Suicide in adolescents: a worldwide preventable tragedy

Educational agents and institutions called into action in suicide prevention, intervention, and postvention

Introduction

Suicide is the second leading cause of death in the 15 to 29 age group worldwide, and is a severe public health problem. Adolescent and young adult individuals attend educational institutions which can play an essential role in detecting and preventing suicide. For this reason, the purpose of this research is to identify what educational institutions and agents are called into action in suicide prevention, intervention, and postvention.

Methods

The method of systematic review of the literature based on the PRISMA protocol was used. The review protocol was registered in PROSPERO (PROSPERO 2020 CRD42020189127). The systematic review yielded 66 articles published between 1990 and February 2023.

Results

The results show that a wide variety of educational stakeholders are required to intervene for suicide prevention, interventions and postvention between primary education and college. The study describes the different programs that have been provided, the countries in which they have been implemented and the agents who have been targeted. It also identifies gaps in the research on suicide in the educational field.

Discussion

Overall, educational suicide initiatives report positive effects on participants' understanding, attitudes, and beliefs regarding suicide and suicide prevention, although some studies have expressed some caution.

Patterns of Unnatural Deaths Among Children and Adolescents: Autopsy Study (2011-2018)

BACKGROUND AND AIMS

The problem of unnatural death in children is still relevant because of their vulnerability. This work aimed to describe the epidemiological profile and patterns of these medicolegal deaths in children and adolescents in northern Tunisia.

METHODS

We conducted a retrospective study from January 2011 to December 2018, within the Forensic Department of Charles Nicolle Hospital in Tunis. All children who died of unnatural causes were included (767 cases).

RESULTS

An overall male predominance was observed (sex ratio = 2.4). Accidental deaths represent the most common manner of death (81.4%) involving most frequently domestic accidents occurring in children aged between 1 and 4 years. In cases of suicide, the highest risk profile was a female child aged between 15 and 18 years. The suicide occurred most often in the victim's home with hanging representing the common means of suicide. For the criminal form, the most common means in those cases were stabbing and blunt injuries.

CONCLUSION

Our study delivered a broad picture of unnatural deaths among children in Tunisia. These deaths, largely absent from child survival initiatives presently on the global agenda, can be prevented if they are addressed strategically, as their injury prevention strategies differ from adults.

Gait difference between children aged 9 to 12 with and without potential depressive mood

BACKGROUND

It has been reported that depression has an impact on both temporal spatial parameters and walking kinematics in adults. Given the difference in the walking biomechanics between adults and children, this study aimed to compare the gait difference in children aged 9-12 with and without potential depressive mood (PDM).

METHODS

49 children were recruited from local primary schools. We measured participants' depression level using Depression Anxiety Stress Scale (DASS) and classified them into control (i.e., DASS depression subscale score = 0.6 ± 1.4; n = 23) or PDM group (i.e., DASS depression subscale score = 21.3 ± 5.3; n = 26). Video gait analysis was employed to assess temporal spatial parameters and sagittal plane kinematics during self-paced overground walking. Independent t tests or Mann-Whitney tests were used to compare the gait parameters between the two groups.

RESULTS

Participants exhibited similar gait speed, vertical oscillation of the centre of mass, stance time, swing time, step length, upper and lower limb kinematics between the two groups (p > 0.05). However, children with PDM displayed a greater head flexion than controls (p = 0.026; Cohen's d = 0.66; moderate effect).

SIGNIFICANCE

Children with PDM may present a more slumped posture during walking when compared with their counterparts. This kinematics difference can potentially be used as a biomechanical marker for detection of mood problems in this cohort.

Akutversorgung psychisch kranker Kinder und Jugendlicher: Eine Pilotstudie an 257 PatientInnen

Fragestellung

Nicht bewältigte Entwicklungsaufgaben, schwierige soziale Rahmenbedingungen, aber auch psychische Erkrankungen können in Krisen münden, die zu einer Akutvorstellung an der Kinder- und Jugendpsychiatrie (KJP) führen. Ziel der vorliegenden Studie war es eine repräsentative Inanspruchnahmepopulation akut vorstelliger Patienten zu untersuchen, um einen Überblick über die Nutzung des akutpsychiatrischen Angebotes in der Kinder- und Jugendpsychiatrie zu erhalten.

