000 to 2.68/10 million in 2014, decreased more among females than males, and differed between urban and rural areas; that suicide mortality dropped from 10.79/10 million in 2000 to 6.79/10 million in 2014; the decrease was greater in women than in men, with suicide being highest among male residents of cities; and no significant correlation was found between mortality among persons with mental disorders and suicide mortality. There was no correlation between suicide mortality and mental-disorder mortality during 2000 to 2014; however, overall mortality decreased more among females than males during this period.

Linking Psychological Strain and Suicide Ideation: A Test of the Mediating Effect of Self-Determination Among Chinese Workers

Psychosocial causes of suicidal ideation among those who do not have diagnosable mental illnesses remain largely unexplored. Synthesizing the strain theory of suicide and self-determination theory, this research tested a multiple mediator model linking psychological strain with suicidal ideation via three basic psychological need satisfaction. Data from 750 professional employees in China support for the partially mediated effects of psychological strain via need satisfaction of competence and relatedness. These findings contribute to understanding Chinese employees' suicidal ideation from positive psychology perspective that is distinct from what is known from psychopathology.

Behavior Characteristics and Risk Factors for Suicide Among the Elderly in Rural China

We examine the characteristics of suicide behavior and associated risk factors in the elderly in rural China, compared with the nonelderly. Paired case-control design and psychological autopsy were used for subject recruitment and data collection. The included cases were 104 suicides of the elderly aged 60 years or older, 86 suicides of the nonelderly, and sex- and age-paired controls from the same villages. Although the characteristics of suicide behavior were similar between the two age groups of victims, the elderly who died by suicide had a greater tendency to experience negative life events and not live with a spouse. Suicide of the nonelderly was associated with family history of suicide, poor social support, and impulsivity. The influence of negative life events on the risk of suicide was greater in the elderly. Thus, efforts for suicide prevention must be tailored to the needs of specific age groups.

Suicidal Ideation among the Chinese Elderly and Its Correlates: A Comparison between the Rural and Urban Populations

Background: As China is going through a profound aging process, the mental health of the elderly is becoming an issue. As in many other societies, the elderly in China is a population at high risk of suicide; Methods: Data for the study were taken from the Sample Survey of the Aged Population in Urban/Rural China (SSAPUR) accomplished in 2010 by the China Ministry of Civil Affairs. The valid sample for this study was composed of 18,683 individuals, including 9416 urban residents and 9267 rural residents both aged 60 or more years; Results: Logistic regression analyses showed that household income and expenditure, the number of children, chronic diseases, disability of daily living, depression, the frequency of visiting neighbors and having friends or relatives who can help or not had remarkable effects on the suicidal ideation among urban and rural old people. Gender, education, political affiliation, marital status and self-rated health status did not work on the dependent variable. However, some risk factors for suicidal ideation among the Chinese elderly were different between rural and urban regions; Conclusions: We should take different measures when facing the different groups of the elderly.

Who are likely to attempt suicide again? A comparative study between the first and multiple timers

BACKGROUND

Various explanations account for suicide incidents, and some patients continue to attempt afterwards and others never again. The suicide mortality rate increases with the number of serious attempts. The prevention of secondary attempt of suicide should be an important approach to reduce suicide mortality. However, the characteristics of the targeted population of repeated suicide attempters are understudied.

METHODS

This was a cross-sectional data collection from hospital emergency room from patients who had either attempted suicide for the first time (n=721) or for two or more times (n=70). The subjects were between 14 and 53years old and comprised 293 males and 498 females. In-depth interview was conducted for each suicide attempter with a semi-structural protocol. Demographic and social-psychological characteristics were compared between the two groups of suicide attempters. Logistic regression was used to identify independent predictors of multiple attempts.

FINDINGS

The two groups only differed in religion factor among demographic characteristics and multiple suicide attempters group have a higher percentage of subjects who reported to have a religion affiliation than first time suicide attempters. Multiple attempters were more likely to have family suicide history, physical illness, mental disorder, higher scores on Beck Hopelessness Scale (BHS) and Suicide Intent Scale (SIS) and lower scores on Duke Social Support Scale (DSSI). In the final regression model, family history of suicide, mental disorder, hopelessness and social support emerged as significant predictors of multiple suicide attempts.

