Suicide before and during the COVID-19 Pandemic: A Systematic Review with Meta-Analysis

Depression Self-Care Apps' Characteristics and Applicability to Older Adults: Systematic Assessment

BACKGROUND

Depression affects 32% of older adults. Loneliness and social isolation are common risk factors for depression in older adults. Mobile apps can connect users and are also effective in depression management in the general population. However, older adults have specific needs in terms of the content of depression self-care interventions and their accessibility. It remains unknown whether existing apps for depression self-care are applicable to older adults.

OBJECTIVE

The initial aim of this assessment was to systematically identify interactive depression self-care apps specifically designed for older adults. As we did not find any, we assessed the applicability of existing depression self-care apps to the needs of older adult users.

METHODS

Using an established app assessment methodology, we searched for Android and iOS interactive mental health apps providing self-care for depression in English and Chinese in the 42Matters database, Chinese Android app stores, and the first 10 pages of Google and Baidu. We developed an assessment rubric based on extensive revision of the literature. The rubric consisted of the following sections: general characteristics of the apps (eg, developer, platform, and category), app content (eg, epidemiology and risk factors of depression in older adults, techniques to improve mood and well-being), and technical aspects (eg, accessibility, privacy and confidentiality, and engagement).

RESULTS

We identified 23 apps (n=19, 82.6%, English and n=4, 17.4%, Chinese apps), with 5 (21.7%) iOS-only apps, 3 (13%) Android-only apps, and 15 (65.2%) apps on both platforms. None specifically targeted older adults with depression. All apps were designed by commercial companies and were free to download. Most of the apps incorporated cognitive behavior therapy, mood monitoring, or journaling. All but 3 (13%) apps had a privacy and confidentiality policy. In addition, 14 (60.9%) apps covered depression risk factors in older adults, and 3 (13%) apps delivered information about depression epidemiology in older adults via a chatbot. Furthermore, 17 (73.9%) apps mentioned other topics relevant to older adults, such as pain management, grief, loneliness, and social isolation. Around 30% (n=7) of the apps were supported by an online forum. Common accessibility issues included a lack of adaptations for users with visual or hearing impairments and incompatibility with larger font sizes in the phone settings.

CONCLUSIONS

There are no depression apps developed specifically for older adults. Available mobile apps have limited applicability to older adults in terms of their clinical and technical features. Depression self-care apps should aim to incorporate content relevant to older adults, such as grief and loss; include online communities; and improve accessibility to adapt to potential health impairments in older adults.

Suicide in Italy: Epidemiological Trends, Contributing Factors, and the Forensic Pathologist's Role in Prevention and Investigation

Suicide in Italy represents a serious public health problem, with significant data highlighting the urgency for prevention interventions. According to the epidemiological data, in the two-year period 2020-2021, 7422 suicides were recorded, representing an increase compared to previous years. Suicide is the most extreme self-harm. The contributing factors that surround this event are multiple, typically in conditions of serious distress or psychological distress, in particular in people suffering from serious psychiatric and/or mental disorders, such as depression. The role of the forensic pathologist in the context of suicide is crucial for ascertaining the contributing factors of death and for understanding the circumstances that lead to the suicidal act. Forensic medicine plays a crucial role in the analysis and understanding of suicides, addressing both the legal and medical implications. The aim of this study was to accurately describe the phenomenon of suicide in Italy. The accuracy of the review was very important in paying attention to the large difference in how the phenomenon manifests itself in the male population compared to the female population. The different ages at which suicide is committed were highlighted. The geographical difference between the North and the South and between the more urbanized areas compared to the rural areas where suicide is committed was analyzed. This scientific work also aimed to explore how forensic pathologists contribute to the resolution of complex forensic investigations. Psychological autopsy is an investigative method used primarily in cases of violent or questionable death, with the aim of understanding the psychological and social circumstances that led to an individual's death. This practice is distinct from forensic autopsy, which focuses on the physical analysis of the body to determine the cause of death. The role of forensic pathologists in investigating suicide cases is crucial, as they not only determine the cause of death but also analyze the psychological implications that may have led to the extreme act. The main objective of a forensic pathologist in these cases is to gather and interpret evidence that can help understand the psychological and social context that influenced the decision to commit suicide, identifying any warning signs and underlying motivations and factors that may have contributed to the suicide. This approach provides valuable information for prevention, enhancing the understanding of the psychological mechanisms behind suicide and supporting targeted interventions in the future. The manuscripts also have an explanatory purpose and may have a therapeutic role in helping surviving relatives understand suicide. Knowledge of the messages contained in suicide notes could be useful for suicide prevention programs.

The Trend in Suicide Risk Among People with HIV Before, During, and After the COVID-19 Pandemic Lockdown

Suicide Risk (SR) and the COVID-19 pandemic affected People with HIV (PWH) disproportionately in comparison with the general population, but little information on SR during and after the COVID-19 lockdown on the Latino PWH has been described, therefore, this study aimed to describe SR in PWH attended the HIV clinic before (2018-2019), during (2020), and after (2021-2022) the COVID-19 lockdown, the trend of SR, and the factors associated. Three standardized questions from the "Columbia-Suicide Severity Rating Scale" (C-SSRS) were routinely applied as screening for suicide risk to all PWH attending their clinical visits during 2018-2022. We estimated suicidality risk and rate. We compared sociodemographic characteristics in those with and without SR. We evaluated the potential association of SR with the calendar year before, during, and after the COVID-19 lockdown using a mixed-effects logistic regression. A total of 2330 patients were seen during the study period; 2157 (93%) were evaluated for suicidality at least once, of those, 75 (3.5%) had SR. Those with SR compared with non-SR were more frequently women (20% vs 10%) and with a heterosexual HIV transmission route (29% vs 23%). SR rates per 1000 patients-day among those evaluated were 0.03 in 2018, 0.25 in 2019, 3.16 in 2020, 7.0 in 2021 and 11.98 in 2022. Throughout the model, independently of covariables, a significant increase in the OR of SR was observed in these years compared to 2018: 1.07 in 2019; 2.74 in 2021; and 4.82 in 2022, except in 2020, OR = 0.18.

Investigating Suicide Risk Factors Among Appalachian West Virginian Adults

Introduction

Suicide rates in the United States have increased over the past two decades, with rural areas, particularly the Appalachian Region, facing unique challenges that elevate suicide risk. These include economic hardships, social isolation, and limited access to mental health services.

Purpose

This study addresses critical gaps in understanding lifetime suicide risk in West Virginia (WV), a predominantly rural state entirely within the Appalachian Region. By identifying the factors driving urban-rural differences in suicide risk, this research seeks to inform interventions tailored to the state's distinct needs and provide insights applicable to the broader Appalachian.

Region Methods

Using 2021 Mountain State Assessment of Trends in Community Health (MATCH) survey data, we examined socioeconomic and related factors associated with lifetime suicide risk in WV, measured by the first item of the Suicide Behaviors Questionnaire-Revised (SBQ-R). Logistic regression models identified significant risk and protective factors. Models were stratified by rural residence using 2023 Rural-Urban Continuum Codes (RUCC) to examine rural-urban disparities, given WV's predominantly rural yet urban-diverse geography.

Results

In the weighted sample (N=372,665), 27.5% reported lifetime suicide risk. Those with suicidal thoughts were younger (median age 41), unmarried, in poorer health, and often enrolled in Medicaid. Despite WV's rural profile, 60.21% of respondents resided in urban-classified counties. Rural residents showed lower odds of suicidal thoughts or behaviors (aOR = 0.87), but factors such as substance use (aOR = 3.75), unmarried status (aOR = 1.51), and mental health disorders (aOR = 2.93) were significant risk factors.

Implications

Suicide risk factors in WV differ from broader suicidology findings, underscoring the need to address substance use, chronic pain, and mental health in prevention strategies. Further research is needed to explore regional differences in the Appalachian Region for better-targeted interventions.

The impact of social distancing on mental health during the COVID-19 pandemic: a nationwide study of 4.6 million Danish adults

BACKGROUND

Current knowledge on psychiatric illness following periods of social distancing during the COVID-19 pandemic is mostly limited to smaller studies in selected populations. This nationwide study of all 4.6 million Danish adults examined if periods of social distancing were associated with changes in surrogate measures of mental health.

METHODS

All Danish adults (≥18 years) were included and rates of collection of antidepressant prescriptions, psychiatric hospital admissions, and suicide or suicide attempts for the periods March 12, 2020-May 20, 2020 (lockdown period 1), and December 21, 2020-March 1, 2021 (lockdown period 2), were compared to corresponding periods 1 year prior. Individuals were censored due to death or SARS-CoV-2 infection.

