Adolescent and children suicides in Turkey: Analysis of data from the Turkish Statistical Institute (2002-2022)

Suicides in children and adolescents have different characteristics from other age groups because of their unique physical and psychosocial dynamics. Having more information on childhood and adolescent suicides and knowing their characteristics will lead to the development of prevention strategies. This study aimed to evaluate demographic characteristics, suicide methods, and causes of suicides in individuals aged <19 years using 2002 and 2022 data from the Turkish Statistical Institute. Of 1746 suicide cases, 813 (46.6 %) were recorded in male teens and 933 (53.4 %) in female teens aged <15 years. Of 7698 suicide cases, 4041 (52.5 %) were reported in male teens and 3657 (47.5 %) in female teens aged 15-19 years. Family incompatibility was the most common cause of suicides in children and adolescents. The most common suicide method was hanging. Population data show a decreasing trend, particularly in developed and developing countries, among children and adolescents. Therefore, suicide is an important problem in children and adolescents, who constitute a critical dynamic population for the socioeconomic future of societies.

Network analysis of influential risk factors in adolescent suicide attempters

OBJECTIVE

This study aims to investigate the interrelationship of risk factors for suicidal behaviour and their influence on attempt severity in a sample of adolescents who have recently attempted suicide. For it a network analyse was performed.

METHOD

Data from a sample of adolescents from 12 to 17 years of age with documented suicide attempts were collected and analysed in the context of a larger study conducted in Spain called SURVIVE. Several factors were examined including age, sex, depression, trauma, impulsivity, and substance abuse. Graph analysis was performed to identify relationships and centrality measures among these factors.

RESULTS

A total of 267 participants were enrolled: 233 females and 34 males with a mean age of 15.00 years (SD = 1.52). The results indicate that age and sex do not have a notable relationship with attempt severity in adolescents. Emotional and behavioural difficulties, measured by the Strengths and Difficulties Questionnaire (SDQ), have the greatest influence on other variables. Depression and childhood trauma show varying degrees of association with suicidal behaviour, as does motor impulsivity. Substance use does not appear to be strongly related to suicide attempt severity. The number of suicide attempts is strongly correlated with emotional and behavioural difficulties, depression, and childhood trauma. Lethality of suicide attempts and intensity of suicidal ideation do not show significant associations with the other variables.

CONCLUSION

This study identifies significant risk factors for adolescent suicide. Emotional and behavioural symptoms, depression, and childhood trauma are strongly linked to suicidal behaviour. However, age, sex, and substance abuse show minimal correlation. Assessing emotional difficulties and depressive symptoms using specific questionnaires could be crucial in evaluating suicidal behaviour in adolescents.

Cross-sectional study about suicide ideation and attempts among Brazilian pre-adolescents

BACKGROUND

Suicide is a global public health problem. In childhood, the risk factors are less clear, highlighting family and individual factors. This study aims to investigate the prevalence and sociodemographic, social, family, and individual factors associated with suicide ideation and attempts in pre-adolescents in a Brazilian city.

METHODS

The sample comes from a cohort of 500 schoolchildren of a city in Rio de Janeiro/Brazil. The data are analyzed cross-sectionally. The research incorporated data from the years 2005, 2006, and 2008 to evaluate suicide ideation and attempts in childhood, as reported by parents/caregivers, teachers and children. A hierarchical logistic model evaluated the association between the explanatory variables related to sociodemographic, social, family, and individual factors and the outcome.

RESULTS

22.2% of the children (95% CI 18.0%-27.0%) had suicide ideation/attempts, reported either by their mothers, teachers, or the child at some point in a cohort. The following variables were associated with suicidal ideation/attempts in the final adjusted model: regular or poor quality of relationship with friends (OR = 1.84; 95% CI 1.31-2.58), having a family member incarcerated (OR = 1.44; 95% CI 1.07-1.92) and having worse performance in portuguese or mathematics than other students (OR = 2.05; 95% CI 1.29-3.26).

