Why women are less likely than men to commit suicide

Practice Guidelines in the Assessment and Treatment of Depression and Suicidality in Adolescent Females

STUDY OBJECTIVE

Suicide is a leading cause of death for adolescents. Medical professionals are increasingly being asked to screen for depressive symptoms and suicidal ideation with little training. The purpose of this paper is to review factors related to suicidal thoughts and actions, assessment of symptoms, and initial suggestions for treatment for medical providers.

METHODS

A literature review of risk and resilience factors, assessment measures, and treatment options for depression and suicidal ideation and behavior in adolescent females was conducted.

RESULTS

Given the higher risk of suicidal thoughts and depressive symptoms in adolescent females, accurate and thorough assessment of symptoms is recommended.

CONCLUSION

Medical providers should be aware of symptoms related to depression and suicidal ideation in order to provide more effective assessments. Recommendations for brief assessment measures that can be used in the clinic and possible first line treatments are provided.

New pharmacotherapies to tackle the unmet needs in bipolar disorder: a focus on acute suicidality

INTRODUCTION

Suicidal behavior is relatively frequent in patients with bipolar disorder (BD) and constitutes their most frequent cause of death. Suicide rates remain high in patients with BD despite adherence to guidelines recommending lithium as first line, and/or antidepressants, antipsychotics, psychotherapy, psychosocial interventions, and electroconvulsive therapy. Hence the need to identify more effective and rapid anti-suicide interventions.

AREAS COVERED

To tackle the unmet needs of pharmacotherapy, we investigated the PubMed database on 24-25 January 2024 using strategies like ('acute suicid*'[ti] OR 'suicide crisis syndrome' OR 'acute suicidal affective disturbance') AND (lithium[ti] OR clozapine[ti]), which obtained 3 results, and ('acute suicid*'[ti] OR 'suicide crisis syndrome' OR 'acute suicidal affective disturbance') AND (ketamine[ti] OR esketamine[ti] OR NMDA[ti] OR glutamat*[ti]), which yielded 14 results. We explored glutamatergic abnormalities in BD and suicide and found alterations in both. The noncompetitive NMDS antagonist ketamine and its S-enantiomer esketamine reportedly decrease acute suicidality.

EXPERT OPINION

Intranasal esketamine or subcutaneous ketamine, single-bolus or intravenous, and possibly other glutamate receptor modulators may improve suicidal behavior in patients with unipolar and bipolar depression. This may be achieved through prompt remodulation of glutamate activity. The correct use of glutamatergic modulators could reduce acute suicidality and mortality in patients with BD.

Predicting Acute Changes in Suicidal Ideation and Planning: A Longitudinal Study of Symptom Mediators and the Role of the Menstrual Cycle in Female Psychiatric Outpatients With Suicidality

OBJECTIVE

Cross-sectional and preliminary longitudinal findings suggest that cyclical ovarian hormone fluctuations influence acute suicide risk. The authors provide the first analyses in females with suicidality to investigate which daily symptoms covary with suicidal ideation and planning thoughts, the role of the menstrual cycle in daily symptom variation, how daily fluctuations in symptoms mediate the menstrual cycle-suicidality relationship, and how these associations vary across individuals.

METHODS

Naturally cycling psychiatric outpatients (N=119) with past-month suicidal ideation provided daily ratings of psychiatric symptoms (depression, hopelessness, anxiety, feeling overwhelmed, agitation, anhedonia, worthlessness, rejection sensitivity, anger, perceived burdensomeness, and interpersonal conflict), suicidal ideation, and suicidal planning across at least one menstrual cycle. Symptom ratings were decomposed into trait (person-centered mean) and state (daily person-centered mean deviation) components. Five cycle phases were identified in relation to menses onset and ovulation (surge in urine luteinizing hormone level). Hypotheses were tested in multilevel structural equation models.

RESULTS

Nearly all psychiatric symptoms covaried with fluctuations in daily suicidal ideation, and a limited set of symptoms (depression, hopelessness, rejection sensitivity, and perceived burdensomeness) predicted within-person increases in suicidal planning. Many patients demonstrated perimenstrual worsening of psychiatric symptoms, suicidal ideation, and suicidal planning. Depressive symptoms (depression, hopelessness, perceived burdensomeness, and anhedonia) were the most robust statistical mediators predicting perimenstrual exacerbation of suicidality.

CONCLUSIONS

Research on the menstrual cycle and suicide has been limited historically by small, cross-sectional samples. This study provides the first evidence that measuring day-to-day correlates of suicidality in a large transdiagnostic sample of females with suicidal ideation can contribute to understanding the pathways by which the menstrual cycle influences acute suicide risk.

Suicide attempts and the factors that lead to suicidal ideation: A 3-year analysis

OBJECTIVE

We explored the epidemiological characteristics of suicide attempts and identified suicide trends and associated factors.

METHODS

This retrospective, cross-sectional, observational, and single-center study included consecutive 412 patients who were admitted to Emergency Department for follow-up and treatment after a suicide attempt between June 2019 and June 2022. We assessed patient demographics, suicidal behavior, previous suicide attempts, psychiatric disorders, drug use, visits to the psychiatry clinic within the past 6 months, the persistence of suicidal ideation, and clinical outcomes.

RESULTS

The study population consisted of 259 females (62.86%) and 153 males (37.14%), with a mean age of 29.50±11.51 (range: 13-72) years. Females attempted suicide more often than males, but suicide completion was more common in males. Overall, 79.37% (n=327) of the suicide attempters were aged <40 years and most were 20-29 years old (n=147, 35.68%). Non-fatal suicide attempts were more common in single, unemployed, and poorly educated individuals, but this was not the case for suicide completers. However, there was no significant difference in marital status, education, and occupation among suicide completers. Drug poisoning was the major form of suicide attempt (n=345, 83.74%). Mental disorders, family or relationship conflicts, and separation from a partner were common causes of suicidal ideation. Patient numbers were particularly high in the autumn (i.e., September), and at night.

CONCLUSION

Females, young adults, singletons, the unemployed, and individuals with psychiatric disorders and low education levels are more likely to attempt suicide, particularly during hours when they are likely to be alone.

Factors associated with suicide/self-inflicted injuries among women aged 18-65 years in the United States: A 13-year retrospective analysis of the National Inpatient Sample database

BACKGROUND

Suicide is a significant cause of mortality in the United States, accounting for 14.5 deaths/100,000. Although there are data on gender disparity in suicide/self-inflicted injury rates in the United States, few studies have examined the factors associated with suicide/self-inflicted injury in females.

OBJECTIVE

To determine factors associated with suicide/self-inflicted injuries among women aged 18-65 years in the United States.

METHODS

Hospitalizations for suicide or self-inflicted injuries were identified using the National Inpatient Sample database from 2003-2015 using sample weights to generate national estimates. Independent predictors of suicide/self-inflicted injuries were identified using multivariable regression models. Interaction term analysis to identify the interaction between race/ethnicity and income were conducted.

RESULTS

There were 1,031,693 adult women hospitalizations in the U.S. with a primary diagnosis of suicide/self-inflicted injury in the study period. The highest suicide/self-inflicted injury risk was among women aged 31-45years (OR = 1.23, CI = 1.19-1.27, p < 0.05). Blacks in the highest income strata had a 20% increase in the odds of suicide/self-inflicted injury compared to Whites in the lowest socioeconomic strata (OR = 1.20, CI = 1.05-1.37, p <0.05). Intimate partner violence increased suicide/self-inflicted injury risk 6-fold (OR = 5.77, CI = 5.01-6.65, p < 0.05).