RESULTS

Antidepressant consumption increased for both period 1 and period 2, with an incidence rate ratio (IRR) of 1.02 (95% CI: 1.01-1.02, p < 0.001) and IRR 1.08 (95% CI: 1.08-1.09, p < 0.001) respectively, compared to the control periods. Psychiatric hospitalization rates decreased significantly, with an IRR of 0.65 (95% CI: 0.63-0.66, p < 0.001) for period 1, and IRR 0.86 (95% CI: 0.84-0.88, p < 0.001) for period 2. The risk of suicide did not increase in period 1, IRR 0.96 (95% CI: 0.82-1.13, p = 0.64), but seemed increased during period 2, IRR 1.19 (95% CI: 1.02-1.38, p = 0.03).

CONCLUSION

Periods of social distancing during the COVID-19 pandemic were associated with an increase of antidepressant consumption, but decreased rates of psychiatric hospitalization. Suicide risk seemed increased during the second lockdown period.

Role of regular medical visits in mitigating increased suicide risk during the early COVID-19 pandemic in Kobe, Japan

BACKGROUND

Japan has one of the lowest COVID-19 death rates, while the annual suicide rate in 2020 has risen for the first time since 2007. This study aimed to identify high-risk populations and assess the impact of medical visits on suicide trends post-COVID-19 pandemic in Japan.

METHOD

This quasi-experimental study analyzed a population-based database from Hyogo Prefecture (2012-2022). Interrupted time-series analyses identified level and trend changes in monthly suicide rates per 1 million population during the exposure period (2020-2022) versus the control period (2012-2019). Regular visits to primary care and psychiatry stratified analysis.

RESULTS

2181 cases were analyzed, with two-thirds male and a median age of 54. Primary care physicians and psychiatric history were present in 69% and 40% of patients. The study found significant level changes in suicide rates overall (4.14, 95% CI: 1.70, 6.58) among individuals without regular primary care physician visits (2.83, 95% CI: 1.35, 4.32) and without psychiatric visits (2.85, 95% CI: 0.56, 5.14). In contrast, no significant changes were observed in individuals with regular primary care (0.99, 95% CI: -0.78, 2.76) or regular psychiatric visits (0.59, 95% CI: -0.98, 2.16). The trend changes were not significant in any of the groups.

CONCLUSION

This study suggests that a history of attending a medical institution may have prevented the rapid increase in suicides during the early stages of the COVID-19 pandemic.

The trend of suicide and self-harm in the Chinese population from 2018 to 2022 based on ambulance medical emergency cases: a retrospective study

Objective

This study investigates the trends of suicide and self-harm in Nanjing, China, through 4 years of data collection, aiming to provide valuable information for developing effective suicide prevention strategies.

Methods

This descriptive study analyzed Nanjing Emergency Medical Center (NEMC) ambulance records from Nanjing (2018-2022) to investigate suicide and self-harm events. Out of 689,305 records, 4,261 cases were included after exclusions. The study categorized incidents into 4,103 suicide events and 158 self-harm cases. Descriptive statistics and content analysis were conducted to identify characteristics and themes related to these events, with age groups defined according to American Medical Association standards.

Results

The study highlights drug poisoning as the leading method, accounting for 63.56% of the 4,103 suicide events. It notes significant trends by age, gender, and season, with males showing higher rates of self-harm. The study emphasizes the need for targeted prevention strategies, particularly focusing on drug-related suicides among adults and adolescents, as well as the prevalence of various self-harming behaviors.

Conclusion

To reduce self-harm and suicide, interventions must be strengthened for women, who experience higher rates. Key strategies include regulating pesticides and psychotropic drugs, increasing access to mental health resources, and launching community awareness campaigns. Additionally, training healthcare providers and promoting family education can enhance support for women facing mental health challenges.

Understanding the mental health impacts of biological disasters: Lessons from Taiwan's experience with COVID-19

Biological disasters pose a growing challenge in the 21st century, significantly impacting global society. Taiwan has experienced such disasters, resulting in long-term consequences like loss of life, trauma, economic decline, and societal disruptions. Post-disaster, mental health issues such as fear, anxiety, depression, post-traumatic stress disorder (PTSD), and stress surge, accompanied by increased suicide rates. The Coronavirus disease 2019 (COVID-19) (also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) pandemic, recognized as a biological disaster, triggered lockdowns and quarantines in Taiwan, causing lifestyle changes, economic recession, and so on. These shifts may elevate uncertainty about the future, intensifying mental stress and leading to a rise in various mental illnesses. This article reviews mental health studies conducted in Taiwan during the pandemic, emphasizing the need to integrate this research for future preparedness and interventions regarding the mental health impacts of biological disasters, including COVID-19. Further research is essential to explore long-term effects, interventions, and generalizability.

The Impact of the COVID-19 Pandemic on Suicide Attempts in Kerman Province: An Interrupted Time Series Analysis

Background

The COVID-19 pandemic has had a significant impact on global suicide attempt rates. This study evaluated the effect of the COVID-19 pandemic on suicide attempts in the Kerman Province, eastern Iran.

Methods

This is a cross-sectional study. Data on suicide attempt cases in Kerman Province was obtained from the database of Mental, Social, and Addiction Health Office of the Deputy for Health of Medical Sciences Universities from 2018 to 2021. An interrupted time-series model was used to assess the changes in suicide attempts before and after the pandemic.

Results

Suicide attempts exhibited a decreasing trend before the pandemic, with a monthly decrease of 0.9% (P<0.001). The immediate effect of the pandemic indicated that, at the beginning of the pandemic, there was a 4.5% increase in suicide attempts (P=0.134). The sustained effect of the pandemic showed that in the months following the onset of the pandemic, the rate of suicide attempts increased by 1.8% compared to before the pandemic (P<0.001). By the end of 2021, the number of suicide attempts per month exceeded the predicted amount based on pre-pandemic data. Factors such as marital status, education, occupation, place of residence, and previous suicide attempts were found to influence suicide attempts during the pandemic.

Conclusion

Given the significant increase in suicide attempts following the onset of the pandemic, it is crucial to prioritize the implementation of prevention and intervention programs during this crisis.

Unveiling Student Suicides in the Post-Pandemic Period: A Retrospective Analysis of Online News Portals in Bangladesh

Background and Aims

The post-COVID-19 pandemic period has heightened concerns about student mental health and suicide risk in Bangladesh. While studies have explored these issues during the pandemic, post-pandemic student suicides remain under-researched. This study investigates the characteristics, methods, and triggering events associated with suicidal behaviors among students in Bangladesh during the post-pandemic period (2022-2023).

Methods

Data were collected from 150 online newspaper portals in Bangladesh, covering student suicides from 2022 to 2023. Variables such as causes, methods, timing, location, sex, age, and education level were analyzed using Microsoft Excel, SPSS, and ArcGIS.

Results

A total of 984 student suicide cases were identified. Females accounted for 61% of the cases, while males represented 39%, indicating a higher vulnerability among female students. The majority of cases (72.5%) involved students aged 13-19 years, followed by those aged 20-25 years (18.4%). Secondary school students represented 44.9% of the cases, with 7.2% from madrasahs. Hanging was the most common method (79.7%). Major causes included emotional distress (28%), romantic relationship issues (19.5%), academic pressure (8.4%), family problems (8.1%), mental instability (7%), and sexual harassment (3.3%). The Dhaka division reported the highest rate (27.8%) of student suicides. Suicide rates were lowest in August 2022 (4.3%) but spiked in 2023 (12.6%).

Conclusion

This study highlights the significant rise in student suicides in Bangladesh after the pandemic, primarily driven by emotional distress, with females and the 13-19-year age group being most vulnerable. These findings emphasize the urgent need for gender-specific mental health interventions to address this growing issue.

Veränderungen der Verletzungsepidemiologie in der Schwerverletztenversorgung durch die COVID-19-Pandemie: eine retrospektive Analyse des Traumaregisters DGU®

Fragestellung

Die COVID-19-Pandemie führte im Jahr 2020 nicht nur zu einer großen Belastung des deutschen Gesundheitssystems, sondern ging auch mit einer Veränderung des gesellschaftlichen Lebens durch epidemiebedingte Maßnahmen einher. Aus dem erhöhten Behandlungsaufkommen von COVID-19-Erkrankten resultierten ebenfalls veränderte Versorgungsstrukturen in den Kliniken; so zeigte sich unter anderem eine deutlich erhöhte Auslastung der Intensivbetten. Diese retrospektive Registeranalyse des TraumaRegisters DGU® untersucht, inwieweit sich im ersten Jahr der COVID-19-Pandemie in Deutschland 2020 die Epidemiologie und Unfallursachen von Schwerverletzten veränderten und ob eine Veränderung der Verletzungsschwere oder Mortalität von Traumapatienten eintrat.

