Risk factors associated with suicide attempt in young French people

Characteristics of Single vs. Multiple Suicide Attempters Among Adult Population: A Systematic Review and Meta-Analysis

PURPOSE OF REVIEW

We aimed to examine the factors that differentiate single and multiple suicide attempters in adult population. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to conduct this review and meta-analysis. The review protocol was registered in PROSPERO. We carried out a systematic literature search in three databases to identify original studies that explored the differences between single and multiple suicide attempters among adult population.

RECENT FINDINGS

There might be meaningful differences between those individuals that attempt suicide once in their lifespan and those who make multiple attempts in terms of sociodemographic and clinical characteristics. There are no previous meta-analysis addressing this topic in the adult population. A total of 75 studies were included in the review and 69 were included in the meta-analysis. Multiple attempters were more likely to present certain disorders such as mood and psychotic disorders, as well as personality or substance use disorders. Higher suicide ideation and suicide intent scores also characterized this group. Childhood trauma experiences, stressful life events, and higher rates of hopelessness were statistically significant in multiple attempters. Identifying the factors predicting multiple suicide attempts helps to delineate a high-risk suicidal profile that should be taken into account in the clinical and suicide prevention scenario.

Prevalence and risk factors of suicide attempts in young, first-episode and drug-naïve Chinese Han outpatients with psychotic major depressive disorder

This study investigates the relationship between psychotic symptoms and suicide attempts in young first-episode, drug-naive Chinese Han outpatients diagnosed with Major Depressive Disorder (MDD). The prevalence of Psychotic Major Depressive Disorder (PMD) was found to be 8.3% among the enrolled MDD patients. The study assessed 1289 participants using various scales to evaluate the severity of clinical symptoms, including the CGI-S, the HAMD, the HAMA, and the PANSS positive subscale. Additionally, thyroid hormone and glucolipid metabolism indicators were examined. The findings indicate that among patients with PMD, 41.12% had recent suicide attempts, while 6.54% had previous suicide attempts. Patients who recently attempted suicide exhibited higher scores on the HAMA and CGI scales, along with elevated serum levels of Thyroid-Stimulating Hormone (TSH) and total cholesterol (TC), as well as higher systolic and diastolic blood pressure. Notably, TSH levels independently correlated with recent suicide attempts in PMD patients, with an impressive area under the receiver operating characteristic curve (AUROC) of 0.923. Furthermore, the subgroup of patients with previous suicide attempts displayed longer illness duration and higher HAMD scores. Duration of illness and HAMD were found to be independently associated with previous suicide attempts among PMD patients, with a combined predictive effect showing a robust AUROC of 0.910. In conclusion, this study highlights the significant prevalence of recent and previous suicide attempts among young Chinese Han outpatients with PMD. The identification of risk factors, especially the link between TSH levels and recent suicide attempts, offers valuable insights for clinicians to develop targeted interventions and preventive strategies for this vulnerable patient population.

Suicide attempt rate and the risk factors in young, first-episode and drug-naïve Chinese Han patients with major depressive disorder

BACKGROUND

In recent years, the rates of suicide among young people have been increasing, and major depressive disorder (MDD) is regarded to be its main cause. Many factors such as thyroid dysfunction and metabolic abnormalities are thought to mediate this process, but the conclusions are inconsistent. This study investigated the rate of suicide attempts and associated risk factors among young, first-episode and drug-naïve Chinese Han patients with MDD.

METHODS

A total of 917 patients with MDD (aged 18 ~ 35 years) were recruited. Demographic and clinical data were collected and thyroid function, fasting blood glucose and lipid profiles were measured. The Hamilton Depression Rating Scale-17 items (HAMD-17), Hamilton Anxiety Rating Scale (HAMA), positive symptom subscale of Positive and Negative Syndrome Scale (PANSS) and clinical global impression of severity scale (CGI-S) were adopted to assess depression, anxiety, psychotic symptoms and disease severity respectively.

