Assessing the risk of subsequent self-harm after hospitalisation for COVID-19 is critical for mental health care planning during and after the pandemic.

This study aims to compare the risk of admission to hospital for self-harm within 12 months following a COVID-19 hospitalisation during the first half of 2020, with the risk following hospitalisations for other reasons.

Using the French administrative healthcare database, logistic regression models were employed to analyse data from patients admitted to hospitals in metropolitan France between January and June 2020. The analysis included adjustments for sociodemographic factors, psychiatric history and the level of care received during the initial hospital stay.

Of the 96 313 patients hospitalised for COVID-19, 336 (0.35%) were subsequently admitted for self-harm within 12 months, compared to 20 135 (0.72%) of 2 797 775 patients admitted for other reasons. This difference remained significant after adjusting for sociodemographic factors (adjusted odds ratio (aOR) = 0.66, 95% CI: 0.59–0.73), psychiatric disorder history (aOR = 0.65, 95% CI: 0.58–0.73) and the level of care received during the initial hospital stay (aOR = 0.70, 95% CI: 0.63–0.78). History of psychiatric disorders and intensive care were strongly correlated with increased risk, while older age was inversely associated with self-harm admissions.

Hospitalisation for COVID-19 during the early pandemic was linked to a lower risk of subsequent self-harm than hospitalisation for other reasons. Clinicians should consider psychiatric history and intensive care factors in evaluating the risk of future suicide.

Most evidence on suicidal thoughts, plans and attempts comes from Western countries; prevalence rates may differ in other parts of the world.

This study determined the prevalence of suicidal thoughts, plans and attempts in high school students in three different regional settings in Kenya.

This was a cross-sectional study of 2652 high school students. We asked structured questions to determine the prevalence of various types of suicidality, the methods planned or effected, and participants’ gender, age and form (grade level). We provided descriptive statistics, testing significant differences by chi-squared and Fisher's exact tests, and used logistic regression to identify relationships among different variables and their associations with suicidality.

The prevalence rates of suicidal thoughts, plans and attempts were 26.8, 14.9 and 15.7%, respectively. These rates are higher than those reported for Western countries. Some 6.7% of suicide attempts were not associated with plans. The most common method used in suicide attempts was drinking chemicals/poison (18.8%). Rates of suicidal thoughts and plans were higher for older students and students in urban rather than rural locations, and attempts were associated with female gender and higher grade level – especially the final year of high school, when exam performance affects future education and career prospects.

Suicidal thoughts, plans and attempts are prevalent in Kenyan high school students. There is a need for future studies to determine the different starting points to suicidal attempts, particularly for the significant number whose attempts are not preceded by thoughts and plans.

Autoimmune thyroiditis is closely associated with major depressive disorder (MDD) and suicide attempts. However, few studies have examined this relationship.

The study aimed to assess the prevalence and correlates of suicide attempts in patients with first-episode drug-naïve (FEDN) MDD and autoimmune thyroiditis.

We recruited 1718 out-patients with FEDN MDD and assessed depressive, anxiety and psychotic symptoms with the Hamilton Rating Scale for Depression, Hamilton Rating Scale for Anxiety (HRSA) and Positive and Negative Syndrome Subscale positive subscale, respectively. The serum levels of free triiodothyronine, free thyroxine, thyroid stimulating hormone (TSH), antithyroglobulin, thyroid peroxidase antibody (TPOAb) and several other metabolic parameters were assessed. Patients were divided into non-autoimmune thyroiditis, autoimmune thyroiditis only and autoimmune thyroiditis with abnormal TSH groups, based on autoimmune thyroiditis severity. Multiple logistic regression model was applied to identify the correlates of suicide attempts in patients with MDD and autoimmune thyroiditis with abnormal TSH.

Compared with the non-autoimmune thyroiditis group, the autoimmune thyroiditis with abnormal TSH group had a nearly fourfold higher likelihood of reporting a suicide attempt, whereas no difference was found between the non-autoimmune thyroiditis and autoimmune thyroiditis only groups. HRSA score, lnTPOAb and lnTSH were independently associated with suicide attempts in patients with autoimmune thyroiditis with abnormal TSH.

