THE ASSOCIATION BETWEEN ALCOHOL MISUSE AND SUICIDAL BEHAVIOUR

Patterns and predictors of alcohol misuse trajectories from adolescence through early midlife

We took a multilevel developmental contextual approach and characterized trajectories of alcohol misuse from adolescence through early midlife, examined genetic and environmental contributions to individual differences in those trajectories, and identified adolescent and young adult factors associated with change in alcohol misuse. Data were from two longitudinal population-based studies. FinnTwin16 is a study of Finnish twins assessed at 16, 17, 18, 25, and 35 years (N = 5659; 52% female; 32% monozygotic). The National Longitudinal Study of Adolescent to Adult Health (Add Health) is a study of adolescents from the United States, who were assessed at five time points from 1994 to 2018 (N = 18026; 50% female; 64% White, 21% Black, 4% Native American, 7% Asian, 9% Other race/ethnicity). Alcohol misuse was measured as frequency of intoxication in FinnTwin16 and frequency of binge drinking in Add Health. In both samples, trajectories of alcohol misuse were best described by a quadratic growth curve: Alcohol misuse increased across adolescence, peaked in young adulthood, and declined into early midlife. Individual differences in these trajectories were primarily explained by environmental factors. Several adolescent and young adult correlates were related to the course of alcohol misuse, including other substance use, physical and mental health, and parenthood.

Alcohol use, self-harm and suicide: a scoping review of its portrayal in the Sri Lankan literature

Background

Suicide is a global public health problem. Compared to other middle-income countries, much literature has been generated on the topic of self-harm and suicide in Sri Lanka. Harmful use of alcohol is a well-known risk factor to self-harm and suicide, however the connection needed further exploration.

Aim

The aim was to investigate alcohol's role in self-harm and suicide in Sri Lanka to inform policy and prevention programs and future research priorities.

Methods

We performed a scoping review exploring how the association between alcohol use, self-harm and suicide in Sri Lanka is presented in scientific literature from August 1, 2008 to December 31, 2022. Thematic analysis was used to explore emerging themes.

Results

Altogether 116 peer-reviewed articles were included. Three themes emerged: (i) gendered, inter-relational explanations of alcohol's role in self-harm, (ii) hospital management of patients who co-ingested alcohol and pesticides, and (iii) proposed research and interventions targeting alcohol, self-harm and suicide. The articles' recommendations for policy, prevention and research priorities included: Family- and community-based alcohol, self-harm and suicide reduction interventions; viewing self-harm as a window of opportunity for health personnel to intervene in families affected by harmful alcohol consumption; and introduction of and increased access to treatment of alcohol use disorder at the individual level.

Conclusion

Suggestions for alcohol, self-harm, and suicide prevention interventions were primarily targeted at the community, though this might also reflect the limited treatment, mental health, and alcohol support available in the country. Future research should explore and test context-appropriate interventions integrating alcohol and self-harm prevention and treatment.

Exploring psychological and psychosocial correlates of non-suicidal self-injury and suicide in college students using network analysis

BACKGROUND

Non-suicidal self-injury (NSSI) and suicide are a serious health concern in young people. Remarkable progress has been made in understanding the correlates and risk factors for suicidality. However, it remains unclear the complex interplay between different factors and which factors are most saliently associated with NSSI and suicide risk and should be targeted for interventions.

METHODS

This study utilized network analysis to examine the interrelationship between NSSI, suicide and a variety of psychological (e.g., depression, psychotic-like experiences) and psychosocial (e.g., childhood maltreatment, family dysfunction, being bullied and social support) correlates in a sample of Chinese first year college students (n = 2328).

RESULTS

The severity of depressive symptoms was the only factor connected to both NSSI and suicide. Other psychiatric factors like psychotic experiences could only act in an indirect way via the bridging effect of depression. Emotional abuse, compared with other forms of childhood adversities, was found to be the most influential maltreatment form associated with suicidal ideation and attempts. Finally, social support showed the potential to lower the risk of self-injury and suicide in young people.

LIMITATIONS

Only a subset of risk and resilience factors of NSSI and suicide were included. Causal inference was impossible due to the cross-sectional design.

CONCLUSIONS

Our findings highlighted the importance of identifying risk groups with mental illnesses or negative childhood events, and providing additional support during the key time of transitioning into higher education.

Alcohol use during pregnancy: findings from a gender-based violence survey in Mongolia

This study aimed to explore the risk factors for alcohol use during pregnancy in Mongolia, wherein high-risk alcohol use is prevalent. We analyzed nationwide data from the Gender-Based Violence (GBV) Survey of Mongolia conducted in 2017. We conducted an analysis restricted to 2714 women who had given birth within 5 years of the survey and who had responded to questions about their health-related behaviors during pregnancy. We assessed the association between alcohol use during pregnancy and pregnancy-related factors, including maternal age, educational attainment, history of abortion, smoking during pregnancy, unintended pregnancy, prior experience of sexual and physical violence, physical violence during pregnancy, and current binge drinking while also considering their residential region. Alcohol use during pregnancy was reported in 5.4% of the participating women. Unintended pregnancy for women (OR = 1.95, 95% confidence interval [CI]: 1.60, 2.38), abortion history (1.89, 95% CI: 1.60, 2.24), smoking during pregnancy (8.30, 95% CI: 6.60, 10.43), physical violence during pregnancy (2.22, 95% CI: 1.75, 2.81), and being a binge drinker (6.05, 95% CI: 3.63, 10.10) were associated with higher odds of alcohol use during pregnancy. Associations with maternal age, marital status, higher education, or multiparity were not evident. Our finding provides knowledge of risk factors for alcohol drinking among pregnant women and evidence for another harm of gender-based violence. This would contribute to the development of effective strategies for preventing antenatal exposure to alcohol in Mongolia.

Development of a Checklist for Predicting Suicidality Based on Risk and Protective Factors: The Gwangju Checklist for Evaluation of Suicidality

OBJECTIVE

The aim of the study was to develop a checklist for mental health clinicians to predict and manage suicidality.

METHODS

A literature review of the risk and protective factors for suicide was conducted to develop a checklist for evaluating suicidality.

RESULTS

The fixed risk factors included sex (male), age (older individuals), history of childhood adversity, and a family history of suicide. Changeable risk factors included marital status (single), economic status (poverty), physical illness, history of psychiatric hospitalization, and history of suicide attempts. Recent discharge from a mental hospital and a recent history of suicide attempts were also included. Manageable risk factors included depression (history and current), alcohol problems (frequent drinking and alcohol abuse), hopelessness, agitation, impulsivity, impaired reality testing, and command hallucinations. Protective factors included responsibility to family, social support, moral objections to suicide, religiosity, motivation to get treatment, ability to cope with stress, and a healthy lifestyle. A final score was assigned based on the sum of the risk and protective factor scores.

CONCLUSION

We believe that the development of this checklist will help mental health clinicians to better assess those at risk for suicidal behavior. Further studies are necessary to validate the checklist.

Understanding the relationship between social determinants of health and maternal mortality: Scientific Impact Paper No. 67

Within this document we use the terms pregnant woman and women's health. However, it is important to acknowledge that it is not only people who identify as women for whom it is necessary to access care. Obstetric and gynaecology services and delivery of care must therefore be appropriate, inclusive and sensitive to the needs of those individuals whose gender identity does not align with the sex they were assigned at birth.

