Features for medically serious suicide attempters who do not have a strong intent to die: a cross-sectional study in rural China

Psychosocial and Psychiatric Factors Associated with Expected Fatality during Suicide Attempt in Men and Women

BACKGROUND: Differential factors that influence intention and subjectively perceived fatality during non-fatal suicidal acts amongst men and women have rarely been explored in the extant literature. Exploring these factors may help to understand how they influence medical outcomes and may also be used in a post-crisis counselling. This study aims to assess factors influencing intent in relation to expected fatality during suicidal acts in men and women. METHOD: In the current study, 433 individuals who attempted suicide (age 24.890.98 years, male/female ratio=1.29) were surveyed using the WHO-5 Well-Being Index, Beck Depression Inventory, Beck Suicide Intent Scale, Plutchik Feelings and Acts of Violence Scale, and Spielberger State/Trait Anger Scale. Life stress was evaluated as an accumulation of negative life events, whilst psychiatric disorders were assessed using CIDI 2.1 inventory. RESULTS: It was found that the higher expected fatality was associated with higher suicide intention scores, whereas the medical severity of attempts and violent/non-violent attempts distribution did not differ between groups. Although there was no difference in suicide intent scores and medical severity between men and women, men demonstrated a 2.43.5 times higher proportion of violent attempts, depending on the group. Higher perceived fatality was associated with lower general well-being, higher depression and violence, hopelessness, and total life stress in men, whereas among women higher perceived fatality was only associated with total life stress. Moreover, in men and women, higher intent and expected fatality was associated with a differential set of negative life events that occurred during childhood. The prevalence of mental health disturbances in the entire sample was about 50% and equally distributed among men and women. However, addictions prevailed among men, while neurotic and stress-related disorders were more common among women. Among those who expected more fatality the number of people with diagnoses and comorbidity was higher, especially in men. CONCLUSION: There is a difference in risk factors for expected fatality and intent in men and women attempting suicide, which may not necessarily result in severe medical outcomes but may help during the post-crisis counseling of suicide attempters. Expected fatality deserves more attention as a component of general intent. An in-depth study of this phenomenon may help to understand motives of men and women attempting suicide and help prevent future suicidal attempts.

Association between new-onset Parkinson's disease and suicide risk in South Korea: a nationwide cohort study

BACKGROUND

Parkinson's disease (PD) is an increasingly common neurodegenerative disease in an aging society. Whether PD is associated with an increased suicide risk is unclear. Thus, we investigated the effect of new-onset PD on suicide.

METHODS

Using the National Health Insurance Service Senior Sample Cohort of South Korea, 17,143 incident PD patients and 17,143 risk set controls, matched by propensity score, were selected for follow-up. The incidence rate of suicide and 95% confidence interval (CI) were calculated based on a generalized linear model of the Poisson distribution. Effect sizes were expressed as hazard ratios (HRs) using the Cox proportional hazards model with a robust variance estimator that incorporated clustering within matched pairs.

RESULTS

The incidence rate of suicide was 206.7 cases per 100,000 person-years (95% CI, 172.8-246.9) among the PD cohort. Compared to the matched controls, patients with PD were 2.64 times (HR, 2.64; 95% CI, 1.31-5.30) more likely to commit suicide during the first 180 days of follow-up and 2.47 times (HR, 2.47; 95% CI, 1.42-4.28) within the first 365 days of follow-up. During the entire follow-up period, patients with PD were 2.26 times more likely to commit suicide than were their matched controls (HR, 2.26; 95% CI, 1.67-3.06).

CONCLUSION

Our findings indicated an increased risk of suicide in patients with new-onset PD, regardless of the period after diagnosis. Incorporating mental health care with social and environmental interventions into primary care and PD-specialized care can help reduce suicide risk in people with PD, improving suicide prevention, identification, and risk assessment.

Stronger psychological strains increase the odds of suicide death: A comparison between suicides and suicide attempters

AIM

This study was aimed to compare the psychological strains between suicides and suicide attempters, so as to verify the hypothesis whether the stronger psychological strains increase the odds of suicide death.

METHOD

The suicide data were collected by a psychological autopsy (PA) study, and the suicide attempt data were from the same rural areas in China. Information was obtained with face to face structured questionnaires interviews. A social value conflict scale, measures of aspiration and deprivation, and Moos's Coping Response Inventory (CRI) were used to measure psychological strains. The Spearman correlation and Logistic regression method were applied to analyse and estimate the odds ratio (OR) of fatality of suicide behaviours from psychological strains.