CONCLUSION

Suicidal behavior in childhood is severe and affects everyone around the case, demanding to promote friendships, helping with school activities, and providing greater support and attention to children at risk. Bad relationships with friends and incarcerated family members are particularly key risk factors for suicide ideation and attempts. It is essential to improve prevention policies and to disseminate protective behaviors. There is a critical need to augment community mental health resources, mainly in less developed countries and regions that lack these services.

Adverse childhood experiences (ACEs) and suicidal behaviors in emerging adulthood: The 1993 Pelotas birth cohort

BACKGROUND

Suicide is the second most common cause of death among young individuals (10-25 years). The risk of first occurrence of suicidal behavior increases significantly at the start of adolescence, highlighting the importance of research regarding the association between early life factors, such as adverse childhood experiences (ACEs), and suicidal behaviors.

OBJECTIVE

To assess if ACEs are prospectively associated with lifetime suicide attempt and suicidal thoughts at young adulthood.

PARTICIPANTS AND SETTING

Data from 3050 young adults from the 1993 Pelotas Birth Cohort.

METHODS

Discrimination (of any type), financial hardship, maternal common mental disorders (CMD - SRQ-20), parental death, parental divorce and physical abuse were assessed at the 11-year follow-up. Data regarding suicidal thoughts and suicide attempt was assessed at 22 years with Mini International Neuropsychiatric Interview (MINI), version 5.0. Crude and adjusted logistic regression models were estimated.

RESULTS

In the adjusted model, those who suffered financial hardship (OR 2.51; 95 % CI 1.66-3.79), parental divorce (OR 1.44; 95 % CI 1.02-2.04) and maternal CMD (OR 1.72; 95 % CI 1.21-2.46) at 11 years were more likely to report suicidal thoughts at 22 years. Also, those who experienced financial hardship (OR 1.71; 95 % CI 1.13-2.58), physical abuse (OR 1.48; 95 % CI 1.08-2.04), discrimination (OR 1.74; 95 % CI 1.20-2.51), maternal CMD (OR 1.67; 95 % CI 1.20-2.32), or parental divorce (OR 1.41; 95 % CI 1.02-1.94) were more likely to report a lifetime suicide attempt.

CONCLUSION

There was a strong association between financial hardship, maternal CMD and divorce during childhood, and suicidal thoughts, such as suicidal ideation or planning, at the beginning of adulthood. Financial hardship, discrimination, divorce, maternal CMD and physical abuse were associated with suicide attempt. These findings demonstrate that mental health support must be available following certain ACEs during childhood, alongside with ACEs prevention. More research is needed on the association between discrimination and suicide attempts, differentiating the nature and impact of each type of discrimination.

Risk and protective factors in suicidal behaviour among young people in Hong Kong: A comparison study between children and adolescents✰

Suicide is the leading cause of death among young people worldwide. Few studies examined the factors of childhood suicidality and compared them with adolescent suicidality to meet their age-specific needs. We examined the similarities and differences in risk and protective factors of children and adolescent suicidality in Hong Kong. A school-based survey with 541 students in grades 4-6 and 3,061 students in grades 7-11 from 15 schools was conducted. We measured the demographic, familial, school, mental health, and psychological factors of suicidality. Hierarchical binary logistic regressions were performed to examine the association between correlates and child and youth suicidality, and the interaction effects of these factors and school-age groups. Approximately 17.51% and 7.84% of secondary school respondents and 15.76% and 8.17% of primary school respondents reported suicidal ideation and attempt, respectively. Common correlates for suicidal ideation were depression, bullying, loneliness, self-compassion, and growth mindset, while those for suicide attempt were depression and bullying. Secondary school respondents with higher life satisfaction reported less suicidal ideation, while primary school respondents with higher self-control reported fewer suicide attempts. In conclusion, we recommended recognizing the factors of suicidal ideation and attempt in children and adolescents to tailor preventive strategies in a culturally sensitive manner.