Associations between Mental Resilience, Mood, Coping, Personality, and Hangover Severity

Extensive research exists on relationships between psychological constructs and alcohol consumption. However, research on relationships with hangover severity remains limited. This study aimed to assess the associations between mental resilience, mood (i.e., depression, anxiety, and stress), coping, personality, and hangover severity. A total of N = 690 participants completed an online survey by answering questions regarding their demographics, alcohol use, hangover prevalence and severity, and several psychological assessments (Brief Resilience Scale, DASS-21, Brief Cope, and Brief Version of the Big Five Personality Inventory). Significant associations were found between hangover severity and mental resilience, mood, and avoidant coping. Higher levels of mental resilience were associated with less severe hangovers, whereas poorer mood was associated with more severe hangovers. No significant associations were found with personality traits. These findings demonstrate that several associations between psychological constructs and hangover severity exist and suggest a role of psychological factors in the pathology of the alcohol hangover. As our findings contrast with the results of previous studies that did not report an association between mental resilience and the presence and severity of hangovers, further research is warranted.

Alcohol in long-term care homes: A qualitative investigation with residents, relatives, care workers and managers

Introduction

Western societies are aging rapidly, and habitual use of alcohol is changing among older adults. Hence, care facilities are facing novel challenges regarding alcohol use. This pioneering qualitative study seeks to investigate the role of alcohol in care homes, as seen from the perspectives of residents, care workers, relatives, and institution management simultaneously.

Method

Five residents, four care workers, three relatives, and two care home managers participated in semi-structured interviews lasting 60 minutes maximum. An interpretative phenomenological analysis framework were utilised for the analysis.

Results

It seems that there is a positive attitude towards the use of alcohol in care homes across the four groups of participants. They find that the use of alcohol is presently low among the residents. Importantly there appears to be an important symbolic value in the rituals surrounding alcohol which is upheld by all four groups.

Conclusion

While experiences between the four groups seem to converge regarding the use of alcohol, there are still some important differences. Importantly, we suggest that these unique views be utilised in developing methods for handling alcohol use in care homes in the future.

Epidemiology of DSM-5 alcohol use disorder in U.S. military veterans: Results from the National Health and Resilience in Veterans Study

BACKGROUND

Alcohol use disorder (AUD) is a prevalent public health concern in the U.S. that disproportionately affects veterans relative to civilians. Given changes to the demographic composition of the veteran population and AUD diagnostic criteria in the DSM-5, updated knowledge regarding the epidemiology of DSM-5 AUD in a national sample of veterans is critical to informing the population-based burden of this disorder.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4069 U.S. veterans. Lifetime DSM-5 AUD (mild, moderate, severe) and past-year DSM-5 AUD were assessed using validated self-report measures, and sociodemographic, military, and psychiatric characteristics associated with lifetime and past-year AUD were evaluated.

RESULTS

Prevalences of lifetime and past-year DSM-5 AUD were 40.8% (95% confidence interval [CI]=39.2-42.3%) and 10.5% (95%CI=9.6-11.5%), respectively. Lifetime prevalences of mild, moderate, and severe AUD were 20.5%, 8.3%, and 12.0%, respectively. Veterans with lifetime AUD had elevated rates of psychiatric disorders and suicidal behavior, which generally increased as a function of AUD severity. Lifetime AUD was also associated with being younger, male, white, unmarried, retired and experiencing more adverse childhood experiences and traumas. For past-year AUD, being younger, male, white, having more adverse childhood experiences, and experiencing lifetime PTSD were significant correlates.

CONCLUSIONS

AUD is highly prevalent among U.S. veterans and associated with substantial psychopathology, including elevated odds of suicidal behaviors. Results underscore the importance of comprehensive screening and preventive efforts for AUD, and interventions that concurrently target overlapping alcohol use and psychiatric difficulties.

Comorbid alcohol-related problems and suicidality disproportionately impact men and emerging adults among individuals with depressive symptoms

OBJECTIVE

Depressive disorders are common among adults with alcohol use disorder and with suicidality; however, demographic differences in comorbid alcohol use disorder, binge drinking, and suicidality are understudied. The objective of this study was to determine the extent to which comorbid suicidality and alcohol use disorders and comorbid suicidality and binge drinking differ by age and gender among adults with depressive symptoms.

METHOD

The sample included adults (unweighted N=29,460) in the United States who completed the 2015-2018 National Survey of Drug Use and Heath and screened positively for depression. Gender and age groups odds of alcohol use disorder only, suicidality only, and alcohol use disorder+suicidality were compared to neither problem. Similar analyses were conducted for binge drinking.

RESULTS

Men showed disproportional odds of alcohol use disorder only, all suicidality and alcohol use disorder comorbidities, and binge drinking+active suicidal ideation than women. Emerging adults showed higher odds of: passive and active suicidal ideation only and suicidality+alcohol use disorder than adults 35 and older; binge drinking only, binge drinking+passive suicidal ideation, and binge drinking+active suicidal ideation than all older adults; binge drinking+suicide planning and binge drinking+attempts than adults 50 and older.

LIMITATIONS

Because participants all reported depression symptoms either at the subclinical or clinical level, demographic differences in suicidality, alcohol use disorder, and binge drinking found in this study cannot be generalized to non-depressed samples.

CONCLUSIONS

Treatment providers should be aware of disproportionately higher odds of comorbid suicidality and alcohol use disorder, and suicidality and binge drinking among men and emerging adults.

Prevalence and correlates of suicidal behavior among a national population-based sample of adults in Kiribati

INTRODUCTION

Suicidal behavior is an underresearched cause of death in the Western Pacific region. The study aimed to investigate the prevalence and associated factors of suicidal behavior in a population-based survey among 18-69 year-old persons in Kiribati.

METHOD

Cross-sectional nationally representative data of 2156 18-69 year old persons (37 years were the median age) from the "2015-16 Kiribati STEPS survey" were analyzed.

RESULTS

The results indicate that 5.1% of participants had ever attempted suicide and 9.5% engaged in past 12-month suicidal behavior (ideation, planning, and/or attempts). In adjusted logistic regression analysis, cohabiting, psychological distress, and having had a heart attack, angina, or stroke were associated with lifetime suicide attempts. Female sex, younger age, lower education, psychological distress, heart attack, angina or stroke, and high physical activity were positively associated with past 12-month suicidal behavior. In addition, in unadjusted analysis, alcohol family problems, alcohol dependence, family members attempted suicide, and sedentary behavior (3 to <6 hours/day) were associated with lifetime suicide attempts and/or past 12-month suicidal behavior.

CONCLUSION

Almost one in 10 participants were engaged in suicidal behavior in the past 12 months and several factors were detected which could be targeted in intervention activities.

Impulsivity Scale-12 and its utilization in alcohol use disorder

INTRODUCTION

One of the core symptoms of alcohol use disorder (AUD) is impulsivity. The recently published study on the Impulsivity Scale 12 (IS-12) offers a promising tool to use in clinics working with clients with AUD due to its simplicity. IS-12 includes subscales related tocognitive impulsivity and behavioral impulsivity, which are related to different aspects of AUD symptomatology. The aim of the study was to adapt IS-12 to polish and test its utility in a sample of patients diagnosed with AUD.

METHODS

Using a Confirmatory Factor Analysis, we compared the two-factor model of the Polish adaptation of the BIS-11 and the IS-12 on a sample of 615 patients diagnosed with AUD. Additionally, we explored the association between the IS-12's cognitive impulsivity and behavioral impulsivity subscales and depressive symptoms, AUD severity, and suicidal ideation using Structural Equation Modeling on a subsample of 450 patients with AUD.

RESULTS

The IS-12 demonstrated a better model fit and good reliability compared to the BIS-11. Moreover, cognitive impulsivity predicted suicidal ideation, but not AUD severity, while behavioral impulsivity predicted AUD severity, but not suicidal ideation. Both subscales of IS-12 predicted depressive symptoms.

CONCLUSION

Consistent with prior work, findings indicate that the second-order factor model of the BIS-11 had reliability issues and evidenced poor model fit. In contrast, the IS-12 demonstrated a satisfactory model fit and was predictive of clinical symptomatology. Thus, utilizing an easy tool, such as IS-12, might be beneficial for researchers and clinicians working with patients with AUD.

