A Viewpoint on the Rising Trend of Couple Suicide in India.

It is extremely disturbing that in contemporary times, the cases of couple suicide is the matter of grave concern in India. It is observed that couples are committing suicide together in Indian society due to various social circumstances. The present study examines the nature of couple suicide and its causes using egoistic approach of suicide. The data have been collected from leading newspapers of India from 1st January 2023 to 15th May 2024 using systematic content analysis. The present research has identified that love affair is the cause of suicide in most cases of couple suicide. The study also revealed that about 50.59% of couples who are in the age group of 16-25 years committed suicide together due to love affairs. Additionally, the researchers have observed from egoistic point of view that socio-economic changes have unexpectedly affected the social conditions which has promoted the tendency of suicide in couples.

Mortality trends in suicide among pediatric and adolescent patients aged 15–24 years in Mississippi, 2012–2022

AbstractDue to the lack of studies examining suicide trends and its implications on pediatric populations, this study aimed to address the gap in research and to identify the magnitude and the impact of suicide by exploring trends in suicide among Mississippians from 2012 to 2022. The study uses data from the Mississippi Statistically Automated Health Resource System, which is an online database with data collected from vital statistics. Joinpoint regression models were used to calculate annual percentage change (APC) and average annual percentage change (AAPC) as an indicator of trends. The overall age‐adjusted suicide rate increased from 9.4 deaths per 100,000 in 2012 to 10.8 deaths per 100,000 in 2022 for pediatric and adolescent patients aged 15–24 years (14.9% increase). There are upward trends for females (AAPC, 6.33%, 95% CI, −0.82%–16.82%), Blacks (AAPC, 7.72%, 95% CI, 2.19%–16.47%), and other races (AAPC, 7.59%, 95% CI, −0.83%–21.47%). Males had a downward trend from 2015 to 2022 (APC, −1.46%, 95 CI, −14.05%–1.35%). Whites also had a downward trend from 2017 to 2022 (APC, 4.74%, 95% CI, −15.42% to −0.96%). This study identified an overall increase in suicide. However, trends varied by gender, race, and age. Based on the findings, Mississippi needs more initiatives aimed toward equitable prevention of suicide among youth and the implementation of gun control policies. By implementing these measures, Mississippi could tremendously benefit and improve mental health outcomes and reduce suicide within the state.

Considering Developmental Phenotypes of Suicidality for Young Black Children

ABSTRACTSuicide is currently the 5th leading cause of death among children aged 5–11, a rate that has more than tripled in the last decade, and one that has increased significantly more among Black compared to White children. Specifying early childhood phenotypes of suicidality is critical for prevention of suicidal behavior. Such phenotypes need to be culturally relevant and rigorously tested in Black youth to yield data that will inform prevention science. We used the Interpersonal Theory of Suicide, to guide both the development of a theoretical model and a research protocol to conduct a study on suicidality in young Black children. The model was informed by an ecological adaptation which considers the context of structural, systemic, and interpersonal racism as critical for conceptualizing suicidal risk and identifying factors that reduce the likelihood of suicidal ideation and behaviors among Black youth. Developmental adaptations of IPTS components were based on existing research supporting associations between theoretically similar constructs and early childhood depression and/or later suicidality. Model components include loneliness and lack of family connectedness, low self‐worth and hopelessness, and impulsivity. The components are measured via questionnaires and reactivity to behavioral probes as measured by facial emotion, heart rate variability, and self‐reported mood. Risk and protective factors include exposure to racism and discrimination and racial identity and socialization, respectively. An accelerated, longitudinal design, enrolling 5–9‐year‐old children for 6 repeated assessments over 45 months will allow us to test stability from early childhood to early adolescence. Conducting robust tests of early risk and stability of suicidality in the context of culturally relevant risk factors (e.g., racism) and protective factors (e.g., racial socialization and identity) will contribute to efforts to reverse recent trends in Black youth suicide.