A Pre-Adolescent and Adolescent Clinical Sample Study about Suicidal Ideation, Suicide Attempt, and Self-Harming

Suicide is the second cause of death among adolescents, and nonsuicidal self-injury (NSSI) is one of the main risk factors for suicidal behavior. However, the possible variables specifically associated with suicidal ideation and suicide attempt, as well as the psychopathological characteristics linked to the concomitant presence of suicidal ideation/attempt and NSSI are still under-investigated in youth. The current study aimed to address these issues in a sample of 174 young Italian inpatients (M_age = 14.3 years ± 1.93, 78.2% girls). Sociodemographic and clinical variables were assessed through psycho-diagnostic interviews and ad hoc questionnaires. A binomial logistic regression was performed to identify the predictors of suicidal ideation and suicide attempt. Then, Kruskal-Wallis tests were run to analyze the psychopathological differences between patients with suicidal ideation and suicide attempt considering the coexistence of NSSI. The results highlighted that previous access to child mental health services and general psychopathological problems significantly predicted suicidal ideation, while previous hospitalizations, borderline personality functioning, and affective disorders significantly predicted suicide attempt. In general, inpatients with also NSSI reported higher levels of internalizing, somatic and total problems, impulsiveness, alexithymia, and emotional dysregulation. The clinical implications of our findings in terms of primary and secondary preventive programs are discussed.

Admissions of Children and Adolescents With Deliberate Self-harm to Intensive Care During the SARS-CoV-2 Outbreak in Australia

IMPORTANCE

Identification of potential indirect outcomes associated with the COVID-19 pandemic in the pediatric population may be essential for understanding the challenges of the current global public health crisis for children and adolescents.

OBJECTIVE

To investigate whether the SARS-CoV-2 outbreak and subsequent effective public health measures in Australia were associated with an increase in admissions to intensive care units (ICUs) of children and adolescents with deliberate self-harm (DSH).

DESIGN, SETTING, AND PARTICIPANTS

This national, multicenter cohort study was conducted using the Australian data subset of the binational Australian and New Zealand Paediatric Intensive Care registry, a collaborative containing more than 200 000 medical records with continuous contributions from all 8 Australian specialist, university-affiliated pediatric ICUs, along with 1 combined neonatal-pediatric ICU and 14 general (adult) ICUs in Australia. The study period encompassed 6.5 years from January 1, 2015, to June 30, 2021. Patients aged 12 to 17 years were included. Data were analyzed from December 2021 through February 2022.

EXPOSURES

Any of the following admission diagnoses: ingestion of a drug, ingestion of a nondrug, hanging or strangulation, or self-injury.

MAIN OUTCOMES AND MEASURES

The primary outcome measure was the temporal trend for national incidence of DSH ICU admissions per 1 million children and adolescents aged 12 to 17 years in Australia.

RESULTS

A total of 813 children and adolescents aged 12 to 17 years admitted to ICUs with DSH were identified among 64 145 patients aged 0 to 17 years in the Australian subset of the registry during the study period. Median (IQR) age was 15.1 (14.3-15.8) years; there were 550 (67.7%) female patients, 261 (32.2%) male patients, and 2 (0.2%) patients with indeterminate sex. At the onset of the pandemic, monthly incidence of DSH ICU admissions per million children and adolescents increased from 7.2 admissions in March 2020 to a peak of 11.4 admissions by August 2020, constituting a significant break in the temporal trend (odds ratio of DSH ICU admissions on or after vs before March 2020, 4.84; 95% CI, 1.09 to 21.53; P = .04). This occurred while the rate of all-cause admissions to pediatric ICUs of children and adolescents of all ages (ie, ages 0-17 years) per 1 million children and adolescents decreased from a long-term monthly median (IQR) of 150.9 (138.1-159.8) admissions to 91.7 admissions in April 2020.

CONCLUSIONS AND RELEVANCE

This cohort study found that the coronavirus pandemic in Australia was associated with a significant increase in admissions of children and adolescents to intensive care with DSH.