Patients with MDD and autoimmune thyroiditis with abnormal TSH are at higher risk for suicide attempt. TPOAb, TSH and anxiety are all independently associated with suicide attempts in this population, and regular thyroid checks are warranted.

Many autistic people in mental health are suicidal. This study evaluated the effectiveness of dialectical behavior therapy (DBT) v. treatment as usual (TAU) in reducing suicidal ideation and suicide attempts.

At six Dutch mental health centers, 123 outpatients (18–65 years) with DSM-5 diagnosed autism spectrum disorder (ASD) and suicidal behavior were randomly assigned to the DBT intervention group (n = 63) or TAU control group (n = 60). Assessments were conducted at baseline, post-treatment at 6 months and 12-month follow-up. The primary outcomes were severity of suicidal ideation and frequency of suicide attempts. The severity of depression and social anxiety were secondary outcomes.

At end-of-treatment, DBT significantly reduced both suicidal ideation (z = −2.24; p = 0.025; b = −4.41; s.e. = 197.0) and suicide attempts (z = −3.15; p = 0.002; IRR = 0.046; s.e. = 0.045) compared to TAU, but lost statistical significance at the 12-month follow-up. Depression severity significantly decreased with DBT (z = −1.99; p = 0.046: b = −2.74; s.e. = 1.37) remaining so at 12 months (z = −2.46; p = 0.014; b = −3.37; s.e. = 1.37). No effects were observed on social anxiety. Severe adverse events included two suicides in the TAU condition.

DBT is an acceptable, safe, and short-term effective intervention to reduce suicidal ideation and suicide attempts in autistic adults with suicidal behavior.

Suicide rates in adolescents with major depressive disorder (MDD) change with age and gender. Early adulthood is an important transitional stage between late adolescence and adulthood, in which an individual's mind gradually matures. However, there are fewer studies on prevalence and variables linked to the suicide attempts of young adults with MDD.

To explore gender differences in the prevalence and risk factors associated with suicide attempts in young adults with first-episode drug-naive MDD.

The Hamilton Rating Scale for Depression (HRSD), Hamilton Rating Scale for Anxiety (HRSA) and Positive Subscale of the Positive and Negative Syndrome Scale (PANSS) were used to assess depression, anxiety and psychotic symptoms respectively and various biochemical indicators were assessed.

Among 293 young adults with first-episode drug-naive MDD, the prevalence of suicide attempts was 15.45% (19/123) for males and 14.12% (24/170) for females. Males with suicide attempts had higher levels of thyroid-stimulating hormone (TSH) and higher PANSS Positive Subscale scores, whereas females with suicide attempts had higher TSH, serum total cholesterol, fasting blood glucose and diastolic blood pressure levels and higher scores on the HRSD, HRSA, PANSS Positive Subscale (all Bonferroni corrected P < 0.05). In males, PANSS Positive Subscale score (B = 0.17, P = 0.03, OR = 1.19, 95% CI 1.02–1.38) was a risk factor for suicide attempts.

There were significant gender differences in the risk factors for suicide attempts in young adults with first-episode drug-naive MDD.

Suicidal ideation and attempts are growing public health concerns globally. Evidence from high-income countries suggests that individuals with psychosis and bipolar disorder are at increased risk of suicidal ideation and attempts, but there is a scarcity of evidence from South Asia.

To estimate the prevalence of suicidal ideation and attempts in individuals with psychosis and bipolar disorder in South Asia.

In this systematic review and meta-analysis, four databases (PsycINFO, Web of Science, EMBASE and Medline) were searched until December 2022. Pooled prevalence was estimated with random-effects models. Heterogeneity was quantified with the I2-statistic.

The pooled sample size across the 21 studies was 3745 participants, 1941 (51.8%) of which were male. The pooled prevalence of suicide attempts in South Asian people with either psychosis or bipolar disorder was 22% (95% CI 17–27; n = 15). The pooled prevalence of suicidal ideation with psychosis or bipolar disorder combined was 38% (95% CI 27–51; n = 10). Meta-regression, subgroup and sensitivity analysis showed that the pooled prevalence estimates for both suicide attempt and ideation remained unaffected by variations in critical appraisal ratings and study designs. Only one study reported data on suicide-related deaths.