A comparative analysis of the substance use and mental health characteristics of nurses who complete suicide

AIMS AND OBJECTIVES

To describe the substance use and mental health characteristics of nurses who complete suicide compared to non-nurses.

BACKGROUND

Nurses are at higher risk of suicide than the general population. The relationship between substance use, mental health and suicide in a large sample of nurses in the USA has not been previously described.

DESIGN

Retrospective observational quantitative analysis.

METHODS

Suicide data were retrospectively analysed in the Centers for Disease Control and Prevention National Violent Death Reporting System from 2003 to 2017. Data were compared between nurses who died by suicide (n = 2,306) and non-nurses who died by suicide (n = 185,620) using odds ratios calculations and chi-square test of proportions to detect independent risk factors of suicide completion in nurses. This study followed the STROBE guidelines.

RESULTS

Significant differences between nurses and non-nurses were found. Among decedents for whom substances were implicated as a cause of death, nurses were far more likely to be positive at the time of death for almost all substance classifications. Both male and female nurses were more likely than non-nurses to have a mental health problem reported. Among both female and male nurses, job problems were more prevalent compared to non-nurses (12.8% and 19.9% versus 7.2% and 11.9%, respectively). Female nurses were more likely to have a physical health problem compared to female non-nurses, male nurses and male non-nurses (26.2% versus 21.3%, 22% and 20.4%).

CONCLUSION

Unique relationships between substance use and mental health exist among nurses who complete suicide which may offer specific opportunities for interventions to reduce suicide.

RELEVANCE TO CLINICAL PRACTICE

Efforts to address workplace stress, facilitate self-referral for risky substance use, encourage mental health treatment and reduce the stigma associated with seeking help all offer potential interventions to reduce nurse suicide.

Suicide Risk and Addiction: The Impact of Alcohol and Opioid Use Disorders

Purpose of Review

Suicide is a major public health concern and a leading cause of death in the US. Alcohol and opioid use disorders (AUD/OUD) significantly increase risk for suicidal ideation, attempts, and death, and are the two most frequently implicated substances in suicide risk. We provide a brief overview of shared risk factors and pathways in the pathogenesis of AUD/OUD and suicidal thoughts and behaviors. We also review clinical recommendations on inpatient care, pharmacotherapy, and psychotherapeutic interventions for people with AUD/OUD and co-occurring suicidal ideation and behavior.

Recent Findings

Among people with an underlying vulnerability to risk-taking and impulsive behaviors, chronic alcohol intoxication can increase maladaptive coping behaviors and hinder self-regulation, thereby increasing the risk of suicide. Additionally, chronic opioid use can result in neurobiological changes that lead to increases in negative affective states, jointly contributing to suicide risk and continued opioid use. Despite significantly elevated suicide risk in individuals with AUD/OUD, there is a dearth of research on pharmacological and psychosocial interventions for co-occurring AUD/OUD and suicidal ideation and behavior.

Summary

Further research is needed to understand the effects of alcohol and opioid use on suicide risk, as well as address notable gaps in the literature on psychosocial and pharmacological interventions to lower risk for suicide among individuals with AUD/OUD.

Comparative associations of problematic alcohol and cannabis use with suicidal behavior in U.S. military veterans: A population-based study

Alcohol use disorder (AUD) and cannabis use disorder (CUD) are each associated with increased suicidal behavior, but it is unclear how their comorbidity relates to suicide risk. Understanding these associations in U.S. military veterans is especially important, given their heightened risk for suicide, high prevalence of AUD, and increasing access to cannabis. We compared associations of probable AUD, CUD, and AUD/CUD with suicide ideation, plan(s), and attempt(s) in a nationally representative sample of 4,069 veterans surveyed in 2019-2020 as part of the National Health and Resilience in Veterans Study. Among veterans who screened positive for current AUD, 8.7% also screened positive for current CUD. Among veterans who screened positive for current CUD, 33.3% screened positive for current AUD. Current and lifetime positive screens for AUD, CUD, and AUD/CUD were each strongly and independently associated with past-year suicide ideation and lifetime suicide ideation, plan(s), and attempt(s) [odds ratios (ORs) = 1.6-8.7]. Relative to veterans who screened positive for AUD only, veterans who screened positive for AUD/CUD and CUD only had higher odds of past-year suicide ideation (AUD/CUD: OR = 3.3; CUD only: OR = 2.4), lifetime suicide ideation (AUD/CUD: OR = 1.9; CUD only: OR = 2.6) and lifetime suicide plan(s) (AUD/CUD: OR = 1.7; CUD only: OR = 6.1). Collectively, findings suggest that screening positive for CUD might be an especially strong indicator of suicide ideation and planning in veterans with and without AUD, independent of sociodemographic, military, trauma, and other psychiatric factors. These findings underscore the importance of routine screening for CUD in suicide prevention efforts, especially as cannabis becomes more widely available.

Prevalence and correlates of suicidal behaviour among a national population-based sample of adults in Zambia

Background

Suicide is a major public health issue.

Aim

This study aimed to assess the prevalence and correlates of lifetime suicide attempts and past 12-month suicidal behaviour (ideation, plans and/or attempts) among adults (18–69 years).

Setting

Zambia.

Method

National cross-sectional data from 4302 adults (median age: 31 years) who took part in the ‘2017 Zambia STEPS survey’ were analysed.

Results

The results indicate that 2.3% of participants had ever attempted suicide and 8.5% engaged in past 12-month suicidal behaviour (ideation 7.8%, plan 3.6% and/or attempt 1.1%). In adjusted logistic regression analysis, having a family member who died from suicide, having had a heart attack, angina or stroke and daily tobacco smoking were associated with ever suicide attempt. In adjusted logistic regression, female sex, non-paid work status (including student, homeworker and retired), alcohol use-related family problem, passive smoking, heart attack, angina or stroke and alcohol dependence were positively associated with past 12-month suicidal behaviour, and belonging to other ethnic groups was negatively associated with past 12-month suicidal behaviour. In addition, in an unadjusted analysis, 18–24-year-old participants, those who were never married, separated, divorced or widowed, having urban residence, family members died from suicide, having lower systolic blood pressure and daily smokeless tobacco use, were associated with past 12-month suicidal behaviour.

Conclusion

Almost 1 in 10 participants was engaged in suicidal behaviour in the past 12 months, and several associated indicators were found that can assist in planning interventions.

Prediction of Suicide-Related Events by Analyzing Electronic Medical Records from PTSD Patients with Bipolar Disorder

Around 800,000 people worldwide die from suicide every year and it’s the 10th leading cause of death in the US. It is of great value to build a mathematic model that can accurately predict suicide especially in high-risk populations. Several different ML-based models were trained and evaluated using features obtained from electronic medical records (EMRs). The contribution of each feature was calculated to determine how it impacted the model predictions. The best-performing model was selected for analysis and decomposition. Random forest showed the best performance with true positive rates (TPR) and positive predictive values (PPV) of greater than 80%. The use of Sertraline, Fentanyl, Aripiprazole, Lamotrigine, and Tramadol were strong indicators for no SREs within one year. The use of Haloperidol, Trazodone and Citalopram, a diagnosis of autistic disorder, schizophrenic disorder, or substance use disorder at the time of a diagnosis of both PTSD and bipolar disorder, predicted the onset of SREs within one year. Additional features with potential protective or hazardous effects for SREs were identified by the model. We constructed an ML-based model that was successful in identifying patients in a subpopulation at high-risk for SREs within a year of diagnosis of both PTSD and bipolar disorder. The model also provides feature decompositions to guide mechanism studies. The validation of this model with additional EMR datasets will be of great value in resource allocation and clinical decision making.