Suicides and Overdoses at Work: Census of Fatal Occupational Injuries, 2011-2022

IntroductionThe worsening life expectancy of middle-aged white Americans due to suicides and substance overdoses has been hypothesized to be caused by various societal conditions. Work is a social determinant of health, but its role in this demographic shift has not been examined. This article describes the characteristics and trends of suicides and overdose fatalities occurring in U.S. workplaces among all workers between 2011 and 2022. MethodsData originated from the Census of Fatal Occupational Injury database. Fatality rates were calculated using the Current Population Survey. Fatality rates were calculated and compared among demographic and occupational groups. Annual rates were modeled with a first order auto-regressive linear regression to account for serial correlation. Analyses were conducted in 2023-2024. ResultsBetween 2011 and 2022, the rate of workplace overdose fatality rates increased from 0.05 per 100,000 workers to 0.33 - an increase of 560%. Workplace suicide rates were relatively stable (0.19 per 100,000 to 0.17). Most industries and occupations experienced significant increases in workplace overdose rates and non-significant decreases in workplace suicide rates. The largest workplace overdose rates occurred in the Transportation & Warehousing industry (0.47, 95% CI=0.27-0.67) and Farming, Fishing, & Forestry occupations (0.68, 95% CI=0.27-1.08). ConclusionsFatal workplace suicides and substance overdoses have different trends and impact industries, occupations, and demographic groups differently. The rise in workplace overdoses deserve immediate attention.

The annual trend of suicide rates from 2010 to 2021 in patients with cannabis use disorder – a national registry study

Abstract Purpose The temporal trend of suicide in patients with cannabis use disorder (CUD) is important to investigate, considering the recent increases in THC concentration in cannabis products. This study describes the annual suicide rates in patients with CUD from 2010 to 2021. To investigate if any change in suicide rate was specific to CUD, we compared these suicide rates with corresponding data for patients with alcohol use disorders (AUD) and other substance use disorders (SUDs). Method The study used a time series design. We used a national registry linkage between the Norwegian Cause of Death Registry and the Norwegian Patient Registry from 2010 to 2021, including patients with CUD (ICD-10 code F12), AUD (F10), or other SUDs (F11; F13-F16; F18-F19) who died by suicide, supplemented with the total number of patients treated with specific disorders to estimate the suicide rates. The trend was analyzed by comparing the annual suicide rate to 2010 and using Poisson regression, adjusting for gender, age, and mental disorders. Results We found increased annual incidence rate ratios for patients with CUD in 2018 (IRR = 2.14 (95% CI 1.14–3.99)) and onwards and an increasing time trend over the study period (IRR = 1.08 (1.05–1.12)). No increases in trends were found for AUD or other SUDs. The time trend for CUD was attenuated when adjusting for depressive or anxiety disorders (aIRR = 1.00 (0.92–1.08)) or other SUDs (aIRR = 0.96 (0.87–1.06)). Conclusions Increasing suicide rates were found in patients with CUD. Comorbid anxiety and depression or other SUDs, but not other mental disorders, could partly explain these results.

Trends and gender differentials in age-specific suicide mortality, 2004-2020, Cyprus

Abstract Background Cyprus is rarely included in international studies of suicide trends and the only published national data is two decades old. In the context of the first National Strategy for Mental Health, this study assessed suicide trends in 2004-2020, spanning the 2008 global and 2012-2013 Cyprus financial recessions, but falling short of the COVID-19 pandemic due to delays in recording. Methods Suicide deaths were obtained from the Mortality Registry (ICD-10, including “undetermined”). Directly standardized rates were calculated for four gender/age groups. Annual change was estimated in Poisson regression models with interaction terms to assess differential trends over time periods. Results There were 560 deaths (4-times more in men, >80% classified as ‘violent’ in both genders). In men, the suicide rate doubled from 4-5 to 9-10 per 100000, with most of the increase prior to 2012, representing 9% annual change (Rate Ratio 1.09, 95% CI 1.03, 1.15; p = 0.002). From 2013, the trend reversed (effect modification p-value < 0.001) with 4% annual decrease (95% CI -9%, 1%). Declines were not uniform across age-groups; rates in males aged 45-64 continued to rise, surpassing the previously high rate in males 25-44. In women, rates presented a declining trajectory from 4-5 per 100000 to 2-3 over this period, widening the gender differential. M-to-F ratio was 5.33 (95% CI 3.46, 8.19) in 2017-2020 compared to 2.73 (1.88, 3.95) in 2004-2008. A shift to violent methods was observed, with hanging now ranking as most common in both females (1 in 3) and males (1 in 2). Conclusions While relatively lower compared to other European countries, the gender differential in suicide mortality has widened in Cyprus, with steep rises in all male age-groups up to 2012 and continuing rises in males 45-64, but declines in female rates over the same period. Further analysis of trends in relation to unemployment and other socio-economic indicators is warranted as well as continuous monitoring of trends. Key messages • After steep rises in suicide across all male age-groups up to 2012, against a declining trajectory in female rates, rates in males 45-64 continued to rise, further widening the gender differential. • The age profiling and shift towards more violent methods in both genders should inform the first National Strategy for Mental Health, while continuous monitoring of trends is warranted.