One in four individuals diagnosed with psychosis or bipolar disorder have reported suicide attempts, whereas up to one in three have experienced suicidal ideation. These findings underscore the urgent need for clinicians to regularly assess and monitor suicidal ideation and attempts among individuals with these disorders in South Asia.

Suicide attempts are a moderately heritable trait, and genetic correlations with psychiatric and related intermediate phenotypes have been reported. However, as several mental disorders as well as major depressive disorder (MDD) are strongly associated with suicide attempts, these genetic correlations could be mediated by psychiatric disorders. Here, we investigated genetic correlations of suicide attempts with psychiatric and related intermediate phenotypes, with and without adjusting for mental disorders.

To investigate the genetic correlations, we utilized large-scale genome-wide association study summary statistics for suicide attempts (with and without adjusting for mental disorders), nine psychiatric disorders, and 15 intermediate phenotypes.

Without adjusting for mental disorders, suicide attempts had significant positive genetic correlations with risks of attention-deficit/hyperactivity disorder, schizophrenia, bipolar disorder, MDD, anxiety disorders and posttraumatic stress disorder; higher risk tolerance; earlier age at first sexual intercourse, at first birth and at menopause; higher parity; lower childhood IQ, educational attainment and cognitive ability; and lower smoking cessation. After adjusting for mental disorders, suicide attempts had significant positive genetic correlations with the risk of MDD; earlier age at first sexual intercourse, at first birth and at menopause; and lower educational attainment. After adjusting for mental disorders, most of the genetic correlations with psychiatric disorders were decreased, while several genetic correlations with intermediate phenotypes were increased.

These findings highlight the importance of considering mental disorders in the analysis of genetic correlations related to suicide attempts and suggest that susceptibility to MDD, reproductive behaviors, and lower educational levels share a genetic basis with suicide attempts after adjusting for mental disorders.

Although childhood maltreatment has been widely supported to be a robust predictor of suicide behaviours, the effects of different childhood maltreatment subtypes remain controversial and inconclusive. Moreover, whether the effects differ by sex in urban and rural adolescents is still unknown. This study aimed to quantify the associations between five subtypes of childhood maltreatment and different suicide behaviour involvement.

A multistage cluster sampling method was adopted from April to December 2021 for adolescents aged 12 to 18 across five representative provinces of China. The Childhood Trauma Questionnaire-Short Form was used to measure childhood maltreatment subtypes. Suicide behaviour involvement was classified as none group, suicide ideator, suicide planner and suicide attempter. Confounding variables include demographic characteristics, smoking, drinking alcohol, depression and anxiety.

Among a total of 18,980 adolescents, 2021 (10.6%) were suicide ideator, 1595 (8.4%) were suicide planner and 1014 (5.3%) were suicide attempter. Rural females had the highest proportion of suicide ideator (13.8%) and suicide planner (11.5%). Multinomial logistic regression analysis indicated that five childhood maltreatment subtypes were independently associated with suicide behaviours, except for associations between sexual abuse and suicide ideator as well as suicide planner (p > 0.05). Moreover, these associations differ by sex and residence. After adjusted for interactions of different subtypes, structural equation model indicated that the direct effects of childhood maltreatment subtypes on suicide behaviours from high to low were emotional abuse (β = 0.363, p < 0.001), physical abuse (β = 0.100, p < 0.001) and sexual abuse (β = 0.033, p = 0.003), while the effects of physical neglect and emotional neglect were not significant (p > 0.05).

Five subtypes of childhood maltreatment have specific and non-equivalence associations with suicide behaviours. Emotional abuse may have the strongest effect, and sexual abuse have an acute effect on suicide behaviours. Suicide prevention programs for Chinese adolescents could focus on those who experienced emotional, physical and sexual abuse. Furthermore, strategies should be tailored by sex and residence, and rural females deserve more attention.

To describe nurses’ experiences of caring for individuals who have attempted suicide in specialized palliative care and to describe if the care of these individuals changed after the suicide attempt.