CONCLUSION

Suicide risk is among women aged 31-45 years, higher earning Black women, intimate partner violence victims, uninsured, and current smokers. Interventions and policies that reduce smoking, prevents intimate partner violence, addresses racial discrimination and bias, and provides universal health coverage are needed to prevent excess mortality from suicide deaths.

Comparative Epidemiology of Attempted and Fatal Suicide in a Defined Catchment Area in Israel

BACKGROUND

Both attempted and fatal suicides are important public health issues and the relationship between these behaviors has great relevance to clinical practice.

AIMS

To determine how the epidemiology of attempted and fatal suicide relate to each other over time.

METHOD

In an 18-year period consecutive admissions for suicide attempts (n = 4,645) to the emergency room of the central hospital of a well-defined catchment area were assessed using a structured interview. Data were compared with records of 425 fatal suicides from the same catchment area.

RESULTS

The relative rates of attempted and fatal suicide changed over time independent of both age and gender up to age 64. Rates of suicide and attempted suicide did not correlate over time in this age group. This was not true for the over 65 age group where attempted suicide and fatal suicide were significantly correlated over time in both men and women.

CONCLUSIONS

In subjects over 65 attempted suicide is highly associated with eventual suicide. This relationship is much less clear in younger age groups. Thus age of attempt is of great importance when considering the prognostic import of a suicide attempt.

Association between unmet healthcare needs and suicidal behaviors among the Korean population

OBJECTIVE

Suicide is an important public health concern. In South Korea, suicide rates have steadily risen over the past two decades. Unfortunately, there is a dearth of literature on the effects of unmet healthcare needs on suicide. Therefore, this study aimed to analyze the relationship between unmet healthcare needs and suicidal behaviors (suicidal ideation, plans, and attempts).

METHOD

This study analyzed data from 27,498 participants assessed by the Korea National Health and Nutrition Examination Survey conducted between 2016 and 2020. Logistic regression was used to evaluate the relationship between unmet healthcare needs and suicidal behaviors, while controlling for age, sex, education, household income, occupation, smoking, obesity, and alcohol consumption.

RESULTS

Adjusted odds ratios (95% confidence interval) were significantly higher in participants who experienced unmet healthcare needs [suicidal ideation: 2.31 (1.84-2.90); suicidal planning: 2.23 (1.75-2.85); and suicidal attempts: 1.92 (1.27-2.87)]. After stratifying for sex and depression, this trend was maintained in male participants and those without a depression diagnosis.

CONCLUSIONS

This study analyzed the relationship between unmet healthcare needs and suicidal behavior. Further studies using data sources that include more detailed information on suicide and somatic symptoms are required.

Drug self-poisoning in adolescents: A report of 267 cases

Introduction

The current study aims at describing a sample of adolescents admitted to a tertiary referral pediatric hospital for drug self-poisoning and to identify variables that could explain and predict a higher severity of intoxication.

Methods

We retrospectively reviewed the cases of drug self-poisoning in adolescents admitted to the Bambino Gesù Children's Hospital between January 2014 and June 2022 requiring consultation by the local Pediatric Poison Control Center (PPCC). We reported the type and class of drug ingested and correlated the clinical characteristics of the patients with their Poison Severity Score.

Results

The data of 267 patients were reported. Most patients were female (85.8 %), with a median age of 15.8 years at presentation. Half of the patients were symptomatic at admission (44.2 %), and most had at least one psychiatric comorbidity (71.1 %). Most patients were hospitalized (79.6 %), 16.6 % of cases required antidote administration and a minority required intensive care. Most patients received a PSS score of 0 (59.6 %). The most frequently ingested drug was acetaminophen (28.1 %) followed by ibuprofen (10.1 %) and aripiprazole (10.1 %). Antipsychotics as a class were the most abused drugs (33.1 %). The correlation of clinical variables with the PSS showed that older and male patients were more prone to be severely intoxicated.

Conclusions

This single-center study identifies the most commonly ingested drugs in a large sample of adolescents with voluntary drug self-poisoning, also showing that older and male patients are more susceptible to severe intoxication.

Association of Human Papillomavirus Status With Suicide Risk Among Patients With Head and Neck Cancer

Importance

Human papillomavirus (HPV) is strongly associated with head and neck cancer, and HPV status is considered a prognostic factor. Being a sexually transmitted infection, HPV-related cancers may have greater risk of stigma and psychological distress; however, the potential association of HPV-positive status with psychosocial outcomes, such as suicide, is understudied in head and neck cancer.

Objective

To investigate the association between HPV tumor status and suicide risk among patients with head and neck cancer.

Design, Setting, and Participants

This population-based retrospective cohort study included adult patients with clinically confirmed cases of head and neck cancer based on HPV tumor status from the Surveillance, Epidemiology, and End Results database from January 1, 2000, to December 31, 2018. Data analysis was conducted from February 1 to July 22, 2022.

Main Outcomes and Measures

The outcome of interest was death by suicide. Primary measure was HPV status of tumor site, dichotomized as positive or negative. Covariates included age, race, ethnicity, marital status, cancer stage at presentation, treatment modality, and type of residence. Cumulative risk of suicide among patients with HPV-positive and HPV-negative head and neck cancer was assessed using Fine and Gray competing risk models.

Results

Of 60 361 participants, the mean (SD) age was 61.2 (13.65) years, and 17 036 (28.2%) were women; there were 347 (0.6%) American Indian, 4369 (7.2%) Asian, 5226 (8.7%) Black, 414 (0.7%) Native Hawaiian or Other Pacific Islander, and 49 187 (81.5%) White individuals. A competing risk analysis showed a significant difference in the cumulative incidence of suicide between HPV-positive cancers (5-year suicide-specific mortality, 0.43%; 95% CI, 0.33%-0.55%) and HPV-negative cancers (5-year suicide-specific mortality, 0.24%; 95% CI, 0.19%-0.29%). Tumor status that was HPV positive was associated with increased suicide risk in the unadjusted model (hazard ratio [HR], 1.76; 95% CI, 1.28-2.40), but not the fully adjusted model (adjusted HR, 1.18; 95% CI, 0.79-1.79). Among people with oropharyngeal cancer only, HPV status was associated with increased suicide risk, but the width of the confidence interval prevented definitive conclusion (adjusted HR, 1.61; 95% CI 0.88-2.94).

Conclusions and Relevance

The results of this cohort study suggest that patients with HPV-positive head and neck cancer have similar risk of suicide as patients with HPV-negative cancer, despite differences in overall prognosis. Early mental health interventions may be associated with reduced suicide risk in all patients with head and neck cancer and should be assessed in future work.

Contextualizing Black Women's Mental Health in the Twenty-First Century: Gendered Racism and Suicide-Related Behavior

Despite predictions from the Black-White and gender paradoxes in suicide risk, there has been a recent growth in suicide rates among Black women and girls that requires special attention from social and behavioral researchers. In this review, we demonstrate how and why an intersectional framework is needed to understand and contextualize Black women's mental health and suicide risk. To begin, we outline data and existing literature on Black women's mental health outcomes. Next, we provide insights from intersectional and Black feminist scholars on the uniqueness of Black womanhood and the necessity of centering racism and sexism in studies of Black women. Third, we present clear links between mental health, gendered racism experienced by Black women, and the Strong Black Woman schema which they adopt to navigate society. Fourth, and finally, we discuss practical and scholarly applications for this work. To this end, this research agenda is about advocating for the consideration of psychosocial and sociocultural factors in practice and research on suicide-related behavior.