Suicidal behavior among people with epilepsy in Northwest Ethiopia: A comparative cross-sectional study

INTRODUCTION

Premature mortality is common in people with epilepsy, but the causes vary where suicide is considered as one of the commonest.

OBJECTIVE

The objective of this study was to compare suicidal behavior between people with epilepsy and the general population and identify associated factors in Northwest Ethiopia.

METHODS

We have conducted a comparative cross-sectional study in Northwest Ethiopia. We have selected people with epilepsy from outpatient departments and the comparisons from the general population. Suicidal behavior was assessed by the revised version of Suicidal Behaviors Questionnaire (SBQ-R). Logistic regression was implemented to look for associations between factors and the dependent variable.

RESULTS

The prevalence of suicidal behavior in people with epilepsy was 18.2%, significantly higher than the community sample, which was 9.8% (p-value = .001). This difference persists in the multivariable logistic regression model by which the odds of suicidal behavior in people with epilepsy was two times more as compared to the community sample. Other variables positively associated with suicidal behavior for the overall sample were depressive symptoms, no formal education, divorced/widowed marital status, and higher perceived criticism. Better social support was protective factor for suicidal behavior.

CONCLUSION

The proportion of suicidal behavior is twofold higher in people with epilepsy than the general population. Routine screening for suicide risk should be an integral part of epilepsy treatment.

Coronavirus disease 2019 crisis and intentional injuries: now is not the time to erode alcohol control policies

In Canada, and elsewhere, the coronavirus disease 2019 (COVID-19) crisis has resulted in a social, economic, and alcohol policy environment that is likely to contribute to a rise in intentional injuries, whether interpersonal or self-directed violence. Heavy drinking has been identified as an important risk factor for intentional injuries, and with the erosion of alcohol control policies on alcohol availability, heavy drinking is likely to increase. During a time of social isolation, economic loss, psychological distress, and reduced access to health services and support networks, all of which are catalytic factors for both intentional injuries and heavy alcohol use, what is needed is individualized and population-based preventive interventions aimed at reducing alcohol consumption, rather than decisions to increase certain forms of alcohol availability.

A drink before suicide: analysis of the Queensland Suicide Register in Australia

AIMS

Previous studies analysing blood alcohol concentration (BAC) at the time of suicide have primarily focused on sociodemographic factors. Limited research has focused on psychosocial factors and co-ingestion of other substances to understand the mechanisms of how alcohol contributes to death by suicide. The aim was to examine time trends, psychosocial factors related to acute alcohol use and co-ingestion of alcohol and other substances before suicide.

METHODS

The Queensland Suicide Register in 2004-2015 was utilised and analysed in 2019. The cut-off point for positive BAC was set at ⩾0.05 g/dl. Substances were categorised as medicines, illegal drugs and other. Medicines were coded by the Anatomical Therapeutic Chemical (ATC) classification system. Joinpoint regression, univariate odds ratios, age and sex-adjusted odds ratios and Forward Stepwise logistic regression were performed.

RESULTS

BAC information was available for 6744 suicides, 92% of all cases in 2004-2015. The final model showed that independent factors distinguishing BAC+ from BAC- were: age group 25-44 years, Australian Indigenous background, being separated or divorced, hanging, diagnosis of substance use, lifetime suicidal ideation, relationship and interpersonal conflict, not having psychotic and other psychiatric disorder, and no nervous system drugs or any other substances in blood at the time of suicide.

CONCLUSIONS

Our findings suggest that people who die by suicide while under the influence of alcohol are more likely to be under acute stress (e.g. separation) and not have earlier psychiatric conditions, except substance use. This highlights the importance of more strict alcohol policies, but also the need to improve substance use treatment.

Alcohol Consumption and Violent Deaths in the City of Sao Paulo in 2015

Background: Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control, making people more vulnerable to violence and accidents, with thus a potential association between alcohol consumption and violent deaths. Objective: To assess the association between alcohol consumption and violent deaths in the city of Sao Paulo, Brazil, in 2015, and its relationship with gender, age, cause of death and blood alcohol concentration (BAC) of victims. Methods: A cross-sectional retrospective study was conducted by collection of data from 2,882 victims of violent deaths subjected to examination of BAC from the archives of the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Results: Alcohol was detected in blood samples of 27.06% of the victims and mean BAC levels were 1.92 ± 1.24 g/L. The mean age of the victims was 33.49 ± 15.19 years. The majority of the victims were male (84.14%) and the prevalence of positive BAC was higher amongst men (28.74%) than women (18.16%). Homicide was the most prevalent cause of death in the sample (36.57%), but there were a higher proportion of traffic accidents victims with positive BAC (32.01%), as well as higher BAC levels in these victims (46.77% in the range of 1.6-2.5 g/L). Conclusions: The results obtained in this study support a potential association between alcohol consumption and violent deaths in the city of Sao Paulo, mainly in traffic accidents victims.

Depressive symptoms, suicidal ideation, and mental health care-seeking in central Mozambique

PURPOSE

There is scant research on depressive symptoms (DS), suicidal ideation (SI), and mental health care-seeking in Mozambique.

METHODS

Generalized estimating equations were used to assess factors associated with DS, SI, and mental health care-seeking among 3080 individuals interviewed in a representative household survey in Sofala and Manica provinces, Mozambique.

RESULTS

19% (CI 17-21%) of respondents reported DS in the past year and 17% (CI 15-18%) lifetime SI. Overall, only 10% (CI 8-11%) of respondents ever sought any care for mental illness, though 26% (CI 23-29%) of those reporting DS and/or SI sought care. 90% of those who sought care for DS received treatment; however, only 46% of those who sought care for SI received treatment. Factors associated with DS and SI include: female gender, divorced/separated, widowed, and > 55 years old. Respondents in the bottom wealth quintile reported lower DS, while those in upper wealth quintiles reported higher prevalence of SI. Individuals with DS or SI had significantly elevated measures of disability-especially in doing household chores, work/school activities, standing for long periods, and walking long distances. Factors associated with care-seeking include: female gender, rural residence, divorced/separated, and > 45 years old. Individuals in lower wealth quintiles and with no religious affiliation had lower odds of seeking care.

CONCLUSIONS

DS and SI are prevalent in central Mozambique and treatment gaps are high (68% and 89%, respectively). An urgent need exists for demand- and supply-side interventions to optimize the delivery of comprehensive community-based mental healthcare in Mozambique.

The role of depression in unnatural death: A case-based retrospective study

BACKGROUND

Depression affects the life of millions around the globe and perhaps also the manner of death. This study examined the role of depression in specific causes of unnatural death and whether alcohol and substance use affect this relationship, in one locality in Scotland.

METHODS

The research used a retrospective case-based study approach to analyse 168 cases, quantifying data reported in mortuary files to allow for quantitative statistical analysis of associations and differences amongst the variables.

RESULTS

A diagnosis of depression was associated with a higher likelihood of unnatural death due to suicide, drugs or homicide. A diagnosis of substance abuse was associated with a diagnosis of depression and with an increased likelihood of death due to suicide or drugs. A diagnosis of alcohol abuse was associated with a reduced likelihood of a diagnosis of depression but was associated with an increased likelihood of suicide.

LIMITATIONS

This study relied on a small sample from one locality in Scotland which limited the ability to generalise the results and the retrospective case-based design also limited the potential for checking data accuracy or to consider temporal relationships, which limited the ability to interpret causality.

CONCLUSIONS

This study found that there was a relationship between depression and unnatural death, which was mediated by alcohol and substance use. The importance of this study lies within the recognition of these relationships which identified the complexities of these relationships but suggested that some unnatural deaths within this population could be prevented.