RESULTS

The value strain, aspiration strain, deprivation strain, and coping strain were all significantly stronger among the suicides than suicide attempters (P < 0.001). Each psychological strain had statistical correlation with suicide behaviour (P < 0.001). The univariable and multivariable Logistic regressions all indicated that rural residence, being never married, and the psychological strains were the independent lethality factors of suicidal behaviours.

CONCLUSIONS

Psychological strains were the independent lethality factors of suicide behaviours. Stronger psychological strains increase the odds of suicide death. The intervention based on the Strain Theory of Suicide could decrease the odds risk of suicide death.

Suicide in Elderly Patients with Hip Fracture: A South Korean Nationwide Cohort Study

BACKGROUND

The purpose of the present study was to evaluate the incidence rate (IR) of suicide in elderly patients with hip fracture on the basis of a nationwide cohort and to analyze the change in the hazard ratio for suicide after hip fracture over time in comparison with a control group.

METHODS

Patients with hip fracture and their matched controls were selected from the National Health Insurance Service-Senior cohort (NHIS-Senior) of the Republic of Korea. The NHIS-Senior consists of 558,147 people selected by a 10% simple random-sampling method from a total of 5.5 million subjects ≥60 years of age in 2002. Risk-set matching (1:2) on the propensity score was performed with use of a nearest neighbor matching algorithm with a maximum caliper of 0.1 for the hazard components. The IR of suicide and 95% confidence interval (CI) were calculated on the basis of a generalized linear model with a Poisson distribution. The effect size was presented as a hazard ratio (HR) with use of the Cox proportional-hazard model with a robust variance estimator that accounts for clustering within matched pairs.

RESULTS

A total of 11,477 patients with hip fracture and 22,954 matched controls were included. The mean duration of follow-up was 4.59 years, generating 158,139 person-years. During follow-up, a total of 170 suicides were identified. Comparisons at up to 180 days and 365 days showed that patients with hip fracture were at higher risk for suicide than matched controls (p = 0.009 and 0.004, respectively; stratified log-rank test). During the first 180 days of follow-up, 14 suicides were identified in patients with hip fracture during 11,152 person-years (IR, 266.1 per 100,000 person-years; 95% CI, 157.6 to 449.4). Patients with hip fracture were 2.97 times more likely to kill themselves than their matched controls during the same period (HR = 2.97; 95% CI, 1.32 to 6.69).

CONCLUSIONS

Hip fracture in elderly patients increased suicide risk within a year. A new approach to psychiatric evaluation and management is needed in elderly patients with hip fracture.

Relationship Between Buddhist Belief and Suicide Risk in Chinese Persons Undergoing Methadone Maintenance Therapy for Heroin Dependence

BACKGROUND

In western countries, there is a negative association between religious belief and suicide risk, while in China this association is positive. Nevertheless, few data are available on the association between one specific type of religion and suicide risk, which might be different from the overall positive religion-suicide association in China. This study examined the association between Buddhist belief and suicide risk in Chinese persons receiving methadone maintenance therapy (MMT) for heroin dependence.

METHODS

In total, 61 Buddhist believers and 425 age, gender, and clinic frequency-matched non-religious believers were selected from a sample of patients with heroin dependence treated in three MMT clinics in Wuhan, China. The suicidality module of the Chinese version of the Mini-international Neuropsychiatric Interview 5.0 was used to assess current suicide risk. Patients' demographic and clinical characteristics were also collected. Multiple ordinary logistic regression was used to analyze the association between Buddhist belief and current suicide risk, controlling for the confounding effects of demographic and clinical factors.

RESULTS

In Chinese patients receiving MMT for heroin dependence, Buddhist believers had significantly higher levels of current suicide risk than non-religious believers (low: 45.9% vs. 24.7%, medium: 4.9% vs. 3.5%, high: 19.7% vs. 12.5%, P < 0.001). After adjusting for demographic and clinical covariates (including depressive symptoms), Buddhist belief was still significantly associated with an increase in the level of current suicide risk (OR: 2.98, P < 0.001).

CONCLUSION

Buddhist belief is significantly associated with elevated current suicide risk in Chinese patients receiving MMT for heroin independence. In Chinese MMT clinics, patients with Buddhist belief may have a high current suicide risk and a timely psychiatric assessment and crisis intervention (when necessary) should be provided to these patients.