The role of clinical and Personological features in predicting high lethality suicide attempts: A study among mood disorder patients

Suicidal attempts (SA) represent heterogeneous behaviours ranging in their seriousness from fatal and near-fatal (high-lethality) cases to those that do not require medical attention (low lethality). These considerations stress the need to identify high-risk individuals for high lethality SA in order to target suicide preventive interventions. The present study aims at evaluating the role of sociodemographic and clinical variables and examining personality pathological features in predicting high lethality SA. The sample was composed by 94 patients who were consecutively admitted to the Mood Disorders Unit of the San Raffaele Turro Hospital in Milan. The results of binary logistic regression analyses showed that previous SA and current suicide ideation play a role in predicting serious SA. Considering the DSM-5 personality dysfunctional domains assessed by the Personality Inventory for DSM-5, our logistic regression analyses suggested that high lethality SA was associated with Detachment PID-5 domain. Finally, binary hierarchical regression analysis showed that Detachment domain remained a significant predictor of serious SA over and above the effect of previous SA and suicide ideation. As a whole, our results highlight the importance of a multidimensional approach to develop adequate assessment, effective treatments and prevention of high lethality SA risk.

Is Lethality Different between Males and Females? Clinical and Gender Differences in Inpatient Suicide Attempters

According to the gender paradox in suicidology, an important sex difference has been reported with a preponderance of females in nonfatal suicidal behavior and a preponderance of males in completed suicide. Furthermore, females and males present different risk factors for suicide. The present study explored possible clinical differences between male and female psychiatric inpatients who had recently attempted suicide. The study included 177 adult inpatients hospitalized following a suicide attempt at the University Psychiatric Clinic, Sant'Andrea Hospital, Sapienza University of Rome. Clinical features assessed included psychiatric diagnosis, method and lethality of suicide attempts using the Risk/Rescue Rating Scale, the history of suicide attempts, age at onset of psychiatric illness, the presence of substance or alcohol use, and the length of stay. The results found that males and females differed in the method used for the suicide attempt, the scores for risk and rescue, and the length of hospitalization post-suicide attempt. In conclusion, identifying gender characteristics of patients at higher risk of suicide is important for implementing specific suicide prevention strategies and reducing the risk of future suicidal behavior in psychiatric inpatients.

Psychosocial and Psychiatric Factors Associated with Expected Fatality during Suicide Attempt in Men and Women

BACKGROUND: Differential factors that influence intention and subjectively perceived fatality during non-fatal suicidal acts amongst men and women have rarely been explored in the extant literature. Exploring these factors may help to understand how they influence medical outcomes and may also be used in a post-crisis counselling. This study aims to assess factors influencing intent in relation to expected fatality during suicidal acts in men and women. METHOD: In the current study, 433 individuals who attempted suicide (age 24.890.98 years, male/female ratio=1.29) were surveyed using the WHO-5 Well-Being Index, Beck Depression Inventory, Beck Suicide Intent Scale, Plutchik Feelings and Acts of Violence Scale, and Spielberger State/Trait Anger Scale. Life stress was evaluated as an accumulation of negative life events, whilst psychiatric disorders were assessed using CIDI 2.1 inventory. RESULTS: It was found that the higher expected fatality was associated with higher suicide intention scores, whereas the medical severity of attempts and violent/non-violent attempts distribution did not differ between groups. Although there was no difference in suicide intent scores and medical severity between men and women, men demonstrated a 2.43.5 times higher proportion of violent attempts, depending on the group. Higher perceived fatality was associated with lower general well-being, higher depression and violence, hopelessness, and total life stress in men, whereas among women higher perceived fatality was only associated with total life stress. Moreover, in men and women, higher intent and expected fatality was associated with a differential set of negative life events that occurred during childhood. The prevalence of mental health disturbances in the entire sample was about 50% and equally distributed among men and women. However, addictions prevailed among men, while neurotic and stress-related disorders were more common among women. Among those who expected more fatality the number of people with diagnoses and comorbidity was higher, especially in men. CONCLUSION: There is a difference in risk factors for expected fatality and intent in men and women attempting suicide, which may not necessarily result in severe medical outcomes but may help during the post-crisis counseling of suicide attempters. Expected fatality deserves more attention as a component of general intent. An in-depth study of this phenomenon may help to understand motives of men and women attempting suicide and help prevent future suicidal attempts.

Sex-based differences in the predisposing factors of overdose: A retrospective study

Drug overdose is one of the common events encountered in the emergency department (ED). The aim of the present study was to investigate the sex difference and predisposing factors of overdose in the ED. Data of 299 patients with self-poisoning reported at our poison center from January 2018 to August 2019 were retrospectively analyzed. Study cases categorized using the International Classification of Diseases, Tenth Revision coding system, which include codes T36 to T50, were selected. Data were collected including Glasgow Coma Scale scores and vital signs upon arrival (including body temperature, heart rate, systolic blood pressure, and diastolic blood pressure, sex, age, marital status, arrival time, season on admission, previous suicide attempts, psychiatric history, related comorbidities, recent arguments, categories of overdose with or without concurrent ethanol use, length of hospital stay, and survival to discharge) were analyzed. The top three types of substances that were frequently involved in drug overdose were benzodiazepine (42.9%), mixed medications (32.1%), and acetaminophen (6.1%). The 196 enrolled patients were aged 14 to 92 years (mean ± standard deviation, 39.2±18.3), and of these patients, male intentional overdose patients were 8.1 years older than their female counterparts (45.3±19.5 vs. 37.2±17.5, respectively; P<0.05). Most intentional overdose cases occurred during the spring season (n=63, 32.1%), especially in male patients (n=28, 57.1%; P<0.001). Approximately 11.2% (22/196) and 2% (4/196) of the total patients were admitted to the Toxicology ward and intensive care units, respectively. The length of hospital stay was 2±4.1 days. In summary, it is suggested that physicians notify the suicide prevention centers to be on alert for middle-aged men who are facing conflicts, especially during the spring season.

Assessment of Contributing Factors and Treatment Practices for Therapeutic Efficacy and Drug-Related Problems in Suicidal Psychotic Patients

Suicide, a deliberate act of self-harm with the intention to die, is an emerging health concern but, unfortunately, the most under-researched subject in Pakistan, especially in Khyber Pukhtunkhwa (KPK). In this study, we aimed to identify risk factors that can be associated with suicidal behavior (SB) and to evaluate the prevailing treatment practices for therapeutic efficacy and drug-related problems (DRPs) in psychotic patients among the local population of KPK. A prospective, multicenter study was conducted for suicidal cases admitted to the study centers by randomized sampling. Socio-demographics and data on suicidal behavior were assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS), socioeconomic condition by Kuppuswamy socioeconomic scale (KSES) and treatment adherence by Morisky Medication-Taking Adherence Scale (MMAS-4). Drug-related problems and the therapeutic efficacy of prevailing treatment practices were assessed at baseline and follow-up after 3 months of treatment provided. Regarding suicidality (N = 128), females reported more ideations (63.1%), while males witnessed more suicidal behavior (66.6%, p < 0.001). Suicide attempters were mostly married (55.6%, p < 0.002); highly educated (53.9%, p = 0.004); dissatisfied with their life and had a previous history (p < 0.5) of suicide attempt (SA) (20.6%), self-injurious behavior (SIB) (39.7%) and interrupted (IA) or aborted attempts (AA) (22.2%). A greater improvement was observed in patients receiving combination therapy (p = 0.001) than pharmacotherapy (p = 0.006) or psychotherapy (p = 0.183), alone. DRPs were also detected, including drug-selection problems (17.88%), dose-related problems (20.64%), potential drug−drug interactions (24.31%), adverse drug reactions (11.46%) and other problems like inadequate education and counseling (21.55%). Furthermore, it was also found that psychotic patients with suicidal ideations (SI) were significantly (p = 0.01) more adherent to the treatment as compared to those with suicidal attempts. We concluded that suicide attempters differed significantly from patients with suicidal ideations in psychotic patients and presented with peculiar characteristics regarding socio-demographic factors. A combination of therapies and adherence to the treatment provided better outcomes, and targeted interventions are warranted to address drug-related problems.