Material & Methodik

In einer retrospektiven Registeranalyse des TraumaRegisters DGU® der Deutschen Gesellschaft für Unfallchirurgie wurden alle erfassten Traumapatienten der Jahre 2018–2020 eingeschlossen. Die Jahre 2018/2019 wurden als gemeinsame Vergleichsgruppe herangezogen und mit dem ersten Pandemiejahr 2020 verglichen. Neben dem Vergleich der epidemiologischen Daten wurden insbesondere die Unfallursachen und Unfalleinflüsse analysiert. Weiterhin erfolgte eine Mortalitätsanalyse. Zudem führten wir eine Subgruppenanalyse der einzelnen Jahresabschnitte hinsichtlich der einzelnen COVID-19-Infektionswellen im Jahr 2020 durch.

Ergebnis

Insgesamt konnten 71.943 Patienten in die Analyse eingeschlossen werden. Der Injury Severity Score (ISS) zeigte sich in beiden Gruppen annähernd gleich (2020: 17,6 vs. 2018/2019: 17,3). Die Betrachtung des Unfallhergangs ergab eine prozentuale Reduktion an Pkw-assoziiertem Trauma (2020: 17,2 % vs. 2018/2019: 20,7 %) und gleichzeitig eine Zunahme des fahrradassoziierten Traumas (2020: 13,1 % vs. 2018/2019: 10,4 %). Der Anteil der Traumapatienten, die unter Alkoholeinfluss verunfallten, nahm im Jahr 2020 deutlich ab. So zeigte sich insgesamt eine Reduktion von 22,3 % 2018/2019 auf 19,3 % im Jahr 2020. Bezüglich der Mortalität konnte eine Zunahme der Patienten, die im Krankenhaus verstorben sind, festgestellt werden (2020: 11,5 % vs. 2018/2019: 10,3 %).

Schlussfolgerung

Die COVID-19-Pandemie hatte in Deutschland im ersten Pandemiejahr 2020, verglichen mit den beiden Vorjahren, einen Einfluss insbesondere auf den Unfallhergang bei Traumapatienten. Die beobachtete Zunahme der Mortalität ist in weiteren Studien hinsichtlich möglicher Veränderungen von Versorgungsprozessen in den Kliniken durch die COVID-19-Pandemie zu analysieren.

Gender differences and mental distress during COVID-19: a cross-sectional study in Japan

BACKGROUND

To identify risk factors for mental distress and investigate whether the factors were different between men and women during the coronavirus disease 2019 (COVID-19), using KOKOROBO data, which is an online platform that aims to facilitate access to mental health services.

METHODS

We used baseline data on KOKOROBO users 13 years of age or older in Japan who accessed it from October 11, 2021, to April 6, 2023, excluding those receiving treatment for mental health problems. Global severity, based on the most severe measure on Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Insomnia Severity Index (ISI), was analyzed using multivariable logistic regression with baseline characteristics for each gender, and for under 30 and 30 years of age or older in women. We conducted the same analysis of suicidal ideation for each gender.

RESULTS

In the 686 men and 1274 women, 117 (17.1%) and 100 (7.8%) had minimal global severity respectively, and the rest suffered from mental distress to some extent. For women, ages under 30 years (adjusted OR (aOR): 0.352, 95%CI: 0.231-0.539, P < 0.001), marriage (aOR: 0.453, 95%CI: 0.274-0.746, P = 0.002), and concerns about COVID-19 infection were associated with global severity, while having children (aOR: 0.509, 95% CI: 0.284-0.909, P = 0.023) and decrease of going out during the COVID-19 pandemic had a protective effect on global severity and suicidal ideation for men, respectively. Living with family was a risk factor for mental distress in unmarried women over 30 years of age. Less communication with family or others and responding to the questionnaire late at night (00:00-05:59) were associated with severe global severity in both genders.

CONCLUSIONS

Age, living arrangement, marriage, having children, concerns about COVID-19 infection, and lifestyle changes during the COVID-19 pandemic had gender-specific effects on mental distress, while frequent communication and regular life rhythm maintained mental health in both genders. Young women and, unmarried middle-aged women living with their families tended to experience mental distress during the COVID-19 pandemic.

TRIAL REGISTRATION

The Ethics Committee of the National Center of Neurology and Psychiatry approved this study (approval number B2020141) on April 15, 2021.

Suicide rates before and during the COVID-19 pandemic: a systematic review and meta-analysis

PURPOSE

The effects of the COVID-19 pandemic on mental health issues such as depression and anxiety are well-documented in the literature, but its influence on suicidal patterns shows divergent results. We aim to comprehensively synthesize evidence on potential changes or stability of suicide rates during the COVID-19 pandemic worldwide.

METHODS

A comprehensive search of studies reporting suicide rates before and during the COVID-19 pandemic was conducted. Eligible studies reported incidences of confirmed suicides (suspected in special cases) for two time periods, before (until February 2020) and during (from March 2020 to June 2021) the COVID-19 pandemic. A meta-analysis of proportions using a random-effect model was performed to estimate the pre- and during-pandemic incidence rates of suicide with 95% confidence intervals. Differences in pre- and during-pandemic rates were formally tested using a heterogeneity test.

RESULTS

A total of 34 studies were included in the review capturing suicide data from over 40 countries and regions. The meta-analysis outputs did not indicate a significant change in suicide rates during the COVID-19 pandemic. The pooled suicide rate in the studied period before the pandemic was 11.38 per 100,000 (95% CI 9.35-13.42) and in the period during the pandemic was 10.65 per 100,000 (95% CI 8.61-12.68).

CONCLUSION

No significant change in suicide rates was observed during the COVID pandemic from a global perspective for the periods examined. A longer follow-up can provide additional insights into such suicide trends globally. Improvements in data reporting, specifically with implementation of real-time surveillance, is imperative to provide adequate suicide prevention and support.

Resilience Practices in Health Science and Medical Libraries During the Early Stages of the COVID-19 Pandemic

This paper uses the concept of resilience engineering as an organizing principle to discuss best practices that evolved within health science/medical libraries in the United States during COVID-19 crisis, focusing on the period March - August 2020. Protection of library staff, assistance to medical staff, reducing the circulation of misinformation and public health consumerism all required substantial changes to standard processes. These process changes had to arise in the context of both physical isolation and information overload. Some practices became widespread due to their utility, and these are the focus of this report.

"COVID-Collateral" Deaths

Study Design: This observational study focuses on select cases where death may have been related to COVID-related fears or the unintended consequences of protocols or public health mandates imposed during the COVID-19 pandemic. Objective: The objective of this study is to highlight examples of "COVID-collateral" deaths for the expressed purpose of preventing similar deaths in the future. Methods: The study represents a retrospective observational study from the case work at an academically-based regional medical examiners' office. Cases were selected based on identification of deaths that may have been related to COVID-19 fears, mandates or policies. Results: Six cases of COVID-collateral deaths are highlighted in this report, including cases where fear or isolation related to COVID-19 infection resulted in untreated exacerbation of an underlying disease/condition with eventual death, as well as cases where COVID-related psychological/mental stress or isolation played a role in suicide. Conclusions: Medical examiners/coroners should be aware of these cases if future pandemics or similar events occur, so that more thorough and accurate data regarding such deaths can be gathered. Public health officials, the medical community, and the general public also need to be aware of such cases so that appropriate preventive strategies can be employed.

Uncertainties of Economic Policy and Government Management Stability Played Important Roles in Increasing Suicides in Japan from 2009 to 2023

Standardized suicide mortality rates per 100,000 (SMRs) in Japan consistently decreased from 2009 to 2019 but increased from 2020. The causes of these temporal SMR fluctuations remain to be clarified. Therefore, this study was conducted to identify the causalities underlying the recently transformed fluctuations of suicide mortality in Japan. Monthly suicide numbers disaggregated by sex and social standing, and political uncertainty indices, such as economic policy uncertainty (EPU) and government management instability (AENROP), were obtained from Japanese government databases. Interrupted time-series analysis was performed to analyze temporal fluctuations of SMRs disaggregated by sex/social standing associated with the three General Principles of Suicide Prevention Policy (GPSPP) periods and the COVID-19 pandemic. Panel data and vector autoregressive analyses were conducted to investigate causalities from political uncertainties to SMRs. During the first and second GPSPPs (2009-2017), all SMRs disaggregated by sex and social standing decreased, whereas those of unemployed females did not change. During the third GPSPP (2017-2022), decreasing trends in all SMRs were attenuated compared to previous periods. All female SMRs, except unemployed females, showed sharp increases synchronized with the pandemic outbreak. No male SMRs showed sharply increasing at the pandemic outbreak. SMRs of unemployed males/females drastically increased in the later periods of the pandemic, while SMRs of employed and multiple-person/single-person household males did not increase during the pandemic. SMR of unemployed males was positively related to AENROP but not EPU. Other male SMRs were positively related to EPU/AENROP. On the contrary, not all female SMRs were related to EPU/AENROP. Increasing AENROP generally contributed to increasing male SMRs throughout the observation period; however, susceptibility to AENROP and/or political information might have unexpectedly contributed to suppressing the sharply increasing male SMRs induced by large-scale social shocks (the COVID-19 pandemic outbreak) in Japan.