Liability and Patient Suicide

Suicide is one of the leading causes of liability against a psychiatrist treating adult patients. Reducing the risk of liability entails understanding the phenomenology of suicide, approaching suicide risk assessment from a clinical perspective, conceptualizing how malpractice cases unfold, examining the issues of foreseeability and proper risk assessment, and developing a risk management approach to mitigate against the potential for a bad outcome. The use of various suicide screening risk assessments in certain clinical contexts is a potentially useful first step in identifying the need for further risk assessment. In conducting a more detailed review of a patient's risk, nonsuicidal self-injury is typically distinguished from suicidal intent and action, although morbidity and mortality can also be associated with any deliberate self-injury. Understanding the concepts of means reduction and risk management planning are essential elements to assist in helping reduce risk. Special attention to risk reduction related to firearms has received increased attention in recent years. Proper assessment, and documentation thereof in clinical records can assist in reducing liability. This article reviews these basic elements for the general practitioner of adult psychiatry related to suicide risk, assessment, and liability surrounding patient suicide.

[Predictors of suicidal behaviour in adolescents with depressive disorders]

A review of recent publications is devoted to risk factors for suicidal behavior in adolescents with depressive disorders. The authors summarized Russian and international studies on the clinical course of affective disorders, in particular bipolar disorders, their clinical heterogeneity and incompleteness in adolescence. Particular attention is given to the complexity of early identification of predictors of suicidal behavior in depressive disorders due to comprehensiveness of exogenous and endogenous effects characteristic of adolescence. The role of genetic loading for affective disorders, problems of children having parents with affective disorders, social and psychological factors (violence in families, school bullying etc.) and risks of suicidal behavior are described. It is of great significance to investigate premorbid adjustment, subaffective manifestations of disorders in adolescence to predict the trajectory of the disease, its complications in the form of suicidal behavior and opportunities for early intervention.

Predicting Suicide Ideation in the Military: The Independent Role of Aggression

The purpose of this study was to examine the longitudinal relationship between aggression and suicide ideation when controlling for other externalizing (i.e., alcohol misuse and risk-taking) and internalizing (i.e., depression and sleep problems) risk factors in an active duty, military sample. Preexisting data from a longitudinal study were analyzed to assess the wellness of service members across the deployment cycle. Participants were 944 active duty service members (95% male, 48% between 18 and 24 years old) who completed surveys upon initial return from deployment and approximately 3 months later. After controlling for other externalizing (alcohol misuse, risk-taking) and internalizing (depression, sleep problems) risk factors, service members reporting aggression were significantly more likely to report suicide ideation than those reporting no aggression (OR = 3.19; OR 95% CI: 1.16-8.80). The independent nature of the relationship between anger and suicidality suggests aggression may be an important indicator of suicidality for service members. Understanding the role of aggression in suicidality may improve the ability to identify at-risk service members and to develop effective interventions to reduce suicide risk.

Comorbidity of Alcohol Use and Other Psychiatric Disorders and Suicide Mortality: Data from the South Korean National Health Insurance Cohort, 2002 to 2013

BACKGROUND

Previous studies have indicated that alcohol use disorder (AUD) and other psychiatric disorders increase the risk of suicide mortality. However, little research has investigated the concomitant effect of comorbid psychiatric disorders on suicide mortality. This study aimed to investigate the effect of comorbid AUD on suicide mortality of individuals with another psychiatric disorder using a national data sample.

METHODS

We used the National Health Insurance Service-National Sample Cohort data from 2002 to 2013. We selected individuals with specific psychiatric disorders based on the International Classification of Diseases, 10th revision (F10-F48). Overall, the study included 741,601 participants. We utilized a prioritization process to identify the primary diagnosis for those with multiple diagnoses. All-cause mortality rates and suicide rates per 100,000 person-year (days) and the standardized mortality ratio (SMR) were calculated. Then, we compared the suicide-specific SMR of 3 different groups: (i) specific psychiatric disorder versus general public; (ii) specific psychiatric disorder comorbid with AUD versus general public; and (iii) specific psychiatric disorder comorbid with AUD versus specific psychiatric disorder without comorbid AUD.

RESULTS

Patients with any specific psychiatric disorder showed higher suicide-specific SMR compared to the general population. Being comorbid with AUD further increased the risk of suicide among psychiatric patients. In particular, patients with bipolar affective disorders, organic mental disorders, or depressive disorders comorbid with AUD had about 2 to 4 times higher suicide-specific SMR compared to those without AUD (bipolar affective disorder: SMR = 3.01, 95% confidence interval (CI) [1.49, 4.54]; organic mental disorder: SMR = 3.43, 95% CI [1.05, 5.81]; depressive disorder: SMR = 2.06, 95% CI [1.52, 2.61]).

CONCLUSIONS

Our data indicate that having a psychiatric disorder increases the risk of committing suicide. More importantly, comorbid AUD further increases this risk of suicidal death for certain psychiatric disorders. This shows the importance of determining whether patients with psychiatric disorders have comorbid AUD to prevent suicide.

[Prevalence and factors associated with alcohol use during pregnancy in a maternity hospital in Goiás, Central Brazil]

The scope of this article is to estimate the prevalence and factors associated with alcohol use during pregnancy. It involved a cross-sectional study in a sample of 361 pregnant women in a reference service for gynecological and prenatal care. The data related to socio-demographic characteristics, alcohol use and potential associated factors were collected through face-to-face interviews. Poisson regression with robust variance was used to identify factors associated with the outcome analyzed. The consumption of alcohol in the sample was 17.7% (95% CI: 95% CI: 14.1% to 22.0%). A history of pre-gestational or gestational diabetes, suicidal ideation and tobacco use in the last 30 days was associated with alcohol use during pregnancy (p < 0.05). The study showed a high prevalence of alcohol use during the current pregnancy and its association with important factors. Actions such as screening for alcohol and advice on problems associated with the use of this substance, especially during the prenatal period, can contribute to effective reduction of alcohol use in pregnant women and related maternal and fetal injuries.

The association of religiosity with suicidal ideation and suicide attempts in the United Kingdom

OBJECTIVE

The goal was to analyze the association of religiosity with suicidal ideation and suicide attempts in a UK nationally representative sample.

METHODS

This study used cross-sectional data from 7403 people who participated in the 2007 Adult Psychiatric Morbidity Survey (APMS). Religion was assessed with the question 'Do you have a specific religion?' with 'yes' and 'no' answer options. Lifetime and past 12-month suicidal ideation and suicide attempts were assessed. The association between religiosity and suicidality was studied in multivariable logistic regression models adjusted for sociodemographic, behavioural, and psychopathological factors.

RESULTS

Compared to those without a religion, the prevalence of past 12-month suicidal ideation (3.2% vs. 5.4%), past 12-month suicide attempts (0.4% vs. 0.9%), lifetime suicidal ideation (11.2% vs. 16.4%), and lifetime suicide attempts (3.6% vs. 6.0%) was lower among those with a religion. In the fully adjusted model, having a religion was significantly associated with lower odds for all types of suicidality except past 12-month suicide attempts: suicidal ideation (past 12-month: OR = 0.71, 95% CI = 0.51-0.99; lifetime: OR = 0.83, 95% CI = 0.69-0.99) and suicide attempts (past 12-month: OR = 0.71, 95% CI = 0.35-1.45; lifetime: OR = 0.69, 95% CI = 0.53-0.90).

CONCLUSION

There is a negative association between religiosity and suicidality in the UK. Future studies should focus on the underlying mechanisms.