Methodik

Es handelt sich um eine retrospektive Analyse der aus dem Ersteinschätzungsblatt und aus dem Krankenhaus internen Datenverarbeitungssystem erhobenen Daten. Untersucht wurden akut vorstellige Kinder und Jugendliche an Salzburgs einzigem Akutspital mit Unterbringungsbereich für diese Altersgruppe.

Ergebnisse

Von den 257 vorstelligen Patienten waren 53,7 % weiblich. Signifikant häufiger werden Jungen wegen externalisierender Symptome oder Außenfaktoren, Mädchen hingegen wegen suizidaler Symptome vorstellig. Zumeist bestehen die Symptome länger als eine Woche, bei einem Teil der Patienten sogar länger als 6 Monate. 51 % der Kinder und Jugendlichen wurden stationär aufgenommen, 43,2 % aller Vorgestellten nach Unterbringungsgesetz. Im Unterbringungsbereich betrug die Aufenthaltsdauer im Mittel drei Nächte.

Schlussfolgerung

Viele Kinder und Jugendliche zeigen bei Akutvorstellung eine chronifizierte Symptomatik. Suizidalität war ein häufiger Vorstellungsgrund, weshalb eine Unterbringung oftmals indiziert war. Die Erarbeitung von Akutkonzepten, insbesondere primäre, sekundäre und tertiäre Suizidprävention aber auch der Ausbau von niederschwelligen Anlaufstellen zeigen sich als wesentliche Zukunftsherausforderungen für die Kinder- und Jugendpsychiatrie in Österreich.

Prevalence and risk factors for youth suicidality among perinatally infected youths living with HIV/AIDS in Uganda: the CHAKA study

BACKGROUND

Research from high income countries indicates that suicide is a major mental health care concern and a leading cause of preventable deaths among children and adolescents. Proper assessment and management of youth suicidality is crucial in suicide prevention, but little is known about its prevalence and associated risk factors in Sub-Saharan Africa. In low income countries there is an increased risk of suicide among persons with HIV/AIDS even in the presence of the highly active antiretroviral therapy.

OBJECTIVE

To determine the prevalence of and risk factors for youth suicidality among perinatally infected youth living with HIV/AIDS in Uganda.

METHODS

We studied 392 HIV positive children (5-11 years) and adolescents (12-17 years) and their caregivers in Kampala and Masaka districts. Caregivers were administered the suicide assessment section of the MINI International Psychiatric Interview. Socio-demographic characteristics, psychiatric diagnoses, and psychosocial and clinical factors were assessed and suicidality (suicidal ideation and or suicidal attempt) was the outcome variable. Logistic regression was used to calculate odds ratios adjusting for study site and sex at 95% confidence intervals.

RESULTS

Caregivers reported a suicidality rate of 10.7% (CI 8-14.1) in the past one month with higher rates among urban female (12.4%, CI 8.6-17.7) than male (8.7%, CI 5.4-13.8) youth. Lifetime prevalence of attempted suicide was 2.3% (n = 9, CI 1.2-4.4) with the highest rates among urban female youth. Among children, caregivers reported a lifetime prevalence of attempted suicide of 1.5%. The self-reported rate of attempted suicide in the past month was 1.8% (n = 7, CI 0.8-3.7) with lifetime prevalence of 2.8% (n = 11, CI 1.6-5.0). The most common methods used during suicide attempts were cutting, taking overdose of HIV medications, use of organophosphates, hanging, stabbing and self-starvation. Clinical correlates of suicidality were low socioeconomic status (OR = 2.27, CI 1.06-4.87, p = 0.04), HIV felt stigma (OR = 2.10, CI 1.04-3.00, p = 0.02), and major depressive disorder (OR = 1.80, CI 0.48-2.10, p = 0.04). Attention-deficit/hyperactivity disorder was protective against suicidality (OR = 0.41, CI 0.18-0.92, p = 0.04).