A qualitative, descriptive study was conducted. Nine nurses working in specialized palliative care units were interviewed following a semi-structured interview guide. Conventional content analysis was used in the analysis process.

The results are presented in 3 categories: “A suicide attempt evokes strong emotions,” “Health-care efforts changed after the suicide attempt,” and “Experiences for the rest of working life.” Suicide attempts aroused emotions in nurses such as frustration, compassion, and feelings of being manipulated. The relationship between the nurse and the individual was strengthened after the suicide attempt, and their conversations became deeper and changed in nature. Health-care efforts relating to the individual increased after the suicide attempt.

The results of the study can create an awareness that the palliative process also includes the risk of suicide and can be used to create conditions for nurses to be able to handle questions about suicide without fear. The results of the study can be used as an “eye opener” to the fact that suicidality occurs in palliative care. In summary, there is a critical need for nursing education in suicide risk assessment and continued follow-up care for patients at risk of suicide within palliative care.

Cesarean delivery (CD) has been associated with postpartum psychiatric disorders, but less is known about the risk of suicidal behaviors. We estimated the incidence and risk of suicide attempts and deaths during the first postpartum year in mothers who delivered via CD v. vaginally.

All deliveries in Sweden between 1973 and 2012 were identified. The mothers were followed since delivery for 12 months or until the date of one of the outcomes (i.e. suicide attempt or death by suicide), death by other causes or emigration. Associations were estimated using Cox proportional hazards regression models.

Of 4 016 789 identified deliveries, 514 113 (12.8%) were CDs and 3 502 676 (87.2%) were vaginal deliveries. During the 12-month follow-up, 504 (0.098%) suicide attempts were observed in the CD group and 2240 (0.064%) in the vaginal delivery group (risk difference: 0.034%), while 11 (0.0037%) deaths by suicide were registered in the CD group and 109 (0.0029%) in the vaginal delivery group (risk difference: 0.008%). Compared to vaginal delivery, CD was associated with an increased risk of suicide attempts [hazard ratio (HR) 1.46; 95% CI 1.32–1.60], but not of deaths by suicide (HR 1.44; 95% CI 0.88–2.36).

Maternal suicidal behaviors during the first postpartum year were uncommon in Sweden. Compared to vaginal delivery, CD was associated with a small increased risk of suicide attempts, but not death by suicide. Improved understanding of the association between CD and maternal suicidal behaviors may promote more appropriate measures to improve maternal mental well-being and further reduce suicidal risks.

Suicidal behavior remains an important clinical problem and a major cause of death in youth.

The purpose of this study was to describe the epidemiological and clinical profile of adolescents with suicide attempts.

This is a retrospective descriptive study that focused on a population of Tunisian adolescents aged between 10 and 19 years old and who were hospitalized after a suicide attempt between between January, 1st 2010 and November,15th 2018, in Razi Hospital.

We used a pre-established questionnaire that explored the sociodemographic and clinical data of patients.

Sixty adolescents were included in this study. The average age of the respondents was 14.3±2 years. The sex-ratio (m/f) was 0, 36. The suicidal adolescent was a female (73%), single (98%), enrolled in school (66%) with school failure history (52%). Family history of suicide was reported in 8%. Fifty adolescents (83%) lived with their parents and the relationship with them was described as disturbed in 60% of them. A history of physical and sexual abuse was reported in 25% during first adolescence and 15% during second adolescence. The most frequent diagnoses were adjustment disorder with depressed mood (45%) and depression (28%). Drug ingestion was the most common mean of suicide (63%), in an impulsive way in 82% of cases.

Development of repeated epidemiological surveys makes it possible to better understand the prevalence of suicide attempts in adolescents and to implement suicide prevention programs.

No significant relationships.

Suicide attempts in late adolescence deserves special attention.

Identifying particularities of suicidal behavior in this age group seems important in order to detect suicidal ideations.

Describe the characteristics of suicide attempts in late adolescence among hospitalized patients.