Psychosocial and pandemic-related circumstances of suicide deaths in 2020: Evidence from the National Violent Death Reporting System

PURPOSE

To describe and explore variation in 'pandemic-related circumstances' among suicide decedents during the first year of the COVID-19 pandemic.

METHODS

We identified pandemic-related circumstances using decedents' text narratives in the 2020 National Violent Death Reporting System. We use time-series analysis to compare other psychosocial characteristics (e.g., mental health history, interpersonal difficulties, financial strain) of decedents pre-pandemic (2017/2018: n = 56,968 suicide and n = 7,551 undetermined deaths) to those in 2020 (n = 31,887 suicide and n = 4,100 undetermined). We characterize common themes in the narratives with pandemic-related circumstances using topic modeling, and explore variation in topics by age and other psychosocial circumstances.

RESULTS

In 2020, n = 2,502 (6.98%) narratives described pandemic-related circumstances. Compared to other deaths in 2020 and to the pre-pandemic period, decedents with pandemic-related circumstances were older and more highly educated. Common themes of pandemic-related circumstances narratives included: concerns about shutdown restrictions, financial losses, and infection risk. Relative to decedents of the same age that did not have pandemic-related circumstances in 2020, those with pandemic-related circumstances were more likely to also have financial (e.g., for 25-44 years, 43% vs. 12%) and mental health (76% vs. 66%) psychosocial circumstances, but had similar or lower prevalence of substance abuse (47% vs. 49%) and interpersonal (40% vs. 42%) circumstances.

CONCLUSIONS

While descriptive, these findings help contextualize suicide mortality during the acute phase of the COVID-19 pandemic and can inform mental health promotion efforts during similar public health emergencies.

Nightmare frequency is a risk factor for suicidal ideation during the COVID-19 pandemic

The association between nightmare frequency (NMF) and suicidal ideation (SI) is well known, yet the impact of the COVID-19 pandemic on this relation is inconsistent. This study aimed to investigate changes in NMF, SI, and their association during the COVID-19 pandemic. Data were collected in 16 countries using a harmonised questionnaire. The sample included 9328 individuals (4848 women; age M[SD] = 46.85 [17.75] years), and 17.60% reported previous COVID-19. Overall, SI was significantly 2% lower during the pandemic vs. before, and this was consistent across genders and ages. Most countries/regions demonstrated decreases in SI during this pandemic, with Austria (-9.57%), Sweden (-6.18%), and Bulgaria (-5.14%) exhibiting significant declines in SI, but Italy (1.45%) and Portugal (2.45%) demonstrated non-significant increases. Suicidal ideation was more common in participants with long-COVID (21.10%) vs. short-COVID (12.40%), though SI did not vary by COVID-19 history. Nightmare frequency increased by 4.50% during the pandemic and was significantly higher in those with previous COVID-19 (14.50% vs. 10.70%), during infection (23.00% vs. 8.10%), and in those with long-COVID (18.00% vs. 8.50%). The relation between NMF and SI was not significantly stronger during the pandemic than prior (rs = 0.18 vs. 0.14; z = 2.80). Frequent nightmares during the pandemic increased the likelihood of reporting SI (OR = 1.57, 95% CI 1.20-2.05), while frequent dream recall during the pandemic served a protective effect (OR = 0.74, 95% CI 0.59-0.94). These findings have important implications for identifying those at risk of suicide and may offer a potential pathway for suicide prevention.

Suicide deaths and substance use in Spain between 2010 and 2022

Background

Suicide is a serious public health problem that affects our entire country. The aim of this research was to study the variation in completed suicide rates between 2010 and 2022 in Spain and their relationship with the consumption of addictive substances.

Methods

Completed suicide data from the Spanish Statistical Office (INE) were analyzed with a joinpoint regression model to determine time trends. The relationship between the variation in completed suicide rates with sociodemographic variables, including depression rates, obtained from the Spanish Statistical Office and variables related to the consumption of substances obtained from the survey on alcohol and other drugs in Spain (EDADES) of the Government Delegation for the National Plan on Drugs (DGPNSD) was also studied using an exploratory analysis and also performing a Generalized Additive Model.

Results

The joinpoint regression model did reveal a point of significant change in the period studied for Spain showing a trend of increased suicide death rates for the studied period. The following variables correlated positively with the variation in completed suicide rates in the Generalized Additive Model: alcohol use in the past 12 months, alcohol use in the last 30 days, daily alcohol use in the last 30 days, binge drinking in the last 12 months, binge drinking in the last month, positive Alcohol Use Disorder Test for risky alcohol use, benzodiazepine use in the last 12 months, benzodiazepine use in the last month, daily benzodiazepine use in the last month, use of illegal substances in the last 12 months, use of illegal substances in the last month, mean age and depression rates.

Conclusion

Applying preventive strategies on the risky consumption of alcohol, benzodiazepines and illegal substances would help reduce the rates of completed suicide in Spain.

The long COVID and its mental health manifestations - the review of literature

This article aims to present the overview of the situation during the coronavirus disease 2019 (COVID-19) pandemic about issues concerning the prevalence of mental disorders such as depression, anxiety, rate of suicide attempts, and long COVID (LC) infections in the general population during COVID-19 pandemic. Analysis of the literature (in English, Polish and Spanish language) on topics related to COVID-19, mental disorders (suicide attempts, depression, anxiety) and LC infection published during the 4 years (2020-2023) was done using Pubmed and PubMed Central search engine. Keywords such as "COVID-19," "mental disorders," "long COVID infection," "depression," "anxiety," "suicide attempts" were used during the search. The conduct of this review/comment followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) protocol, which corresponds to a checklist of 27 items designed to facilitate the development and reporting of a robust protocol for systematic reviews or meta-analyses. Overall 35 studies were selected and analyzed in the review on topics: including among others LC (14 studies), suicide attempts (7 studies), mental disorders (depression, anxiety) (14 studies). The main issues raised in the articles were: higher risk of LC symptoms in women, fatigue and brain fog listed as frequently encountered patient's complaints together with anxiety, depression, loneliness, especially in younger age groups and in women. Issues regarding LC, mental disorders and suicide attempts requires further research as the results vary in different countries. Int J Occup Med Environ Health. 2024;37(3):360-80.

Identifying Reddit Users at a High Risk of Suicide and Their Linguistic Features During the COVID-19 Pandemic: Growth-Based Trajectory Model

BACKGROUND

Suicide has emerged as a critical public health concern during the COVID-19 pandemic. With social distancing measures in place, social media has become a significant platform for individuals expressing suicidal thoughts and behaviors. However, existing studies on suicide using social media data often overlook the diversity among users and the temporal dynamics of suicide risk.

OBJECTIVE

By examining the variations in post volume trajectories among users on the r/SuicideWatch subreddit during the COVID-19 pandemic, this study aims to investigate the heterogeneous patterns of change in suicide risk to help identify social media users at high risk of suicide. We also characterized their linguistic features before and during the pandemic.

METHODS

We collected and analyzed post data every 6 months from March 2019 to August 2022 for users on the r/SuicideWatch subreddit (N=6163). A growth-based trajectory model was then used to investigate the trajectories of post volume to identify patterns of change in suicide risk during the pandemic. Trends in linguistic features within posts were also charted and compared, and linguistic markers were identified across the trajectory groups using regression analysis.

RESULTS

We identified 2 distinct trajectories of post volume among r/SuicideWatch subreddit users. A small proportion of users (744/6163, 12.07%) was labeled as having a high risk of suicide, showing a sharp and lasting increase in post volume during the pandemic. By contrast, most users (5419/6163, 87.93%) were categorized as being at low risk of suicide, with a consistently low and mild increase in post volume during the pandemic. In terms of the frequency of most linguistic features, both groups showed increases at the initial stage of the pandemic. Subsequently, the rising trend continued in the high-risk group before declining, while the low-risk group showed an immediate decrease. One year after the pandemic outbreak, the 2 groups exhibited differences in their use of words related to the categories of personal pronouns; affective, social, cognitive, and biological processes; drives; relativity; time orientations; and personal concerns. In particular, the high-risk group was discriminant in using words related to anger (odds ratio [OR] 3.23, P<.001), sadness (OR 3.23, P<.001), health (OR 2.56, P=.005), achievement (OR 1.67, P=.049), motion (OR 4.17, P<.001), future focus (OR 2.86, P<.001), and death (OR 4.35, P<.001) during this stage.

CONCLUSIONS

Based on the 2 identified trajectories of post volume during the pandemic, this study divided users on the r/SuicideWatch subreddit into suicide high- and low-risk groups. Our findings indicated heterogeneous patterns of change in suicide risk in response to the pandemic. The high-risk group also demonstrated distinct linguistic features. We recommend conducting real-time surveillance of suicide risk using social media data during future public health crises to provide timely support to individuals at potentially high risk of suicide.