Nationwide trends in the suicide mortality among the disabled in Korea from 2006 to 2017

Abstract Aims The disabled are one of the priority populations at risk of suicide, but there has been no study of the factors influencing suicide mortality among the disabled in South Korea. Methods To analyze age-standardized suicide mortality (ICD-10 Codes, X60-84) for each year according to the presence, severity and type of disability, we linked three population datasets (National Health Insurance Claims Database, Disability Registry, and Deaths by Cause). Our dataset covers the entire population of South Korea, extended over a 12-year period from 2006 to 2017. The analyses were stratified by sex, and hazard ratios for suicide were determined by multivariate logistic regression after adjustment for socio-demographic and clinical variables. Results The suicide rate among the disabled was 2.24 times higher than among the non-disabled in 2017. The highest suicide rates were observed among intellectual or mental disabled, and severe disabled. In the disabled group, suicide rates were higher among those with medical benefits, older age (over 70 years), and depressive disorders in both male and female. Conclusions Although the disabled people’s suicide is often seen as an individual problem, it actually affects their families, communities and society. Therefore, government must strive to emphasize the broad view of the disabled population - not just the health of individuals, and track suicide trends and identifying risk and protective factors for suicidal behavior. From this information, suicide prevention strategies for the disabled people should be evaluated to identify the most effective interventions. Financial support: This research was supported by the Basic Science Research Program through the National Research Foundation of Korea funded by the Ministry of Education (No. 2022R1I1A3070074, and 2022R1I1A1A01068449), and a grant of Patient-Centered Clinical Research Coordinating Center funded by the Ministry of Health & Welfare, Republic of Korea (No. HC23C016500). Key messages • The suicide rate among the disabled was 2.24 times higher than among the non-disabled in 2017. • In the disabled group, suicide rates were higher among those with medical benefits, older age (over 70 years), and depressive disorders in both male and female.

Chronic Corticosterone Administration-Induced Mood Disorders in Laboratory Rodents: Features, Mechanisms, and Research Perspectives

Mood disorders mainly affect the patient’s daily life, lead to suffering and disability, increase the incidence rate of many medical illnesses, and even cause a trend of suicide. The glucocorticoid (GC)-mediated hypothalamus–pituitary–adrenal (HPA) negative feedback regulation plays a key role in neuropsychiatric disorders. The balance of the mineralocorticoid receptor (MR)/glucocorticoid receptor (GR) level contributes to maintaining the homeostasis of the neuroendocrine system. Consistently, a chronic excess of GC can also lead to HPA axis dysfunction, triggering anxiety, depression, memory loss, and cognitive impairment. The animal model induced by chronic corticosterone (CORT) administration has been widely adopted because of its simple replication and strong stability. This review summarizes the behavioral changes and underlying mechanisms of chronic CORT administration-induced animal models, including neuroinflammatory response, pyroptosis, oxidative stress, neuroplasticity, and apoptosis. Notably, CORT administration at different doses and cycles can destroy the balance of the MR/GR ratio to make dose-dependent effects of CORT on the central nervous system (CNS). This work aims to offer an overview of the topic and recommendations for future cognitive function research.

International trends in male youth suicide and suicidal behaviour.

Suicide and suicidal behaviour strongly contribute to overall male youth mortality. An understanding of worldwide data contextualises suicide and suicidal behaviour in young men within any given country. Members and colleagues of the World Federation of Societies of Biological Psychiatry's Task Force on Men's Mental Health review the relevant data from several regions of the world. The review identifies notable findings across regions of relevance to researchers, policymakers, and clinicians. Male suicide and suicidal behaviour in adolescence and emerging adulthood within North America, Latin America and the Caribbean, Europe, the Mediterranean and the Middle East, Continental Africa, South Asia, East Asia, China, and Oceania share similarities as well as significant points of divergence. International data provide an opportunity to obtain a superior understanding of suicide and suicidal behaviour amongst young men.