On the Neurobiological Role of Oxidative Stress in Alcohol-Induced Impulsive, Aggressive and Suicidal Behavior

Objectives: Alcohol abuse is known to result in behavioral impairments (such as increased impulsivity, aggressive, and suicidal behavior), but the neurobiological basis for these behavioral impairments remains unknown. The objective of this review is to propose a neurobiological basis for alcohol-induced aggression, impulsivity, and suicidal behavior. Methods: Search was done by accessing PubMed/Medline, EBSCO, and PsycINFO databases. The search string used was "(Alcohol OR Alcoholism* OR Alcohol Abuse) AND (Behavior* OR Behavioral Impairment or Disorder) AND (Oxidative Stress OR Reactive Oxygen Species)." The electronic databases were searched for titles or abstracts containing these terms in all published articles between January 1, 1960, and May 31, 2019. The search was limited to studies published in English and other languages involving both animal and human subjects. Articles selected included randomized clinical trials (RCTs), observational studies, meta-analyses, and both systemic and narrative reviews, providing both quantitative and qualitative information with a measure of alcohol abuse or alcoholism as an outcome. Exclusion criteria were unpublished data of any form, including conference proceedings and dissertation. New key terms were identified (new term included: "Antioxidants, Neurotransmitters, Dopamine, Serotonin, GABA, Glutamate. Aggression, Impulsivity, Suicidal Behavior, hippocampus, prefrontal cortex, limbic system, psychiatric disorders, PTSD, Anxiety, Depression. These new terms were searched with Alcohol or Alcoholism or Alcohol Abuse and Oxidative Stress separately resulting in the identification of over 3000 articles. 196 were included in this article. Results: Multiple lines of evidence indicate that oxidative stress (OS) plays a critical underlying role in alcohol toxicity and behavioral impairments. Conclusions/Importance: People diagnosed with PTSD, anxiety disorder, depression, and those with a personality high in psychoticism as measured by the P Scale of the Eysenck Personality Questionnaire, with comorbid alcohol abuse or alcohol use disorder (AUD), may display increased impulsivity, aggression, and suicidal behavior because of the potentiating effect of alcohol-induced OS on their elevated brain oxidative status. Antioxidant therapy should be an integral part of acute alcohol intoxication and AUD treatment. Further research is necessary to fully understand the relationship between OS and alcohol-induced behavioral impairments.

Sequence Analysis of Drug Target Genes with Suicidal Behavior in Bipolar Disorder Patients

Background

A number of genes have been implicated in recent genome-wide association studies of suicide attempt in bipolar disorder. More focused investigation of genes coding for protein targets of existing drugs may lead to drug repurposing for the treatment and/or prevention of suicide.

Methods

We analyzed 2,457 DNA variants across 197 genes of interest to GlaxoSmithKline across the pipeline in our sample of European patients suffering from bipolar disorder (N = 219). We analyzed these variants for a possible association with the suicide severity score (ranging from suicidal ideation/plan to serious suicide attempt) from the Schedule for Clinical Assessment in Neuropsychiatry. We conducted tests of individual variants and gene-based tests.

Results

We found a number of DNA variants in the transforming growth factor beta receptor 1 gene (TGFBR1) to be suggestively associated with suicide severity scores (p < 0.005). The gene-based tests also pointed to TGFBR1 to be associated with suicide severity (p = 0.0001). However, these findings were not replicated in an independent bipolar disorder sample.

Conclusions

We report no significant association between DNA sequences of drug target genes and suicidal behavior. Additional larger sequencing studies could further interrogate associations between variants in drug target genes and suicidal behavior.

A randomized controlled trial of an Internet delivered dialectical behavior therapy skills training for suicidal and heavy episodic drinkers

BACKGROUND

Given that alcohol misuse elevates risk of suicide death among ideators, the paucity of treatment outcome research for individuals presenting with both suicide ideation and problem drinking is particularly troubling. Dialectical behavior therapy (DBT) skills training, which effectively targets behaviors associated with emotion dysregulation including addictive and suicidal behaviors, provides a fitting model amenable to computerization. As stigma and scarcity stand as potential barriers to treatment, online dissemination platforms provide means for efficient treatment delivery that can augment the utility of suitable interventions. This pilot RCT sought to evaluate the feasibility, acceptability, and preliminary efficacy of an Internet-delivered DBT skills training intervention (iDBT-ST) for suicidal individuals who engage in heavy episodic drinking METHODS: Participants (N = 59) were randomized to receive iDBT-ST immediately or after an 8-week waiting period. Clinical outcomes were suicide ideation, alcohol use, and emotion dysregulation.

RESULTS

Participants on average saw a significant reduction in all outcomes over the four-month study period. Compared to waitlist controls, individuals who received iDBT-ST immediately showed faster reductions in alcohol consumption.

CONCLUSIONS

Preliminary results suggest that iDBT-ST may be a viable resource for the high-risk and underserved group represented in this study, and pathways for future development are suggested.

LIMITATIONS

There was difficulty retaining and engaging participants due to technological barriers.

A comprehensive model of predictors of suicide attempt in heavy drinkers: Results from a national 3-year longitudinal study

BACKGROUND

Heavy drinkers are at high risk for suicide attempt and suicide. Multiple factors, when examined in isolation, have been implicated in the risk of suicide attempt in this population. In this report, we present a comprehensive model of the 3-year risk of suicide attempt in heavy drinkers using a longitudinal nationally representative study, the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; wave 1, 2001-2002; wave 2, 2004-2005).

METHODS

We used structural equation modeling to simultaneously examine effects of four broad groups of clinical factors previously identified as potential predictors of attempted suicides: 1) alcohol use disorder severity, 2) severity of comorbidity, 3) sociodemographic characteristics and 4) help-seeking for alcohol problems. Heavy drinking was defined as drinking 5 or more drinks in a day more than once a week in the month prior to Wave 1.

RESULTS

About 1.5% of the 1573 heavy drinker participants (i.e., 5.1% of the NESARC sample) attempted suicide during the 3-year follow-up period. After adjusting for all other factors, several factors independently predicted attempted suicides: the alcohol use disorder liability factor measured by DSM-IV-TR criteria for alcohol abuse and dependence and two dimensions of psychopathology, the general psychopathology factor accounting for the shared effects of all comorbid psychiatric disorders and the externalizing dimension accounting for the shared effects of comorbid substance use disorders. No other factor predicted this risk in addition.

CONCLUSION

This model may help identify individuals with heavy drinking at high risk of suicide and develop more effective suicide prevention strategies.

Choice of a suicide method: Trends and characteristics

The aim of this study was to examine (1) suicide trends by most prevalent methods in Queensland, Australia, during 2000-2015, and (2) characteristics of people by choice of suicide method in 2000-2013. Data were obtained from the Queensland Suicide Register, which includes police and toxicology reports, post-mortem autopsy and Coroner's findings. Poisson and Joinpoint regression were used to study the first aim, and uni-variate and multi-variate logistic regression analyses were applied to investigate the second aim. Suicide method trends showed a significant increase in hanging for both sexes and poisoning with drugs for females, while there was a decline for poisoning by other means for both sexes, and 'other methods' decreased for males. Changes in the trends have altered the order of suicide methods, especially in males. Analyses of 8140 suicides were composed by the choice of method, distinguishable profiles by their demographic, clinical and social characteristics, such as having mental or physical illness or different recent life stressors were identified. This suggests that socio-cultural acceptability, and availability are the key drivers in the choice of suicide methods. Continuing increases in hanging is a big challenge in suicide prevention due to its lethality, easy realisation and its increasing acceptability.

Coping with suicide: a perspective from Scotland

Procedures following suicide differ in Scotland from elsewhere in the UK and we describe the investigation of deaths by procurators fiscal and fatal accident inquiries that may ensue. Higher Scottish suicide rates, and possible reasons for these, are mentioned. Suicide risk cannot be accurately quantified in individual patients but psychiatrists should take the view that good management can collectively reduce the risk among all patients. We comment on practical and emotional issues for clinicians who are coping with the suicide of a patient.