Suicide-Related Emergency Department Visits Before and During the COVID-19 Pandemic in the United States

Background and aim  The impact of COVID-19 on suicide rates is a significant concern, given the widely recognized psychological effects that the pandemic has had on mental health. Overall, suicide trends remained relatively stable. Yet, specific age groups, races, and genders experienced an increase in suicide rates. A better understanding of suicide trends over time is critical to identifying and addressing mental health crises exacerbated by the pandemic. This study aimed to study whether the years preceding and during the pandemic were associated with an increase in emergency department (ED) visits in the United States for suicide or intentional injury.  Methodology Secondary analyses of data from the National Hospital and Ambulatory Medical Care Survey (2018-2021) were conducted. The frequency of ED visits due to intentional injury or suicide was compared in 2018-2019 (pre-COVID-19 pandemic onset) to those of 2020-2021 (during-COVID-19 onset). Logistic regression was used to estimate odd ratios (ORs) and corresponding 95% confidence intervals. Patient's race, sex, age, and regional differences were assessed as covariates. Results There were 27,516 and 22,247 visits assessed in the pre- and during-COVID-19 periods, respectively. In total, 1,375 visits were due to intentional injury/suicide. No differences were found comparing the proportion of visits due to intentional injuries/suicide pre- and during-COVID-19 periods (2.6% in both) The adjusted OR (aOR) comparing pre- versus during-COVID-19 for emergency room visits due to intentional injury/suicide was not significantly different from 1 (aOR = 0.98, 95% CI 0.84-1.15). The odds of suicide/intentional injury were 53% higher in males (aOR = 1.53, 95%CI 1.30-1.81), in those with ages 18-44 years (aOR = 7.24, 95% CI 4.92-10.67) and 45-64 years (aOR = 3.55, 95% CI 2.31-5.47) compared to those 65 years or older, and in non-Hispanic Black individuals compared to non-Hispanic White individuals (aOR = 1.29, 95% CI 1.05-1.58).  Conclusions Using a national sample of ED visits, we found no association between the pre- and COVID-19 pandemic periods and the proportion of visits due to intentional injury/suicide. However, the study's proportional prevalence design limits its ability to estimate actual risk, requiring a cautious interpretation of the findings. Despite these limitations, the observed increased odds of suicide or intentional injury in specific subgroups underscore the need for targeted interventions. Further research is crucial to assess the long-term impacts of COVID-19.

Suicides, Other External Causes of Death, and Psychiatric Status in Suicide Attempters: A National Registry-Based Analysis in Israel, 2006-2020

OBJECTIVE

To assess risk factors and rates of suicide and other external cause deaths, among suicide attempters compared to the total population, stratified by psychiatric hospitalization discharge and mental diagnosis.

METHODS

A national registry-based analysis of suicide and external cause mortality was performed among suicide attempters between 2006 and 2020 in Israel in the National Hospital ED database. Data was stratified by psychiatric hospitalization status by linking to the national psychiatric case registry. Age adjusted mortality rates were calculated.A multivariate cox regression model assessed the relative risk of demographic factors and psychiatric diagnosis and hospitalization on outcomes.

RESULTS

Among 57,579 first suicide attempters, of whom 16,874 had a psychiatric hospitalization, there were 853 suicides (1.5%) and 473 deaths from other external causes (0.8%), 485 suicides (2.9%) and 199 external cause deaths (1.2%) in the psychiatric group. Suicide risk was highest in the year after the attempt, but continued throughout the study, particularly in the psychiatric hospitalized group. Suicide rates within one year of first suicide attempt were 137 (95% CI 122-152) times higher than the total population, 190 (155-233) times in females and 128 (112-145) times in males, 178 (153-207), 243 (181-325) and 158 (132-190) times higher, respectively, in those with a psychiatric hospitalization.

CONCLUSIONS

We found a greatly increased risk for suicide and significant increase for other external causes of death amongst a cohort of suicide attempters, compared to the total population, particularly those with a history of psychiatric hospitalization.

Neural activity during inhibitory control predicts suicidal ideation with machine learning

Suicide is a leading cause of death in the US and worldwide. Current strategies for preventing suicide are often focused on the identification and treatment of risk factors, especially suicidal ideation (SI). Hence, developing data-driven biomarkers of SI may be key for suicide prevention and intervention. Prior attempts at biomarker-based prediction models for SI have primarily used expensive neuroimaging technologies, yet clinically scalable and affordable biomarkers remain elusive. Here, we investigated the classification of SI using machine learning (ML) on a dataset of 76 subjects with and without SI(+/-) (n = 38 each), who completed a neuro-cognitive assessment session synchronized with electroencephalography (EEG). SI+/- groups were matched for age, sex, and mental health symptoms of depression and anxiety. EEG was recorded at rest and while subjects engaged in four cognitive tasks of inhibitory control, interference processing, working memory, and emotion bias. We parsed EEG signals in physiologically relevant theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) frequencies and performed cortical source imaging on the neural signals. These data served as SI predictors in ML models. The best ML model was obtained for beta band power during the inhibitory control (IC) task, demonstrating high sensitivity (89%), specificity (98%). Shapley explainer plots further showed top neural predictors as feedback-related power in the visual and posterior default mode networks and response-related power in the ventral attention, fronto-parietal, and sensory-motor networks. We further tested the external validity of the model in an independent clinically depressed sample (n = 35, 12 SI+) that engaged in an adaptive test version of the IC task, demonstrating 50% sensitivity and 61% specificity in this sample. Overall, the study suggests a promising, scalable EEG-based biomarker approach to predict SI that may serve as a target for risk identification and intervention.

Mental Health Treatment Use, Perceived Treatment Need, and Reasons for Non-Use Among U.S. Adults with Serious Suicidal Thoughts During the COVID-19 Pandemic

Analyzing the 2021 National Survey on Drug Use and Health data with generalized linear models, we examined: (1) COVID pandemic-related and other correlates of mental health treatment use and unmet perceived treatment need among U.S. adults who experienced serious suicidal thoughts (N = 3,177); and (2) correlates of self-reported reasons for not receiving treatment. We found that 61% used any mental health treatment, and 48% of users and 37% of nonusers reported perceived treatment need. Significant correlates of treatment use were demographic factors, insurance, major depressive disorder, and illicit drug use disorder. Significant correlates of perceived treatment need were age 18-34, some college education, and major depressive episode. Perceived negative effect of the COVID pandemic on mental health was a significant factor for both treatment use and perceived need. The most frequent reasons for not getting treatment were the cost of treatment or lack of insurance and stigma-related concerns.

Follow-up of telemedicine mental health interventions amid COVID-19 pandemic

The initiation of the program Mental Health Support Program for Coronavirus Infection addressed the increased demand for mental health services in the province of Salamanca, resulting from the COVID-19 pandemic. The psychiatry service provided care for COVID-19 patients, their families, and healthcare workers who treated them, as these groups were identified as being at risk. This study aims to describe the assistance provided, including personnel and resources utilized, types of interventions carried out, and to assess the demand for mental health care and predominant symptoms and emotions experienced by patients. Billboards and the complex's intranet publicized the program. Specific clinical approach using telemedicine were provide from March 2020 to December 2021 to COVID-19 patients, their relatives, and healthcare workers. 216 patients were included with a mean age of 53.2 years, with women comprising 77.3% of this group. All the groups received treatment in similar proportions. Over a period of 730 h, a total of 1376 interventions were performed, with an average duration of 31.8 min per intervention. The program could treat 79.6% of these patients without requiring referrals to other services. When the program concluded, only 21 participants (9.7%) were discharged to the local mental health network to continue their mental health treatment. The program effectively reduced the burden on regular mental health services due to its ability to treat most patients without requiring referrals. The program was able to attend to most mental health requests with minimal involvement of the regular mental health service.

University Students with Current Suicidal Ideation and Perceived Changes during the COVID-19 Pandemic: A Qualitative Study

INTRODUCTION

Mental health problems seemed to have increased among university students during the COVID-19 pandemic. To deepen our understanding of the pandemic's effects in this population, we conducted qualitative research to investigate any perceived changes in students during the pandemic, differentiating the sample based on the presence or absence of current suicidal ideation (SI).

METHODS

A wide sample of Italian university students (n = 1,214) completed an online questionnaire during the COVID-19 pandemic, March 2020-June 2021. We conducted a computer-assisted content analysis of an open-ended question about the perceived changes that occurred to them during the pandemic.

RESULTS

(1) Four thematic clusters were identified: "The psychological impact of the pandemic," "New ties and new loneliness," "An uncertain forethought" and "Discovering the value of relationships." (2) In subjects characterized by severe SI, the state of confinement at home was related to the most intense emotional states and worries. (3) Students with severe SI were different from the others, in particular using the lemma "panic," which was the only psychological state specifically associated with this group.