CONCLUSION

The one-month prevalence of suicidality among CA-HIV was 10.7%.

Exploring the association between depression, suicidality and serum neurotrophin levels in adolescents

Objective: The aim of this study was to identify potential differences in serum brain-derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF), nerve growth factor (NGF) and neurotrophin-3 (NTF3) levels in adolescents with major depressive disorder (MDD) compared to healthy controls. The possible relationship between serum neurotrophin levels and suicidality in adolescents with MDD was also addressed.Methods: A total of 70 treatment-free adolescents with MDD and 40 healthy controls aged 11 to 19 years were enrolled. The severity of suicidality was determined using the Columbia-Suicide Severity Rating Scale, and the severity of depression and anxiety symptoms were evaluated by self-report inventories. Serum levels of neurotrophins were measured using an enzyme-linked immunosorbent assay.Results: The mean serum BDNF levels were significantly higher in adolescents with MDD than in control subjects; no significant difference was found between the groups for serum GDNF, NGF and NTF3 levels. No correlations were found between the levels of serum neurotrophins and the severity of depression or suicidality.Conclusions: The study results suggest that elevated serum BDNF levels may be related to MDD in adolescents. However, our findings did not support a role for neurotrophins in suicidality.Key pointsSerum BDNF levels were higher in adolescents with MDD than in controls.No significant alterations of serum levels of GDNF, NGF and NTF3 were evident in adolescents with MDD.Neurotrophin levels were not associated with suicidal ideation and behaviours.

The magnitude of suicidal ideation, attempts and associated factors of HIV positive youth attending ART follow ups at St. Paul's hospital Millennium Medical College and St. Peter's specialized hospital, Addis Ababa, Ethiopia, 2018

Background

Suicide which is considered a psychiatric emergency, is a serious cause of mortality worldwide. Youth living with HIV/AIDS (YLWHA) have higher rates of suicidal behavior than the general public. This study aimed to assess the magnitude and associated factors of suicide ideation and attempt among the Human Immune deficiency Virus (HIV) positive youth attending anti-retroviral therapy (ART) follow up at St. Paul`s hospital Millennium Medical College and St. Peter`s specialized hospital, Addis Ababa, Ethiopia.

Methods

In this cross-sectional study, 413 HIV positive youth were recruited for interviews, using the systematic random sampling technique. The Composite International Diagnostic Interview (CIDI) was used to assess suicide. PHQ-9, the Oslo social support and HIV perceived stigma scale instruments were used to assess the factors. We computed bivariate and multivariable binary logistic regressions to assess factors associated with suicidal ideation and attempt. Statistical significance was declared at P-value <0.05.

Result

The magnitude of suicidal ideation and attempts were found to be 27.1% and 16.9%, respectively. In the multivariate analysis, female sex (adjusted odd ratio(AOR) = 3.1, 95% CI, 1.6–6.0), family death (AOR = 2.1, 95%CI 1.15–3.85), WHO clinical stage III of HIV (AOR = 3.1 95% CI 1.3–7.35), WHO clinical stage IV of HIV (AOR = 4.76, 95%CI, 1.3–7.35), co-morbid depression (AOR = 7.14, 95%CI, 3.9–12.9), and perceived HIV stigma (AOR = 4.2, 95%CI, 2.27–8.2) were significantly associated with suicidal ideation, whereas female sex (AOR = 4.12, 95%CI, 1.82–9.78), opportunistic infections (AOR = 3.1, 95%CI, 1.6–6.04), WHO clinical stage III of HIV (AOR = 3.1 95%CI 1.24–7.81), co-morbid depression (AOR = 5.6 95% CI, 2.8–11.1), and poor social support (AOR = 3.4, 95%CI, 1.2–9.4) were statistically significant with suicidal attempt. The result suggests that the magnitude of suicidal ideation and attempts among HIV positive youth were high. We recommend that clinicians consider youth with comorbid depression, perceived HIV stigma and poor social support.