Suicide Risk by Unit Component among Veterans Who Served in Iraq or Afghanistan

This study assessed the risk of suicide by time since separation from the military for US veterans who served in Iraq or Afghanistan. Suicide risk was assessed by comparing the number of suicides among veterans, when stratified by active vs. reserve/National Guard status to the expected number based on rates of suicide in the US general population. Hazard rates were used to assess suicide risk since the time each veteran separated/deactivated from active duty service. Compared to the US general population, active duty veterans had a 56% increased risk of suicide and reserve/National Guard veterans had a 29% increased risk. Suicide risk decreased as time since separation/deactivation increased for both groups. The risk of suicide for both groups was greatest during the first year of follow-up.

Alcohol use by suicide victims in the city of Sao Paulo, Brazil, 2011-2015

Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control which could trigger violent and self-harm behavior, with thus a potential association between alcohol consumption and suicide deaths. The objective of the present study was to assess the association between alcohol consumption and suicide deaths in the city of Sao Paulo, Brazil, from 2011 to 2015, and its relationship with socio-demographic characteristics of the victims and the circumstances of the suicide. A cross-sectional retrospective study was conducted by collection of data from 1,700 suicide victims subjected to examination of blood alcohol concentration (BAC) from toxicology reports from the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Alcohol was detected in blood samples of 30.2% of the victims and mean BAC levels were 1.73 ± 0.08 g/L. The mean age of the victims was 39.90 ± 0.75 years. The majority of the victims were male (74.6%) and the prevalence of positive BAC was higher amongst men (34.7%) than women (17.1%), p<0.05. The majority of the victims were white skinned (64.7%), but there was a higher proportion of victims with positive BAC among mulatto and black individuals, p<0.05. Hanging was the most prevalent suicide method in the sample (48.7%) and amongst men (55.4%), but amongst women it was jumping from a height (35%), p < 0.05.

Acute and chronic alcohol use correlated with methods of suicide in a Swiss national sample

OBJECTIVES

Chronic and acute alcohol use are highly associated risk factors for suicides worldwide. Therefore, we examined suicide cases with and without alcohol use disorder (AUD) using data from the SNSF project "Suicide in Switzerland: A detailed national survey". Our investigations focus on correlations between acute and chronic alcohol use with reference to suicide and potential interactions with the methods of suicide.

METHODS

We used data from the SNSF project in which all cases of registered completed suicide in Switzerland reported to any of the seven Swiss institutes of legal and forensic medicine between 2000 and 2010 were collected. We extracted cases that were tested for blood alcohol to use in our analysis. We compared clinical characteristics, blood alcohol concentrations, and methods of suicide in cases with and without AUD.

RESULTS

Out of 6497 cases, 2946 subjects were tested for acute alcohol use and included in our analysis. Of the latter, 366 (12.4%) persons had a medical history of AUD. Subjects with AUD significantly had higher blood alcohol concentrations and were more often in medical treatment before suicide. Drug intoxication as method of suicide was more frequent in cases with AUD compared to NAUD.

CONCLUSION

Overall, we found a high incidence of acute alcohol use at the time of death in chronic alcohol misusers (AUD). The five methods of suicide most commonly used in Switzerland differed considerably between individuals with and without AUD. Blood alcohol concentrations varied across different methods of suicide independently from the medical history in both groups.

Alcohol Involvement in Suicide and Self-Harm

Abstract. Background: Alcohol misuse and alcohol consumption are significant risk factors for suicidal behavior. Aims: This study sought to identify factors associated with alcohol consumption in cases of suicide and nonfatal self-harm presentations. Method: Suicide cases in Cork, Ireland, from September 2008 to June 2012 were identified through the Suicide Support and Information System. Emergency department presentations of self-harm in the years 2007–2013 were obtained from the National Self-Harm Registry Ireland. Results: Alcohol consumption was detected in the toxicology of 44% out of 307 suicide cases. Only younger age was significantly associated with having consumed alcohol among suicides. Alcohol consumption was noted in the case notes in 21% out of 8,145 self-harm presentations. Logistic regression analyses indicated that variables associated with having consumed alcohol in a self-harm presentation included male gender, older age, overdose as a method, not being admitted to a psychiatric ward, and presenting out-of-hours. Limitations: Data was limited to routinely collected variables by the two different monitoring systems. Conclusion: Alcohol consumption commonly precedes suicidal behavior, and several factors differentiated alcohol-related suicidal acts. Self-harm cases, in particular, differ in profile when alcohol is consumed and may require a tailored clinical approach to minimize risk of further nonfatal or fatal self-harm.

Quality of care measures for the management of unhealthy alcohol use

There is a paucity of quality measures to assess the care for the range of unhealthy alcohol use, ranging from risky drinking to alcohol use disorders. Using a two-phase expert panel review process, we sought to develop an expanded set of quality of care measures for unhealthy alcohol use, focusing on outpatient care delivered in both primary care and specialty care settings. This process generated 25 candidate measures. Eight measures address screening and assessment, 11 address aspects of treatment, and six address follow-up. These quality measures represent high priority targets for future development, including creating detailed technical specifications and pilot testing them to evaluate their utility in terms of feasibility, reliability, and validity.

Unnatural and Violent Death in Cases with High Blood Alcohol Concentration- Autopsy Study

The use of alcohol increases the risk of dying from unnatural or violent causes. The presented study explored the distribution of age, gender, cause, and circumstances of death in persons who died in an unnatural and violent manner, with a blood alcohol concentration (BAC) higher than 0.3 g/dL, and where the cause of death was not alcohol intoxication. We defined the control (0 < BAC < 0.3 g/dL) and study (BAC ≥ 0.3 g/dL) groups, as in subjects with these concentrations, there is a significant risk of gross intoxication, stupor, and death. The subjects from the study group were older, with no difference in gender distribution. Traffic accidents were the most common fatal event in both groups, followed by suicides. Other accidents (choking on food and exposure to fire) were more frequent in the study group. Compared to the control group, subjects from the study group were older persons whose deaths were mainly accidental.

Association Between Lifetime Headache and History of Suicide Attempts in the Elderly

Background

Pain-related conditions have been reported to play a key role among risk factors for suicide. Headache in particular has been repeatedly associated with suicidal thoughts and behaviors. The aims of this study were: 1) to assess the association between lifetime headache (both non-migrainous headache and migraine) and lifetime suicide attempts (SA); 2) to differentiate, within subjects with lifetime SA, patients with and without lifetime headache in terms of socio-demographic and clinical features.

Methods

We studied 1965 subjects from a cohort of community-dwelling persons aged 65 years and over without dementia (the ESPRIT study), divided in two groups: those with (n = 75), and those without a lifetime SA (n = 1890). Logistic regression analyses were used to compare these groups according to lifetime headache status.

Results

After adjusting for gender, living alone, tobacco and alcohol consumption, and depressive, manic/hypomanic and anxiety disorders, lifetime headache frequency was significantly higher in subjects with a lifetime SA compared with controls (OR = 1.92 [1.17–3.15]). Additionally, different factors were identified as being associated with lifetime SA in participants with lifetime headache (female gender, a lower level of high-density lipoprotein cholesterol, insomnia, lifetime major depression) versus participants without headache (glycemia and lifetime major depression).

Conclusions

Lifetime headache was associated with lifetime SA. Subjects who are women and report the co-occurrence of headache and insomnia as well as lifetime major depression require higher attention and a careful screening for suicidal thoughts and behaviors.

Coincident alcohol dependence and depression increases risk of suicidal ideation among Army National Guard soldiers

PURPOSE

Suicide rates among military service members have risen dramatically, while drivers remain poorly understood. We examined the relationship between coincident alcohol dependence and depression in shaping risk of suicidal ideation among National Guard forces.