Child suicides in Sweden, 2000-2018

Although child mortality is decreasing in Sweden, an increase in suicide rates has been previously observed among children and adolescents collectively. To increase knowledge about trends, demographics, and means in child suicides, data including all child (< 18 years) suicides in Sweden in 2000 through 2018 were retrieved from the Swedish National Board of Forensic Medicine. In all, a total of 416 child suicides were found in a 19-year period, accounting for an annual suicide rate of 1.1/100,000 child population. The number of suicides increased with 2.2% by each successive year during the study period (p < 0.001). The mean age in both sexes was 16 years; boys accounted for 55% and girls for 45% of all study cases. The majority of the children who died by suicide (96%) were teenagers (13-17 years old) and suicides in children younger than 10 years were uncommon. Suicide methods were 59% hanging, 20% lying/jumping in front of a moving object, 8% jumping from a height, 7% firearm injury, 4% poisoning, and 2% other methods. Sex differences were significant (p < 0.001) only for firearms being preferably used by boys. The vast majority of firearms used were licensed long-barreled weapons.Conclusion: The number of child suicides in Sweden is relatively low but increasing. Most of the children used a violent and highly lethal method. Prevention of premature mortality is an urgent concern with an emphasis on resolutely reducing the availability of suicide means. What is Known: • Suicide is a significant cause of death globally among children, bringing tragic consequences for young individuals, their family, and the entire society. • Suicide rates and distribution of suicide methods in children differ between countries and settings, but studies of time trends are scarce. What is New: • Increasing number of minors' suicides and the predominance of violent methods emphasize the importance of prevention strategies tailored for a child population. • Even in a setting of very restrictive firearm laws, firearm suicides in children must not be overlooked.

Notifications, hospitalizations and deaths from self-harm in children in Brazil's national health systems

There are virtually no statistics on childhood suicidal behavior globally. This setting can be partly explained by the social representation of joy in this early phase of life. This paper aims to analyze information on self-harm reports, hospitalizations, and deaths among children aged 5-9 years in Brazil to know its magnitude and distribution from 2006 to 2017, based on data from national health information systems. The results show 58 deaths of Brazilian children with intentional self-harm, primarily male, white, and nine years old. Hanging was the most commonly used mechanism for children to kill themselves. A total of 1,994 hospitalizations were recorded for suicide attempts in children in the period 2006-2017, with a predominance of males in all regions. Regarding notifications, most refer to children between 8 and 9 years of age, black and female, emphasizing self-poisoning. Evidence that any suicidal behavior in childhood is strongly associated with attempted or completed suicide in adolescence and adulthood is one of the main indications of the need to prevent this behavior in the first decade of life.

An Exploratory Cohort Study of the Association between the Level of Testosterone and Suicidal Ideation in Hospitalized Adolescent Females with Depression in China

BACKGROUND

To date, around 4 per 100,000 adolescents committed suicide within the 29 OECD countries. The suicidal behavior is related to psychological factors, genetics, neurobiology, and other biomarkers. The aim of this study was to examine risk factors for the development of suicidal ideation in adolescent females with depression, focusing on the relationship between different testosterone levels and suicidal ideation, in order to help develop strategies to intervene in suicidal behavior in female adolescents with depression.

METHOD

In this single-center prospective cohort study, we enrolled adolescent females with depression. We collected information on their baseline data, testosterone levels, symptom self-rating scale scores, suicidal ideation, non-suicidal self-injurious (NSSI) behaviours, and suicide attempts. We used multivariate logistic regression to identify risk factors for the development of suicidal ideation in adolescent females with depression.

RESULTS

A total of 113 hospitalized adolescent females were enrolled with a mean age of 13.5 (1.20). Among these patients, there were 86 (76.11%) subjects who suffered from suicidal ideation, 59 (52.21%) had NSSI and 23 (20.35%) had suicide attempt behavior. In the final model, higher level of testosterone (p=0.04) and higher age (p=0.02) were associated with the higher odds of having suicidal ideation.