CONCLUSION

Suicide attempters that have mental disorder, family history of suicide, higher level of hopelessness and lower level of social support are more likely to re-attempt suicide again. Social and clinical interventions may have to also focus on this sub-group of patients with these characteristics to effectively reduce suicide mortality rate.

Risk of re-attempts and suicide death after a suicide attempt: A survival analysis

BACKGROUND

Suicide is the primary cause of unnatural death in Spain, and suicide re-attempts a major economic burden worldwide. The risk factors for re-attempt and suicide after an index suicide attempt are different. This study aims to investigate risk factors for re-attempt and suicide after an index suicide attempt.

METHODS

This observational study is part of a one-year telephone management program. We included all first-time suicide attempters evaluated in the emergency department at Parc Taulí-University Hospital (n = 1241) recruited over a five-year period (January 2008 to December 2012). Suicide attempters were evaluated at baseline using standardized instruments. Bivariate logistic regression models were used to identify risk factors. Kaplan-Meier curves were used to compare the time to re-attempt between categorical variables. Comparisons were performed using Log-Rank and Wilcoxon tests. Variables with a p-value lower than 0.2 were included in a multivariate Cox regression model. Bivariate logistic regression models were considered to identify risk factors for suicide. The significance level was set to 0.05.

RESULTS

Suicide re-attempters were more likely diagnosed with cluster B personality disorders (36.8% vs. 16.6%; p < 0.001), and alcohol use disorders (19.8 vs. 13.9; p = 0.02). Several [1.2% (15/1241)] of them died by suicide. Attempters who suicide were more likely alcohol users (33.3% vs. 17.2%; p = 0.047), and older (50.9 ± 11.9 vs. 40.7 ± 16.0; p = 0.004).

CONCLUSIONS

Alcohol use, personality disorders and younger age are risk factors for re-attempting. Older age is a risk factor for suicide among suicide attempters. Current prevention programs of suicidal behaviour should be tailored to the specific profile of each group.

Life satisfaction and degree of suicide intent: A test of the strain theory of suicide

BACKGROUND

Various factors contribute to suicide. Psychological strains are hypothesized to precede suicidal thought and attempt. Life satisfaction can be a measure of relative deprivation strain and aspiration-reality strain.

AIMS

This study was to compare the suicide attempters with various levels of life satisfaction and find out how life satisfaction affects the degree of suicide intent among medically serious suicide attempters.

METHODS

Subjects for study were recruited in some rural counties in China. Interview data were from hospital emergency rooms with medically serious attempters of suicide (n=791). The subjects were aged between 15 and 54years and 293 males and 498 females. Face to face interview was conducted for each suicide attempter with a semi-structural protocol including life satisfaction, physical health, demographic, sociological, and psychological measures, as well as psychological strains.

FINDINGS

The multiple linear regression analysis showed that mental disorder, aspiration strain and relative deprivation strain were significant risk factors for high intent of suicide among suicide attempters. The interaction between the two psychological strains also indicated that both failed aspiration and self-perceived low economic status in village play an important role in suicidal intent.

CONCLUSION

Low level of life satisfaction is associated with strong intent for suicide. Lack of life satisfaction is exemplified by relative deprivation perceived by the individuals and the discrepancy between an individual's aspiration for life and his/her reality. The findings from the suicide attempt data in rural China support the Strain Theory of Suicide.

Medically Serious Suicide Attempters With or Without Plan in Rural China

Although previous studies have discussed the risk factors of unplanned suicide behavior in several countries, the unplanned suicide attempt in China was not explored in a large sample. We aim to look into the characteristics of unplanned suicide attempters in China and compare them with those suicide attempters with plans. Subjects were 791 medically serious suicide attempters aged 15-54 years in rural China. The sixth item of Beck's Suicide Intent Scale was used to estimate the planned and unplanned suicide attempt. Logistic regression analysis was performed to examine the factors related to planned or unplanned suicide attempt. The results showed that the planned suicide attempts were associated with higher education, hopelessness, and previous suicide act. The unplanned suicide attempt tends to be suicide by pesticide and store pesticide at home. A ban of lethal pesticides may be a method for suicide prevention in rural China.