Deliberate Self-harm among Young People Begins to Increase at the Very Early Age: a Nationwide Study

BACKGROUND

Suicide in young people is one of most common cause of death; and deliberate self-harm (DSH) is important indicator of suicide. It is currently unclear how old the rate begins to increase or when it reaches to the same level with adults. The purpose of this study was to find beginning age of DSH and compare their characteristics with adults.

METHODS

This study retrospectively reviewed 5 years of nationwide prospective registry named Emergency Department-based Injury In-depth Surveillance (EDIIS) registry composed of all injured patients who were admitted to twenty tertiary university hospital emergency departments. Injured patients aged 29 years or younger from January 1, 2011 to December 31, 2015 were included. Incidence rate of DSH in all age was described. Patients were stratified by age: early teenage (11-15 years), late teenage (16-19 years), and early adulthood (20-29 years). Data of early teenage group were compared to those of other groups for examining their characteristics.

RESULTS

Among 588,549 injury patients, 8,400 patients reported DSH. The rate began to rise at age 11 and reach at age 16 which was equivalent to that of age 20 to 29. Early teenage had significantly higher excess mortality ratio based injury severity score (EMR-ISS) and had almost same level without significant difference in operation incidence or mortality compared to late teenage and early adulthood.

CONCLUSION

DSH rate began to rise at age 11, reaching adulthood level at age 16 in Korea.

Development and psychometric properties of the Suicidality of Adolescent Screening Scale (SASS) using Multidimensional Item Response Theory

Suicide prevention in adolescents by early detection using screening tools to identify high suicidal risk is a priority. Our objective was to build a multidimensional scale namely "Suicidality of Adolescent Screening Scale (SASS)" to identify adolescents at risk of suicide. An initial pool of items was developed by using in-depth interview, focus groups and a literature review. Initially, 77 items were administered to 307 adolescents and analyzed using the exploratory Multidimensional Item Response Theory (MIRT) to remove unnecessary items. A subsequent exploratory factor analysis revealed 35 items that collected into 4 factors: Stressors, Pessimism, Suicidality and Depression. To confirm this structure, a new sample of 450 adolescents were collected and confirmatory MIRT factor analysis was performed. The resulting scale was shown to be both construct valid and able to discriminate well between adolescents that had, and hadn't previous attempted suicide.

Factors affecting the decision to hospitalise children admitted to the emergency department due to non-fatal suicide attempts by pills

Objective:

Suicide attempts (SAs) in the paediatric age group represent an important cause of morbidity and mortality. Our aim was to examine the factors affecting the decision to hospitalize children with a diagnosis of non-fatal SA by pills.

Methods:

Children <18 years of age admitted with SA by pills during 2014 were evaluated retrospectively. Patients were divided into two groups: Group-I comprised hospitalised patients and Group-II included those who were discharged from the PED. These two groups were compared in terms of clinical and demographic characteristics recorded upon PED admission.

Results:

A total of 196 patients were included in the study. The number of pills taken for self-poisoning in Group-I (median: 20 pills) was higher than that in Group-II (median: 12 pills) (p < 0.001), and the rate of pathological findings during the first paediatric psychiatric consultation was higher in Group-I (91.1%) than in the Group-II (54.8%) (p < 0.001).

Conclusion:

Factors affecting the disposition decision in cases of children who performed non-fatal SA via pills included the amount of medication taken for the suicide attempt and the presence of psychiatric disorders, as determined by a paediatric psychiatrist during the acute phase.