CONCLUSIONS

Students with current severe SI experienced higher level of psychological distress and suffering compared to the other groups during the pandemic.

Characteristics of drug overdose suicide attempts presenting to the psychiatric emergency department of Beijing Anding Hospital

BACKGROUND

Overdose-related suicide attempts represent a significant portion of self-harm presentations in the psychiatric emergency department (ED). Identifying specific patient characteristics associated with these attempts holds promise for pinpointing drug classes with elevated risk and paving the way for tailored suicide prevention interventions. This study aims to examine the demographic profiles of ED patients who had experienced overdose-related suicide attempts.

METHODS

This retrospective study was conducted at Beijing Anding Hospital, Capital Medical University, from January 2020 to December 2021. Patients with psychiatric drug overdose suicide attempts presenting to the psychiatric ED were included. Sociodemographic characteristics and the specific classes of drugs involved were collected, and analysed descriptively.

RESULTS

This study examined 252 overdose patients, excluding 51 patients treated with alcohol or nonpsychiatric drugs, and a total 201 cases were included. The mean age of the patients was 28 ± 16 years (median 23, range 12-78), and 82% (n = 165) of the sample were females. Notably, nearly half (45%) of the patients were aged ≤ 20 years. While the number of cases decreased with increasing age, a significant increase was observed in 2021 compared to 2020. Benzodiazepines (BZDs) were the most frequently implicated substance class (n = 126, 63%), followed by antidepressants (n = 96, 48%), antipsychotics (n = 44, 22%), Z-drugs (n = 43, 21%), and mood stabilizers (n = 36, 18%). For adolescents, antidepressants (n = 52, 71%) overtook BZDs (n = 38, 52%) as the most common drug. The monthly distribution of cases revealed peaks in April and November. Furthermore, 21% (n = 42) of patients ingested more than two psychotropic medications concurrently. Finally, approximately half (n = 92) of the patients required inpatient admission for further treatment. Comparisons between hospitalized and nonhospitalized patients did not reveal any significant differences.

CONCLUSIONS

The present study revealed a greater prevalence of suicide overdose attempts among young females receiving prescriptions for antidepressants and/or BZDs. This finding suggests a potential need for enhanced monitoring of suicidal behaviour in this specific population when prescribing psychotropic medications. These findings contribute to the growing body of knowledge regarding drug overdose suicide attempts in psychiatric emergency settings and underscore the importance of further research to develop targeted prevention interventions.

The Impact of COVID-19 on Suicidal Behavior in King Abdulaziz Medical City in Saudi Arabia

INTRODUCTION

 During the COVID-19 pandemic, there has been a global increase in mental health issues, including suicidal behaviors. This study focuses on assessing the impact of the pandemic on the prevalence and characteristics of suicidal behavior at King Abdulaziz Medical City in Riyadh, Saudi Arabia.

METHODS

A retrospective cohort study was conducted on 580 patients from January 2017 to December 2022, focusing on those aged 18 and above referred for suicide evaluation. Data were collected via chart reviews and analyzed using Statistical Product and Service Solutions (SPSS, version 25; IBM SPSS Statistics for Windows, Armonk, NY).

RESULTS

Our study reviewed 580 patient charts, with 555 (95.7%) meeting the inclusion criteria. The majority of participants were in the 18-29 age group (66.7%). We observed an increase in the number of cases undergoing suicide attempt assessment post COVID-19, with 296 incidents (53.3%) from March 2020 to December 2022 (about a year and eight months), compared to 259 incidents (46.7%) from January 2017 to March 2020 (over three years). A significant post-pandemic increase was noted in individuals with secondary education or higher (p = 0.004). No significant changes were found in other demographic variables or in the profiles of individuals with an intention to end life before and after the pandemic.

CONCLUSION

The study highlights the nuanced impact of the COVID-19 pandemic on suicidal behavior in Saudi Arabia, revealing an increased demand for suicide assessments, particularly among educated individuals. However, no corresponding increase was observed in the rate of high-intent suicidal cases or other significant variables. The findings underscore the complexity of factors influencing suicidal behavior during the pandemic and the need for targeted mental health interventions. Future research, ideally supported by a national database, is essential for a comprehensive understanding of suicidal behavior in Saudi Arabia.

History of Suicidality and Pandemic Outcomes: Longitudinal Associations with Anxiety Symptoms, Depressive Symptoms, and Problematic Drinking

Objective

Individuals with a history of suicidality may be especially vulnerable to the adverse impact of COVID-related stressors, but this vulnerability has not been demonstrated. This study examined the longitudinal effects of suicidality history (ideation only or attempt vs. none) and interactions with COVID-related stressors (e.g., work interruptions, childcare challenges, and financial stress) on anxiety symptoms, depressive symptoms, and problematic drinking.

Methods

Longitudinal data from 517 participants were drawn from the National Institute on Alcohol Abuse and Alcoholism Natural History Protocol and COVID-19 Pandemic Impact on Alcohol Study. Lifetime history of suicidality was assessed using the clinician administered Columbia-Suicide Severity Rating Scale. Multiple regressions tested the interaction between suicidality history and COVID-related stressors on clinical outcomes.

Results

Compared to individuals without any history of suicidality (79.9%; n = 413), individuals with a history of suicide ideation only (14.5%; n = 75) and suicide attempt (5.6%; n = 29) had higher anxiety symptoms, depressive symptoms, and problematic drinking during the pandemic. Significant interaction effects showed the associations between COVID-related stressors and mental disorder symptoms were stronger among individuals with suicide attempt history than individuals without suicidality history.

Conclusions

History of suicide attempt in combination with high COVID-related stressors put individuals at the greatest risk for pandemic mental disorder symptoms. Individuals with suicide attempt history may have lower coping resources to handle COVID-related stressors. Suicide risk assessment and intervention to increase cognitive flexibility and emotional regulation skills may help these individuals manage emotional distress experienced during the COVID-19 pandemic and beyond.

Impacts of Working Hours, Wages, and Regular Employment Opportunity on Suicide Mortalities of Employed and Unemployed Individuals before and during the COVID-19 Pandemic in Japan

Standardized suicide mortality rates per 100,000 population (SMRs) in Japan consistently decreased from 2009-2019, but these decreasing trends were reversed to increase in 2020. To clarify the mechanisms of recent increasing suicide in Japan, temporal fluctuations of SMRs disaggregated by sex and employment status (employed and unemployed individuals) and labor indices such as working hours, wages, and regular employment opportunity index (REO) from January 2012 to June 2023 were analyzed using interrupted time-series analysis. Additionally, temporal causalities from labor indices to SMRs were analyzed using vector autoregressive and non-linear auto-regressive distributed lag analyses. Decreasing trends among employed SMRs of both sexes were attenuated after the enactment of the "Work Style Reform Program" in 2018, but male SMRs were unaffected by the COVID-19 pandemic. However, female employed SMRs sharply increased, synchronized with the "Work Style Reform Act" and the COVID-19 pandemic outbreak (the COVID-19 impact was greater than the "Work Style Reform Act"). Additionally, unemployed SMRs of both sexes sharply increased with the revision and scale-down of countermeasures against economic deterioration caused by COVID-19 ("revision of economic supportive countermeasures against economic deterioration caused by COVID-19"). Unexpectedly, after enacting the "Work Style Reform Act", wages decreased due to possibly decreasing working hours. Increasing REO, which consistently increased, was a protective factor for male suicides, but unemployed SMRs were not affected by any labor indices. It has been established that controlling a heavy workload plays an important role in suppressing the deterioration of physical and mental conditions, including suicide; however, this study suggested that, at least within appropriate ranges of working hours, decreasing working hours due to excessive management probably contributes to increasing suicides of some vulnerable individuals via de-creasing their wages. Although governmental welfare and economic support measures had to be revised according to rapidly changing situations during the COVID-19 pandemic, this study also suggested that temporal gaps among a part of revisions of several welfare and economic support measures were unexpectedly involved in drastically/sharply increasing suicides of unemployed individuals in 2022.

Number and nature of psychiatric emergency department visits in a tertiary hospital before, during, and after coronavirus pandemic

Introduction

The COVID-19 pandemic has significantly impacted mental health globally, leading to a deterioration in the overall mental health of the population and changes across all healthcare levels, including emergency departments (ED). However, the evolution of the quantity and nature of psychiatric ED visits in the post-pandemic period remains uncertain.

Aims

To examine changes in the number and nature of psychiatric emergencies at a general hospital before, during, and after the COVID-19 pandemic.

Materials and methods

Psychiatric ED visits from a tertiary hospital in the Basque Country (Spain) between January 2019 and November 2023 were investigated. Electronical health registers detailing the number and nature of psychiatric care consultations were analyzed for the study timeframe. Three periods were then compared: pre-pandemic (from January 2019 to February 2020), pandemic (from March 2020 to January 2022), and post-pandemic (from February 2022 onwards).