METHODS

We performed a longitudinal analysis using a randomly selected, population-based sample of Ohio Army National Guard soldiers. Telephone-based surveys of 1582 soldiers who participated in both wave 1 (2008-2009) and wave 2 (2009-2010) were analyzed.

RESULTS

Odds ratios (ORs) for suicidal ideation among those with versus without alcohol dependence were similar among nondepressed (OR = 3.85 [95% confidence intervals (CIs) = 1.18-12.52]) and depressed individuals (OR = 3.13 [95% CI = 0.88-11.14]); multiplicative interaction was not observed. In contrast, the risk differences (RDs) among those with versus without alcohol dependence diverged for those without depression (RD = 0.04 [95% CI = 0.02-0.07]) compared with those with depression (RD = 0.11 [95% CI = 0.06-0.18]); strong evidence of additive interaction was observed.

CONCLUSIONS

We found that alcohol dependence and depression interact statistically in shaping risk for incident suicidal ideation among Army National Guard service members. A high-risk prevention approach including population-based screening for suicidality among patients with alcohol dependence, depression, and particularly those with both conditions is warranted in military populations.

Alcohol Consumption as a Risk Factor for Suicidal Behavior: A Systematic Review of Associations at the Individual and at the Population Level

The objective of this study was to provide an updated review of the magnitude of the relationship between alcohol use and suicidal behaviour at the individual and the population level. Systematic literature searches retrieved 14 reviews of individual level studies and 16 primary population level studies. Alcohol abuse and alcohol intoxication are often present in suicidal behaviour; risk of suicide is elevated in alcohol abusers and increasing population drinking tends to be associated with increase in suicide rates. Estimated magnitude of the relationship differs for men and women and it varies at the population level across cultures with different drinking pattern. These variations probably reflect gender differences and cultural variation in drinking behavior generally. Empirical evidence for a causal relationship is still urgently needed.

Recent Advances in Means Safety as a Suicide Prevention Strategy

Despite advances in theory and the development and implementation of evidence-based treatments, the United States suicide rate has been rising continuously for over a decade. Although this does not indicate that traditional treatment approaches should be abandoned, it does highlight the need to supplement such approaches with alternatives. One seemingly highly valuable option is means safety, defined as the reduced access to and/or increased safe storage of potentially lethal methods for suicide. This paper provides a review of the current literature on the prevalence of six methods for suicide and preventative efforts aimed to reduce suicide rates. The majority of means safety interventions seem promising given that these methods are common and highly lethal. However, cultural and practical barriers will need to be taken into consideration when implementing these plans. Overall, means safety efforts and preventative measures seem to be promising ways to reduce the national suicide rate if implemented.

Alcohol Policies and Suicide: A Review of the Literature

Both intoxication and chronic heavy alcohol use are associated with suicide. There is extensive population-level evidence linking per capita alcohol consumption with suicide. While alcohol policies can reduce excessive alcohol consumption, the relationship between alcohol policies and suicide warrants a critical review of the literature. This review summarizes the associations between various types of alcohol policies and suicide, both in the United States and internationally, as presented in English-language literature published between 1999 and 2014. Study designs, methodological challenges, and limitations in ascertaining the associations are discussed. Because of the substantial between-states variation in alcohol policies, U.S.-based studies contributed substantially to the literature. Repeated cross-sectional designs at both the ecological level and decedent level were common among U.S.-based studies. Non-U.S. studies often used time series data to evaluate pre-post comparisons of a hybrid set of policy changes. Although inconsistency remained, the published literature in general supported the protective effect of restrictive alcohol policies on reducing suicide as well as the decreased level of alcohol involvement among suicide decedents. Common limitations included measurement and selection bias and a focus on effects of a limited number of alcohol policies without accounting for other alcohol policies. This review summarizes a number of studies that suggest restrictive alcohol policies may contribute to suicide prevention on a general population level and to a reduction of alcohol involvement among suicide deaths.

Symptoms of Alcohol Dependence Predict Suicide Ideation Among Alaskan Undergraduates

Abstract. Background: Previous research has demonstrated an association between alcohol-related problems and suicidal ideation (SI). Aims: The present study evaluated, simultaneously, alcohol consequences and symptoms of alcohol dependence as predictors of SI after adjusting for depressive symptoms and alcohol consumption. Method: A sample of 298 Alaskan undergraduates completed survey measures, including the Young Adult Alcohol Consequences Questionnaire, the Short Alcohol Dependence Data Questionnaire, and the Beck Depression Inventory – II. The association between alcohol problems and SI status was evaluated using sequential logistic regression. Results: Symptoms of alcohol dependence (OR = 1.88, p < .05), but not alcohol-related consequences (OR = 1.01, p = .95), emerged as an independent predictor of SI status above and beyond depressive symptoms (OR = 2.39, p < .001) and alcohol consumption (OR = 1.08, p = .39). Conclusion: Alcohol dependence symptoms represented a unique risk for SI relative to alcohol-related consequences and alcohol consumption. Future research should examine the causal mechanism behind the relationship between alcohol dependence and suicidality among university students. Assessing the presence of dependence symptoms may improve the accuracy of identifying students at risk of SI.

Substance misuse in life and death in a 2-year cohort of suicides

BACKGROUND

Although substance misuse is a key risk factor in suicide, relatively little is known about the relationship between lifetime misuse and misuse at the time of suicide.

AIMS

To examine the relationship between substance misuse and subsequent suicide.

METHOD

Linkage of coroners' reports to primary care records for 403 suicides occurring over 2 years.

RESULTS

With alcohol misuse, 67% of the cohort had previously sought help for alcohol problems and 39% were intoxicated at the time of suicide. Regarding misuse of other substances, 54% of the cohort was tested. Almost one in four (38%) tested positive, defined as an excess of drugs over the prescribed therapeutic dosage and/or detection of illicit substances. Those tested were more likely to be young and have a history of drug misuse.

CONCLUSIONS

A deeper understanding of the relationship between substance misuse and suicide could contribute to prevention initiatives. Furthermore, standardised toxicology screening processes would avoid diminishing the importance of psychosocial factors involved in suicide as a 'cause of death'.

Outpatient treatment of alcohol use disorders among subjects 60+ years: design of a randomized clinical trial conducted in three countries (Elderly Study)

BACKGROUND

The proportion of 60+ years with excessive alcohol intake varies in western countries between 6-16 % among men and 2-7 % among women. Specific events related to aging (e.g. loss of job, physical and mental capacity, or spouse) may contribute to onset or continuation of alcohol use disorders (AUD). We present the rationale and design of a multisite, multinational AUD treatment study for subjects aged 60+ years.

METHODS/DESIGN

1,000 subjects seeking treatment for AUD according to DSM-5 in outpatient clinics in Denmark, Germany, and New Mexico (USA) are invited to participate in a RCT. Participants are randomly assigned to four sessions of Motivational Enhancement Treatment (MET) or to MET plus an add-on with eight sessions based on the Community Reinforcement Approach (CRA), which include a new module targeting specific problems of older adults. A series of assessment instruments is applied, including the Form-90, Alcohol Dependence Scale, Penn Alcohol Craving Scale, Brief Symptom Inventory and WHO Quality of Life. Enrolment will be completed by April 2016 and data collection by April 2017. The primary outcome is the proportion in each group who are abstinent or have a controlled use of alcohol six months after treatment initiation. Controlled use is defined as maximum blood alcohol content not exceeding 0.05 % during the last month. Total abstinence is a secondary outcome, together with quality of life andcompliance with treatment.

DISCUSSION

The study will provide new knowledge about brief treatment of AUD for older subjects. As the treatment is manualized and applied in routine treatment facilities, barriers for implementation in the health care system are relatively low. Finally, as the study is being conducted in three different countries it will also provide significant insight into the possible interaction of service system differences and related patient characteristics in predictionof treatment outcome.

TRIAL REGISTRATION