Attempted Suicide Triggers in Thai Adolescent Perspectives

The study goal was to describe attempted suicide triggers in Thai adolescents. A descriptive exploratory qualitative study approach was used utilizing in-depth interviews with twelve adolescents who had attempted suicide and six of their parents. Content analysis was conducted. Attempted suicide triggers were (1) severe verbal criticisms and expulsion to die by a significant family member, (2) disappointed and unwanted by boyfriend in first serious relationship, (3) unwanted pregnancy, and (4) mental illness leading to intense emotions and irresistible impulses. These attempted suicide triggers should be of concern and brought into suicide prevention management programs such as emotional management, effective communication for adolescents and family.

Deaths due to hanging among adolescents - A 10-year retrospective study

The present study was carried out to analyze various factors associated with death due to hanging among adolescents and to identify the areas of intervention for preventing such deaths. A retrospective study was carried out on 51 cases of adolescent deaths due to hanging, the autopsies of which were conducted by the Department of Forensic Medicine, Dr Shankarrao Chavan Government Medical College, Nanded, Maharashtra State (India), during the period between 1 January 2001 and 31 December 2010. In the present study, death by hanging among the adolescent age group was most commonly suicidal (96.08%) in nature, and only two (3.92%) cases of deaths due to accidental hanging were observed. Of the total number of suicidal deaths due to hanging among adolescents, the majority (80.39%) were among the older adolescent (15-19 years) age group. Rope and clothing items were commonly used ligature materials for committing suicide by hanging. Females outnumbered male victims (M:F ratio 1:1.13) among adolescents, contrary to the male preponderance observed among victims of the older age group (M:F ratio 1:0.44). Most of the suicidal deaths due to hanging (83.67%) among adolescents were observed at the victims' home. The predisposing and precipitating factors observed were domestic strife, examination-related stress, and physical and psychological illness.

Gender-specific factors of suicide ideation among adolescents in the Republic of Korea: a nationally representative population-based study

The purposes of this study are to explore the differences in the rates of suicide ideation (SI) between male and female youths, and to investigate gender-specific factors strongly associated with SI. This study analyzed nationally representative secondary data, the Fourth Korea National Health and Nutrition Examination Survey collected over a 3 year period (2007-2009) (N=2358; youths aged 12-18 years). Significant differences in characteristics between adolescents with and without SI were analyzed using either t-test or chi-square test. After adjusting for demographics (i.e., age, monthly household income, and family intactness), gender-specific factors associated with SI were examined using multivariate logistic regression. Current research reveals that (a) the prevalence of SI is higher among female adolescents than among their male counterparts, (b) depression and stress are strong factors in both males and females, and (c) psychological counseling and experimentation with smoking and drinking are strong factors among females only. Different factors influencing SI between males and females should be considered when identifying youths at risk for SI and providing targeted interventions.

Suicide or accident? A psychological autopsy study of suicide in youths under the age of 16 compared to deaths labeled as accidents

OBJECTIVE

In the present paper, we describe suicide in youths under 16 years of age and compare their risk factors for suicide to those of older adolescents as described in the literature. Furthermore, we evaluate the possible mislabeling of suicides as accidents, and vice versa.

METHOD

We used the data from a nationwide psychological autopsy of youths 15 years and younger who had committed suicide or died in accidents in Norway from 1993 to 2004 (n = 84). We additionally constructed a suicide index to distinguish between the two causes of death.

RESULTS

The young suicide victims presented, with little gender difference, fewer obvious risk factors and less suicide intent than commonly described for older adolescents. The suicide index distinguished quite well between suicides and accidents, with few cases indicating a possible mislabeling, although some suicide cases could have been labeled as uncertain.

CONCLUSION

In line with previous research, suicides in 11-15-year-olds have many similarities to suicides in older adolescents in terms of external circumstances, but they present less apparent warning signs. In our total sample of 84 deaths, there were few indications of incorrect labeling.

Suicide mortality trends in young people aged 15 to 19 years in Lithuania

AIM

This paper considers the suicide mortality trends from 1990-2009 in young people aged 15 to 19 years in Lithuania.

METHODS

Suicide and injury mortality data, plus mortality data from all causes, were used to compare the trend lines.