This is a retrospective descriptive study that was conducted in our psychiatry department in Razi Hospital, Tunisia. It focused on a population of Tunisian adolescents aged between 15 and 19 years old and who were hospitalized after a suicide attempt between January, 1st 2010 and November,15th 2018.We used a pre-established questionnaire that explored the sociodemographic and clinical data of patients.

Thirty adolescents were included. Twenty-three of them (77%) were female. Mean age of suicidal adolescents was 16.5 years. They were mostly living with their families (80%). Intentional drug ingestion was reported in 56% of cases. Half of the adolescents were indifferent regard the suicide attempt. Conflictual family environment was reported to be a triggering factor of the suicidal thoughts in 60% of cases, and romantic breakup in 20% of cases. In fact, these adolescents were diagnosed with adjustment disorder with depressed mood in 47% of them and depression (28%).Adolescent suicide attempts were correlated with a conflictual family environment (p=0.04) and the presence of academic difficulties (p<10-3).

Family dysfunction and conflictual environment are predictors of suicide risk in the late adolescence. Prevention strategies should be reviewed and focus more on these factors.

No significant relationships.

The transition from military service to civilian life is a high-risk period for suicide attempts (SAs). Although stressful life events (SLEs) faced by transitioning soldiers are thought to be implicated, systematic prospective evidence is lacking.

Participants in the Army Study to Assess Risk and Resilience in Servicemembers (STARRS) completed baseline self-report surveys while on active duty in 2011–2014. Two self-report follow-up Longitudinal Surveys (LS1: 2016–2018; LS2: 2018–2019) were subsequently administered to probability subsamples of these baseline respondents. As detailed in a previous report, a SA risk index based on survey, administrative, and geospatial data collected before separation/deactivation identified 15% of the LS respondents who had separated/deactivated as being high-risk for self-reported post-separation/deactivation SAs. The current report presents an investigation of the extent to which self-reported SLEs occurring in the 12 months before each LS survey might have mediated/modified the association between this SA risk index and post-separation/deactivation SAs.

The 15% of respondents identified as high-risk had a significantly elevated prevalence of some post-separation/deactivation SLEs. In addition, the associations of some SLEs with SAs were significantly stronger among predicted high-risk than lower-risk respondents. Demographic rate decomposition showed that 59.5% (s.e. = 10.2) of the overall association between the predicted high-risk index and subsequent SAs was linked to these SLEs.

It might be possible to prevent a substantial proportion of post-separation/deactivation SAs by providing high-risk soldiers with targeted preventive interventions for exposure/vulnerability to commonly occurring SLEs.

The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented global health crisis that may cause mental health problems and heighten suicide risk. We investigated the impact of the COVID-19 pandemic on trends in suicide attempts and suicide deaths in New Taipei City, Taiwan.

The current study used the official daily data on suicide attempts and deaths in New Taipei City, Taiwan (4 million inhabitants) between 2015 and 2020 from the Taiwan National Suicide Prevention Reporting System. Interrupted time-series (ITS) analyses with parameters corrected by the estimated autocorrelations were applied on weekly aggregated data to examine whether the suicide trends during the early COVID-19 pandemic (late January to July 2020) deviated from previous trends (January 2015 to late January 2020). The impact due to the suicide prevention policy change was also examined (since August 2020).

ITS analyses revealed no significant increases in both mean and trend on weekly suicide deaths during the COVID-19 pandemic and after the policy change. In contrast, there was a significant increasing trend in weekly suicide attempts since the COVID-19 outbreak at the rate of 1.54 attempts per week (95% confidence interval 0.49–2.60; p = 0.004). Sex difference analysis revealed that, however, this increasing trend was observed only in females not in males.

The COVID-19 pandemic has different impacts on suicides attempts and deaths during the early pandemic in New Taipei City, Taiwan. The COVID-19 outbreak drastically increased the trend of suicide attempts. In contrast, the number of suicide deaths had remained constant in the investigated periods.

Patients with substance use disorders (SUD) have higher alexithymia levels and present frequently suicidal ideation (SI) and suicide (SA) [1,2]. Beside, alexithymia has been related to suicidal behaviors in several psychiatric disorders[3]. Although, there are some studies on alexithymia and suicidality in SUD patients, to our knowledge there are no studies on this issue in Spanish population.