CONCLUSION

In this exploratory cohort study, the emergence of suicidal ideation was common among adolescent females with depression. This study is consistent with the other studies. It shows that the age is a potential predictor for suicidal ideation in hospitalized adolescent females with depression.

Suicide ideation, suicide plan, and suicide attempt among left-behind children and adolescents: A systematic review and meta-analysis

OBJECTIVE

There are an increasing number of studies that discussed suicide ideation (SI), suicide plan (SP), and suicide attempt (SA) among left-behind children (LBC). However, the prevalence of these indicators of LBC has not been synthesized and the true correlation between these indicators and left-behind status remains unclear.

METHODS

Electronic databases were comprehensively searched, and eligible observational studies were selected to extract useful data. We pooled the rates and their 95% confidence intervals (95% CIs) to determine the prevalence of SI, SP, and SA among LBC. The odds ratios (ORs) and 95% CIs were calculated to reflect the association between left-behind status and risk of SI, SP, and SA.

RESULTS

Among LBC, the pooled prevalence was 18.7% (95% CI: 15.4-21.9) for SI, 6.4% (95% CI: 4.7-8.1) for SP, and 3.1% (95% CI: 2.6-3.6) for SA. Compared to non-LBC, LBC was at higher risk of SI (OR = 1.26), SP (OR = 1.20), and SA (OR = 1.14), but only the effect for SI achieved statistical significance.

CONCLUSION

Overall, the prevalence of SI, SP, and SA is common among LBC, and parental migration has a significant impact on the SI of LBC. Intervention plans and programs are urgently needed to prevent suicidality of this vulnerable group.

Triple taboo: considerations about suicide among children and adolescents

This article aims to understand the construction and repercussion of taboos involving suicides among children and adolescents, considering the discomfort, silence, and dread that the theme causes across society. Due to the recognition of a continuum of taboos (taboo of death < taboo of suicide < taboo of child suicide), the authors present, as an attempt to address this issue, the concept of a triple taboo, recognizing the incommensurability of self-inflicted deaths that have children and adolescents as protagonists. Developed from a qualitative study with paediatricians during their medical residence, this paper serves as a call to professionals who assist children and adolescents in the country. Paediatric training needs to recognise these taboos and the dimensions of suicidal behaviour as a manifestation of violence and as a threat to mental health. Their identification is a critical and urgent element in contemporary children and adolescents' care.

SITUAÇÕES DE SUICÍDIO: ATUAÇÃO DO PSICÓLOGO JUNTO A PAIS ENLUTADOS

Com o tema da clínica psicológica em situações de suicídio, mais especificamente o da atuação do psicólogo junto a pais enlutados, pretendemos defender que a formação em psicologia pode favorecer conhecimentos e experiências diferenciados de outros saberes. Para alcançarmos nosso objetivo, analisamos publicações, reportagens e entrevistas com pais afetados pelo acontecimento. Assim, temas como a morte, o luto, a saudade e a clínica psicológica foram desenvolvidas mediante uma revisão narrativa da literatura de publicações científicas.  Em conclusão, pretendemos defender a possibilidade de uma prática psicológica para além dos manuais, os quais prescrevem ao profissional os comportamentos a serem expressos nas situações referidas. Ir além dos manuais significa poder acompanhar a experiência de luto sem jargões ou simbolismos meramente técnicos, ou seja, poder, na própria experiência de luto, em uma atitude serena e paciente, tal como desenvolvida por Kierkegaard e Heidegger, permanecer junto à dor ou ao sofrimento, sustentando a possibilidade de um momento epifânico, como nos mostra Clarice Lispector.

CLINICAL AND EPIDEMIOLOGICAL ANALYSIS OF SUICIDE ATTEMPTS IN CHILDREN ASSISTED BY A POISON CONTROL CENTER

Objective:

To assess suicide attempts in children seeking care at a Poison Control Center.

Methods:

Cross-sectional study with children (<12 years old) that attempted suicide and were cared at the Poison Control Center in Londrina, Paraná, Southern Brazil, from April 1985 to December 2018.