Trajectory of suicide among Indian children and adolescents: a pooled analysis of national data from 1995 to 2021

BackgroundSuicide is a major public health concern in India especially among children and adolescents. The yearly national statistics show a concerning trend of rising suicide deaths in these age groups.MethodsThe present study, taking 26 years of national data from the National Crime Record Bureau during 1995–2021, examined the trend, patterns, means, and modes of children/adolescent suicides in India. We also undertook a time series analysis by using ARIMA (0,2,1) model to forecast the expected suicide rate for the next one decade.ResultsA rising trend of suicide rate among children and adolescents was observed in India over the last 26 years. The forecast indicates a continuance of rising suicide cases for the upcoming decade in India. A substantially different trend of suicide rate was observed among early and late adolescents indicating significantly high vulnerability of late adolescents. Among children /adolescents, the most common causes of suicide were family problems, academic failure, illness, and unemployment. Illness has emerged as one of the leading causes of suicide, with a significant rise over time. Poverty and unemployment were also found as the important contributors with a steadily increasing trend of suicide among children and adolescents facing these problems in recent years.ConclusionThe study provides important analysis and information on suicide among children/adolescents in India, by providing useful insights for parents, teachers, policymakers, healthcare practitioners, and stakeholders aiming to prevent and control children and adolescent suicide and boost mental health. The study also provides important leads on risk factors with a forecast of suicide trends for the next 10 years.

Associations between a Brazilian suicide awareness campaign and suicide trends from 2000 to 2019: Joinpoint and regression discontinuity analysis

BackgroundSuicide is a global health concern whose rates are soaring in many low-and-middle-income countries. Public awareness campaigns have been implemented in Brazil; however, their impact is uncertain. MethodsThis was an ecological study using population data from DATA-SUS, a Brazilian official notification system, selecting only deaths that were voluntarily self-inflicted (CID-10 × 60-X84). We analyzed all available data from 2000 to 2019 to assess trends before and after the national Yellow September (YS) campaign started in 2015. Differences in trends were assessed by Joinpoint Analysis (JA) and Regression Discontinuity Analysis (RDD), unadjusted and adjusted for economic factors. ResultsOverall, there was a progressive increase in the rate of relative (per 100,000 inhabitants) number of suicides over time between 2000 and 2019 (57 % increase). The JA detected a change in the slope of the curve representing an acceleration in suicides starting in the year 2015. Adjusted RDD revealed the year that Yellow September started significantly change the slope of the association between time and rates of suicide (pinteraction < 0.01), and marginal analysis detected the coefficient increased from 0.07 (95%CI 0.04–0.10) to 0.27 (95%CI -0.07-0.60) suicides/year per 100,000 inhabitants. LimitationsThe ecological nature of the manuscript compromises causational implications. ConclusionsWe found an increase in suicidal trends in Brazil, against the global trend that coincides with the beginning of a large national awareness campaign. Although we cannot attribute causality, our results reinforce the need of further studies to better understand the role of awareness campaigns in suicide reduction interventions, including potential unintended effects.

Suicide in the USA: A Decadal Study From the 1930s to the 2020s.

This study provides a decadal analysis of national suicide data over 90 years, offering a comprehensive view of long-term trends and current levels in the United States. We analyzed mean decadal suicide numbers, rates, and confidence intervals from the 1930s to the early 2020s across demographic categories including sex, race, and age. Our findings reveal that suicide rates in the 2020s are the highest since the 1930s. The data indicate significant variations across groups; the 2020s show the highest suicide rates for both Whites and Nonwhites, and individuals under 44years of age. Conversely, men's suicide rates were slightly lower than those in the 1930s, whereas rates for women and older adults peaked during the 1930s. The results underscore the need for ongoing surveillance of suicide trends and proactive suicide prevention measures by governmental and other relevant organizations.

Autism, youth suicide, and psychedelics: A review of the 21st century evidence.