Prevalence of lifetime self-injurious thoughts and behaviors in a global sample of 599 patients reporting prospectively confirmed diagnosis with premenstrual dysphoric disorder

BACKGROUND

Suicide is the second leading cause of death among Americans ages 10 to 34, with alarming recent increases in suicide rates among those assigned female at birth. A large body of evidence points to menstrual cycle influences on self-injurious thoughts and behaviors (STBs), suggesting that neurobiological hormone sensitivities, such as in premenstrual dysphoric disorder (PMDD), may drive suicide risk in females. However, existing studies of STBs in PMDD use cross-sectional self-report measures of PMDD with poor validity. As a first step to establish accurate prevalence rates of STBs in PMDD, we examined the lifetime prevalence of STBs in a large global survey of patients reporting a diagnosis of PMDD based on daily ratings.

METHOD

Individuals with self-reported PMDD symptoms were invited to an online survey through online support groups for PMDD and social media posts from PMDD awareness accounts. Participants reported demographics, whether they had been diagnosed with PMDD by a healthcare provider using daily ratings, STBs using the Columbia Suicide Severity Rating Scale, and history of lifetime comorbid psychiatric diagnoses.

RESULTS

Of 2,689 survey completers, 599 (23%) reported a diagnosis with PMDD based on two months of daily ratings and were included in analyses. We observed high rates of lifetime active suicidal ideation (72%), planning (49%), intent (42%), preparing for an attempt (40%), and attempt (34%), as well as non-suicidal self-injury (51%). The majority (70%) of the sample reported at least one lifetime comorbid psychiatric diagnosis. Predictors of lifetime active suicidal ideation included nulliparity, low-to-moderate (vs. high) income, and history of diagnosis with major depression or post-traumatic stress disorder. Predictors of lifetime attempts among those reporting lifetime active ideation included older age, nulliparity, lower income, and history of diagnosis with post-traumatic stress disorder or borderline personality disorder.

CONCLUSIONS

These data indicate high rates of STBs among those reporting prospective diagnosis of PMDD and highlight the need for prospective research on mechanisms and prevention of STBs in PMDD. Clinical practice guidelines for PMDD should accommodate comorbidities and recommend frequent screenings for STB risk. STBs should be considered for inclusion in future iterations of the DSM PMDD diagnostic criteria.

Reasons for Suicide During the COVID-19 Pandemic in Japan

IMPORTANCE

Although the suicide rate in Japan increased during the COVID-19 pandemic, the reasons for suicide have yet to be comprehensively investigated.

OBJECTIVE

To assess which reasons for suicide had rates that exceeded the expected number of suicide deaths for that reason during the COVID-19 pandemic.

DESIGN, SETTING, AND PARTICIPANTS

This national, population-based cross-sectional study of data on suicides gathered by the Ministry of Health, Labor, and Welfare from January 2020 to May 2021 used a times-series analysis on the numbers of reason-identified suicides. Data of decedents were recorded by the National Police Agency and compiled by the Ministry of Health, Labor, and Welfare.

EXPOSURE

For category analysis, we compared data from January 2020 to May 2021 with data from December 2014 to June 2020. For subcategory analysis, data from January 2020 to May 2021 were compared with data from January 2019 to June 2020.

MAIN OUTCOMES AND MEASURES

The main outcome was the monthly excess suicide rate, ie, the difference between the observed number of monthly suicide deaths and the upper bound of the 1-sided 95% CI for the expected number of suicide deaths in that month. Reasons for suicide were categorized into family, health, economy, work, relationships, school, and others, which were further divided into 52 subcategories. A quasi-Poisson regression model was used to estimate the expected number of monthly suicides. Individual regression models were used for each of the 7 categories, 52 subcategories, men, women, and both genders.

RESULTS

From the 29 938 suicides (9984 [33.3%] women; 1093 [3.7%] aged <20 years; 3147 [10.5%] aged >80 years), there were 21 027 reason-identified suicides (7415 [35.3%] women). For both genders, all categories indicated monthly excess suicide rates, except for school in men. October 2020 had the highest excess suicide rates for all cases (observed, 1577; upper bound of 95% CI for expected number of suicides, 1254; 25.8% greater). In men, the highest monthly excess suicide rate was 24.3% for the other category in August 2020 (observed, 87; upper bound of 95% CI for expected number, 70); in women, it was 85.7% for school in August 2020 (observed, 26; upper bound of 95% CI for expected number, 14).

CONCLUSIONS AND RELEVANCE

In this study, observed suicides corresponding to all 7 categories of reasons exceeded the monthly estimates (based on data from before or during the COVID-19 pandemic), except for school-related reasons in men. This study can be used as a basis for developing intervention programs for suicide prevention.

Large-Scale Transcriptomics Studies Provide Insight Into Sex Differences in Depression

Major depressive disorder (MDD) is a leading cause of disability, affecting more than 300 million people worldwide. We first review the well-known sex difference in incidence of MDD, with women being twice as likely to be diagnosed as men, and briefly summarize how the impact of MDD varies between men and women, with sex differences in symptoms, severity, and antidepressant drug response. We then attempt to deconstruct the biological bases for MDD and discuss implications for sex differences research. Next, we review findings from human postmortem studies, both from selected candidate gene studies and from well-powered, unbiased transcriptomics studies, which suggest distinct, and possibly opposite, molecular changes in the brains of depressed men and women. We then discuss inherent challenges of research on the human postmortem brain and suggest paths forward that rely on thoughtful cohort design. Although studies indicate that circulating gonadal hormones might underlie the observed sex differences in MDD, we discuss how additional sex-specific factors, such as genetic sex and developmental exposure to gonadal hormones, may also contribute to altered vulnerability, and we highlight various nuances that we believe should be considered when determining mechanisms underlying observed sex differences. Altogether, this review highlights not only how various sex-specific factors might influence susceptibility or resilience to depression, but also how those sex-specific factors might result in divergent pathology in men and women.

The importance of suicide risk assessment in patients affected by neurofibromatosis

OBJECTIVE

Neurofibromatosis 1 (NF1) is a chronic medical disease that often presents with psychiatric disorders. We investigated suicidal ideation in NF1 patients compared to healthy controls. We also evaluated whether hopelessness, depressive symptoms and perceived disability may mediate suicidal ideation in patients with NF1.

METHODS

We enrolled 60 patients with NF1 and 50 healthy controls with no history of NF1. Patients underwent a full psychiatric evaluation. Psychiatric diagnosis was made according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria. Patients and controls underwent a series of psychometric measures, namely the Columbia Suicide Severity Rating Scale, the Beck Hopelessness Scale, the Italian Perceived Disability Scale and the Beck Depression Inventory.

RESULTS

Suicidal ideation was significantly higher in patients with NF1 (45%) than in controls (10%). Patients also presented more severe perceived disability and hopelessness and more frequent psychiatric disorders than controls. Multivariable logistic regression analysis showed that perceived disability was independently associated with the presence of suicidal ideation in patients with NF1.

CONCLUSIONS

In conclusion, our results showed that suicidal ideation was present in almost half of patients with NF1, suggesting the importance of suicide assessment in these patients.Key pointsPatients with NF1 have an increased suicide ideation when compared to healthy controlsIncreased suicidal ideation correlates with perceived disability, but not with the presence of psychiatric disordersAssessment of suicidal ideation should be performed in patients with NF1.