RESULTS

The rate of suicide attempts was 19.5% in young MDD patients. There were significant differences in age (p = 0.003), education level (p = 0.001), age of onset (p = 0.004) and disease duration (p = 0.001) between patients with and without suicide attempts. Compared with patients without suicide attempts, patients with suicide attempts had significantly higher scores on the HAMD-17, HAMA, PANSS positive symptom subscale and CGI-S (all p < 0.001). Patients with suicide attempts had significantly higher levels of TSH (p < 0.001), TgAb (p = 0.004), TPOAb (p < 0.001), TG (p = 0.016), TC (p < 0.001), LDL (p < 0.001), and fasting glucose (p < 0.001), but significantly lower levels of HDL (p < 0.001). Logistic regression analysis showed that marital status (OR = 0.515, 95%CI: 0.280-0.950, p = 0.515), disease duration (OR = 1.100, 95%CI: 1.013-1.194, p = 0.024), HAMA score (OR = 1.313, 95%CI: 1.205-1.430, p < 0.001), CGI-S score (OR = 1.875, 95%CI: 1.339-2.624, p < 0.001), levels of FT3(OR = 0.717, 95%CI: 0.536-0.959, p = 0.025), TPOAb (OR = 1.004, 95%CI: 1.002-1.006, p < 0.001), TC (OR = 1.330, 95%CI: 1.011-1.750, p = 0.042) and LDL (OR = 0.736, 95%CI: 0.558-0.971, p = 0.030) were all independently associated with suicide attempts in young MDD patients.

CONCLUSIONS

In China, the rate of suicide attempts in young patients with MDD is quite high and thyroid dysfunction and metabolic abnormalities may be implicated in its pathogenesis.

A clinical study of suicide in patients admitted in psychiatry unit in Assiut University

Background

This study was performed for clinical study of suicide including risk factors in psychiatric patients admitted in psychiatric unit of Assiut University Hospital (AUH).

Results

We found that frequency of suicidal attempts is more in MDD (major depressive disorder), bipolar disorders followed by schizophrenia. And frequency of suicidal attempts in patients with multiple previous attempts before this one was higher in patients with mood disorders (53.8%) than psychotic and substance-induced disorders (32.3%, 13.8% respectively), with statistically significant difference in patients with MDD as well as there was significant treatment outcome on suicidal behavior.

Conclusion

The frequency of suicidal attempts is more in MDD (major depressive disorder), bipolar disorders followed by schizophrenia. There was significant severity of suicidal behavior in patients with psychotic disorders in comparison to patients with substance-induced disorder or mood disorders.

Clinical Characteristics of the Suicide Attempters Who Refused to Participate in a Suicide Prevention Case Management Program

Case management interventions for suicide attempters aimed at helping adjust their social life to prevent reattempts have high nonparticipation and dropout rates. We analyzed the clinical characteristics of the group who refused to participate in the suicide prevention program in Korea. A total of 489 patients with a suicide attempt who visited Uijeongbu St. Mary's Hospital, the Catholic University of Korea, from December 2009 to December 2013 were analyzed. All patients were divided into the participation group (n = 262) and the refusal group (n = 227) according to their participation in the case management program. Demographic and clinical characteristics of each group were examined. Results showed that the refusal group had low risks for suicide in terms of risk factors related with psychopathologies and presenting suicide behavior. That is, the refusal group had less patients with co-morbid medical illnesses and more patients with mild severity of depression compared to the participation group. However, the refusal group had more interpersonal conflict, more isolation of social integrity, and more impaired insight about suicide attempt. The results suggest that nonparticipation in the case management program may depend upon the patient's impaired insight about the riskiness of suicide and lack of social support.