The concurrent rise in the prevalence of autism and youth suicide has drawn public health and professional attention. The renaissance of psychedelics in psychiatry occurred in the early 21st century and may suggest a hope for the therapeutic effect of psychedelics in autism and suicide. The psychedelics' molecular entities are the compounds that modulate the serotoninergic and glutamatergic systems, which play a crucial role in the pathomechanisms underlying autism and suicide. This systematic review comprehensively discussed the prevalence trends of autism and youth suicide globally and in Taiwan and discussed an association between autism and suicidality based on the 21st century clinical and preclinical literature. Furthermore, this review proposed a possible neurobiological connection between autism, suicide, and psychedelics. Finally, this review discussed the potential therapeutic applications of psychedelics in autism and youth suicide.

RETRACTED: National trends of suicidality 1999–2020 among Asian American Pacific Islander young adults across sex

This study analyzes 21 years of suicide trend among Asian American Pacific Islander (AAPI) young adults aged 18–25. Analyzing NCHS data (1999–2020) through the Joinpoint Regression, we examined temporal trends of suicide death across sexes and identified trend shifts. Findings indicate a significant and steady increasing trend in AAPI female suicides from 1999 to 2020. Alarmingly, AAPI males displayed a significant and sharp increasing trend of suicide from 2008 onwards. It is important to consider other risk factors of suicide, including cultural factors and gendered racial experiences, to understand the context of AAPI young adults’ suicide patterns.

Global public concern of childhood and adolescence suicide: a new perspective and new strategies for suicide prevention in the post-pandemic era.

Suicide is the second leading cause of death in young people worldwide and is responsible for about 52,000 deaths annually in children and adolescents aged 5-19years. Familial, social, psychological, and behavioral factors play important roles in suicide risk. As traumatic events such as the COVID-19 pandemic may contribute to suicidal behaviors in young people, there is a need to understand the current status of suicide in adolescents, including its epidemiology, associated factors, the influence of the pandemic, and management initiatives. We investigated global and regional suicide mortality rates among children and adolescents aged 5-19years using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The suicide mortality rates from 1990 to 2019 were examined in 204 countries and territories across six World Health Organization (WHO) regions. Additionally, we utilized electronic databases, including PubMed/MEDLINE and Scopus, and employed various combinations of terms such as "suicide", "adolescents", "youth", "children", "risk factors", "COVID-19 pandemic", "prevention", and "intervention" to provide a narrative review on suicide within the pediatric population in the post-pandemic era. Despite the decreasing trend in the global suicide mortality rate from 1990 to 2019, it remains high. The mortality rates from suicide by firearms or any other specified means were both greater in males. Additionally, Southeast Asia had the highest suicide rate among the six WHO regions. The COVID-19 pandemic seems to contribute to suicide risk in young people; thus, there is still a strong need to revisit appropriate management for suicidal children and adolescents during the pandemic. The current narrative review integrates up-to-date knowledge on suicide epidemiology and the effects of the COVID-19 pandemic, risk factors, and intervention strategies. Although numerous studies have characterized trends in suicide among young people during the pre-pandemic era, further studies are required to investigate suicide during the pandemic and new strategies for suicide prevention in the post-pandemic era. It is necessary to identify effective prevention strategies targeting young people, particularly those at high risk, and successful treatment for individuals already manifesting suicidal behaviors. Care for suicidal children and adolescents should be improved with parental, school, community, and clinical involvement.

Spatio-temporal patterns of excess mortality from non-COVID causes of death in the United States, march-December 2020.

Objectives To estimate the burden of excess mortality from 17 underlying causes of death between March-December 2020 in the United States, and to compare trends in excess deaths from non-COVID causes vs. from COVID-19. Methods Using time series models, we estimated monthly counts of all-cause and cause-specific excess deaths. We stratified by geographic region and compared temporal trends in excess deaths from non-COVID causes to trends in deaths attributed to COVID-19. Results Of approximately 500,000 excess deaths, 70% were attributed to COVID-19. We observed increases in several underlying causes of death, ranging from a 3% increase in kidney disease deaths to a 24% increase in homicides, as well as decreases in deaths from cancer (-0.3%), influenza and pneumonia (-2%), chronic lower respiratory disease (-3%), and suicide (-7%). Trends in excess deaths from cardiovascular disease, diabetes, and Alzheimer's disease closely mirrored trends in deaths from COVID-19. Trends in excess liver disease, homicide, suicide, and motor vehicle accident deaths were negatively correlated with trends in deaths from COVID-19. There was wide regional variation in excess death rates for some causes of death, including a disproportionate increase in homicide and motor vehicle accident deaths in the Great Lakes, and a sustained reduction in cancer deaths in the Mideast and New England. Conclusions Increases in cardiovascular disease, diabetes, and Alzheimer's disease deaths from March-December 2020 likely reflect healthcare system disruptions or acute complications of COVID-19. Excess deaths from homicide and liver disease are more likely to reflect social and economic effects of the emerging pandemic, or other separate causes.