Gender differences in suicide-related communication of young suicide victims

OBJECTIVES

There is limited insight into gender differences in suicide-related communication (SRC) in youths. SRC is defined as "the act of conveying one's own suicide ideation, intent or behaviours to another person". Increasing our understanding of SRC in youths will enable us to recognize and specify needs of female versus male youths. The current study explores SRC in a sample of Dutch suicide victims aged under 20 and examines gender differences.

METHODS

Interview data from a psychological autopsy study of 35 youths who died by suicide in the Netherlands in 2017 were analysed. Qualitative analyses were performed to examine explicit SRC throughout the youths' lives and implicit SRC during the last months prior to suicide. We employed the Constant Comparative Method to explore patterns in the debut, form, frequency, medium, content, type of recipient, and SRC in the last months prior to suicide death.

RESULTS

We identified commonalities in the SRC of youths, including the content of suicide notes and an emphasis on suicide method and preparation in the last months. Girls, however, had an earlier debut of SRC, a higher frequency of explicit SRC, and more often directed SRC towards varied types of recipients compared to boys. Moreover, SRC of girls seemed focused on coping and achieving support from others more than SRC of boys. The SRC of boys in comparison to girls was often ambiguous or diluted by "humorous" connotations.

CONCLUSION

Unique patterns in SRC of boys and girls posed corresponding challenges for next of kin to interpret communications and respond adequately to SRC. The early debut of girls' SRC highlights the importance of early screening and prevention efforts in girls, while the late debut and ambiguity in boys' SRC implores professionals and next of kin to encourage young males to be unequivocal about suicide ideation or intent.

Suicide in Nigeria: observations from the content analysis of newspapers

Background

Suicide is a global public health problem and Nigeria is one of the epicentres of suicide in the world. However, there is a dearth of research exploring the epidemiological aspects of suicide in Nigeria.

Aim

To examine the demographic information and precipitating events for suicides in Nigeria by analysing the contents of newspaper reports of suicide.

Methods

We searched, collected, and analysed published news reports about suicide from 10 English newspapers in Nigeria. A total of 350 suicide reports were assessed between January 2010 and December 2019 after screening and sorting.

Results

The mean (SD) age of the reported cases was 36.33 (15.48) years. Majority of the reported cases were male (80.6%), married (51.8%), students (33.6%), living in a semi-urban area (40.3%) and among the age group of 25–34 (25.3%). Hanging (48.6%) and poisoning (32.2%) were the most commonly reported methods of suicide. Financial constraints and marital conflicts were most commonly assumed precipitating factors.

Conclusion

This study suggests that being male, married, or living in semi-urban areas are associated with suicide in Nigeria. Further community-based studies are warranted to generalise the findings and adopt appropriate preventive strategies.

Suicidal ideation in early-onset Parkinson's disease

OBJECTIVE

Patients with early-onset Parkinson's disease (EOPD) often suffer from more frequent depression than those with late-onset Parkinson's disease (LOPD). However, the clinical characteristics of suicidal ideation (SI) in EOPD remains unknown. This study aimed to explore the prevalence, related factors, and predictive factors of SI in EOPD patients as well as comparison of the prevalence in LOPD patients.

METHODS

We conducted a case-control, cross-sectional, and longitudinal study. Propensity score matching (PSM) was used to balance the characteristics between EOPD (N = 577) and LOPD patients (N = 2973). The diagnosis of SI was based on the assessment of the Beck Depression Inventory (BDI). EOPD patients with a disease duration < 5 years (N = 96) were prospectively followed-up for exploring the predictors for the development of SI. Two forward binary logistic regression models were respectively used to explore the associated and predictive factors of SI.

RESULTS

After PSM, EOPD patients showed significantly higher prevalence of SI than LOPD patients (22.0 vs. 13.3%, P < 0.001). Twenty EOPD patients (20.8%) developed SI and none of them reported suicidal behaviors after a median of 2.7 (IQR = 1.6-4.1) years. Depression, dyskinesia, non-smoking, lower education, and higher Non-Motor Symptoms Scale (NMSS) score were independently associated with the presence of SI. Depression at baseline was the only independent risk factor for the future occurrence of SI.

CONCLUSIONS

Our study highlights the necessity to screen SI in patients with EOPD especially for those with depression.

Unrelenting Depression and Suicidality in Women with Autistic Traits

Understanding the cognitive and emotional mechanisms that link autistic traits and risk for suicide is a vital next step for research and clinical practice. This study included a broad sample of adult women (n = 74) who report finding social situations confusing and/or exhausting, and who score high on measures of autistic traits. Regardless of autism diagnostic status, these women reported high rates of suicidal thoughts and behaviors. Depression symptoms were more associated with suicidality than were autistic trait measures of social communication. Measures of neurotypical "imagination" and of repetitive behavior likewise were associated with suicidality risk. Simultaneously feeling sad and feeling stuck or unable to imagine alternate strategies, may uniquely increase suicide risk in autism.

Excess Mortality From Suicide During the Early COVID-19 Pandemic Period in Japan: A Time-Series Modeling Before the Pandemic

Background

Suicide amidst the coronavirus disease (COVID-19) pandemic is an important issue. In Japan, the number of suicides in April 2020 decreased by nearly 20% from that in 2019. To assess the impact of an infectious disease pandemic, excess mortality is often discussed. Our main purpose was evaluating excess mortality from suicide in Japan during the early pandemic period.

Methods

We used data on suicides collected by the National Police Agency of Japan until June 2020. We estimated excess mortality during the early pandemic period (March–June 2020) using a time-series model of the number of suicides before the pandemic. A quasi-Poisson model was employed for the estimation. We evaluated excess mortalities by the categories of age and sex, and by prefecture.

Results

No significant excess mortality was observed throughout the early pandemic; instead, a downward trend in the number of suicides for both sexes was noted. For males, negative values of excess mortalities below the lower bound of the 95% prediction interval were observed in April and May. All numbers of females during the period were included in the interval, and the excess mortalities in June were positive and higher than those in April and May. In Tokyo, the number of suicides was below the lower bound throughout the period.

Conclusion

Our results suggest that various changes, such as communication, and social conditions amid the early COVID-19 pandemic induced a decrease in suicides in Japan. However, continuous monitoring is needed to evaluate the long-term effects of the pandemic on suicides.

Trends in the Incidence and Lethality of Suicidal Acts in the United States, 2006 to 2015

Importance

Understanding changes in the incidence rates and lethality of suicidal acts may explain increasing suicide rates.

Objective

To examine trends in the incidence rates and lethality of suicidal acts from 2006 to 2015 among persons aged 10 to 74 years.

Design, Setting, and Participants

This cross-sectional study was conducted from May 2, 2018, to January 30, 2019. Medically treated nonfatal suicide attempts were identified from the 2006 to 2015 Nationwide Inpatient Sample and Nationwide Emergency Department Sample databases. Suicides were identified from the 2006 to 2015 mortality files of the National Vital Statistics System.

Main Outcomes and Measures

The incidence rate of suicidal acts was calculated by dividing the number of total suicidal acts by the US population. Lethality was measured through the case fatality rates (CFRs) of suicidal acts by dividing the number of suicides by the total number of suicidal acts.