Results

16,969 psychiatric ED visits were recorded for the study period. The number of psychiatric ED visits remained stable from pre-pandemic (269.93 visits/month) to pandemic (264.48 visits/month) periods but experienced a significant rise during the post-pandemic period (330.00 visits/month; t=-6.42; p<0.001), which was not reflected in medical and traumatological visits. The proportion of visits for anxiety (Z=-2.97; p=0.003), suicidal ideation (Z=-5.48; p<0.001), and administrative and social consultations (Z=-5.69; p<0.001) increased over the course of the pandemic. In contrast, visits for schizophrenia and other psychotic disorders (Z=4.85; p<0.001), as well as unspecified behavioral alterations (Z=2.51; p=0.012), significantly decreased.

Conclusion

The COVID-19 pandemic and its aftermath have altered the patterns of urgent psychiatric care, characterized by a sharp increase of average monthly number of consultations and a shift in their nature. Future efforts should focus on characterizing this surge in demand and enhancing both emergency services and outpatient settings.

Psychosocial stress, adult suicidal ideation, and the mediating effect of poor sleep quality during the COVID-19 pandemic in South Africa

OBJECTIVES

South Africa instituted one of the world's strictest lockdowns during the COVID-19 pandemic, which generated heightened conditions of psychosocial stress and posed widespread mental health risks. Despite the elevated burdens of suicidal behaviors and risk of psychiatric disease in the country, few studies have examined the impacts of psychosocial stress from the pandemic on suicidal ideation in South Africa. This study examined the association between psychosocial stress experienced under the COVID-19 pandemic and adult suicidal ideation, as well as degree to which sleep quality and duration mediated this relationship.

METHODS

An online survey assessed experiences of COVID-19 psychosocial stress, sleep quality and duration, and suicidal ideation in a sample of 189 South African adults during the second and third waves of the COVID-19 pandemic. A causal inference framework for mediation analysis was used to assess the degree to which sleep quality and duration explained the association between COVID-19 psychosocial stress and suicidal ideation.

RESULTS

Suicidal ideation was reported in 21% of adults. Adults described having moderate sleep quality and an average of 6.9 hours of sleep per night. COVID-19 psychosocial stress significantly predicted adult suicidal ideation in fully adjusted models. Sleep quality, but not sleep duration, significantly mediated the association between COVID-19 psychosocial stress and suicidal ideation, accounting for 25.9% of the total effect.

CONCLUSIONS

Poor sleep quality may play an important role in exacerbating the alarming stress-induced mental health effects of the COVID-19 pandemic. Further research is necessary to understand the underlying sleep dynamics and associated psychological and neurobiological processes that perpetuate adult suicidal ideation.

Recovering from the first shock? Changes in suicidality during the first two years of the COVID-19 pandemic in a country with traditionally high levels of completed suicides

BACKGROUND

Hungary was among the few countries where suicidality increased in the first year of the COVID pandemic. In this study, we sought to investigate whether that elevated suicide mortality had changed by 2021, when the number of fatalities due to COVID-19 was much higher than in 2020.

METHODS

We used an interrupted time-series analysis with (quasi-) Poisson regression, controlling for linear trend and seasonal effects, to estimate the effect of the pandemic on the suicide rates of various subpopulations. For both pandemic years the changes in risk of suicide were compared to the period between 2015 and 2019.

RESULTS

Although the pandemic had a significant adverse effect on suicidality in 2020 in the Hungarian total population and in males, by 2021 this effect had vanished. In the total population, those aged 25 years and older had elevated suicidality in 2020 but neither age group in the total population had elevated suicidality in 2021. In the total population, increased risks of suicide death could be observed among residents of the capital city (in 2020 and 2021), villages (in 2020), and - in terms of regions - "Central Hungary" (in 2020 and 2021). Only the risk of violent suicides was significantly higher for both the total and male populations (and only in 2020).

LIMITATIONS

We used non-individual level data.

CONCLUSIONS

The increased suicidality in 2020 had abated by 2021. In the paper, we discuss the possible explanations for our findings.

The Inter-Relationships Between Depressive Symptoms and Suicidality Among Macau Residents After the "Relatively Static Management" COVID-19 Strategy: A Perspective of Network Analysis

Background

Suicidality is a global public health problem which has increased considerably during the coronavirus disease 2019 (COVID-19) pandemic. This study examined the inter-relationships between depressive symptoms and suicidality using network analysis among Macau residents after the "relatively static management" COVID-19 strategy.

Methods

An assessment of suicidal ideation (SI), suicide plan (SP), suicide attempt (SA) and depressive symptoms was conducted with the use of individual binary response items (yes/no) and Patient Health Questionnaire (PHQ-9). In the network analysis, central and bridge symptoms were identified in the network through "Expected Influence" and "Bridge Expected Influence", and specific symptoms that were directly associated with suicidality were identified via the flow function. Network Comparison Tests (NCT) were conducted to examine the gender differences in network characteristics.

Results

The study sample included a total of 1008 Macau residents. The prevalence of depressive symptoms and suicidality were 62.50% (95% CI = 59.4-65.5%) and 8.9% (95% CI = 7.2-10.9%), respectively. A network analysis of the sample identified SI ("Suicidal ideation") as the most central symptom, followed by SP ("Suicide plan") and PHQ4 ("Fatigue"). SI ("Suicidal ideation") and PHQ6 ("Guilt") were bridge nodes connecting depressive symptoms and suicidality. A flow network revealed that the strongest connection was between S ("Suicidality") and PHQ6 ("Guilt"), followed by S ("Suicidality") and PHQ 7 ("Concentration"), and S ("Suicidality") and PHQ3 ("Sleep").

Conclusion

The findings indicated that reduction of specific depressive symptoms and suicidal thoughts may be relevant in decreasing suicidality among adults. Further, suicide assessment and prevention measures should address the central and bridge symptoms identified in this study.

The Impact of the COVID-19 Pandemic on Self-Harm Attempts Observed in a Hospital Emergency Department

Suicide is a significant public health concern, with one million lives lost to it every year. Suicidal ideation and attempts are markers of high risk. The COVID-19 pandemic has had a negative psychological impact on the population. This study aims to describe and analyze the clinical and sociodemographic characteristics of patients who have received medical attention for self-harm attempts in a hospital emergency department, comparing the period before and after the COVID-19 pandemic. This is a descriptive, retrospective study that collected data from medical records of patients who received care for self-harm attempts in the emergency department. The data included cases from 1 January 2018 to 31 December 2022. In total, 529 cases of self-harm attempts were identified, of which 62.8% were female. The number of post-pandemic self-harm attempts significantly increased compared to the period before the pandemic. The most used method for self-harm was medication ingestion. This study revealed that over one-third of the participants had previously attempted suicide. Most self-harm attempts were made by women in the 10-20 or 41-50 age groups, with a history of psychiatric illness and multiple medications. The study results also highlighted an increase in self-harm attempts during the COVID-19 pandemic.

Incidence of suicidal ideation in a cohort of civil servants during the COVID-19 pandemic in Brazil: insights from the ELSA-Brasil Study

OBJECTIVE

This study investigated the incidence of suicidal ideation and its associated risk factors in the state of São Paulo in the Brazilian Longitudinal Study of Adult Health (Estudo Longitudinal de Saúde do Adulto [ELSA-Brasil]) cohort during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

In a pre-pandemic ELSA-Brasil onsite assessment in 2016-2018 (wave 3) and a pandemic online assessment in May-July 2020 (wave COVID), we assessed suicidal ideation using the Clinical Interview Schedule-Revised (CIS-R). Single and multi predictor logistic regressions were performed using sociodemographic characteristics, household financial impact during the pandemic, presence of previous chronic diseases, alcohol abuse, adverse childhood experiences (ACE), living alone, and previous common mental disorders (CMD) as predictors. Incidence of suicidal ideation was used as outcome.

RESULTS

Out of 4,191 participants in wave 3, 2,117 (50.5%) also answered the COVID wave. There was a threefold increase in suicide ideation, from 34 (1.8%) to 104 (5.6%) participants. In multiple predictor models, we found that previous CMD (odds ratio [OR] 7.17; 95% confidence interval [95%CI] 4.43 - 11.58) and ACE (OR 1.72; 95%CI 1.09 - 2.72) increased the odds of incident suicidal ideation. The sociodemographic predictors female sex, younger age, and low income were significant risk factors in the single predictor models only.

CONCLUSIONS

These findings underscore the importance of monitoring and supporting individuals who suffered ACE and have a history of mental health disorders. This is especially critical in times of heightened societal stress, such as the COVID-19 pandemic.