RESULTS

Suicide mortality rate in young people aged 15-19 years and in all population showed a rising trend from 1990, and then a decreasing trend from 2002 year. This trend was significant exclusively in boys. When comparing suicide deaths as a percentage of injury deaths and of all deaths in the age group 15-19 years, rising trends for boys were evident, whilst in girls, there was no evidence of change.

CONCLUSIONS

In Lithuania, from early 1990s, the frequency of suicide increased amongst adults and young people aged 15-19 years. After 2002, a decrease in deaths by suicide was observed both for the whole population and for young people aged 15-19 years. The rise and fall was obvious for boys. The reasons for different trends may have been influenced by the political and socioeconomic instability in the 1990-2002 period, and the socioeconomic stability, together with active preventive measures, from 2002. Although the consumption of modern Selective serotonin reuptake inhibitors (SSRIs) increased during the same time, suicide mortality was again high during the economic crisis in 2008-2009.

Sex differences in adolescent depression: do sex hormones determine vulnerability?

Depression is one of the most common, costly and severe psychopathologies worldwide. Its incidence, however, differs significantly between the sexes, and depression rates in women are twice those of men. Interestingly, this sex difference emerges during adolescence. Although the adolescent period is characterised by major physical and behavioural transformations, it is unclear why the incidence of depression increases so dramatically in girls during this otherwise generally healthy developmental period. Although psychological and environmental factors are also involved, we discuss the neuroendocrinological factors determining adolescent vulnerability to depression. In particular, we address the role of sex steroids in mood regulation, hypothalamic-pituitary-adrenal axis maturation and sexual differentiation of the brain, with a focus on hippocampal plasticity.

A review and application of suicide prevention programs in high school settings

Teen suicide is a terrible tragedy and is the third leading cause of death among high school children aged 14 to 19. School based intervention programs have been regarded as an effective and essential means of addressing this problem. A comprehensive review of the extant literature provides examination of the risk and protective factors of suicide in this age group, the development of these programs, the current state of the science and recommendations for enhanced assessment and intervention.

Suicide risk in adolescents with chronic illness: implications for primary care and specialty pediatric practice: a review

Suicide in adolescents is a global tragedy. Research-identified correlates of suicide in youth include depression, academic failure, loss of friends, social isolation, and substance abuse, among others. This review focuses on the potential link between chronic illness in adolescents and increased suicide risk. Research suggests that chronic illness is a risk factor for depression in adolescents that may induce suicide ideation and attempts; however, this risk may be increased even more in young adulthood if the underlying causes of depression are not resolved. This risk needs to be considered against the research data noting an increase in suicide attempts and completions, in each decade of life from adolescence into adulthood. Although more research is clearly needed, it can be concluded that suicide risks are seen in adolescents with chronic illness and all of these young people should be screened for depression and other risk factors for suicide on a regular basis.

Brain-derived neurotrophic factor and suicide pathogenesis

Abstract Suicide is a major public health concern. The etiology and pathogenic mechanisms associated with suicidal behavior are poorly understood. Recent research on the biological perspective of suicide has gained momentum and appears to provide a promising approach for identifying potential risk factors associated with this disorder. One of the areas that have gained the most attention in suicide research is the role of brain-derived neurotrophic factor (BDNF), which participates in many physiological functions in the brain, including synaptic and structural plasticity. Several studies consistently show that expression of BDNF is reduced in blood cells of suicidal patients and in brains of subjects who committed suicide. Recent studies also demonstrate abnormalities in the functioning of BDNF, because its cognate receptors (tropomycin receptor kinase B and pan75 neurotrophin receptor) are abnormally active and/or expressed in the post-mortem brains of suicide subjects. There is further evidence of the role of BDNF in suicide as numerous studies show a strong association of suicidal behavior with BDNF functional polymorphism. Overall, it appears that abnormalities in BDNF signaling may serve as an important biological risk factor in the etiology and pathogenesis of suicide.