Results

A total of 1 222 419 (unweighted) suicidal acts, which included both suicides and nonfatal suicide attempts, were identified from 2006 to 2015. Overall, the incidence rates of total suicidal acts increased 10% from 2006 to 2015 (annual percentage change [APC], 0.8%; 95% CI, 0.3%-1.3%), and the CFRs of suicidal acts increased 13% during the 2006 to 2015 period (APC, 2.3%; 95% CI, 1.3%-3.3%). In subgroup analyses, incidence rates increased by 1.1% (95% CI, 0.6%-1.6%) per year for female individuals during the 2006 to 2015 period but remained stable for male individuals. The CFRs increased for both sexes (APC, 5.0% [95% CI, 3.1%-6.9%] since 2010 for female individuals; 1.6% [95% CI, 0.6%-2.5%] since 2009 for male individuals). Incidence rates increased among adolescents from 2011 to 2015 and among older adults aged 65 to 74 years throughout the 2006 to 2015 period. Conversely, the CFRs increased since 2009 among persons aged 20 to 44 years (APC, 3.7%; 95% CI, 2.5%-5.0%) and since 2012 for those aged 45 to 64 years (APC, 2.7%; 95% CI, 0.0%-5.4%). Persons aged 20 to 44 years and 45 to 64 years experienced increases in suicidal acts by more lethal means, whereas adolescents and older adults aged 65 to 74 years showed increased incidence by all means.

Conclusions and Relevance

This study found increased suicidal acts among female persons, adolescents, and older adults aged 65 to 74 years, implying the need to address emerging or exacerbating suicide risk factors for these populations. The findings on the increased lethality particularly among persons aged 20 to 64 years highlighted the need to reduce access to materials that could be used as lethal means among persons at risk of suicide. These findings on population-level epidemiologic patterns can be used to guide the development of comprehensive suicide prevention strategies.

Age and sex trends for suicide in Brazil between 2000 and 2016

PURPOSE

To evaluate changes in standardized suicide rates in Brazil between 2000 and 2016, stratified by sex and age.

METHODS

Descriptive analyses of data from the Brazilian Mortality Information System were performed.

RESULTS

156,292 suicides were registered in the period, with a standardized rate of 4.82/100,000. The risk for males was 3.81 times higher than for females, without meaningful regional variations. This ratio was 8.2 at the 80+ group. An increase from 2000 to 2016 was demonstrated in nearly all subgroups over the 17, especially men aged 20-39 and women aged 40-59.

CONCLUSIONS

Suicide rates continue to rise in Brazil, especially among young men and middle-aged women. Older men remain exposed to the highest absolute risk.

Suicidal ideation and behavior in US veterans with schizophrenia or bipolar disorder

OBJECTIVE

Using data from a Department of Veterans Affairs study of schizophrenia (SZ) and bipolar I disorder (BP), we evaluated lifetime risks for suicidal ideation and behavior. We were interested in the prevalence and correlates of these outcomes, in populations of patients with severe mental illness (SMI), who have not been compared directly in previous studies despite data on high risk in each group separately.

METHOD

Data were collected on demographic factors, medical and psychiatric comorbidity, cognitive and functional status, and lifetime suicidal ideation or behavior in a study of veterans with SZ (N = 3942) or BP (N = 5414). In-person diagnosis and evaluation, including performance-based assessments of cognition and functional skills, make this study unique compared to studies of completed suicide. Multinomial logistic regression examined how risk factors, including major depression and negative symptoms in SCZ patients, correlated with ideation and behavior.

RESULTS

A lifetime history of suicidal ideation or behavior was reported by a majority of Veterans with SZ (69.9%) or BP (82.3%). Lower risk was found for patients with SZ vs. BP (odds ratio [OR] = 0.82 for ideation; OR = 0.81 for behavior). The highest risk was found for patients with multiple psychiatric comorbidities (OR = 2.61 for ideation; OR = 3.82 for behavior). Clinical factors (e.g., psychiatric comorbidity) contributed more of the variance in the predictive model than demographic factors.

CONCLUSIONS

A history of suicidal ideation or behavior is common among US Veterans with SZ or BP, and specific demographic and clinical attributes correlate with variation in risk. These findings underscore the need for continuous monitoring for suicidal ideation and behavior in veteran populations with SMI, as well as the development of better risk predictions, including genomic factors. Although PTSD is a major current focus in veteran populations, the large number of veterans with SZ or BP and their high suicide risk suggests a greater clinical focus may be warranted.

Women, Femininity, Indirect and Direct Self-Destructiveness. A Review

The aim of this work was to review results of research into direct and indirect self-destructiveness in women. Studied projects covered two populations: individuals who attempted suicide and individuals who did not attempt suicide. The Chronic Self-Destructiveness Scale and Bem Sex Role Inventory were used. Intensity of indirect self-destructiveness is lower in women. A probable explanation of the gender paradox in suicides may be the hypothesis that suicides attempted by men more often end in death as men display stronger indirect self-destructiveness. Masculinity and male sex are factors that predispose to indirect self-destructiveness, while femininity and female sex are factors protecting against it. Gender schema opposite to biological sex is significant to intensity of indirect self-destructiveness.

Suicide Risk in Young Men and Women After Substance Intoxication

This study investigates suicide and overdoses in 1,119 consecutive patients (64% women), 15 to 34 years of age, presenting at the emergency department after self-poisoning from1994 to 2000 and followed regarding death to 2006. Regression and Kaplan-Meier survival analyses were performed for suicide and other causes of death. The patients had about a 60 times higher risk (SMR = 61.95) of death due to suicide and 26 times higher (SMR = 26.47) for all-cause mortality. Men had a nearly 2 times higher risk for suicide than women and half of the suicides occurred during the first 2 years after admission. Poisoning was the most common suicide method and early prevention of self-poisoning is crucial to reducing future deaths.

What's Changed? A Comparison of Army Suicide Surveillance Data to Cases from 1975 to 1982

US Army suicide rates increased significantly in the last decade and have remained high. To inform future research hypotheses, Army suicide surveillance data (2012-2014) were compared to similar Army data for suicides from 1975 to 1982. Preliminary data suggest that suicide rates increased across most demographic groups, but may have decreased among divorced soldiers. Mental health utilization increased over time. Legal problems and physical health problems were identified in a higher percentage of cases in the recent data relative to the 1975-1982 era. Potential implications for suicide prevention are discussed.

"You've Gotta Be That Tough Crust Exterior Man": Depression and Suicide in Rural-Based Men

Suicide rates in Canada are highest among rural men. Drawing on photovoice interviews with 13 women and two men living in a small rural Canadian town who lost a man to suicide, we inductively derived three themes to describe how contextual factors influence rural men's experiences of depression and responses to suicidal thoughts: (a) hiding depression and its cause, (b) manly self-medicating, and (c) mobilizing prevention. Further discussed is how gender relations and ideals of masculinity within rural milieu can inhibit men's acknowledgment of and help seeking for mental illness issues. Participants strongly endorsed a multifaceted approach to the destabilization of dominant ideals of masculinity that likely contribute to depression and suicide in rural men.

Gender differences and psychological factors associated with suicidal ideation among youth in Malaysia

Suicide is a global phenomenon that has been showing an upward trend in recent years. It is the second leading cause of death among youth. Studies on suicidal ideation warrant greater attention, as it leads to suicide attempts and other health risk behaviors. Thus, the objective of this study was to compare gender differences in suicidal ideation and determine the predictors of suicidal ideation among youth. This cross-sectional study was carried out among 232 youths aged between 15 and 25 years from selected urban areas in Malaysia. The results showed that suicidal ideation was higher among male participants compared with female participants. Age was the predictor of suicidal ideation for males, while depression and loss of motivation, as components of hopelessness, were the predictors of suicidal ideation among females. Hence, it is important that professionals conduct early identification tests for suicidality among young people. This will facilitate the early detection of depression and hopelessness, which is important, in order to prevent suicidal behaviors or other problems before these occur.

Socio-demographic characteristics, clinical profile and prevalence of existing mental illness among suicide attempters attending emergency services at two hospitals in Hawassa city, South Ethiopia: a cross-sectional study

BACKGROUND

Suicide is a major public health problem worldwide. It contributes for more than one million deaths each year. Since previous suicidal attempt was considered as the best predictor of future suicide, identifying factors behind suicidal attempt are helpful to design suicide prevention strategies. The aim of this study was to assess socio-demographic characteristics, clinical profile and prevalence of existing mental illness among patients presenting with suicidal attempt to emergency services of general hospitals in South Ethiopia.