The Impact of COVID-Related Restrictions on the Mental Health of Students

The first stage of the COVID pandemic in spring and early summer of 2020 was shaped by restrictions due to the so-called flattening-the-curve approach. Students globally were impacted when public and private colleges and universities were forced to either shut down temporarily or transition to remote learning. Studies from around the world found increased levels of stress, anxiety, depression, and suicidal ideation. Female students often reported being more affected than male students. Suicide rates, however, did not increase. The second stage, starting in late summer 2020, saw the highest case numbers but also a slow and mostly partial return to normal life enabled by vaccination efforts and policy decisions. The mental health of students in most countries recovered well, even when they had to go through repeated or continued lockdowns or restrictions. Although it cannot be predicted what portion of students will be affected by mental health issues in ten or twenty years, it is certain that there will be long-term mental health consequences for many. It is also uncertain which approach, "living with COVID" or "zero COVID," will show less impact on the mental health of students' long term.

Anomic suicides on rise during recently emerging crises: revisiting Durkheim's model

Suicide is a global public health issue, with behavior differing across genders, age groups, places, and sociopolitical settings. Emile Durkheim characterized anomic suicide as occurring when social standards fail, resulting in purposelessness and directionlessness. Young people who are experiencing social issues are in danger, even if they do not voice suicidal ideas. Prevention interventions should target these people by strengthening resilience, minimizing social dysregulation stress, and fostering the development of life skills, coping resources, and social support. Anomic suicide has important psychological and societal implications, emphasizing the importance of fostering social cohesion and assisting persons experiencing purposelessness or a lack of direction in life.

Trends in suicide mortality in Spain from 1998 to 2021 and its relationship with the COVID-19 pandemic: A joinpoint regression analysis

In the European Union, a rate of 11.9 cases per 100,000 was estimated in 2019.In Spain, suicide is the leading cause of external death. Social crises can have an impact on suicide rates. We analyzed changes in suicide mortality trends in Spain following the COVID-19 pandemic. We used statistical data from the National Institute of Statistics of Spain (1998-2021). We calculated age-specific rates, age and sex-adjusted rates, and analyzed trends and changes using joinpoint-regression models. Rates decrease in both sexes at the ages of 65 and older. In women, they increase in the ages of 1-29 years and 45-59 years. In men, they decrease in the ages of 15-39 years. Among women, age-adjusted rates remained stable between 1998 and 2021, with a non-significant annual decrease of 0.4 %. Among men, there was a significant annual decrease of 0.7 %. The years 2020 and 2021 had 8 % higher mortality compared to the two years prior to the COVID-19 pandemic. Suicide mortality in Spain slightly decreased among men and remained stable among women between 1998 and 2021, but there seems to be an increase following the COVID-19 pandemic.

Impacts of Complete Unemployment Rates Disaggregated by Reason and Duration on Suicide Mortality from 2009-2022 in Japan

In Japan, suicides had consistently decreased before the COVID-19 pandemic (from 2009-2019), but conversely increased after the pandemic outbreak (from 2020-2022). To identify the features of fluctuations of suicides in Japan, the standardized suicide mortality rates per 100,000 population (SMRP) disaggregated by gender (males/females) and age (10-year cohorts) from 2009-2022 were analyzed using interrupted time-series and joinpoint regression analyses. Temporal causalities from unemployment rate (CUR) disaggregated by unemployment duration and reasons for seeking work to SMRP were analyzed using vector autoregressive modelling with Granger causality analysis. SMRP fluctuations from 2009-2022 were composed of three patterns, such as positive discontinuity (increasing) synchronized with the pandemic outbreak, attenuations of decreasing trends before the pandemic, turning from decreasing before the pandemic to increasing/unchanging after the pandemic outbreak. Dismissal CUR positively related to SMRP of working-age generations, whereas voluntary CUR negatively related to SMRP of younger population (<30 years), which turned to persistently increasing before the pandemic (approximately 2016-2017). CUR shorter than 3 months positively related to SMRP of working-age females, which displayed promptly increasing synchronization with the pandemic outbreak. CUR longer than 12 months positively related to SMRP of working-age males, which contributed to persistently increasing SMRPs during the pandemic. These results suggest that increasing SMRP during 2020-2022 in Japan has been probably at-tributed to interactions among the pandemic-related factors, continuous vulnerabilities from before the pandemic and newly developing risk factors for suicides during the pandemic. Unexpectedly, increasing SMRPs of working-age males in 2022 suggest that either prolongation of the pandemic or the ending of the pandemic might positively affect suicides in Japan.

Prevalence of suicidal behavior in patients with chronic pain: a systematic review and meta-analysis of observational studies

Objective

Chronic pain is a leading cause of disability, severely impairing an individual's daily activity and quality of life. In addition, this condition may contribute to suicidal thoughts by leading to neuropsychological impairments, a perceived lack of meaning in life, and pain-related catastrophizing. This systematic review aimed to comprehensively investigate the prevalence and associated factors of suicidal behaviors (SBs) including suicidal ideation (SI) and suicide attempt (SA) or its complete, in individuals with chronic pain.

Methods

Five electronic databases were searched up to October 4, 2022. Only observational studies investigating the prevalence of SB in individuals with chronic pain were included. The methodological quality of the included studies was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. A meta-analysis was conducted to quantify the prevalence of SB in the population, and the command "Metaprop" was used in STATA/MP 16. In addition, factors explaining the association between chronic pain and SB identified through regression analysis were investigated.

Results

A total of 19 studies were included in this review (N = 3,312,343). The pooled lifetime prevalence of SI and SA was 28.90% (95% confidence interval, 17.95 to 41.26%) and 10.83% (5.72 to 17.30%), respectively, in a mixed sample comprising various chronic pain conditions. Importantly, the pooled prevalence of past 2-week SI was as high as 25.87% (18.09 to 34.50%). The methodological quality of the included studies was not optimal, and studies using validated SB assessment tools were lacking. Potential protective factors against SB in this population included pain coping and self-efficacy, older age, certain race/ethnicity groups, and marriage.

Conclusion

This systematic review and meta-analysis demonstrated the high prevalence of SB in individuals with chronic pain. Specifically, around 1 in 4 individuals with chronic pain had SI within the last 2 weeks. However, there was considerable heterogeneity in the pooled prevalence of SB in this population.

Positive affect training to reduce mental health problems during the COVID-19 pandemic: a proof-of-concept randomised clinical trial

BACKGROUND

The social restrictions occurring during the pandemic contributed to loss of many sources of reward, which contributes to poor mental health.

OBJECTIVE

This trial evaluated a brief positive affect training programme to reduce anxiety, depression and suicidality during the pandemic.

METHODS

In this single-blind, parallel, randomised controlled trial, adults who screened positive for COVID-19-related psychological distress across Australia were randomly allocated to either a 6-session group-based programme based on positive affect training (n=87) or enhanced usual care (EUC, n=87). Primary outcome was total score on the Hospital Anxiety and Depression Scale-anxiety and depression subscales assessed at baseline, 1-week post-treatment, 3 months (primary outcome time point) as well as secondary outcome measures of suicidality, generalised anxiety disorder, sleep impairment, positive and negative mood and COVID-19-related stress.

FINDINGS

Between 20 September 2020 and 16 September 2021, 174 participants were enrolled into the trial. Relative to EUC, at 3-month follow-up the intervention led to greater reduction on depression (mean difference 1.2 (95% CI 0.4 to 1.9)), p=0.003), with a moderate effect size (0.5 (95% CI 0.2 to 0.9)). There were also greater reduction of suicidality and improvement in quality of life. There were no differences in anxiety, generalised anxiety, anhedonia, sleep impairment, positive or negative mood or COVID-19 concerns.

CONCLUSIONS

This intervention was able to reduce depression and suicidality during adverse experiences when rewarding events were diminished, such as pandemics.

CLINICAL IMPLICATIONS

Strategies to improve positive affect may be useful to reduce mental health issues.

The Effect of Herbal Medicine on Suicidal Behavior: A Protocol for Systematic Review and Meta-Analysis

Suicide is an important social and medical problem worldwide, including in countries that use traditional East Asian medicine (TEAM). Herbal medicine (HM) has been reported to be effective against several suicide-related conditions. This systematic review aimed to investigate the efficacy and safety of HM in reducing suicidal behavior including suicidal ideation, attempts, or completed suicide. We conduct a comprehensive search in 15 electronic bibliographic databases from inception to September 2022. All types of prospective clinical studies-including randomized controlled clinical trials (RCTs)-involving HM without or with routine care are included. The primary outcomes of this review are validated measures of suicidal ideation including the Beck scale for suicidal ideation. The revised Cochrane's risk of bias tool and other tools including the ROBANS-II tool are used to assess the methodological quality of RCTs and non-RCTs, respectively. A meta-analysis is performed using RevMan 5.4 in cases of homogeneous data from controlled studies. The results of the systematic review provide high-quality evidence to determine the efficacy and safety of HM for suicidal behavior. Our findings are informative for clinicians, policymakers, and researchers, aimed at reducing suicide rates, especially in countries that use TEAM.