Results:

We identified 59 children, most of them females (74.6%), who used only one product (77.9%). Among the products involved, medications were the most important ones (88.1%). Neurological/psychiatric/muscular manifestations (61.0%) were the main symptoms presented. The main reason identified for the suicide attempt was conflicts with family and/or friends (27.1%). Suicide attempts were more frequent in 2001-2003 and 2016-2018.

Conclusions:

Suicide attempts occurred mainly in female children with a single agent (mainly medications), and the main reason was family conflicts..

Vítimas de bullying, sintomas depressivos, ansiedade, estresse e ideação suicida em adolescentes

Objetivou-se verificar a correlação entre ser vítima de bullying, ter sintomas depressivos, de ansiedade, de estresse e ideação suicida em adolescentes. Além disso, foi identificado se havia diferença nos construtos investigados, por gênero e idade. Estudo quantitativo transversal, do qual participaram 117 adolescentes. Utilizaram-se os instrumentos: questionário sociodemográfico, Escala Califórnia de Vitimização do Bullying, Escala de Depressão, Ansiedade e Estresse, e Escala Beck de Suicídio. As análises foram realizadas por meio de estatística descritiva, correlação de Spearman e teste U de MannWhitney. Os resultados indicam que 48,71 % da amostra apresenta ideação suicida. Houve correlação positiva entre ser vítima de bullying e ter sintomas depressivos, ansiedade e estresse, e ser vítima e ter ideação suicida. As meninas apresentam mais sintomas de estresse do que os meninos, e adolescentes mais novos são mais vítimas de bullying do que os mais velhos. Destaca-se, assim, a relevância da discussão desse tema, tanto nas escolas quanto nas famílias, a fim de diminuir o sofrimento psíquico das vítimas.

Self-injurious behavior and related mortality in children under 10 years of age: a retrospective health record study in Brazil

OBJECTIVE

To describe and analyze data on self-injurious behavior (SIB) and related mortality in children under 10 years old in Brazil.

METHODS

A descriptive study was performed using secondary public health care data extracted from the Hospital Information System (Sistema de Informações Hospitalares, SIH) and Mortality Information System (Sistema de Informações sobre Mortalidade, SIM) in Brazil. The databases are available for online access at http://datasus.saude.gov.br/.

RESULTS

In Brazil, according to SIH data, 11,312 hospitalizations of patients under 10 years of age were recorded from 1998 to 2018 as resulting from SIB (ICD-10 X60-X84 codes). Of these, 65 resulted in death. According to the SIM, from 1996 to 2016, 91 deaths related to SIB were recorded, 81 (89%) in children aged 5 to 9 years, nine (9.9%) in children aged 1 to 4 years, and one (1.1%) in a child below 1 year of age.

CONCLUSION

These results highlight the relevance of creating measures to better understand SIB and related mortality in this age group. They also reveal the vulnerability of children in Brazil and warrant further studies to address these issues.

[Mortality from suicide in indigenous children in Brazil]

This study aimed to describe the characteristics, distribution, and mortality rates from suicide in indigenous children in Brazil compared to non-indigenous children. This descriptive study covered the years from 2010 to 2014, using national databases. The study collected deaths in individuals 10 to 14 years of age whose underlying cause was "inentional self-inflicted injury". Hanging was the most frequently used means in both indigenous and non-indigenous children, although it was more frequent in the former. Among indigenous children, suicides in hospitals or other healthcare establishments were less common than in non-indigenous. Approximately three-fourths of suicides in indigenous children occurred in just 17 municipalities. The mortality rate from suicide among indigenous children was 11.0/100,000 (8.4-14.3), or 18.5 times higher (10.9-31.6) than in non-indigenous, which was 0.6/100,000 (0.5-0.6), with no differences between boys and girls. This study showed for the first time on a national scale the specific characteristics of suicide in indigenous children, with high rates, and also identified priority areas for interventions.