METHODS

We conducted a cross-sectional study on patients presenting with complications of suicidal attempt to emergency departments of two general hospitals in Hawassa city from November, 2014 to August, 2015. Data was collected using semi-structured questionnaire which contained socio-demographic and clinical variables. The Mini International Neuropsychiatric Interview version 5 (MINI PLUs) was used to assess the prevalence of existing mental illness among study participants. Data was entered and analyzed using IBM SPSS statistics 21 software package.

RESULTS

A total of 96 individuals were assessed, of whom 56 (58.3%) were females. The mean age of study participants was 21.5 (8.0) years. The majority, 75 (78.1%), of the study participants were aged below 25 years. Ingesting pesticide poisons and corrosive agent were used by the majority to attempt suicide. Mental illness was found in only three (3.1%) of the study participants. Impulsivity (the time between decision to attempt suicide and the actual attempt of less than 5 min) was reported by 30 (31.2%) of the study participants, of whom 18 (60%) were males. Males were found three times more likely to attempt suicide impulsively than women (COR = 3.0, 95% CI 1.2-7.3). Quarreling with family members, facing financial crisis, and having unplanned and unwanted pregnancy were reported by the majority of study participants as immediate reasons to attempt suicide.

CONCLUSIONS

The presence of stressful life events and impulsivity behind suicidal behavior of the younger generation implies that designing suicide prevention strategies for this group is crucial. Moreover, further research is needed to systematically examine the relationship between the presence of mental illness and suicidal attempt with a larger sample size and more robust methodology.

Factors associated with suicidal ideation disclosure: Results from a large population-based study

BACKGROUND

It is crucial for clinicians and researchers to understand the factors associated with the disclosure of suicidal ideation. Describing the characteristics of those who do not disclose their suicidal ideation or who disclose their ideation only to close others, to health professionals or to both may help researchers and clinicians in their preventive efforts to treat persons at risk for suicidal behavior.

METHODS

The sample was drawn from a large cross-sectional survey (n=22,138) on mental health in France. The analyses were based on the 4,156 persons (17.1%) who endorsed lifetime suicidal ideation with or without a history of suicide attempt and who indicated whether and to whom they disclosed their ideation. Socio-demographics, current mental disorders, and social connectedness were assessed.

RESULTS

Half of those with suicidal ideation had not shared their ideation with anyone, 6.3% did so with health professionals only, 20% with friends or family only, and 20% with both healthcare professionals and close others. Male gender, older age, lower education level and poor social connectedness were associated with greater odds of non-disclosure. Adjusting for socio-demographics and social connectedness, suicidal behavior and mental disorders were overall associated an increased likelihood of sharing suicidal ideation with health professionals.

LIMITATIONS

Cross-sectional survey assessing lifetime suicidal ideation and disclosure.

CONCLUSIONS

The findings provide important insight into the individual and social factors to take into account in suicidal ideation disclosure.

[Suicide mortality in Colombia and México: Trends and impact between 2000 and 2013]

INTRODUCTION

Suicides are one of the main public health issues globally. Objective: To analyze the trends and impact of suicide mortality in Colombia and México between 2000 and 2013, nationally, by sex and age groups. Materials and methods: Mortality vital statistics from the Colombian Departamento Administrativo Nacional de Estadística and the Mexican Instituto Nacional de Estadística y Geografía were used. We conducted a descriptive and cross sectional study for which we calculated standardized mortality rates and years of life lost in people between 0 and 100 years of age. Results: In Colombia, the suicide mortality rate decreased between 2000 and 2013 for both sexes (28% for men and 38% for women); an opposite trend was observed in México (with an increase of 34% for males and 67% for females). In 2013, the years of life lost in Colombia were 0,32 among men and 0,15 among women, with a decreasing trend since 2000, whereas in México a level of 0,42 was observed in men and 0,2 in women, with an increasing trend since 2000. The age groups where suicides had a bigger impact were those of men 15 to 49 years of age in both countries, while suicides were more uniformly distributed among women between 15 and 84 years of age.

CONCLUSION

 Suicide mortality increased gradually in México, whereas in Colombia an opposite trend was observed. Suicides can be prevented, so it is fundamental to implement public health policies focused on timely identification, comprehensive prevention strategies and the study of associated risk factors.

The timing of general population and patient suicide in England, 1997-2012

BACKGROUND

There have been conflicting findings on temporal variation in suicide risk and few have examined the phenomenon in clinical populations. The study investigated seasonal and other temporal patterns using national data.

METHODS

Data on 73,591 general population and 19,318 patient suicide deaths in England between 1997 and 2012 were collected through the National Confidential Inquiry into Suicide examining suicide rates in relation to month of the year, day of the week, and individual days of national or religious significance.

RESULTS

Suicide incidence fell over successive months of the year and there was evidence of an overall spring peak. Monday was associated with the highest suicide rates and in the patient population this effect appeared to be more pronounced in those aged over 50 or those who lived alone. Suicide risk was significantly lower during Christmas, particularly for women. There was a peak in suicide on New Year's Day in the general population. Other 'special days' were not associated with a change in suicide incidence.

LIMITATIONS

We were limited to identifying associations between the variables investigated and were unable to explore causal mechanisms. We did not carry out comprehensive multi-variable adjustment in our regression models.

CONCLUSIONS

There is substantial seasonal and temporal variation in suicide deaths, and there appears to be some evidence in the clinical as well as the general population in England. Clinical services should be aware of the risk of suicide just after the weekend, especially in people who live alone, and the potential need for closer supervision during this period.

Suicidality in emergency medicine: Results from a retrospective analysis of emergency documentation forms

BACKGROUND

To analyze suicidal care episodes in emergency medical responses in Germany.

METHOD

Anonymized data from emergency care episodes in Ulm from 2004 to 2013 were analyzed retrospectively.

RESULTS

158 of 933 psychiatric emergencies (16 %) were suicide related, including 14 completed suicides, 25 care episodes with suicidal ideation, and 119 suicide attempts. Significantly more men than women completed suicide (χ²(2,N = 934) = 12.70, p = 0.02). 93 % of the total psychiatric emergencies received any medication at all, and only about 33 % were transported to a psychiatric hospital.

CONCLUSION

Psychiatric treatment for suicidality in emergency medicine requires improvement to ensure that patients receive adequate therapy.

Comportamientos de riesgo de suicidio y calidad de vida, por género, en adolescentes mexicanos, estudiantes de preparatoria

El estudio de los comportamientos que preceden al suicidio es importante no sólo por su asociación con éste sino por su impacto en la calidad de vida (CV). Dada la escasez de información sobre esta relación en adolescentes, el objetivo de este estudio fue analizar la asociación de los comportamientos de riesgo de suicidio y la CV, según género en adolescentes estudiantes de preparatoria mexicanos. Es un estudio transversal, en participantes de 14 a 18 años de edad. Se utilizó una versión traducida del Youth Risk Behavior Survey y la versión en español del Youth Quality of Life Instrument - Research version. Se aplicaron pruebas no paramétricas. Se pidió consentimiento informado a padres y estudiantes y se obtuvo aprobación de Comité de ética. Se consideró el modelo de desarrollo transaccional del comportamiento suicida de la juventud de Brigde et al. El análisis por separado para mujeres y hombres, mostró los comportamientos de riesgo de suicidio asociados con CV, y fue el comportamiento de haberse sentido triste o sin esperanza, el que presentó en general los tamaños de efecto mayores. Los modelos de regresión evidencian que algunos comportamientos de riesgo de suicidio aumentan la posibilidad de una CV inferior aún después de ajustar por covariables.