To compare the alexithymia levels in SUD patients with and without SI and SA in an outpatient addiction treatment center in Spain.

This is a cross-sectional study performed on 110 patients (74.3%males; mean age 43.6±14.5years old) for whom we had information from the Toronto Alexithymia Scale(TAS-20) and the presence or not of lifetime SI and SA.

Lifetime SI and SA were present in 55.5% and 35.5% of the sample respectively. The mean score of TAS-20, difficulties identifying feelings (DIF), difficulties describing feelings (DDT), and externally-oriented thinking(EOT) were 57.2±13.3, 20.0±7.0, 14.7±4.5, and 22.5±4.5 respectively.

SI and SA may be related to alexithymia levels. Hence, alexithymia should be further analyzed in SUD patients in longitudinal studies in order to analyze the bilateral association with suicidal spectrum behaviors.

Adolescent suicide and suicide attempts (SA) present a complex and multifactorial problem that deserves special attention. Identifying particularities of suicidal behavior in this age group is essential in order to identify suffering adolescents.

To determine the characteristics of adolescent suicide attempts compared to those of adults.

It was a retrospective study carried out on a clinical population who consult in the psychiatry department at the Gabes regional hospital during the period from January 1st, 2020 to September 30, 2020. Sociodemographic and clinical data of the patients as well as their family dynamics, their education, their personal and family history, characteristics of the SA and psychiatric symptoms preceding the act were assessed. We compared two subgroups: patients aged 10 to 19, and those aged 20 and over.

278 suicide patients were included. 101 of them were adolescents (10 -19 years), of which 89 (88.11%) were female. Mean age of suicidal adolescents was 16.5 years. They were mostly living with their families (92.07%). Intentional drug ingestion was more common in adolescents (81.1%) than in adults (40%). Adolescent suicide attempts were correlated with a conflictual family environment (p=0.04), exposure to mistreatment (p=0.001), the absence of underlying mental disorders (p<10-3), the presence of academic difficulties (p<10-3) and the presence of a precipitating factor such as family conflict (p<10-3) or school failure (p= 0.004).

A good knowledge of the particularities of suicidal behavior in adolescents is preliminary to support an effective preventive measure targeting both family and school environment

Seasonal changes, climatic factors such as temperature, sunlight intensity and precipitations as well as temporal factors seem to have an influence on suicidal behavior.

Our study aimed to analyse the association between seasonal changes, climatic variations, temporal factors and suicide attempts.

A retrospective descriptive and analytical study was undertaken including all patients consulting for the first time at Gabes psychiatry department from the 4th March 2009 to the 25th September 2020 for suicidal attempt. Sociodemographic and clinical data as well as suicidal attempts’ characteristics were assessed. Meteorologic data, related to the years 2009 through 2020, were obtained from the official weather website of Tunisia.

278 patients were collected, including 217 female. Mean age was 26. Suicidal patients were unmarried (75.9%), childless (79.1%) and unemployed (47.5%). Results showed that suicidal attempts occurred most frequently in summer (32.5%) specifically in June and July (10.9% for each). Regarding the distribution of suicide attempts over the days of the week, the highest rate was observed on Monday (22.5%) and the lower one on Friday. There were a correlation between high temperature and suicide attempt by hanging (p=0.006), between days of sunlight and manifestations preceding the suicidal attempt (p=0.04) and between rainfall and anxiety disorder leading to suicidal attempt (p=0.03).We finded also an association between the summer and risk behavior such as runaways (p=0.024).

A better identification of seasonality, climatic and temporal factors in suicidal behavior could allow a better prevention in suicidal attempts and a reduction in death by suicide

Bipolar disorder (BD) has the highest suicide attempt rate among psychiatric disorders. Many factors are associated with the risk of suicide attempt in BD, but the relation between them has still not been explicitly stated.

This study aimed to examine the clinical variables characterizing patients with BD with prior suicide attempt (PSA).