National Trends in Suicide Among Asian American or Pacific Islander Youth

National Trends in Suicide Among Asian American or Pacific Islander Youth

Trends in the impact of suicide compared to other external causes of death: From 1995 to 2020

BackgroundSuicide is one of the world's greatest public health problems. More than 700,000 people lose their lives to suicide every year. While funding for mental health waits to be increased, thousands of suicides occur every day. Material and methodsThis study aims to quantify the global impact of suicide compared to other external causes of death in terms of years of potential life lost (YPLL), and how this will change between 1995 and 2020. Our source of information is the World Health Organization (WHO) mortality database. We then use YPLL, a standard measure of premature mortality and burden of disease that brings precision to the assessment of the impact of different causes of death. This, combined with the compound annual growth rate (CAGR) as a way of expressing increase, gives us a better understanding of the real situation and trends of suicide compared to other external causes of death in different countries worldwide. ResultsBased on the available sources of information and the selection criteria, we obtained a sample of 69 countries. The CAGR for all causes per capita decreased over the observed period in 65 countries, and it increases in 4 countries. In contrast, the CAGR specifically for suicide decreased in 49 countries, while an increase was observed in 20 countries. ConclusionsPrevention of most external causes of mortality shows promising data in most countries. However, this is not the case for suicide. Thus, YPLL due to suicide have decreased to a comparatively lesser extent and have even increased in some countries, a very worrying situation that poses many clinical and epidemiological challenges.

Sex Differences in the Global Prevalence of Nonsuicidal Self-Injury in Adolescents

Nonsuicidal self-injury (NSSI) is a strong predictor of suicide attempts. The prevalence of NSSI has been increasing among female adolescents in North America and Europe, but less is known about trends in other geographical regions. To examine sex differences in the prevalence of NSSI among adolescents within and between geographical regions. MEDLINE and PsycINFO were searched using the keywords adolescents, self-injury, sex factors, and synonyms for articles published in English between January 1, 2000, and May 10, 2022. Studies were included if they presented original data (any study design), included adolescents aged 10 to 19 years, reported results stratified by sex, and explicitly defined self-injury as behaviors occurring without suicidal intent. This meta-analysis was registered with PROSPERO and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Articles were assessed for quality by 2 independent coders (F.M. and J.A.). A random-effects model was used to calculate prevalence. Data were analyzed from July 2022 to April 2023. The prevalence of NSSI in male and female adolescents within and between regions was the main outcome. Odds ratios (OR) with 95% CIs were calculated for community samples. Eight hundred and two studies were screened, and 38 were included (266 491 participants). Across 17 countries, the pooled prevalence of NSSI was 17.7% (female:male OR, 1.60; 95% CI, 1.29-1.98). NSSI was twice as prevalent among female adolescents compared with male adolescents in North America (OR, 2.49; 95% CI, 2.16-2.86) and Europe (OR, 2.08; 95% CI, 1.69-2.58), but not in Asia (OR, 1.00; 95% CI, 0.71-1.41). In this meta-analysis of sex differences in global prevalence of NSSI, the female predominance of NSSI observed among adolescents in North America and Europe aligned with rising rates of suicide in these populations. The comparable prevalence of NSSI among male and female adolescents in Asia also aligned with the lower male-to-female suicide ratio compared with other countries. More research is needed to characterize regional (and potentially cultural) sex differences among adolescents with NSSI to prevent and treat the behavior and to understand the possible interplay with corresponding regional trends in suicide.

The importance of methodological vigilance: Reevaluating suicide trends in Japan post‐2022

The importance of methodological vigilance: Reevaluating suicide trends in Japan post‐2022