An Analysis of Parent-Female Adolescent Relationships in Female Adolescent Suicides

This study analyzed Turkish female adolescent-family relations, which is believed to be one of the significant factors in female adolescents' suicide attempts, from a multidimensional perspective. The Parent-Adolescent Relationship Inventory, a multidimensional evaluation tool based on the behavioral family-system approach was used as a research tool. The inventory consists of the concepts and techniques of behavioral theory, family system theory, and cognitive theory in parent-adolescent' problems and conflicts. Based on these theories, the parent-adolescent relations inventory (PARQ), involves three main dimensions: problem solving and communication skills, cognitive/internalized beliefs, and functions and structures in family systems. There are two forms of the inventory, the adolescent form and the parent form. Only the adolescent form of PARQ, including 284 items, was used in this research. The inventory also consists of 16 subscales. It was adapted into Turkish by Eryüksel (1996) . The subjects of the study were 52 female adolescents who had attempted suicide and were taken to the Emergency Department of The Faculty of Medicine in Çukurova University, and 52 normal female adolescents from two different secondary schools at the southern province in Turkey. The age range of the clinical and normal groups were 14–18 ([Formula: see text] = 16). The results of the study revealed that the general stress level of female adolescents who attempted suicide is higher than those of normal groups. The examination of family structures of these female adolescents made it clear that mothers were the mediator between fathers and adolescents. It was also observed that both mothers and fathers shared many somatic concerns.

[Practice of trauma and emergency units in delivering care to youth who attempt suicide--experiences from Provence]

Suicide attempts (SA) represent a significant public health problem and raise questions wih respect to the best, most appropriate methods for triage and the delivery of care. A prospective investigation to evaluate the quality of SA health care was carried out over a three month period within 18 hospitals having an emergency care unit. A total of 393 youth having attempted suicide were triaged and treated by these establishments during the period of the survey, with a large majority of them being girls (77%). Medicinal intoxication was the most often used method (85.1%). The criteria and regulations relating to the initial health care provided upon the patient's arrival were most followed, contrary to those concerning hospitalisation modalities and preparation for release following treatment. Factors explaining the implementation of these criteria were related to the type of emergency unit, the presence of a mental disorder and the duration of the patient's hospitalisation. These results show that several aspects of health care provided to young suicide attempters should be improved in Provence.

Suicidal ideation and suicide attempt in Polish adolescents: is it a suicidal process?

The objective of our study was to assess the prevalence and possible predictors of suicide attempts and ideation in the school population of adolescents in the city of Lodz.

METHOD

A self-administered anonymous questionnaire was distributed to a representative (random) sample of 1,663 students, aged 14 to 21 years. Adolescents reporting no suicide behaviour constitute the control group; characteristics of this group were compared to those of the group concerned, with exploration of the correlation between different variables in terms of relative risk, separately for suicidal ideation and suicide attempts.

RESULTS

About 31% of students reported suicidal ideation (SSI), and 8%--suicide attempts (SSA). Among the factors related to the highest relative risk of suicide attempts in the examined students and differentiated SSA and SSI, the most significant factor appeared to be previous psychiatric treatment and/or psychotherapy (OR = 9), run away from home (OR = 7), suicidal deaths among relatives and friends (OR = 6), drug abuse (OR = 5), and "fascination with death" (OR = 4).

CONCLUSIONS

There are separate predictors of suicide attempt and suicidal ideation in Polish adolescents. Suicidal ideation as a common phenomenon (occurring in every third pupil) probably should be included into the specificity of the puberty process and considered as a separate phenomenon from suicide attempt. The presence of previous psychiatric diagnosis is most strongly related to the occurrence of suicide attempts (including those repeated), but is not related to suicidal ideation.

Suicidality and substance misuse in first-admitted subjects with psychotic disorder

OBJECTIVE

The aim of this study was to examine the links between suicidality and substance misuse (abuse or dependence) in subjects with early psychosis.

METHOD

Data were collected on a sample of first-admitted subjects with psychosis (n=64).

RESULTS

More than 1 in 4 patients had a history of parasuicide, and more than 1 in 10 patients were referred to the psychiatric hospital after such an act. Parasuicide was more frequent in subjects with a history of drug misuse (OR=4, 95% CI= 1.1-14.0, P=0.03), and especially of polysubstance use (OR=6.6, 95% CI=1.2-34.7, P=0.03).

CONCLUSION

The association between substance misuse and suicidality found in subjects with psychosis is similar to that which exists in the general population. Since early psychosis is a high-risk period for substance misuse, subjects with incipient psychosis may be especially vulnerable to the devastating consequences of drug use with regard to increased risk of suicide.