This was a descriptive and analytical study, conducted over 3 months, involving 31 euthymic patients with BD, followed up in the outpatient psychiatry department of Hedi Chaker University Hospital in Sfax (Tunisia). General, clinical and therapeutic data were collected using a pre-established questionnaire. Quality of life (QOL) was assessed with the «36 item Short-Form Health Survey» (SF-36). Impulsivity was assessed with the Barratt Impulsiveness Scale (BIS-11).

The mean age was 47.25 years and the sex ratio was 1.6. Family history of suicide attempts was found in 25% of cases. Mean score of SF36 was 34 and high degree of impulsivity was noted in 62.5% of cases. The frequency of BD patients with PSA was 12.3% (N=8), with two of these (25%) having more than one PSA. Comorbid alcohol abuse (p=0.000), somatic illness (p=0.013), high degree of impulsivity (p=0.032), and impaired quality of live (p=0.003) were significantly more frequent in BD patients with PSA.

We found several clinical variables associated with PSA in BD patients. Even though these retrospective findings did not address causality, they could be clinically relevant to better understanding suicidal behavior in BD and adopting proper strategies to prevent suicide in higher risk patients.

Among the postcrisis suicide prevention programmes, brief contact interventions (BCIs) have been proven to be efficient. VigilanS generalizes to a whole French region a BCI combining resource cards, telephone calls, and sending postcards, according to a predefined algorithm. However, a major problem in suicide prevention is the suicide reattempt, which can lead to final suicide. Here, we analyze the suicide reattempt in VigilanS.

The study concerned patients included in VigilanS over the period from January 1, 2015 to December 31, 2018, with an end of follow-up on July 1, 2019. We performed a series of descriptive analyses, survival curves, and regressions. The outcome was the suicide reattempt, and the predictive variables were the characteristics of the patient at entry and during follow-up in VigilanS. Age and sex were considered as adjustment variables.

A total of 11,879 inclusions occurred during the study period, corresponding to 10,666 different patients, among which 905 reattempted suicide. More than half were primary suicide attempters (53.4%). A significant relationship with suicide reattempt was identified for the following characteristics: being a non-primary suicide attempter, having attempted suicide by voluntary drug intoxication and phlebotomy, alcohol consumption among primary suicide attempters, and having no companion at the emergency room visit among non-primary suicide attempters. Hanging (as suicide method), having made no call to VigilanS were protective factors.

This study provides us with a valuable insight into the profiles of patients repeating a suicide attempts, which is important for suicide prevention in general.

While childhood externalizing, internalizing and comorbid problems have been associated with suicidal risk, little is known about their specific associations with suicidal ideation and attempts. We examined associations between childhood externalizing, internalizing and comorbid problems and suicidal ideation (without attempts) and attempts by early adulthood, in males and females.

Participants were from the Quebec Longitudinal Study of Kindergarten Children, a population-based study of kindergarteners in Quebec from 1986 to 1988 and followed-up until 2005. We captured the co-development of teacher-rated externalizing and internalizing problems at age 6–12 using multitrajectories. Using the Diagnostic Interview Schedule administered at age 15 and 22, we identified individuals (1) who never experienced suicidal ideation/attempts, (2) experienced suicidal ideation but never attempted suicide and (3) attempted suicide.

The identified profiles were no/low problems (45%), externalizing (29%), internalizing (11%) and comorbid problems (13%). After adjusting for socioeconomic and familial characteristics, children with externalizing (OR 2.00, CI 1.39–2.88), internalizing (OR 2.34, CI 1.51–3.64) and comorbid (OR 3.29, CI 2.05–5.29) problems were at higher risk of attempting suicide (v. non-suicidal) by age 22 than those with low/no problems. Females with comorbid problems were at higher risk of attempting suicide than females with one problem. Childhood problems were not associated with suicidal ideation. Externalizing (OR 2.01, CI 1.29–3.12) and comorbid problems (OR 2.28, CI 1.29–4.03) distinguished individuals who attempted suicide from those who thought about suicide without attempting.

Childhood externalizing problems alone or combined with internalizing problems were associated with suicide attempts, but not ideation (without attempts), suggesting that these problems confer a specific risk for suicide attempts.