Geographical and temporal variations in the prevalence of mental disorders in suicide: Systematic review and meta-analysis

BACKGROUND

In contrast to the previous studies reporting that most suicides occur among people with mental disorders, recent studies have reported various rates of mental disorders in suicide in different geographical regions. We aimed to comprehensively investigate the factors influencing the variation in the prevalence of mental disorders reported among suicide victims.

METHOD

The authors searched Embase, Medline, Web of Science, and the Cochrane Library to identify psychological autopsy studies reporting the prevalence of any mental disorders among suicide victims. A meta-regression analysis was conducted to identify the potential effects of geographical regions, the year of publication, measurements of personality disorder, measurements of comorbidity, and the ratio of females on the prevalence of mental disorders in addition to examining the heterogeneity across studies.

RESULTS

From 4475 potentially relevant studies, 48 studies met eligibility criteria, with 6626 suicide victims. The studies from East Asia had a significantly lower mean prevalence (69.6% [95% CI=56.8 to 80.0]) than those in North America (88.2% [95% CI=79.7-93.5]) and South Asia (90.4% [95% CI=71.8-97.2]). The prevalence of any mental disorder decreased according to the year of publication (coefficients=-0.0715, p<0.001).

LIMITATIONS

Substantial heterogeneities were identified within all subgroup analyses.

CONCLUSIONS

The prevalence of mental disorders among suicide cases seemed relatively low in the East Asia region, and recently published studies tended to report a lower prevalence of mental disorders. The link between the risk factors and suicide in the absence of a mental disorder should be examined in different geographical and sociocultural contexts.

Religion and Suicide Risk: A Systematic Review

Although religion is reported to be protective against suicide, the empirical evidence is inconsistent. Research is complicated by the fact that there are many dimensions to religion (affiliation, participation, doctrine) and suicide (ideation, attempt, completion). We systematically reviewed the literature on religion and suicide over the last 10 years (89 articles) with a goal of identifying what specific dimensions of religion are associated with specific aspects of suicide. We found that religious affiliation does not necessarily protect against suicidal ideation, but does protect against suicide attempts. Whether religious affiliation protects against suicide attempts may depend on the culture-specific implications of affiliating with a particular religion, since minority religious groups can feel socially isolated. After adjusting for social support measures, religious service attendance is not especially protective against suicidal ideation, but does protect against suicide attempts, and possibly protects against suicide. Future qualitative studies might further clarify these associations.

Global trends in teenage suicide: 2003-2014

The object of this article is to review the past decade of research on teenage suicide, with a particular emphasis on epidemiologic trends by age, gender and indigenous ethnicity. As such, a review of research literature from 2003 to 2014 was conducted via a comprehensive search of relevant psychological and medical databases. Wide gaps in our knowledge base exist concerning the true extent of teenage suicide due to lack of data, particularly in developing countries, resulting in a Western bias. The gender paradox of elevated suicidality in females with higher completed suicide rates in males is observed in teenage populations worldwide, with the notable exceptions of China and India. Native and indigenous ethnic minority teens are at significantly increased risk of suicide in comparison to general population peers. Often those with the highest need for mental health care (such as the suicidal adolescent) have least access to therapeutic support.Globally, suicide in teenagers remains a major public health concern. Further focused research concerning completed suicides of youth below the age of 18 is required across countries and cultures to understand more about risk as children progress through adolescence. Gender and ethnic variations in suicidality are embedded within cultural, historical, psychological, relational and socio-economic domains. Worldwide, the absence of child/adolescent-specific mental health policies may delay the development of care and suicide prevention. Overall, it is vital that clinicians adopt a holistic approach that incorporates an awareness of age and gender influences, and that cultural competency informs tailored and evaluated intervention programmes.

Religion and Completed Suicide: a Meta-Analysis

INTRODUCTION

Suicide is a major public health concern and a leading cause of death around the world. How religion influences the risk of completed suicide in different settings across the world requires clarification in order to best inform suicide prevention strategies.