Which deliberate self-poisoning patients are most likely to make high-lethality suicide attempts?

BACKGROUND

The risk/rescue rating scale (RRRS) assesses the lethality of a suicide attempt, which is defined as the probability of inflicting irreversible damage. We assessed the lethality of suicide attempts using the RRRS and identified the socio-demographic profiles of patients who achieved high lethality in deliberate self-poisoning (DSP).

METHODS

A retrospective study was conducted to evaluate DSP patients who visited the emergency department of a tertiary teaching hospital between 2000 and 2011. The data included socio-demographic information, clinical variables, risk factors (e.g., the method used, whether consciousness was impaired, toxicity, reversibility and whether treatment was required) and rescue factors (e.g., location, who initiated the rescue, the probability of discovery, the accessibility of rescue, and delay until discovery). The high-risk group consisted of patients with 11-15 risk points, whereas patients in the low-rescue group had 5-11 risk points. We examined the characteristics of high-lethality suicide attempts (high-risk/low-rescue group).

RESULTS

A total of 1114 patients were enrolled in this study. Pearson's correlation analysis showed that the total risk score for patients with DSP was negatively associated with the total rescue score (r = -0.201, p < 0.001). Of the total number of DSP patients, 42 were included in the high-risk/low-rescue group. The multivariate logistic regression analyses showed significant associations between high-lethality suicide attempts and male gender (OR 2.70, 95 % CI 1.41-5.18, p = 0.003), older age (OR 1.02, 95 % CI 1.01-1.04, p = 0.015), and unemployment (OR 2.98, 95 % CI 1.41-6.33, p = 0.004).

CONCLUSION

This retrospective study demonstrates that male gender, advanced age, and unemployed status were associated with high-lethality suicide attempts in DSP patients.

Suicide in women

Suicide is a global public health problem. Asia accounts for 60% of the world's suicides, so at least 60 million people are affected by suicide or attempted suicide in Asia each year. The burden of female suicidal behavior, in terms of total burden of morbidity and mortality combined, is more in women than in men. Women's greater vulnerability to suicidal behavior is likely to be due to gender related vulnerability to psychopathology and to psychosocial stressors. Suicide prevention programmes should incorporate woman specific strategies. More research on suicidal behavior in women particularly in developing countries is needed.

Ethnic and Gender Differences in Additive Effects of Socio-economics, Psychiatric Disorders, and Subjective Religiosity on Suicidal Ideation among Blacks

BACKGROUND

This study aimed to investigate the additive effects of socio-economic factors, number of psychiatric disorders, and religiosity on suicidal ideation among Blacks, based on the intersection of ethnicity and gender.

METHODS

With a cross-sectional design, data came from the National Survey of American Life, 2001-2003, which included 3570 African-American and 1621 Caribbean Black adults. Socio-demographics, perceived religiosity, number of lifetime psychiatric disorders and lifetime suicidal ideation were measured. Logistic regressions were fitted specific to groups based on the intersection of gender and ethnicity, while socioeconomics, number of life time psychiatric disorders, and subjective religiosity were independent variables, and lifetime serious suicidal ideation was the dependent variable.

RESULTS

Irrespective of ethnicity and gender, number of lifetime psychiatric disorders was a risk factor for lifetime suicidal ideation (odds ratio [OR] ranging from 2.4 for Caribbean Black women to 6.0 for Caribbean Black men). Only among African-American men (OR = 0.8, 95% confidence interval = 0.7-0.9), perceived religiosity had a residual protective effect against suicidal ideation above and beyond number of lifetime psychiatric disorders. The direction of the effect of education on suicidal ideating also varied based on the group.

CONCLUSIONS

Residual protective effect of subjective religiosity in the presence of psychiatric disorders on suicidal ideation among Blacks depends on ethnicity and gender. African-American men with multiple psychiatric disorders and low religiosity are at very high risk for suicidal ideation.

A Comparison of Suicides and Undetermined Deaths by Poisoning among Women: An Analysis of the National Violent Death Reporting System

The study compared the prevalence of common suicide risk factors between poisoning deaths classified as injuries of undetermined intent or suicides among women. Data were derived from the 2003-10 National Violent Death Reporting System. Multiple logistic regression assessed the factors associated with 799 undetermined deaths (relative to 3,233 suicides). Female decedents with lower education, a substance use problem, and a health problem were more likely to be classified as undetermined death. Older women, those with an intimate partner problem, financial problem, depressed mood, mental health problem, attempted suicide, and disclosed intent to die were less likely to be classified as undetermined death. The present study raises the possibility that many (perhaps most) undetermined female poisoning deaths are suicides.

Exploring Prospective Predictors of Completed Suicides

Background: This study was based on over 30,000 respondents who completed General Social Surveys between 1978 and 2002. Aims: We approached these respondents prospectively, comparing and contrasting the responses of those who subsequently died by suicide (N = 141) with those who died from all other causes (N = 9,115). Method: We employed chi-square and logistic regression analyses of important demographic confounders to test for statistically significant differences between suicide decedents and all other decedents. Results: Suicide decedents died on average 2 years sooner than all other decedents. When covariates of age and gender were applied, suicide decedents exhibited greater acceptance of suicide for dealing with various adverse life circumstances, were more likely to have been the gun owners in their households, lived in regions where gun ownership was more commonplace, and held less strong religious beliefs and less of a belief of an afterlife. Conclusion: The observed affinity between attitudes of suicide acceptability and completed suicide suggests a potential for creating a meaningful assessment tool to identify those positioned at the extreme end of the suicide risk continuum.

Estudo compreensivo sobre suicídio de mulheres idosas de sete cidades brasileiras

Parte-se de uma pesquisa multicêntrica realizada no Brasil, em que se analisam 51 casos de suicídio de idosos (de 40 homens e 11 mulheres) mediante autópsias psicossociais. Aprofunda-se o estudo dos 11 casos relativos às mulheres. A interpretação dos dados empíricos se fundamenta em autores clássicos e em recente literatura nacional e internacional sobre o fenômeno. Motivos que levam as mulheres ao suicídio são, em parte, diferentes dos homens. Como eles, as mulheres morrem preferencialmente por enforcamento e frequentemente seu suicídio associa-se a doenças degenerativas e comorbidades. As diferenças principais se devem a questões culturais de gênero. Os resultados convergem em grande parte com a literatura e revelam que, no Brasil, os fatores principais associados ao suicídio feminino são: violência de gênero e intrafamiliar, sofrimento por perdas de pessoas referenciais e da função tradicional como esposa e mãe, e depressão. Recomenda-se maior atenção ao efeito cumulativo de agravos no envelhecimento das mulheres, sobretudo os vinculados às especificidades de gênero.

The art of dying as an art of living: historical contemplations on the paradoxes of suicide and the possibilities of reflexive suicide prevention

The main aim of this paper is to reconstruct different aspects of the history of ideas of suicide, from antiquity to late modernity, and contemplate their dialectical tension. Reflexive suicide prevention, drawing on the ancient wisdom that the art of living is inseparable from the art of dying, takes advantage, it is argued, of the contradictory nature of suicide, and hence embraces, rather than trying to overcome, death, pain, grief, fear, hopelessness and milder depressions. This approach might facilitate the transformation of inner shame to inter-personal guilt, which is the precondition for coping with losses through grieving that is shared with others. The traditional projection of suicide on the 'Other', reinforced by modernity's bio-political suppression of death, has inhibited development of good suicide prevention. Awareness of the ambiguity and ambivalence found in suicide may work as a resource when measures are taken to address as many causal mechanisms as possible, and bringing special emphasis to external factors.