METHODS

A meta-analysis using search results from Pubmed and Web of Science databases was conducted following PRISMA protocol and using the keywords "religion" or "religious" or "religiosity" or "spiritual" or "spirituality" plus "suicide" or "suicidality" or "suicide attempt". Random and fixed effects models were used to generate pooled ORs and I2 values. Sub-analyses were conducted among the following categories: young age (<45 yo), older age (≥45 yo), western culture, eastern culture, and religious homogeneity.

RESULTS

Nine studies that altogether evaluated 2339 suicide cases and 5252 comparison participants met all selection criteria and were included in the meta-analysis. The meta-analysis suggested an overall protective effect of religiosity from completed suicide with a pooled OR of 0.38 (95% CI: 0.21-0.71) and I2 of 91%. Sub-analyses similarly revealed significant protective effects for studies performed in western cultures (OR = 0.29, 95% CI: 0.18-0.46), areas with religious homogeneity (OR = 0.18, 95% CI: 0.13-0.26), and among older populations (OR = 0.42, 95% CI: 0.21-0.84). High heterogeneity of our meta-analysis was attributed to three studies in which the methods varied from the other six.

CONCLUSION

Religion plays a protective role against suicide in a majority of settings where suicide research is conducted. However, this effect varies based on the cultural and religious context. Therefore, public health professionals need to strongly consider the current social and religious atmosphere of a given population when designing suicide prevention strategies.

Suicides and medically serious attempters are of the same population in Chinese rural young adults

BACKGROUND

Suicide rates in China are among the highest in the world, although there has been a decreasing trend in the past few years. One practical approach to study the characteristics and risk factors of suicide is to interview the suicide attempters. It was to compare completed suicides with serious attempters that may shed lights on suicide prevention strategies.

METHOD

This is a combination of two case control studies for suicide completers and suicide attempters respectively. After a sample of suicides (n=392) and community living controls (n=416) were obtained and studied in rural China, we collected in the same rural areas data of suicide attempt and studied 507 medically serious attempters and 503 community counterparts.

RESULTS

Characteristics and previously observed risk factors were compared between the suicides and the attempters, and we found that the demographic characteristics and risk factors for the suicides were also for the medically serious attempters but at some lesser degrees for the attempters than for the suicides. It was especially true of suicide intent, deficient coping, negative life events, and impulsivity. While most of the demographic characteristics were not significantly different between the suicides and the attempters, most of the clinical variables could distinguish the two groups.

CONCLUSIONS

The suicide victims and the serious attempters could be of the same group of people who were at the edge of fatal self-injury, and the same clinical risk factors but of different degrees have divided them into the life and death groups.

Suicide risks among adolescents and young adults in rural China

Background: In China, suicide is one of the major causes of death among adolescents and young adults aged 15 to 34 years. Aim: The current study examines how risk factors vary by age groups in rural China, referring to those aged 15 to 24 years and those aged 25 to 34 years. Method: A case-control psychological autopsy (PA) study is conducted in sixteen counties from three Chinese provinces, including 392 suicide cases and 416 community living controls in the sample. Results: In China, young adults aged 25 to 34 years have a higher risk for suicide than adolescents aged 15 to 24 years, and it holds true even controlling for relevant social factors. In addition, age-related factors such as education, marital status, whether having children, status in the family, physical health, and personal income all have varying degrees of impact on suicide risks for rural youth. Conclusions: This study shows that there are some age-related risk factors for suicide at certain life stages and emphasizes that young adults in rural China aged 25 to 34 years have an increased risk of suicide as a result of experiencing more psychological strains with age.

Effects of life satisfaction and psychache on risk for suicidal behaviour: a cross-sectional study based on data from Chinese undergraduates

OBJECTIVES

To examine predictive power of psychache and life satisfaction on risks for suicidal ideation and suicide attempt among young people.

DESIGN

A cross-sectional study.

SETTING

Data were collected from an online survey in Wuhan, China.

PARTICIPANTS

5988 university students from six universities were selected by a stratified cluster sampling method.

PRIMARY AND SECONDARY OUTCOME MEASURES

Suicidal ideation and suicide attempt at some point of the students' lifetime were the outcomes of interest.

RESULTS

Students with suicidal ideation or attempted suicide reported a lower level of life satisfaction and high degree of psychache than counterparts without suicidal ideation or attempt. Regression analyses indicated that life satisfaction and psychache were significantly associated with the risk of suicidal ideation and the risk of suicidal attempt. Though psychache showed a relatively stronger predictive power than life satisfaction, the effect of the two factors remained significant when they were individually adjusted for personal demographic characteristics. However, when the two factors were included in the model simultaneously to adjust for each other, psychache could fully explain the association between life satisfaction and suicidal attempt. Life satisfaction remained to contribute unique variance in the statistical prediction of suicidal ideation.

CONCLUSIONS

Psychache and life satisfaction both have a significant predictive power on risk for suicidal behaviour, and life satisfaction could relieve the predictive power of psychache when suicidal behaviour is just starting. Shneidman's theory that psychache is the pre-eminent psychological cause of suicide is perhaps applicable only to a more serious form of suicidal behaviour.

Effects of community stress and problems on residents' psychopathology

The connection between community stress and problems and community residents' psychopathology is an understudied area, and a limited number of studies have reported inconsistent findings. This research aimed to estimate the effect of perceived social factors in the community environment on the residents' self-reported psychopathology. The study sample consisted of 2034 men and women from 16 selected rural counties in three provinces of China. The social factors in the village community were measured by the World Health Organization Multisite Intervention Study on Suicidal Behaviors (WHO SUPRE-MISS) scale of Community Stress and Problems. The sychological and mental health of the individuals was assessed by (1) suicidal thoughts, plans and attempts (National Comorbidity Survey Replication or NCS-R), (2) pro-suicide attitudes (General Social Survey or GSS), (3) depression (Center for Epidemiological Studies Depression Scale or CES-D) and (4) suicide ideation (Scale for Suicide Ideation or SSI). Multiple regressions were performed separately for each of the four psychopathologic traits with the scale of Community Stress and Problems as the major predicting variable and age, gender, education years, marital status, family annual income, family status in village and religion as the confounding correlates. It is found that community stress and problems generally increase rural Chinese residents' psychopathologies, especially issues in health care, housing and transportation, which play more important roles than others.

Relationship of Coping Styles with Suicidal Behavior in Hospitalized Asthma and Chronic Obstructive Pulmonary Disease Patients: Substance Abusers versus Non- Substance Abusers

BACKGROUND

Treatment of patients with chronic conditions requiring hospitalization requires patient acceptance and cooperation and adoption of coping strategies. Inappropriate coping strategies such as substance abuse are concerning in the course of treatment. This study sought to explore the association of coping strategies with suicidal behavior in substance abusers and non substance abuser patients with chronic pulmonary diseases namely asthma and chronic obstructive pulmonary disease (COPD).

MATERIALS AND METHODS

This comparative study was performed on 100 patients with asthma and COPD selected via convenience sampling. Subjects with and without substance abuse were separated into two groups of 50 patients each. Ways of Coping Questionnaire of Lazarus (WOCQ) and Suicide Behavior Questionnaire-Revised (SBQ-R) were completed by them. Five Persian speaking patients rated this questionnaire to be easily understandable in the pre-test stage. Cronbach's alpha was calculated to measure the internal consistency.

RESULTS

The mean (±standard deviation) age of participants was 40 (±14) years; 58% of individuals were men; 62% had chosen problem-focused coping. The most abused substances were cigarettes (78%) and opium (42%); 6% of substance abusers had thought about suicide five times or more in the past year; 5% of substance abusers had seriously attempted suicide. Tendency to commit suicide was greater in men, substance abusers and participants who had chosen emotion-focused coping strategies, based on a regression model. Average score of suicide tendency was significantly higher in substance abusers (B=2.196, P =0.007).

CONCLUSION

Chronic disease is a crisis and patients need to acquire appropriate coping strategies to deal with it, especially in substance abusers and suicidal patients. Precise recognition of coping strategies in chronic pulmonary patients with substance abuse is necessary via a team cooperation among psychiatrics, psychologists and an internal physician in hospitals because medical treatment alone is not sufficient in such cases.
